Effect of disulfiram in experimentally induced vitamin E deficiency myopathy in lambs.

Abstract: Vitamin E deficiency myopathy (white muscle disease) was induced in 14 suckling lambs (2 experiments; 7 lambs/experiment) by addition of cod liver oil to the diet. Disulfiram, an antioxidant, was administered orally once each day to 8 of the 14 lambs at 2 different doses. Serum creatine kinase (CK) activity was measured weekly for 5 weeks. Increased CK activity was evident in some lambs beginning at week 3. By week 4, serum CK was abnormally increased in 5 of the 6 nontreated lambs (ie, disulfiram not given) and in 4 of the 8 treated lambs. The combined disulfiram groups had significantly lower serum CK values during the study (P less than 0.05). Serum alpha-tocopherol, measured on samples from week 5 for lambs of experiment 1, was significantly higher in treated lambs (P less than 0.01). Microscopic examination of the vastus lateralis muscle indicated that the most severe lesions, consistent with nutritional myopathy, were seen in nontreated lambs. Therefore, disulfiram may have an antioxidant effect in lambs with vitamin E deficiency.

Kyphosis in Jersey calves

Abstract: A condition of Jersey calves involving kyphosis and lordosis is described. Four calves originating from three farms, all the progeny of one bull, were necropsied. The only significant finding was a myopathy mainly affecting sublumbar muscles. The lesions were not consistent with white muscle disease or of any known myopathy affecting Jersey calves. It is likely that this condition represents a primary muscular dystrophy of genetic origin.
