Mukherjee PK, Efferth T, Das B, Kar A, Ghosh S, Singha S, Debnath P, Sharma N, Bhardwaj PK, Haldar PK. Role of medicinal plants in inhibiting SARS-CoV-2 and in the management of post-COVID-19 complications. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 98:153930. [PMID: 35114450 PMCID: PMC8730822 DOI: 10.1016/j.phymed.2022.153930] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/03/2021] [Revised: 12/30/2021] [Accepted: 01/03/2022] [Indexed: 05/07/2023]
Abstract
BACKGROUND The worldwide corona virus disease outbreak, generally known as COVID-19 pandemic outbreak resulted in a major health crisis globally. The morbidity and transmission modality of COVID-19 appear more severe and uncontrollable. The respiratory failure and following cardiovascular complications are the main pathophysiology of this deadly disease. Several therapeutic strategies are put forward for the development of safe and effective treatment against SARS-CoV-2 virus from the pharmacological view point but till date there are no specific treatment regimen developed for this viral infection. PURPOSE The present review emphasizes the role of herbs and herbs-derived secondary metabolites in inhibiting SARS-CoV-2 virus and also for the management of post-COVID-19 related complications. This approach will foster and ensure the safeguards of using medicinal plant resources to support the healthcare system. Plant-derived phytochemicals have already been reported to prevent the viral infection and to overcome the post-COVID complications like parkinsonism, kidney and heart failure, liver and lungs injury and mental problems. In this review, we explored mechanistic approaches of herbal medicines and their phytocomponenets as antiviral and post-COVID complications by modulating the immunological and inflammatory states. STUDY DESIGN Studies related to diagnosis and treatment guidelines issued for COVID-19 by different traditional system of medicine were included. The information was gathered from pharmacological or non-pharmacological interventions approaches. The gathered information sorted based on therapeutic application of herbs and their components against SARSCoV-2 and COVID-19 related complications. METHODS A systemic search of published literature was conducted from 2003 to 2021 using different literature database like Google Scholar, PubMed, Science Direct, Scopus and Web of Science to emphasize relevant articles on medicinal plants against SARS-CoV-2 viral infection and Post-COVID related complications. RESULTS Collected published literature from 2003 onwards yielded with total 625 articles, from more than 18 countries. Among these 625 articles, more than 95 medicinal plants and 25 active phytomolecules belong to 48 plant families. Reports on the therapeutic activity of the medicinal plants belong to the Lamiaceae family (11 reports), which was found to be maximum reported from 4 different countries including India, China, Australia, and Morocco. Other reports on the medicinal plant of Asteraceae (7 reports), Fabaceae (8 reports), Piperaceae (3 reports), Zingiberaceae (3 reports), Ranunculaceae (3 reports), Meliaceae (4 reports) were found, which can be explored for the development of safe and efficacious products targeting COVID-19. CONCLUSION Keeping in mind that the natural alternatives are in the priority for the management and prevention of the COVID-19, the present review may help to develop an alternative approach for the management of COVID-19 viral infection and post-COVID complications from a mechanistic point of view.

The effectiveness of traditional Japanese medicine Goshajinkigan in irradiation-induced aspermatogenesis in mice. BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 19:362. [PMID: 31829240 PMCID: PMC6907346 DOI: 10.1186/s12906-019-2786-z] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/27/2018] [Accepted: 12/02/2019] [Indexed: 12/23/2022]
Abstract
Background Infertility and gonadal dysfunction are well known side-effects by cancer treatment in males. In particularly, chemotherapy and radiotherapy induced testicular damage, resulting in prolonged azoospermia. However, information regarding therapeutics to treat spermatogenesis disturbance after cancer treatment is scarce. Recently, we demonstrated that Goshajinkigan, a traditional Japanese medicine, can completely rescue severe busulfan-induced aspermatogenesis in mice. In this study, we aimed to detect the effects of Goshajinkigan on aspermatogenesis after irradiation. Methods This is animal research about the effects of traditional Japanese medicine on infertility after cancer treatment. C57BL/6 J male mice received total body irradiation (TBI: a single dose of 6Gy) at 4 weeks of age and after 60 days were reared a Goshajinkigan (TJ107)-containing or TJ107-free control diet from day 60 to day 120. Then, two untreated females were mated with a single male from each experimental group. On day 60, 120 and 150, respectively, the sets of testes and epididymis of the mice in each group after deep anesthetization were removed for histological and cytological examinations. Results Histological and histopathological data showed that 6Gy TBI treatment decreased the fertility rate (4/10) in the control diet group; in contrast, in the TJ107-diet group, the fertility rate was 10/10 (p < 0.05 vs. 6Gy group). Supplementation with TJ107 was found to rescue the disrupted inter-Sertoli tight junctions via the normalization of claudin11, occludin, and ZO-1 expression and reduce serum anti-germ cell autoantibodies. Conclusions These findings show the therapeutic effect on TBI-induced aspermatogenesis and the recovering disrupted gonadal functions by supplementation with TJ107.

Abstract
OBJECTIVE This study evaluated the effect of cinnamon on disease activity, serum levels of some inflammatory markers, and cardiovascular risk factors in women with rheumatoid arthritis (RA). METHODS In this randomized double-blind clinical trial, 36 women with RA were randomly divided to 2 groups, receiving 4 capsules of either 500 mg cinnamon powder or placebo daily for 8 weeks. Fasting blood sugar (FBS), lipid profile, liver enzymes, serum levels of C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), erythrocyte sedimentation rate (ESR), blood pressure, and clinical symptoms were determined at baseline and end of the week 8. RESULTS At the end of the study, there was a significant decrease of serum levels of CRP (p < 0.001) and TNF-α (p < 0.001) in the cinnamon group as compared to the placebo group. Diastolic blood pressure was also significantly lower in the intervention group compared with the control group (p = 0.017). Compared with placebo, cinnamon intake significantly reduced the Disease Activity Score (DAS-28) (p < 0.001), Visual Analogue Scale (VAS) (p < 0.001), and tender (TJC) (p < 0.001) and swollen joints (SJC) (p < 0.001) counts. No significant changes were observed for FBS, lipid profile, liver enzymes, or ESR. CONCLUSION Cinnamon supplementation can be a safe and potential adjunct treatment to improve inflammation and clinical symptoms in patients with RA.

Abstract
OBJECTIVE To investigate the anti-arthritic and anti-inflammatory effects of the mixture of three herbal agents, Cinnamon Cortex, Persica Semen, and Natril Sulfas (CPN), the major ingredients of Taoren Chengqi Decoction (). METHODS Collagen-induced arthritis (CIA) was induced by immunization with bovine type II collagen on day 1 and 21. DBA/1J mice were orally administered the water extract of CPN (100 and 500 mg/kg) and indomethacin (1 mg/kg) or vehicle (water) 3 times per week for 6 weeks. Arthritic symptoms were recorded on day 29, 31, 33, 36 and 38. On sacrififi ce, serum was obtained for inflammatory markers and anti-collagen antibodies as well as arthritic joints were obtained for histologic analysis. For the evaluation of in vitro anti-inflammatory mechanism of CPN, peritoneal macrophages were isolated from thioglycollate injected C57BL/6 mice and stimulated with lipopolysaccharides (LPS) for 15 min in the presence of CPN extract. Levels of inhibitor of NF-κB α isoform (IκBα), phospho-p38, phospho-C-Jun N-terminal kinases (JNK) and phospho-extracellular signal-regulated kinase 1/2 (ERK1/2) were detected by Western blot. RESULTS Compared with mice in CIA group, oral administration of CPN signififi cantly reduced the clinical scores (P<0.05), histological analysis revealed the protective effect of CPN on inflamed joints. Serum levels of the pro-inflammatory markers tumor necrosis factor-α, interleukin-6 and prostaglandin E2, but not anti-collagen antibodies, were significantly reduced (P<0.05). CPN did not affect the activation of p38, JNK and ERK1/2 but inhibited LPS-induced IκBα degradation, a required event prior to the translocation of NF-κB to the nucleus. CONCLUSIONS The ameliorating effect of CPN on arthritis progression seems to be mediated by its anti-inflammatory effect, without affecting antibody response. As a supplementary agent, CPN could be benefifi cial for treatment of CIA.

Molecules 2016; 21:E1253. [PMID: 27657030 PMCID: PMC6274362 DOI: 10.3390/molecules21091253] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2016] [Revised: 09/10/2016] [Accepted: 09/12/2016] [Indexed: 12/13/2022] Open
Abstract
Oxaliplatin, a chemotherapy drug, induces acute peripheral neuropathy characterized by cold allodynia, spinal glial activation and increased levels of pro-inflammatory cytokines. Herein, we determined whether Cinnamomi Cortex (C. Cortex), a widely used medicinal herb in East Asia for cold-related diseases, could attenuate oxaliplatin-induced cold allodynia in rats and the mechanisms involved. A single oxaliplatin injection (6 mg/kg, i.p.) induced significant cold allodynia signs based on tail immersion tests using cold water (4 °C). Daily oral administration of water extract of C. Cortex (WECC) (100, 200, and 400 mg/kg) for five consecutive days following an oxaliplatin injection dose-dependently alleviated cold allodynia with only a slight difference in efficacies between the middle dose at 200 mg/kg and the highest dose at 400 mg/kg. WECC at 200 mg/kg significantly suppressed the activation of astrocytes and microglia and decreased the expression levels of IL-1β and TNF in the spinal cord after injection with oxaliplatin. Furthermore, oral administration of coumarin (10 mg/kg), a major phytocompound of C. Cortex, markedly reduced cold allodynia. These results indicate that C. Cortex has a potent anti-allodynic effect in oxaliplatin-injected rats through inhibiting spinal glial cells and pro-inflammatory cytokines. We also suggest that coumarin might play a role in the anti-allodynic effect of C. Cortex.

Abstract
Background Alternative medicine is noted for its clinical effect and minimal invasiveness in the treatment of neuropathic pain. Go-sha-jinki-Gan, a traditional Japanese herbal medicine, has been used for meralgia and numbness in elderly patients. However, the exact mechanism of GJG is unclear. This study aimed to investigate the molecular mechanism of the analgesic effect of GJG in a chronic constriction injury model. Results GJG significantly reduced allodynia and hyperalgesia from the early phase (von Frey test, p < 0.0001; cold-plate test, p < 0.0001; hot-plate test p = 0.011; two-way repeated measures ANOVA). Immunohistochemistry and Western blot analysis revealed that GJG decreased the expression of Iba1 and tumor necrosis factor-α in the spinal cord. Double staining immunohistochemistry showed that most of the tumor necrosis factor-α was co-expressed in Iba1-positive cells at day 3 post-operation. GJG decreased the phosphorylation of p38 in the ipsilateral dorsal horn. Moreover, intrathecal injection of tumor necrosis factor-α opposed the anti-allodynic effect of GJG in the cold-plate test. Conclusions Our data suggest that GJG ameliorates allodynia in chronic constriction injury model mice via suppression of tumor necrosis factor-α expression derived from activated microglia. GJG is a promising drug for the treatment of neuropathic pain induced by neuro-inflammation.

Abstract
OBJECTIVES The effect of cinnamaldehyde on the treatment of allergic rhinitis (AR) was investigated in rat model. METHODS Twenty-eight female Wistar albino rats were randomly divided into four groups: Group 1 (control) (C), Group 2 (AR with no treatment) (AR+NoTr), Group 3 (AR+Azelastine HCl) (AR+Aze), and Group 4 (AR+cinnamaldehyde) (AR+Cin). At day 21, AR+Aze rats were given an Azelastine HCl drop, and AR+Cin rats were given cinnamaldehyde intranasally. In all groups, allergic symptoms histopathological results were evaluated. RESULTS The AR+NoTr group showed the worst allergic symptoms, cilia loss and greater inflammation. In the AR+Aze and AR+Cin groups, allergic symptom scores were higher than those in the control group. However, between AR+Aze and AR+Cin groups, there were no significant differences in the allergic symptom scores Histopathological analysis revealed vascular congestion and an increase in goblet cell numbers in the AR+Cin group. However, AR+Cin rat nasal mucosa had less plasma cell infiltration compared with the AR+NoTr group. In rats from the AR+Aze group, analysis of the nasal mucosa revealed less eosinophil infiltration than that seen in the AR+NoTr group. A lower score for mast cell (MC) infiltration was observed in the nasal mucosa of rats treated with Azelastine HCl compared with cinnamaldehyde. CONCLUSIONS In this study we observed that both Azelastine HCl and cinnamaldehyde reduced allergic symptoms in an AR rat model. Cinnamaldehyde decreased vascular congestion as well as plasma cell, eosinophil, and inflammatory cell infiltration into the lamina propria.

Abstract
BACKGROUND/AIMS Functional dyspepsia (FD) is a gastrointestinal disorder in which the patient suffers from chronic abdominal symptoms despite the absence of organic disease. Benachio Q solution (soln.)® is a new prokinetic herbal medicine. The aim of the present study is to determine the efficacy and safety of Benachio Q soln.® in patients with postprandial distress syndrome (PDS) subtype in FD. METHODS A single-center, randomized, double-blind, placebo-controlled pilot study was performed in 20 patients with PDS. Patients were assigned to receive either Benachio Q soln.® or placebo three times a day. After 4 weeks of treatment, the data on response rates, symptoms severity of PDS and gastric emptying time were analyzed to evaluate its efficacy. Adverse events, laboratory tests and vital sign were analyzed to assess its safety. RESULTS Nine patients were assigned to Benachio group and 10 patients to placebo group. The response rate after 4 weeks was 44.4% and 20.0% in Benachio and placebo group, respectively (p=0.350). The response rate during the first week in Benachio group was better compared to that of placebo group with marginal difference (33.3% vs. 0.0%, p=0.087). Changes of severity score in early satiety on second and third week were -1.8 ± 0.6, -1.9 ± 0.4 and -1.3 ± 0.5, -1.4 ± 0.6 in Benachio and placebo group, respectively (p=0.059 vs. p=0.033). No adverse event was observed. CONCLUSIONS The new herbal drug, Benachio Q soln.® seems to improve the symptoms of PDS subtype in FD and could be used safely. Further larger trial is needed in the future.

Abstract
Cinnamon barks extracts have been reported to regulate immune function; however, the component(s) in cinnamon barks responsible for this effect is/are not yet clear. The aim of this study is to find out the possible component(s) that can be used as therapeutic agents for immune-related diseases from cinnamon bark. In this study, the immunosuppressive effects of fraction (named CT-F) and five procyanidin oligomers compounds, cinnamtannin B1, cinnamtannin D1 (CTD-1), parameritannin A1, procyanidin B2, and procyanidin C1, from Cinnamomum tamala or Cinnamomum cassia bark were examined on splenocytes proliferation model induced by ConA or LPS. Then, the effects of activated compound CTD-1 on cytokine production and 2,4-dinitrofluorobenzene (DNFB) induced delayed-type hypersensitivity (DTH) response were detected to evaluate the immunosuppressive activity of CTD-1. It was found that CT-F and CTD-1 significantly inhibited the splenocyte proliferation induced by ConA or LPS. CTD-1 dose-dependently reduced the level of IFN-γ and IL-2 and intensively suppressed DNFB-induced DTH responses. These findings suggest that the immunosuppressive activities of cinnamon bark are in part due to procyanidin oligomers. CTD-1 may be a potential therapeutic agent for immune-related diseases.

Abstract
Cinnamon bark (Cinnamomum zeylanicum Syn C. verum, family: Lauraceae) is one of the oldest traditional medicines for inflammatory- and pain-related disorders. The objective of the present study was to evaluate the efficacy of the polyphenol fraction from Cinnamomum zeylanicum bark (CPP) in animal models of inflammation and rheumatoid arthritis. Dose-response studies of CPP (50, 100, and 200 mg/kg) used in a separate set of in vivo experiments were conducted in acute (carrageenan-induced rat paw edema), subacute (cotton pellet-induced granuloma), and sub-chronic (AIA, adjuvant-induced established polyarthrtis) models of inflammation in rats and the acetic acid-induced writhing model of pain in mice. Effects of CPP on cytokine (IL-2, IL-4, and IFNγ) release from Concanavalin (ConA)-stimulated lymphocytes were also evaluated in vitro. CPP showed a strong and dose-dependent reduction in paw volume, weight loss reversal effects against carrageenan-induced paw edema, and cotton pellet-induced granuloma models in rats. CPP (200 mg/kg p.o. for 10 days) showed a significant reduction in elevated serum TNF-α concentration without causing gastric ulcerogenicity in the AIA model in rats. CPP also demonstrated mild analgesic effects during acute treatment as evidenced by the reduction in the writhing and paw withdrawal threshold of the inflamed rat paw during the acetic acid-induced writhing model and Randall-Selitto test. CPP was found to inhibit cytokine (IL-2, IL-4, and IFNγ) release from ConA-stimulated lymphocytes in vitro. In conclusion, CPP demonstrated prominent action in animal models of inflammation and arthritis and therefore can be considered as a potential anti-rheumatic agent with disease-modifying action.

Protective effects of the traditional herbal formula oryeongsan water extract on ethanol-induced acute gastric mucosal injury in rats. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2012; 2012:438191. [PMID: 23118790 PMCID: PMC3483837 DOI: 10.1155/2012/438191] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/13/2012] [Accepted: 09/19/2012] [Indexed: 01/30/2023]
Abstract
This study was performed to evaluate the protective effect and safety of Oryeongsan water extract (OSWE) on ethanol-induced acute gastric mucosal injury and an acute toxicity study in rats. Acute gastric lesions were induced via intragastric oral administration of absolute ethanol at a dose of 5 mL/kg. OSWE (100 and 200 mg/kg) was administered to rats 2 h prior to the oral administration of absolute ethanol. The stomach of animal models was opened and gastric mucosal lesions were examined. Gastric mucosal injuries were evaluated by measuring the levels of malondialdehyde (MDA), glutathione (GSH), and the activity of antioxidant enzymes. In the acute toxicity study, no adverse effects of OSWE were observed at doses up to 2000 mg/kg/day. Administration of OSWE reduced the damage by conditioning the gastric mucosa against ethanol-induced acute gastric injury, which included hemorrhage, hyperemia, and loss of epithelial cells. The level of MDA was reduced in OSWE-treated groups compared with the ethanol-induced group. Moreover, the level of GSH and the activity of antioxidant enzymes were significantly increased in the OSWE-treated groups. Our findings suggest that OSWE has a protective effect on the gastric mucosa against ethanol-induced acute gastric injury via the upregulation of antioxidant enzymes.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cinnamomum cassia Blume (Aceraceae) has been traditionally used to treat various inflammatory diseases such as gastritis. However, the anti-inflammatory mechanism of Cinnamomum cassia has not been fully elucidated. This study examined the anti-inflammatory mechanism of 95% ethanol extract (Cc-EE) of Cinnamomum cassia. MATERIALS AND METHODS The effect of Cc-EE on the production of inflammatory mediators in RAW264.7 cells and peritoneal macrophages was investigated. Molecular mechanisms underlying the effects, especially inhibitory effects, was elucidated by analyzing the activation of transcription factors and their upstream signaling, and by evaluating the kinase activity of target enzymes. RESULTS Cc-EE of Cinnamomum cassia diminished the production of nitric oxide (NO), tumor necrosis factor (TNF)-α, and prostaglandin (PG)E(2), in lipopolysaccharide (LPS)-activated RAW264.7 cells and peritoneal macrophages in a dose-dependent manner. Cc-EE also blocked mRNA expression of inducible NO synthase (iNOS), cyclooxygenase (COX)-2, and TNF-α by suppressing the activation of nuclear factor (NF)-κB, and simultaneously inhibited its upstream inflammatory signaling cascades, including spleen tyrosine kinase (Syk) and Src. Consistent with these findings, the extract directly blocked the kinase activities of Src and Syk. CONCLUSION Cc-EE exerts strong anti-inflammatory activity by suppressing Src/Syk-mediated NF-κB activation, which contributes to its major ethno-pharmacological role as an anti-gastritis remedy. Future work will be focused on determining whether the extract can be further developed as an anti-inflammatory drug.

Abstract
Antigen-IgE-mediated mucosal mast-cell activation is critical in the development of food allergies. Cinnamaldehyde, a major constituent of Cinnamomi cortex, dose-dependently inhibited the antigen-IgE-induced degranulation of mucosal-type bone-marrow derived mast cells (mBMMCs) and RBL-2H3 cells. Cinnamaldehyde also suppressed the elevation of the intracellular Ca(2+) level that is induced by the extracellular Ca(2+) influx in antigen-IgE-stimulated mBMMCs. Furthermore, tyrosine phosphorylation of phospholipase C (PLC) γ1, which is a crucial activation switch for the intracellular Ca(2+) mobilization in mast cells, was attenuated by cinnamaldehyde. Together, our results demonstrated that cinnamaldehyde suppressed the intracellular Ca(2+) mobilization and the degranulation of mucosal mast cells by inhibiting the activity of the IgE receptor-PLCγ-Ca(2+) influx pathway. These findings suggest that cinnamaldehyde may have therapeutic potential in mucosal mast cell-related allergic diseases, such as food allergies.

Abstract
Nuclear factor-E2-related factor 2 (Nrf2) is an important cytoprotective transcription factor because Nrf2-regulated enzymes play a key role in antioxidant and detoxification processes. Recent studies have reported that lung cancer cells overexpressing Nrf2 exhibit increased resistance to chemotherapy. Suppression of overexpressed Nrf2 is needed for a new therapeutic approach against lung cancers. In the present study, we found that Cinnamomi Cortex extract (CCE) has an ability to suppress Nrf2-regulated enzyme activity and Nrf2 expression in human lung cancer A549 cells with high Nrf2 activity. Moreover, we demonstrated that CCE significantly enhances sensitivity of A549 cells to the cytotoxic action of doxorubicin and etoposide as well as increasing the intracellular accumulation of both drugs. These results suggest that CCE might be an effective concomitant agent to reduce anticancer drug resistance derived from Nrf2 overexpression. Bioactivity-guided fractionation revealed that procyanidin tetramers and pentamers contained in CCE were active components in suppressing Nrf2.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2011; 4:335-41.

Abstract
Pharmacological actions of Mokuboito and its constituents (Sinomenium acutum and sinomenine) on rat aorta were examined. Mokuboito and S. acutum at lower concentrations (0.03-1 mg ml(-1)) contracted the non-loaded aorta, but at higher concentrations (1-3 mg ml(-1)), reversed to dilate it. The vasoconstriction was blocked by phentolamine (10 muM). Sinomenine failed to exhibit the vasoconstriction. On the other hand, Mokuboito and S. acutum dilated the NE (5 muM)-induced vasoconstriction: at 3 mg ml(-1), by 98.9 +/- 2.5% (n = 6, P < 0.01) and 97.0 +/- 4.8% (n = 6, P < 0.01). Vasorelaxation induced by Mokuboito and S. acutum was attenuated by indomethacin, L-NMMA and nicardipine. Propranolol decreased the vasorelaxation induced by Mokuboito, but not by S. acutum. Sinomenine also relaxed the constriction and at 100 muM, by 68.8 +/- 5.1% (n = 7, P < 0.01). This vasorelaxation was attenuated by indomethacin, L-NMMA and nicardipine, and also by propranolol. Therefore, these results indicate that Mokuboito and its constituents exert both vasodilating actions mediated by endothelium-dependent mechanisms (PGI(2) and NO from endothelium) and by endothelium-independent mechanisms (Ca(2+) influx control on smooth muscle cells). Simultaneously, Mokuboito and S. acutum cause the vasoconstrictions mediated through alpha-adrenoceptor stimulation, but not sinomenine. Also, Mokuboito and sinomenine possess beta-adrenoreceptor stimulating action, but not S. acutum.

Abstract
The standard treatment of prurigo nodularis (PN) includes antihistamines, ultraviolet light, and topical and systemic corticosteroids; unfortunately, PN is notoriously resistant to the conventional therapy. Herewith is described one case of PN, which was initialized with herose as the first-line therapy resulting in complete clinical clearance. Results of follow-up examinations from 2005 to 2009 showed no evidence of recurrence. Findings indicate that herose monotherapy is a potentially promising therapeutic options for PN.

Abstract
OBJECTIVE We examined the ultrastructural morphology (number of collagen fibrils, mean and mass-averaged diameter) of isolated and combined treatments of a therapeutic laser and herbs for medial collateral ligament (MCL) injury in rats. MATERIALS AND METHODS Twenty-eight rats, divided into seven groups: laser (L), herb (H), laser + herb (LH), laser control (LC), herb control (HC), laser sham (LS) and herb sham (HS), were studied. Right MCL of groups L, H, LH, LC and HC were transected, while that of LS and HS remained intact. Group L received 9 treatment sessions of GaAlAs laser with a dosage of 3.5 Jcm(-2); group H received herbal plaster treatment; groups LH had combined treatments of laser and herb; group LC had placebo laser; group LS had no treatment; groups HC and HS received only bandage without herb. All MCLs were analyzed using transmission electron microscopy at 3 weeks. RESULTS Differences (p < 0.05) existed in mean fibril diameters among groups. Core mass-averaged diameters of groups L and H were larger than the control groups (LC and HC). Fibril diameter of group LH (combined treatment) was even larger and approaching that of the intact MCL. CONCLUSION Combined therapeutic laser and herbal treatment hastened collagen fibril maturation in MCL repair.

Abstract
Hachimi-jio-gan is widely used to improve several disorders associated with diabetes, but its mechanism remains poorly understood. In an attempt to clarify the mechanism of Hachimi-jio-gan, we investigated the effects of this herbal medicine and its components in transfection studies of CV1 cells, especially nuclear receptor-mediated actions. One half (0.5) mg/ml of Hachimi-jio-gan activated peroxisome proliferator-activated receptor (PPARalpha), mediating the activation by 3.1-fold on DR1 response elements; however, it did not affect PPARgamma, thyroid hormone receptor, androgen receptor, estrogen receptor or RXR. In addition, this activation was observed in a dose-dependent manner. Next, to determine which components of Hachimi-jio-gan activate PPARalpha-mediated transcription, 8 of its components (rehmanniae radix, orni fructus, dioscoreae rhizoma, alismatis rhizoma, hoelen, moutan cortex, cinnamomi cortex, aconiti) were tested. Only cinnamomi cortex (1.0 mg/ml) increased PPARalpha-mediated transcription by 4.1-fold, and this activation was specific for PPAR alpha, and not for other nuclear receptors. Moreover, this PPARalpha-related activation by cinnamomi cortex is specifically observed in renal cells. Taken together, these findings indicate that Hachimi-jio-gan and cinnamomi cortex may have a pharmacological effect through the target site for PPARalpha.

Abstract
AIM: To clarify the mechanism underlying the anti-diabetic activities of cortex cinnamomi extract (CCE).
METHODS: To induce in vivo diabetes, mice were injected with streptozotocin (STZ) via a tail vein (100 mg STZ/kg body weight). To determine the effects of CCE, mice were administered CCE twice daily for 7 d by oral gavage starting 1 wk before the STZ injection. Blood glucose and plasma insulin concentration were measured as an index of diabetes. Also, to induce cytotoxicity of RINm5F cells, we treated with cytokines (IL-1β (2.0 ng/mL) and IFN-γ (100 U/mL)). Cell viability and nitric oxide production were measured colorimetrically. Inducible nitric oxide synthase (iNOS) mRNA and protein expression were determined by RT-PCR and Western blotting, respectively. The activation of NF-κB was assayed by using gel mobility shift assays of nuclear extracts.
RESULTS: Treatment of mice with STZ resulted in hyperglycemia and hypoinsulinemia, which was further evidenced by immunohistochemical staining of islets. However, the diabetogenic effects of STZ were completely prevented when mice were pretreated with CCE. The inhibitory effect of CCE on STZ-induced hyperglycemia was mediated through the suppression of iNOS expression. In rat insulinoma RINm5F cells, CCE completely protected against interleukin-1β and interferon-γ-mediated cytotoxicity. Moreover, RINm5F cells incubated with CCE showed significant reductions in interleukin-1β and interferon-γ-induced nitric oxide production and in iNOS mRNA and protein expression, and these findings correlated well with in vivo observations.
CONCLUSION: The molecular mechanism by which CCE inhibits iNOS gene expression appears to involve the inhibition of NF-κB activation. These results reveal the possible therapeutic value of CCE for the prevention of diabetes mellitus progression.

Abstract
The present study investigated the effects of combined therapeutic laser and herbal medication protocols on injured medial collateral ligaments (MCLs) of rat knees. Fully 36 rats were evenly divided into 9 groups. Right MCLs of groups 1 to 6 and 8 were transected, while that of groups 7 and 9 remained intact. After surgery, group 1 was treated with 1 session of high-dosed laser; group 2 with 9 sessions of low-dosed laser; group 3 with an herbal plaster; groups 4 and 5 received combined treatments of groups 1 and ss and 2, and 3 respectively; groups 6 and 7 received only bandaging; groups 8 and 9 received placebo laser and no treatment, respectively. All MCLs were subjected to biomechanical testing at 3 weeks postsurgery. Results revealed significant differences among groups in ultimate tensile strength (UTS) and stiffness (p < 0.01). Combination of multiple low-dosed laser treatment with herbal treatment (group 5) resulted in higher UTS than either no treatment (groups 6 and 8), single high-dosed laser treatment (group 1), multiple low-dosed laser treatment (group 2), or herbal treatment (group 2) alone. We concluded that combined applications of laser and herb can enhance further biomechanical properties of repairing rat MCLs than separate applications at 3 weeks postinjury.

Abstract
Herbal remedies have been reported to be effective in controlling inflammation for acute soft tissue injuries. There exist, however, no reports of their effects on collagen production and remodeling; thus mechanical strength studies of the tissues have not been reported. This study tested the effects of a herbal remedy on the strength of healing medial collateral ligaments (MCL) in rats. Sixteen rats receiving surgical transection to their right MCLs and eight receiving sham operation were tested. Eight of the MCL-injured animals were treated with an adhesive herbal plaster application to their right knees, while the other eight in the MCL injured group and the sham group were treated with plain adhesive plaster to their right knees. The MCLs were harvested and tested at either 3 or 6 weeks post-operation. The ultimate tensile strength (UTS) and stiffness normalized to the uninjured side of each animal of the herb and sham groups were significantly larger than those of the control at both 3 and 6 weeks (p = 0.001). No significant difference was found in stiffness between the herb and sham groups (p > 0.05). We concluded that the herbal remedy improves the UTS and stiffness of repairing MCLs at 3 and 6 weeks after injury.

Abstract
Juzen-taiho-to, a Kampo formula, originally consists of a mixture of Shimotsu-to and Shikunshi-to formulas together with two other crude ingredients. Juzen-taiho-to is reported to have a preventive effect on endometrial carcinogenesis in mice. Shimotsu-to exerts an inhibitory effect on estrogen-induced expression of c-fos, interleukin (IL)-1alpha and tumor necrosis factor (TNF)-alpha in uteri of ovarectomized mice. In the present study, short- and long-term experiments were designed to determine the effects of Juzen-taiho-to and Shimotsu-to on the estrogen-related endometrial carcinogenesis in mouse uteri, associated with the expression of cyclooxygenase (COX)-1 and -2. In the short-term experiment, exposure to Juzen-taiho-to or Shimotsu-to significantly reduced estradiol-17beta (E(2))-stimulated expressions of COX-2 mRNA (p<0.05) as well as the protein. However, no effects on the expression of COX-1 were observed. Shikunshi-to did not affect COX expression. In the long-term experiment, 90 female ICR mice were given N-methyl-N-nitrosourea (MNU) into their uterine corpora. The animals were divided into four groups as follows: group 1, a diet containing 0.07% Shimotsu-to and 5 ppm E(2); group 2, a diet containing 5 ppm E(2); group 3, a diet containing 0.07% Shimotsu-to; group 4 served as a control. Exposure of Shimotsu-to reduced the incidence of MNU- and E(2)-induced endometrial adenocarcinoma and atypical hyperplasia at the termination of the experiment (30 weeks). The above findings and our previous reports suggest that Shimotsu-to is responsible for the preventive effects of Juzen-taiho-to on estrogen-related endometrial carcinogenesis in mice, through the inhibition of estrogen-related COX-2 as well as c-fos, IL-1alpha and TNF-alpha expressions.

Abstract
The present study investigated the effects of an external herbal application on the ultrastructural morphology of repairing medial collateral ligament (MCL) in a rat model. Eight MCL-transected/herb-treated rats (group 1) were compared with 8 MCL-transected/placebo-treated controls (group 2) and 8 MCL-intact/placebo-treated rats (group 3). At 3 and 6 weeks posttransection, MCL specimens were examined under electron microscope. With analysis of 370,709 collagen fibrils, all herb-treated animals had significantly larger fibrils than the controls (p < .001) at 6 weeks postinjury. The mean diameter of those peripheral collagen fibrils of group 1 was larger than the sham group (p < .001). The mass-averaged diameters of group 1 (50.49 to 143.07 nm) and group 3 (59.69 to 188.88 nm) were larger than group 2 (50.59 to 121.94 nm). The area coverage by collagen fibrils ranged from 46.86 to 94.97% for group 1 and 43.70 to 68.08%f or group 3 as compared with 40.01 to 50.77% for group 2. Mode obliquity was 0.56 to 0.84 among groups. We concluded that herbal remedy increases collagen fibril size of healing rat MCLs homogeneously at 6 weeks posttransection.

Abstract
Selective serotonin reuptake inhibitors (SSRIs) are apt to cause gastrointestinal adverse events such as nausea and dyspepsia. Gorei-san (TJ-17), which is composed of five herbs (Alismatis rhizoma, Atractylodis lanceae rhizoma, Polyporus, Hoelen, and Cinnamomi cortex), is a Japanese herbal medicine that has been used to treat nausea, dry mouth, edema, headache, and dizziness. The authors investigated the efficacy of TJ-17 for patients who experienced nausea or dyspepsia induced by SSRIs. Twenty outpatients who experienced nausea or dyspepsia induced by SSRIs were recruited for the study. Seventeen patients were female, three were male, and patient age ranged from 21 to 74 years (49.8 +/- 17.0 years). TJ-17 was added to the previous regimen. Nausea and dyspepsia disappeared completely in nine patients, decreased in four patients, decreased slightly in two patients, and did not change in five patients. No adverse events were associated with the addition of TJ-17 in any patient.
