大骨节病的病因至今不明。以往调查表明,大骨节病区中,营养较差的农村儿童发病率高,罹病严重。以往的研究结果表明,大骨节病患者存在软骨细胞磷脂代谢障碍、细胞膜损伤的改变。为查明大骨节病区居民日常食品中总磷脂含量及磷脂分子种类的构成情况,我们对陕西、辽宁等地的蔬菜、粮食、肉蛋等进行了总脂质,总磷脂和磷脂分子种类含量的分析研究。 The cause of Kashin-Beck disease remains unknown. According to previous surveys, the incidence of malnutrition among rural children in Kashin-Beck disease area is high and they suffer from severe illness. Previous research results show that patients with Kashin-Beck disease phospholipid metabolism of chondrocytes, changes in cell membrane damage. In order to find out the content of total phospholipids and the composition of phospholipid molecular species in daily food of residents in Kashin-Beck disease area, we studied the contents of total lipids, total phospholipids and phospholipids in vegetables, grains and meat eggs in Shaanxi and Liaoning provinces Analysis and Research.
