Abstract

Microinjections of acetylcholine into the cat ventral reticular nucleus and nucleus of tractus solitarii in acute hypoxic hypoxia induce much lesser changes of efferent activity in renal and splenic nerves than in normoxia. Stimulation of the ventral reticular nucleus in hypoxia induces more obvious shifts of the efferent nerve activity than stimulation of the tractus solitarius nucleus. Bulbar reflex influences on cat's renal vascular bed are much more reduced in hypoxia than on the splenic one.

摘要

在急性低氧性缺氧状态下,向猫的腹侧网状核和孤束核微量注射乙酰胆碱所诱发的肾神经和脾神经传出活动变化,比在常氧状态下要小得多。缺氧时刺激腹侧网状核所诱发的传出神经活动变化,比刺激孤束核更为明显。延髓反射对猫肾血管床的影响在缺氧时比在脾血管床时减弱得更多。
