title: Ultrastructure of muscular dystrophy. II. A comparative study in lambs and chickens.
abstract: The ultrastructure of the semitendonosus muscle of lambs and the pectoralis major muscles of chickens suffering from nutritional muscular dystrophy were studied. Samples of tissue from histologically normal and mildly degenerate areas were examined. Ultrastructural examination of areas that appeared apparently normal histologically, revealed lesions in the small vessels, connective tissue elements and neuromuscular elements. The possible relationship of these findings to the etiology of this disease are discussed.
