Abstract

Availability of water at temperatures higher than ambient (15, 25, 35 degrees C) failed both to affect the ratio of water to food intake during exposure to cold air (5 degrees C) and to influence the thermogenic (postcold exposure) drinking response of rats which characteristically occurs immediately after removal from cold air. Thus, availability of warm water during exposure to cold appeared to have no influence on cold-induced dehydration in rats. A specially constructed drinking apparatus was used in this study. It was designed to maintain water at temperatures greater than ambient during exposure to cold. Details for construction of the apparatus are provided.

摘要

在高于环境温度（15、25、35摄氏度）时提供水，既不会影响大鼠在暴露于冷空气（5摄氏度）期间水与食物摄入量的比例，也不会影响大鼠在从冷空气中移出后立即出现的典型产热（冷暴露后）饮水反应。因此，在冷暴露期间提供温水似乎对大鼠的冷诱导脱水没有影响。本研究使用了一种特制的饮水装置。其设计目的是在冷暴露期间将水温维持在高于环境温度的水平。文中提供了该装置的构造细节。
