The effect of subcutanecus injection of Corynebacterium parvum($700{\mu}g$) on cellular and humoral immune responses when given at various time relative to sheep red blood cell(SRBC) sensitization were studied by the evaluation of Arthus, delayed-type hypersensitivity(DTH), rosette forming cell, hemagglutinin and hemolysin reactions. Arthus reactivity(3 hours) developed in control mice and test mice pretreated with C. parvum 8 days prior to intravenous sensitization with SRBC were similar. However, there was slight depression of reactivity when C. parvum was given subcutaneoutly(s.c.) 4 or 2 days prior to SRBC sensitization. Arthus reactivity was significantly depressed when C. parvum was given s.c. either at the same time as, or 2 days later than, antigen. DTH reaction was net depressed significantly when C. parvum was injected 8 or 2 days prior to SRBC sensitization or at the same time as antigen. In contrast DTH was significantly augmented when C. parvum given s.c. 4 days prier to SRBC sensitization. DTH was depressed when C. parvum was given s.c. 2 days after antigen. No significant change occurred in rosette forming percetages of spleen cell when C. parvum was given s.c. 8, 4 or 2 days before SRBC sensitization. In contrast, a significant reduction in percentages of rosette forming cell occurred when C. parvum was given s.c. either at the same time as, or 2 days later than, antigen. Serum hemaggulutinin and hemolysin titers were not significantly affected by subcutaneous injection of C. parvum regardless of time relative to SRBC sensitization. However, mercaptoethanol-resistant hemaggulutinin and hemolysin(IgG) titers were somewhat augmented when C. parvum was given 2 days after antigen. It is concluded from these results that depending on the time and route of inoculation, C. parvum can enhance or depress immune responses in mice, suggesting the time and route of C. parvum inoculation is an important point of concern about clinical use of C. parvum for the treatment of cancer.

Objectives : Allergic contact dermatitis(ACD) is a type IV delayed hypersensitivity reaction that results from cumulative exposures and subsequent sensitization to an environmental chemical. Lonicerae Caulis(LC) can clear away heat and relieve toxin, disperse wind and heat, dredge the channel. The present study was designed to investigate the effects of LC on allergic contact dermatitis(ACD) induced by 2,4-dinitrochlorobenzene(DNCB) in mice. Methods : In this experiment, the effects of LC on changes in body weights, ear and dorsum skin thicknesses, ear weights, clinical aspects on the dorsum skin, histopathological changes, spleen/body ratio, cytokines were investigated. In addition, the effects on proliferations of splenocytes were also investigated in vitro and vivo study. Results : LC spread(SPR) group and LC spread and administered(SPR+ADM) group showed diminished ear thicknesses. In SPR+ADM group, ear weights were lowered significantly compared to contact dermatitis control(CTL) group. LC treatment diminished erythema, desquamation and keratosis which were induced by repeated painting of DNCB. In histopathological observation, spongiosis and edema were diminished in SPR and SPR+ADM group. In cytokines, SPR+ADM group were increased in IL-10, and SPR and SPR+ADM group were decreased in TNF-${\alpha}$ compared with control group. Conclusions : These data suggest that LC can decrease symptoms of ACD, then LC is useful to treat patient with ACD.

Inner nutshell of Castanea mollisima BL (chestnut) has been used as an anti-aging and anti-wrinkle agent from the ancient time in east Asia. In order to develop new anti-aging and anti-wrinkle, ethanolic extract of inner nutshell of Castanea mollisima BL (Cor-285) was prepared and various biological activities were evaluated. Cor-285 showed potent antioxidant activity, Especially, Cor-285 possessed potent free radical scavenging activity in vitro (IC50:7.6 g/ml) compared to gallic acid (IC50:12.5 g/ml), Cor-285 showed the preventive effect against UV-induced cytotoxicity of fibroblast at concentration of 25-250 g/ml. When Cor-285 was evaluated for its anti-allergic activity, it effectively inhibited histamine release from mast cells induced by compound 48/80 (86% inhibition at 10 mg/ml). The inhibitory activity was stronger than that of glycyrrhiznate. Cor-285 also showed in vivo inhibition against delayed hypersensitivity as well as croton-oil induced ear edema in mice when topically applied These results strongly suggest that Cor-285 may reduce immunoregulatory 1 inflammatory skin trouble. From the attempts to isolate the constituents, citropten (simple coumarin) and ellagic acid, a well known radical scavenger, were isolated. In a clinical trial of twenty healthy volunteers with aged skin,6 weeks application of Cor-285 (3% cream) decreased wrinkle about 26% and increased moisturizing 20% on the skin. All of these results indicate that Cor-285 may be an effective anti-aging and anti-wrinkle agent.

Phaseolus aureus (mung bean), Leguminosae, has been used as an antidote from the ancient time. Especially, it has been widely used for cleaning face and skin in oriental countries. Although several constituents such as fatty acids, phytoallexin and phaseol derivatives were reported in P. aureus and related species including seedlings, there has been a few report to describe its biological activity. Therefore, in this investigation, the ethanol extract from P. aureus was obtained and its biological activities including the antioxidative and anti-inflammatory activities were studied. The 70% ethanol extract from P. aureus showed dose-dependent antioxidative activity (52.3% inhibition at 4 mg/ml) against lipid peroxidation assay, while the extract did not show the inhibitory activity of superoxide radical formation. The extract also showed the topical anti-inflammatory activity against croton-oil and arachidonic acid induced mouse ear edema test (18-19% inhibition at 7.5 mg/ear) as well as mild inhibitory activity against picryl chloride induced delayed hypersensitivity in mouse. For investigating active principles, vitexin and isovitexin (apigenin C-glycoside) as flavonoids, and adenosine were isolated from the extract using silica gel chromatography. The actual contents of vitexin and isovitexin were found to be 3.7 and 2.4 mg/g extract, respectively. Vitexin and isovitexin showed the antioxidative activity. They showed the topical anti-inflammatory activity, although the activities were not potent compared to the reference compounds. These results suggested that vitexin and isovitexin may be, at least in part, the compounds contributing the antioxidative activity in vitro and the topical anti-inflammatory activity of P. aureus in vivo. All results of present study might be one of the scientific rationale in using mung bean for skin care from the ancient time.

The effects of cylindan, a polysaccharide isolated from the basidiocarps of Agrocybe cylindracea, on murine sarcoma 180 tumor and murine immune cells were examined after intraperitoneal administration. Cylindan exhibited a marked life extension effect in mice against ascite forms of sarcoma 180 and Lewis lung carcinoma at a dose of 50 mg/kg/day, although it did not show any direct cytotoxicity against sarcoma 180, X5563, and MM46 murine tumor cells. Cylindan increased numbers of bone marrow stem cells as well as peritoneal exudate cells in flow cytometry using monoclonal antibodies. The tumor bearing mice group apparently showed the increase of macrophages and cytotoxic T lymphocytes in mouse spleen cells during the early stage of tumor growth. But during the later stage, the control group decreased immune cells and cylindan restored the decreased immune cells in the tumor bearing mice to the normal level. In non-specific immune response, cylindan stimulated the bacterial phagocytosis and acid phosphatase production in macrophages. It also activated components of the alternative complement pathway and natural killer activity against YAC-1 lymphoma. In number of plasma cells as token of stimulation of the differentiation of B lymphocytes. In cellular immunity, cylindan restored the depressed response of delayed type hypersensitivity in the tumor bearing mice to 60% of the normal level and increased the interleukin-2 (IL-2) responsiveness in the IL-2 dependent CTLL-2 cells. These results suggest that cylindan did not show direct cytotoxic effects on tumor cells but restored the decreased immune response of the tumor bearing mice.

Effects of methanol extract of Astragali Radix (AR) on the immune responses were studied using ICR mice. Mice were divided into 4 groups (10mice/group), and methanol extracts of AR at doses of 0.05, 0.25 and 1.25g/kg were orally administered to ICR mice once a day for 2 weeks. Mice were immunized and challenged with sheep red blood cells (SRBC). The results of this study were summarized as follows; (1) Methanol extract of AR at 0.05, 0.25 and 1.25g/kg didn't affect the weight ratios of thymus to body, as compared with those in controls, but significantly increased spleen weight ratio. (2)Methanol extract of AR at 0.05 and 0.25g/kg significantly increased hemagglutination titer and splenic plaque forming cells corresponding to humoral immunity, as compared with those in controls, but their enhancements were somewhat lowered at a high dose (1.25g/kg). (3) Methanol extract of AR at 0.05 and 0.25g/kg siginificantly increased delayed-type hypersensitivity reaction resulted from cell-mediated immunity, as compared with those in controls, but not so significant increases were observed at a high dose (1.25g/kg). (4) Methanol extract of AR at 0.05 and 0.25g/kg significantly increased phagocytic activity and the number of circulating leukocyte compared with those in controls, but their enhancements were lowered at a high dose (1.25g/kg). These results suggest that methanol extract of Astragali Radix increased humoral and cell-mediated immune responses, phagocytic activity and the number of circulating leukocyte, dependent upon dose, but inhibited their enhancement effects were decreased at a high dose (1.25g/kg).
