[Changes in sympathetic activity in the renal and splenic nerves upon stimulation of bulbar nuclei during hypoxic hypoxia].
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.
