A case is reported of non-fatal acute cerebral haemorrhage in a 47-year-old female who was taking tranylcypromine and who drank 500 ml of normal beer. Since the tyramine contents of several beers, including low alcohol and alcohol free beer, are similar, it is recommended that patients taking
The decompensatory phase of hemorrhage (shock) is caused by a poorly defined phenomenon termed vascular hyporeactivity (VHR). VHR may reflect an acute in vivo imbalance in levels of contractile and relaxant stimuli favoring net vascular smooth muscle (VSM) relaxation. Alternatively, VHR may be
The present study sought to determine whether chemical destruction of peripheral catecholaminergic fibers with 6-hydroxydopamine (6OHDA) attenuates vasopressin (VP) and oxytocin (OT) secretion stimulated by hemorrhage, hypotension, and hyperosmolality. Rats received 6OHDA (100 mg/kg iv) or vehicle
In the pentobarbital sodium-anesthetized rat, hemorrhage of blood equivalent to 1% body weight (18.4% blood volume) increases plasma renin activity and plasma aldosterone concentration and also markedly elevates jejunal ion and water absorption. Infusion of angiotensin II (AII) also stimulates
This study analyzes the changes induced by subarachnoid hemorrhage (SAH) on the serotonin (5-hydroxytryptamine, 5-HT) uptake and release evoked in rabbit basilar arteries by tyramine. Rabbits were injected with 5 ml of autologous arterial blood into the cisterna magna to produce SAH. Tritium
In the forelimbs of anesthetized dogs, perfused at constant arterial inflow, we measured the pressure in a prenodal lymphatic vessel before and following arterial hemorrhage to a mean systemic arterial pressure of approximately 55 mmHg. We also made bolus intra-arterial injections of 1 microgram
A critical review of the literature on amine composition and relevant case reports provides rational guidelines for diet planning and counseling of patients on monoamine oxidase inhibitor (MAOI) drug regimens. Small amounts of normally harmless pressor amines in foods can lead to a hypertensive
1. Angiotonin refractoriness and hypotension follow upon injury to the central nervous system in dogs and cats. Refractoriness does not develop when the nervous system is quickly and expertly destroyed or the activity of the nervous system depressed by widespread injection into it of a local
Reports of hypertensive reactions from monoamine oxidase inhibitors (MAOI) began to proliferate in the early 1960s. Asatoor did extensive research and found that the combination of an MAOI and a food containing tyramine resulted in the hypertensive interaction ("the cheese reaction"). Because of the
1 Methods for the investigation of possible interactions with tricyclic antidepressant drugs are described. These methods have been applied to a new compound, Ciba 34276-Ba, which has been shown to have antidepressant activity. 2 In five normal volunteers tested before and during treatment with Ciba
Orthostatic hypotension and related neurologic symptoms are frequently encountered in clinical practice. The maintenance of appropriate blood pressure and heart rate responses upon assuming the upright posture are dependent upon: 1. intact mechanical (venous valves) mechanisms, 2. functioning
1. Pressor responses to tyramine, beta-phenylethylamine and angiotensin II were normal in urethane-anaesthetized rats 7 days after division of the common bile duct. The pressor response to noradrenaline was enhanced at the highest dose level used. 2. The hypotensive response to haemorrhage was
Intraportal injection of 6-hydroxydopamine (6-OHDA) was used to produce selective hepatic sympathectomy in the dog. Previously reported techniques for 6-OHDA induced hepatic sympathectomy in rats and cats were modified considerably using alpha and beta adrenergic blocking agents to prevent the
Cholestasis depresses cardiovascular function and responsiveness. In a previous study, the 3-day bile duct manipulated (BDM) rat was validated as the appropriate control for studying in vitro vascular neuroeffector mechanisms in cholestasis. The present study reports the findings on the effect of
