Abstract
Background Hochuekkito extract (HET) has multiple effects through the digestive and immune systems, including for acute viral infection and chronic inflammation. We review basic pharmacological and clinical researches of HET and discuss the effects of HET against the pandemic COVID‐19. Methods We reviewed pharmacological studies from 1996 to 30 April 2020 that used experimental animals orally treated with HET and randomized controlled trials (RCTs) from 2000 to 30 April 2020. Results Altogether, 64 pharmacological studies reported immuno‐stimulatory effects against infection and cancer, immuno‐modulative effects against allergy and some inflammatory diseases, and ameliorating effects against exhaustion and frailty. Nine RCTs showed improvement of pulmonary Mycobacterium avium complex disease on chest X‐ray; improved systemic inflammation, nutrition, and quality of life of patients with chronic obstructive pulmonary disease and a decrease in the number getting common cold and exacerbations; reduction of soluble interleukin‐2 receptor and the serum cortisol concentration of postoperative patients; a reduction of the incidence of inflammatory complications and C‐reactive protein elevation after cerebrovascular disease; a reduction of the volume of steroid and tacrolimus during the treatment of atopic dermatitis; a healing effect for intractable chronic wounds; improvement of the physical status of elderly weak patients; and improvement of the fatigue level of cancer patients. Conclusion CODIV‐19 is characterized by high risk for the aged and people with other disease complications, cytokine hyperactivity in the severe stage, and sequelae in the recovery stage. Considering the immune‐stimulative/modulative effects of HET on inflammatory conditions and against exhaustion and frailty, it may be useful for prevention, treatment, and recovery from COVID‐19.

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).

Abstract
The immune system plays an important role in protection against infection and cancer, and in the maintenance of the internal environment of the body. However, such important immune functions are known to decline with age in many mammals, including humans. It is a matter of clinical importance that the incidence of various age-associated diseases such as infections, cancer, and vascular disorders increases with a decrease in immunological vigor. The extent of immunologic decline is variable and exhibits wide interindividual variations. Thus, it is important to assess the extent of immunologic decline in both patients suffering from various diseases and in healthy people in order to maintain healthy conditions. To this end, we have developed a scoring system that analyzes immune parameters according to a database of known age-associated immune changes obtained from a healthy population. Using this scoring system, we can combine several different immunological parameters and express the immune status of individuals as a simple numeral. Several methods of immunological restoration were introduced and the magnitude of restoration was evaluated by the quantitative assessment of immunological level.

Abstract
Amyotrophic lateral sclerosis (ALS) is a motor neuron disease characterized by progressive motor function impairment, dysphagia, and respiratory failure. Owing to the complexity of its pathogenic mechanisms, an effective therapy for ALS is lacking. Herbal medicines with multiple targets have good efficacy and low adverse reactions for the treatment of neurodegenerative diseases. In this study, the effects of Bojungikgi-tang (BJIGT), an herbal medicine with eight component herbs, on muscle and spinal cord function were evaluated in an ALS animal model. Animals were randomly divided into three groups: a non-transgenic group (nTg, n = 24), a hSOD1G93A transgenic group (Tg, n = 24), and a hSOD1G93A transgenic group in which 8-week-old mice were orally administered BJIGT (1 mg/g) once daily for 6 weeks (Tg+BJIGT, n = 24). The effects of BJIGT were evaluated using a rotarod test, foot-printing, and survival analyses based on Kaplan-Meier survival curves. To determine the biological mechanism underlying the effects of BJIGT in hSOD1G93A mice, western blotting, transmission electron microscopy, and Bungarotoxin staining were used. BJIGT improved motor function and extended the survival duration of hSOD1G93A mice. In addition, BJIGT had protective effects, including anti-oxidative and anti-inflammatory effects, in both the spinal cord and muscle of hSOD1G93A mice. Our results demonstrated that BJIGT causes muscle atrophy and the denervation of neuromuscular junctions in the gastrocnemius of hSOD1G93A mice. The components of BJIGT may alleviate the symptoms of ALS via different mechanisms, and accordingly, BJIGT treatment may be an effective therapeutic approach.

Abstract
CONTEXT Icaritin (ICT), an intestinal metabolite of prenylflavonoids from Herba Epimedii, has been known to regulate many immune processes. But there are little studies of ICT on hematopoietic function. OBJECTIVE We aimed to investigate the improvement of ICT on hematopoietic function in cyclophosphamide (CTX)-induced myelosuppression mice. METHODS Mice were given CTX (50 mg/kg) by i.p. for five days to produce bone marrow depression model. 48 h after last treated with CTX, ICT was administrated at 10 mg/kg/d by p.o. for five days. Blood routine, body weight, thymus index and spleen index were tested. The bone marrow hematopoietic stem cells (HSCs) and hematopoietic progenitor cells (HPCs), cell cycle and apoptosis of HSCs were quantified by flow cytometry. The bone marrow nucleated cells were counted by an automated cell counter. The histology of femoral bone was examined by Haemotoxylin and Eosin (H&E) staining. Serum erythropoietin (EPO), granulocyte colony-stimulating factor (G-CSF) and thyroperoxidase (TPO) were tested by ELISA kit. RESULTS ICT (10 mg/kg) protected against CTX-induced myelosuppression, is evidenced by increased blood cell numbers, body weight, thymus index, spleen index and improved femoral bone morphology. ICT corrected the reduction of bone marrow HSCs and HPCs, promoted bone marrow HSCs entering the proliferative cycle phase and prevented cells proceeding to the apoptosis phase. Meanwhile, ICT increased the release of G-CSF and TPO in model mice serum. CONCLUSION These results demonstrated that ICT improves myelosuppression by improving bone marrow hematopoietic microenvironment, promoting the proliferation and differentiation of HSCs, inhibiting the apoptosis of HSCs and stimulating the expression of G-CSF and TPO.

Abstract
β-Glucans, glucose polymers that are the main constituents of the outer cell walls of micro-organisms such as fungi and yeast, are known to play an immunostimulatory role. We prepared β-glucan (β-(1-3),(1-6)-D-glucan) from an edible cultured fungus through fermentation techniques using a strain of Aureobasidium pullulans ADK-34. The purity of this β-glucan preparation (AP-FBG) was demonstrated to be high through various instrumental analyses. We then examined the effects of AP-FBG on intestinal immune systems. We prepared Peyer's patch (PP) cells and measured interleukin (IL)-5, IL-6, and IgA production in culture media with AP-FBG. We found that both cytokines and IgA increased; furthermore, IL-6 secreted by PP dendritic cells (PPDCs) cultured in the presence of AP-FBG significantly increased. We tested IgA production after oral administration of AP-FBG for 2 weeks and found that AP-FBG tended to promote the production of IgA in the small intestine. Interestingly, we observed a significant increase in IgA production in the small intestines of mice treated with cyclophosphamide (CY; an immunosuppressant) after oral administration of AP-FBG diet compared with CY-treated and control diet mice. Production of IL-6 and IgA by PP cells and IL-6 production by PPDCs in AP-FBG-fed and CY-treated mice also increased. These results demonstrate that AP-FBG has the ability to activate PPDC and induce IL-6 production and IgA secretion in PP cells. These abilities were more clearly expressed when AP-FBG was orally administered in a CY-induced immunosuppressed condition. Therefore, AP-FBG may be a useful ingredient for preparing functional foods with immunomodulatory activities.

Abstract
We evaluated the immunological effects of a Kampo (Chinese) prescription Hochu-ekki-to (TJ-41) for 32 weeks and 1 week prophylactically in mice. The splenic natural killer cells (NK) of C57BL/6N mice prophylactically treated with TJ-41 for 32 weeks showed little enhanced cytotoxicity against NK-sensitive YAC-1 targets, but mice treated for 1 week showed significantly enhanced cytotoxicity. TJ-41 administration for 32 weeks increased the splenic NK cell population and CD4/CD8 significantly, but TJ-41 for 1 week was not affected. Further, there were no adverse effects of TJ-41 administration for 32 weeks. Whether or not that duration of administration can have the same beneficial effects on humans await further studies.

Abstract
The body of tremella were decocted with water, and hydrolyzed with 0.1 mol/L hydrochloric acid for different times, giving tremella polysaccharides with six molecular mass values. The structures of all the tremella polysaccharides had non-reducing terminals of β-D-pyranglucuronide, the backbone was composed of (1 → 3)-linked β-D-manno-pyranoside, and the side chain composed of (1 → 6)-linked β-D-xylopyranoside was attached to the C(2) of the backbone mannopyranoside. Immunomodulatory effect studies indicated that tremella polysaccharides increased the counts of leukocytes in the peripheral blood which were significantly lowered by cyclophosphamide, and the lower the molecular mass of the tremella polysaccharide, the better this effect was.

Abstract
Chemotherapy is the most common way to treat malignancies, but myelosuppression, one of its common side-effects, is a formidable problem. The present study described the protective role of dammarane sapogenins (DS), an active fraction from oriental ginseng, on myelosuppression induced by cyclophosphamide (CP) in mice. DS was orally administered at different dosages (37.5, 75, and 150 mg/kg) for 10 d after CP administration (200 mg/kg intraperitoneally). The results showed that DS increased the number of white blood cells (WBC) on day 3 and day 7 (P < 0.05), such that WBC levels were increased by 105.7 ± 29.5% at 75 mg/kg of DS on day 3 (P < 0.05, compared with the CP group). Similar results were observed in red blood cells and platelets in DS-treated groups. The colony-forming assay demonstrated that the depressed numbers of CFU-GM (colony-forming unit-granulocyte and macrophage), CFU-E (colony-forming unit-erythroid), BFU-E (burst-forming unit-erythroid), CFU-Meg (colony-forming unit-megakaryocyte) and CFU-GEMM (colony-forming unit-granulocyte, -erythrocyte, -monocyte and -megakaryocyte) induced by CP were significantly reversed after DS treatment. Moreover, the ameliorative effect of DS on myelosuppression was also observed in the femur by hematoxylin/eosin staining. In DS-treated groups, ConA-induced splenocyte proliferation was enhanced significantly at all the doses (37.5, 75, 150 mg/kg) on day 3 at the rate of 50.3 ± 8.0%, 77.6 ± 8.5% and 44.5 ± 8.4%, respectively, while lipopolysaccharide-induced proliferation was increased mainly on day 7 (P < 0.01), with an increased rate of 39.8 ± 5.6%, 34.9 ± 6.6% and 38.3 ± 7.3%, respectively. The thymus index was also markedly increased by 70.4% and 36.6% at 75 mg/kg on days 3 and 7, respectively, as compared with the CP group. In summary, DS has a protective function against CP-induced myelosuppression. Its mechanism might be related to stimulating hematopoiesis recovery, as well as enhancing the immunological function.

Abstract
Ka-mi-kae-kyuk-tang (KMKKT) is an Oriental herbal medicinal cocktail and has been shown to have potent antiangiogenic, anticancer, and antimetastatic activities in preclinical animal models without observable side effects. We previously found that in prostate cancer xenograft experiments, treating tumor-bearing mice with KMKKT alleviated the body weight loss toward the end of the study, suggesting a general health-promoting activity. We investigated whether KMKKT alleviated cancer chemotherapy drug-induced leukopenia and other hematotoxicity in vivo using a mouse model. KMKKT was given once daily orally for 10 days to the mice before they were given cyclophosphamide (CPA) daily injection for 4 days. KMKKT blunted CPA-induced decrease in red blood cells, hemoglobin content, and the total white blood cell/leukocyte counts. Examination of the multiple organ sites involved in hematopoiesis, and lymphocyte differentiation and maturation showed the attenuated changes induced by CPA in each and every type of cells examined. Particularly, some of the cell types are fully restored in the bone marrow and even overstimulated in the Sca-1(+), CD117(+), or Sca1(+)/CD117(+) and CD34(+)/CD117(+) stem cells, supporting a role of KMKKT to stimulate hematopoietic stem cell (HSC) signaling to compensate for CPA-induced destruction of leukocytes and other cell types. Taken together, KMKKT might be a safe and effective herbal complementary and alternative medicine (CAM) modality to alleviate cancer drug-induced hematological side effects in addition to its anticancer activities. Preclinical investigations with other chemo- and radiation modalities are warranted to support planning translation consideration for human patients.

Abstract
Background Invasive aspergillosis (IA) is a major cause of infectious morbidity and mortality in immune compromised patients. Studies on the pathogenesis of IA have been limited by the difficulty to monitor disease progression in real-time. For real-time monitoring of the infection, we recently engineered a bioluminescent A. fumigatus strain. Results In this study, we demonstrate that bioluminescence imaging can track the progression of IA at different anatomic locations in a murine model of disease that recapitulates the natural route of infection. To define the temporal and functional requirements of distinct innate immune cellular subsets in host defense against respiratory A. fumigatus infection, we examined the development and progression of IA using bioluminescence imaging and histopathologic analysis in mice with four different types of pharmacologic or numeric defects in innate immune function that target resident and recruited phagocyte subsets. While bioluminescence imaging can track the progression and location of invasive disease in vivo, signals can be attenuated by severe inflammation and associated tissue hypoxia. However, especially under non-inflammatory conditions, such as cyclophosphamide treatment, an increasing bioluminescence signal reflects the increasing biomass of alive fungal cells. Conclusions Imaging studies allowed an in vivo correlation between the onset, peak, and kinetics of hyphal tissue invasion from the lung under conditions of functional or numeric inactivation of phagocytes and sheds light on the germination speed of conidia under the different immunosuppression regimens. Conditions of high inflammation -either mediated by neutrophil influx under corticosteroid treatment or by monocytes recruited during antibody-mediated depletion of neutrophils- were associated with rapid conidial germination and caused an early rise in bioluminescence post-infection. In contrast, 80% alveolar macrophage depletion failed to trigger a bioluminescent signal, consistent with the notion that neutrophil recruitment is essential for early host defense, while alveolar macrophage depletion can be functionally compensated.

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
The immune system plays an important role in protection against infection and in the maintenance of the internal environment of the body. However, such important immune functions are known to decline with age in many mammals, including humans. It is a matter of clinical importance that the incidence of various age-associated diseases such as infections, cancer and vascular disorders increases with a decrease in immunological vigor. The extent of immunologic decline is variable and exhibits wide inter-individual variations. Thus, it is important to assess the extent of immunologic decline in both patients suffering from various diseases and in healthy people in order to maintain healthy conditions. To this end, we have developed a scoring system that analyzes immune parameters according to a database of known age-associated immune changes obtained from a healthy population. Using this scoring system, we can combine several different immunological parameters and express the immune status of individuals as a simple numeral. After determining immunological vigor for individuals, it is necessary to replenish immune defects and restore them to normalcy for individuals with depressed immunological scores. This chapter provides methods of immunological restoration in animal models and introduces some similar attempts in humans. The effect of any immunological restoration varies with the individual and must therefore verified. Currently, the proposed immune scoring system proposed is useful to determine whether the methods employed are effective for the restoration of immune functions.

Abstract
BACKGROUND Bilioenterostomy is a common surgical technique that is widely used. Recently, clinical studies have revealed that biliary carcinomas can occur after bilioenterostomy. The present study was designed to evaluate whether hochu-ekki-to (TJ-41), a Japanese herbal drug, could prevent chemically induced biliary carcinomas in bilioenterostomized hamsters. MATERIALS AND METHODS Syrian golden hamsters were subjected to choledochojejunostomy and then received subcutaneous injections of N-nitrosobis(2-oxopropyl) amine every 2 weeks at a dose of 10 mg/kg. N-nitrosobis(2-oxopropyl) amine administration was started 4 weeks after surgery. The animals were simultaneously p.o. administered TJ-41 in water every day at a dose of 1000 mg/kg (TJ-41 group). The control hamsters were administered water alone. The hamsters were sacrificed 22 weeks after surgery, and the development of biliary carcinomas, the presence and degree of cholangitis, and the cell kinetic status of the biliary epithelium were evaluated histologically. RESULTS Intrahepatic bile duct carcinomas developed in 15/17 (88%) hamsters in the control group and in only 8/17 (47%) hamsters in the TJ-41 group (P < 0.05). The degree of cholangitis was not different between the two groups. However, the proliferating cell nuclear antigen labeling index of the biliary epithelium in the TJ-41 group (6.46%) was significantly lower than the controls (9.67%) (P < 0.05). These findings indicated that TJ-41 reduced accelerated biliary epithelial cell kinetics after bilioenterostomy, resulting in the prevention of carcinogenesis. CONCLUSION TJ-41 has a preventive effect on chemically induced carcinoma of the biliary tract after bilioenterostomy.

Abstract
The objective of the present studies was to investigate whether millimeter wave (MMW) therapy can increase the efficacy of cyclophosphamide (CPA), a commonly used anti-cancer drug. The effect of combined MMW-CPA treatment on melanoma growth was compared to CPA treatment alone in a murine model. MMWs were produced with a Russian made YAV-1 generator. The device produced 42.2 +/- 0.2 GHz modulated wave radiation through a 10 x 20 mm rectangular output horn. The animals, SKH-1 hairless female mice, were irradiated on the nasal area. Peak SAR and incident power density were measured as 730 +/- 100 W/kg and 36.5 +/- 5 mW/cm2, respectively. The maximum skin surface temperature elevation measured at the end of 30 min irradiation was 1.5 degrees C. B16F10 melanoma cells (0.2 x 10(6)) were implanted subcutaneously into the left flank of mice on day 1 of the experiment. On days 4-8, CPA was administered intraperitoneally (30 mg/kg/day). MMW irradiation was applied concurrently with, prior to or following CPA administration. A significant reduction (P < .05) in tumor growth was observed with CPA treatment, but MMW irradiation did not provide additional therapeutic benefit as compared to CPA alone. Similar results were obtained when MMW irradiation was applied both prior to and following CPA treatment.

Abstract
The object of this study was to investigate the efficacy of (+)-catechin, which was isolated from Actinidia arguta Planch (Actinidiaceae), as a bone marrow cell proliferation-promoting compound against the hematotoxicity of 5-fluorouracil (5-FU) in mice. Intraperitoneally injected (+)-catechin (1 and 10 mg/kg per day) accelerated the recovery of the number of white blood cells (WBC) and platelets (PLT) but did not affect the number of circulating red blood cells (RBC). (+)-Catechin also augmented the number of myelocytes and splenocytes. Dual color flow cytometric analysis revealed that (+)-catechin reversed the reduction of the population of leukocytes (CD11b+ monocytes, Gr-1+ granulocytes and CD3+ T and CD45RA+ B lymphocytes) in whole blood, spleen and bone marrow caused by 5-FU. (+)-Catechin (1 and 10 mg/kg per day) showed remarkable recovery of Gr-1+ cells in all three types of tissues and of CD11b+ cells in the bone marrow cells. These findings suggest that (+)-catechin selectively enhances the recovery of the population of granulocytes reduced by 5-FU in mice.

Abstract
The 'Yang'-promoting traditional Chinese medicines (TCM) are used to boost vigor and enhance immunity in humans. In this study, the immunopotentiating effect of VI-28, a 'Yang'-promoting TCM formula containing extracts of radix ginseng, cornu Cervi pantotrichum and radix Salvia miltiorrhizae, was investigated. Groups of 8-month-old female ex-breeder BALB/c mice were fed on ordinary mouse food or food containing a low (0.5%) or high (2%) dose VI-28 for up to 18 weeks. From week 6, mice on the TCM-containing diet were much healthier, stronger and more alert than those on the normal mouse food. Furthermore, their thymuses were significantly bigger and heavier than those of the control mice. Histological examination revealed structural changes typical of thymic involution in mice of the control group, whilst the microstructure of thymuses from mice taking TCM-containing food was comparable to that of mice of a much younger age, indicating a positive effect of VI-28 on slowing down thymic involution. Functional analysis of splenocytes from mice of different groups suggested that oral administration of VI-28 corrected the hyporesponsiveness of T lymphocytes in aged mice. These results have important implications for our understanding of the mechanisms of the immunoboosting effect of TCM.

Abstract
Dang-Gui-Bu-Xai-Tang (DGBXT), which includes Radix Angelicae Sinensis and Radix Astragali Membranaceus, is a traditional Chinese medicine used to modulate the lymphocyte activity of cancer patients after chemotherapy and radiotherapy. In the present study, we examined the cytotoxicity of DGBXT on transformed cells and the immunomodulating effects of DGBXT in a tumor-bearing murine model. DGBXT markedly inhibited the growth of the EJ-Ha-ras transformed LZEJ and LZEJ-C2 cells lines. Oral administration of DGBXT for three weeks significantly prevented the tumor development in mice that injected with LZEJ-C2 cells subcutaneously. Moreover, DGBXT effectively increased the population of cytotoxic T lymphocytes (CTLs) and NK cells, and down-regulated activated T helper cells (CD4+/CD25+) in spleen and tumor-draining lymph nodes (TDLN). Furthermore, DGBXT stimulated the production of tumor necrosis factor-alpha in in vitro cultured splenocytes. These results might explain the antitumor effects of DGBXT.

Abstract
This paper presents our long-term (1992-2000) treatment of pediatric Acquired Immune Deficiency Syndrome (AIDS) patients (maximum 100 children, last three years 65) using native herbal remedies in a voluntary medical assistance program in Constanta, Romania. We primarily report the progress of 10 children at a facility called the "House of Tomorrow" and three other facilities. The long-term (8 years and 8 months) treatment contributed to a drop of the amount of Human Immunodeficiency Virus Ribonucleic Acids (HIV-RNA) below the measurable level for 9 out of 10 patients at the "House of Tomorrow." Furthermore, the treatment led to preservation and increase of the cluster of differentiation (CD4) count, a remarkable decrease in mortality rate, as well as the maintenance of a good quality of life. It took one to three years for the beneficial effects of the treatment to emerge. No side-effects were recognized either clinically or biochemically, nor was there any emergence of drug-resistant strains of HIV as seen with anti-HIV chemical treatments. This paper also refers to which herbal remedies were used and their general mechanism of action.

Abstract
Autopsy reports by pathologists in geriatric hospitals reveal that the leading direct cause of death in the elderly over 65 years of age are infectious diseases such as pneumonia and urinary tract infection, neither cancer nor vascular diseases in the brain and heart. This indicates that severe impairment of immune functions is developing in the elderly people. The impairment of immune functions does not occur abruptly in the elderly people. The immune function starts to decline as early as at the 2nd decades, showing approximately 50 and 90% decline at the 5th and 8th decades, respectively. Thus, immunological restoration is acutely needed for the improvement of their general health condition of the elderly. This report communicates several methods of immunological restoration using animal models and suggests possibilities of human application. Methods presented are: (1) a low dose of cyclophosphamide; (2) vitamin E; (3) Japanese herbal medicines; (4) caloric restriction and exercise; (5) vaccine; (6) oral administration of antigens; (7) grafting of cells and tissues, including a future program. Discussion will be made on the possibilities of these methods for human application.

Abstract
In this study, the effect of traditional Japanese (Chinese) medicine, Hochu-ekki-to, HOT (Chinese name: Bu-zhong-yi-qi-tang), on the susceptibility against Listeria monocytogenes in postneonatal infant mice was examined. Numbers of bacteria in infant mice (infected at 4 weeks of age) were significantly higher than those in adult mice (infected at 8 weeks of age) on day 3 (non-specific resistance phase) and day 5 (specific resistance phase) after infection. Oral administration of 1,000 mg/kg of HOT for 7 days to infant mice reduced bacterial numbers in the liver and spleen at 5 days after the infection. The amount of IFN-gamma and the number of IFN-gamma-producing CD4+ T cells were lower in infant mice than adult mice but those in infant mice enhanced by HOT treatment. HOT also enhanced the antigen-presenting function along with the expression of MHC class II in infant macrophages induced by heat-killed L. monocytogenes. Further, HOT enhanced the IFN-gamma production from infant CD4+ T cells independent of the deficiency in the antigen-presenting function. These findings suggest that HOT induced simultaneously functional maturation of both infant antigen-presenting cells and T cells, and consequently developed an anti-listerial Th1 response.

Abstract
We examined the effect of two Japanese herbal medicines (Kampo-Hozai) on immunological functions and anti-tumor activity in old mice. Hochu-ekki-to (TJ-41) was remarkably effective in the restoration of impaired immune functions of old mice, in terms of number of T cells and NK cells, and anti-SRBC antibody response, while it was not effective in enhancing immune functions of young mice. Juzen-taiho-to was also effective in increasing the number of T cells, remarkably, and NK cells, slightly, in the aged mice. While a significant increase was not observed in young mice.
