Magnesium skeletal (myocardium and gastrocnemius) content has been studied in rats supplemented with 30 mM dissolutions of Mg2+, Na+, Ca2+ and K+ in drinking water, for 7 or 30 days. In both muscles, the ingestion of Mg2+ for 30 days increased Mg2+ content, while Ca2+ and K+ supplementation caused a significant drop. The increase in Na+ ingestion reduced Mg2+ content in gastrocnemius. There were no significant differences between control and animals supplemented for 7 days. These results suggest that, in the case of supplementation situations, the control mechanisms of the Mg2+ tissular content have a lower gain than those of Na+ and K+ of one order of magnitude.
研究了在饮用水中添加30 mM Mg2+、Na+、Ca2+和K+溶液7天或30天的大鼠骨骼（心肌和腓肠肌）中的镁含量。在这两种肌肉中，摄入Mg2+ 30天会增加Mg2+含量，而补充Ca2+和K+会导致显著下降。摄入Na+增加会降低腓肠肌中的Mg2+含量。对照组和补充7天的动物之间没有显著差异。这些结果表明，在补充的情况下，Mg2+组织含量的控制机制的增益比Na+和K+的控制机制低一个数量级。
