In thymidine uptake assay, GHT showed the significant proliferating effect of splenic lymphocyte in proportion to the concentration. 3. In the expression of CD3e/CD4, CD3e/CD8, and B220 in peripheral blood mononuclea cells (PBMCs) of mice, GRT had no significant change to the normal group in CD4. However, GRT showed an increase to the normal group in CD8 and GHT in the only $1\mu\textrm{g}/ml$ category showed an increase to the normal group in B220. 4. In the cytotoxic effect of GRT on A549, SK-OY-3, SK-MEL-2 and MCF-7 cells, there was no significant cytotoxic effect compared to the control group. 5. In the inhibitory effect on the activity of DNA topoisomerase I, GHT in the $10\mu\textrm{g}/ml$ category showed the inhibitory effect on the activity of DNA topoisomerase I in proportion to the concentration. 6. In the T/C% in ICRmice bearing S-180, GHTtreated group showed 123.7% of T/C% compared to the control group. 7. In the inhibitory effect of cell adhesive of A549 Cells and SK-OV-3 Cells to complex extracellular matrix, GRT in the only $100\mu\textrm{g}/ml$ category showed the significant inhibitory effect compared to the control group. 8. In the inhibitory effect on lung colonies, GHT showed the significant inhibitory effect on lung colonies compared to the control group. 9. In the change of lung tissue, GHT showed a significant decrease of lung cancer growth, interalveolar fibrosis and hyaline material compared to the control group.

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.

Background: To investigate the role of sympathetic nervous system (SNS) in moxibustion-induced immunomodulation, the effects of chemical sympathectomy on moxibustion-induced changes in splenic NK cell cytotoxicity, T and B cell proliferation were studied in Sprague-Dawley male rats. Methods: Chemical sympathectomy was achieved with intraperitoneal injection of 6-hydroxydopamine 50 mg/kg/day for 3 successive days. Direct moxibustion (6-minute interval, 9 moxa ball, each of which weighing 0.007 g and burning for 40 seconds) was applied on unilateral anterior tibial muscle region where Zusanli (ST36) acupoint is located, once a day for 7 successive days. NK cell cytotoxicity was measured by $4hr-^{51}Cr$ release assay. Mitogen-induced lymphocyte proliferation was analyzed by [$^3H$]-thymidine incorporation assay. Results: NK cell cytotoxicity was suppressed by moxibustion, more in sympathectomized rats than in vehicle-treated rats. T cell proliferation induced by concanavalin A was not affected by moxibustion. B cell proliferation induced by lipopolysaccharide showed no significant change in vehicle-treated rats, but an increase in sympathectomized rats by moxibustion. Sympathectomy alone induced augmentation of NK cell cytotoxicity and suppression of T cell proliferation. Conclusion: These results suggest that SNS has no direct relation with moxibution-induced immunomodulation but has an important role in the mechanism to keep the homeostasis of immune system by tonically inhibiting excessive changes of various immune components.

Toxoplasmn gonnii, an intracellular protozoan infecting many kinds of eukaryotic cells, has been used to experimentally infect macrophages, epithelial cells, fibroblasts, and various cancer cells, but rarely T and B Iymphocytes or granulocytes. The present study was performed to determine the susceptibility of murine (BALB/c or CBA) splenic T and B llrnphocytes, and granulocytes to infection trio T. gondii RH tachyzoites. The ultrastructure of the infected host cells was observed by TEM, and the degree of intracellular parasite proliferation was quantified using 3H-uracil uptake assay. At 24 hrs post-culture, the host cell cytoplasm was found to contain 1 or 2, or a maximum of 7-8 tachyzoites. Infected T Iymphocytes demonstrated a peripherally displaced nucleus, a parasitophorous vacuole enveloping the parasite, and an increased number of mitochondria. In B Iymphocytes infected with tachyzoites, RER was not well developed compared to uninfected B Iymphocytes. Uninfected granulocytes contained many electron dense granules, but T. gondii-infected granulocytes demonstrated a decreased number of granules. Based on the 3H-uracil uptake assay. the susceptibility of T and B Iymphocytes, and granulocytes, to infection with T. gonnii tachyzoites was fairly high irrespective of cell type and strain of mouse. This strongly suggests deterioration in the functioning of infected host immune cells.

This experiment was performed on mice to investigate the effects of an immunopotentiator, picibanil(PC), on the immune responses such as phagocytic activity of reticuloen-dothelial(RE) system, E rosette formation rate of splenic lmphocytes and morphological changes of lymph node tissue. Groups of mice were treated with a single(1KE/kg BW) or sequential(0.1, 0.25 and 0.5KE/kg BW for successive 3 days) intravenous injections of PC. PC treated and untreated control mice were sensitized with 50% sheep erythrocyte suspension(0.2ml/mouse) at 1, 3, 5, 7 and 10 days after PC treatment. Functional and morphological examinations were carried out 5 days after sensitization. The following results were obtained: The phagocytic activity of RE system and the weight of liver and spleen were increased significantly at 3rd, 5th and 7th day. The peripheral polymorphonuclear leukocyte and percent of lymphocyte and monocyte were slightly increased. The rates of E rosette formation of splenic lymphotytes, sequential PC treated groups were more increased at 3rd and 5th day in sequential PC treated groups than in single treated groups. Thereafter it returned gradually to the control level by the time of 10th day. Microscopically primary lymph follicles with indistinct germinal center (GC) were partially disrupted and the parafollicular areas were consisted of the pyroninophilic cells in control group. In PC treated group, the parafollicular areas were markedly proliferated and developments of secondary lymph follicles with enlarged and prominent GC were more pronounced in the sequential injected groups compared to single injected groups. These results indicate that PC affected not only parafollicular area of the T-cell area, but also GC of the B-cell area. It suggests that PC may potentiate both cell mediated immunity and humoral immunity.

The purpose of this research was to investigate the effect of Sojagangqi-tang(SJGQT) on the immune cell activity. The addition of SJGQT enhanced the proliferation of cultured-mice splenocytes and thymocytes. Administration of SJGQT(250 mg/kg) accelerated the subpopulation of splenic T lymphocytes especially CD/sup 4+/-TH cells in BALB/c mice. But high concentration(500 mg/kg) of SJGQT decreased the splenic T, B lymphocytes and thymic Tc (CD/sup 8+/) lymphocytes. Oral administration of SJGQT(250 mg/kg) significantly enhanced the production of IFN-γ and IL-4 in mice serum. And also, the addition of SJGQT(100 ㎍/ml) inhibited the proliferation of cultured-Jurkat leukemia cells in vitro. These results suggest that SJGQT have a cellular immuno-modulatory effect and anti-cancer property action

The purpose of this research was to investigate the effects of the administration of Juglandis Semen without inner cortex (JE) or with inner cortex (JEIC) on activity of splenocytes and peritoneal macrophages in BALB/C mice. JE (300 mg/kg, p.o.) did not affect the cell viability of T- and B-lymphocytes in murine splenocytes, but JEIC (300mg/kg, p.o.) increased the cell viability of T- and B-lymphocytes. Furthermore, JE decreased the population of B220$^+$ cells in splenocytes, but JEIC enhanced the population of Thyl$^+$ cells. Also, JEIC enhanced the population of splenic CD4$^+$ cells. JE decreased the production of nitric oxide and the phagocytic activity of peritoneal macrophages, but JEIC increased the production of nitric oxide and the phagocytic activity of peritoneal macrophages. These results suggest that JEIC is more potent than JE against the immune response induced by splenocytes and macrophages.
