Methods Twenty-four male Wistar rats were randomly divided into blank,model, Trazodone, and Kaixin Powder groups, six rats in each group. In addition to the blank control group, other groups were established the depression model induced by CUMS combined with isolated feeding. At the same time, Trazodone group and Kaixin Powder group were treated with corresponding drugs for 3 weeks. After 3 weeks of administration, the rats were sacrificed, and a series of indexes were measured such as the contents of 5-HT, m RNA expression levels of 5-HT1 A and 5-HT2 A receptors, protein expression levels of 5-HT1 A and 5-HT2 A receptors, and so on. Results A series of indexes in the model group were decreased significantly such as the body weight growth, the sugar water intake, the score of Open Field Test, the content of5-HT in the hippocampus, expression of m RNA, and protein in 5-HT1 A receptor, while the expression of m RNA and protein in 5-HT2 A receptor were increased significantly.Compared with the model group, the indexes were ameliorated in Trazodone and Kaixin Powder groups. Kaixin Powder is better than Trazodone in decreasing the level of protein in 5-HT2 A receptor. Conclusion The result indicated that the depression performance of depressed rats induced by CUMS can be ameliorated by Kaixin Powder,and the mechanism maybe concerned with increasing the contents of 5-HT, exciting 5-HT1 A receptor, and antagonising 5- HT2 A receptor.展开更多
