Abstract

|
|
This study aimed to evaluate the anti-stress effects of soyosan and chyengansoyosan on the contents cold swimming stress.
The experimental animals were forced cold swimming stress for 3 minutes, and administered 4㎎/10g of soyosan and chyengansoyosan extract for 7 days before stress. The monoamines contents were measured by HPLC method in various part of mouse brain.
The following results were obtained :
1. In frontal cortex, the contenrs of norepinephrine ans dopamine increased significantly in the group administered chyrngansoyosan compared with in the group administered non chyengansoyosan and soyosan(control group) of mice stressed by cold swiming.
2. In hypothalamus, the content of norepinephrine increased with statistical significance in the group administered soyosan compared with control group of mice stressed by cold swimming.
3. The content of dopamine increased with statistical significance on the group administered chyenfansoyosan and compared with control group of mice stressed by cold swimming in hypothlaamus and hippocampus.
4. The content of serotonin increased with statistical significance in the group administered soyosan and compared with control group of mice stressed by cold swimming in hippocampus and corpus striatum.
5. In corpus striatum and hippocampus, the content of norepineohrine decreased with statistical significance in the group administered soyosan and chyengandoyosan compared with control group of mice stressed by cold swimming.
Judgding from the above results, this sthdy reaches a conclusion that soyosan or chyengansoyosas has significant effects in reducing stress.
