Enkephalin effects on blood pressure, heart rate, and baroreceptor reflex.
The cardiovascular effects of opioid peptides have been studied. Leucine-enkephalin (Leu-ENK) produced blood pressure (BP) increases following administration into the lateral brain ventricles (i.v.t.), into the cisterna magna (i.c.i.), and following intravenous (i.v.) administration. Heart rate (HR) increases were observed following all routes of administration (threshold for BP and HR effects ...
متن کاملEffects of [D-Ala]-Methionine-Enkephalin on Blood Pressure, Heart Rate, and Baroreceptor Reflex Sensitivity in Conscious Cats
Effects of intracerebroventricular (i.c.r.) injection of [D-Ala'1-methionine-enkephalinamide (DAME) on blood pressure (BP), heart rate, and baroreceptor reflex sensitirity were studied in conscious cats. DAME was administered at doses between 5 and 100 nmoles. Blood pressure and heart rate increased dose dependency. The sensitivity of the baroreceptor reflex was attenuated for IS to 60 minutes ...

Effects of intracerebroventricular (i.c.v) injection of [D-Ala2]-methionine-enkephalinamide (DAME) on blood pressure (BP), heart rate, and baroreceptor reflex sensitivity were studied in conscious cats. DAME was administered at doses between 5 and 100 nmoles. Blood pressure and heart rate increased dose dependently. The sensitivity of the baroreceptor reflex was attenuated for 15 to 60 minutes ...
متن کاملEvaluation of the baroreceptor-heart rate reflex by 24-hour intra-arterial blood pressure monitoring in humans.
The baroreceptor control of the sinus node was evaluated in 10 normotensive and 10 age-matched essential hypertensive subjects in whom ambulatory blood pressure was recorded intra-arterially for 24 hours and scanned by a computer to identify the sequences of three or more consecutive beats in which systolic blood pressure (SBP) and pulse interval (PI) progressively rose (+PI/+SBP) or fell (-PI/...
متن کاملEffects of work stress on ambulatory blood pressure, heart rate, and heart rate variability.
Work stress has repeatedly been associated with an increased risk for cardiovascular disease. This study tested whether this relationship could be explained by exaggerated cardiovascular reactivity to work or impaired recovery in leisure time. Vagal tone was assessed as a possible determinant of these work stress effects. Participants included 109 male white-collar workers (age, 47.2+/-5. 3) wh...
