nitroglycerin has been reported to reduce activated partial thromboplastin time (aptt) values in patients treated with concurrent heparin and nitroglycerin. however, studies have yielded conflicting results. to determine whether intravenous nitroglycerin alters the anticoagulant effect of heparin, we prospectively evaluated twenty patients admitted for coronary angioplasty by measuring their ap...

background: organic nitrates relax all kinds of smooth muscle , not only vascular smooth muscle , a fact that has allowed the use of these drugs to treat many different aliments. objective.-the purpuse of this study was to examine prosepectively benefical effects , if any, of sublingual nitroglycerin on the pain of renal colic. design.- prospective , randomised , double blind, placebo- contoled...

Introduction: Nitroglycerin is a fast-acting drug that rapidly dilates coronary arteries and thus increases blood flow to these vessels, and increases the blood flow through the lateral vessels to low blood areas. It also reduces both end diastolic pressure and volume of the left ventricular. However, the effect of nitroglycerin on the circulation hemodynamic is not known. Caro...

Objective(s): One of the most important problems of taking nitroglycerin is the nitrate tolerance phenomenon and endothelial dysfunction. Oxidative stress is a high-emphasized one of tolerance mechanisms. The possible effect of crocin, one of the anti-oxidant ingredients of saffron, on the nitrate tolerance model was investigated.Materials and Methods: I...

Abstract In this research, the effect of phthalate plasticizers in ethyl cellulose and ethyl cellulosesilica composite was investigated on the nitroglycerin migration from a double base propellant. In this manner, first different insulator and nanocomposite samples containing 10, 15 and 20 phr of diethyl phthalate, dibutyl phthalate and bis 2-ethylhexyl phthalate were prepared and then the dou...

Nitroglycerin dilates large (greater than or equal to 100 microns) but not small coronary arterial microvessels, and a putative metabolite of nitroglycerin, S-nitroso-L-cysteine, has been shown in vitro to dilate both large and small coronary microvessels. Based on this evidence, we tested the hypothesis that the lack of response of small coronary microvessels was due to an inability of small c...

Double base propellant consists of two main components, nitrocellulose and nitroglycerin and nitroglycerin migration from inter to surface of propellant, is the main problem of this type of propellants. In the effect of this undesirable phenomenon, due to the heterogeneity of nitroglycerin in the propellant matrix during Storage, in addition to decrease of safety, the ballistic properties will ...

The value of nitroglycerin in determining the potential reversibility of asynergy was examined in 35 patients with coronary heart disease. Ventriculograms performed at rest and after sublingual nitroglycerin were analyzed for (1) location of asynergy relative to distribution of the 3 major coronary arteries and (2) severity of asynergy. Of the 41 hypokinetic zones, 30 (73%) improved following n...
