  • In order to evaluate the effects of the cell-mediated immunity of the animal in the chronic diseases the guinea pigs and rabbits were inoculated with Mycobacterium bovis. After 6 weeks these animals were sensitized and challenged with 2,4-dinitrochlorobenzene. The cutaneous reactions observed in these animal species were similar each other. Macroscopic and microscopic responses in the animal experimentally infected with M. bovis were markedly reduced compared to those in the control animals. The results indicated that the cell-mediated immunity of the animals was depressed by infection of M. bovis.

  • Effects of quercetin on the specific and non-specific immune responses were studied in vivo. Quercetin at a dose of 2.5, 5, 10, 20 and 40 mg/kg were orally administered to ICR male mice once daily for 28 consecutive days. Cyclophosphamide was injected intraperitoneally to ICR mice with a single dose of 5 mg/kg 2 days before secondary immunization. Mice were sensitized and challenged with sheep red blood cells (S-RBC). Immune responses were evaluated by humoral and cellular immune reponses and non-specific immune response. The results of this study were summarized as followings; 1. Quercetin significantly decreased the body weight, and introduced the atrophy of liver, spleen and thymus gland dose-dependently, but increased the numbers of white blood cell. 2. Querectin significantly depressed the hemagglutination titer, Arthus reaction and hemolytic plaque forming cell. 3. Quercetin significantly depressed the delayed type hypersensitivity and rosette forming cell. 4. Quercetin at a dose of 2.5, 5 and 40 mg/kg significantly depressed phagocytic activity. 5. Quercetin at a dose of 10 and 20 mg/kg significantly increased natural killer cell activity.

  • The purpose of this research was to investigate effects of Bangpoongtongsungsan water extract(BTSE) on the immune reaction, anti-allergy action and anti-inflammatory action in BALB/c mice. The administration of BTSE (500mg/kg) enhanced the cell viability of thymocytes and the population of helper T cells in splenic T-lymphocytes. BTSE suppressed the production of nitric oxide, but enhanced the phagocytic activity in peritoneal macrophages. BTSE enhanced hemagglutination titer in mice. BTSE inhibited passive cutaneous anaphylaxis induced by egg albumin in rat, the lethal anaphylaxis induced by platelet activating factor and compound 48/80 in mice, and then inhibited the degranulation of peritoneal mast cells induced by compound 48/80. BTSE did not inhibit Arthus reaction, but inhibited the delayed type hypersensitivity induced by SRBC and contact dermatitis induced by DNFB. BTSE inhibited the acute hind paw edema induced by histamine after 30 minutes, the permeability of evans blue into peritoneal cavity induced by acetic acid and the writhing syndrome induced by acetic acid. These results suggest that BTSE has an immunopotentiative action, anti-allergy action and anti-inflammatory action via the inhibition of histamine release.

  • In order to investigate the effects of shipjuntaepotang (少陰人 十全大補湯) on immune response, the author performed this experimental study. Delayed type hypersensitivity (DTH) and rosette forming cells (RFC) for cell-mediated immune response, hemagglutinin (HA) titers, hemolysin (HL) titers, and carbon clearance for phagocytic function of MPS (mononuclear phagocyte system) were measured in ICR mice. The results were summarized as follows. 1. DTH in the experimental group was increased, as compared with the control group, with statistical significance. 2. RFC in the experimental group was increased, as compared with the control group, with statistical significance. 3. HA-titers were increased in the experimental group, as compared with the control group, with statistical significance. 4. HL-titers were increased in the experimental group, as compared with the control group, with statistical significance. 5. Carbon clearance was increased in the experimental group, as compared with the control group, with statistical significance. Through invivo experimental study in ICR mice, these findings suggest that shipjuntaepo-tang enhance both cellmediated and humoral immune responce.

  • Antitumor effect of LC43, a protein-bound ploysaccharide (M.W. 43 kDa) that was purified from intergeneric protoplast fusant of Lentinus edodes and Coriolus versicolor, was elucidated against mouse sarcoma 180 cell in vitro and in vivo. By injecting LC43 into ICR mice bearing solid or ascitic sarcoma 180, tumor regression and survival rates were investigated. To examine the effects of LC43 on immunopotentiation activity. immunoorgan weight, B cell differentiation, T cell activity and macrophage activation were determined. LC43 showed antitumor effects against both solid tumor and ascitic tumor of sarcoma 180. It did not change significantly the immunoorgan weight but potentiated immune responses such as B cell differentiation and the release of superoxide anion from macrophages. These results suggest that the protein-bound polysaccharide of LC43 exhibited antitumor activities through the activation of immune-related cells and acted as an immunmodulator.

  • The polysaccharide fractions were isolated and purified from Phellodendron chinese SCHNEID, and antitumor activities using the melanoma B-16-derived metastatic tumors were examined at dosages of 2, 5 and 10 mg/100 g. F-7 and F-8 showed the highest tumor metastatic inhibitory activities (inhibition ratio 60 and 80% in 2 mg/100 g), and in dose of 5 mg/100 g, the inhibitory ratios were 85 and 70%, respectively. Furthermore, 10 mg/100 g of intraperitoneal (i.p.) injection gave 90 and 95% of inhibition. When the effects of polysaccharides on hypersensitivity were examined, the inhibitory activities were not markedly observed in oral administration, indicating that the polysaccharides are directly acting to immune system. Also, the polysaccharides increased the number of circulating blood leukocytes and total peritoneal exudate cells. Although implantation of tumor cells greatly decreased the productivity of antibody (antibody-mediated) and T lymphocyte reactivity (delayed-type) as 6.3 from 9.3 and 5.9 from 7.7, represented by the increase of footpad thickness, respectively. the polysaccharides elevated the reactivity of T lymphocyte in tumor-bearing mice, which were rapidly recovered by discontinuance of sample treatments. Especially, F-2, F-5, F-7 and F-8 remarkably recovered the decreased sensitivity. These results clearly indicated that the i.p. injection is much effective to suppress tumor growth than oral administration.

  • The purpose of this study was to evaluate the effects of several types of bibimbab (a Korean traditional meal of mixed rice with assorted vegetables), on various immune activities. Compared to control animals in a mouse model (given hamburgers), the oral administration of a portion of bibimbab containing wild plants significantly increased splenic B/T, thymic Th lymphocyte subpopulations, serum IFN-${\gamma}$ production, and enhanced hemagglutination titers up to 300%. Also, a consumption of mushroom-bulgogi bibimbab and Jeonju-style bibimbab markedly decreased compound 48/80-induced systemic anaphylaxis (immediate hypersensitivity), while bibimbab with wild plants inhibited SRBC-induced delayed type hypersensitivity. These results suggest that bibimbab with wild plants both up-regulate on immune activities and have anti-allergenic properties.

  • In order to research the effects of Shipjundaebotang(SDT) and Orostachys Herba(OH) on anti-tumor and immune response, the author performed this experimental study. Experimental groups are divided into five groups, which are solid extract of Orostachys Herba by water(OHW), solid extract of Orostachys Herba by ethanol(OHE), solid extract of Shipjundaebotang (SDT), solid extract of Shipjundaebotang added by solid extract of Orostachys Herba by water(SDT+OHW) and solid extract of Shipjundaebotang added by solid extract of Orostachys Herba by ethanol (SDT+OHE). In these experimental studies, extension of survival days for anti-tumor effect was observed, and de layed type hypersensitivity and rosette forming cell for cell-mediated immune response, hemagglutinin titers and hemolysin titers for humeral immune response, spleenic natural killer cell activity and carbon clearance (K-index) in vitro were measured with mice. The result were summerized as follows: I. SDT, SDT+OHW and SDT+OHE treated groups were significantly recognized to extend the survival days of tumor bearing mice as compared with the control group. 2. Delayed type hypersensitivity was significantly increased in SDT, SDT+OHW and SDT+OHE treated groups as compared with control group. 3. Hemagglutinin titer was increasred in all sample groups as compared with control group, but not significantly. 4. Hemolysin titers was significantly increased in SDT, SDT+OHW and SDT+OHE treated groups as compared with control group, and SDT+OHE treated group showed the increasing effect with significance as compared with the other sample groups. 5. For the effect of roselle forming cell quantitation, SDT, SDT+OHW and SDT+OHE treated groups showed the increasing effect with significance as compared with control group. 6. Natural killer cell activity was significantly increased in SDT+OHW as compared with comrol group, but the other groups, except OHW and SDT+OHW treated groups, revealed the increasing effect as compared with control group, but the significance was not admitted. 7. For the effect of K-index(Carbon clearance), SDT, SDT+OHW and SDT+OHE treated groups showed the increas ing effect with significance as compared with control group. 8. The study didn't show that Orostachys herba had any significance with survival days, anti-tumor effect and immune re sponse.

  • 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%.
