  • Title: Strongly succinate dehydrogenase-reactive blood vessels in muscles from patients with mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes.

    Journal: Ann Neurol; 1991 Jun; 29(6):601-5. PubMed ID: 1892363.
    Abstract:
    Intramuscular blood vessels were examined with succinate dehydrogenase stain in skeletal muscle biopsy specimens from 6 patients with mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS). Almost all arteries had large granular deposits with high succinate dehydrogenase activity in their walls. Electron microscopic examination of serial frozen sections of these biopsies showed that the smooth muscle cells of the strongly succinate dehydrogenase-reactive blood vessels contained markedly proliferated mitochondria, characteristic of patients with MELAS. The presence of strongly succinate dehydrogenase-reactive blood vessels in muscle biopsy specimens provides an important clue toward understanding the underlying pathogenetic mechanism in patients with MELAS as well as another approach to the diagnosis of this disorder.
