摘要
大鼠用3％凝固汽油(0.6ml/10cm^2)于脱毛的背部造成20％BSA的Ⅲ°烧伤以后,补给正常生长需要量的维生素E(VE)0.2mg·100gbw^(-1).d^(-1),满足不了体内的需要。血清和肝脏VE的含量低于补给同样剂量的正常对照组,但血浆LPO却高于正常对照组。伤后14天,组织形态学检查可见到胸腺萎缩,皮质变薄,细胞皱缩,脾脏生发中心减少,睾丸萎缩,精子和精母细胞减少。当伤后补给VE的剂量增加到2mg·100gbw^(-1)·d^(-1)时,不仅血清和肝脏VE含量明显升高,而且血浆LPO含量也降到正常对照组水平;同时胸腺、脾脏和睾丸的组织形态学也接近正常对照组。
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.
