This study was designed to investigate the Effects of Smilacis Glabrae Rhizoma(SGR) on the gout. After pretreatment of SGR(50, 500mg/kg) for 5days, the Effects of SGR was evaluated on changes Joint value increase ratio, Serum albumin, Serum globulin, glutamate dxalacetate transminase(AST), glutanate pyruvate transminase(ALT), blood urea nitrogen(BUN), Serum creatitine, Serum uric acid, xanthine oxidase activity, WBC, Erythrocyte Sedimentation Rate(ESR), platelet. The results were obtained as follows ; Joint valueincrease ratio was decreased in 50mg/kg, 500mg/kg SGR taken group, but changes were not significantly different with the control group. AST, ALT were not significantly different in all SGR taken groups compared with the control group. Serum BUN, creatinine were significantly decreased in 500mg/kg SGR taken group compared with control group. ESR was significantly decreased in all SGR taken groups compared with the control group. WBC, platelet were significantly decreased in 500mg/kg SGR taken group compared with control group. Serum uric acid was not significantly different in all SGR taken groups compared with the control group. Xanthine oxidase activity was significantly decreased in 500mg/kg SGR taken group compared with control group. From above results, it may be concluded that SGR can be used for treatment and prevention of gout.
