破碎红纤维

线粒体肌病与其它神经肌病破碎红纤维的对比研究

A comparative study of ragged red fibers between mitochondrial myopathy and other neuromuscular disorders

6例患者中4例发现破碎红纤维（RRF），其平均比例为5.3%；超微结构观察有线粒体异常及糖原颗粒沉积，其中有2例发现有典型晶格状包涵体。

Results The average proportion of RRF was 5.3 % in 4 cases , and glycogen granule deposition and crystal include bodies in 2 cases .

结论：MGT染色发现破碎红纤维，电镜下线粒体堆积、形态异常，特别是线粒体内晶状包涵体，对本病的诊断有重要价值。

Conclusion : Histochemical MGT staining light shows RRF , accumulation of abnormal mitochondrials , especially the paracrystaline inclusion which plays an important role in diagnosis .
