The effects of intravenous administration of propionyl-L-carnitine (PLC) were investigated in anesthetized dogs instrumented for the analysis of general hemodynamic and electrocardiographic data, peripheral blood flows, coronary blood flow and oxygen consumption, urine flow, and renal function. PLC was administered in bolus (20, 60, and 200 mg/kg) or by(More)
The exact relationship between depression and chronic headache remains unclear. Considerable clinical and pharmacological evidence suggests the existence of a common biological terrain. Many antidepressant drugs are effective in the treatment of migraine and chronic headache disorders. Ritanserin, a new very selective serotonin-2 (5-HT2) antagonist, has(More)
Choice reaction time with manual response (right and left hand) to alphabetic stimuli (capital letters A-E = positive stimulus, and R-F = negative stimulus) projected at 5 degrees in the nasal and in temporal hemisfield of the right eye (half of the subjects) and of the left eye (the remaining half) was studied in 12 normal subjects (6 males and 6 females).(More)
Treatment with propionyl-L-carnitine has been shown to increase the walking capacity of patients with peripheral vascular disease, but the mechanisms responsible for the effect are unknown. To study the effects of propionyl-L-carnitine on musculocutaneous vascular beds and the related mechanisms, a preparation of constant-pressure blood-perfused dog(More)
The activity of the venom of Bitis Gabonica on mesenteric and external iliac circulation was investigated in four anaesthetized dogs. Venom doses of 0.125, 0.25 and 0.50 mg/kg were injected intravenously with an interval of 30 minutes between two successive injections. Following the first and the second dose, a transient fall of the resistance was observed(More)
Withdrawal of the efferent vagal tone to the heart is an important factor of the increase of cardiac output (CO) and arterial blood pressure (ABP) in several conditions, such as exercise, emotion, postural changes. Vagal withdrawal enhances cardiovascular performance both by increasing heart rate (HR) and by other mechanisms, which were globally named(More)
