  • Experiment was performed to investigate the immunotoxicity of cadmium administered orally and the effect of ginseng petroleum ether fraction on it. Mice were given 3, 30, or 300 ppm cadmium as cadmium chloride orally in the drinking water and injection of ginseng petroleum ether fraction intraperitoneally for 4 weeks. Mice were sensitized and challenged u'ith sheep red blood cells (5-HBC). Immune response was evaluated by delayed type hypersensitivity (DTH), Rosette forming cell (RFC), phagocyte activity, and natural killer cell activity (NK cell activity). In the present study, cadmium suppressed the cellular immunity, It also depressed phagocyte activity very significantly in all cadmium-administered groups, NK cell activity in the cadmium-300 ppm administered group. Ginseng petroleum ether fraction showed restoring effect on the decrease in RFC by cadmium-administration. Remarkably, it showed very significant restoring effect on the depression of phagocyte activity induced by cadmium-administration. From this result, we suppose that the anti-tumor effect of ginseng ether or petroleum ether extract, which has been reported by some other researchers, is mainly due to the increase of phagocyte activity by it's administration.

  • To determine the effects of genetic and environmental influences on cell mediated immune (CMI) responses in broiler rabbits, contact sensitivity to 2,4-Dinitrochlorobenzene (DNCB) was assessed in three temperate broiler breeds of rabbits, namely Soviet Chinchilla, New Zealand White and Grey Giant. The feasibility of using the contact sensitivity to DNCB as a marker trait in selection for disease resistance was examined. There were highly significant differences between breeds (p<0.01) in initial skin thickness and contact sensitivities to DNCB at 24, 48 and 72 hours. Initial skin thickness was greatest in the Soviet Chinchilla breed (mean 2.2484 mm), and was significantly greater (p<0.01) in males (2.4963 mm) than in females (1.7846 mm) (p<0.01). Highest contact sensitivity to DNCB was in the New Zealand White breed with mean increase in skin thickness of 1.1884, 0.9072 and 0.5879 mm at 24, 48 and 72 hours post challenge respectively. Delayed type hypersensitivity (DTH) reaction to DNCB at 24 hours post challenge had a highly significant association (p<0.01) with the incidence of body mange in rabbits. The results indicated a lowered contact sensitivity to DNCB at 24 hours post challenge was associated significantly (p<0.01) with an increase in incidence and severity of body mange, suggesting its potential value as a marker. The correlation s among contact sensitivities at 24, 48 and 72 hours were positive and highly significant (p<0.01); correlations between initial skin thickness and contact sensitivities were negative and highly significant (p<0.01). Another notable significant correlation was between body weight and delayed type hypersensitivity at 24 hours indicating that an enhanced CMI might be associated with better growth rate and general wellbeing.

  • 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.

  • The purpose of this research was to investigate the effects of Kwakhyangjeonggisan (KJS) on the anti-allergic action. In the present study, we examined the effect of KJS on type I and type IV allergic reaction. KJS inhibited the systemic anaphylaxis induced by compound 48/80 and platelet activating factor (PAF), and inhibited the passive cutaneous anaphylaxis (PCA) induced by anti-dinitrophenyl (DNP)-IgE and DNP-human serum albumin (HSA) in vivo. In addition, KJS dose-dependently inhibited the release of histamine from peritoneal mast cells in rat. Also, KJS inhibited the delayed type hypersensitivity (DTH) induced by SRBC and the contact dermatitis induced by dinitrofluorobenzene (DNFB). KJS inhibited the proliferation of splenocytes, the subpopulation of B220+ cells and CD4+CD8-(Th) cells in splenocytes and the production of γ-interferon in serum and splenocytes. These findings suggest that KJS prevented the type I allergy by the inhibition of histamine release from mast cells and the type IV allergy by the inhibition of γ-interferon production and B lymphocytes subpopulation. These results indicate that KJS may be useful for the prevention and treatment of type I and type IV allergy related disease.

  • To investigate the preventive effects of melatonin (MLT) on the immunotoxicity of cadmium acetate[Cd(AC)2] in ICR mice, Mlt(10,50mg/kg as cadmium) were orally administered to mice once a day (5:00, PM) for 28 consecutive days. Cadmium(Cd) test solution was also administered at 25mg/kg of cadmium through the same route 2hr after administration of MLT daily, Mice were immunized and challenged with sheep red blood cells (SRBC). Immune functions evaluated were delayed type hypersensitivity (DTH) response, mitogenic response, and flow cytometry analysis. The results of these studies were summarized as follows ; DTH response was abnormally increased in mice treated with Cd alone. DTH response was normally depressed in mice treated with Cd plus MLT along with the increase of MLT doses. The mitogenic response of splenic T cell to Con A and that of B cells to LPS was remarkably increased by MLT treatment as compared with treatment of Cd alone In case of CD 8+ cells, the slight increase was observed in MLT treatment. Splenic T cells and B cells were significantly increased by MLT treatment as compared with treatment with Cd alone. These results suggest that MLT has significant preventive effects on the immunotoxic status induced by Cd exposure.

  • To determine contents of general constituents of Ganoderma lucidum in Korea, the dried carpophores were analyzed. The contents of water, ash, crude lipid, crude protein and crude cellulose were 14.6, 2.0, 3.3, 23.6, and 59.0%, respectively. Among reducing sugars, maltose was the most abundant. Seventeen free amino acids were detected, showing alanine the highest value. The pH of hot water extract was 4.1-4.2. The spores of Ganoderma lucidum was flat and ovoidal long. Their size was $6.3-7.1{\times}3.5-4.3{\times}2.0-2.5\;{\mu}m$ long. To examine effects of life span against sarcoma-180 cells, Fractions A, B and C, were obtained from the extract of Ganoderma lucidum. The survival rates of Fractions A, B and C were 131.7, 162.5, and 141.7 %, respectively. In addition, to examine effects of Fraction B on cell-mediated immunity, delayed type hypersensitivity (=DTH) test was conducted. It restored the suppressed DTH in the sarcoma-180 bearing group up to 66.7%.

  • This study was undertaken to assess the susceptibility of pigmented and nonpigmented strains of Serratia marcescens to antibiotics and human sera, and the effect of culture filtrates from pigmented and nonpigmented of Serratia marcescens on humoral and cellular immune responses in mice to thymus-dependent and indepependent antigens. Humoral immune response was measured by hemagglutinin (HA) and hemolysin (HE) to sheep red blood cell (SRBC), and Arthus or antibody response to polyvinylpyrrolidone (PVP). The cellular immune response was measured by delayed-type hypersensitivity (DTH) determined by footpad swelling reactin to SRBC. The resistance of pigmented strains of Serratia marcescens to the bactericidal action of heat inactivated human serum was insignificantly greater than that of nonpigmented strains. However, the pigmented strains were significantly more resistant to the bactericidal action of heat-untreated human serum than that of nonpigmented strains. The clinical isolates of Serratia marcestens was also tested for their resistance to several antibiotics. There was no difference between the pigmented and non-pigmented strains in the resistance to carbenicillin. However, nonpigmented strains were more resistant to gentamicin, kanamycin and tobramycin than the pigmented strains. The intraperitoneal administration of culture filtrates from the pigmented or nonpigmented strains into mice caused enhancemented of antibody response to SRBC or PVP, and of DTH to SRBC. Besides, their enhancement of immune responses was more prominent when culture filtrate from the pigmented strains was administered.
