In rat subepicardial arteries, flow-induced dilation is endothelium-dependent and mediated by both NO and a prostanoid. (silverchair.com)
Therefore, treatment with complex saponin extracted from P. grandiflorum and G. uralensis mixture extract may selectively accelerate cerebral blood flow through basilar arterial dilation. (kjpr.kr)
Arterial rings2
The adrenoceptor subtype in mediating nicotine-induced vasodilation in isolated porcine basilar arterial rings denuded of endothelium was therefore examined pharmacologically and immunohistochemically. (lookformedical.com)
To this end, arterial rings with intact or damaged endothelium were used in an organ bath experiment and contracted by endothelin. (kjpr.kr)
Vasodilation4
We previously reported that nicotine-induced nitric oxide (NO)-mediated cerebral neurogenic vasodilation was dependent on intact sympathetic innervation. (lookformedical.com)
This study considered the hypothesis that the anesthetics may also attenuate flow-induced endothelium-dependent vasodilation. (silverchair.com)
Volatile anesthetics attenuate agonist-mediated endothelium-dependent vasodilation (EDD) of both conductance [3,4] and resistance arteries [5,6] in vitro and of pulmonary vessels in vivo. (silverchair.com)
MicroM1
Results from using an in vitro tissue bath technique indicated that propranolol and preferential beta(2)-adrenoceptor antagonists (ICI-118,551 and butoxamine), in a concentration-dependent manner, blocked the relaxation induced by nicotine (100 microM) without affecting the relaxation elicited by transmural nerve stimulation (TNS, 8 Hz).

Vitro2
QLY-related compounds berberine, dioscin and sophocarpine showed high binding affinities to SIRT1, stabilized this protein, and inhibited its deacetylation activity in vitro. (bvsalud.org)
We also identify that FSP1 can catalyze the production of H2O2 and the conversion of FAD to 6-hydroxy-FAD in the presence of oxygen and NAD(P)H in vitro, and 6-hydroxy-FAD directly inhibits ferroptosis in cells. (bvsalud.org)
Resistance2
We sought to determine the ionic mechanisms of isoproterenol-induced hyperpolarization in the rat mesenteric resistance artery, as well as the age-related changes in isoproterenol-induced hyperpolarization and their underlying mechanisms. (lookformedical.com)
We studied changes in pressure gradient across isolated coronary resistance arteries while keeping the intravascular pressure constant to remove any myogenic effects. (silverchair.com)
Cerebral2
It stimulates both the alpha- and beta- adrenergic systems, causes systemic VASOCONSTRICTION and gastrointestinal relaxation, stimulates the HEART, and dilates BRONCHI and cerebral vessels. (lookformedical.com)
Results of double-labeling studies indicated that beta(2)-adrenoceptor immunoreactivities and NADPH diaphorase reactivities were colocalized in the same nerve fibers in basilar and middle cerebral arteries. (lookformedical.com)
