克山病患者及健康人血清游离氨基酸与蛋白质含量分析

对克山病病区健康人35例、克山病人38例的17种血清游离氨基酸与蛋白质含量进行了分析,并以非病区健康人31例作对照,发现病区居民血清游离氨基酸总量、必需氨基酸、非必需氨基酸及血清蛋白质显著降低。病区健康人苏氨酸、脯氨酸、胱氨酸、异亮氨酸、酪氨酸及色氨酸降低;克山病人苏氨酸、脯氨酸、丙氨酸、胱氨酸、缬氨酸、异亮氨酸、亮氨酸、酪氨酸、赖氨酸、组氨酸及色氨酸降低。结果表明,病区居民血中处于低氨基酸低蛋白状态,此可能是克山病发病的重要条件之一。

ANALYSIS OF SERUM FREE AMINO ACIDS AND PROTEIN IN PATIENTS WITH KESHAN DISEASE AND HEALTHY PERSONS

Seventeen kinds of serum free amino acids (FAA) of 35 healthy persons in endemic area of Keshan disease and 38 patients with Keshan disease were determined and compared with 31 healthy persons in non-endemic area. It was found that mean values of total FAA, essential amino acids, non-essential amino acids and serum protein of inhabitants in endemic area of Keshan disease were significantly lower(P<0.05-0.01),that the G kinds of FAA of healthy persons in endemic area and 11 kinds of FAA of patients were significantly lowcr(P<0.05-0.01). It showed that inhabitants in endemic area were in poorer amino acids and protein nutritional condition. It is suggested that lack of amino acids and protein in serum may be important factors concerning Keshan disease.
