Sympathetic baroreceptor responses after chronic NG-nitro-L-arginine methyl ester treatment in conscious rats.
Blood pressure elevations after nitric oxide inhibition may result in part from increased sympathetic tone. In this study arterial baroreceptor reflex control of heart rate, renal sympathetic nerve activity (RSNA), and adrenal sympathetic nerve activity (ASNA) were compared in rats given normal tap water or a 3.7 nmol/L (10 mg%) solution of NG-nitro-L-arginine methyl ester (L-NAME) for 1 or 5 w...
متن کاملNG-nitro L-arginine methyl ester and other alkyl esters of arginine are muscarinic receptor antagonists.
Analogues of L-arginine with modifications at the terminal guanidino nitrogen and/or the carboxyl terminus of the molecule have been widely used for their ability to inhibit the production of nitric oxide and are thought to be competitive antagonists of nitric oxide synthase. The present studies were designed to test the possibility that these agents are also muscarinic receptor antagonists. Ac...
متن کاملTiming of administration of dexamethasone or the nitric oxide synthase inhibitor, nitro-L-arginine methyl ester,
1. The effects of the nitric oxide synthase (NOS) inhibitors, NG-nitro-L-arginine-methyl ester (L-NAME), nitroiminoethyl-L-ornithine and Smethylisothiourea on skeletal muscle survival following 2 h of tourniquet ischaemia and 24 h of reperfusion were compared with those of the antiinflammatory steroid, dexamethasone. 2. Administration of each of the NOS inhibitors or dexamethasone 30 min before...
متن کاملEffects of NG-nitro-L-arginine methyl ester on renal function and blood pressure.
The dose-dependent effects of intravenous infusions of nitric oxide (NO) synthesis inhibitor, NG-nitro-L-arginine methyl ester (L-NAME; 0.1, 1, 10, and 50 micrograms.kg-1.min-1), were studied in anesthetized rats to determine whether the inhibitory actions of L-NAME are manifested primarily in alterations of renal function or whether they are the consequences of the increase in systemic blood p...
متن کاملHypertensive response to chronic NG-nitro-L-arginine methyl ester (L-NAME) treatment is similar in immature and adult Wistar rats.
The aim of our study was to evaluate whether the blood pressure (BP) response to chronic inhibition of NO synthase (NOS) is exaggerated in young rats, which were reported to develop a more pronounced salt hypertension than the adult ones. The enhanced BP rise in immature rats subjected to excess salt intake might be due either to a generally increased reactivity in immature organisms to these s...
