Abstract

Ingestion in rats given limited daily access to water of 12 degrees , 24 degrees , and 37 degrees C is a positive function of water temperature, even though ingestion of warm water decreases blood osmotic concentration faster than cold water. The paradox suggests that temperature-dependent gastric factors and water-transport factors determine stomach distention cues of thirst satiation.

摘要

在每日饮水量受限的大鼠中，摄入12摄氏度、24摄氏度和37摄氏度的水时，饮水摄入量是水温的正函数，尽管摄入温水比冷水能更快降低血液渗透浓度。这一矛盾现象表明，温度依赖性胃因素和水运输因素决定了口渴饱腹感的胃扩张信号。
