• 摘要：1987年4月-1989年9月对内蒙三个大骨节病村进行了连续随诊观察, 结果表明, 大骨节病病情逐年下降, 人体硒营养水平相应提高, 病情与硒营养水平之间呈显着负相关。每日由外源性食物中摄取的硒与病情呈显着负相关, 而由当地产粮、菜中摄取的硒与病情呈显着正相关, 由肉蛋类食物中摄取的硒与病情呈显着负相关, 生态环境中的硒基本无变化。增加外源性高硒食物输入病区和政变病区食物构成是控制硒反应性疾病的主要途径。

• Abstract：From April l987 to September l989,the continual and perspective stu一died on three Kaschin-Beck disease(KBD)affected areas in Inner Mongoliawere carried out,with following results:The incidence of KBD lowered withyears, while the selcnium nutritional status in human bodies raised, showingsignificant negative correlation;The selenium intaken from exogenous perday diets have negative correlation with incidence of the disease,and seleniumintaken from food and vegetables in affected areas have positive correlationwith incidence of the disease;The selenium intaken from meat and eggs perday has significant negative correlation with incidence of the disease;Sele-nium in ecological environment is almost unchanged; Adding exogenous highselenium diets to and changing in resident's diets composition in the affectedarea are the major methods rising the selenium nutritional status of humanbodies and controlling the incidence of selenium responsive diseases.
