以非病区粮对照、克山病病区粮及其添加豆油（６０ｇ豆油／ｋｇ饲料）饲料喂养大鼠７０ｄ，测定各组织中维生素Ｅ及血浆中脂质过氧化物含量。结果显示：无论是病区粮饲料组，还是非病区粮饲料组，在饲料中添加豆油后，动物血浆中α－生育酚（α－Ｔｏｃｏｐｈｅｒｏｌ）含量均增加，而心肌线粒体中α－Ｔｏｃｏｐｈｅｒｏｌ含量则下降，肝线粒体中α－Ｔｏｃｏｐｈｅｒｏｌ和γ－Ｔｏｃｏｐｈｅｒｏｌ含量均下降，红细胞膜中α－Ｔｏｃｏｐｈｅｒｏｌ含量亦有降低趋势。另外，饲料中长期添加豆油，可使大鼠血浆中脂质过氧化物含量显著增加。说明，随着多不饱和脂肪酸（ＰＵＦＡｓ）摄入量的增加，膜系统α－Ｔｏｃｏｐｈｅｒｏｌ的消耗量亦增加，ＰＵＦＡｓ长期负荷，可使饲克山病病区粮（低硒低维生素Ｅ）饲料动物体内的抗氧化能力下降。
The non-ward food control, Keshan disease ward and its added soybean oil (60g soybean oil / kg feed) feed 70d rats were measured in each tissue vitamin E and plasma lipid peroxidation levels. The results showed that α-Tocopherol content in plasma of animals was increased, while α-Tocopherol content in myocardial mitochondria The content of α-Tocopherol and γ-Tocopherol in liver mitochondria decreased and the content of α-Tocopherol in erythrocyte membrane also decreased. In addition, the long-term feed soybean oil, can rat plasma lipid peroxide levels increased significantly. The results showed that with the increase of polyunsaturated fatty acids (PUFAs) intake, the consumption of membrane system α-Tocopherol also increased, and the long-term load of PUFAs could make the food (low selenium and low vitamin E) The body’s antioxidant capacity decreased.
