Investigation of acute effects of aflatoxin on rat proximal and distal colon spontaneous contractions
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Aflatoxins are one of the most potent toxic, mutagenic, teratogenic, cancerogenic, and immunosuppresive substances that naturally Occurring contaminants of food. There are some studies in various animal species that have ...
Effects of formoterol and BRL 37344 on human umbilical arteries in vitro in normotensive and pre-eclamptic pregnancy
(ELSEVIER SCIENCE INC, 2007)
Alterations in vascular responses to beta-adrenoceptor agonists in normotensive pregnancy and pre-eclampsia are not fully understood. Thus, we studied changes in vasodilator responses to beta(2)-adrenoceptor agonist ...
Rho-kinase inhibitors Y-27632 and fasudil prevent agonist-induced vasospasm in human radial artery
(CANADIAN SCIENCE PUBLISHING, NRC RESEARCH PRESS, 2009)
Radial artery (RA) vasospasm remains a potential cause of early graft failure after coronary artery bypass graft surgery, despite pretreatment with alpha-adrenergic or calcium channel blockers. Our aim was to investigate ...
Nifedipine Enhances the Relaxant Effects of Cyclo-Oxygenase Inhibitors on the Bovine Ciliary Muscle
(MARY ANN LIEBERT, INC, 2008)
Background/Aims: The inhibition of cyclo-oxygenase (COX) enzymes and the blockade of Ca2+ channels play an important role in the regulation of smooth muscle relaxation. This study was designed to investigate the relaxant ...
Changes in spontaneous contractions of rat ileum by aflatoxin in vitro
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Aflatoxins are a group of mycotoxins produced by toxigenic strains of Aspergillus flavus, Aspergillus parasiticus and Aspergillus nomius as secondary metabolites. Most of the studies on the aflatoxins have focused mainly ...
Mechanism of relaxation induced by nicotine in normal and ovalbumin-sensitized guinea-pig trachea
(ELSEVIER SCIENCE BV, 2007)
Nicotine is an irritant molecule in the cigarette that contributes airway hyper-reactivity. The aim of this study was to investigate the mechanism of these effects and effects of nicotine on the isolated trachea preparations ...
Investigation of the relaxant effects of pancuronium, rocuronium, vecuronium and mivacurium on rat thoracic aorta
(LIPPINCOTT WILLIAMS & WILKINS, 2009)
Background and objective Pancuronium, vecuronium, mivacurium and rocuronium are nondepolarizing neuromuscular blocking agents, which are competitive antagonists against acetylcholine at nicotinic receptors, and considered ...
