Rats were fed a low calcium diet deficient in vitamin D for 14 days. Changes in alkaline phosphatase activities in odontoblasts dissected out from incisor teeth were studied biochemically. A strong increase in pNPP-ase, PPi-ase, total ATP-degradation and Ca2+- ATPase was observed in the deficient animals compared with animals fed a control diet.
给大鼠喂食缺乏维生素D的低钙饮食14天。对从切牙中分离出的成牙本质细胞中的碱性磷酸酶活性变化进行了生化研究。与喂食对照饮食的动物相比,在缺乏维生素D的动物中观察到对硝基苯磷酸酶(pNPP-ase)、焦磷酸酶(PPi-ase)、总ATP降解和Ca2+-ATP酶有显著增加。
