高原鼠兔血清无机元素含量的分析

测定分析了高原鼠兔血清电解质、无机元素、血清铁和总铁结合力, 并与人和其它实验动物的相应指标进行了比较。得出以下主要结论: 1.高原鼠兔血清电解质浓度不受生活环境和食物条件的影响, 其机体能自身调节血清离子浓度, 以维持电解质在血液中的相对衡定; 2.高原鼠兔血清铁含量与其栖息地海拔相关, 随海拔升高血清铁含量增加; 3.高原鼠兔通过增加运铁蛋白与铁的结合力作为适应高原低氧环境的方式之一。

ELECTROLYTES AND INORGANIC SUBSTANCES IN SERUM OF PLATEAU PIKA

Plateau pika (Ochotona curoniae ) is a new laboratory animal. The biological characteristics of this animal has been discovered and accumulated. The electrolytes and inorganic substances in the serum of plateau pika have been measured and analyzed . 22 wild pikas and 20 close colony pikas were used in the experiment. The important results were included as follow: (1) The concentration of electrolytes in the serum of pika does not be affected by environmental conditions that pika lives. The animal body can adjust and keep the relative constant for the concentration of serum electrolyte by themselves. (2) The iron content of serum for the pika is relative to the distribution altitude of the pika. With the increase of the habitat altitude, the iron content of serum becomes higher. (3) The total iron capacity and the saturation percentage of the transferrin with iron tended to increase with the increase of the habitat altitude. This is one of the ways for plateau pika adapting to hypoxia environments.
