本文研究了蛋氨酸对饲克山病病区粮动物心肌的保护作用。结果表明,在病区粮饲料中加入0.4%DL-蛋氨酸,可使动物全血和组织中谷胱甘肽过氧化物酶活性升高,使心肌和肝脏中脂质过氧化物酶含量下降,对动物有一定的保护作用。但是,无论是病区粮饲料中加入蛋氧酸,还是同时加入蛋氯酸和亚硒酸钠,都未能明显减轻由亚硝酸钠所引起的心肌坏死。提示蛋氨酸的作用主要是通过改善硒代谢的途径而实现的。 In this paper, the protective effects of methionine on myocardial infarction in Keshan disease were studied. The results showed that the addition of 0.4% DL-methionine to the wad feed could increase the activity of glutathione peroxidase (GSH-Px) in whole blood and tissues of animals and decrease the content of lipid peroxidase in myocardium and liver Animals have some protection. However, neither the addition of egg yolk to the ward feed, nor the addition of both hydrochloric acid and sodium selenite, significantly reduced myocardial necrosis caused by sodium nitrite. Prompted the role of methionine is mainly achieved through the improvement of selenium metabolism pathway.
