| 摘 要： | Objective To explore the changes of the nerve fibers from median and ulnar nerves after cutting the branches of lower trunk which was repaired by the contralateral C7.Methods Forty female SD rats were divided into A, B, C and D groups randomly.In group A,the contralateral C7 root was transferred to lower trunk directly, and the posterior division of lower trunk, medial anterior thoracic nerve and the medial antebrachial cutaneous nerve were severed at the beginning of them;In group B, the contralateral C7 root was trarsferred to lower trunk directly, and the posterior division of lower trunk, medial anterior thoracic nerve and the medial antebrachial cutaneous nerve were severed at the point which was 1 cm away from the beginning of above branches;In group C, the contralateral C7 root was transferred to lower trunk directly, and the posterior division of lower trunk was severed at the beginning of it;In group D, control group.After the operation, myelinated fiber count, nerve fiber density, the percentage of the number of nerve fiber from branch accounting for that from lower trunk, nerve fiber diameter,the percentage of nerve fibers with different diameters and N Ratio were carried out to evaluate the outcome of each group.Results Myelinated fiber count, nerve fiber density, the percentage of the number of nerve fiber from branch accounting for that from lower trunk, nerve fiber diameter,the percentage of nerve fibers with different diameters and N Ratio in ulnar and median nerve, there were no difference between group A, group B and group C ( P ＞ 0.05).Conclusion After the medial anterior thoracic nerve and medial antebrachial cutaneous nerve, repaired by the contralateral C7, were severed at the beginning and at the point which was 1 cm away from the beginning of above branches, the changes of the quantity and quality of the nerve fibers from median and ulnar nerves were not significant.
