The protective effects of chloride channel blockers on the cultured hippocampal neuronal apoptosis induced by NO in rats / 中国药理学通报

ABSTRACT

Aim To observe the protective effects of SITS and DIDS,two kinds of chloride channel blockers,on hippocampal neuronal damage induced by NO in culture.Methods The cultures were divided into three groupscontrol group,NO treatment group,NO treatment plus chloride channel blocker group. The cultures were detected with the methods of morphological stain (Hoechst 33258),and the apoptotic neurons and neuronal viabilities were observed through MTT quantitative analysis. The activated caspase-3 was analyzed with western blot.Results There were significant protective effects of SITS and DIDS on neuronal damage with dose-dependence.Conclusions Chloride channel blockers have some protective effects against neuronal injury induced by NO.
