摘要
作者用显微外科技术模拟兔股直肌游离移植的研究中,首次采用裂区析因设计,对移植肌收缩特性12项功能指标及各指标间的相关关系进行微机分析,发现移植肌的最大强直张力(TcT)术后1年才恢复到同体健侧水平(P>0.05),认为从双侧肌力平衡的角度看,术后1年进行功能评价比较合适.各组移植肌疲劳指数(FR)均小于25％,与正常对照侧相差都不显著(F<F 0.05,P>0.05),是本系列研究中发现3种肌纤维百分构成比无明显改变的功能学依据,因此,实验肌全肌以快肌收缩为主的特性保持不变.实验还发现FR与TcT之间存在正相关(r>r 0.01),即TcT每增加1N,FR相应提高0.12％.
The split - unit experimental design was first used in simulating free muscle transplantation by microncurovascular anastomoses on the rcctus fcmoris of rabbits , and 12 functional indices of contractile properties and the correlation between these indices were analysed with a microcomputer. The results showed that the maximum tetanic tension (TcT ) of grafted muscle returned to normal level in the same animal 1 year after operation (P>0.05 ), and , in our opinion , in view of tension balance between the two sides . this was the optimal time to appreciate the muscle function . It was found that the fatigue rate (FR ) in each group was less than 25% , and without any significant difference compancd with that in the normal control side ( F< F0.05, P >0.05 ). This was the functional evidence that the constituent ratio of 3 types of muscle fibers did not change in our scries studies . Therefore , the main character of fast contraction of the whole grafted muscles was remained the same . There was a positive correlation between FR and TcT (r>r 0.01) .i.e. whenever TcT increased by 1 N , FR increased 0.12% .
