鸡豆黄素A对围绝经期抑郁症大鼠的神经保护作用及机制研究
Research on effects and mechanism of Bioch A neuroprotection to rats in perimenopausal depression disorder
摘要
Abstract
Objective To explore behavioral influence and neuroprotective mechanism of Bioch A in inperimenopausal depression disorder (PDD) rats model. Methods Rats model of PDD was established via two-step methods ovariectomy (OVX) and chronic unpre-dictable mild stress (CUMS).Rats'behavioral changes were observed through open-field tests and forced-swimming tests;a HPLC method with electrochemical detector is applied for determination of dopamine (DA), arterenol (NA) and 5-hydroxytryptamine (5-HT) content in rats;Western blot was used to detecting expression of interleukin-1β (IL-1β), interleukin-1 converting enzyme (Caspase-1), protein kinase A (PKA), phosphorylation protein kinase A (p-PKA), cAMP response element binding pro-tein (CREB), phosphorylation cAMP response element binding pro-tein (p-CREB), brain-derived neurotrophic factor (BDNF), and tyrosine protein kinase B (TrkB).Results After Bioch A and fluoxetine treatment, rats in PDD scored obviously higher at both horizontal motion and vertical motion;immobility time in forced swimming was significantly shortened (P<0.05, P<0.01);expression level of IL-1βand Caspase-1 lowered in different degrees (P<0.05, P<0.01);5-HT content was clearly increased;phosphorylation level of PKA and CREB, expression level of BD-NF, Trk B and mRNA all rose in different degrees (P<0.05, P<0.01), in comparison with those of model group. Conclusion Bioch A has a certain antagonistic effect on PDD, and its mechanism is mainly related to increasing hippocampal 5-HT content and up-regulating hippocampal cAMP-CREB-BDNF signaling pathway protein expression.关键词
