Abstract:AIM: To investigate the possible protective effects of carnosol on liver injury induced by intestinal ischemia reperfusion (I/R).
METHODS: Rats were divided randomly into three experimental groups: sham, intestinal I/R anD肉鼻溶胶处理(每种n = 18)。肠I/R模型是通过夹紧上肠系膜动脉1小时来建立的。在肌肉醇治疗组中,手术在手术前1小时进行手术,腹膜内给药3毫克/千克肉瘤。再灌注后2、4和6小时,将大鼠杀死,并获得血液,肠和肝组织样品。研究了肠和肝组织学。测量了天冬氨酸氨基转移酶(AST),丙氨酸氨基转移酶(ALT)和白介素(IL)-6的水平。分析了肝组织超氧化物歧化酶(SOD)和髓过氧化物酶(MPO)活性。通过免疫组织化学分析和蛋白质印迹分析确定肝间细胞间粘附分子-1(ICAM-1)和核因子Kappab(NF-KAPPAB)。
sub_abstract_label“>结果: 。血清AST和ALT水平的显着增加。 I/R后,肝组织中SOD的活性降低,这是通过肉骨胶预处理增强的。 In addition, compared with the control group, carnosol markedly reduced liver tissue MPO activity and serum IL-6 level, which was in parallel with the decreased level of liver ICAM-1 and NF-kappaB expression.
CONCLUSION: Our results indicate that carnosol pretreatment attenuates liver injury induced通过肠道I/R,归因于NF-kappab途径的抗氧化作用和抑制。
