Abstract:
Objective To investigate the effects of Zuogui Jiangtang Jieyu Formulation(ZGJTJYF)on the expression of excitatory amino acid transporter 3 (EAAT 3 )and vesicular glutamate transporter 2 (VGLUT2)inhippocampalastrocytesofdiabetesmellitusratswithdepression(DD).Methods DD rats were induced by intragastrical administration of high-fat diet,tail intravenous injection of streptozoto-cin (STZ)with 28 days’chronic stress and were randomly divided into five groups—model group,posi-tive drug group (metformin with fluoxetine),high-,middle-,and low- dose of ZGJTJYF (high-dose, mid-dose,and low-dose)group.Healthy SD rats were assigned into blank control group.After four con-secutive weeks the cognition ability was measured using Morris water maze,and the expression of EAAT3 and VGLUT2 weredetected by using immunohistochemical double labeling method.Results Compared with blank control group,escape latency of model group was significantly longer (P<0.01 ),EAAT 3 expression decreased,VGLUT 2 expression increased remarkably (both P<0.05).Compared with mod-el group,escape latency of positive drug group and in high-dose group decreased significantly (P <0.01),expression of EAAT3 in positive drug group and all ZGJTJYF groups increased(P<0.05),and VGLUT2 expression in positive drug group and high -dose group decreased significantly (P<0.05 ). Conclusion Zuogui Jiangtang Jieyu Formula can improve the disorder of EAAT3 expression and VGLUT2 expression in hippocampal astrocytes of diabetes mellitus rats with depression.
