钙、维生素D缺乏大鼠长骨成骨细胞的维生素D受体水平

Vitamin D receptor level in osteoblasts in long bones of rats with calcium and vitamin D deficiencies

对正常、钙缺乏和维生素D缺乏的大鼠 ,观察其体外培养的长骨成骨细胞的维生素D受体最大结合容量 ,结果显示维生素D缺乏组显著低于正常组 (P <0 .0 1)。

Maximal binding capacity (B max ) of vitamin D receptors (VDR) was observed in cultured osteoblasts from long bone of the normal, calcium-dificient and vitamin D-deficient rats. The results show that B max of VDR in vitamin D-dificient group is significantly lower than that in normal group (P<0.01).
