近年来,我们对克山病病区粮食进行了实验研究工作,初步看到在克山病病区产的粮食中,较普遍地存在着某种能加重心肌损伤的因素。这种因素在一般情况下作用不明显,而在亚硝酸钠协同作用下,则容易显露出其致病作用,以致造成明显心肌坏死,和非病区产的粮食相比有明显的差别。 克山病病区粮食中这种加重心肌损伤因素的本质是什么?它和克山病病因之间的关系如何?它和亚硝酸盐以及其他一些因素之间有什么关系?怎样才能消除它的有害作用?这些都
In recent years, we conducted an experimental study on the food in Keshan disease ward, and initially found that there is a more common factor that can aggravate myocardial injury in foodstuff produced in Keshan disease endemic area. This factor is not obvious under normal circumstances, and in the synergistic effect of sodium nitrite, it is easy to reveal its pathogenic role, resulting in significant myocardial necrosis, and non-disease-producing food compared to a significant difference. What is the nature of this aggravating factor of myocardial damage in food of Keshan disease? What is the relationship between it and the cause of Keshan disease? What is the relationship between it and nitrite and other factors? How can we eliminate its Harmful? These are all
