Abstract
The histochemical reaction pattern of porcine skeletal muscle giant myofibers for succinic dehydrogenase and the relationship to other myofiber types is discussed. Staining with hematoxylin and eosin showed giant myofibers to be basophilic, and devoid of visible striations. The usual ultrastructural banding pattern of normal myofibers was completely absent in giant myofibers. Giant myofibers showed no recognizable mitochondria or sarcoplasmic reticulum but contained numerous vacuolar structures. Nuclei of giant myofibers stained more densely than those of normal fibers and giant fibers showed nuclear proliferation in some areas. The similarity between giant myofibers and myofibers from dystrophic animals of various species is discussed. Copyright © 1978. American Society of Animal Science .
