Cold-acclimated rats with an increased resistance against intensive cold, differ from ordinary animals by increased beta 1- and decreased alpha 2-adrenoreactivity in ordinary conditions; their beta 1-adrenoreactive systems preserve sensitivity at intensive cold exposure (up to hypothermia below 25 degrees C), whereas the sensitivity of their alpha 2-adrenoreactive systems declines more rapidly (up to a moderate hypothermia--33-34 degrees C). The data obtained suggest the described shifts to be important for essential increase in general resistance against acute intensive cold exposure in rats.
对强烈寒冷具有增强抵抗力的冷适应大鼠，在正常情况下与普通动物不同，其β1 - 肾上腺素反应性增加而α2 - 肾上腺素反应性降低；它们的β1 - 肾上腺素反应系统在强烈寒冷暴露（直至体温低于25摄氏度的低温）时仍保持敏感性，而其α2 - 肾上腺素反应系统的敏感性下降得更快（直至中度低温——33 - 34摄氏度）。所获得的数据表明，上述变化对于大鼠总体抵抗急性强烈寒冷暴露的本质性增强很重要。
