B. monnieri extract (BME) is an abundant source of bioactive compounds, including saponins and flavonoids known to produce vasodilation. However, it is unclear which components are the more effective vasodilators. The aim of this research was to investigate the vasorelaxant effects and mechanisms of action of saponins and flavonoids on rat isolated mesenteric arteries using the organ Cited by: 3. We investigated the effects of engineered nanoparticles on vasomotor responses of small intrapulmonary arteries using isometric tension measurements. Acute in vitro exposure to carbon nanoparticles (CNP) decreased, and in some case abolished, the vasomotor responses induced by several vasoactive agents, whereas acute exposure to titanium dioxide nanoparticles (TiO{sub 2}NP) .

  Vascular myography is an in vitro technique used to examine functional responses of isolated blood vessels. This classical pharmacological technique has been in use for over a century. The assay technique studies changes in isometric tone of large and small vessels, arteries and veins, and tissues from genetic or disease by: 1. Li Y, Brookes ZLS, Kaufman S.

We undertook this study to determine whether the rat mesenteric artery produces aldosterone and to investigate the effects of adrenalectomy, an angiotensin-converting enzyme inhibitor, Ang II, or potassium on aldosterone production in vascular tissue.

The Effects of Corticosteroids on the Reactivity of Rat Mesenteric Arterial Vessels. Author: Sarsam, J. Contractions of mesenteric artery strips and aortic strips from deoxycorticosterone–salt-treated rats in response to protein kinase C activators (phorbol esters) were greater than contractions in non-corticosteroid-treated (control) animals, suggesting that the corticosteroid target is quite distal in the vasoconstrictor signal transduction by: Changes in intravascular pressure or stretch are known to affect vascular reactivity.

However, the mechanisms that couple the changes in intravascular pressure or stretch to alterations in vascular reactivity are still not clear. In a recent review, Meininger and Davis (3) discussed possible by: 5. This thesis, written by Rohit Chawla, and entitled Vascular Reactivity of Isolated Rat Mesenteric Arterioles in the Presence and Absence of Ouabain, having been approved in respect to style and intellectual content, is referred to you for judgment.

We have read this thesis and recommend that it be approved. Date of Defense: J The effect of taurine on vascular reactivity was investigated in the mesenteric artery of Wistar Kyoto (WKY), and stroke-prone spontaneously hypertensive rats (SHRSP).

Administration of taurine significantly decreased blood pressure of SHRSP but not by: That is, direct effects of estrogen and testosterone on other tissues may have elicited the synthesis of factors that then directly modified gene expression in the mesenteric arteries.

We attempted to limit these potential secondary effects by using relatively brief sex steroid treatment duration. OBJECTIVE: This study sets out to investigate the effects of the female sex steroids, 17beta-estradiol and progesterone (separately and in combination) on vasoactive responses to calcitonin gene-related peptide (CGRP), acetylcholine, and 5-hydroxytryptamine (5-HT) in rat isolated mesenteric, caudal, and basilar by: The acute reduction of mesenteric blood flow in the rat caused by cigarette smoke and the chronic reduction of mucosal blood flow in the rectum of long-term smokers are most likely due to nicotine-mediated stimulation of sympathetic vasoconstrictor neurons, because nicotine does not constrict the isolated mesenteric vascular bed.

When rat mesenteric arteries are. The present study was designed to characterize the effects of LPC in the isolated perfused rat mesenteric arterial bed (MAB) and to investigate the underlying. Objective.—This study sets out to investigate the effects of the female sex steroids, 17β‐estradiol and progesterone (separately and in combination) on vasoactive responses to calcitonin gene‐related peptide (CGRP), acetylcholine, and 5‐hydroxytryptamine (5‐HT) in rat isolated mesenteric, caudal, and basilar by: CORTICOSTEROIDS INHIBIT PROSTAGLANDIN RELEASE FROM PERFUSED MESENTERIC BLOOD VESSELS OF RABBIT AND FROM PERFUSED LUNGS OF SENSITIZED GUINEA PIG Ryszard J.
