Abstract
Hochu-ekki-to (HET) is a traditional Japanese herbal (Kampo) medicine for the treatment of severe weakness, loss of appetite, and indigestion in elderly patients and for the prevention of opportunistic infections. The impact of HET on patients with chronic wounds refractory to conventional therapies was investigated in a prospective, randomized trial, including 18 patients divided into medication (7.5 g oral HET per day, n = 9) and control (n = 9) groups. Wound healing during the 12-week study period was scored based on depth, exudate, size, inflammation/infection, granulation tissue, necrotic tissue, and pocket size. At 12 weeks, wound healing progressed in all nine patients in the medication group, whereas wound healing progressed in only three patients in the control group (significant difference, p < 0.01; relative risk: 3.00). In the medication group, the total score decreased significantly at 8 weeks and later. To the best of our knowledge, this study was the first to show that HET promoted the healing of chronic wounds resistant to conventional treatments. HET may be a choice as an adjunctive therapy for chronic wounds, particularly for patients with malnutrition. This trial was registered with the University Hospital Medical Information Network Clinical Trials Registry (UMIN000031620).

[PMID: 30071688 PMCID: PMC6163422 DOI: 10.3390/medicines5030083] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/29/2018] [Revised: 07/24/2018] [Accepted: 07/25/2018] [Indexed: 11/16/2022]
Abstract
Background: Methicillin-resistant Staphylococcus aureus (MRSA) infections are largely preceded by colonization with MRSA. Hochuekkito is the formula composing 10 herbal medicines in traditional Kampo medicine to treat infirmity and to stimulate immune functions. We evaluated the efficacy of hochuekkito extract (HET) against MRSA colonization using a nasal infection murine model. Methods: We evaluated the effects of HET as follows: (1) the growth inhibition by measuring turbidity of bacterial culture in vitro, (2) the nasal colonization of MRSA by measuring bacterial counts, and (3) the splenocyte proliferation in mice orally treated with HET by the 3H-thymidine uptake assay. Results: HET significant inhibited the growth of MRSA. The colony forming unit (CFU) in the nasal fluid of HET-treated mice was significantly lower than that of HET-untreated mice. When each single crude drug—Astragali radix, Bupleuri radix, Zingiberis rhizoma, and Cimicifugae rhizome—was removed from hochuekkito formula, the effect of the formula significantly weakened. The uptake of 3H-thymidine into murine splenocytes treated with HET was significantly higher than that from untreated mice. The effects of the modified formula described above were also significantly weaker than those of the original formula. Conclusions: Hochuekkito is effective for the treatment of MRSA nasal colonization in the murine model. We suggest HET as the therapeutic candidate for effective therapy on nasal cavity colonization of MRSA in humans.

Abstract
We examined the effect of Kampo on the replication of ganciclovir (GCV)-resistant human cytomegalovirus (HCMV) in the human embryonic fibroblast cell line MRC-5. Treatment of HCMV-infected cells with Sho-seiryu-to (SST; Xiao-Qing-Long-Tang in Chinese) resulted in the inhibition of viral replication without affecting the cell growth. SST treatment decreased the synthesis of viral DNA, but had no virucidal effect on cell-free HCMV. However, the inhibitory effect of SST on HCMV replication was ablated by anti-interferon-β (IFN-β) antibody suggesting that SST inhibits the replication of GCV-resistant HCMV through the induction of IFN-β. These results suggest that SST is a novel compund with potential as an anti-HCMV.

Abstract
Panax ginseng Meyer has been widely used as a tonic in traditional Korean, Chinese, and Japanese herbal medicines and in Western herbal preparations for thousands of years. In the past, ginseng was very rare and was considered to have mysterious powers. Today, the efficacy of drugs must be tested through well-designed clinical trials or meta-analyses, and ginseng is no exception. In the present review, we discuss the functions of ginseng described in historical documents and describe how these functions are taken into account in herbal prescriptions. We also discuss the findings of experimental pharmacological research on the functions of ginseng in ginseng-containing prescriptions and how these prescriptions have been applied in modern therapeutic interventions. The present review on the functions of ginseng in traditional prescriptions helps to demystify ginseng and, as a result, may contribute to expanding the use of ginseng or ginseng-containing prescriptions.

Abstract
Hochu-ekki-to is a traditional herbal (Kampo) medicine that has been shown to be effective for patients with Kikyo (delicate, easily fatigable, or hypersensitive) constitution. Previous case reports have suggested that this herbal drug was effective for a certain subgroup of patients with atopic dermatitis (AD). We aimed to evaluate the efficacy and safety of Hochu-ekki-to in the long-term management of Kikyo patients with AD. In this multicenter, double blind, randomized, placebo-controlled study, 91 Kikyo patients with AD were enrolled. Kikyo condition was evaluated by a questionnaire scoring system. All patients continued their ordinary treatments (topical steroids, topical tacrolimus, emollients or oral antihistamines) before and after their protocol entry. Hochu-ekki-to or placebo was orally administered twice daily for 24 weeks. The skin severity scores, total equivalent amount (TEA) of topical agents used for AD treatment, prominent efficacy (cases with skin severity score = 0 at the end of the study) rate and aggravated rate (more than 50% increase of TEA of topical agents from the beginning of the study) were monitored and evaluated. Seventy-seven out of 91 enrolled patients completed the 24-week treatment course (Hochu-ekki-to: n = 37, placebo: n = 40). The TEA of topical agents (steroids and/or tacrolimus) was significantly (P < 0.05) lower in the Hochu-ekki-to group than in the placebo group, although the overall skin severity scores were not statistically different. The prominent efficacy rate was 19% (7 of 37) in the Hochu-ekki-to group and 5% (2 of 40) in the placebo group (P = 0.06). The aggravated rate was significantly (P < 0.05) lower in the Hochu-ekki-to group (3%; 1 of 37) than in the placebo group (18%; 7 of 39). Only mild adverse events such as nausea and diarrhea were noted in both groups without statistical difference. This placebo-controlled study demonstrates that Hochu-ekki-to is a useful adjunct to conventional treatments for AD patients with Kikyo constitution. Use of Hochu-ekki-to significantly reduces the dose of topical steroids and/or tacrolimus used for AD treatment without aggravating AD.

Abstract
We examined the effect of three types of Kampo medicines on human cytomegalovirus (CMV) replication in the human embryonic fibroblast cell line, MRC-5. Treatment of cells with at least 0.01 μg/ml of Kampo medicines inhibited the cytopathic effects of CMV-infected MRC-5 cells. Moreover, Kampo medicine decreased the replication of CMV without affecting the inhibition of host cells, with a concomitant decrease in CMV DNA levels. However, Kampo medicine demonstrated no virocidal effect on cell-free CMV. Furthermore, western blotting analysis demonstrated that the Kampo medicine decreased the amount of 65 kDa late antigen expression in the infected cells. These results suggest that Kampo medicine may be sufficient to inhibit viral DNA replication and late protein synthesis, resulting in anti-CMV effects. Therefore, these three Kampo medicines have the potential of being a source of new powerful anti-CMV compounds.

Abstract
To investigate the immunological effect of the traditional Japanese herbal medicine (kampo), Hochu-ekki-to (HOT), on dendritic cells (DC), we examined in vitro if HOT would stimulate the maturation process of human monocyte-derived DC as do TNF-alpha and LPS. Monocytes from a healthy volunteer were cultured in the presence of IL-4 and GM-CSF, and the generated immature DC were stimulated with HOT, TNF-alpha, or LPS (HOT-DC, TNF-DC, and LPS-DC, respectively) for 2 days. Flow cytometric analysis showed that HOT stimulated DC to express the surface maturation markers CD80, CD83, and CD86 dose-dependently and that the up-regulation level was identical to TNF-alpha and LPS. The antigen-uptake capacity of HOT-DC was determined by FITC-labeled albumin uptake. HOT-DC lost albumin uptake capacity comparable to LPS-DC, indicating DC maturity. IL-12 (p70) production by HOT-DC and TNF-DC was not increased in comparison with LPS-DC. The antigen-presenting capacity of HOT-DC as analyzed by allogeneic T cell proliferation was significantly increased in comparison with immature DC and was identical to LPS-DC. These results demonstrate that HOT stimulates DC maturation as well as the other known maturation factors, despite low IL-12 production, and suggests the possibility that DC maturation by HOT can play an important role in the improvement of the immunoregulatory function in patients with impaired host defense.

Abstract
Atopic dermatitis (AD) is a complex disease of obscure pathogenesis. A substantial portion of AD patients treated with conventional therapy become intractable after several cycles of recurrence. Over the last 20 years we have developed an alternative approach to treat many of these patients by diet and Kampo herbal medicine. However, as our approach is highly individualized and the Kampo formulae sometimes complicated, it is not easy to provide evidence to establish usefulness of this approach. In this Review, to demonstrate the effectiveness of the method of individualized Kampo therapy, results are presented for a series of patients who had failed with conventional therapy but were treated afterwards in our institution. Based on these data, we contend that there exist a definite subgroup of AD patients in whom conventional therapy fails, but the ‘Diet and Kampo’ approach succeeds, to heal. Therefore, this approach should be considered seriously as a second-line treatment for AD patients. In the Discussion, we review the evidential status of the current conventional strategies for AD treatment in general, and then specifically discuss the possibility of integrating Kampo regimens into it, taking our case-series presented here as evidential basis. We emphasize that Kampo therapy for AD is more ‘art’ than technology, for which expertise is an essential pre-requisite.

Abstract
We evaluated the effect of bu-zhong-yi-qi-tang, a prescription of traditional Oriental medicine, and its major ingredients on protection of the intestine and hematopoietic organs against radiation damage in this study. The jejunal crypt survival, endogenous spleen colony formation, and apoptosis in jejunal crypt cells were investigated in mice irradiated with high and low doses of gamma-rays. bu-zhong-yi-qi-tang administration before irradiation protected the jejunal crypts (p < 0.0001), increased the formation of the endogenous spleen colony (p < 0.05) and reduced the frequency of radiation-induced apoptosis (p < 0.05). In experiments on the effects of the individual ingredient of bu-zhong-yi-qi-tang, Rensan (Radix Ginseng), Danggui (Radix Angelicae gigantis), Shengma (Rhizoma Cimicifugae) and Chaihu (Radix Bupleuri) might have major radioprotective effects, and each might have different degrees of effect on these three endpoints. These results indicated that bu-zhong-yi-qi-tang might be a better agent than any one of its ingredients to satisfy all three endpoints. Although the mechanisms of this inhibitory effect remain to be elucidated, these results indicated that bu-zhong-yi-qi-tang might be a useful radioprotector, especially since it is a relatively non-toxic natural product. Further studies are needed to better characterize the protective nature of bu-zhong-yi-qi-tang extract and its ingredients.

Abstract
A new mixed formula of Chinese herbs containing Shin-yi-san + Xiao-qing-long-tang + Xiang-sha-liu-jun-zi-tang by the weight of 9 + 3 + 3 g/day was prescribed for the treatment of patients with perennial allergic rhinitis for 3 months (the composition of each herb is shown in the tables of the article). We classified the patients into high (H-IgE) and low IgE (L-IgE) groups according to the titer of serum total IgE (> 200 KIU/l in H-IgE vs. < 200 KIU/l in L-IgE) and the presence of house dust mite-specific IgE. The nasal symptomatic score in the high IgE group was significantly improved from 7.19 +/- 0.18 before treatment to 2.67 +/- 0.37 after treatment. In addition, the serum total and house dust mite-specific IgE level were also decreased after treatment. For elucidating the working mechanism of the mixed formula, the Th1 (IFN-gamma) and Th2 (IL-4, IL-5, IL-10 and IL-13) cytokine production by phytohemagglutinin (PHA)-stimulated mononuclear cells (2 x 10(6) cells/ml) and cyclooxygenase type 2 (COX-2) mRNA expression in LPS or IL-13-stimulated PMN were compared before and after 3 months of treatment. We found that the mixed formula treatment significantly enhanced IL-10 but decreased IFN-gamma and IL-5 production by PHA-stimulated mononuclear cells. The IL-5 production was also decreased by PHA-stimulated lymphocyte. In addition, the COX-2 mRNA expression in stimulated PMN was significantly suppressed after treatment. These results suggest that the new mixed formula treatment is beneficial to the patients with perennial allergic rhinitis via modulating the function of lymphocytes and neutrophils.

Abstract
In this study, the effect of traditional Japanese (Chinese) medicine, Bu-zhong-yi-qi-tang (Japanese name: Hochu-ekki-to, HOT), on the restraint stress treatment (RST)-induced susceptibility against Listeria monocytogenes (L. monocytogenes) was examined. When RST was performed every day for 10 h from the day of infection, the bacterial numbers were increased at 3 and 5 days after the infection. Oral pretreatment with HOT for 7 days prevented such increases. Pretreatment with HOT prevented the suppression of antigen-specific IFN-gamma production by RST. HOT also prevented suppression of macrophage accumulation, including MHC-class II positives, in the peritoneal cavity and their bactericidal activity by RST. HOT suppressed the serum corticosterone level elevated by RST in infected mice. Taken together, the suppression of corticosterone using HOT participates in the prevention of suppressions of the bactericidal activity of macrophages, migration of macrophages and antigen-specific IFN-gamma production of Th1 cells by RST. Our findings suggest that HOT is a useful drug for patients suffering from stress disease to reduce the susceptibility to bacterial infection.

Abstract
The effect of a Japanese ethical herbal drug, Hochu-ekki-to (HOT), on recovery from leukopenia induced by cyclophosphamide (CY) was investigated. Daily oral administration of 1000 mg/kg HOT into CY-treated mice significantly prevented decrease of leukocyte numbers in the peripheral blood and accelerated recovery from leukopenia. Ginsenoside Rgl extracted from Ginseng radix, a major herb of HOT, was one of the active ingredients. HOT increased numbers of neutrophils and monocytes in the peripheral blood compared with CY-treated control. Moreover, HOT augmented the resistance against Pseudomonas aeruginosa infection. The number of colony-forming units in the spleen (CFU-S) also increased in HOT-treated mice. The frequencies of IL-3-, GM-CSF- and IFN-gamma-producing cells increased in the spleen, bone marrow, liver and IEL on HOT treatment, and HOT clearly augmented the expressions of IL-3, GM-CSF and IFN-gamma mRNA in the spleen, bone marrow, liver and IEL except IL-3 and IFN-gamma mRNA in the IEL. These results suggest that HOT enhances the production of hematopoietic lymphokines, stimulates the proliferation of hematopoietic progenitor cells and consequently accelerates recovery from leukopenia in CY-treated mice. Additionally, IFN-gamma which HOT-augmented the production may contribute the protective effect against the bacterial infection by activating of phagocyte cells.

Abstract
We previously reported that restraint stress impairs the antitumor immune responses through its suppressive effect on the Th1-type cytokine production from CD4+ T cells. In this study, we investigated a potential of Hochu-ekki-to (TJ-41:Bu-Zhong-Yi-Qi-Tang) to restore stress-induced immunosuppression. The oral administration of TJ-41 was able to improve a decreased cellularity in the lymph node and spleen and to improve an inhibition of tumor-specific Th1-type cytokine production, both of which were induced by repeated restraint stress in tumor-bearing mice. The oral administration of TJ-41 also induced a partial recovery of the antitumor cytolytic activity in the stress-burdened tumor-bearing mice. More importantly, the growth of tumors in stress-burdened preimmunized mice was obviously inhibited by TJ-41, and resulted in tumor-free state in 75% of the mice. Regarding the mechanisms by which TJ-41 restored the antitumor responses in stress-burdened mice, we found that the serum levels of corticosterone and interleukin-12 were normalized by TJ-41. In addition, the expression of CD80 and CD86, which both decreased in the stress-burdened mice, was restored to the normal level by TJ-41. Taken together, our results indicate that the oral administration of TJ-41 is able to restore the antitumor T cell responses in stress-burdened tumor-bearing mice by normalizing the serum corticosterone, interleukin-12 and the expression of costimulatory molecules.

Abstract
The innate immunity against murine cytomegalovirus (MCMV) at the early phase of infection is mediated by NK cells and macrophages. We studied the effects of hochu-ekki-to (HET), a traditional Chinese herbal medicine, on the regulation of innate immunity mediated by NK cells and macrophages. We found the oral administration of HET to increase both the number of leukocytes in the spleen and liver and the splenic NK cell cytotoxicity associated with the increased induction of serum IFN-alpha/beta after an MCMV infection but it had no effect on liver NK cells. However, no differences were found in the serum IL-12, IFN-gamma, TNF-alpha and nitric oxide (NO) production in the culture of macrophages between the HET- and PBS-treated mice on day 2 after MCMV infection. In addition, HET-treated splenic and peritoneal macrophages were found to show a higher intrinsic resistance against in vitro MCMV infection than that of PBS-treated mice. Therefore, the HET-induced effects on NK cells and macrophages selectively reduced the viral load in the spleen but not in the liver at an early phase of MCMV infection. HET may thus be useful in the treatment of human cytomegalovirus infection which commonly occurs in HIV-infected AIDS patients.

Abstract
The protective effect against an oral infection with Listeria monocytogenes was observed in BALB/c mice who were orally administered a traditional Chinese medicine, Bu-zhong-yi-qi-tang (Japanese name: Hochu-ekki-to, HOT) daily for 7 days. Bacterial numbers in the Peyer's patch (PP) at 18 h, in the mesenteric lymph nodes (MLN) at 18 h, 1 day and 3 days and in the liver at 3 days after infection were significantly suppressed in HOT-treated mice, although there was no difference in the bacterial number in the small intestinal contents. The enhanced bactericidal activities of PP and liver macrophages by pretreatments of HOT were observed. The protective effect of HOT was not observed in athymic nu/nu and IFN-gamma deficient mice. The administration of HOT increased IFN-gamma-producing cells in the intestinal intraepithelial lymphocytes (IEL) but did not in the PP, MLN and liver. HOT exerts effects mainly on CD8alphabeta+ IEL which are thymus-dependent, and induced IFN-gamma production from their cells. These results suggest that HOT acts on the gut-associated lymphoid tissues and induces IFN-gamma from CD8alphabeta+ IEL, which activates PP and liver macrophages and consequently the resistance to L. monocytogenes is augmented in the mice.

Abstract
Resistance to many pathogens, such as Listeria monocytogenes, is correlated with the host's capacity to generate a ThI cell-mediated immune response in which delayed-type hypersensitivity (DTH) is activated. A wide variety of antigens induce down-regulation of DTH when introduced into the anterior chamber of the eye. This immunoregulatory phenomenon has been termed anterior chamber-associated immune deviation (ACAID) and is believed to be a primary mechanism for the immune privilege of the anterior chamber. Suppression of DTH, as a result of anterior chamber priming, could carry significant risk to the host's well-being as the resistance to many pathogens relies heavily on DTH-dependent ThI responses. Studies were performed to determine if a bacterial pathogen, L. monocytogenes, introduced into the anterior chamber of the eye would induce a down-regulation of systemic DTH. Intracameral inoculation of infectious L. monocytogenes into genetically susceptible C3H and BALB/c mice did not induce suppression of DTH, but instead resulted in a significant footpad swelling response to bacterial antigens. Likewise, intracameral inoculation of L. monocytogenes into genetically resistant C57BL/6 mice also induced vibrant bacterial-specific DTH. Using an in-vitro model of ACAID, we showed that macrophage suspensions that were simultaneously exposed to L. monocytogenes and bovine serum albumin (BSA) antigens, in the presence of aqueous humor (AH), induced listerial-specific DTH responses, yet simultaneously induced suppression of BSA-specific DTH. Collectively, the results indicate that immune privilege is not extended to all foreign antigens that enter the anterior chamber of the eye, and as a result, some intraocular antigens can provoke strong systemic DTH. However, non-ACAID-inducing antigens do not prejudice the down-regulation of DTH by other antigens which normally induce ACAID.

Abstract
The ability of a traditional herbal medicine, Bu-zhong-yi-qi-tang (Japanese name: Hochu-ekki-to, HOT), to suppress IgE production was investigated. BALB/c mice were intraperitoneally immunized with aluminium hydroxide adsorbed with DNP-KLH (DNP-KLH + alum). When oral administration of HOT was begun just after immunization, the serum level of antigen-specific IgE was significantly decreased, although those of antigen-specific IgG1 and IgG2a were not influenced. In the culture of spleen cells obtained 14 days after immunization with DNP-KLH, antigen-specific IgE and IgG1 production by the cells of the HOT-treated mice was significantly suppressed compared to that in immunized mice. Furthermore, in the combination culture with CD4+ T cells and B cells separated from spleen cells, IgE production by the cells from immunized mice was inhibited by replacement of their corresponding cell population with either CD4+ T cells or B cells of HOT-treated mice. Additionally, production of interleukin 2 (IL-2) and IL-4 was significantly suppressed in HOT-treated mice but not that of IFN-gamma in comparison to the immunized mice. These results suggested that HOT decreased the IgE level in serum by inhibiting the development of IL-4-producing CD4+ T cells.

Abstract
The oral administration of a kampo herbal medicine, Hochu-ekki-to (TJ-41: Bu-Zhong-Yi-Qi-Tang) using a water-supplying bottle resulted in a slight but significant inhibition of Meth A growth. The oral administration of TJ-41 with gastric gavage significantly enhanced the specific antitumor activity against Meth A at rechallenge on day 9. In a tumor-neutralizing assay, the tumor draining LN cells of the TJ-41 administered mice showed an antitumor activity against Meth A. In a cytolytic assay, the anti-Meth A specific cytolytic T lymphocyte activity was not detected in the spleen cells of the Meth A bearing and TJ-41 administered mice. The oral administration of TJ-41 enhanced the natural killer (NK) activity of the spleen cells in naive mice but could not improve the decreased NK activity of spleen cells from the tumor bearing mice. In a cytostatic assay, the peritoneal exudate cells from the Meth A bearing and TJ-41 administered mice showed a significantly higher amount of cytostatic activity against Meth A than that from either Meth A bearing or TJ-41 administered mice. These results indicate that the oral administration of TJ-41 into the tumor bearing mice may thus be able to enhance concomitant antitumor immunity through the augmentation of the cytostatic activity.
