本文通过对克山病区及非病区主粮小麦、玉米中氨基酸的对比分析,探讨氨基酸含量与克山病的发病关系。从所测的17种氨基酸结果表明:小麦及玉米中的氨基酸含量,病区均低于非病区;小麦中以蛋氨酸含量最低、半胱氨酸次之,玉米中以半胱氨酸含量最低,蛋氨酸次之,这说明进入生物体内含硒氨基酸(蛋氨酸、半胱氨酸)是缺乏的。还证实粮中氨基酸含量多寡受产地生态环境的影响。病区人体从食物链中摄取需要的氨基酸及其营养物含量不足与克山病的发病有密切关系。
This article through the Keshan ward and non-ward staple foods wheat, corn amino acid comparison analysis of amino acid content and Keshan disease incidence. The results of the 17 amino acids tested showed that the content of amino acids in wheat and maize were lower than those in the non-endemic area, the lowest in methionine, the second in cysteine, and the lowest in cows in maize , Followed by methionine, indicating that the selenium amino acids (methionine and cysteine) entering the organism are deficient. Also confirmed that the amount of amino acid content in the origin of the ecological environment. Ward intake of the human body from the food chain of amino acids and nutrients needed and Keshan disease is closely related to the incidence.
