  • ln order to develope anti-inflammatory glucocorticoids for local use without systemic side-effects, ester and amide derivatives of 20$\xi$-dihydroprednisolonic acid have been prepared. When binding affinities of these compounds to glucocorticoid receptor of rat liver cytosol were compared, all a-isomer at C-20 showed higher binding affinities than the corres¬ponding $\beta$-isomer. The size of the substituents at C-21 had significant influences on binding affinities, which were related with their lipophilicity.

  • It has been known that quercetin is one of bioflavonid compounds and has anti-tumor effect by suppressing tumor growth in vitro and in vivo, including multiple biological effects by antioxidant and effective anti-inflammatory agent. The present study investigated whether quercetin can enhance antioxidant enzyme activity (glutathione proxidase: GPX, superoxide dismutase: SOD, catalase: CAT) and regulate the intracellular reactive oxygen intermediate levels on the B16F10 murine melanoma cells in the presensece of vitamin E, L-ascorbic acid (vitamin C) and reduced glutathione (GSH).

  • To develop a health-aid preparation of Dioscorea batatas (DB), lactic acid fermentation was attempted using a mixed starter comprising of Lactobacillus acidophilus, Lactobacillus plantarum, Bifidobacterium longum. The anaerobic fermentation of a 10% DB flour suspension gave a uniform suspension of pH 3.65, containing $8{\times}10^6$ CFU/mL lactic acid bacteria. During the administration of the lactic acid fermented DB (FDB) and DB to trinitrobenzene sulfonic acid (TNBS)-induced colitis mouse model, histological lesions, morphological damage, and myeloperoxidase acitivity were significantly reduced at a dosage of 200 and 400 mg/kg/day. Dose-response (200 and 400 mg/kg/day) studies revealed that FDB pre-treatment of mice significantly ameliorated the appearance of diarrhoea and the disruption of colonic architecture. In FDB-pretreated mice, there was a significant reduction in the degree of both neutrophil infiltration (measured as decrease in myeloperoxidase activity) and weight loss rates. Theses findings suggest that FDB exerts beneficial effects in experimental colitis and may be useful in the treatment of inflammatory bowel disease.

  • Objectives : This study aims at examining the effect of the fermentative extract of root of Sophorae Radix on the immuno-modulating activity. Methods : Cell viabilities were measured by MTT assay. Effect of SFS on nitric oxide(NO), hydrogen peroxide production from RAW 264.7 cells was accessed by Griess reagent assay. Effect of SFS on productions of inflammatory cytokines such as TNF-${\alpha}$, IL-6 in LPS-induced RAW 264.7 cells was accessed by a multiplex bead array assay based on xMAP technology. Results : The results of the experiment are as follows. 1. As a result of carrying out MTT assay to check the cellular toxicity of the fermentative extract of Sophorae Radix. There was not any excessive toxicity to the macrophage when the fermentative extract of root of Sophorae Radix was treated in different concentrations. 2. The fermentative extract of Sophorae Radix increased the generation of hydrogen peroxide in the macrophage and significantly restored the suppression of the generation of the hydrogen peroxide in the macrophage induced by LPS. 3. The fermentative extract of Sophorae Radix reduced the generation of NO in the macrophage and significantly suppressed the increase of the generation of NO in the macrophage induced by LPS. 4. The fermentative extract of Sophorae Radix significantly decreased the amount of TNF-${\alpha}$ generated in the macrophage induced by LPS when it was $25{\mu}g/mL$ or higher. Conclusion : These results suggest that SFS has anti-inflammatory moiety related with its inhibition of NO, hydrogen peroxide, TNF-${\alpha}$, IL-6, in macrophage led by LPS.
