The effect of acute potassium infusion on renal tubular reabsorption of potassium by magnesium-deficient and pair-fed control rats has been studied by the recollection micropuncture method. During potassium chloride infusion, the amount of potassium remaining in the distal tubule is lower in magnesium-deficient than in pair-fed rats. This could be due to a reduction in potassium secretion or to an enhancement of potassium reabsorption. The present study demonstrates enhanced renal potassium retention in the magnesium-deficient rat, and is in contrast to previous reports of renal potassium wasting in this circumstance.
通过回收微穿刺法研究了急性输注钾对缺镁大鼠和配对喂养的对照大鼠肾小管钾重吸收的影响。在输注氯化钾期间，缺镁大鼠远端小管中剩余的钾量低于配对喂养的大鼠。这可能是由于钾分泌减少或钾重吸收增强所致。本研究表明缺镁大鼠肾脏对钾的潴留增强，这与之前关于这种情况下肾脏钾流失的报道形成对比。
