The purpose of this study is to prove the efficacy of KamiBohuh-tang(KBT) on immunoregulation and the possibility of KBT as an immunoadjuvant. KBT with solid feed was administered orally once a day for 7 days to an experimental group, a solution of salt and solid feed without KBT to a control group. After a week T cell, B cell, cytokines, nitric oxide and phagocytic activity are measured. KBT enhanced the proliferation of splenocytes and the subpopulation of Th cells in splenic T-Iymphocytes, but did not affect the proliferation of thymocytes. KBT decreased the subpopulation of T-Iymphocytes in splenocytes. KBT enhanced the production of interferon-γ. interleukin-2, interleukin-4 in mice serum and the phagocytic activity in peritoneal macrophages but it suppressed the production of nitric oxide. These results suggest that KBT is a potent prescription on immune response via the increase of the proliferation of splenocytes, the production of cytokines from splenic Th cells and the phagocytic activity in vivo.

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.

Purpose : The purpose of this research was to investigate the effects of Kamibojoongikkitang (KBT) on the immune cells in C57BL/6 mice. Methods : KBT (500mg/kg) was administerd p.o. once a day for 7 days. Results : KBT decreased the cell viability of thymocytes in vivo and in vitro system and decreased the cell viability of splenocytes in vivo, but increased the viability of splenocytes in vitro system. In addition, KBT did not affect the population of helper T (Th) cells and cytotoxic T (Tc) cells in thymocytes and decreased the population of T- and B-lymphocytes and the population of Th and Tc cells in splenocytes. Furthermore, KBT did not affect the production of ${\gamma}%-interferon and interleukin-4 in splenocytes. KBT increased the production of nitric oxide in vivo but decreased the production of nitric oxide in vitro system. KBT enhanced the phagocytic activity of peritoneal macrophages in vivo, but decreased the phagocytic activity in vitro. Conclusion : KBT has an inhibitory action on the specific immune response via decrease of the cell viability of thymocytes and splenocytes and has a potent action on the non-specific immunity via increase of phagocytic activity of peritoneal macrophages.

This study was conducted to evaluate the effect of inclusion of propolis extraction residue in the feed of broilers from 1 to 21 d of age on phagocytic activity of macrophages, cutaneous basophil hypersensitivity response to phytohemagglutinin, antibody production against Newcastle disease, lymphoid organ weight and hematological profile and to determine the optimal level of inclusion. 120 chicks, reared in metabolism cages until 21 days of age, were distributed in a completely randomized design, with five treatments (0%, 1%, 2%, 3%, and 4% of propolis residue) and six replications. The relative weight of thymus and monocyte percentage were affected by propolis residue, with a quadratic response (p<0.05) and lowest values estimated at 2.38% and 2.49%, respectively. Changes in relative weight of cloacal bursa and spleen, percentage of lymphocyte, heterophil, basophil, eosinophil, and heterophil:lymphocyte ratio, antibody production against Newcastle disease, phagocytic activity of macrophages and the average number of phagocytosed erythrocytes were not observed. The nitric oxide production with regard to positive control (macrophages+erythrocytes) decreased linearly (p<0.05) with increased doses of propolis residue. The remaining variables of nitric oxide production (negative control - macrophages, and difference between the controls) were not affected by propolis residue. The cutaneous basophil hypersensitivity response to phytohemagglutinin as determined by the increase in interdigital skin thickness exhibited a quadratic response (p<0.05), which predicted a lower reaction response at a dose of 2.60% of propolis residue and highest reaction response after 43.05 hours of phytohemagglutinin injection. The inclusion of 1% to 4% of propolis extraction residue in broiler diets from 1 to 21 days of age was not able to improve the immune parameters, despite the modest changes in the relative weight in thymus, blood monocyte percentage, nitric oxide concentration, and interdigital reaction to phytohemagglutinin.

To know the effects of Gentiana macrophylla(GM) on the immune response, this study was undertaken. GM is one of the well-known oriental medicines for a lomg time used for the treatment of such diseases as arthralgia, headache, hepatitis, SLE, hemiparesis, and so on. To evaluate the effects of GM on immune response in the collagen induced arthritis, phagocytic activity of macrophages, proliferation of T-lymphocytes, secretion of nitric oxide in urine, and production of ROIs, $TNF-{\alpha}$ and nitric oxide in synoviocytes were measured. The results obtained in this study were as follows: 1. During the progress of CIA, the administration of GM enhanced phagocytic activity of macrophages in vivo and vitro. 2. During the progress of CIA, the administration of GM inhibited production of ROIs in synoviocytes. 3. During the progress of CIA, the administration of GM inhibited production of TNF- a in synoviocytes. 4. During the progress of CIA, the administration of GM inhibited proliferation of T lymphocytes. 5. During the progress of CIA, the administration of GM inhibited production of nitric oxide in synoviocytes. 6. During the progress of CIA, the administration of GM inhibited secretion of nitric oxide in urine. According to the above results, during the progress of CIA, it might be considered that GM has a curative effect on rheumatoid arthritis by controling immune response.

This study were done to know the effects of Dangkiyeumja on the in vivo and in vitro immune responses of mice. The recipes of Dangkiyeumja used in this study enhanced such, cellular functions of immunocytes as phagocytic capacity of macrophages, rossett-eforming abilities of splenocytes and metabolic activities of lymphocytes, However, the same recipes decreased the formation of such reactive oxygen intermediates(ROI) as superoxide and hydrogenperoxide from the macrophages. The effects of the same recipes on the in vim immune responses was suppressive on the cellular immune response(CIR)measured by delayed-type hypersensitivity against dinitrofluorobenzene and mildly enhancing for the humoral immune response measured by antibody production against sheep red blood cells. The results of this study could be summarized as follow: 1. Administration of Dangkiyeumja enhanced the phagocytic activity of the murine macrophage. 2. Administration of Dangkiyeumja decreased the formation of ROI in the murine macrophage 3. Administration of Dangkiyeumja increased the number of the splenic rotte forming cells in the mouse. 4. Administration of DangKiyeumja did not effect the antibody production against sheep red blood cells. 5. Administration of Dangkiyeumja depressed the delayed-type hypersenitivity against dinitrofluoro benzene in the mouse. The result of this study suggest that Dangkiyeumja could ameliorate the hypersensitivity reactions by reducing the formation of ROI and decreasing the CIR without affecting the other functions of immunocytes.

The effects of osmotic stress on the non-specific immune response of Nile tilapia, Oreochromis niloticus, were investigated. Osmoregulatory mechanism of tilapia has been studied, but less information is available about innate immune response of O. niloticus faced with hyperosmolality. Acute osmotic stress was elicited by transferring tilapia from freshwater (FW) to 24 psu seawater (SW). Non-specific immune parameters including lysozyme activities of plasma and head kidney (HK), alternative complement pathway (ACP) activity in plasma, phagocytic capacities of spleen and HK immune cells, and respiratory burst activity of immune cells in both HK and spleen were analyzed. Lysozyme activities were increased at 1 h and 30 h after transfer to SW, but decreased at 10 h after SW transfer. Conversely, ACP activity increased 10 h after SW transfer. Phagocytic capacity increased slightly at 1 h and 5 h after SW transfer, and respiratory burst activity showed an increase in superoxide release at 10 h after SW transfer. Taken together, these results indicate that the exposure of tilapia to hyperosmotic conditions has immunostimulatory effects on cellular and humoral immune reactions.

Inhibitory effects of cockle extracts on carcinogen-induced cytotoxicity in C3H/10T1/2 cells were studied. Soup (62$\mu\textrm{g}$/mL), solubility (28$\mu\textrm{g}$/mL) and liposolubility (9 $\mu\textrm{g}$/mL) of the cockle inhibited 3-methyl-cholanthrene(MCA)-induced cytotoxicity in C3H/10T1/2 cells by 53 and 94%, respectively. These results suggest that the extracts cockle might have anticarcinogen-induced cytotoxicity of C3H/10T1/2 cells. The effects of cockle extracts on the immune response related to its antitumor activity in vitro and in vivo were investigated. The cockle extracts showed a direct cytotoxic effect on sarcoma-180 cells, tumor cells in vitro. Soup (0.49 mg/mL), solubility (0.11 mg/mL) and liposolubiliy (0.05 mg/mL) of the cockle markedly decreased the total numbers of sarcoma-180 cells, but not their viability. The phagocytic acitivity of peritoneal macrophage of mice was significantly augmented by these extracts of the cockle compared with that of control in vivo. These extracts also raised the phagocuytic index, indicating that the number of phagocytize dmicrobes per macrophage increased. Thus, cockle extracts might show a antitumor activity by enhancing the phagocytic cell activities.

Experiments were performed to investigate the effect of Panax ginseng petroleum ether fraction on delayed type hypersensitivity, rosette formation, phagocytic activity and histophathological influence in lead acetate treated mice. Lead acetate was administered in the drinking water and ginseng pet. ether fraction was injected i.p.. Mice were sensitized and challenged with sheep red blood cells. Erythrocyte(I) rosette formation and DTH reaction were significantly depressed in lead acetate treated mice, and those were restored administration of ginseng fraction. Ginseng pet. ether fraction administration did not have any effect on decreased phagocytic activity. Follicular and parafollicular areal destruction of spleen, and destruction of thymus were finded in lead acetate exposed-mice. Small dose of ginseng pet. ether fraction (5 mg/kg, 10 mg/kg), administraction inhibited those histopathological changes, but large dose (20 mg/kg) didn't.
