本文对小鼠部分肝切除方法作了一些探讨。实验结果证明,不同体重范围的小鼠各肝叶相对重量比较恒定。切除小鼠肝左叶可以获得恒定的切除率(35.6％)。用放射性同位素标记前体参人生物大分子的方法可以明显看出,肝切除35.6％足以刺激存留肝脏再生。而且此方法操作简便,较为经济,可作为研究药物对损伤肝脏修复影响的模型。 In this paper, some methods of liver resection in mice made some discussion. Experimental results show that the different weight range of the liver relative weight of the mice is relatively constant. A constant resection rate (35.6%) was obtained by resection of the left lobe of mouse. With radioisotope labeling precursor biological macromolecules, it is clear that hepatectomy 35.6% is enough to stimulate the retention of liver regeneration. Moreover, this method is simple, economical and can be used as a model to study the effect of drugs on liver injury repair.
