Abstract

This study aimed to evaluate the anti-stress effects of Palmuljungjiwon and Gamipalmuljungjiwon on the contents of monoamines in the regional brain of mice immobilized stress. The experimental animals were immobilized in stress cylinder(height: 15cm, diameter: 3cm) for 15 minutes, and administered of Palmuljungjiwon(1.14mg/l0g) and Gamipalmuljungjiwon(1.17mg/10g) water 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. The following results were obtained : 1. In frontal cortex, the contents of norepinephrine a little decreased in all of the administered group, but the statistical significance was not recognized. The contents of dopamine were decreased with statistical significantly in Gamipalmuljungjiwon administered group compared to control group. The contents of serotonin were decreased with statistical significance in PalmulJungjiwon administered group compared to control group. 2. In hypothalamus, the contents of norepinephrine were decreased with statistical significantly in all of the administered group compared to control group. The contents of dopamine were decreased in all of the administered group compared to control group, but the statistical significance was not recognized. The contents of serotonin were decreased with statistical significantly in Gamipalmuljungjiwon administered group compared to control group. 3. In corpus striatum, the contents of norepinephrine were decreased with statistical significantly in Gamipalmuljungjiwon administered group compared to control group. The contents of dopamine were decreased in all of the administered group compared to control group, but the statistical significance was not recognized. The contents of serotonin were decreased with statistical significance in all of the administered group compared to control group 4. In hippocampus, the content of norepinephrine and dopamine a little decreased in all of the administered group, but the statistical significance was not recognized. The contents of serotonin were decreased with statistical significance in all of the administered group compared to control group. In conclusion, this study shows that Palmuljungjiwon and Gamipalmuljungjiwon are significantly effective on reducing and preventing stress in mice.
