自1957年发现用微量的硒可以预防大鼠的实验性肝坏死以后,不断有人报导硒缺乏与动物某些疾病的发生有关。近来更进一步着眼于探讨硒与人体健康的关系。我队自1969年冬季开始连续在黑龙江及四川克山病病区进行口服亚硒酸钠的现场预防观察。我们依靠各级党组织的领导,在各级卫生机构和广大赤脚医生、贫下中农的热情支持和协作下,掀起了大规模口服亚硒酸钠预防克山病的群众运动,目前已初步看出了亚硒酸钠的预防效果。为了探索病区内外环境是否处于低硒水平,有必要首先建立一种能够测定生物材料中微量硒的方法。 Since it was discovered in 1957 that traces of selenium can prevent experimental hepatic necrosis in rats, it has been reported that selenium deficiency has been linked to the development of certain animal diseases. Recently, we have further looked at the relationship between selenium and human health. My team since the beginning of winter 1969 in Heilongjiang and Keshan disease in Sichuan oral sodium selenite site observation. We have relied on the leadership of party organizations at all levels and started the mass movement of large-scale oral prevention of Keshan disease with sodium selenite under the enthusiastic support and collaboration of health institutions at various levels and the majority of barefoot doctors and poor peasants. We have now tentatively seen The preventive effect of sodium selenite. In order to explore whether the environment inside and outside the ward is at a low level of selenium, it is necessary to first establish a method that can measure trace amounts of selenium in biological materials.
