Changes in Total Fiber Numbers of Disused Soleus Muscle on Rats

In this sutdy, by use of technique that was modified from Morey method, we discussed the histological influence on the soleus muscle of the rats caused by disuse. This study is characterized by the calculating of total numbers of muscle fibers. ST(slow-twitch)and FT(fast-twitch)fibers in total muscular cross-sectional area were classified by their difference in intensity of staining of actomyosin adenosinetriphosphatase(myosin ATPase).
