The Antistress Effects of Semen Ziziphi Spinosae Extract

The effects of Semen Ziziphi Spinosae extract were tested for the anti-stress action. 100g of crude drug of Semen Ziziphi Spinosae was extracted with pure water and the total extractive was evaporated under reduced pressure to give 10.7g. ICR male mice($20{\pm}2g$) were fed orally with the dose of 100mg/kg/day for five days. Foot shock was given to make experimental environment of physiological stress. Foot shock mice were placed individually in the foot shock compartments and sociopsychological mice were placed nonfoot shock compartment-the side of foot shock compartments. Mice were exposed to sociopsychological stress by restraining and seeing foot shock stressed mice for one hour for five days. Semen Ziziphi Spinosae extract administered group showed a significant decrease of serum corticosterone secretion compared with control group. Noradrenaline secretions in the dorsal cortex of brain were increased but not significant. Lipid peroxidation of the liver of mice were tested by measuring malondialdehyde, and Semen Ziziphi Spinosae extract had tendency of decreasing lipid peroxidation but not significant. But Semen Ziziphi Spinosae extract administration had the effect of decreasing serum level of aspartate aminotransferase and malondialdehyde. These results suggest that Semen Ziziphi Spinosae extract can effectively rid the sociopsychological stress and stress concerned diseases.
