  • The purpose of this Study was to investigate effect of TakliSodokSan(TSS) on the anti-tumor, immunocytes and nitric oxide(NO) production from mice peritoneal macrophages. This Study estimated the proliferation of L1210 cell lines, A431 cell lines, Hep-G2 cell lines, K562 cell lines, 3T3 cell lines, mouse thymocytes and mouse splenocytes and NO production from pcritoneal macrophages in vitro, and estimated the proliferation of L1210 cells, thymocytes and splenocytcs, NO production from peritoneal macrophages and body weight in L1210 cells-transplanted mice in vivo. The results were obtained as follows; 1. TSS inhibited significantly the proliferation of L1210, A431, Hep-G2, K562 cell lines in vitro. 2. TSS accelerated the proliferation of mice thymocytes and splenocytes in vitro. 3. TSS was not increased the nitric oxide production from mice peritoneal macrophages in vitro. 4. TSS inhibited significantly the proliferation of L1210 cells in Ll210 cells∼transplanted mice. 5. TSS accelerated the proliferation of mice thymocytes and splenocytes In L1210 cells-transplanted mice. 6. TSS was increased significantly the nitric oxide production from mice peritoneal macrophages in L1210 cells-transplanted mice. 7. TSS was increased the body weight as comparing with control group in Ll210 cells-transplanted mice.

  • The purpose of this research was to investigate the effects of Bopaewon-tang (BT) on immune reaction in mice. BT (500 mg/kg, p.o.) increased the viability of thymocytes, but decreased the viability of splenocytes in vivo. BT enhanced the population of $CD4^+$cells in thymocytes and enhanced the population of $Thy1^+$ cells in splenocytes and splenic $CD8^+$ cells. Also, BT decreased the production of IL-4 from splenocytes. Furthermore, BT enhanced the production of nitric oxide and the phagocytic activity of peritoneal macrophages. These results suggest that BT enhances the immune response via activation of thymocytes and macrophages.

  • For a long time Rhus verniciflua Stokes (RVS) has traditionally been used as a herbal plant. It is known to contain various biological activities. Previously, a crude ethanol extract from RVS was reported to have antioxidant effects, and antiproliferative activities, on human cancer cell lines. In this report, we prepared a highly purified ethanol extract from RVS, which did not contain the urushiol derivatives, named REEE-1 ($\underline{R}$hus $\underline{e}$thanol $\underline{e}$luted $\underline{e}$xtract-1), to investigate the mechanisms of the scavenging activity of hydroxyl radicals using mouse thymocytes. The results from the deoxyribose, DNA nicking, and glucose/glucose oxidase enzyme assays showed that REEE-1 contained a strong scavenging activity of oxygen free radicals, especially of hydroxyl radicals. However, interestingly, REEE-1 also showed cytotoxicity against the thymocytes, although the effect was variable, depending on the concentrations and times of treatment. The REEE-1-mediated cytotoxicity against thymocytes, which has been used as one of the well-characterized models for apoptosis studies, was verified to be apoptotic. This was proven by the following: the appearance of DNA laddering, increases in DNA fragmentation, low fluorescence intensity in the nuclei after propidium iodide staining, and positive Annexin V staining of the cells. These results suggested that REEE-1 had both antioxidative activity and cytotoxicity against the thymocytes, although the effect of the cytotoxicity was variable, depending on the dose and time of the treatment.

  • The purpose of this research was to investigate the effects of 50% ethylalcohol extracts of Lespedeza cuneata G. Don (LE) on the activity of murine immune cells. LE was administered orally once a day for 7 days at the dose of 250 mg/kg. LE increased the cell viability of thymocytes, splenocytes and peritoneal macrophages in vitro and in vivo system, but decreased the cell viability of thymocytes and splenocytes in the presence of concanavalin A in vivo system. Also, the administration of LE was increased the production of ${\gamma}$-interferone, but did not affect the production of interleukin-2 and interleukin-4. Furthermore, LE decreased the phagocytic activity of peritoneal macrophages in vitro and in vivo system, but enhanced the production of nitric oxide. These results suggest that LE has a immuno-regulative action via stimulation of immune cells proliferation.

  • The purpose of this research was to investigate effects of Astragali Radix(AR) and Armeniacae Semen(AS) on T-lymphocytes and peritoneal macrophages in mice. The proliferation of thymocytes and splenocytes were teated using macroplate-reader. The apoptosis and sub-population of T-lymphocytes were tested using a flow cytometer. Nitric oxide production was tested using a Griess reagents. The result were obtained as follow; 1. AR increased the proliferation of thymocytes and splenocytes. 2. AS decreased the proliferation of thymocytes and splenocytes. 3. AR and AS decreased No production fron peritoneal macrophages 4. AR and AS were accelerate T-lymphocytes apoptosis. 5. AR and AS increased $T_C$ cells population, but decreased $T_H$ cells population of T-lymphocyte.

  • On day 2 after treatment of Lewis rat with 25mg of hydrocortisone, the cell number in the thymus was reduced to less than 10% of the matched control. By day 12 after hydrocortisone treatment the thymic cell population was recovered almost its original value and on day 24 after treatment the number of thymocytes was equivalent to that of normal thymocytes. The density distribution profile of hydrocortisone treated rats as compared with normal rats showed a marked decrease in the denser fraction D while the lighter fractions. (A plus B, and C) showed a considerable proportional increase. The proportion of dead cells in thymus suspension from hydrocortisone treated rats was higher than that from their normal counterparts. On separation, the dead cells accumulated selectively in the pellet and A fraction. The response of the thymocytes from hydrocortisone treated rats to PHA was increased compared to that from normal rats. Among the subpopulations, D fraction, which was relatively unresponsive in normal rats, showed a marked increase in PHA response and C fraction showed some increase in the response.

  • Artemisia Folium is a preparation of dried leaves from Artemisia species and has been used traditionally to prevent or treat various kinds of woman's diseases. A similar preparation called Chinese Moxa has been used to treat rheumatism by moxibustion in Chinese medicine. A small carbohydrate fraction of approximately 1,000 dlaton from the water-soluble extract of the Artemisia Folium promoted survival of the mouse thymocytes in culture. A mouse gene array study suggested that the fraction might modulate Fas/FasL dependent apoptotic cell death and thus had influence on the survival of the thymocytes in culture. (omitted)

  • The purpose of this research was to investigate the effects of Seungyangikkitang (SIT) on the immune cells in BALB/c mice. SIT (500mg/kg) was administerd p.o. once a day for 7 days. SIT enhanced the proliferation of thymocytes, but decreased the proliferation of splenocytes. SIT enhanced the subpopulation of cytotoxic T cells in thymocytes and helper T cells in splenocytes, but did not affect the subpopulation of B220/Thy1 cells. SIT enhanced the production of γ-interferon and interleukin-2 in thymocytes, splenocytes and serum, but did not affect the production of interleukin-4. SIT suppressed the production of nitric oxide, but enhanced the lucigenin chemiluminescence and the engulfment of FITC-conjugated E. coli particles in peritoneal macrophages. These results suggest that SIT has a potent activity on the specific immunity via the cytokine secretion of Th1 cells and the non-specific immunity via the phagocytic activity of macrophages in vivo.
