摘要
为研究TNFα、IL6在肝再生中的作用,我们制备了大鼠70%肝切除后肝再生的模型,以增殖细胞核抗原(PCNA)的免疫组织化学染色作为肝再生的指标,对其TNFα、IL6的水平进行了检测。结果显示:PCNA在肝切除后残存肝组织中的表达明显升高,于手术后24小时达高峰。手术后3小时,假手术组和肝切除组血中TNFα和IL6的水平均有升高,但假手术组很快恢复至正常,而肝切除组血清TNFα和IL6的水平继续升高,并于术后12小时达高峰(P<005)。研究提示:TNFα。
In order to determine the effect of TNF α and IL-6 in liver regeneration after partial hepatectomy, the model was established by partial hepatectomy. Liver regeneration was assessed by immunohistochemical staining of proliferating cell nuclear antigen (PCNA). Serum TNF α and IL 6 levels were measured with ELISA. The results showed that the expression of PCNA was increased in remnant liver tissues and reached the highest beak 24 hours after partial hepatectomy. The percentage of positive cells was as high as 54%. The levels of TNF α and IL 6 were higher in groups of PH than those in groups of sham operation. The levels of TNF α and IL 6 increased gradually and reached a maximum level at 12 hour after PH. We conclude that PCNA is an important index of cell regeneration and TNF α and IL 6 play an importent role in cell proliferation.
