  • The present study was undertaken to evaluate the effect of evening primrose oil (EPO) on the male sexual functions. EPO (daily 0.5 ml/mouse) was orally intubated for 28 consecutive days to experimental ICR mice, and same vol. of vehicle to control mice. On the 14th and 28th experimental day, the testis weight, number of complete intromissions and mating, serum testosterone and cGMP levels, prostaglandin leveIs of penile corpus cavernosum smooth muscle cells, and NO-productive activity of endothelial cells were determined. The weight of body and testis, the number of complete intromissions during the 3hour period were somewhat increased in EPO treated mice than those of control. The number of sperm-positive females and testosterone level in serum were increased in experimental groups. The serum cGMP level was significantly increased but the NO production of ionomycin-stimulated HUVEC cells was not affected when EPO was added into cultures. These results suggest that oral administration of EPO enhanced the sexual functions of male mice, and EPO could be developed as a tonic improving sexual functions.

  • Bisphenol A(BPA). a monomer used in the manufacturing epoxy resins and polycarbonates. has been reported to induce estrogenic activity, it has been considered as an environmental endocrine disruptor. But the immunomodulatory effects of BPA exposure have not been systemically evaluated. We investigated whether BPA effects on the ability of immunoglobulin(lg) production of mice. To initiate investigation of BPA-induced alterations of the immune system. BPA at dose of 100. 500,1000 mg/kg b.w./day with or without OVA-antigen for 30 days were orally administered to female ICR mice. Mice were sacrificed and serum was colleted on day 2 following administration of BPA for 30days. Total lgG1. total lgG2a. total lgE. OVA-specific lgG1. OVA-specific lgG2a. and OVA-specific lgE in serum were detetmined and compared with those of non-treated mice. In the groups of BPA with OVA antigen, total 1gG1, total lgG2a, total lgE. OVA-specific lgG1 and OVA-specific lgG2a were significantly decreased at dose of 500mg/kg/day. However, in mice treated with BPA alone, total lgG1, and lgG2 were not much altered and total lgE was significantly increased at dose of 1000mg/kg/day. These results demonstrated the BPA modulates the production of immunoglobulin.

  • This study was carried out to investigate the supplementary effects of the rice germ oil compared with soy bean oil on lipid metabolism of non-insulin dependent diabetic mice. Forty diabetic KK mice were fed two kinds of experimental diets with 20% lipid from soy bean oil as a control(CO) and rice germ oil(RG) for 8 weeks, respectively. Diet intake, body weight, organs weights and lipids levels of serum, liver and feces were measured. There was no significant difference in food and water intake, body weight gain and organs weights between experimental groups. But the concentrations of serum total cholesterol and LDL-cholesterol were lower in RG group than in CO group. The hepatic total lipid and total cholesterol levels of RG group were significantly lower than those of CO group. The contents of total lipid, triglyceride and total cholesterol excreted in feces of RG group were higher than those of CO group. These results suggested that rice germ oil can reduce serum total cholesterol and LDL-cholesterol and hepatic total lipid concentration of non-insulin dependent diabetic mice compared with soybean oil due to increasing fecal lipid excretion. But we need to investigate the hypolipidemic effect of this oil by supplementary level and period.

  • Objectives : In this study, we investigated the effect of Saposhnikoviae Radix on allergic responses in ovalbumin(OVA)-induced Allergic rhinitis(AR) mice. Methods : BALB/c mice were orally administrated with Saposhnikoviae Radix water extract (SRW, 50 mg/kg) or anti-histamine drug, Ketotifen (10 mg/kg) as a reference drug, followed by sensitization and challenge of OVA. Mice were measured clinical symptoms and the serum levels of histamine, IgE, IL-4, and IFN-${\gamma}$, and observed histopathological changes of nasal mucosa H&E staining. Results : SRW significantly decreased rubs and the serum levels of histamine, IgE, and IL-4, and then increased the serum levels of IFN-${\gamma}$ in OVA-induced AR mice, and inhibited histopathological changes of nasal mucosa with inflammation and the eosinophils infilteration. Conclusions : These data suggest that SRW has anti-allergic effect through the inhibitory property of Saposhnikoviae Radix against allergic responses in allergic rhinitis.

  • Effects of sosihotangganogyong on the activity of serum transferase and hepatic lipid peroxide in mice with $CCl_4$ solution were determined. The activity of ALT showed a high value in the mice with $CCl_4$, however in the mice with sosihotang and sosihotangganogyong, these values showed a tendency to rapid recovery compared with those of the mice with $CCl_4$ only and the activity of ALT in the group of sosihotang and sosihotangganogyong showed a low values compared with $CCl_4$ only group on the 21 days after treatment. On the 21 days after treatment, the activities of glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT) and lactic dehydrogenase (LDH) in the mice with sosihotang and sosihotangganogyog were similar to those of control group, however these values of $CCl_4$ only group showed a high values compared with those of other groups. The value of hepatic lipid peroxide in the mice with sosihotang and sosihotangganogyong showed a tendency to rapid decrease and recovery compared with those of $CCl_4$ only group and on the 21 days after treatment, this value showed a similar to those of control group. The activity of serum transferase and the value of hepatic lipid peroxide in the mice with sosihotngganogyong showed a tendency to decrease compared with those of sosihotang group, however these values showed a no significantly deference. Results from this study indicated that the sosihotagganogyong can effectively improve the recovery of liver function in mice with $CCl_4$.

  • Objectives : This study investigated the hepatoprotective effects effects of Jageum-jung extract on alcohol-induced liver disease mice model. Methods : Alcoholic liver disease was induced by Ethanol in C57/BL6 male mice, which were fed Lieber-DeCarli liquid diet containing ethanol. Jageum-jung (100,200 and 300 mg/kg bw/day) were orally administered daily in the alcoholic fatty liver disease mice for 16 days. Results : The results indicate that Jageum-jung promotes hepatoprotective effects by significantly reducing aspartate transaminase (AST) and alanine transaminase (ALT) levels as indicators of liver damage in the serum. Furthermore, Jageum-jung decreased accumulation of triglyceride and total cholesterol, increased levels of superoxide dismutase (SOD) and glutathione (GSH) in the serum of the alcoholic fatty liver disease mice model. Additionally, it improved the serum alcohol dehydrogenase (ADH) activity. Conclusions : This study confirmed the anti-oxidative and hangover elimination effects of Jageum-jung extract, and suggests the possibility of using Jageum-jung to treat alcholic liver disease.

  • The adjuvant effects of Korean mistletoe lectin-C (KML-C) were investigated following the oral administration of KML-C with ovalbumin (OVA) as an antigen. Mice were orally immunized with OVA alone or admixed with various doses of KML-C or cholera toxin (CT), and the titer of OVA-specific antibody in the serum and mucosal secretions were determined. OVA+KML-C-treated mice showed high titers of IgA specific to CT in mucosal secretions. The antibody titers in the serum of OVA+KML-C-treated mice were comparable to those in the serum of OVA+CT-treated mice. When mice were immunized with OVA+KML-C or with CT alone and subsequently injected with OVA on the footpads after the primary immunization, they showed a more significant increase in delayed-type hypersensitivity reactions than when they were administered CT alone. These results suggest that KML-C is a potent immunoadjuvant that enhances both humoral and cellular immunity by the mucosal immune system.

  • In order to investigate the effects of bisphenol A (BPA) on immune system in mice we examined the various immunological parameters. After single oral administration of BPA to female ICR mice, the weights of bodies and lymphoid organs, splenic cellularity and hematological parameters were examined on day 2 and 7. Among them WBC and splenic cellularity were slightly decreased on day 2. To assess the effects of BPA on humoral immune responses, splenic IgM plaque forming cell (PFC) and serum IgM were assayed. When BPA was administered after immunization with SRBC, but not before immunization, IgM PFC against SRBC was significantly lowered in a dose dependent manner. Serum IgM level was also decreased on day 4 when high dose (2000 mg/kg) of BPA was administrated after injection of OVA-antigen. The indexes of splenocyte proliferation (SP) to concanavalin A (Con A) and bacterial lipopolysaccharide (LPS) were measured in vitro by MTT assay. At low concentration BPA slightly increased splenocyte proliferation but at higher concentration it showed significant inhibitory effects on cell proliferation. Mitogen-stimulated SP was also determined with spleen cells from BPA treated mice. Con A-induced SP was slightly decreased and LPS-induced SP was especially inhibited at 1000 mg/kg and 2000 mg/kg of BPA. These results indicate that BPA is able to acutly evoke humoral and cell mediated immune suppression in mice.

  • Background: Atopic dermatitis (AD) is a common chronic inflammatory skin disease. To understand AD, there have been many trials establishing AD animal models. Although various trials to establish AD animal models have been existed, even the mechanisms of AD in animal models are not enough clarified. Objectives: This study assessed AD characteristics induced in Nishiki-nezumi Cinnamon/Nagoya (Nc/Nga) mice following trinitrochlorobenzene (TNCB) treatment for different periods and house dust mite (HDM) treatment to compare each model's immunological patterns, especially with cytokine antibody array tool. Methods: In this study, we exposed Nc/Nga mice to TNCB or HDM extract to induce AD. Nc/Nga mice were divided into 4 groups: control, TNCB 2 weeks-treated, TNCB 8 weeks-treated, and HDM-treated groups. After AD induction, all mice were evaluated by serum immunoglobulin E (IgE) concentration and serum cytokine antibody assays, scoring of skin lesions, scoring of scratching frequency, and histological analysis. Results: The results showed significant differences between groups in serum IgE concentration, skin lesion scores, and scratching frequency. The analysis results for serum cytokine antibody arrays showed that in the TNCB 8 weeks- and HDM-treated groups, but not in the TNCB 2 weeks-treated group, expressions of genes related to the immune response were enriched. Among the histological results, the skin lesions in the HDM-treated group were most similar to those of AD. Conclusions: We confirmed that immunological pattern of AD mice was markedly different between HDM and TNCB treated groups. In addition, the immunological pattern was quietly different dependent on TNCB treated duration.
