Effect of Caspase inhibitor on apoptosis after intracerebral hemorrhage in rats / 临床神经病学杂志

ABSTRACT

Objective To study the effect of zVADfmk(a Caspase inhibitor) on Caspase-3 activation and neuronal apoptosis after intracerebral hemorrhage (ICH) in rats.Methods ICH model was made by stereotactic infusing 50?l autologous blood into the caudate nucleus. zVADfmk was given via intraventricular injection. TUNEL staining and immunohistochemitry method were used to detect the expression of apoptosis and Caspase-3 in cerebral tissues at different time point.Results After ICH, Caspase-3 and TUNEL positive cells increased obviously in the perihematomal brain edema zone compared with the pseudo-operation group ( P
