were studied. Observations were made upon changes in heart rate, myocardial oxygen consumption, systolic vigor, and the electrocardiograms. Data are presented showing the effects of nitroglycerin and adrenergic agents when given separately and in combination. Results indicate that in dogs, nitroglycerin produces no antiadrenergic effects on the myocardium. The suggestion is made that the T wtav...

木崎 静子 ・安孫子 保 It has been reported that spleen strips contract with an addition of adrenaline (1 3), noradrenaline (3), acetylcholine (1-3), histamine (1-2) or 5-hydroxytryptamine (2) to the bath medium. The adrenaline-induced contraction of the spleen strips can be block ed by alpha-adrenergic blocking agents (1-4). According to Bickerton (4), isoproterenol, which stimulates beta-adrenergic rec...

With numerous safe and effective antihypertensive drugs now available, the clinician should no longer choose only diuretic agents or /3-adrenergic receptor blockers (/3-blockers) as initial therapy. Five classes of agents, including angiotensin converting enzyme inhibitors, /3-blockers, calcium entry blockers, peripheral a,-adrenergic receptor blockers, and thiazide diuretic agents, are all app...
