Histomorphometric alterations of muscle soleus provoked by drawn out immobilization: experimental study with wistar lineage rats
Abstract
Objective: This study has as objective to analyze the effect of joint immobilization of the soleus muscle of posterior members of rats on morphometric profile view, at periods of 21 and 45 days. Materials and methods: Ten male Rattus novergicus albinus, Wistar variety, were used, separated into two groups (group I and II), of 5 animals each, with the first group submitted to immobilization for 21 days and the second for 45 days. The experiment control was acquired from the right contralateral member of each animal. The immobilization of the left posterior member was done by adapted orthesis. The morphometric analysis of soleus was by non-serial cross sections, 8μm thick. Results: From the obtained images, the muscle fibers areas were analyzed, including the form of the fibers, comparing with the control group. In both the periods of immobilization cross sections of staple fibres had reduction of the section area, front to the comparison to its respective member has controlled, with significant important (p < 0.0001), especially it enters the experimental groups of 21 and 45 days. Conclusion: It can be concluded that immobilization to articulate of rats per 21 and 45 days modifies the section area more transversa of staple fibres of the sóleo muscle and deleterious effect of more significant the cellular components for drawn out periods.Downloads
