During the titration of Ca〓CaM by La〓, the hydrid complex La〓Ca〓CaM forms as the intermediate species. La〓 can bind to calmodulin with high affinity (K〓=10nmol/L) and obvious cooperation between the two global domains. The secondary structure of La〓CaM and Ca〓CaM are highly similar, but there are obvious differences in ternary structures. Excessive La〓 changes the conformation of calmodulin greatly.

实验结果表明，La〓在钙调蛋白上的结合位点与钙离子相同；在结合顺序上La〓以较小的优势先结合在钙调蛋白的N末端；La〓Ca〓CaM是La〓与含钙的钙调蛋白作用时的主要产物；La〓强烈地与钙调蛋白结合，其解离常数约10nmol/L，各个结合位点之间存在明显的协同效应；La〓CaM与Ca〓CaM在二级结构上高度相似，但是在高级结构上有明显差异。

The sarcoplasmic reticular Ca-ATPase and the sar-colemmic Na/Ca exchanger contribute mainly to the steady state of calcium in the myoplasm.

在各种机制中，肌质网Ca-ATPase与肌膜Na/Ca交换蛋白对于维持胞内Ca~（2+）的平衡发挥主要作用。

This paper describes the determination on the activity of carbonic anhydrase (CA,EC4.2.1.1) of plant species in karst areas of Southwest China. CA was extracted from leaves of Vitex negundo. The thermostability of CA and the effects of anions and metallic ions on CA activity were investigated.

After NMDA stimulation, he concentrations of Ca~2+ and NO in both nuclear and plasma rise observably, especially in the netlike structures; the change of Ca~2+ concentration in nuclear is larger than that in plasma,however the changes of NO concentration in nuclear and plasma are similar. We also observed comparative increases of the concentration of Ca2+ and NO in neurodendrite after NMDA stimulation.

NMDA刺激后神经元细胞核和细胞质内Ca~(2+)和NO都明显升高，尤其在细胞核和细胞质内的网状结构处；细胞核内Ca~(2+)升高幅度大于细胞质，而细胞核内NO的升高幅度却与细胞质相近；另外，树突内的Ca~(2+)和NO升高也较明显。

Because the atomic affinity energy of Ca-O and Be-O is lower than Mg-O,The Ca and Be aggregating on the surface of liquid Mg will priorly combined with O,forming compact oxides of Ca,Be and alloys of elements,which prevent Mg alloys from burning.

由于Ca，Be与氧的原子亲和能低于镁与氧的亲和能，聚集在液体表面的Ca，Be将优先与氧结合，生成致密的镁与合金元素的混合氧化物，阻止镁合金燃烧。

The sulfamate moiety in the structure of topiramate is chemically related to known CA inhibitors, and in fact, topiramate inhibits CA activity. To further explore the pharmacological action of topiramate, and clarify the possibility of anti-tumor growth and metastasis of CA inhibitors and its relation with AQP1, we studied the effect of topiramate on adhesion of high metastatic prostate carcinoma to laminin, and established the spontaneous metastatic model of Lewis lung carcinoma to studied the influences of topiramate on tumor growth and metastasis and AQP1 expression in lungs and primary tumors of mice.
