The effect of vitamin A on the immune response in ICR mice was studied. The effects were evaluated by immuno organ weight, peripheral circulating white blood cells, HA and HY titer, peritoneal exudate cells, RFC, Arthus reaction and DTH in mice. The spleen of mice was significantly hypertrophied by deficiency or over doses of vitamin A as compared with control group (50IU/kg). Arthus reaction, RFC and peritoneal exudate cells were sharply decreased according to the increase of vitamin A doses. The number of white blood cell was decreased according to the increase of vitamin A doses, but in the case of vitamin A 50,000 IU/kg treated group, it was significantly increased. These results suggest that deficiency or over dose of vitamin A decrease humoral and cellular immune response.

The fractions of Epimedii Herba were examined for the immunological effects in ICR mice. Mice were divided into 4 groups and administered orally the fractions of Epimedii Herba for 10 days. The results of this study were summarized as following: (1) The fraction 1 (EtOAc layer) administered group as compared with control group significantly decreased spleen weight, Arthus reaction and hemagglutination (HA) titer but significantly increased circulating white blood cells (WBC). (2) The fraction 2 ($H_20$ layer) administered group as compared with control group significantly decreased liver weight, Arthus reaction and HA titer but significantly increased WBC. (3) The fraction 3 (ppt) administered group as compared with control group significantly increased liver weight, thymus weight rate, delayed type hypersensitivity, phagocytic activity and WBC. The results showed that Frs. 1 and 2 administered groups reduced humoral immune response but increased WBC, and that Fr. 3 administered group increased cell-mediated immune response, phagocytic activity and WBC.

Modulating effects of Candida albicans on the immune responses of mice immunized with sheep red blood cells(SRBC) were assessed both by footpad tests for anaphylactic, Arthus and delayed type hypersensitivity rections against homologous and heterologous antigenic challenges and by serum antibody titrations for hemagglutinin and hemolysin against SRBC. The results are summarized as follows: 1. In the mice simultaneously immunzed with C. albicans and SRBC, anaphylactic type and Arthus type footpad reactions to C. albicans challenge were enhanced, and extents of the enhancements were proportional to the concentration of SRBC administered for immunization, reaching peak in mice immunized with 0.2ml($10^8$) of 5% SRBC suspension. Although a little enhancement of delayed type hypersensitivity to C. albicans was observed in those mice, there was no significant difference between the mice groups immunized either with SRBC alone or SRBC and C. albicans simultaneously. 2. Simultaneous immunization of mice with C. albicans and SRBC resulted in the suppression of both anaphylactic type and Arthus type footpad reactions to SRBC, and the extent of such suppressions was inversly proportional to the numbers of C. albicans administered for immunization. Delayed type reaction of the mice to SRBC varied little in regards to the different numbers of C. albicans injected. 3. Hemagglutinin titers differed little between the mice groups immunized with SRBC alone or with SRBC and C. albicans simultaneously. Hewever, hemolysin titers were lower in the mice immunized simultaneously with SRBC and C. albicans. 4. In the peripheral blood of mice immunized simultaneously with SRBC and C. albicnas. there observed increases in the percents of monocyte and polymorphonuclear leukocytes and decrease in the numbers of lymphocytes and pyroninophilic lymphocytes. These results indicated that C. albicans is an immunosuppressant of the mice to SRBC when both anteigns were administered simultaneously for immunization, and that SRBC acted as an enhancer of anaphylactic type and Arthus type reaction of mice to C. albicans when administered simultaneously.

The effects of butylated hydroxyanisole and butylated hydroxytoluene on the immune status in normal male were evaluated. They exhibited significant decrease in the circulating leukocyte counts. Relative spleen and thymus weights were slightly decreased, but not stratistically significant. These were, however, significant liver hypertrophies in theier exposed mice. Splenic IgM PFCs per one million cells in 1/20 LD50 BHA and BHT exposed mice were significantly reduced IgM PFCs per spleen were similar tothose of control, except in 1/20 LD50 BHA exposed mice, where they were significantly suppressed. The precise nature of the inhibition is not clear. Direct cytotoxicity is not responsible for the depressed antibody response, even following relatively high doses of them, because the changes in spleen cellularity are not significant. Both substances, however, did not show any effects on the arthus reaction and delayed hypersensitivity reaction induced by heat aggreagted bovine serum albumin, and in vivo phagocytosis of colloidal carbon. In the light of the present results, in vivo antibody response as well as in vitro, may be sensitive to BHA of the present results, in vivo antibody response as well as in vitro, amy be sensitie to BHA and BHT. Further elucidation of the precise nature of antibody suppression in their exposed mice, is warranted.

Effects of beta-carotene on the immunobiological responses were studied in ICR mice. ICR male mice were divided into 8 groups (10 mice/group), and beta-carotene at doses of 4, 20 and 100 mg/kg were orally administered to ICR mice once daily for 28 consecutive days. Cyclophosphamide (CY) was injected intraperitoneally (i.p.) to ICR mice with a single dose of 5 mg/kg body weight at 2 days before secondary immunization. Mice were sensitized and challenged with sheep red blood cells (5-RBC). Immune responses were evaluated by humoral immunity, cellular immunity and non-specific immunity. The results of this study were summarized as follows: (1) Beta-carotene significantly increased the weight ratios of liver, spleen and thymus to body weight depending on dose, and significantly increased the increasing rate of body weight and the number of circulating leukocyte. (2) Beta-carotene dose-dependently increased hemagglutination titer, Arthus reaction and hemolytic plaque forming cell related to humoral immunity. (3) Beta-carotene significantly increased delayed-type hypersensitivity reaction and rosette forming cell related to cellular immunity. (4) Beta-carotene dose-dependently increased phagocytic activity, and significantly increased natural killer (NK) cell activity. (5) Beta-carotene dose-dependently inhibited reductions in humoral immunity, cellular immunity, NK cell activity and phagocytic activity by treatment with CY.

Effects of Zinc chloride on the immune responses were studied in ICR mice. ICR male mice were divided into 5 groups(10 mice/group) and Zinc chloride at doses of 0.3, 1.2, 4.8 and 19.2 mg/kg were orally administered to ICR male mice once a day for three weeks. Mice were sensitized and challenged with sheep red blood cells(S-RBC). The results of this study were summarized as follows; (1) Zinc chloride significantly increased the body weight rate, the weight ratios of spleen and thymus to body weight and the number of circulating leukocyte, but significantly decreased them at the high dose of it, and increased dose-dependently the weight ratio of liver to body weight. (2) Zinc chloride significantly increased hemagglutination titer, Arthus reaction and plaque forming cell related to humoral immunity, but significantly decreased them at the high dose of it. (3) Zinc chloride significantly increased delayed-type hypersensitivity reaction and rosette forming cell related to cellular immunity, but significantly decreased them at the high dose of it. (4) Zinc choride significantly enhanced phagocytic activity, but significantly decreased according to the increase of its dose. These results suggest that high dose of zinc chloride decreased humoral, cellular and non-specific immune responses.

Experiments were performed on mice to investigate the effect of methionine diets (MET) on the immunotoxicity of ethanol. ICR female mice were divided into 5 groups, Met (Basal (B)+0.19% methionine(M), B+1.71% M and B+5.13%W) and ethanol(4%) were administered ad libitum for 21 days. The mice were evaluated for changes in immune status as measured by antibody titer, Arthus reaction, delayed type hypersensitivity (DTH), rosette forming cell(RFC) and plaque forming cell (PFC) to sheep red blood cells (S-RBC). To investigate the change of the non-specific immune response, the number of leukocytes in peripheral blood and phagocyte activity were measured. The results were summarized as follows: (1) The weight ratios of spleen and thymus to body weight were significantly increased by the B+0.19% M, B+0.57% M and B+1.71% M groups in comparison with control group(B), but B+5.13% M group was significantly decreased. (2) Humoral immune responses were significantly increased by the B+0.19% M and B+0.57% M groups in comparison with control group, but B+5.13% M group was significantly decreased. (3) Cellular immune responses were significantly decreased by the B+1.71% M and B+5.13% M groups in comparison with control group. (4) Phagocyte activities were significantly increased by the B+0.19% M, B+0.57% M and B+1.71% M groups in comparison with control groups, but B+5.13% M group was significantly decreased. (5) The number of circulating leukocyte was significantly increased in the B+0.19% M and B+0.57% M groups in comparison with control group, but B+5.13% M group was significantly decreased.
