During heat stress, most mammals regulate body temperature by evaporating body water. Dehydrated mammals reduce their evaporative water losses and allow body temperature to rise. The physiological mechanism underlying this inhibition of evaporative cooling in dehydration have remained unclear. We now report that the rate of evaporation in dehydrated, heat-stressed cats is controlled by intracranial osmoreceptors and suggest that these receptors are part of a common central neural osmoreceptive mechanism regulating evaporative heat loss, renal water loss and thirst.
在热应激期间，大多数哺乳动物通过蒸发体内水分来调节体温。脱水的哺乳动物会减少其蒸发失水量，并使体温升高。脱水时这种蒸发散热抑制作用的生理机制仍不清楚。我们现在报告，脱水且处于热应激状态的猫的蒸发速率受颅内渗透压感受器控制，并表明这些感受器是调节蒸发散热、肾失水量和口渴的共同中枢神经渗透压感受机制的一部分。
