BACKGROUND Nitrates are widely used to treat coronary artery disease, but their therapeutic value is compromised by the rapid development of tolerance. Recently, the renin-angiotensin system has been suggested to play an important role in the development of nitrate tolerance. METHODS AND RESULTS Sixty-four patients with coronary spastic angina were investigated to clarify the effect of angiot...
Organic nitrates are a group of very effective anti-ischemic drugs. They are used for the treatment of patients with stable angina, acute myocardial infarction, and chronic congestive heart failure. A major therapeutic limitation inherent to organic nitrates is the development of tolerance, which occurs during chronic treatment with these agents, and this phenomenon is largely based on inductio...
Statins have been reported to show preventive effect on nitrate tolerance in normal rats, but there are no reports on their effect in diabetic animals. In this study, diabetes was induced in male wistar rats by a single intraperitoneal injection of streptozotocin (45 mg/kg). Five groups of diabetic and five groups of normal rats were treated; groups 1 (of normal and diabetic rats) received ator...
In order to evaluate the effects of potassium nitrate nutrition on some low temperature tolerance indices in Citrus aurantium seedlings a factorial experiment was conducted based on a completely randomized design with four replications at the Institute of Citrus Research in Ramsar. Treatments were potassium nitrate nutrition at four levels (0, 2.5, 5, and 10 mM) and temperature at four levels (...
Although the short-term vasodilatory properties of organic nitrates are potent and well known, a number of vascular and extravascular changes have been shown to compromise their hemodynamic effects on long-term administration. Among these changes, systemic phenomena such as neurohormonal activation and intravascular volume expansion1 as well as specific vascular changes such as increased vascul...
