摘要

Congenital myopathy involving the myocardium, skeletal muscle and tongue was diagnosed in 58 of 1208 aborted bovine fetuses submitted for necropsy between February 1983 and June 1994. Microscopic characteristics of muscle lesions were consistent withsegmentai nutritional myopathy. Liver vitamin E and selenium (Se) concentrations in 40 of the 58 fetuses with myopathies were assayed, and 38 (95%) had either a deficiency of vitamin E (n=27), Se (n=2) or both micronutrients (n=9). Over this time period,570 bovine fetal livers, including those from the 40 of the 58 cases with congenital myopathy, were assayed for vitamin E and Se concentrations. Vitamin E values varied from non-detectable to 57 mu g/g of dry weight (DW), and Se values from 0.05-10.96 mu g/g (DW), indicating placental transfer of both elements and fetal ability to sequester both nutrients in the liver. For 190 cases, deficiencies of liver vitamin E (n=119), Se (n=29), or both (n=42) were the only abnormal findings.
