求翻译：Le 研究也表明，和正常大鼠相比， Caspase- 3 基因敲除的大鼠脑缺血2h，再灌注48h后，TUNEL 阳性细胞密度下降了36％， 说明C aspase- 3 在脑缺血再灌注细胞损伤中发挥了重要作用是什么意思？

Le research also has shown that and normal rats, compared Caspase - 3 gene in the RAT cerebral ischemia 2H, and the Perfusion 48 H, TUNEL positive cell density declined by 36 per cent, indicating that C aspase-3 in cerebral ischemia and perfusion stem cell damage, have played an important role

The Le research also indicated that, compares with the normal big mouse, the Caspase- 3 genes knock except the big mouse brain lacks blood 2h, after again pours into 48h, the TUNEL masculine cell density dropped 36%, explained C aspase- 3 lacked the blood in the brain to pour into in the cell damage

Le study also showed that, compared with normal rats, Caspase-3 2H knockout rat cerebral ischemia reperfusion 48h, TUNEL-positive cell density decreased by 36% about cell c aspase-3 in cerebral ischemia-reperfusion injury plays an important role in
