Objective: To investigate the antidepressant effect of Xiaoyao Shuxin capsule (XYSX) and its possible mechanism. Method: Sixty ICR mice were randomly divided into six groups:normal control group
model group
Xiaoyao Wan (1.5 g· kg-1) group and XYSX(0.5
1.5
4.5 g· kg-1) group. Except the normal control group
the other groups were treated with the chronic unpredictable mild stress stimulation (CUMS) combined with lonely raising for 35 d. Then the forced swimming test and free-activity test were carried out. The activity of superoxide dismutase(SOD) and the content of malondialdehyde(MDA) in blood serum were measured by the UV-spectrophotometric determination method and the content of serotonin(5-HT)
adrenocorticotropic hormone(ACTH) and brain-derived neurotrophic factor(BDNF) in brain were determined by ELISA. Result: XYSX (1.5
4.5 g· kg-1) could reduce the time of immovability of the depressed mice
increase the activity of SOD
reduce the content of MDA in depressed mice
increase the content of 5-HT and BDNF and decrease the content of ACTH in the brain of the depressed mice. XYSX (0.5
1.5
4.5 g· kg-1) could increase the time of free-activity. Conclusion: XYSX has a prominent therapeutic effect on mice model of chronic stress-induced depression and the mechanism might be related with the reduction of the content of monoamine neurotransmitters
the hyperfunction of hypothalamus-pituitary-adrenal(HPA)
the improvement of the neural plasticity and free radical damage.
