A STUDY ON THE ADEQUATE DOSAGE OF VITAMIN E IN PREVENTION AND TREATMENT OF VISCERAL INJURY IN BURNED RATS / 营养学报

ABSTRACT

Forty-two male rats were fed with normal vitamin E( VE)requirement diet, i.e. 0.2mg?100gbw?-1d-1 for one week and then thirty-five rats were induced a 3rd degree burn of 20% BSA, another 7 uninjured rats served as normal contrsol. The burned rats were divided into 5 subgroups receiving VE at the dosage of 0.2, 1, 2, 5,10mg. 100gbw-1?d-1 respectively for 14 days. The re-ults showed that the serum and liver VE contents were lower and the serum LPO higher significantly in the burned rats as compared with the normal control,it wao also found that thymus was atrophic, the thymic cortex become thinner thymocytes constricted, and the splenic corpuscles decreased, the sperm and spermatocytes were markedly decreased with testis atrophy. Whet burned rats were fed VE, as the dosage increased to 2mg?100gbw-1?d-1, the serum and liver VE levels significantly raised and the serum LPO returned to control level. The histological changes of thymus, spleen and testes were nearly similar to the normal control rats.
