若尔盖县大骨节病分布特征及其与地质环境的关系

大骨节病是一种地方性、变形性骨关节病。国内外学者历经160年的研究,病因假说上百种,但至今仍无定论。若尔盖县是中国大骨节病发病率较高的病区之一,通过在病区开展野外调查、岩土水样测试等工作,本文总结了该区大骨节病分布特征和自然与地质环境特征,探讨了大骨节病分布与地层岩性、土壤、地形地貌、饮水水源等地质环境的关系。研究表明:基岩岩性及其土壤母质成分是影响病情分布的基本因素;病区土壤中Se、Mo、Ba等元素含量较非病区低,N、P、Pb、S元素含量高于非病区;饮用地表水中的矿化度、硬度、腐殖酸含量病区与非病区差异不显著,病区硒含量低于轻、非病区;大骨节病的致病影响因素复杂,除与岩、土、水地球化学环境因素有关外,亦与饮食结构等因素有关;大骨节病与地质环境关系密切,其病因需进一步探索。

Distribution characteristics of Kaschin-Beck disease in relation to geological environment of Zoige County

Kaschin-Beck disease is a local endemic osteoarthritis disease. In the past 160 years, experts both in China and abroad have conducted much research work in this aspect and put forward hundreds of hypotheses on the cause of this disease; nevertheless, no final conclusion has been reached. Zoige County is one of the areas in China where the incidence of Kaschin-Beck disease is relatively high. Based on field investigation, geotechnical water sample test and some other researcher work conducted in the disease...
