Abstract
Objectives : This study aimed to evaluate the anti-stress effects of Ansymondam-tang and Gamiondam-tang on the contents of monoamines in the regional brain of mice forced cold swimming stress in $4^{\circ}C$ water. Methods : The experimental animals were forced cold swimming stress for 3 minutes, and administered of Ansymondam-tang(2.2mg/10g) and Gamiondam-tang(0.83mg/10g) extract for 7 days before stress. The monoamines contents were measured by HPLC method in various part(frontal cortex, hypothalamus, corpus striatum and hippocampus) of mice brain. Results: 1. In frontal cortex, the contents of norepinephrine were increased with statistical significantly in all of the administered group compared to control group. The contents of dopamine and serotonin were increased in Gamiondam-tang administered group has a statistical significance. 2. In hypothalamus, the contents of dopamine were increased with statistical significance in all of the administered group compared to control group. 3. In corpus striatum the contents of norepinephrine were decreased and the contents of dopamine were increased with statistical significance in all of the administered group compared to control group. The contents of serotonin were increased in Gamiondam-tang administered group has a statistical significance. 4. In hippocampus the contents of norepinephrine were decreased with statistical significance in Gamiondam-tang administered group compared to control group. The contents of dopamine were increased in Ansymondam-tang administered group has a statistical significance. Conclusion : This study reaches a conclusion that Ansymondam-tang and Gamiondam-tang has significant effects .on reducing and preventing stress in mice. Especially Gamiondam-tang is more effective in the statistical significance than Ansymondam-tang on the monoamines change in the mice brain.
