1. The effects of the voltage dependent calcium channel blocking agent nifedipine, and of a calcium free bathing medium, on the responses of human blood vessels obtained postmortem to various agonists have been compared with those of the rat aorta. The human vessels studied were digital arteries, basilar arteries and metatarsal veins. 2. Responses to potassium chloride (5-80 mM), noradrenaline (10(-9)-10(-4) M), 5-hydroxytryptamine (10(-8)-10(-4) M) and U46619 (10(-11)-10(-6) M), in the…

This work has investigated the effect of L‐type Ca2+‐channel blockers and 5‐HT2 receptor antagonists on 5‐ HT‐ and K+‐induced contractions in rat aorta to explore the possibility of a relationship between blockade of L-typeCa2+ channels and 5-HT2 receptors antagonism.
LOE 908 : A specific blocker of nonselective cation channel
This review focuses on the recent development of Ca2+ entry channels in VSMCs activated by these agonists with special emphasis on their blockers, especially LOE 908 and its prototype SK&F 96365.
Ca2+ Entry Channels Involved in Contractions of Rat Aorta Induced by Endothelin-1, Noradrenaline, and Vasopressin
This study pharmacologically compared Ca2+ entry channels involved in contractions of rat thoracic aorta without endothelium induced by ET-1, noradrenaline (NA), or arginine-vasopressin (AVP) to show that the contraction of rat aortA involves different Ca2+, depending on agonists.


In vitro differences between human arteries and veins in their responses to hydralazine.

It is concluded that human arteries are much more sensitive to the effects of hydralazine than are human veins and that the mechanism of action ofhydralazine is probably due to inhibition of the release of tightly bound calcium ions.
A Human Arterial Preparation for Studying the Effects of Vasoactive Agents
It is concluded that human postmortem digital arteries can be studied effectively in vitro and should be useful for the evaluation of drugs that are thought to act at a peripberal vascular site.
Evidence for Greater Susceptibility of Isolated Dog Cerebral Arteries to Ca Antagonists than Peripheral Arteries
Dog cerebral arteries contracted with PGF2α, one of endogenous rasospastic substances, are more susceptible to agents which interfere with the influx of Ca++ across cell membranes than coronary and mesenteric arteries; these agents may thus be of value in the treatment and prophylaxis of cerebral vasospasm.
Relaxation of Large Coronary Artery by Verapamil, D600, and Nifedipine is Constrictor Selective: Comparison with Glyceryl Trinitrate
The effectiveness of Ca2-entry blockers in the treatment of coronary vasospasm may be dependent on the nature of the constrictor signal.

Nimodipine treatment in poor-grade patients with SAH results in an increase in the number of good outcomes and a reduction in the incidence of delayed neurological deterioration due to vasospasm.

Calcium requirement for activation of intact aortic smooth muscle.
It was concluded that high K(+)-induced depolarization activates the rabbit aorta by stimulating a net Ca uptake, and that the degree of activation is modified by c-AMP sensitive Ca accumulation by intracellular organelles.
