一种由心肌总Na、K、Ca含量计算细胞内含量的方法

本文建立了一种由心肌总Ｎａ、Ｋ、Ｃａ含量，通过计算得到细胞内含量的方法。首先由测定的心肌总Ｎａ和Ｋ含量计算出心肌细胞外液体积，继而算出细胞外液中Ｎａ、Ｋ、Ｃａ含量，最后得到细胞内含量。本法计算结果与其它实验方法所得结果一致，表明本法科学可靠。在目前还没有能直接测定细胞内Ｎａ、Ｋ、Ｃａ含量技术的情况下，它不失为一种较好的手段。

A METHOD OF CALCULATING INTRACELLULAR Na,K,Ca CONTENTS FROM TOTAL Na,K,Ca CONTENTS IN THE MYOCARDIUM

A method was set up by which myocardial intracellular Na,K,Ca contents can be calculated from total myocardial Na, K, Ca contents.Extracellular space was calculated from total myocardial Na,K,Ca contents,and Na,K,Ca contents in the extracellular space were then calculated.Finally,intracellular Na,K,Ca contents were calculated.The results by this method were consistent with those by other experimental methods.At present,it is impossible to measure intracellular Na,K,Ca contents directly, this method is feasible and reliable.
