摘要: 目的: 探讨肿瘤坏死因子(TNF) 在肝缺血-再灌注损伤(HIRI) 中的作用及左旋精氨酸(L-Arg) 对其影响。方法: 选择HIRI 实验兔及肝癌手术患者, 观察血浆TNF 含量、谷丙转氨酶(ALT) 活性、肝形态学的变化及L-Arg 对上述指标的影响。结果: HIRI 期间, TNF 和ALT 明显升高(P<0.01), 两者呈显著正相关(实验兔r =0.912, P<0.01;患者r =0.535, P<0.01), 肝形态学发生异常变化。使用LArg后, 上述指标的异常变化显著减轻(P<0.05 和P<0.01) 。结论: TNF 是HIRI 的重要发病因素, LArg可通过降低TNF 减轻HIRI 。

Abstract: AIM: To explore the role of tumor necrosis factor (TNF) in rabbits and patients with hepatic ischemia-reperfusion injury (HIRI) and the effects of L-Arginine (L-Arg) on the injury.METHODS: Changes of the several parameters and the effects of L-Arg were observed during HIRI in 20 rabbits and 18 patients who were scheduled for elective hepatic surgery.The parameters included TNF, alanine aminotrasferase (ALT) and changes of hepatocytes morphologically.RESULTS: TNF content and ALT activities increased (P<0.05 and P<0.01), and the abnormal changes of hepatocytes morphologically were obvious during HIRI.There was positive correlation between the changes of TNF and ALT (rabbits, r =0.912, P<0.01 and patients, r =0.535, P<0.01) during HIRI.With the treatment of L-Arg, the abnormal changes of all parameters as above and hepatocytes morphologically were all alleviated remarkably (P<0.05 and P<0.01).CONCLUSION: TNF may be one of the primary causes for HIRI, and L-Arg can alleviate HIRI by eliminating TNF.

Key words: hepatic ischemia-reperfusion injury, tumor necrosis factor, L-arginine
