摘要
目的分析西藏地区粮食中的含硒量,探讨硒与大骨节病分布的关系。方法采集西藏地区居民的主要粮食作物,用氢化物发生原子荧光法测定含硒量,结果运用SPSS软件进行t检验。结果西藏大骨节病病区内粮食硒水平显著低于非病区(P<0．01)。结论西藏地区粮食含硒量处于低硒水平,大骨节病病区的粮食含硒量显著低于非病区粮食,低硒食物摄取是西藏大骨节病的主要原因之一。
Objective To measure the selenium concentrations of grains and to investigate its relationship with Kaschin-Beck disease （KBD） distribution in Tibet. Methods Grain samples were taken from KBD areas and non-KBD areas in Tibet to be measured for their selenium concentrations. The results were analyzed by t test using SPSS. Results In Tibet, the selenium concentrations of grains in KBD areas were significantly lower than those in non-disease areas （P 〈 0.01 ）. Conclusions Selenium concentrations of grains in Tibet are low. There is a significant difference in selenium concentrations of grains between KBD areas and non-disease areas. Selenium deficiency in food intake contributes to the pathogenesis of KBD in Tibet.
