The Photoactivated Relaxation of Smooth Muscle of Rabbit Aorta

Smooth muscle of strips of rabbit aorta, placed in a state of active tonic contraction by addition of a stimulating drug, relaxes during exposure to light. The relaxation is reversible. The extent of relaxation produced by a standard exposure depends on the preexposure level of active contraction but not on the nature of the stimulating drug used to produce contraction. With strips brought to a...

Preparation of functional smooth muscle cells from the rabbit aorta

A procedure for dissociating the rabbit aorta into single, functional smooth muscle cells is described. After removal of adventitia and intima, slices of media were incubated with purified collagenase, elastase, and soybean trypsin inhibitor in a Krebs-Ringer buffer modified with Hepes, amino acids, and a [Ca2+] of 0.2 mM. After enzymatic digestion and mechanical shear, the yield of dispersed c...

Calcium- and endothelial-mediated vascular smooth muscle relaxation in rabbit aorta.

The role of calcium in the relaxations evoked by methacholine and A23187 in intact rabbit aortic rings was investigated. Methacholine (10(-8) to 10(-6) M) and the calcium ionophore A23187 (10(-8) to 10(-6) M) produced dose-dependent relaxations of rings which had been contracted with the alpha-adrenergic agonist phenylephrine. The ability of a ring to relax in this manner was correlated with th...

Endothelium-Dependent Relaxation of Rabbit Aorta

Exposure of isolated arteries to oxidatively modified low density lipoprotein (LDL) has been reported to suppress endothelium-dependent relaxation (EDR). To determine whether lipid degradation products in oxidized LDL contribute to impaired relaxation, we have tested the responsiveness of isolated rabbit aortas to endothelium-dependent relaxants (acetylcholine, ATP, and calcium ionophore A23187...

A study of releasable Ca fractions in smooth muscle cells of the rabbit aorta

The distribution of Ca in the cellular compartment of smooth muscle cells of the rabbit aorta has been studied by analyzing the effect of norepinephrine, caffeine, and DNP on 45Ca exchange and on the pattern of tension development. These three substances increase the release of 45Ca from the tissue, but DNP acts more slowly than norepinephrine or caffeine. Also, the effect of norepinephrine and...
