用发射光谱法测定52例扩张型心肌病患者的血硒及发硒,其含量分别为0.52±0.20μol/L和0.28±0.101 ppm,均显著低于正常对照组(血硒1.02±0.20μmol/L,发硒0.41±0.125ppm)。提示患该病时处于低硒状态。58例克山病的血硒为0.39±0.18μmol/L,发硒0.22±0.07ppm,亦处于显著低硒状态。两病低硒程度有显著差別,低硒程度似可作为两病的鉴别诊断。
The content of selenium and selenium in blood of 52 patients with dilated cardiomyopathy were 0.52 ± 0.20μol / L and 0.28 ± 0.101ppm, respectively, which were significantly lower than that of the normal control group (serum selenium 1.02 ± 0.20μmol / L, hair selenium 0.41 ± 0.125ppm). Suggesting that the disease is in a low selenium state. 58 cases of Keshan disease blood selenium was 0.39 ± 0.18μmol / L, selenium 0.22 ± 0.07ppm, also in a significantly low selenium state. Low selenium levels were significantly different, low selenium levels may seem as a differential diagnosis of two diseases.
