Objectives : In the present study, the effect of Kuwonsimsin-hwan (KSS) was tested in methotrexate (MTX)-induced immunosuppressed SD rats. Methods : Methotrexate was fed to white rats once a day for 4 days. After the immune responses of the rats deteriorated, dried extracts of Kuwonsimsin-hwan mixed in water was fed to the rats once a day for 14 days. We then measured the number of lymphocytes in peripheral blood and the percentage of B-cells, T-cells, CD3+CD4+T-cells, CD3+CD8+ T-cells and IL-2 productivity sampled from spleen and peripheral region. Results : (1) The number of lymphocytes and the percentage of T-cells and CD3+CD4+ T-cellsin peripheral blood increased significantly in the KSS group as compared with the control group. (2) The percentage of B-cells, CD3+CD8+ T-cells, and CD4+/CD8+ T-cells in peripheral blood were not different statistically. (3) The percentage of T-cells in spleen and IL-2 productivity of spleen cells increased significantly in the KSS group as compared with the control group. (4) The percentage of CD3+CD4+ T-cells in spleen increased in KSS the group as compared with the control group but without statistical significance. (5) The percentage of B-cells, CD3+CD8+ T-cells, and CD4+/CD8+ T-cells in spleen were not different statistically. Conclusion : It is concluded that Kuwonsimsin-hwan has immunostimulating effect on MTX-induced immunosuppressed SD rats.

A total number of 31 types of seaweed were assessed with regard to their effects on the proliferation of mouse spleen and thymus cells in a culture, using an MTT reduction assay. Acetone:dichloromethane (1:1) extracts of three seaweed plants: Derbesia marina, Sargassum sp., and Hisikia fuziformis, exhibited significantly positive effects on the survival of mouse spleen and thymus cells in vitro. The acetone:dichloromethane (1:1) extracts of Sargassum sp., in particular, much more potent effects on thymus cell activation than did any of the other types of seaweed. However, the methanol extracts of Sargassum ringgoldianium and Chondrus crispus exerted a stimulatory influence only on the proliferation of mouse spleen cells, whereas the methanol extracts of Grateloupia lanceolata exhibited significant cell proliferation properties in both spleen and thymus cells.

As a part of our ongoing effort to develop new antineoplastic immunostimulator from natural sources, bioassay-directed fractionationn of polysaccharides from Korean red ginseng was carried out by observing the proliferation of marine spleen cells and the generation of lymphoklne activated killer (LAK) cells. The acidic polysaccharide fractions proliferated spleen cells and generated LAK cells in proportion to their acidity in vitro. The LAK cell which was induced by ginseng showed tumoricidal activity against both NK celt sensitive and insensitive tumor target cells without major histocompatibility (MHC) restriction. Adherent macrophages and CD4+helper T cells were involved in the generation of the LAK cells. The acidic polysaccharide from Korean red ginseng synerglzed with recombinant IL-2 (rIff-2) at lower than 3 U/ml. The optimal doses of the acidic polysaccharide from Korean red ginseng for the proliferation of spleen cells and for the generation of LAK cells were 1 mg/ml and 100 $\mu\textrm{g}$/ml, respectively; this means that the mechanisms for the both activities may be different from each other.

Objective: The purpose of this study was to evaluate the effect of Samjawhadam-jeon (SJHDJ; 三子化痰煎) on immune cells in OVA-induced asthmatic mice. Material and Methods : C57BL/6 mice were injected, inhaled and sprayed with OVA for 12 weeks (four times a week) for asthma induction. Two experimental groups were treated with different concentrations of SJHDJ group (400 mg/kg) extracts and cyclosporin A (10 mg/kg) for the latter 8 weeks. At the end of the experiment, the mouse lung. peripheral lymph node (PLN) and spleen were removed and immune cells were analyzed by flow cytometer. Results : Lung weight, total cells in lung, PLN, and spleen of the SJHDJ group decreased significantly compared with that of the control group. Number of $CD3e^+/CD69^+$, $CD3e^+/DX5^+$ cells in lung, PLN and spleen, number of $CD3^+$ cells in PLN and spleen, number of $CD3e^-/CCR3^+$ cells in lung and PLN, and number of $B220^+/IgE^+$ cells in PLN of the SJHDJ group decreased compared with that of the control group. Number of $CD4^+/CD25^+$ cells in PLN and spleen of the SJHDJ group increased compared with that of the control group. Conclusion : These results demonstrate that SJHDJ will be a desirable alternative therapy for allergic asthma by inhibiting the expression of immune cells.

Infection with virulent or attenuated Salmonella typhimuriumhas known to induce reduction in proliferative responses of spleen cells. We investigated a role of lipid A from S. typhimurium, a B cell mitogen, on proliferation of spleen cells by T cell mitogens such as concanavaline A and phytohemagglutinin under in vitro and ex vivo conditions. Lipid A alone induced proliferation of spleen cells in vitroin a dose-dependent manner. However, subsequent treatment of concanavaline A or phytohemagglutin in after lipid A treatment induced proliferation suppression of murine spleen cells in vitro and ex vivo. Removal of macrophages from spleen cells, which were obtained from a lipid A-injected mouse, restored proliferation by concanavaline A and phytohemagglutinin, indicating that macrophages appeared to play a role in lipid A-induced suppression. Secreted molecules from macrophages did not accounted for the suppression because suppressive effect was not achieved when the supernatant from macrophage-containing spleen cell culture was conditoned to macrophage-depleted spleen cell culture. Co-culture of spleen cells from lipid A-treated and - untreated mice showed proliferation suppression as increasing cell numbers of lipid A-treated mouse. These data suggested that the cell-to-cell contact of macrophage with splenic lymphocyte cells is responsible for immune responses against lipid A, which is applicable to the case of human S. typhi infection.

To determine the effect of immunopotentiating activity of cellular components of Lactococcus lactis ssp. lactis, the immune function was analyzed in vitro using mice cells. When stimulated with mitogens, productions of $IFN-{\gamma}$, IL-12, $TNF-{\alpha}$, and IL-6 were enhanced in spleen cells treated with cellular components, with IL-4 production being the highest in spleen cells treated with cytoplasm fraction. Without mitogen stimulation, the productions of $IFN-{\gamma}$ and IL-12 were the highest in spleen cells treated with heat-killed whole cell. $TNF-{\alpha}$ and IL-6 productions were also high in spleen cells treated with all cellular components. Only heat-killed whole cell showed significant enhancement in natural killer cell activity. In peritoneal exudates cells, $TNF-{\alpha}$ production was enhanced significantly by all cellular components of Lactococcus lactis ssp. lactis These results indicate that the cellular components of Lactococcus lactis ssp. lactis are capable of stimulating immune cells to produce cytokines, and that both their cell walls and cytoplasm fraction contribute to these capacities.

The most serious problem resulting from estrogen deficiency induce osteo porosis. Recently, they make efforts to inquire a relation between hematopoietic organ and bone loss due to estrogen deficiency. Estrogen have an effect on growth and formation of skeletal system, and inhibit bone resorption under the influence of osteoblast and osteoclast, and basically inhibit the increase of hematopoietic progenitor and immune factor connected with bone resorption and prevent the osteoid formation. The purpose of this article was to observe the change of spleen and effect on hematopoietic function following estrogen administration. In this study, female rats of 150g weight was ovariectomized, after 70 days, experimental group was injected estrogen at interval of a week and sacrificed on 1, 2, 3, 4, 6 weeks. Control group was sacrificed after ovariectomy on 11, 12, 13, 14, 16 weeks without estrogen injection, and normal rats were sacrificed for harvest of spleen and femur. Paraffin sections and H&E stain was performed, and observed under light microscope. The obtained results were as follows. 1. From 11 to 12 weeks at bone marrow of control group, hematopoietic cells were decreased in comparison with normal group, and lipid infiltration was seen, and irregular bone remodelling was seen after 13 weeks. From 14 to 16 weeks, there were more decreased hematopoietic cells and lipid degeneration, and lipid degeneration of hematopoietic cells appeared. 2. All the bone marrow of experimental group, the structure of hematopoietic cells with decreased lipid infiltration was recovered from 2 weeks of estrogen adminstration and maintained to 6 weeks. 3. At spleen of control group, borders of white and red pulp was not well demarcated, and size of white pulp was decreased. 4. At spleen of experimental group, borders between white and red pulp have been well demarcated from 3 weeks of estrogen adminstration relatively, and white pulp was increased with distinct border. From above findings, we could regarded that estrogen deficiency due to ovariectomy influenced on hematopoietic cells of bone marrow and spleen, and histologic recovery of hematopoietic cells were observed after 3 weeks of estrogen adminstration even if it was not reach to normal group.

Gaucher's disease is an autosomal recessive disorder resulting from mutation at the glucocerebrosidase locus on chromosome 1q21. As a result, glucocerebroside accumulates principally in the phagocytic cells known as Gaucher cells. In our case, a five-year old girl was admitted with seven days' history of fever and abdominal distension. At physical examination the patient had hepatosplenomegaly. Laboratory tests revealed a hemoglobin concentration of 2.8g/L: platelet counts of $23,000/{\mu}l$: normal range of white cell and differential counts, and negative Coombs' test. Liver enzymes were normal. For the evaluation of hepatosplenomegaly, fine needle aspiration was performed blindly against the palpable spleen. Wet-fixed hematoxylin and eosin-stained smears are made. The smears from the spleen showed predominantly macrophages with abundant cytoplasm and rather small, uniform, often eccentric nuclei with small nucleoli. The multinucleated cells were often found. The cytoplasm was pale, with more or less distinct fibrillarity. The cells had the characteristic appearance of Gaucher cells. Gaucher cells were also found in the tissue section from the liver, spleen and lymph node and the bone marrow aspirate. The diagnosis was later confirmed by determination of bela-glucosidase activity in peripheral blood leucocytes. Fine needle aspiration of the spleen is considered as a convenient procedure with a low complication rate for the diagnosis of lysosomal storage disease.
