Abstract
In cold acclimated male albino rats, in the cold the diuresis, glomerular filtration rate and water reabsorption were increased. These values did not differ from the control those. The kidney cold-induced diuresis was due to the increase of the glomerular filtration rate. The kidney excretion of the sodium was decreased during the cold adaptation both in the cold and in the heat. The decrease of the sodium excretion seemed to be due to the increase of the Na+-pump capacity in the kidneys.
摘要
在冷适应的雄性白化大鼠中，在寒冷环境下，利尿、肾小球滤过率和水重吸收增加。这些值与对照组无差异。肾脏冷诱导利尿是由于肾小球滤过率增加。在冷适应过程中，无论是在寒冷还是炎热环境下，肾脏的钠排泄均减少。钠排泄的减少似乎是由于肾脏中钠泵能力的增加。
