The investigations were carried out on 192 Wistar newborn rats of either sex, chronically exposed to cold or heat. 32P-incorporation into cerebral phospholipids, phosphoproteins and nucleic acids (RNA and DNA) as well as 32P-uptake by hypothalamus, pituitary and adrenals were studied. The results showed that both chronic exposure to cold and heat enhance 3-P-incorporation into cerebral phospholipids, phosphoproteins and nucleic acids, the exposure to cold inducing nevertheless more important modifications. 32P-uptake by hypothalamo-pituitary-adrenal axis is also stimulated, this stimulation being higher in 14-day-old rats exposed to cold. The authors discuss the importance of the nature of stress, of the animal age and its level of CNS maturation in the appearance of all these modifications.
对192只新生Wistar大鼠（雌雄不限）进行了研究，这些大鼠长期暴露于寒冷或炎热环境中。研究了32P掺入脑磷脂、磷蛋白和核酸（RNA和DNA）的情况，以及下丘脑、垂体和肾上腺对32P的摄取情况。结果表明，长期暴露于寒冷和炎热环境均会增强32P掺入脑磷脂、磷蛋白和核酸的过程，不过寒冷诱导的变化更为显著。下丘脑 - 垂体 - 肾上腺轴对32P的摄取也受到刺激，在暴露于寒冷环境的14日龄大鼠中这种刺激作用更强。作者讨论了应激性质、动物年龄及其中枢神经系统成熟水平在所有这些变化出现过程中的重要性。
