Gender and vascular reactivity

Lupus, 1999
Estrogen receptors are found on vascular endothelial and smooth muscle cells; their expression is influenced by exposure to the hormone. Estrogen receptors influence non-genomic events, which are rapid in onset and genomic events, which are longer acting responses.

Cadmium and vascular reactivity in the rat

Toxicology and Applied Pharmacology, 1975
Abstract Cadmium has been reported to induce hypertension accompanied by decreased vascular responsiveness to autonomic drugs in the rat and rabbit. Cadmium acetate administration to female Sprague-Dawley rats failed to elevate blood pressure, although cadmium-treated animals exhibited decreased blood pressure,responses to intravenously administered ...

Vascular reactivity and tissue oxygenation

Intensive Care Medicine, 1995
When blood carries less than the normal amount of oxygen (CaO2) or when blood flow (Q) decreases, oxygen delivery (DO2 = QCaO2) is gradually reduced. Compensatory adjustments occur in an attempt to satisfy the oxygen requirements of peripheral tissues.

Magnesium and Vascular Tone and Reactivity

Blood Vessels, 2008
It has been reported that the concentration of extracellular magnesium ions ([Mg++]_o) can affect blood flow, blood pressure and vascular reactivity in intact mammals. The present studies, using a variety of rat and rabbit blood vessels, were undertaken to shed further light on the relationship between [Mg++]<sub>o</sub ...

Metabolic syndrome and vascular reactivity

International Journal of Cardiology, 2008
Abstract The relationship between metabolic syndrome, white-coat hypertension and vascular reactivity to sympathetic stimulation is an intriguing point, particularly because there are several factors in the metabolic syndrome – hypertension, hyperglycaemia, altered lipid profile, increased body weight – able to influence the vessel wall response to ...

Control of vascular Reactivity in Pregnancy

American Journal of Kidney Diseases, 1987
Human pregnancy is characterized by a blunted pressor responsiveness to vasopressor substances. This was first reported by Dieckmann and Michel in 1937 in experiments in which they measured vascular reactivity to the pressor effects of a crude preparation of vasopressin.

Sex hormones and vascular reactivity

Herz, 1997
It is increasingly recognized that sex steroids have, among many other effects, the ability to cause vasodilation. The vasodilatory effects of estradiol have been the best documented and described. At low concentrations, estradiol has the ability to improve impaired endothelium dependent (nitric oxide mediated) relaxation in estrogen deficient subjects.

Vascular reactivity in diabetes mellitus

Current Diabetes Reports, 2002
Cardiovascular disease is responsible for 70% of the deaths in diabetes mellitus. Endothelial dysfunction occurs early in atherosclerosis and can now be assessed accurately and reproducibly by noninvasive means. Hyperglycemia, insulin resistance, microvascular complications, and coexistent conditions have been shown to impair endothelial function in ...

VASCULAR REACTIVITY STUDIES IN HYPERTENSION

Australian Journal of Experimental Biology and Medical Science, 1968
SummaryThe reactivity of the hand blood vessels to local intra‐arterial infusions of angiotensin and noradrenaline was studied in patients with primary, renovascular and malignant hypertension and correlated with plasma renin activity.In nineteen patients with primary hypertension and normal plasma renin activity the angiotensin and noradrenaline ...

Redox status and pulmonary vascular reactivity

Chest, 1985
Oxygen radicals are produced during oxidative metabolism in proportion to the tissue oxygen tension. The studies reported here have shown that oxygen radicals or the sulfhydryl oxidant, diamide, caused pulmonary vasodilatation in the isolated perfused rat lung.
