Effects of Jiaotai Pill on inflammatory cytokines in depression model mice with chronic unpredictable mild stress / 中草药

ABSTRACT

Objective: To study the mechanism of Jiaotai Pill on inflammation and anti-inflammatory cytokines in mice with chronic unpredictable mild stress (CUMS) depression. Methods: Mice were treated with CUMS depression model, then the weight comparison, sugar test, opening experiment was conducted; The levels of IL-1β, IL-6 and TNF-α, IL-4, and IL-10 in the serum and hippocampus of rats were measured by enzyme-linked immunosorbent assay (ELISA), and rat hippocampal neuron morphology was observed by Nissl's staining. Results: Compared with the blank group, the consumption of sugar, the number of crosses and the number of vertical bars in the model group were significantly decreased; The levels of IL-1β, IL-6, TNF-α, and IL-4 in serum and hippocampus were significantly higher than those in the blank group, and IL-10 significantly reduced; Hippocampal neurons stratified unclear, arranged disorder, Nissie shallow staining or disappear. Compared with the model group, the consumption of sugar, the number of crosses and the number of vertical bars in Jiaotai Pill administration group were significantly increased; The levels of IL-1β, IL-6, and TNF-α in serum and hippocampus were significantly decreased, and the levels of IL-4 and IL-10 was significantly increased; Hippocampal neuronal stratification was more obvious, Nissl shallow staining. Conclusion: Jiaotai Pill can significantly improve the behavior of rat depression and hippocampal neuronal injury whose mechanism may be related to down-regulation of serum and hippocampus proinflammatory cytokines IL-1β, IL-6, TNF-α, up-regulation of anti-inflammatory cytokines IL-4 and IL-10.
