In thalassemia major (TM) one third of patients suffers from muscle wasting, weakness and cramps. Six patients with TM were studied. All had muscle wasting and proximal weakness; serum levels of vitamin E were low (0.6-7.0 micrograms/dl) while CPK, LDH and aldolase were normal. EMG revealed low-amplitude short-duration polyphasic potentials in 3 patients and normal activity in 3 others. Nerve conduction velocities were normal in 3 patients studied. On muscle biopsies, moderate variation in fiber size with fiber atrophy and preponderance of type 1 fibers were discovered. Our findings confirm the existence of nonspecific myopathic changes in TM. Chronic vitamin E deficiency should be considered in the pathogenesis of the myopathy in TM.

Clinical and biochemical responses were studied after taking the measures to prevent nutrition muscular dystrophy in young cattle in the given ecological conditions. Analyzing the biological material (blood, hair, feed, soil), we found the sufficiently high saturation of heifer organisms with the microelement selenium and on the contrary, vitamin E deficiency. Sensitive indicators of the break-down of muscular tissue were the enzymes aspartate aminotransferase (AST), alanine aminotransferase (ALT), and mainly creatinine kinase (CPK): the activities of these enzymes increased significantly after the heifers had been driven to pasture. The stay of animals in the run to get them used to the physical load before going to the pasture was not found to be a sufficient measure to prevent muscular nutrition myodystrophy if the animals had not been administered vitamin E and selenium supplements. Of the one hundred heifers we examined, seven animals began to show the signs of nutrition muscular dystrophy; none of these animals had been administered vitamin E and selenium supplements.
