The above results indicate that the release of CGRP evoked by ETX from the sensory fibbers of rat spinal cord is dependent on extracellular calcium. After entering into the cell through the N-type voltage dependent calcium channel, calcium binds to calmodulin, and triggers calcium release from intracellular calcium store by activating the caffeine-sensitive mechanism.

At the endpoint, the thymus, spleen and uterus were weighed separately; the femoral dry weight, bone-calcium, phosphor, magnesium and hydroxyproline contents of femoral were measured; the histomorphological features of bone were observed and the biochemical indexes in serum (Ca, P, ALP, TRAP, E2, BGP) were determined after the mice were given SAR at the dose of 10, 30, 90 mgkg^(-1) respectively, and were compared with the model group, the normal control and the positive control. RESULTS: The osteoporosis of high turnover type was formed with feeding retinoic acid to experimental mice. Compared with the model group, the lessening of femoral dry weight, the short femoral transverse diameter, the decrease of bone mineral and bone-hydroxyproline of SAR groups were improved.

To investigate the effects of serum calcium and phosphorus on the model of calcium-deficient laying ducks, one hundred and twenty Shan sheldrakes were allocated into normal diet, half calcium carbonate and quarter calcium carbonate groups randomly. Serum calcium and phosphorus were detected by automatic biochemistry analyzer one day before and one, three and five weeks after fed with above diets.

将120只600日龄产蛋山麻鸭随机分为正常日粮组、1/2石粉组和1/4石粉组，自动生化分析仪测定更换饲料前1 d及更换饲料后1、3、5周血清钙、磷水平，观察缺钙日粮对蛋鸭血清钙、磷的影响。

结果表明：在中性水环境中，贝体能积极地从外界水环境中吸收钙，并能旺盛地合成和分泌贝壳珍珠层及珍珠有机基质前体物质；持续的酸性水环境导致贝体的钙严重丢失，并引起珍珠质分泌细胞对有机基质前体物质的合成和分泌能力减弱；持续的碱性水环境虽能导致贝体对钙的积累，但珍珠质分泌细胞合成和分泌珍珠质有机基质前体物质的能力减弱；水环境的酸性或碱性程度越高，对珍珠质分泌细胞的合成和分泌活动的影响越大。
