犬尿管筋電図に及ぼす自律神経剤の影響—第1報／副交感神経剤注射時の尿管筋電図

THE EFFECT OF SYMPATHETIC AND PARASYMPATHETIC DRUGS ON THE ELECT- ROMYOGRAMS OF THE DOG'S URETER. :I. ELECTROURETEROGRAPHIC STUDIES ON INTRAVENOUS ADMINISTRATION OF PARASYMPATHETIC DRUGS

　当教室白鳥等^1）の尿管筋電図学的研究の一環として，尿管に対する自律神経剤の影響を正確に観察する為に成犬86頭について副交感神経興奮剤及び麻痺剤静注時の尿管筋電図を観察し，2，3の興味ある知見を得たので報告する。

Under intravenous administration of the parasympathetic drugs, acetylcholine, pilo-carpine, neostigmine and parasympathetic drugs, buscopane*, finaline** and atropine, the action potentials of spontaneous peristal-sis were recorded on the exposed ureters of 68 adult dogs. As to the effect of these drugs on the ureteral action potential, the following were obtained.

1) After intravenous administration of parasympathomimetic drugs, accelerated ure-teral peristalsis, increased wave frequency and prolonged propagation velocity were ob-served.
