Interactions between vasoconstrictors and vasodilators in regulating hemodynamics of distinct vascular beds.
We examined whether interactions between angiotensin II (Ang II), endothelin (ET), nitric oxide (NO), and prostaglandins (PGs) differentially regulate perfusion to distinct vascular beds. For this, we blocked either angiotensin AT1 or ET receptors or both and then sequentially inhibited NO and PG synthesis in anesthetized dogs. Blocking Ang II or ET had similar effects on systemic hemodynamics:...
متن کاملANTINOCICEPTIVE INTERACTION BETWEEN ADENOSINE AND CARBAMAZEPINE IN MICE
There are several reports that adenosine and carbamazepine have pharmacodynamic interaction. I n this study the antinociceptive interaction o f these two agents was evaluated in mice by the hot plate test. Agents were injected intraperitoneally. 0.2 and 0.4 mg/kg doses of R-phenylisopropyladenosine (R-PIA) substantially showed antinociceptive effects. Carbamazepine had antinociceptive acti...
متن کاملInteraction between nitric oxide and endogenous vasoconstrictors in control of renal blood flow.
The level of renal blood flow (RBF) is controlled by opposing vasoconstrictor and vasodilator influences. In a recent investigation in normotensive dogs, we found that combined blockade of endothelin type A (ET(A)) receptors and angiotensin II formation induces marked increases in RBF that were much larger than the effects of blocking either system alone. The aim of the present study was to det...

HASRIMOTO, K. and KOKUBUN, H. Interaction between Adenosine Compounds and Norepinephrine in Dog Renal Circulation. Tohoku J. exp. Med., 1972, 107 (4), 373-380 -Drugs were administered to anesthetized dogs directly into the left renal artery perfused with animal's own blood at a constant pressure. A single injection of adenosine caused prompt renal vasoconstriction, while an infusion of adenosin...
متن کاملInteraction between intruders in vibrated granular beds.
Two neutrally buoyant intruder particles in a granular bed fluidized by vertical, sinusoidal vibration are known to interact with each other over a range of about five intruder diameters. Using molecular dynamics simulations, we investigate in detail the spatial and temporal nature of this interaction. We show that the force of attraction between intruders can be calculated from the local densi...
