Intracellular K+/Na+ ratios of erythrocytes of various mammalian species are known to differ markedly. We have measured ATP, K+, Na+, Mg2+, H2O contents of erythrocytes of twelve mammalian and three avian species. Our results indicate that the intracellular ATP concentration in erythrocytes of different species is in close positive correlation with the K+/Na+ ratios (linear correlation coefficient, r = 0.852). Furthermore, ATP levels in erythrocytes of individual sheep with different potassium concentrations correspond with their K+/Na+ ratios (r = 0.747). Intracellular magnesium concentrations also correlate with ATP concentrations in erythrocytes of different species (r = 0.629) and in different sheep (r = 0.549).
已知各种哺乳动物红细胞内的钾离子/钠离子比例存在显著差异。我们测量了12种哺乳动物和3种鸟类红细胞中的ATP、钾离子、钠离子、镁离子、水含量。我们的结果表明，不同物种红细胞内的ATP浓度与钾离子/钠离子比例呈密切正相关（线性相关系数，r = 0.852）。此外，不同钾离子浓度的个体绵羊红细胞中的ATP水平与其钾离子/钠离子比例相对应（r = 0.747）。不同物种红细胞内的镁离子浓度也与ATP浓度相关（r = 0.629），在不同绵羊中也是如此（r = 0.549）。
