【摘要】 Ｗｉｓｔａｒ大鼠３０只，雌雄各半分层均匀分为非病区粮组、病区粮组和病区粮补相组（１００ｍｇ／ｋｇ），分别喂以克山病非病区粮和克山病病区粮，实验期为４个月。病区粮养大鼠红细胞还原高铁血红蛋白的能力，ＮＡＤＨ—细胞色素ｂ_５高铁血红蛋白还原酶活力均低于非病区粮组。病区粮补钼可升高此酶活力，提高红细胞还原高铁血红蛋白的能力，在一次性失血的应激情况下，程度达到显著。病区粮补钼（１００ｍｇ／ｋｇ）对红细胞谷胱甘肽过氧化物酶活力无明显影响。更多还原

【Abstract】 Rats were fed on grains from Keshan disease endemic and nom -endemic areas for four months. The NADH-cytochrome b₅ methemoglobin reductase activity and reductive rate of methemoglobin induced by sodium nitrite in erythrocytes of rats in non-endemic group were higher than those of endemic group, although no significant difference was observed. Treatment of bleeding resulted in considerably significant differences in NADH-cytochrome bs methemoglobin reductase activity and vitamin C content between the endemic and molybdemum supplemented group. Supplementation of molybdenum had no effect on glutathione peroxidase activity.更多还原
