The gene expression of the α1,α2,α3 and β1 isoforms of sodium pump at both mRNA and protein levels were reduced markedly. Only the effect of verapamil on reducing intramitochondrial total calcium concentration was observed.

地高辛抗血清呈剂量依赖性地显著降低心肌组织内洋地黄素水平，恢复细胞膜钠泵和Ca(上标 2+)-Mg(上标 2+)-ATP酶活性，降低线粒体总钙浓度，上调钠泵α1、α2、α3和β1亚基mRNA及蛋白水平的基因表达。

Suppose there exist a strictly increasing function Φ: 0,∞→

若存在严格增加函数Φ：[0，∞]→0，∞，Φ(0)=0，jx(下标 n+1-x∈Jx(下标 n+1-x使得〈T(上标 n-1)x(下标 n+1)-T(上标 n-1)x， jx(下标 n+1-x〉≤k‖x(下标 n+1)-x‖^2-Φ‖x(下标 n+1-x‖，n≥1，x是T的不动点，在对参数的一些限制条件下，本文证明了迭代序列｛x｝强收敛于非自映象T的不动点x，其目的是把对渐近伪压缩映象的迭代结果推广到渐近伪压缩非自映象上，从而推广了以前的结果。

Ca(superscript 2+), and Ba(superscript 2+) has obvious role to increase its activity.

Ca(上标 2+)、Ba(上标 2+)对提高酶活力具有明显作用。

This indicated that reduction environment in sediment was dominated by Fe(superscript 3+) but not.

这说明沉积物中是以Fe(上标 3+)的还原为主，而非SO(上标 2-下标 4)。

This showed that the main peak position of the transmission light is between 530-540 nm, and the color saturation is about 80%. The dense green color of the uvarovite sample is caused by its higher color saturation. The theoretical analysis of the mechanism of the green coloring of uvarovite indicates that the transition of 3d-orbital electron in the Cr(superscript 3+) is responsible for the green color.

采用紫外－可见光分光光度计对样品进行吸收光谱测试，对其颜色指数进行了定量分析，所得样品颜色的主波长为530~540 nm，饱和度为80%左右，进而分析了钙铬榴石的颜色主要由Cr(上标 3+)引起，其呈色机理归因于Cr(上标 3+)的d轨道电子跃迁。

The coordination chemistry of Cu(superscript 2+) and Zn(superscript 2+) in the melanin from testae of Prunus armeniaca var. ansu was investigated to lay a foundation for utilization of the melanin and other phytomelanins.

研究山杏种皮黑色素与Cu(上标 2+)和Zn(上标 2+)络合的相关性质，为山杏种皮黑色素以及其他植物黑色素的开发利用提供依据。

The degree of substitution between Cu(superscript 2+) and Zn(superscript 2+) is increased with increasing Cu(superscript 2+)/Zn(superscript 2+) entering crystal lattices of Zn5(CO3)26/Cu2(CO3)2, and the ratio of copper to zinc in Rosasite and Aurichalcite is unchangeable.

随着Cu(上标 2+)/Zn(上标 2+)进入Zn5(CO3)26/Cu2CO32晶格，离子同晶取代量增加，催化剂前驱体中形成了固定铜锌比的锌孔雀石和绿铜锌矿物相。

The P. caudatum were cultured in the straw water with different mass concn. of Cu(superscript 2+), its polysaccharide was extracted and detected by the anthrone-sulfuric method and the effect of Cu(superscript 2+) on the content of polysaccharide in P.

方法］通过用含不同质量浓度Cu(上标 2+)的稻草液培养大草履虫，提取其体内多糖，用蒽酮－硫酸法进行检测，研究Cu(上标 2+)对大草履虫体内多糖含量的影响。

The results showed: for the toxicity of two kinds of pollutants, the Cd(superscript 2+) is more poisonous that the Pd(superscript 2+). For the sensitivity to the pollutants, the P. caudatum, C cathayensi and D. japonica increase evidently in turn. The statistical analyses indicated that the single and combined toxicity effects both increase with the exposed time extended, especially for the combined toxicity (P.05), showing a marked time-effect relation. As for the single effect, ii increase prominently with Pb(superscript 2+) and Cd(superscript 2+) concentrations (P.05); But in the case of binary effect, the results showed obviously a time-effect (P.01) as well as a concentraction-effect relations.

结果表明：在同等条件下，Cd(上标 2+)对三者的致毒效应都明显强于Pb(上标 2+)；3种动物中，草履虫最敏感，而圆田螺耐受能力最强；随单一毒物浓度的增大以及暴露时间的延长，两者的致毒效应都显著增大，表现出明显的浓度－效应和时间－效应关系；二者复合作用时，对3种动物的致毒效应主要表现为与二组分的浓度比例有关。

The paper deals with the effects of Cd(superscript 2+)、Hg(superscript 2+) and their interaction on O(superscript - subscript 2)、MDA and antioxidant enzyme systems of Ceratophyllum demersum L..
