An Intrinsic Adrenergic Vasodilator Mechanism in the Coronary Vascular Bed of the Dog.

• Considerable evidence indicates that an adrenergic vasoconstrictor mechanism exists in the coronary vascular bed. In the classification advanced by Ahlquist,' the sites mediating this response are termed alpha receptors. Whether or not an adrenergic dilator mechanism exists also in the coronary vessels remains controversial, since it is unclear whether the decrease of coronary resistance that...

Evaluation of vascular effects of aqueous Crocus sativus petals’ extract in the hypertensive rats

Background and Aim: Crocus sativus (C. sativus) petals attenuates smooth muscle tension and blood pressure in control animals. However the antihypertensive effect and its mechanisms haven’t been recognized. This study investigates the antihypertensive effects of C. sativus petals’ aqueous extract in hypertensive rats and also responses of the rat isolated perfused mesenteric bed. Materials and...

Effect of insulin on the performance and metabolism of the anoxic isolated perfused rat heart.

When the oxygen supply to the myocardium is compromised, glycolysis may provide the critical energy necessary for the heart's survival. We investigated whether insulin, through its effects on myocardial glycolysis, influences the performance and the metabolism of the perfused rat heart during anoxia. Hearts in a modified Langendorff apparatus were perfused for 30 minutes with anoxic media conta...

Effect of passive myocardium on the compliance of porcine coronary arteries.

The objective of this study was to determine the effect of passive myocardium on the coronary arteries under distension and compression. To simulate distension and compression, we placed a diastolic-arrested heart in a Lucite box, where both the intravascular pressure and external (box) pressure were varied independently and expressed as a pressure difference (DeltaP = intravascular pressure - ...
