本文对云南省牟定县申平村单纯克山病病区和陕北榆林县蟒坑村单纯大骨节病病区的生态化学环境进行了对比研究，表明两地生态化学环境仍处于低Ｓｅ水平，申平村人群仍有潜在型克山病病例，蟒坑村人群的骨质病变则出现很高的ｘ线阳性检出率，说明两地的致病因子仍然活跃。从生态系物质含Ｓｅ量看出，蟒坑村的缺Ｓｅ程度较申平村高。此外，单纯克山病病区申平村土壤、粮食、人发中的Ａｓ明显高于蟒坑村和非病区。为此，从Ａｓ与Ｓｅ具有拮抗作用的角度考虑，提出应进一步研究Ａｓ与Ｓｅ对克山病的复合致病作用。
In this paper, we compared the eco-chemical environment of Kashin-Beck disease in Shenping Village, Mouding County, Yunnan Province, and Kashin-Beck Disease in Wuxing Village, Yulin County, northern Shaanxi Province, which showed that the eco-chemical environment in both areas was still low , There are still cases of potential Keshan disease in the village of Shenping Village and high incidence of x-rays in the bone lesions of the python village. This shows that the pathogenic factors in the two places are still active. Seen from the ecosystem material containing Se content, python pit village lack of Se level Shen village. In addition, the As in the Keshan disease area of Shen Ping village soil, grain, human hair As is significantly higher than the python pit village and non-ward. Therefore, considering the antagonistic effects of As and Se, it is suggested that further study on the complex pathogenicity of As and Se to Keshan disease should be carried out.
