Duplex Doppler ultrasonography of the kidneys is a safe easy and non-invasive method to assess blood flow and arterial vascular resistance as a parameter for vasoconstriction.
Nicotine causes vasoconstriction as well as hypercoagulability, increasing the chance of blood clots occluding blood vessels.
The Interaction between Trolox and 4,4'-diisothiocyanatostilbene-2,2'-disulfonic Acid Stilbene on Hypoxic Pulmonary Vasoconstriction in the Isolated Rabbit Lung.
A symphatic spinal flow is triggered with a large release of adrenaline and noradrenaline due to hypothermia, which produces an extensive peripheral vasoconstriction with arteriovenous shunts that reduce the blood flow to these cold peripheral areas and, in turn, keeps the warm blood in the central compartment.
Administering vasopressin into the uterus will achieve a high concentration of the hormone, which stimulates both the oxytocin and vasopressin receptors, resulting in uterine contraction, vasoconstriction, and platelet activation.
Vasoconstriction and anti-inflammatory properties of the selective [alpha]-adrenergic receptor agonist brimonidine.
Authors stated previous research that "Prostaglandin E2 is involved in the classic signs of inflammation and possesses both pro-inflammatory and anti-inflammatory actions; thromboxane A2, formed by platelets, macrophages and polymorphonuclear leukocytes, can induce vasoconstriction and promotes aggregation of platelets as well as adhesiveness of polymorphonuclear neutrophils; leukotriene B4 (LTB4) can not only increase vascular permeability and enhance local blood flow by stimulating neutrophil secretion, but also stimulate other inflammatory substances.
The researchers noted as a limitation that the quality of the signal from which PVI is calculated is "critically based on peripheral perfusion, which may be significantly affected by factors such as extreme low cardiac output, drug-induced vasoconstriction, and hypothermia.
1) Ketamine causes vasoconstriction as a result of sympathetic stimulation; thus, long-term abuse leads to mucosal ischemia, atrophy and, ultimately, necrosis, followed by underlying cartilage or bone destruction.
This is secondary to renal vasoconstriction of the afferent arteriole.
laevifrons support the presence of two muscarinic receptors of high and low sensitivity to acetylcholine and a coupled mechanism between muscarinic receptors and vasoconstriction mediated by cyclooxygenase (Moraga and Urriola-Urriola, 2014).
pulmonary emboli), (2) elevated left atrial pressure (mitral stenosis), (3) thickening of pulmonary arterial and arteriolar walls (scleroderma), (4) derangement and destruction of alveolar walls with damage to pulmonary capillaries in proximity (interstitial lung disease), (5) left-to right shunting increasing blood flow in the pulmonary circulation (congenital cardiac anomalies), and (6) pulmonary vasoconstriction caused by hypoxemia, hypercapnia, and acidemia (COPD).
2] is used because it increases vasoconstriction by blocking of inward rectifying [K.
