Objectives : The effects of Pinelliae Rhizoma extract(PRe) were tested for the anti-stress action. Methods : PRe was fed to ICR male mice($20{pm}2g$) orally with the dose of 100 mg/kg/day for five days. Mice were exposed to sociopsychological stress by restraining and seeing foot shock stressed mice for one hour for five days. Results : PRe administration had the effect of decreasing serum level of lipid peroxidation. The elevated plus-maze test is designed to detect the effect of anxiolytic drugs, and PRe administration group showed a significant increase of latency time. From Microarray, common features between mind-stimulus related genes and body-stimulus related genes were not so abundant When PRe was administered, there were some changes in distributions of mind-stimulus related genes but the distributions were not recovered to normal status. Conclusions : These results suggest that PRe can effectively rid the sociopsychological stress and stress concrened diseases.
