用克山病低硒病区粮及其加硒粮分别喂养断乳大白鼠,12周后,腹腔注射~3H-亮氨酸10μci/100克体重,观察~3H参入晶体蛋白量。测出加硒组参入晶体蛋白量为每分551.7±123.8闪烁数/10mg蛋白,非常显著的(P<0.01)大于病区粮组(每分390.3±83.8闪烁数/10mg蛋白)。晶体中谷胱甘肽(GSH)含量及裂隙灯检查晶体透明度,两组无差别。 Weak rats were fed with Keshan disease and selenium-deficient diet and selenium-enriched grain. After 12 weeks, ~ 3H-leucine 10μci / 100g body weight was injected intraperitoneally. The amount of ~ 3H incorporation into crystalloid was observed. It was found that the amount of crystal protein incorporated into the selenium group was 551.7 ± 123.8 scintillation / 10mg protein per minute, which was significantly (P <0.01) greater than that in the ward (390.3 ± 83.8 scintillation / 10mg protein). Crystal glutathione (GSH) content and slit lamp check crystal transparency, no difference between the two groups.
