| 中文摘要 |
| 对陕西渭北高塬的调查研究证明,大骨节病发病率不同的相邻村庄内,居民发中的9种重要生命元素,唯硒的含量与各村居民患病率呈极显著的负相关。同时,该病流行地点的人发中各元素含量唯硒低于国内外健康人的发硒水平.通过对病区内不同地貌环境的土壤及饮水类型分布等项研究,阐明了重、中、轻病村交错分布的人体硒低的原因,这对大骨节病的产生与环境通过食物链导致人体硒低有关又再次提出一些新的依据。 |
| 英文摘要 |
| It has been demonstrated from the results of survey and study in the Kaschin-Beck disease occuring region, loess plateau, Shanxi province, that only the content of Se, one of the nine essential elements detected by X-ray in the children's hair shows a significant negative correlation with the percentage of incidence of the disease among neighbouring villages. The average Se content in human hair of disease point is lower than that of the people living in disease free areas at home and abroad. through the study on different types of soil and water in the environment of various topography, the cause for the distribution of light, medium and severe points of incidence and the low Se level in human body were explained. All of the results mentioned above provide a new scientific basis for the hypothesis that the incidence of K. B. D is related ro the low level of Se resulted from the low Se environment through food chain. |
