It has been shown morphometrically that a short-term cold exposure of rats (4 degrees C for 2 h) gives rise to an activation of the thyroid gland, paraventricular and ventromedial nuclei of the hypothalamus and to the enhanced neurohormonal release into the posterior pituitary vessels and into some areas of the median eminence. No significant changes were recorded in the supraoptic nucleus. The activity of the arcuate nucleus is likely to be reduced, being manifested in the diminution of nucleolar size. It might be thus assumed that function of the paraventricular and ventromedial nuclei correlates well with that of the thyroid gland. The arcuate and supraoptic nuclei apparently exert no activating effect on the thyroid gland.
形态学研究表明,对大鼠进行短期冷暴露(4摄氏度,持续2小时)会导致甲状腺、下丘脑室旁核和腹内侧核激活,并增强神经激素向后叶垂体血管和正中隆起某些区域的释放。视上核未记录到显著变化。弓状核的活性可能降低,表现为核仁大小减小。因此可以推测,室旁核和腹内侧核的功能与甲状腺功能密切相关。弓状核和视上核对甲状腺显然没有激活作用。
