Abstract

The role of the adrenal glands, in morphine-induced hyperthermia was studied in normal, chemically-sympathectomized, adrenalectomized, adrenal-demedullated or splanchnicotomized rats. 2. In restrained female rats, 5 mg/kg morphine produced hyperthermia whereas 20 mg/kg and 40 mg/kg produced hyperthermia. 3. After adrenalectomy, 5 mg/kg morphine did not produce hyperthermia. 4. After adrenal-demedullation or adrenal-denervation (splanchnicotomy), 5 mg/kg morphine did not produce hyperthermia. 5. The results suggest that, in the rat, the adrenal medulla plays an important role in morphine-induced hyperthermia, and that morphine acts centrally to stimulate the medulla.

摘要

在正常、化学性交感神经切除、肾上腺切除、肾上腺髓质剥除或内脏神经切断的大鼠中,研究了肾上腺在吗啡诱导的体温过高中的作用。2. 在受限制的雌性大鼠中,5毫克/千克吗啡可导致体温过高,而20毫克/千克和40毫克/千克也会导致体温过高。3. 肾上腺切除后,5毫克/千克吗啡不会导致体温过高。4. 肾上腺髓质剥除或肾上腺去神经支配(内脏神经切断)后,5毫克/千克吗啡不会导致体温过高。5. 结果表明,在大鼠中,肾上腺髓质在吗啡诱导的体温过高中起重要作用,且吗啡通过作用于中枢来刺激髓质。
