摘要
应用牛磺胆酸钠诱发大鼠急性出血坏死性胰腺炎并发肺损伤模型,动态观察血中TXB_2、6-酮-PGF_1a及LPO含量变化并观察川芎嗪的影响。结果表明:随着肺损伤程度加重,血浆TXB_2含量、TXB_2/6-酮-PGF_1a比值,LPO含量渐增高,肺系数值也增加;川芎嗪能显著降低TXB_2和LPO含量,稳定TXB_2/6-酮-PGF_1a比值,降低肺系数值,改善肺组织病理形态变化,从而提高存活率。
Changes of PGI_2,TXA_2 and LPO levels and the effects of tetramethylpral-zine were studied in a model of lung injury following sodium taurocholate-inducedacute haemorrhagic necrotizing pancreatitis in rats. The results suggested that followed thedeepening of lung injury the value of plasma TXB_2、TXB_2/6-Keto-PGF_1a and SerumLPO as well as lung index were elevated progressively. Tetramethylpraizine caused amarked decrease in both the level of TXB_2,ratio of TXB_2/6-Keto-PGF_1a,and the lungindex. It improved the pathologic changes and survival rate. It was concluded that TxA_2,PGI_2 and oxygen free radicals play an important role in the pathophysiology Of lunginjury in acute haemorrhagic necrotizing pancreatitis in rats and tetramethylpraizine hastherapeutic effects in that case through maintaning the balance of TXA_2 /PGI_2 andscavenging oxygen free radical.
