In rats cold--adapted (1--3 degrees C) or warmth--adapted (26--28 degrees C) for 4--5 weeks, the body temperature, oxygen uptake, electric muscle activity were continuously recorded before and after intraventricular injection of noradrenaline (NA) at a total volume of 5--8 mcl. At the ambient temperature of 25 degrees C, extremely small doses (5--8 mcg) of NA raised the body temperature due to shivering. Injections of NA were more effective in the cold--adapted rats. Injections of NA at a low ambient temperature (10 degrees C) evoked greater thermoregulatory responses in the warmth-adapted rats.
将大鼠分别冷适应（1 - 3摄氏度）或热适应（26 - 28摄氏度）4 - 5周，在脑室内注射总量为5 - 8微升去甲肾上腺素（NA）前后，持续记录其体温、摄氧量和肌肉电活动。在25摄氏度的环境温度下，极少量（5 - 8微克）的NA会因寒战而使体温升高。NA注射对冷适应大鼠更有效。在低环境温度（10摄氏度）下注射NA，热适应大鼠会产生更大的体温调节反应。
