Femal rats were ovariectomized to build the model of osteoporosis, and then treated with Chinese drugs and stilbestrol respectively for 3 months. The results showed that both Chinese drugs and stilbestrol prevented the BMD, RBS and BTV from further declining in osteoporotic rats; but could not raise the BMD, RBS and BTV that had declined.

用卵巢切除的方法建立大鼠骨质疏松模型，然后对模型分别给乙烯雌酚或中药治疗3个月后发现，乙烯雌酚或中药治疗可以阻止股骨密度，抗弯强度和胫骨骨小梁体积的下降，但两种药物均不能使已经下降的股骨密度、抗弯强度和胫骨骨小梁体积升高。

Ethylene increased CaM content in tomato and strawberry fruits, which was promoted by additional Ca〓 and inhibited by blocking Ca〓 channel or chelating extracellular Ca〓. The results indicated that ethylene-inducd CaM accumulation was dependent on changing of cytoplasmic Ca〓 concentration.

乙烯促进草莓和番茄果实CaM增加，外加Ca〓促进这一作用，相反，阻断钙通道或减少胞外Ca〓均能抑制这一作用，表明乙烯对CaM的诱导依赖于细胞Ca〓浓度的变化。

CPZ and TFP inhibited ethylene-induced increase in activity of Ca〓-ATPase located in microsomal membrane in tomato and strawberry fruit, which indicated that 1 CaM involved in inducing of ethylene on Ca〓-ATPase; 2 the enzyme was regulated by CaM.

钙凋素拮抗剂CPZ和TFP能抑制乙烯诱导番茄果实和草莓果实微粒体膜Ca〓-ATPase活性，这表明CaM参与乙烯对该酶的诱导以及该酶活性受CaM的调节。

The results showed that gradients of radial velocity and temperature were larger due to viscous sublayer near the wall of reactor tube.
