Abstract

Combined adaptation of rats to heat and cold increasing mechanisms of thermogenesis enhances resistance to both factors and heat dissipation. Adaptive changes in thermogenesis are mainly a result of activation of adrenergic mechanisms, while the separate cold adaptation is accompanied by hyperfunction of thyroid glands. Mechanisms of heat dissipation in rats of the "combined" group increase even more than those of "heat" group.

摘要

大鼠对热和冷的联合适应增加产热机制,增强了对这两种因素的抵抗力以及散热能力。产热方面的适应性变化主要是肾上腺素能机制激活的结果,而单独的冷适应则伴有甲状腺功能亢进。“联合”组大鼠的散热机制比“热”组增加得更多。
