Abstract:
Objective To investigate the effects of pyrrolidine dithiocarbamate(PDTC) on aquaporin-9(AQP9) expression and brain edema around the hematoma in experimental intracerebral hemorrhage(ICH).Methods 128 SD rats were randomly divided into four groups: normal group,control group,ICH group and PDTC group.According to Rosenberg's methods,the models of experimental ICH were established.The rats in PDTC group were received PDTC intraperitoneally 2 h later.The brain weight column(BWC) at different time point was calculated by gray-wet method,and the expression of AQP9 was examined by immunohistochemistry.Results The BWC and expression of AQP9 in hematoma side of ICH begin to increase 4 h after ICH,peaked at 72 h,and decreased 120 h later.The BWC in opposite side of hematoma also increased 4 h after ICH and peaked at 72 h.Compared with control group,the BWC and expression of AQP9 in ICH group were higher,especially in hematoma side of brain(all(P
