Abstract:
Cytochrome P-450 has been suggested as a mediator of the signal between depleted platelet calcium stores and an increase in plasma membrane permeability to calcium which follows depletion of the stores. This hypothesis is based on the observations that inhibitors of cytochrome P-450, such as the imidazole antifungal agents, also inhibit influx of a calcium surrogate (manganese) into calcium-depleted platelets. We tested the effects of econazole and of a cytochrome P-450 inhibitor, carbon monoxide (CO), on thapsigargin (TG)-induced platelet 45Ca2+ influx. TG specifically depletes internal calci

Abstract:
In the present study, we have investigated the changes in calcium influx during the relaxing responses to adenosine and its analogues. Calcium-45 influx was measured in bovine coronary artery rings in the presence of prostaglandin F2 alpha (10(-5) M) and KCl (50 and 100 mM). Prostaglandin F2 alpha and KCl caused increases in calcium influx. Prostaglandin F2 alpha produced a further contraction when added to rings maximally contracted with KCl (100 mM or higher), suggesting two different mechanisms for prostaglandin F2 alpha- and KCl-induced contractions. Similarly, a greater calcium influx was
