METHOD:Compared the weight of regenerational liver, hepatic regeneration rate,hepatic weight/100 g body weight and mitosis index of the treatment group and control group after operation 2,7,14 days.
方法 :比较大鼠在肝大部切除后经高压氧治疗与不经高压氧治疗时于术后第 2、7、1 4d的再生肝重、肝再生度、肝重 / 1 0 0 g体重、有丝分裂指数。
The results indicated that: (1) After treatment, the mitosis index was obviously increased, the promoting effects on mitosis of prophase and metaphase cell were more significant, although there was no notable linear relationship between the increase of mitosis index and the changes of APM concentration.
结果表明 :(1)不同浓度APM处理后 ,可明显提高有丝分裂指数 ,但与APM浓度的增加无明显线性关系。
