In an attempt to investigate the effect of Beekeumsan on the hemostatic action and isolated uterine muscle, Beekeumsan was administered orally and the bleeding time in mouse tail, prothrombin time in vitro were estimated. Its activity on the isolated uterine muscle in rats were investigated. The following results were obtained; The bleeding time was not shortened, but the plasma prothrombin time in vitro was significantly shortened. The uterotonic action produced by the Beekeumsan was not inhibited by pretreatment of atropine, but was slightly inhibited by cyprohep tadine and completely inhibited by pretreatment of diltiazem.

Experimental studies were conducted to investigate the hemostatic effect of the water extracts of Kwibitang. For this purpose, the effects of the extracts on the bleeding time in mouse tail and prothrombin time in vitro were estimated. Furthermore, its activity on the isolated uterine muscle in rats were investigated. The results obtained were as following; The bleeding time was not shortened, but the plasma prothrombin time in vitro test was significantly shortened. The uterotonic action produced by the extract was not inhibited by pretreatment of atropine and cyproheptadine, but completely inhibited by pretreatment of diltiazem at the doses of 10<sup>-5</sup>g/㎖.

Objectives: This study was conducted to assess the effects of Hwanggimacmundong-tang extract (HM) on obese rats with estrogen deficiency. Methods: The experiments were performed with ovariectomized rats as estrogen-deficient obesity model. Rats were grouped NC (Normal Control Group; sham operation group), OC (Obesity Control Group; estrogen-deficient group), HML (20 mg/kg/day), HMH (100 mg/kg/day). HM was administered orally for six weeks. Body weights and serum lipid level were measured, and real-time PCR was performed to estimate the effect of HM on gene expression in liver. Results: HM decreased the total cholesterol and triglyceride in serum. And HM increased leptin, CPT1 gene expression in liver tissue of obese rats with estrogen deficiency. However HM decreased $PPAR{\gamma}$, $PGC-1{\alpha}$, HMGCR, CYP8B1, LPL, ACAT1, ACAT2, ApoB, ACOX gene expression in liver tissue of obese rats with estrogen deficiency. Conclusions: It is concluded that HM reduced total cholesterol and triglyceride in serum, and regulate gene expression related to lipid metabolism. These results indicate Hwanggimacmundong-tang that might have potential for treatment of obesity and complications during the menopause caused by estrogen-deficiency.

The KGBT has been used to weak children with anorexia, fatigue, and growth retardation. This study was carried out to prove the effects of the hematopoiesis and the immune proliferation by KGBT. Previously, C57BL/6 mice was treated with cyclophosphamide(100mg/kg) for leukopenia, and then administered KGBT (concentration is 1.37 g/kg, 504 mg/kg, and 137 mg/kg) to the treated mice. The mice was analyzed expression of thrombopoietin(TPO), stem cell factor(SCF) and interleukin-3 from bone marrow cell, interleukin-10 (IL-10), and interferon-$ {\gamma}$(INF-${\gamma}$) from splenic cell, and NOSⅡ gene from macrophage using by RT-PCR. Also proliferation of immune cell was analyzed using 3H-thymidine uptake and flow cytometery in splenic cells. The results were obtained as follows ; 1. The total number of WBC, RBC and PLT was increased in the KGBT treated group than in the control group. 2. In vitro, the proliferation of splenic cells was increased in normal, control, and KGBT treated group. And Administration of KGBT was reduced the cytotoxicity by CTX. 3. In bone marrow cell, the gene expression of immune regulatory factor that associated with hematopoiesis, such as TPO, SCF, and IL-13 was increased in the KGBT treated group than control. 4 The titer of hemagglutinin and hemolysin was increased in the KGBT treated group than control. 5. In analysis of positive leucocytes from splenic cell of BALB/c mice, the subpopulation percent of CD4+, CD8+,and CD19+ was increased in the KGBT treated group than control.

The expression of IL-10 gene was reduced in the KGBT treated group than control, whereas the expression of INF-${\gamma}$ was increased in the KGBT treated group. 7. In macrophage, the production of NO and gene expression of NOSH was increased in the KGBT treated group than control. 8. After infection of EMC virus, the survival time of infected mice was longer in the KGBT treated group than control.

Objectives: This study was conducted to evaluate the effects of Hyeolbuchugeo-tang (HBC) on Osteoporosis. Methods: We induced RAW 264.7 cells to differentiate to Osteoclasts by RANKL and treated RANKL-induced RAW 264.7 cells with HBC (0, 150, 350, $700{\mu}g/ml$). To measure osteoclast differentiation and activation, we counted TRAP (+) MNCs and measured mRNA expressions of its related genes (TRAP, MMP-9, cathepsin K, NFATc1, c-Fos, MITF, iNOS, COX-2, TNF-${\alpha}$) by RT-PCR. To assess bone resorption, the Bone pit formation were examined under a microscope. Results: HBC decreased TRAP (+) MNCs and inhibited mRNA expressions of TRAP, MMP-9, cathepsin K, NFATc1, c-Fos, MITF in osteoclast. And HBC inhibited Bone pit formation. Conclusions: HBC inhibited osteoclast differentiation and activation and bone resorption. Taken together, these results indicate that HBC might have potentials for prevention and treatment of Osteoporosis.
