Zhong Y, Li J, Zhu X, Huang N, Liu R, Sun R. A comprehensive review of bupleuri radix and its bioactive components: with a major focus on treating chronic liver diseases. JOURNAL OF ETHNOPHARMACOLOGY 2024; 330:118244. [PMID: 38663781 DOI: 10.1016/j.jep.2024.118244] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/02/2023] [Revised: 04/19/2024] [Accepted: 04/22/2024] [Indexed: 04/30/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Bupleuri Radix (BR) has been recognized as an essential herbal medicine for relieving liver depression for thousands of years. Contemporary research has provided compelling evidence of its pharmacological effects, including anti-inflammatory, immunomodulatory, metabolic regulation, and anticancer properties, positioning it as a promising treatment option for various liver diseases. Hepatitis, steatohepatitis, cirrhosis, and liver cancer are among the prevalent and impactful liver diseases worldwide. However, there remains a lack of comprehensive systematic reviews that explore the prescription, bio-active components, and underlying mechanisms of BR in treating liver diseases. AIM OF THE REVIEW To summarize the BR classical Chinese medical prescription and ingredients in treating liver diseases and their mechanisms to inform reference for further development and research. MATERIALS AND METHODS Literature in the last three decades of BR and its classical Chinese medical prescription and ingredients were collated and summarized by searching PubMed, Wiley, Springer, Google Scholar, Web of Science, CNKI, etc. RESULTS: BR and its classical prescriptions, such as Xiao Chai Hu decoction, Da Chai Hu decoction, Si Ni San, and Chai Hu Shu Gan San, have been utilized for centuries as effective therapies for liver diseases, including hepatitis, steatohepatitis, cirrhosis, and liver cancer. BR is a rich source of active ingredients, such as saikosaponins, polysaccharides, flavonoids, sterols, organic acids, and so on. These bioactive compounds exhibit a wide range of beneficial effects, including anti-inflammatory, antioxidant, immunomodulatory, and lipid metabolism regulation. However, it is important to acknowledge that BR and its constituents can also possess hepatotoxicity, which is associated with cytochrome P450 (CYP450) enzymes and oxidative stress. Therefore, caution should be exercised when using BR in therapeutic applications to ensure the safe and appropriate utilization of its potential benefits while minimizing any potential risks. CONCLUSIONS To sum up, BR, its compounds, and its based traditional Chinese medicine are effective in liver diseases through multiple targets, multiple pathways, and multiple effects. Advances in pharmacological and toxicological investigations of BR and its bio-active components in the future will provide further contributions to the discovery of novel therapeutics for liver diseases.

Abstract
The liver is exposed to several harmful substances that bear the potential to cause excessive liver damage ranging from hepatitis and non-alcoholic fatty liver disease to extreme cases of liver cirrhosis and hepatocellular carcinoma. Liver ailments have been effectively treated from very old times with Chinese medicinal herbal formulations and later also applied by controlled trials in Japan. However, these traditional practices have been hardly well characterized in the past till in the last decades when more qualified studies have been carried out. Modern advances have given rise to specific molecular targets which are specifically good candidates for affecting the intricate mechanisms that play a role at the molecular level. These therapeutic regimens that mainly affect the progression of the disease by inhibiting the gene expression levels or by blocking essential molecular pathways or releasing cytokines may prove to play a vital role in minimizing the tissue damage. This review, therefore, tries to throw light upon the variation in the therapies for the treatment of benign and malignant liver disease from ancient times to the current date. Nonetheless, clinical research exploring the effectiveness of herbal medicines in the treatment of benign chronic liver diseases as well as prevention and treatment of HCC is still warranted.

Systematic analysis of the mechanism of Xiaochaihu decoction in hepatitis B treatment via network pharmacology and molecular docking. Comput Biol Med 2021; 138:104894. [PMID: 34607274 DOI: 10.1016/j.compbiomed.2021.104894] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Revised: 09/18/2021] [Accepted: 09/22/2021] [Indexed: 12/18/2022]
Abstract
Hepatitis B (HB) is a globally prevalent infectious disease caused by the HB virus. Xiaochaihu decoction (XCHD) is a classic herbal formula with a long history of clinical application in treating HB. Although the anti-HB activity of XCHD has been reported, systematic research on the exact mechanism of action is lacking. Here, a network pharmacology-based approach was used to predict the active components, important targets, and potential mechanism of XCHD in HB treatment. Investigation included drug-likeness evaluation; absorption, distribution, metabolism, and elimination (ADME) screening; protein-protein interaction (PPI) network construction and cluster analysis; Gene Ontology (GO) analysis; and Kyoto Encyclopedia of Genes and Genomes (KEGG) annotation. Molecular docking was adopted to investigate the interaction between important target proteins and active components. Eighty-seven active components of XCHD and 155 anti-HB targets were selected for further analysis. The GO enrichment and similarity analysis results indicated that XCHD might perform similar or the same GO functions. Glycyrrhizae Radix (GR), one of the seven XCHD herbs, likely exerts some unique GO functions such as the regulation of interleukin-12 production, positive regulation of interleukin-1 beta secretion, and regulation of the I-kappaB/NF-kappaB complex. The PPI network and KEGG pathway analysis results showed that XCHD affects HB mainly through modulating pathways related to viral infection, immunity, cancer, signal transduction, and metabolism. Additionally, molecular docking verified that the active compounds (quercetin, chrysin, and capsaicin) could bind with the key targets. This work systematically explored the anti-HB mechanism of XCHD and provides a novel perspective for future pharmacological research.

Abstract
Previous studies have shown that serum total cholesterol (TC) and serum alanine aminotransferase (ALT) are associated with liver cancer risk. However, the common contribution of TC and normal-high ALT to primary liver cancer (PLC) has not been reported. We aim to assess the separate and joint effect of low TC level and normal-high ALT level on the risk of PLC, a large prospective cohort was conducted in our study.The participants were divided into 4 groups via the cross-matching method according to TC [low level (-)/non-low level (+)] and ALT [normal level (-)/normal-high level(+)] status, and using the lower quartile value of TC and the upper quartile value of ALT as a threshold, respectively. Incident PLC was confirmed by review of medical records. Cox proportional hazards regression models and interactive additive models were used to evaluate whether the joint effect of low TC level and normal-high ALT level is associated with the risk of PLC.During 1,248,895 person-years follow-up, 298 participants were diagnosed with PLC among 114,972 subjects. In male population, TC < 4.24 mmol/L was group "TC (-)"; TC ≥ 4.24 mmol/L was group "TC (+)"; ALT < 23 U/L was group "ALT (-)": 33 U/L ≥ ALT ≥ 23 U/L was group "ALT (+)". Compared with the group "TC (+)", group "ALT (-)", respectively, the adjusted hazard ratio (HR) and 95% confidence interval (95%CI) for PLC risk was 1.74 (1.36-2.25) in group "TC (-)" and 1.49 (1.15-1.94) in group "ALT (+)". In combinatorial analysis, compared with group "TC (+) and ALT (-)", the significant increased risk of PLC were observed in group "TC (+) and ALT (+)" (HR = 1.41; 95% confidence intervals [CI]: 1.02-1.95), group "TC (-) and ALT (-)" (HR = 1.67; 95%CI: 1.24-2.27) and group "TC (-) and ALT (+)" (HR = 2.72; 95%CI: 1.81-4.09), respectively. However, no statistical significance was found among female.The separate and joint effect of low TC level and normal-high ALT level was observed for PLC risk in males. When combined, individuals with coexistence of low TC level and normal-high ALT level significantly increase the risk of PLC.

Abstract
BACKGROUND Herbal medicine plays an important role in health, particularly in remote parts of developing areas with few health facilities. According to WHO estimates, about three-quarters of the world's population currently use herbs or traditional medicines to treat various ailments, including liver diseases. Several studies have found that the use of medicinal plants was effective in the treatment of infectious and non-infectious diseases. Hepatitis and liver cirrhosis associated with many clinical manifestations can be treated with allopathic medicines, but reports of a number of side effects including immunosuppression, bone marrow suppression, and renal complications have motivated researchers to explore more natural herbal medicines with low or no side effects and with high efficacy in treating hepatic diseases. METHODS Databases including PubMed, Medline, and Google Scholar were searched for findings on the hepatoprotective effects of plants. RESULTS Various medicinal plants are used for the treatment of liver disorders. The range of alternative therapies is huge, and they are used worldwide, either as part of primary health care or in combination with conventional medicine. Hepatoprotective plants contain a variety of chemical constituents including flavonoids, alkaloids, glycosides, carotenoids, coumarins, phenols, essential oil, organic acids, monoterpenes, xanthenes, lignans, and lipids. CONCLUSION This review shows that numerous plants are found to contain hepatoprotective compounds. However, further studies are needed to determine their association with existing regimes of antiviral medicines and to develop evidence-based alternative medicine to cure different kinds of liver disease in humans.

Abstract
Background: Xiao-Chai-Hu Tang (XCHT) is an extract of seven herbs with anticancer properties, but its mechanism of action is unknown. In this study, we evaluated XCHT-treated hepatocellular carcinoma (HCC) for anti-proliferative and pro-apoptotic effects. Materials and Methods: Using a hepatic cancer xenograft model, we investigated the in vivo efficacy of XCHT against tumor growth by evaluating tumor volume and weight, as well as measuring apoptosis and cellular proliferation within the tumor. To study the effects of XCHT in vitro, we measured the cell viability of XCHT-treated Huh7 cells, as well as colony formation and apoptosis. To identify a potential mechanism of action, the gene and protein expression levels of Bax, Bcl-2, CDK4 and cyclin-D1 were measured in XCHT-treated Huh7 cells. Results: We found that XCHT reduced tumor size and weight, as well as significantly decreased cell viability both in vivo and in vitro. XCHT suppressed the expression of the proliferation marker Ki-67 in HCC tissues and inhibited Huh7 colony formation. XCHT induced apoptosis in HCC tumor tissues and in Huh7 cells. Finally, XCHT altered the expression of Bax, Bcl-2, CDK4 and cyclin-D1, which halted cell proliferation and promoted apoptosis. Conclusion: Our data suggest that XCHT enhances expression of pro-apoptotic pathways, resulting in potent anticancer activity.

Abstract
Oxidative stress has been investigated in the context of alcoholic liver injury for many years and shown to be a causal factor of chronic hepatitis C (CHC), nonalcoholic steatohepatitis (NASH), drug-induced liver injury, Wilson’s disease, and hemochromatosis. In CHC, it has been demonstrated that oxidative stress plays an important role in hepatocarcinogenesis. In cases with persistent hepatitis due to failure of hepatitis C virus eradication, or chronic liver disease, such as NASH, the treatment of which remains unestablished, it is important to reduce serum alanine aminotransferase levels and prevent liver fibrosis and development of hepatocellular carcinoma. This also suggests the importance of antioxidant therapy. Among treatment options where it would be expected that anti-inflammatory activity plays a role in their confirmed efficacy for chronic hepatitis, iron depletion therapy, glycyrrhizin, ursodeoxycholic acid, Sho-Saiko-To, and vitamin E can all be considered antioxidant therapies. To date, however, the ability of these treatments to prevent cancer has been confirmed only in CHC. Nevertheless, anti-inflammatory and anti-fibrotic effects have been demonstrated in other liver diseases and these therapies may potentially be effective for cancer prevention.

Abstract
Few studies have investigated the effects of Japanese herbal medicines on nonalcoholic fatty liver disease (NAFLD)/nonalcoholic steatohepatitis (NASH). To the best of our knowledge, only one study has examined whether high-fat (HF) diet-fed db/db mice are appropriate animal models of NASH. We investigated the effects of four types of Japanese herbal medicines (shosaikoto (TJ-9), inchinkoto (TJ-135), juzentaihoto (TJ-48), and keishibukuryogan (TJ-25)) on hepatic lesions of HF diet-fed db/db mice. Db/db mice were divided into six groups: control diet (control); HF diet (HF); and HF diet supplemented with TJ-9, TJ-135, TJ-48, or TJ-25 (TJ-9, TJ-135, TJ-48, and TJ-25, respectively). Mice were killed after 6 weeks of treatment, and biochemical and pathological analyses were performed. Mice in the HF group consistently developed histopathological features consistent with definite NASH, and marked necroinflammation occurred. Serum alanine aminotransferase levels in the TJ-9, TJ-135, and TJ-48 groups were significantly improved compared with those in the HF group. With regard to liver histology, TJ-9 and TJ-48 significantly improved lobular inflammation, and TJ-135 significantly improved ballooning degeneration. We have shown that HF diet-fed db/db mice are animal models that correctly recapitulate the histopathology of human NASH and that TJ-9, TJ-135, and TJ-48 inhibit necroinflammatory activity in this model.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Liver fibrosis has been recognized as a major lesion of the liver that leads to liver cirrhosis at the end stage. Soshiho-tang (SST) has been used to improve liver fibrosis/cirrhosis by ameliorating fibrosis-specific markers. This study aimed to assess the efficacy of SST on liver fibrosis/cirrhosis through a systematic review of the literature and meta-analysis using animal models. MATERIALS AND METHODS Studies of SST treatment in liver fibrosis/cirrhosis-induced animal models were searched by electronic data bases. The quality of the studies included was assessed and the efficacy of SST was evaluated based on markers from liver tissues and serum. RESULTS Among the 838 studies identified in the literature search, 20 studies that met the inclusion criteria were included in the analysis. SST significantly reduced the elevated levels of fibrosis markers, such as the degree of fibrosis, hydroxyproline, hyaluronic acid, transforming growth factor-β1, and procollagen III in liver tissues, and aspartate aminotransferase, alanine aminotransferase, procollagen III, tissue inhibitor of metalloproteinase-1, and type IV collagen in the serum. CONCLUSIONS SST was effective in decreasing pathologically increased markers in animal models of liver fibrosis/cirrhosis. A larger-scale of animals, well-designed animal study is expected to improve the methodological quality, heterogeneity, and potential biases of the meta-analysis.

Abstract
Although Japanese herbal medicines (JHMs) are widely used in Japan, only a few studies have investigated their effects on nonalcoholic steatohepatitis (NASH). In the present study, we examined the effect of 4 kinds of JHMs [sho-saiko-to (TJ-9), inchin-ko-to (TJ-135), juzen-taiho-to (TJ-48), and keishi-bukuryo-gan (TJ-25)] on a mouse model of NASH. Db/db mice were divided into 6 groups: control diet (control), methionine- and choline-deficient diet (MCD), and MCD diet supplemented with TJ-9, TJ-135, TJ-48, and TJ-25 (TJ-9, TJ-135, TJ-48, and TJ-25, respectively). All mice were sacrificed after 4 weeks of treatment, and biochemical, pathological, and molecular analyses were performed. Serum alanine aminotransferase levels and liver histology, including necroinflammation and fibrosis, were significantly alleviated in the TJ-9 and TJ-48 groups compared with the MCD group. The expression level of transforming growth factor (TGF)-β1 mRNA in the liver was significantly suppressed by TJ-48. Although the differences were not statistically significant, the expression levels of tumor necrosis factor (TNF)-α and interleukin (IL)-6 were lower, and those of peroxisome proliferators-activated receptor (PPAR)γ were higher in the TJ-9 and/or TJ-48 groups than in the MCD group. Similarly, even though the results were not statistically significant, malondialdehyde levels in liver tissues were lower in the TJ-9 and TJ-48 groups than in the MCD group. We showed that JHMs, especially TJ-9 and TJ-48, inhibited the necroinflammation and fibrosis in the liver of a mouse model of NASH, even though the mechanisms were not fully elucidated. Further studies are needed in the future to investigate the possibility of clinical application of these medicines in the treatment for NASH.

Song KH, Kim YH, Kim BY. Sho-saiko-to, a traditional herbal medicine, regulates gene expression and biological function by way of microRNAs in primary mouse hepatocytes. BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2014; 14:14. [PMID: 24410935 PMCID: PMC3893506 DOI: 10.1186/1472-6882-14-14] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/16/2013] [Accepted: 12/31/2013] [Indexed: 12/25/2022]
Abstract
BACKGROUND Sho-saiko-to (SST) (also known as so-shi-ho-tang or xiao-chai-hu-tang) has been widely prescribed for chronic liver diseases in traditional Oriental medicine. Despite the substantial amount of clinical evidence for SST, its molecular mechanism has not been clearly identified at a genome-wide level. METHODS By using a microarray, we analyzed the temporal changes of messenger RNA (mRNA) and microRNA expression in primary mouse hepatocytes after SST treatment. The pattern of genes regulated by SST was identified by using time-series microarray analysis. The biological function of genes was measured by pathway analysis. For the identification of the exact targets of the microRNAs, a permutation-based correlation method was implemented in which the temporal expression of mRNAs and microRNAs were integrated. The similarity of the promoter structure between temporally regulated genes was measured by analyzing the transcription factor binding sites in the promoter region. RESULTS The SST-regulated gene expression had two major patterns: (1) a temporally up-regulated pattern (463 genes) and (2) a temporally down-regulated pattern (177 genes). The integration of the genes and microRNA demonstrated that 155 genes could be the targets of microRNAs from the temporally up-regulated pattern and 19 genes could be the targets of microRNAs from the temporally down-regulated pattern. The temporally up-regulated pattern by SST was associated with signaling pathways such as the cell cycle pathway, whereas the temporally down-regulated pattern included drug metabolism-related pathways and immune-related pathways. All these pathways could be possibly associated with liver regenerative activity of SST. Genes targeted by microRNA were moreover associated with different biological pathways from the genes not targeted by microRNA. An analysis of promoter similarity indicated that co-expressed genes after SST treatment were clustered into subgroups, depending on the temporal expression patterns. CONCLUSIONS We are the first to identify that SST regulates temporal gene expression by way of microRNA. MicroRNA targets and non-microRNA targets moreover have different biological roles. This functional segregation by microRNA would be critical for the elucidation of the molecular activities of SST.

Xiaochaihu Decoction attenuates the vicious circle between the oxidative stress and the ALP inactivation through LPS-catecholamines interactions in gut, liver and brain during CCI4+ethanol-induced mouse HCC. BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 13:375. [PMID: 24373196 PMCID: PMC3884004 DOI: 10.1186/1472-6882-13-375] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/09/2013] [Accepted: 11/13/2013] [Indexed: 01/13/2023]
Abstract
BACKGROUND Xiaochaihu Decoction (XCHD) prevents hepatocarcinogenesis in association with inhibition of oxidative stress. However, alkaline phosphatase (ALP) activity, lipopolysaccharides (LPS)-catecholamines (CA) interactions in gut, liver and brain may play an important role in the status of oxidative stress. This study was to assess whether XCHD attenuates the vicious circle between oxidative stress and ALP inactivation through LPS-CA interactions. METHODS Hepatocellular carcinoma group (HCC) were induced by CCI4 + ethanol; HCC with Liver Depression and Spleen Deficiency (HCC + LDSD) were induced by squeezing tails (30 min/day), solitary breeding and intermittent fasting on the basis of HCC; XCHD was administered after 4 weeks of the HCC + LDSD. The degree of tissue injury were studied using a scoring system, and brain weights were measured. Peroxynitrite (ONOO(-)), malondialdehyde (MDA), 4-hydroxy-3-methoxymandelic acid (VMA, CA metabolites), lipopolysaccharide-phosphate (LPS-P), ALP activity (ALP-A) and Concanavalin A (ConA)-binding rate of ALP (ALP-C) were determined by colorimetric method and lectin (ConA) affinity precipitation method. RESULTS More injuries and ONOO(-), MDA, VMA, LPS-P, ALP-C were increased, ALP-A were decreased in the gut, liver and brain of HCC group, the most in HCC + LDSD group, after treatment with XCHD, all of which were improved. A positive association found between gut-liver-brain injury and ONOO(-), MDA, VMA, LPS-P, ALP-C, between ONOO(-), MDA, VMA, LPS-P and ALP-C in the gut, liver and brain, and a negative association found between gut-liver-brain injury and ALP-A, between ALP-A and ONOO(-), MDA, VMA, LPS-P, ALP-C in the gut, liver and brain. CONCLUSIONS XCHD can attenuates the vicious circle between the oxidative stress, nitrosative stress, N-glycan deficiency and inactivation of ALP through LPS-CA interactions in gut, liver and brain.

Evaluation of oral subchronic toxicity of soshiho-tang water extract: the traditional herbal formula in rats. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 2013:590181. [PMID: 23573136 PMCID: PMC3616347 DOI: 10.1155/2013/590181] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/04/2012] [Accepted: 02/20/2013] [Indexed: 02/07/2023]
Abstract
Soshiho-tang (Xiao-chai-hu-tang in Chinese and Sho-saiko-to in Japanese) has been widely used for its various pharmacological effects, which include anti-inflammatory, antioxidant, antihepatic fibrosis, and antitumor properties. To evaluate the safety of Soshiho-tang water extract (SST), we tested its subchronic toxicity in male and female Crl:CD (SD) rats. Rats were orally treated with four different doses (0, 500, 1000, and 2000 mg/kg/day) of SST administered for 13 weeks. Mortality, clinical signs, body weight changes, food and water consumption changes, ophthalmology, urinalysis, hematological and biochemical parameters, gross findings, organ weights, and histological markers were monitored during the study. The SST treatment did not result in any toxicologically significant changes in mortality, clinical signs, body weights, food and water consumption, ophthalmoscopy, urinalysis, hematological and serum biochemical parameters, gross findings, organ weights, or histopathology. Histological analysis did not show any liver or kidney alteration. We concluded that the 13-week repeated oral administration of SST did not cause any adverse effects in rats at dosage levels of ≤2000 mg/kg/day. Under these experimental conditions, the no-observed-adverse-effect level was concluded to be 2000 mg/kg/day for both sexes.

Abstract
Backgroud Soshiho-tang (SST, Xiao-chai-hu-tang in Chinese and Sho-saiko-to in Japanese), an oriental herbal formula, is used for treatment of chronic liver diseases. Although many researchers have studied the pharmacological properties of SST, information about its safety and toxicity is limited. Therefore, we evaluated the potential safety of SST in Sprague–Dawley rats over a period of 4-weeks. Methods The SST was administered once daily by gavage to male and female rats at doses of 0, 500, 1000 and 2000 mg/kg/day for 4 weeks. We measured the body weight, mortality, food consumption, ophthalmoscopy, urinalysis, hematology, serum biochemistry, gross pathological findings, absolute/relative organ weights and histopathology. In addition, we analyzed the component of SST and measured the stability of its component in SST according to study periods using high performance liquid chromatography. Results The SST treatment did not result in any toxicologically significant changes in mortality, food consumption, ophthalmoscopy, urinalysis, hematology, serum biochemistry, gross pathological findings, absolute/relative organ weights and histopathology, except for salivation and reduction in body weight in the 2000 mg/kg/day male group. These findings in the 2000 mg/kg/day male group are considered toxicologically insignificant because they are not accompanied by other pathological findings, including in hematology, serum biochemistry and histopatholgy, and they do not exhibit a dose–response relationship. SST is detected three components including liquiritin, baicalin, and glycyrrhizin. In addition, there were not observed the significant differences among the contents of three components in SST according to storage periods. Conclusion These results indicate that SST may be a safe material. Based on these results, the no-observed-adverse-effect level was more than 2000 mg/kg for both genders.

Abstract
Herbal medicines have been used clinically in Eastern Asia, and traditional Japanese herbal (Kampo) formulas are approved as ethical drugs. The Kampo formulas are mixtures of the crude extracts of several herbs, each of which contains multiple components. Numerous investigators have reported that some herbal medicines are efficacious for treating several human diseases. We reviewed the literature on traditional herbal medicines and treatment of ocular diseases. Oral Orengedoku-to and Kakkon-to inhibit postoperative uveitis in humans. Oral Goshajinki-gan improved ocular surface disorders in patients with type 1 diabetes mellitus. Oral Hachimijio-gan increased retinal blood flow. Keishi-bukuryo-gan Sho might be associated with vitreoretinopathy in patients with type 2 diabetes mellitus. Oral Hachimijio-gan and Goshajinki-gan delayed lens opacification in rats and mice. Oral Sairei-to, Orengedoku-to, Senkanmeimoku-to, Scutellariae radix extract, Gardeniae fructus extract, topical Liguisticum wallichii rhizoma extract, and intravenous injection of tetramethylpyrazine, baicalin, baicalein, wogonin, and crocetin inhibited some forms of experimental uveitis in rabbits. Topical glycyrrhizinate improved allergic conjunctivitis in humans and rats. Oral crocetin improved eyestrain in humans. Oral berberine diminished experimental uveitis in rats. Baicalein, wogonin, berberine, and berberrubine inhibited in vitro expression of several cytokines in cultured retinal pigment epithelial cells. Some Kampo formulas are efficacious for treating several ocular diseases in humans and animals. Some herbal extracts and their components inhibit some forms of experimental uveitis.

Abstract
Diethylnitrosamine (DEN) is a potent hepatotoxin and hepatocarcinogen in animals and possible in humans. Estrogen has been reported to play a protective role against DEN exposure. Osteopontin (OPN), a downstream molecular of estrogen, plays a role in many pathophysiological processes. In this study, we evaluate the role of OPN in estrogen-mediated hepatoprotection in DEN-treated mice. DEN was administrated intraperitoneally to C57BL/6 and OPN(-/-) mice. Compared to male mice, female mice exhibited significantly higher hepatic OPN expression with less liver damage 48 h after DEN treatment. Interestingly, enhanced OPN expression was predominantly detected in hepatocytes after DEN treatment. OPN deficiency enhanced the susceptibility to DEN, which was more apparent in females than males. Estrogen-mediated protection against DEN in males was abrogated by OPN deficiency. The protective activities of estrogen could be mimicked by exogenous OPN. Consistent with liver injury, oxidative stress in liver was enhanced with OPN depletion. OPN reduced DEN-induced oxidative stress likely through inhibition of CYP2A5 expression. In conclusion, we demonstrate that OPN may be involved in estrogen-mediated hepatoprotection in DEN-induced liver injury through enhancement of hepatocyte survival and inhibition of DEN biotransformation. Our findings may provide new insight into gender differences in chemical-induced liver injury and related diseases.

Renal protective effect of xiao-chai-hu-tang on diabetic nephropathy of type 1-diabetic mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2012; 2012:984024.

Abstract
Xiao-Chai-Hu-Tang (XCHT), a traditional Chinese medicine formula consisting of seven medicinal plants, is used in the treatment of various diseases. We show here that XCHT could protect type-1 diabetic mice against diabetic nephropathy, using streptozotocin (STZ)-induced diabetic mice and high-glucose (HG)-exposed rat mesangial cell (RMC) as models. Following 4 weeks of oral administration with XCHT, renal functions and renal hypertrophy significantly improved in the STZ-diabetic mice, while serum glucose was only moderately reduced compared to vehicle treatment. Treatment with XCHT in the STZ-diabetic mice and HG-exposed RMC resulted in a decrease in expression levels of TGF-β1, fibronectin, and collagen IV, with concomitant increase in BMP-7 expression. Data from DPPH assay, DHE stain, and CM-H2DCFDA analysis indicated that XCHT could scavenge free radicals and inhibit high-glucose-induced ROS in RMCs. Taken together, these results suggest that treatment with XCHT can improve renal functions in STZ-diabetic mice, an effect that is potentially mediated through decreasing oxidative stress and production of TGF-β1, fibronectin, and collagen IV in the kidney during development of diabetic nephropathy. XCHT, therefore merits further investigation for application to improve renal functions in diabetic disorders.

Abstract
The traditional Chinese herbal medicine Sho-saiko-to is a mixture of seven herbal preparations that has long been used in the treatment of chronic liver disease. Various clinical trials have shown that Sho-saiko-to protects against the development of hepatocellular carcinoma in cirrhotic patients. However, the mechanism by which Sho-saiko-to protects hepatocytes against hepatic fibrosis and carcinoma is not yet known. Basic science studies have demonstrated that Sho-saiko-to reduces hepatocyte necrosis and enhances liver function. Sho-saiko-to significantly inhibits hepatic fibrosis by inhibiting the activation of stellate cells, the major producers of collagen in the liver, as well as by inhibiting hepatic lipid peroxidation, promoting matrix degradation, and suppressing extracellular matrix (ECM) accumulation. Furthermore, clinical trials have shown that Sho-saiko-to lowers the rate of hepatocellular carcinoma (HCC) development in patients with cirrhosis and increases the survival of patients with HCC. Unfortunately, some case reports have shown the side effects of Sho-saiko-to. Most of the side effects were interstitial pneumonia and acute respiratory failure induced by Sho-saiko-to in Japan. As a result of analyzing these case reports, the incidence and risk are increased by co-administration of interferon, duration of medication, and, high in an elderly population. This review discusses the properties of Sho-saiko-to with regards to the treatment of chronic liver diseases and suggests the side effects of Sho-saiko-to.

Abstract
Use of herbal medicine in the treatment of liver cancer has a long tradition. The compounds derived from the herb and herbal composites are of considerable interest among oncologists. In the past, certain herbal compounds and herbal composite formulas have been studied through in vitro and in vivo as an anti-hepatocellular carcinoma (HCC) agent, enhancing our knowledge about their biologic functions and targets. However there is a significant distinction between the herbal medicine and the herbal production even though both are the plant-based remedies used in the practice. In this article, for the sake of clarity, the effective herbal compounds and herbal composite formulas against HCC are discussed, with emphasizing the basic conceptions of herbal medicine in order to have a better understanding of the prevention and treatment of HCC by herbal active compounds and herbal composite formulas.

Abstract
Nowadays, patients with chronic hepatitis C in all countries are generally treated with interferon (IFN), and more than 50% of patients become HCV-RNA negative following PEG-IFN plus ribavirin therapy, but unfortunately, the IFN therapy is not effective in about 70% of patients with HCV-associated LC. In Japan, HCC actually develops in about 7% of those patients every year. A strategy for preventing HCC development other than IFN therapy is, therefore, urgently needed for those patients.
We reported that the recurrence rate and the development of HCC was more rapid in the high serum ALT level (>80 IU) patients with HCV-associated LC. Sho-saiko-to, Juzen-taiho-to, and stronger-neo minophagen C are herbal medicines used in Japan to treat chronic viral liver diseases, and they work by reducing inflammatory processes and controlling ALT levels. Aggressive reduction therapy for ALT levels in HCV-LC patients could significantly prevent HCC development.

Abstract
The Chinese herbal medicine sho-saiko-to is a mixture of seven herbal components (Bupleurum root, Pinellia tuber, Scutellaria root, Jujube fruit, Ginseng root, Glycyrrhiza root and Ginger rhizome) that is widely administered to patients with chronic hepatitis in Japan. We assessed the effects of sho-saiko-to on the activity of cytochrome P450 (CYP) 1A2, CYP3A and xanthine oxidase (XO) in man. Twenty-six healthy subjects were studied to evaluate their baseline activity of CYP1A2 and XO by the respective urinary metabolic ratios of an 8-h urine sample after an oral 150-mg dose of caffeine and of CYP3A by a urinary excretion ratio of 6β-hydroxycortisol (6β-HC) to free cortisol (FC). Thereafter, the subjects received a twice-daily 2.5-g dose of sho-saiko-to for five days, and underwent the caffeine test on day 1 and day 5. The mean activity of CYP1A2 decreased by 16% on both day 1 and day 5 compared with the baseline (P = 0.001). The mean activity of XO also significantly decreased by 25% on day 1 and 20% on day 5 (P < 0.0001) compared with the baseline value. The activity of CYP3A tended to be lower on day 5 than the baseline (P = 0.146). It is concluded that sho-saiko-to reduces CYP1A2 and XO activity in man.

Abstract
Abstract Objective. To assess retrospectively whether continuously high serum alanine aminotransferase (ALAT) levels (<80 IU) in the first three successive years after the diagnosis of liver cirrhosis (LC) are predictive of a subsequent high incidence of hepatocellular carcinoma (HCC) in patients with Child Stage A hepatitis C virus (HCV)-LC. Material and methods. The study comprised 132 HCV-LC (Child Stage A) patients who had not received interferon therapy but had been treated with anti-inflammatory agents. At the end of a 3-year follow-up after the diagnosis of LC, the patients were subdivided into three groups according to their serum ALAT levels and the subsequent incidence of HCC was assessed. Results. The cumulative incidence of HCC starting from 3 years after the diagnosis of LC in the continuously high ALAT group (annual average over 3 years always > or =80 IU; n=41; Group A) was markedly higher than that in the continuously low ALAT group (always <80 IU; n=48; Group B) (p<0.005) during an observation period of 7.9+/-3.7 years. The incidence of HCC in Group A was 11.8%/year. The odds ratios of developing HCC in Group A and Group C (mixed high and low ALAT levels; n=43) were 5.1-fold and 1.5-fold that of Group B, respectively. A multivariate analysis revealed that the ALAT group was independently associated with HCC development. Conclusions. Continuously high ALAT levels for three successive years following the diagnosis of LC can be predictive of a very high incidence of HCC in Child A HCV-LC patients. Prospective trials using therapeutic approaches aimed at decreasing ALAT levels are necessary in order to confirm a positive impact of ALAT reduction on the incidence of HCC in patients with HCV-LC.

Abstract
BACKGROUND Chemopreventive effect of a selective cyclooxygenase-2 (COX-2) inhibitor JTE-522 on diethylnitrosamine (DEN)-induced hepatocarcinogenesis was evaluated in Wistar rats. METHODS Animals in the control group (G1) were injected with phosphate buffered saline (PBS), those in hepatocellular carcinoma (HCC) group (G2) were injected with DEN with regular foods for 14 weeks, and those in the treatment groups were injected with DEN for 14 weeks fed with JTE-522 for 7 (G3) and 14 weeks (G4), respectively. Proliferation and precancerous lesions were evaluated by expression levels of proliferating cell nuclear antigen (PCNA) and glutathione S-transferase-P (GST-P), respectively by immunohistochemistry and Western blot analysis. Apoptosis and oxidative stress were evaluated by TdT-mediated dUTP-biotin nick-end labeling (TUNEL) and 8-hydroxy-2'-deoxyguanosine (8-OHdG) staining, respectively. RESULTS After 14 weeks of the treatment, HCC was developed in G2, G3, and G4 showing no significant differences in gross appearance and histology of the liver among the three groups. There were no significant differences in the expression levels of PCNA and numbers of TUNEL and 8-OHdG positive cells in the liver among the three groups. However, GST-P positive area was significantly suppressed in G3 and G4 compared to G2. CONCLUSION Our data revealed that JTE-522 had a modest inhibitory effect on hepatocarcinogenesis in rats in a manner independent of induction of apoptosis and inhibition of oxidative stress.

Abstract
BACKGROUND/AIMS Continuous oxidative stress (OS) plays an important role in the progression of chronic liver diseases and hepatocarcinogenesis through telomere shortening in hepatocytes. However, it has not been established how the OS influences the progression of human hepatocellular carcinomas (HCCs). We examined the correlations of OS with telomere length of cancer cells, telomerase activity and other clinicopathological factors in 68 HCCs. METHODS The level of 8-hydroxy-2'-deoxyguanosine (8-OHdG) as a marker of OS was examined immunohistochemically and OS was scored in four grades (0-3). The telomere length of cancer cells was measured by quantitative fluorescence in situ hybridization. Telomerase activity was measured by (i) immunodetection of human telomerase reverse transcriptase (hTERT) and (ii) telomere repeat amplification protocol (TRAP) assay. Telomerase related proteins, phosphatase and tensin homolog deleted on chromosome 10 (PTEN) and Akt, and other clinicopathological factors were also evaluated. RESULTS As the OS grade increased, the average telomere length became significantly shorter in HCCs, especially in the hTERT-negative group. In the state of high-grade OS, hTERT-positive HCC cells showed more proliferative and less apoptotic features compared with hTERT-negative HCC cells. Telomerase activity, as measured by the TRAP assay, was strongly correlated with OS grade in HCCs. Furthermore, a high OS grade was correlated with the downexpression of PTEN and the activation of Akt. CONCLUSIONS Oxidative stress enhanced the malignant potential of HCCs through the activation of telomerase, which raises the possibility of using OS as a marker for assessing the clinical state of HCCs.

Upregulation of interferon-gamma and interleukin-4, Th cell-derived cytokines by So-Shi-Ho-Tang (Sho-Saiko-To) occurs at the level of antigen presenting cells, but not CD4 T cells. JOURNAL OF ETHNOPHARMACOLOGY 2009; 123:6-14. [PMID: 19429332 DOI: 10.1016/j.jep.2009.02.045] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/23/2008] [Revised: 02/07/2009] [Accepted: 02/24/2009] [Indexed: 05/27/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE So-Shi-Ho-Tang (SSHT) or known as Sho-Saiko-To in Japanese and Xiao-Chai-Hu-Tang in Chinese has been used to treat chronic liver disease and other infections, and its hepatoprotective effects have been widely studied. AIM OF THE STUDY We tried to investigate the immunomodulatory effect of SSHT on interferon (IFN)-gamma and interleukin (IL)-4 and their Th1/Th2 transcription factors in vivo and in vitro since these two cytokines are important in determining the type of cell-mediated inflammatory and humoral responses. MATERIALS AND METHODS SSHT was orally given to BALB/c mice for 7 days and then injected with anti-CD3 mAb intravenously. IFN-gamma, IL-4, IL-2 and Th1/Th2-specific transcription factors as well as splenocyte subsets were measured. Splenocytes and CD4 T cells were cultured with anti-CD3 or anti-CD3/anti-CD28 in the presence of SSHT, its constituent herbs and baicalin, and the levels of cytokines and transcription factors were measured by ELISA and western blotting. RESULTS Oral administration of SSHT to mice in response to i.v. anti-CD3 injection enhanced the expression of IFN-gamma, IL-4 and IL-2 in the serum and spleen at the secreted protein and mRNA level. This was accompanied by the upregulation of CD69 and CD4 T cell populations by flow cytometry. The upregulation of IFN-gamma and IL-4 by SSHT did not occur in anti-CD3/anti-CD28 stimulated CD4 T cells in vitro. However, SSHT was capable of producing the cytokines in anti-CD3 stimulated splenocytes even in the absence of CD28, suggesting a role for some soluble factors produced by antigen presenting cells (APC). In support of this, we found that SSHT increased IL-12 and IL-6 in the same cells. STAT4, but not T-bet, was involved in the upregulation of IFN-gamma by SSHT while the increased IL-4 expression was accompanied by a parallel increase in c-Maf but independent of STAT6 and GATA-3. CONCLUSION These data indicate that the upregulation of IFN-gamma and IL-4 by SSHT must occur through some interactions between APC and CD4 T cells. Taken together, the present data provide additional information on some of the immunological mechanisms of SSHT for treatment of liver diseases and infections.

Abstract
Traditional Chinese medicine (TCM) has been used for thousands of years. Most Chinese herbal formulae consist of several herbal components and have been used to treat various diseases. However, the mechanisms of most formulae and the relationship between formulae and their components remain to be elucidated. Here we analyzed the putative mechanism of San-Huang-Xie-Xin-Tang (SHXXT) and defined the relationship between SHXXT and its herbal components by microarray technique. HepG2 cells were treated with SHXXT or its components and the gene expression profiles were analyzed by DNA microarray. Gene set enrichment analysis indicated that SHXXT and its components displayed a unique anti-proliferation pattern via p53 signaling, p53 activated, and DNA damage signaling pathways in HepG2 cells. Network analysis showed that most genes were regulated by one molecule, p53. In addition, hierarchical clustering analysis showed that Rhizoma Coptis shared a similar gene expression profile with SHXXT. These findings may explain why Rhizoma Coptis is the principle herb that exerts the major effect in the herbal formula, SHXXT. Moreover, this is the first report to reveal the relationship between formulae and their herbal components in TCM by microarray and bioinformatics tools.

Abstract
Traditional herbal formulations, such as Juzen-taiho-to (TJ-48), are used extensively in medical practice in Asia even though their mechanism of action remains elusive. This study tested a hypothesis that TJ-48 is protective against hepatocarcinogenesis by impeding Kupffer cell-induced oxidative stress. Forty-eight patients were randomly assigned to receive TJ-48 (n = 10), or no supplementation (n = 38) for up to 6 years after surgical treatment for hepatocellular carcinoma (HCC). In addition, to investigate the mechanism of protective action of TJ-48, diethylnitrosamine-containing water was administered for 22 weeks to male mice that were fed regular chow or TJ-48-containing diet. Liver tumor incidence, cell proliferation, number of 8-hydroxy-2'-deoxyguanosine- or F4/80-positive cells, and cytokine expression were evaluated. Although most of the patients experienced recurrence of HCC, a significantly longer intrahepatic recurrence-free survival was observed in the TJ-48 group. In mice, TJ-48 inhibited the development of liver tumors, reduced oxidative DNA damage, inflammatory cell infiltration and cytokine expression. Administration of TJ-48 improves intrahepatic recurrence-free survival after surgical treatment of hepatocellular carcinoma. On the basis of animal experiments, we reason that the protective mechanism of TJ-48 involves inhibition of Kupffer cells. This leads to lower levels of pro-inflammatory cytokines and oxidants in liver which may slow down the process of hepatocarcinogenesis and improves hepatic recurrence-free survival in patients with HCC.

Abstract
Data on the efficacy of herbal compounds are often burdened by the lack of appropriate controls or a limited statistical power. Treatments to prevent the progression of non alcoholic fatty liver disease (NAFLD) to steatohepatitis (NASH) remain unsatisfactory. A total of 56 rabbits were arrayed into 7 groups fed with standard rabbit chow (SRC), SRC with 1% cholesterol, or each of the five experimental treatments (Kampo formulas 1% keishibukuryogan [KBG], 1% orengedokuto [OGT], and 1% shosaikoto [SST]; vitamin E [VE]; or pioglitazone [PG]) in a 1% cholesterol SRC. We analyzed changes after 12 weeks in plasma and liver lipid profiles, glucose metabolism, adipocytokines, oxidative stress, and liver fibrosis. Data demonstrated that all five treatments were associated with significant amelioration of lipid profiles, oxidative stress, and liver fibrosis compared to no supplementation. KBG was superior to VE and PG in the reduction of liver total cholesterol ( P < 0.01) and lipid peroxidase levels ( P < 0.05), urinary 8-hydroxy-2′-deoxyguanosine ( P < 0.05), hepatic α-smooth muscle actin positive areas ( P < 0.01) and activated stellate cells ( P < 0.01). In conclusion, there was a statistically significant benefit of Kampo formulas (KBG in particular) on a dietary model of NAFLD/NASH. Future studies need to be directed at the mechanisms in the treatment of NASH.

Abstract
Quercetin exhibits a potent anticarcinogenic activity. However, ingested quercetin circulates as the glucuronide/sulfate conjugates, which are less active compared to the aglycone in healthy individuals. This study aimed to develop further understandings of the cancer-preventing mechanism with dietary quercetin. According to a two-stage hepatocarcinogenesis model with N-diethylnitrosamine (DEN) and phenobarbital (PB), preneoplasms were induced specifically in the liver of Fisher 344 rats. In the liver, glutathione S-transferase placental form (GST-P) positive foci were produced 14 weeks later. beta-Glucuronidase activity increased significantly in the liver by 1.2-fold in the DEN/PB group compared to the activity in a saline group. In the kidney, thymus, lung, heart, and plasma, the activities were similar between both groups. When quercetin was dosed intragastrically 15 min before sacrifice, the aglycone level of quercetin in liver was significantly 1.9-fold higher in the DEN/PB group than in the saline group. On the other hand, quercetin was dosed to rats 3 times a week for 14 weeks. The treatment kept the aglycone level of quercetin at a significantly higher level and tended to suppress the formation of GST-P positive foci. The increase in beta-glucuronidase activity with carcinogenesis induction became insignificant following the frequent doses of quercetin. It was considered that quercetin aglycone played a preventative role and, thus, the conjugates were converted to the active aglycone by beta-glucuronidase that was induced by the generation of preneoplasms.

Abstract
To search for an effective antiviral agent, this study tested the hypothesis that sho-saiko-to (Xiao-Chai-Hu-Tang) and crude saikosaponins possess the activity directly against HBV and could affect the expressions of viral antigens, HBeAg and HBsAg, in HepG(2) 2.2.15 cell model. The viral amount and viral antigens in the suspension were estimated by quantitative real time PCR and enzyme-linked immunosorbent assay (ELISA), respectively. The results showed that sho-saiko-to could inhibit the production of HBV (p < 0.0001), 20 microg/ml sho-saiko-to was efficacious at day-3 of treatment and 10 microg/ml at day-6. The calculated IC(50) and CC(50) of sho-saiko-to were 55.76 microg/ml and 372 microg/ml, respectively, with a selectivity index of 6.67. Crude saponin of B. chinense could also inhibit the replication of HBV (p < 0.0001). Owing to the anti-neoplastic activity of sho-saiko-to and saikosaponin, their calculated CC(50) and selectivity index might be under-estimated. Sho-saiko-to also decreased the expression of HBeAg with the minimal effective concentration of 20 microg/ml. Sho-saiko-to contained too little saikosaponin. Therefore, the anti-HBV activity of sho-saiko-to might not be mediated by saikosaponin. Sho-saiko-to could be supplementary to nucleotide analogues to minimize the recurrence of viremia after its discontinuation.

Abstract
BACKGROUND AND AIM Oxidative DNA damage occurs as an early event in hepatitis C virus (HCV) infection and is an indication of the potential for carcinogenesis. The aim of this study was to test a novel antioxidant/immunomodulator in patients with HCV-related cirrhosis. METHODS The study group consisted of 50 patients with HCV-related cirrhosis with transaminase values less than twofold increased (alanine aminotransferase [ALT] < 80 IU/L). Patients underwent a standardized food-vitamin composition assessment and were assessed for dietary intake, nutritional status and iron level. Patients were randomly allocated into two groups and then given either alpha-tocopherol 900 IU/day or 9 g/day of a fermented papaya preparation (FPP, Immun-Age, Osato Research Institute, Gifu, Japan) at bedtime for 6 months. Ten healthy subjects served as controls. Patients were checked monthly for: routine tests, redox status (reduced glutathione, glutathione peroxidase, oxidized glutathione, malondialdehyde), plasma alpha-tocopherol, 8-hydroxy-deoxy-guanidine (8-OHdG) level in circulating leukocyte DNA and serum levels of cytokines. RESULTS Patients with cirrhosis showed a significant imbalance of redox status (low antioxidants/high oxidative stress markers) (P < 0.005 vs controls). Neither treatment regimen affected transaminases as a whole. However, vitamin E supplementation almost normalized ALT only in the limited vitamin-E-deficient subgroup. A significant improvement of redox status was obtained by both regimens. However, only FPP significantly decreased 8-OHdG and the improvement of cytokine balance with FPP was significantly better than with vitamin E treatment (P < 0.05). CONCLUSIONS Although the present data seem to suggest a potential supportive role of antioxidants/immunomodulators as FPP in HCV patients, more studies are needed to substantiate their effect on the natural history of the disease.

Abstract
Herbal drugs have become increasingly popular and their use is widespread. Licensing regulations and pharmacovigilance regarding herbal products are still incomplete and clearcut proof of their efficacy in liver diseases is sparse. Nevertheless, a number of herbals show promising activity including silymarin for antifibrotic treatment, phyllantus amarus in chronic hepatitis B, glycyrrhizin to treat chronic viral hepatitis, and a number of herbal combinations from China and Japan that deserve testing in appropriate studies. Apart from therapeutic properties, reports are accumulating about liver injury after the intake of herbals, including those advertised for liver diseases. Acute and/or chronic liver damage occurred after ingestion of some Chinese herbs, herbals that contain pyrrolizidine alkaloids, germander, greater celandine, kava, atractylis gummifera, callilepsis laureola, senna alkaloids, chaparral and many others. Since the evidence supporting the use of botanicals to treat chronic liver diseases is insufficient and only few of them are well standardised and free of potential serious side effects, most of these medications are not recommended outside clinical trials. Particularly with regard to the latter, adequately powered randomised-controlled clinical trials with well-selected end points are needed to assess the role of herbal therapy for liver diseases.

Abstract
The prooxidant and apoptosis-inducing effects of Sho-saiko-to, a traditional Sino-Japanese herbal medicine and its active ingredients were analyzed. Among the components of Sho-saiko-to, wogon, the extract of Scutellaria and licorice root extract induced apoptosis of HL60 cells and increased the intracellular levels of reactive oxygen species. Lower concentrations (5 to 20 muM) of baicalein, the principal flavonoid in the Scutellaria root extract, showed induction of cell apoptosis and elevated the intracellular reactive oxygen species. However, the increase in the concentrations of baicalein rather inhibited the induction of apoptosis and the elevated levels of reactive oxygen species in cells. Induction of baicalein-mediated apoptosis was inhibited by addition of Tempol, the scavenger of reactive oxygen species. Glycyrrhetinic acid, an ingredient of licorice root extract, also induced apoptosis followed by increase in the intracellular reactive oxygen species. The effect of Sho-saiko-to on cell differentiation can be explained by the action of two ingredients, baicalein and glycyrrhetinic acid, which cause apoptosis and increase in reactive oxygen species in cells.

Abstract
Kampo (Japanese traditional herbal) medicines have been produced by combining multiple crude drugs, almost all of plant origin but with some of animal or mineral origin, and contain a great many substances. Their effect is a combination of the various interactions of the constituent substances, whether they are enhancing, synergistic or suppressive. Kampo medicine has an overall effect that is different from the combined effects of individual crude drugs, and several side effects such as anorexia, slight fever and nausea have been reported in the treatment of certain disorders and disease states with Kampo medicines. Among 210 medical formulations used in Japan, some relevant information on the clinical uses, pharmacology and toxicology of six manufactured Kampo medical formulations, Shosaikoto, Daisaikoto, Saikokeishito, Hochuekkito, Saibokuto and Saireito, containing Bupleurum root are reviewed. Studies of some potential interactions between Kampo medicine and western drugs are also considered.

Abstract
Diethylnitrosamine (DEN) is a well-known carcinogenic substance that requires microsomal activation before it can react with DNA to cause mutations and cancer. The aim of this study was to use in vivo spin trapping and spin probe techniques to investigate whether free radicals are generated in rat liver tissue during DEN activation. We used alpha-phenyl-n-tert-butylnitrone (PBN) as the spin trapping agent, which was delivered through an intraperitoneal injection before DEN administration. One hour after DEN administration, multicomponent PBN adducts in the bile were detected, and the intensities were diminished by the cytochrome P450 inhibitor SKF-525A. A computer simulation of the ESR signals revealed the presence of a lipid-derived radical. Using the in vivo spin probe/ESR technique, the signal decay rate of methoxycarbonyl-PROXYL was significantly increased in the DEN-treated group compared with the rate in the vehicle group. The enhanced signal decay rate was restored with PBN and/or SKF-525A pretreatment. These results suggested that lipid-derived free radicals were generated in the liver within 1 h after DEN administration.

Inhibitory effects of herbal drugs on the growth of human ovarian cancer cell lines through the induction of apoptosis. Gynecol Oncol 2005; 97:405-9. [PMID: 15863137 DOI: 10.1016/j.ygyno.2004.12.063] [Citation(s) in RCA: 26] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2004] [Revised: 12/27/2004] [Accepted: 12/30/2004] [Indexed: 10/25/2022]
Abstract
OBJECTIVE In order to develop and search for more effective and safe treatments for early and advanced stages of ovarian cancer, we examined the direct effects of four extracts of Chinese herbal drugs on ovarian cancer cells in vitro. METHODS The growth inhibition of four herbal drugs on a total of six cell lines of human ovarian cancer cells was determined by a Cell Counting Kit-8 by counting viable cells. Apoptotic cells induced by herbal drugs were detected by using MEBCYTO Apoptosis Kit. All experiments were performed in triplicate. The significance of the difference was analyzed with a two-sided Student's t test. A P value less than 0.05 was accepted as statistically significant. RESULTS The MN, A2780, and KF cell lines exhibited significant growth inhibition in the presence of Sho-saiko-to concentrations of 150 microg/ml, 300 microg/ml, and 500 microg/ml, respectively, and at the concentration of 1000 microg/ml, Sho-saiko-to demonstrated a significant apoptotic induction effect on all six kinds of ovarian cancer cell lines. This concentration is the same as the blood concentration attained when 7.5 g of Sho-saiko-to per day is orally administered and all absorbed. CONCLUSIONS Sho-saiko-to exhibited significant growth inhibition of ovarian cancer cell lines, and the mechanisms of the inhibitory effects can be attributed, in part, to apoptosis induced by Sho-saiko-to.

Abstract
The eventual chemopreventive effect of squalene (SQ), a triterpene present in olive oil, was evaluated when administered to Wistar rats during a period comprising the initiation and selection/promotion of the "resistant hepatocyte" (RH) model of hepatocarcinogenesis. During 8 consecutive wk, animals received by gavage SQ (100 or 150 mg/100 g body weight) dissolved in corn oil (CO) daily. Animals treated with only CO and submitted to the RH model were used as controls. Treatments with SQ did not result in inhibition of macroscopically visible hepatocyte nodules (P > 0.05) or of hepatic placental glutathione S-transferase- positive preneoplastic lesions (PNL; P > 0.05). Hepatic cell proliferation and apoptosis indexes were not different (P > 0.05) among the different experimental groups, both regarding PNL and surrounding normal tissue areas. There were no significant differences (P > 0.05) among comets presented by rats treated with the two SQ doses or with CO. On the other hand, SQ increased total plasma cholesterol levels when administered at both doses (P < 0.05). This indicates that the isoprenoid was absorbed. Thus, SQ did not present chemopreventive activity during hepatocarcinogenesis and had a hypercholesterolemic effect, suggesting caution when considering its use in chemoprevention of cancer.

Abstract
We developed hepatitis C virus (HCV) core-E1-E2 and HCV core transgenic mice on a common genetic background to assess the contribution of HCV structural proteins to hepatocarcinogenesis. Eight-week-old core-E1-E2, core, and nontransgenic mice inbred on the FVBxC57Bl/6 background were treated with diethylnitrosamine (DEN) and sacrificed at 32 weeks old. Proliferation and apoptosis were assessed by immunohistochemistry. The effect of viral proteins on apoptosis was evaluated in HepG2 cells in which apoptosis was induced by anti-Fas antibody. HCCs were identified at 32 weeks in the majority of DEN-treated mice from all three groups. The mean size of HCCs was significantly larger in core-E1-E2 transgenic (4.63 +/- 1.48 mm), compared with core transgenic (0.78 +/- 0.26 mm, P = .01), and nontransgenic (1.0 +/- 0.19 mm, P = .002) mice. While there were no differences in proliferation, the apoptotic index in core-E1-E2 transgenic HCCs was significantly lower than those found in core and non-transgenic HCCs. Core-E1-E2 transfected HepG2 cells demonstrated a significantly lower apoptotic index (0.35 +/- 0.11) compared with that of core transfected cells (0.74 +/- 0.07, P = .0103). Analysis of a Fas-induced apoptosis model in HCV transgenic mice confirmed that core-E1-E2 transgenic liver underwent significantly less apoptosis than transgenic tissue expressing core only. In conclusion, HCV core-E1-E2 transgenic mice develop significantly larger tumors than transgenic mice expressing core alone or nontransgenic mice. The accelerated tumor phenotype is attributable to suppression of apoptosis rather than enhanced proliferation. These data implicate HCV E1 and/or E2 in conjunction with core as antiapoptotic, tumor accelerator proteins.

Abstract
Sho-saiko-to (SST), a Chinese/Japanese traditional herbal medicine, has been widely used to treat chronic hepatitis in Japan, and the immunomodulatory properties of SST are likely to mediate its beneficial effect. In the present study, we examined the effects of SST and its various ingredients on the count and proliferation of T-cell subsets in cultured splenocytes and hepatic mononuclear cells. SST, wogonin-7-O-glucuronoside (a major SST ingredient), and wogonin (an intestinal metabolite of wogonin-7-O-glucuronoside) increased CD4/CD8 ratio via a decrease of CD8+ T-cell counts with no effect on CD4+ T-cell counts. Flow cytometric analyses of viability, proliferation, and cell cycle revealed that wogonin suppressed CD8+ T-cell proliferation without inducing cell death. SST and wogonin administered to mice increased the CD4/CD8 ratio in hepatic mononuclear cells but not in splenocytes. These findings suggest that SST may modulate the CD4/CD8 ratio via the selective inhibition of CD8+ T-cell proliferation by the SST ingredient wogonin-7-O-glucuronoside or its metabolite wogonin.

Abstract
Apigenin (4',5,7-trihydroxyflavone), a flavone subclass of flavonoid widely distributed in many herbs, fruits, and vegetables is a substantial component of the human diet and has been shown to possess a variety of biological activities including tumor growth inhibition and chemoprevention. Recent studies in several biological systems have shown that apigenin induces tumor growth inhibition, cell cycle arrest, and apoptosis. Free radical-induced degradation of polyunsaturated fatty acid results in electrophilic products and causes severe oxidative stress. Oxidative stress induced by free radicals, nonoxidizing species, electrophiles, and associated DNA damages have been frequently coupled with carcinogenesis. In the present study, the protective role of apigenin was examined against the oxidative stress caused by N-nitrosodiethylamine (NDEA) and phenobarbital (PB) in Wistar albino rats. Oxidative stress was measured in terms of lipid peroxidation (LPO) and protein carbonyl formation. Oxidative stress-induced DNA damage was measured by single cell gel electrophoresis (comet assay). Apigenin exhibited its antioxidant defense against NDEA-induced oxidative stress. We have observed minimal levels of LPO and DNA damage in apigenin-treated hepatoma bearing animals. Based on the results, we suggest that apigenin may be developed as a promising chemotherapeutic agent against the development of chemical carcinogenesis.

Abstract
AIM: To explore the effects of drug-contained serum of different herb compatibilities of Xiao Chaihu Tang (XCHT) on a hepatocytic injury model.
METHODS: The hepatocytic injury model was induced by CCl4 (10 mmoL/L-1), The injured hepatocytes were incubated with CCl4 and drug-contained serum of different herb compatibilities of XCHT for 24 h. The cells were observed under microscope with Giemsa and TUNEL staining. The apoptosis rate was measured by flow cytometry.
RESULTS: Different herb compatibilities of XCHT could improve the hepatocytic proliferation rate, which was injured by CCl4 significantly (1.22±1.00, 1.11±0.09, 1.12±0.18, 1.10±0.08, vs 0.78±0.07, P < 0.01), decrease ALT concentration in cell culture solution (948±162,748±278, 1 081±226, 1 148±163, vs 2 110±377, P < 0.01). There were obvious necrosis and apoptosis in the model group cell observed under the convert microscope and Giemsa and TUNEL staining. CCl4 induced the apoptosis of cells in model group (2.9 467±1.0 007 vs 16.3 175±4.5 358, P < 0.01). The original recipe of XCHT group (G), bupleurum root-scutellaria root group (A) resisted the apoptosis induced by CCl4 (4.2 117±2.3 733, 6.4 800±2.4 052, 5.6 200±2.0 573, 4.6 440±0.8 825, vs 16.3 175±4.5 358, P < 0.01).
CONCLUSION: Drug-contained serum of different herb compatibilities of XCHT can protect hepatocytic injury induced by CCl4in vitro. There are obvious apoptosis and necrosis when CCl4 injures the hepatocyte. The different herb compatibilities of XCHT are of the effects of resisting hepatocytic apoptosis induced by CCl4.

Abstract
Although attention has focused on the chemopreventive action of retinoic acid (RA) in hepatocarcinogenesis, the functional role of RA in the liver has yet to be clarified. To explore the role of RA in the liver, we developed transgenic mice expressing RA receptor (RAR) alpha- dominant negative form in hepatocytes using albumin promoter and enhancer. At 4 months of age, the RAR alpha- dominant negative form transgenic mice developed microvesicular steatosis and spotty focal necrosis. Mitochondrial beta-oxidation activity of fatty acids and expression of its related enzymes, including VLCAD, LCAD, and HCD, were down-regulated; on the other hand, peroxisomal beta-oxidation and its related enzymes, including AOX and BFE, were up-regulated. Expression of cytochrome p4504a10, cytochrome p4504a12, and cytochrome p4504a14 was increased, suggesting that omega-oxidation of fatty acids in microsomes was accelerated. In addition, formation of H2O2 and 8-hydroxy-2'-deoxyguanosine was increased. After 12 months of age, these mice developed hepatocellular carcinoma and adenoma of the liver. The incidence of tumor formation increased with age. Expression of beta-catenin and cyclin D1 was enhanced and the TCF-4/beta-catenin complex was increased, whereas the RAR alpha/ beta-catenin complex was decreased. Feeding on a high-RA diet reversed histological and biochemical abnormalities and inhibited the occurrence of liver tumors. These results suggest that hepatic loss of RA function leads to the development of steatohepatitis and liver tumors. In conclusion, RA plays an important role in preventing hepatocarcinogenesis in association with fatty acid metabolism and Wnt signaling.

Abstract
OBJECTIVES We have previously reported that an antioxidant, auraptene (AUR), isolated from citrus fruit effectively inhibits chemically induced carcinogenesis in digestive tracts, such as the oral cavity, esophagus and large bowel. In this study, we investigated the modifying effects of dietary supplementation with AUR on N,N-diethylnitrosamine (DEN)-initiated hepatocarcinogenesis in male F344 rats in two different experiments to determine whether the compound exerts a cancer-chemopreventive action in other organs. METHODS In the first experiment, animals were fed diets containing AUR at dose levels of 100 and 500 ppm for 7 weeks 1 week before, during, and 1 week after the start of liver carcinogenesis induced by DEN (40 ppm in drinking water for 5 weeks) to predict the modulatory effect on hepatocarcinogenesis. After 7 weeks, the numbers of hepatocellular enzyme-altered foci (EAF; cm(2)) which stained positive for the placental form of glutathione S-transferase (GST-P) and transforming growth factor (TGF)-alpha were determined on immunohistochemically stained sections. In the second experiment conducted to confirm the findings, animals subjected to DEN treatment were fed AUR-containing diets (100 and 500 ppm) during either the initiation stage ('initiation' feeding for 7 weeks) or post-initiation phase ('post-initiation' feeding for 25 weeks) of DEN-induced hepatocarcinogenesis. RESULTS In the first experiment, feeding with AUR at both doses during DEN exposure decreased the mean numbers of GST-P-positive and TGF-alpha-positive EAF/cm(2), and the reduction in the number of TGF-alpha-positive EAF by feeding 500 ppm AUR was statistically significant (p < 0.005). In the second experiment, the 'initiation' feeding with 500 ppm AUR significantly inhibited the incidence (33 vs. 83%, p = 0.000511) and multiplicity (0.67 +/- 1.09 vs. 1.96 +/- 1.85, p < 0.005) of liver cell carcinoma. Also, the 'post-initiation' feeding with AUR at both doses significantly reduced the development of hepatocellular carcinoma (100 ppm: incidence, 15%, p = 0.000006; multiplicity: 0.25 +/- 0.64, p < 0.001; 500 ppm: incidence, 11%, p = 0.000002; multiplicity, 0.26 +/- 0.81, p < 0.001). In addition, AUR feeding reduced cell proliferation and the apoptotic index in liver cell neoplasms. CONCLUSIONS The results suggest that the citrus antioxidant AUR is a potential chemopreventive agent against DEN-induced hepatocarcinogenesis in rats.

Abstract
Accumulation of genetic alterations in hepatocarcinogenesis is closely associated with chronic inflammatory liver disease. 8-oxo-2'-deoxyguanosine (8-oxo-dG), the major promutagenic DNA adduct caused by reactive oxygen species (ROS), leads to G:C --> T:A transversions. These lesions can be enzymatically repaired mainly by human MutT homolog 1 (hMTH1), human 8-oxo-guanine DNA glycosylase (hOGG1) and human MutY homolog (hMYH). The aim of this study was to evaluate the extent of oxidative damage and its dependence on the cellular antioxidative capacity and the expression of specific DNA repair enzymes in tumor (tu) and corresponding adjacent nontumor (ntu) liver tissue of 23 patients with histologically confirmed hepatocellular carcinoma. 8-oxo-dG levels, as detected by high-pressure liquid chromatography with electrochemical detection, were significantly (P =.003) elevated in ntu tissue (median, 129 fmol/microg DNA) as compared to tu tissue (median, 52 fmol/microg DNA), and were closely associated with inflammatory infiltration. In ntu tissue, the hepatic iron concentration and malondialdehyde levels were significantly (P =.001) higher as compared to tu tissue. Glutathione content, glutathione peroxidase activity and manganese superoxide dismutase messenger RNA (mRNA) expression did not show statistical differences between ntu and tu tissue. Real-time reverse transcription polymerase chain reaction revealed in tu tissue significantly (P =.014) higher hMTH1 mRNA expression compared to ntu tissue. In contrast, hMYH mRNA expression was significantly (P <.05) higher in ntu tissue. No difference in hOGG1 mRNA expression was seen between tu and ntu. In conclusion, these data suggest that ROS generated by chronic inflammation contribute to human hepatocarcinogenesis. The role of DNA repair enzymes appears to be of reactive rather than causative manner.

Abstract
As the consumption of herbal remedies has increased, the opportunity that such herbal medicines are co-administered with other drugs has also risen gradually and we are, therefore, very much concerned about herb-drug interactions. We examined the effects of pre-administration of Kampo medicines (Sho-saiko-to, Saiko-keishi-to, Shigyaku-san and Dai-saiko-to) on the pentobarbital-induced sleeping time in mice and rats, to clarify the possibility that they could affect the drug-metabolizing enzymes. The administration of Sho-saiko-to and Saiko-keishi-to for 4 weeks significantly shortened the pentobarbital-induced sleeping time in mice and the administration of Sho-saiko-to for 2 weeks significantly reduced the sleeping time in rats. Furthermore, we tried to identify the molecular species of rat cytochrome P450s (CYPs) affected by Sho-saiko-to and Saiko-keishi-to by competitive RT-PCR. The oral administration of Sho-saiko-to for 2 weeks upregulated the mRNA expression of CYP2B, CYP3A1, CYP2E1 and CYP4A1 in rats. The treatment with Saiko-keishi-to for 2 weeks also up-regulated the mRNA expression of CYP2B, CYP3A1 and CYP4A1. Sho-saiko-to and Saiko-keishi-to may potentially influence the drug-metabolizing enzymes in man, and would thus require much attention when used in the clinical situation.

Abstract
The antitumor effects of melatonin on diethylnitrosamine (DEN)-initiated and/or phenobarbital (PB)-promoted hepatocarcinogenesis were investigated in male F344 rats. Five-week-old male F344 rats were divided into eight groups. Rats in groups 1-5 were given DEN (100 mg/kg body weight, i.p.) once a week for 3 wk, whereas those in groups 6-8 received vehicle treatment. Groups 1-3 and 7 were given 500 ppm PB in drinking water for 20 wk after DEN or vehicle treatment. Group 2 was given 400 ppm melatonin-containing diet during the initiation phase. Groups 3 and 5 were fed melatonin-containing diet for 20 wk, starting 1 wk after the last dosing of DEN. Group 6 was given melatonin-containing diet alone throughout the experiment (24 wk). Group 8 was treated with vehicle alone. Liver neoplasms were recognized only in DEN-treated groups. The incidences and multiplicities of hepatocellular adenoma and hepatocellular carcinoma (HCC) in group 3 were significantly smaller when compared with group 1 (P < 0.001 or P < 0.002). The average and unit areas of glutathione S-transferase placental form (GST-P)-positive foci of groups 2 and 3 were significantly smaller than those of group 1 (P < 0.001 or P < 0.01). The density and average area of these preneoplastic lesions of group 5 were also smaller than those of group 4 (P < 0.001 or P < 0.005). In addition, the ornithine decarboxylase activity in nonneoplastic liver tissue was reduced by melatonin treatment in both the initiation and postinitiation phases. These results suggest that melatonin has an antitumor-promoting ability in DEN-initiated and PB-promoted hepatocarcinogenesis in rats.
