title: [Clinical studies and ultrastructure in myotonic dystrophy].
abstract: The results of clinical and ultrastructural observation on the affected skeletal muscles in myotonic dystrophy are reported. The patients were five males and four females, aged 24-51 years. The symptoms were classical, there are myotonia, muscular atrophy, weakness and other multi-systemic symptoms, etc. Electromyography shown myotonic response. The major features under electron microscope were as follows. The partial sarcomeres shown lysis; there are the sarcoplasmic pads, sarcoplasmic masses; the muscular nuclear are proliferous and its intrude. The posterior membrane of synapse are simplism, etc. The correlations between these ultrastructural changes and pathogenesis were discussed.
