EULER Ulf (Ulf S. Euler, sort. in 1905) — the Swedish physiologist,
the member of the Swedish academy of Sciences, the Nobel Prize laureate (1970). Son of X. Euler-Heljpina.
Ended in 1929. Carolinian medical in in-t in Stockholm, was in same in-those the assistant to department of pharmacology (1930 — 1939), and since 1939 professor of physiology.
U. Euler is known for the researches of process of transfer of nervous impulses in a sympathetic nervous system. Its main works are devoted to physiology of adrenergic neurons. He established that a mediator of a sympathetic nervous system of mammals is noradrenaline, and investigated its distribution in nervous cells of l fabrics, and also feature of its exchange at various conditions of an organism. The subcellular particles containing noradrenaline were opened for them, mechanisms of capture, storage and release of noradrenaline are studied by these particles (see Catecholamines, Mediators). In 1936 U. Euler found prostaglandins (see) and investigated their functional role. Using a technique of registration of electric discharges of neurons, he established existence of osmoreceptors in supraoptic and paraventriku-lyarny kernels of a hypothalamus and neurons, and also receptors, sensitive to thermal stimulation, in front hypothalamic area (see Neyrogu moral regulation). The Nobel Prize is conferred together with B. Katts and J. Axelrod (see t. 10, additional materials) for researches of process of transfer of nervous impulses.
