ABSTRACT
OBJECTIVE@#To evaluate the effect of "Shuganjieyu" (SGJY) capsules on neuronal apoptosis in hippocampal CA3 area and the expression of caspase-3 in the brain of rat depression model, and to investigate its pharmacological mechanisms in depression treatment.@*METHODS@#Adult male SD rats were randomly divided into 4 groups a control, a model, a SGJY and a fluoxetine group. The rat depression model was established under chronic unpredictable mild stress (CUMS) and separate feeding. The behaviors were measured by open-field test, sucrose consumption and forced swimming test. We observed the neuronal morphology structure and neuronal apoptosis in the hippocampal CA3 area. We detected the rat caspase-3 expression level of medial prefrontal cortex ( mPFC) and hippocampal CA3 area by Western blot.@*RESULTS@#After 21-day stress, compared with the model group, spontaneous activity and sucrose consumption and preference percentage of the rats in the SGJY group significantly increased, while the immobility time in forced swimming test, the number of apoptotic cells and the protein levels of caspase-3 significantly reduced (P0.05).@*CONCLUSION@#SGJY capsules can reduce the depression symptoms of CUMS and help to increase hippocampal neuron generation, survival and neogenesis, reduce the protein levels of caspase-3, and reverse neurocyte apoptosis in the rat depression model with the same efficacy as fluoxetine.
