Abstract:
Objective:To explore the intramuscular nerve effect on the recovery of lacerated muscle. Methods:thirty (30) healthy New Zealand rabbits were involved in the study and randomly divided into groups A and B.The right musculus rectus femoris of the animal was chosen as the lacerated skeletal muscle model with the contralateral muscle as sham control. Group A underwent muscle laceration with the intramuscular nerve microsurgical repaired and muscle repaired;group B only with muscle repaired. After a postoperative period of 28weeks,measured the muscle wet weight and the muscle strength of musculus rectus femoris by electrical stimulation test and observed the change of morphology by Hematoxyline/eosin stain,Masson stain,NADH-TR stain and mATPase stain. Compared the difference of two groups through t-test and ANOVA to decide the effects of intramuscular nerve effect on muscle injury and repair. Results:At 28 weeks postoperative,Compared with the controls,wet weight and isometric contraction of musculus rectus femoris reduced in the intramuscular neurotmesis group (P
