高原鼢鼠和高原鼠兔骨骼无机化学成分的研究Ⅱ.必需微量元素

STUDIES ON THE INORGANIC CHEMICAL COMPOSITION IN SKELETONS OF PLATEAU ZOKER AND PLATEAU PIKA Ⅱ.ESSENTIAL TRACE ELEMENTS

本文报道了高原鼢鼠和高原鼠兔整体骨骼及头骨、脊柱骨和下肢骨中Ｃｕ、Ｚｎ、Ｆｅ、Ｍｎ、Ｃｏ、Ｎｉ、Ｍｏ、Ｃｒ、Ｔｉ、Ｆ、Ｓｅ和Ｇｅ１２种必需微量元素的含量，并进行了显著性差异和相关性分析。结果表明：只有Ｃｕ的含量在两种动物骨骼中没有显著性差异（Ｐ＞０．０５），其余１１种元素均有显著性或极显著性差异（Ｐ＜０．０５或Ｐ＜０．０１），其中Ｚｎ、Ｆｅ、Ｍｎ、Ｃｏ、Ｎｉ、Ｍｏ、Ｆ和Ｓｅ的含量，高原鼢鼠＞高原鼠兔，而Ｃｒ、Ｔｉ和Ｇｅ的含量，高原鼠兔＞高原鼢鼠。微量元素在头骨、脊柱骨和下肢骨中分布很不均衡。

The contents and distributions of 12 trace elements were analyzed in the whole length bone, cranium, backbone and legbone of plateau zoker (Myospalax baileyi) and plateau pika (Ochotona curzoniae) .The twelve trace elements are Cu, Zn,Fe,Mn,Co,Ni,Mo,Cr,F,Se,Ti and Ge.The results were as follows: The difference of the contents of only Cu in the skeleton of two kinds animals was not significant, the difference of another 11 trace elements were remarkable( P <0 05 or P <0 01),the contents of Zn,Fe,Mn,Co,Ni,Mo,F and Se of the plateau zokers were higher than the plateau pikas; Cr,Ti and Ge of the plateau pikas were higher than plateau zokers. The distribution of trace elements was not average in the cranium,backbone and leg bone,the trace elements were the richest in the cranium.
