摘要: 目的 观察实验性大鼠脑室出血后,不同部位脑组织热休克蛋白70(heat shock protein 70,HSP70)表达的差异。方法 18只成熟雄性SD大鼠随机均分为正常组、对照组和模型组,采用侧脑室注血法制备大鼠脑室出血动物模型,然后用酶联免疫吸附方法制作热休克蛋白70组织切片,在显微镜下直接计数阳性细胞;采用干湿重法计算脑含水量。结果 模型组大鼠脑组织HSP70阳性细胞数和含水量明显高于正常组和对照组(P分别为0.015和0.013),而且HSP70阳性细胞主要分布于皮层和皮层下,室周也有表达。结论 大鼠脑室内出血可引起远隔部位的皮层和皮层下组织HSP70的高度表达。

Abstract: Objective To observe the expression differences of Heat-shock Protein 70 (HSP70) in braintissues in rat model of intraventricular hemorrhage (IVH).Methods Eighteen matured-male SD rats were divided equally into normal, control and modelgroup. The rat model of IVH, prepared by blood injecting into lateral cerebral ventricle directly,The tissue slice of HSP70 was made by enzyme linked immunosorbent assay. The HSP70 positivecells were calculated by microscope directly. Water content of brain tissue was calculated by drywetweight method.Results The HSP70 positive cells and water content of brain tissue in model group were morethan that of the normal or control groups(26.4 vs 2.4, 3.2; 55.33 vs 45.26, 48.38; P <0.05 andP <0.01, respectively), and the expression of HSP70 appeared in cortex and subcortex areas mainly,also appeared in periventricular tissues.Conclusion IVH of rat model can induce a high expression of HSP70 in cortex and subcortex.
