进行性肌营养不良是进行性疾病。它可以分为几种类型,其中,强直性肌营养不良是较常见的一种,其临床表现为进行性肌强直、肌萎缩和肌无力,严重者出现肢体瘫痪。目前,该病的发病机理尚不明了。关于进行性肌营养不良的超微结构研究国内已有报道,但是强直性肌营养不良超做结构的报道很少。本文对两例典型的强直性叽营养不良患者的腓肠肌进行了超微结构的观察和研究。经神经内科临床诊断为强直性肌营养不良患者两例,一例男性,38岁,另一例女性,28岁。于患者右侧腓肠 Progressive muscular dystrophy is a progressive disease. It can be divided into several types, of which, ankylosing muscular dystrophy is a more common one, its clinical manifestations of progressive muscle rigidity, muscle atrophy and weakness, severe cases of limb paralysis. At present, the pathogenesis of the disease is not yet clear. Ultrastructural studies on progressive muscular dystrophy have been reported in China, but there are few reports on the ultrastructure of muscular dystrophy. In this paper, we observed and studied the ultrastructure of gastrocnemius muscle in two typical cases of tonic dystrophy. Two cases of orthopedic muscular dystrophy were diagnosed clinically in neurology, one male, 38 years old and the other female, 28 years old. On the right side of the patient sural
