3种中药对脓毒症大鼠脾脏半胱天冬酶3表达影响的对比研究

Effect of Three Traditional Chinese Medicine Compounds on Level of Expression of Caspase 3 of Spleen in Sepsis Rats

目的研究脓毒症大鼠脾脏半胱天冬酶(caspase)3表达变化以及3种中药对脓毒症大鼠脾脏caspase 3表达影响的对比。方法采用盲肠结扎穿孔(CLP)的方法造成脓毒症模型,造模成功后分成5组,造模后3、24、72 h腹腔静脉取血;采用免疫组化的方法检测脾脏淋巴细胞caspase 3阳性细胞的表达。结果脓毒症大鼠的脾淋巴细胞caspase 3表达是明显升高的,代表脾脏淋巴细胞凋亡增加,3种中药均能明显降低脾淋巴细胞caspase3表达。结论3种中药能减低脓毒症淋巴细胞凋亡,调节机体免疫。

OBJECTIVE To study the characteristic change of the expression of caspase 3 of spleen in different sepsis rats.METHODS We designed sepsis model by cecal ligation puncture,divided into five groups,sampled tissue in 3,24 and 72 h after model built,and compared the change between groups.We employed the immuno-histochemistry to examine the positive expression of caspase 3 in spleen,and examined the index of apoptosis in different groups.RESULTS The result showed that three traditional Chinese medicine compounds could significantly cut down the expression of caspase 3 in spleen lymphocyte.CONCLUSIONS The three traditional Chinese medicine compounds could decrease the apoptosis of lymphocyte,and adjust the immunity.
