  • To clarify the activating effects of Scolopendrae corpus on immunological function, its effect on primary and secondary antibodies production in mice of various ages was investigated. Scolopendrae corpus increased the number of both antibody producing cells(anti-IgM and anti-IgG producing plaque forming cells, PFC) and phagocytic activity of peritoneal macrophage. Futhermore, these phenomena were significantly increased with aging in mice. Scolopendrae corpus also increased natural killer cell activity concerning to cancer immunology. These results suggest that Scolopendrae corpus markedly increases the reduced activity in the elderly and activates the immune response in senescence mice.

  • To investigate mechanism of antineoplastic activities of the protein-polysaccharide fraction of Coriolus versicolor (Fr.) Quel., the mycelium of the fungus was grown in a liquid medium and was extracted with hot water. The extract was purified and used for examining its effects upon immune response in mice. The fraction was administered at a dose of 20mg/kg/day to ICR mice for five days. After ten days the mice were immunized by sheep red blood cells. The plaque-forming cells (PFC) in their spleen were increased in the treated mice. The number of PFC in case of the protein-removed polysaccharide was lower than that of the entire protein-­polysaccharide fraction of the fungus.

  • Effect of the butanol fraction of Astragali Radix (BFAR) on the humoral immune response were investigated in ICR mice. Mice were divided into 4 groups and BFAR at doses of 5,25 and 125 mg/kg were administered orally to mice daily for 3 weeks, and the normal animals were given vehicle. The results of this study are summarized as follows; the relative weight of spleen was markedly increased by BFAR treatment, compared with that in normal mice. However, the body weight gain and the relative weight of liver were not affected. Splenic plaque forming cells and hemagglutination titers to sheep red blood cells, and the secondary IgG antibody response to bovine serum albumin were also dose-dependently enhanced by BFAR treatment. In these mice, BFAR did not increase serum alanine aminotransferase total protein, sect albumin and albumin/globulin ratio when compared with those in normal mice. Thus, these findings indicate that BFAR significantly enhances humoral immune response to antigen in concentrations that do not affected liver function.

  • In order to investigate the effects of api-toxin therapy on depression of immune response, mice were exposed to cold stress $(-20^{\circ}C)$) in 30 minutes twice a day and api-toxin(Bee Venom from Korea and U.S.A) therapy was treated to the Kihae $(CV_6)$ locus of human body every two days with 4 sessions of treatment for 8 days. The mice were sensitized i.v. with $5{\times}10^8$ sheep red blood cells (SRBC) on the 4th day and challenged i.d. with $2{\times}10^9$ SRBC 4 days later. Immune Response for delayed type hypersensitivity (DTH), lympocyte transformation(LTT), hemolysin titer(HL), plaque forming cells (PFC) were measured.

  • Many kinds of phenylpropanoids(PP), C6-C3 compounds, are widely distributed in many plants. In this experiments, effect of PP on sheep red bood cells (sRBC)-induced Arthus reaction (AR) were studied in ICR male mice. SRBC were challenged by i.p. injection two weeks after sensitization of Lp. injection of sRBC. Five days after the challenge of antigen, paw edema induced 3 hours after the last challenge by AR.

  • These experiments were conducted to investigate the effects of Glycyrrhizae Radix extract(GR) on histamine synthesis, lymphocyte blastogenesis in C57BL/6J mice splenocytes, IL-1 production, $Ca^{2+}$ uptake by macrophage-like P388D$_{1}$ cells and plaque forming cell assay against SRBC. Histamine contents, lymphocyte blastogenesis, IL-1 activity, $Ca^{2+}$ uptake and plaque forming cell were determined by enzyme isotope method, [$^{3}$H]-thymidine incorporation, C3H/HeJ mouse thymocytes proliferation, the addition of 5 $\mu$Ci/ml $^{45}Ca^{2+}$ to P388D$_{1}$ cell suspension and assay to sheep red blood cell, respectively. Cytotoxicity, which was expressed as 50% mortality, was occurred by the addition of GR(10$^{-3}$g/ml). Histamine production in mouse spleen cell culture was significantly increased by 48 hour incubation added 0.25$\mu\textrm{g}$/ml of Con A. Con A-dependent T-lymphocyte proliferation was also enhanced by the addition of 0.25 $\mu\textrm{g}$/ml of Con A. GR depressed histamine contents at 10$^{-9}$~10$^{-4}$g/ml. and Con A (0.25 $\mu\textrm{g}$/ml) dependent T-lymphocyte proliferation at 10$^{-5}$~10$^{-4}$g/ml. IL-1 activity was significantly decreased by 10$^{-8}$~10$^{-4}$g/ml of GR. $Ca^{2+}$ uptake was not changed by GR, but antibody production markedly increased at 10.0~50.0 mg/kg of GR. From the above results, it is suggested that GR have immuno-regulatory action; GR decreased cell-mediated immune response and increased antibody production by B lymphocyte at high doses.

  • To examine effects on complement and reticuloendothelial system, alkali extract was isolated from cultured mycelium of Ganoderma lucidum IY107. It was shown to strongly activate both classical and alternative pathways of complement as compared with krestin. Activated complement C3, 3rd peak, was observed by crossed immunoelectrophoresis. It was also shown to activate reticuloendotherial system of ICR mice in the carbon clearance test and to increase hemolytic plaque forming cells of the spleen. Carbohydrate and protein contents of the alkali extract were 10% and 49%, respectively. The carbohydrate consisted of four monosaccharides and the protein contained 16 amino acids.

  • Hot red pepper(Capsicum annum L.) has been extensively used as a spicy food additive and preservative in Korea. In this study, we investigated the effect of dietary hot red pepper powder on humoral immune response in rats. Sprague-Dawley rats were divided into 4 groups and fed experimental diets containing 0, 2, 5, 10% hot red pepper powder for 27 days. All groups were immunized with sheep red blood cells. In order to measure the immune response, plaque-forming cell number, agglutination titer, and serum antibody level were measured. Tissue ascorbic acid contents were also determined by high-performance liquid chromatogrphy. There was an increased plaque-forming cell number, agglutination titer, and serum IgG level in the groups supplemented with hot red pepper powder as compared to control. Tissure ascorbic acid contents in the hot pepper powder supplemented group were higher than those of control. The results suggest that the dietary hot red pepper powder enhances humoral immune response in rats, indicating that the hot pepper contains biological response modifier.

  • This study was conducted to investigate the immuno-regulatory effect and apoptosis of L1210 and HL60 leukemia cells of methanol-extracts of Cornus kousa Burg(CKB). The proliferation of mouse splenocytes and thymocytes enhanced by the addition of $10\;{\mu}g/ml$ of CKB. CKB were administered p.o. once a day for 7 days in adult male BALB/c mice. CKB increased the splenic and thymic T lymphocytes, especially the number of $T_H$ cells markedly increased by the treatment of CKB. CKB treatment induced the apoptotic cell death in L1210 mouse leukemia and HL60 human leukemia cells. In addition, CKB also accelerated the phagocytic activity in peritoneal macrophages and increased the production of plaque forming cells. These results suggest that CKB have an various immuno-regulatory property.

  • The crude polysaccharide from Panax ginseng prepared by hot water extration and precipiation with ethanol was further fractionated into neutral and acidic fractions by DEAE- cellulose ion exchange chromatography. The chemical compositions were 85.0% carbohydrorate and 15.0% protein for the neutral fraction, and 28.4% carbohydrate, 10.0% protein and 29.0% uronic acid for the acidic fraction. The acidic fraction was more effective in increasing of the ratio of spleen to body weight, the number of antibody secreting cells to SRBC and phagocytic activity of reticuloendothelial system, as well as antitumor activity against the solid form of sarcoma 180 in ICR mice than the neutral fraction. All polysaccharide fractions were mitogenic to cultured spleen cells of C57BL/6 mice. However, FA was different from FN in the co-mitogenicities with lectin mitogens. Both crude and acidic fractions potentiated remarkably the mitogenic activity of PHA-P or LPS in dose-dependent manner but neutral fraction enhanced only that of LPS. Three polysaccharide fractions had no effect on that of Con A. These results suggest that the acidic fraction may stimulate B and Td cells as well as macrophages while the neutral fraction may simulate only B cells and macropages.
