NEUROTROPISM TO TISSUE SPECI FICITY IN NERVE REGENERATION EXPERIMENTAL STUDV ON SCIATIC NERVES OF RAT

Using the left sciatic nerves of 44 rats we studied neurotropism in nerve regeneration. The proximal and distal cut ends of the nerves were separately introduced into the ends of a specially designed silastic Y- or cross-shaped tube. Either the distal stump or a cut end of the Achilles tendon was inserted into the other ends of the tube, or was left empty. The distance between the tissue ends, nerve-to-nerve or nerve-to-tendon, was 4 mm. Four weeks later, neurofibers sprung out from the proximal stump and grew towards the distal nerve end instead of the tendon end or the vacant channel of the tube. This finding suggests that neurotropic factors may influence the direction of growth of the newly formed neurofibers. This paper discusses the mechanism of neurotropism, the effect of the distance between the cut ends of the nerve, and the choice of the silastic material.

生物传感器的研制及应用

近年来生物传感器已广泛应用于医学领域,借助于传感器,医务工作者可得知动物体内或人体内某些生物力学特征,以及疾病状态下的变化,对于体内生物力学的研究及临床某些疾病的辅助诊断,提供了科学的客观指标.例如:正常肌肉内的压力,疾病状态下压力的改变;肌肉收缩力量,关节腔内的压力,椎间盘内的压力,以及子宫腔内的压力等等,取得这些器官内压的正确数值对于探讨某些疾病的起因及防治有着不可低估的临床意义.     

前跗关节楔形截骨术治疗高弓仰趾畸形足(附20例分析)

本文对1973年以来收治的20例高弓仰趾畸形足进行了临床分析。针对畸形特点采用相应的截骨方法,对18只足进行随诊,平均随诊5年7个月,均获得优良效果。本文重点讨论以下两点:(1)高弓仰趾畸形足的畸形焦点是足纵弓的高度增加及前足下垂,其纵弓的顶点位于舟楔关节处,故在此处进行截骨是最合理的,且优于McElvenny和Caldwell的跖跗关节截骨术及Japas设计的V形跖跗关节截骨术;(2)高弓仰趾畸形足的X线测量与手术疗效有密切关系。通过对内弓角、外弓角、距跖角及跟1长度,跟5长度的测量,把畸形分为重、中、轻3度,作为决定本病治疗措施的依据。
