1. Objectives: The purpose of this study is to investigate the effect of Suhwagije-tang(SGT) distillate on the immune activity of spleen cells of aged SD rats. 2. Methods: We used 10, 50, 72 weeks old SD rats in this study. Spleen cells from SD rats were stimulated with ConA and treated with 1% Vitamin C(Vit.C) or Suhwagijetang distillate(SGT). After 24 hours, the concentrations of IL-2, IL-4, IL-10, IFN-${\gamma}$ in the cell culture supernatant were measured by ELISA. 3. Results and Conclusions 1) At all concentration of SGT distillate, survival rates of liver cells were higher than the control group. In addition, 50% SGT distillate group's cell survival rates were significantly higher than other groups. 2) In 10 weeks SD rats(SGT group), the concentration of IL-2 significantly decreased in comparison with ConA group, Vit.C group. In 52 weeks SD rats(SGT group), the concentration of IL-2 significantly decreased in comparison with ConA group. 3) In 10, 52 weeks SD rats(SGT group), the concentration of IL-4 significantly decreased in comparison with ConA group. 4) In 10 weeks SD rats(SGT group), the concentration of IL-10 significantly decreased in comparison with ConA group. And in 72 weeks SD rats(SGT group), the concentration of IL-10 significantly increased in comparison with Vit.C group. 5) In 52, 72 weeks SD rats(SGT group), the concentration of IFN-${\gamma}$ significantly decreased in comparison with 10 weeks SD rats(SGT group). These results suggest that Suhwagije-tang(SGT) distillate has the effect of increasing the immune activity of spleen cells of aged SD rats.

The purpose of this research is to examine the effects of Kamijihwang-tang(KJHT) on CD+4 T cells and CD8+ T cell ovalbumin (OVA)-induced asthmatic mice. C57BL/6 mice were injected, inhaled and sprayed with OVA for 12 weeks (four a week) for asthma induction. Two experimental groups were treated with different concentrations of KJHT (400 mg/kg and 200 mg/kg) extract and cyclosporine A (10 mg/kg) for the later 8 weeks. At the end of the experiment, the mice lung, peripheral lymph node (PLN), and spleen were removed and CD4+ T cells and CD8 + T cells for analyzed by flow cytometer. Number of CD4+ T cells in lung, PLN, spleen of the KJHT group (400 mg/kg) were significantly decreased compared with that of control group. Number of CD8+ T cells in lung, PLN, spleen of the KJHT group (200 mg/kg) were significantly decreased compared with that of control group. The results of this study suggest that KJHT alleviated asthmatic hyperactivity through CD4+ and CD8+ T cells. Further study of relative cytokines is expected.

Folate, a precursor of the coenzyme tetrahydrofolate, plays an important role in DNA replication and cell proliferation, and thus could influence rapidly proliferating immune cells such as leukocytes and splenocytes. The effects of dietary folate on folate concentrations of plasma, thymus, spleen and leukocytes were investigated in rats. The animals were raised for 6 weeks on semipurifed experimental diets containing 0mg, 2mg, 4mg, 8mg folate/kg diet. Folate concentrations were determined microbiologically using Lactobacillus casei(ATCC 7469), and DNA strand breaks produced by alkaline treatment were analyzed fluorometrically. When compared to folate adequate diet, the folate deficient diet(0mg folate/kg diet) resulted in lowest folate levels in plasma, thymus, spleen and leukocytes, and the highest DNA strand breaks in spleen cells and leukocytes. Dietary folate levels significantly increased folate concentrations of immune tissues, leukocytes, and the plasma in a dose dependent manner, folate concentrations being highest with a diet providing 8mg folate/kg diet. The percentages of the double strand DNA remaining in the splenocytes and leukocytes after alkaline treatment were significantly increased with higher amounts of dietary folate in a dose dependent manner. Folate intakes of 8mg than 4mg/kg diet was found to be more effective in the prevention of DNA strand breaks. The results of this study suggest that increased folate above the requirement level could improve DNA stabilities in immune cells.

Bifidobacteria has been suggested to exert health promoting effects on the host by maintaining microbial flora and modulating immune functions in the human intestine. We assessed modulatory effects of the different cell fractions of Bifidobacterium sp. BGN4 on macrophage cells and other immune cells from the spleen and Peyer's patches (PP) of mouse. Cell free extracts (CFE) of the BGN4 fractions induced well-developed morphological changes in the macrophages and increased the phagocytic activity more effectively than other fractions in the mouse peritoneal cells. Nitric oxide (NO) production was significantly reduced by both the cell walls (CW) and CFE in the cultured cells from the spleen and PP. The production of interleukin-6 (IL-6) and interleukin-10 (IL-10) was eminent in the spleen cells treated with experimental BGN4 cell fractions. However, in the PP cells, IL-6 was slightly decreased by the treatment with the whole cell (WC) and CW, whereas IL-10 was significantly increased by the treatment with the CW and CFE. These results suggest that different types of bifidobacterial cell fractions may have differential immunomodulatory activities depending on their location within the host immune system.

A polysaccharide fraction, AIP1, purified from Artemisia iwayomogi was shown to have immunomodulating and anti-tumor activities in mice. In order to determine how the AIP1 fraction exhibits the immunomodulating activity, the effect of the fraction on the apoptosis of mouse spleen cells was investigated. Treatment of the mouse spleen cells with the AIP1 fraction resulted ,in the suppression of apoptotic death and an extension of cell survival in culture, indicating that the fraction might modulate the death of spleen cells. Treatment of the mice with the AIP1 fraction in vivo also resulted in less apoptosis of the spleen cells, which indicates the physiological relevance of the anti-apoptosis effect of the fraction in vitro. A mouse gene array was used to determine the profile of the gene expression change showing a pattern of up- and down-regulated genes by the AIP1 treatment. This study provides preliminary information regarding the immunomodulatory mechanism of the AIP1 fraction.

Rg3 is a derivative of triterpenoid dammarane, which originally extracted from Red Ginseng, which have been known to have neuroprotective, vasodilator, antioxidative, antimetastasis, and direct anticancer effects. These various backgrounds of Rg3 can provide an additional interest in respect to the “hematopoiesis” in bone marrow and spleen cells. We, therefore, have investigated what effects and correlates of Rg3 (e.g. suppression and side effects) are affected in relation with the bone marrow and spleen cells of mouse. (omitted)

These experiments were conducted to investigate the effects of Cervi cornu extract on lymphocyte blastogenesis in spleen, thymus, lymph node, born marrow cells of Balb/c mouse, haemagglutination reaction against sheep red blood cell (SRBC), plaque forming cell (PFC) assay against SRBC and IL-2 production. Lymphocyte blastogenesis was determined by $[^3H]-thymidine$ incorporation. According to the lymphcoyte blastogenesis test on the immune cell. Ceriv cornu extrat was showed a potent mitogenic activity on the spleen and lymph node cells, but had mild mitogenic activity on the thymus and born marrow cells. Mitogenic active component of Crevi cornu extract was identified to be materials where molecular weights are higher than 5,000 by membrane filteration method. Cervi cornu extrat was shown to increase mitogenic effect on the lipopolysaccharide (LPS)-stimulated spleen cells significantly, but decrease mitogenic effect on the Con A stimulated spleen cell at the concentration 0.3%, 1% and 3%. Ceriv cornu extract didn't show to be haemagglutination reaction and showed to inhibit the Con A-induced haemagglutination reaction against SREC. Result of SRBC-PEC test. Ceriv cornu extract significantly increase the number of PEC at the concentration of 0.1% and 1%. When IL-2 or IL-4 production was determined by proliferation of CTLL-2 cells. Ceriv cornu extract was not shown to stimulate the production of IL-2. From the above results, it is shown that Ceriv cornu extract increased antibody production by B cells, but nor IL-2 production by helper T cells.
