在克山病病因研究中,不少资料涉及了硫的问题。根据资料报导(1—11),多数认为病区水中硫酸根含量低于非病区。病区土壤中硫含量也低于非病区(11)。因此曾认为上述现象是研究克山病病因的一个线索,设想克山病的发生与饮水中硫酸根的缺乏可能有关。有的单位还进行了硫酸改水预防克山病的观察。为了探讨克山病病区人群是否有缺硫的情况存在,我们对克山病病区和非病区人群饮食、尿和粪中硫含量及平衡状况进行了初步研究,现将结果报告如下。
In the etiology of Keshan disease, a lot of information on the issue of sulfur. According to the data reported (1-11), the majority think the water content of sulfate in the ward is lower than non-ward. Sulfur content in ward soil is also lower than in non-ward (11). Therefore, we have thought that the above phenomenon is a clue to study the etiology of Keshan disease. Suppose the occurrence of Keshan disease may be related to the lack of sulfate in drinking water. Some units also carried out sulfuric acid to prevent water Keshan disease observation. In order to investigate whether there is deficiency of sulfur in the population in Keshan disease area, we conducted a preliminary study on the sulfur content and balance in diet, urine and faeces of Keshan disease patients and non-disease patients. The results are reported as follows.
