Ulinastatin on sepsis myocardial protection of myocardial injury in rats and the effects of acetylcholine receptors and M type / 中国生化药物杂志

ABSTRACT

Objective To explore the protective effect of ulinastatin (UTI) on myocardial protection in sepsis. Methods 69 clean male SD rats were randomly divided into 3 groups normal control group, sepsis group and ustodin group. experimental rats serum troponin T (ATnT) concentration, using automatic biochemical analyzer determination of creatine kinase (AK), creatine kinase isoenzyme (AK-MB) concentration;The changes of AAh and m-aahrs levels in rat myocardial tissues were detected by enzyme-linked immunosorbent assay. Pathological changes of myocardial tissue in rats were observed by HE staining. Results The serum ATnT, AK and ak-mb concentrations in the sepsis group were significantly higher than that in the normal control group, and the indexes of the ustodin group were significantly decreased (P<0.05). The AAh level of myocardial tissue of sepsis group was significantly higher than that of the normal control group, and the AAh level was significantly decreased after the treatment of UTI, and the m-aahrs level of myocardial tissue was not significantly changed (P<0.05). Pathological histological observation showed that the myocardial tissue lesion was significantly relieved (P<0.05). Conclusion UTI can improve the degree of myocardial injury in rats with sepsis.
