1. The effects of graded intravenous infusions of sodium nitroprusside on resting blood pressure and heart rate and on the reflex changes in these variables evoked by a standardized Valsalva manoeuvre were studied in six normal subjects. The effects of nitroprusside on the above variables were also studied after pre-treatment with captopril, to allow assessment of the role of angiotensin II.. 2. Nitroprusside given in doses ranging from 7.5 to 150 μg/min elicited dose-related decreases in resting blood pressure and rise in heart rate and in plasma renin activity (PRA). After pretreatment with captopril, nitroprusside could not be given at doses above 60 μg/min without producing an unacceptable fall in blood pressure. The rise in heart rate in response to a given dose of nitroprusside was little altered after captopril.. 3. Blood pressure and heart rate were studied during the last 10 s of the Valsalva manoeuvre. Before captopril the normal response (maintenance of blood pressure with ...
TY - JOUR. T1 - Sodium nitroprusside exacerbates myocardial ischemia-reperfusion injury. AU - Cope, Jeffrey T.. AU - Banks, David. AU - Laubach, Victor E.. AU - Binns, Oliver A.R.. AU - King, R. Christopher. AU - Richardson, R. Mark. AU - Shockey, Kimberly S.. AU - Tribble, Curtis G.. AU - Kron, Irving L.. PY - 1997/12/1. Y1 - 1997/12/1. N2 - Background. The role of nitric oxide in myocardial ischemia-reperfusion is controversial. Although many studies claim that nitric oxide ameliorates reperfusion injury, others suggest that it exacerbates such injury, possibly through peroxynitrite production. These discordant results may be attributable to a dose-dependent phenomenon. Methods. Isolated rabbit hearts sustained sequential periods of blood perfusion (20 minutes), warm ischemia (30 minutes), and reperfusion (20 minutes). During reperfusion, four groups underwent intracoronary infusion of saline solution (n = 6), or the nitric oxide donor sodium nitroprusside (100 nm/min [SNP100, n = 6], 1 nmol ...
Efficient gene transfer by vectors that can be easily delivered to target organs is desirable in clinical gene therapy. We tested the hypothesis that intracoronary infusion of the nitric oxide donor nitroprusside would increase the efficiency of adenovirus vector-mediated gene transfer to the heart. Intracoronary delivery of an adenovirus encoding murine adenylyl cyclase type VI (Ad.AC(VI)) was performed in adult pigs with and without simultaneous intracoronary infusion of nitroprusside. Animals were killed 12-14 days after Ad.AC(VI) delivery and myocardial adenylyl cyclase activity was measured. Addition of nitroprusside during intracoronary infusion of Ad.AC(VI) was associated with a 4-fold increase in cAMP-generating capacity in the left ventricle. Transgene expression was confirmed by immunoblotting. Intracoronary nitroprusside produced mild dose-dependent changes in blood pressure and heart rate during infusion. Intracoronary nitroprusside infusion is a safe and effective means to increase ...

Recent studies have shown that nitric oxide (NO) may be involved in diverse plant developmental processes as an important signal molecule. However, the effects of NO on vegetative and reproductive growth of intact plants are not fully understood. In our study, the NO donor sodium nitroprusside (SNP) at 3,000, 6,000 and 9,000 μM was used to characterize the roles of NO in vegetative and reproductiv ...
1 The aim of this study was to examine whether sodium nitroprusside (SNP)-induced relaxation of rat fundus longitudinal smooth muscle involves ryanodine-sensitive Ca2+ release. 2 SNP (300 nM-30 microM) elicited concentration-dependent relaxation of precontracted (1 microM carbachol) rat fundus, an effect almost abolished by the selective guanylyl cyclase inhibitor, 1H-[1,2,4]oxadiazolo[4,3-a]quinoxaline-1-one (ODQ, 10 microM). 3 SNP-mediated relaxations were almost abolished by 10 microM ryanodine. 4 SNP-mediated relaxations were also reduced by either 1 microM apamin (a selective small conductance Ca(2+)-sensitive K+ channel, SKCa, inhibitor) or the selective L-type Ca2+ channel inhibitor, nicardipine (3 microM). 5 SNP-induced relaxations were insensitive to 1 mM tetraethylammonium chloride (an inhibitor of large-conductance Ca(2+)-sensitive K+ channels) and 1 microM glibenclamide (an ATP-sensitive K+ channel inhibitor). 6 These data suggest that SNP-mediated fundus relaxation occurs via a ...
Since the mechanism of salt impairing NO-induced vascular relaxation is not fully clear, this study was designed to investigate the role of potassium (K+) channels in the vasodilatory effects of NO donor in salt loaded rats. Isolated thoracic aortic rings of adult male albino rats fed 8% NaCl containing diet for six weeks were used for isometric tension recording using PowerLab tissue bath system. The recorded data revealed that high salt diet (HS) did not change the relaxation responses to sodium nitroprusside (SNP, an NO donor) in rats thoracic aortic rings. SNP-induced relaxation in salt loaded rats was significantly lower in rings contracted by high K+ than phenylephrine (PE, a selective α1-adrenergic receptor agonist). On the other hand, incubation of aortic rings from salt loaded rats with inward-rectifier K+ (KIR) channel blockers either individually or simultaneously with other K+ channel blockers significantly inhibited SNP-induced relaxation in PE-contracted rings; however incubation ...

In an open-label study, we compared the efficacy and safety of intravenous infusion of fenoldopam mesylate with that of sodium nitroprusside in patients with severe hypertension or in hypertensive crisis. Both antihypertensive medications were infused at a maximal dose increment of 0.2 microgram/kg/min (fenoldopam) and 1 microgram/kg/min (nitroprusside), with a maximal infusion rate of 1.5 micrograms/kg/min fenoldopam mesylate or 8 micrograms/kg/min sodium nitroprusside. Once the desired reduction in diastolic blood pressure was achieved (less than 110 mm Hg if initial diastolic blood pressure was 120-149 mm Hg, or by at least 40 mm Hg if initial diastolic blood pressure was 150-190 mm Hg), the maximal infusion rate used was maintained for at least 1 hour, and then, the infusion was slowed gradually over 2 hours. After the infusion treatment, patients remained in the hospital for 2 days of follow-up. Both antihypertensive agents successfully controlled the blood pressure in all the patients by ...

Pulmonary arterial hypertension (PAH) is a rare blood vessel disorder of the lung in which the pressure in the pulmonary artery (PA) rises above normal levels and may become life threatening. PAH is frequently misdiagnosed and has often progressed to late stage by the time it is accurately diagnosed. PAH has been historically chronic and incurable with a poor survival rate. However, new treatments are available which have significantly improved prognosis. Right-heart catheterization (RHC) is the most accurate and useful test for PAH, and the only test that directly measures the pressure inside the PA. It is performed in all patients at least once, to get a definitive diagnosis of PAH.. The most commonly used medication for this purpose is intravenous nitroprusside, however this medication in about 25-30% of patients is not well tolerated as it cause fast heart rates, which is not well tolerated by patients with pulmonary hypertension and/or heart failure. The CARVE study assesses the effect of ...

Nitric oxide (NO) as well as its donors has been shown to generate mutation and DNA damage in in vitro assays. The objective of this study was to identify that DNA single-strand breaks (SSBs) could be elicited by NO, not only in vitro but also in vivo. The alkaline single-cell gel electrophoresis (SCGE) was performed to examine the DNA damage in g12 cells and the cells isolated from the organs of mice exposed to sodium nitroprusside (SNP). A modified method, in which neither collagenase nor trypsin was necessary, was used to prepare the single-cell suspension isolated from organs of mice. Results showed that the exposure of g12 cells to 0.13-0.5 mu mol/ml SNP with S9 for 1 h induced a concentration-dependent increase in DNA SSBs in g12 cells. The significant increase in DNA migration and comet frequency has appeared in the cells isolated from the spleen, thymus, and peritoneal macrophages of mice after injecting i.p. SNP in the dosage range of 0.67-6.0 mg/kg b.wt for 1 h. However, no obvious ...

1. The contraction and relaxation responses to the polyoxyethylated vehicles currently used for the intravenous and oral administration of cyclosporin A in allograft recipients were studied in isolated rat aorta. The results were compared with those obtained with commercially available cyclosporin A for intravenous administration.. 2. None of these compounds affected resting tension, noradrenaline-induced contraction or endothelium-independent relaxation produced by sodium nitroprusside or bumetanide. However, they all reversed the relaxation induced by acetylcholine, carbamylcholine or adenosine 5′-triphosphate, by a factor of approximately 66%.. 3. This reversal of relaxation was unaffected by indomethacin and did not require the presence of cyclosporin A in the vehicles, and was completely abolished by l-arginine (3 × 10−-5 mol/l).. 4. It is concluded that vehicles used for commercial preparations of cyclosporin A interfere with the synthesis of endothelium-derived relaxing factor at an ...
Control of physiological states such as mean arterial pressure (MAP) has been successfully achieved using single drug by different control algorithms. Multi-drug delivery demonstrates a significantly challenging task as compared to control with a single-drug. Also the patients sensitivity to the drugs varies from patient to patient. Therefore, the implementation of adaptive controller is very essential to improve the patient care in order to reduce the workload of healthcare staff and costs. This paper presents the design and implementation of the model reference adaptive controller (MRAC) to regulate mean arterial pressure and cardiac output by administering vasoactive and inotropic drugs that are sodium nitroprusside (SNP) and dopamine (DPM) respectively. The proposed adaptive control model has been implemented, tested and verified to demonstrate its merits and capabilities as compared to the existing research work.. ...
In the reaction of [Fe(CN)5NO]3- with O2 (4:1 stoichiometry), the nitroprusside ion [Fe(CN)5NO]2- (NP) was quantitatively produced. The rate law was -1/4d[Fe(CN)5NO3-]/dt = k2[Fe(CN)5NO3-][O2], with k2 = (3.5 ± 0.2) × 105 M-1 s-1 at 25.0 C. The rate was insensitive to pH (range 9-11) and ionic strength (I = 0.1-1 M). Excess cyanide was used for minimizing the production of [Fe(CN)4NO]2-, which appeared to be much less reactive. Addition of O2 to the NO group is proposed to generate peroxynitrite bound to Fe(III), which reacts rapidly with [Fe(CN)5NO]3- to yield [Fe(CN)5NO2]3-. Reaction between the latter radical ions leads to the final product, NP. Comparison with the autoxidation rates for other NO complexes reveals that the rate constants decrease with an increase in ENO+/NO, the redox potentials of the bound NO+/NO couples. Six-coordination appears to be necessary for attaining reasonable electrophilic rates for the NO ligand, as with other heme and non-heme complexes ...

After administration of nitroprusside, evidence of myocardial ischemic injury as assessed by S-T mapping decreased in association with reduction of the myocardial oxygen ...
Migraine is a prevalent neurological disease that is characterized by unpredictable episodic attacks of intense head pain. The underlying pathology involves sensitization and activation of the trigeminal system. Although non-invasive vagus nerve stimulation (nVNS) is recommended for the treatment of migraine, the abortive mechanism of action is not well-understood. The goal of this study was to compare the ability of nVNS and sumatriptan to inhibit trigeminal activation in two animal models of episodic migraine and to investigate the receptor mechanism of action of nVNS. Nocifensive head withdrawal response was investigated in adult male Sprague Dawley rats using von Frey filaments. To induce trigeminal nociceptor sensitization, complete Freunds adjuvant was injected in the trapezius muscle and trigeminal neurons were activated by exposure to a pungent odor or injection of the nitric oxide donor sodium nitroprusside. Some animals received nVNS or sumatriptan as treatment. Some animals were injected
To compare the hemodynamic effects of a calcium-channel blocker with those of a conventional vasodilator in the awake preinstrumented dog, diltiazem and nitroprusside were administered in equihypotensive infusions before (decrease in mean aortic pressure by 10%; p less than .001, n = 6) and after (decrease in mean aortic pressure by 12%; p less than .001) chronic volume overload (CVO) produced by an infrarenal aortocaval fistula. Diltiazem had no effect on preload either before or after CVO. The maximal rate of change in left ventricular pressure (dP/dtmax) was unaffected by diltiazem before the aortocaval fistula (decrease in dP/dtmax by 6%; p = NS) but was significantly reduced by calcium-channel blockade after CVO (decrease in dP/dtmax by 22%; p less than .001). By contrast, at matched aortic pressures nitroprusside significantly reduced left ventricular end-diastolic dimension (LVEDD) and pressure (LVEDP) in the same animals before (decrease in LVEDD by 10%, p less than .05; decrease in ...

BACKGROUND: Some studies have demonstrated beneficial effects of L-arginine as a substrate for nitric oxide synthesis, and diclofenac as an inhibitor of cyclooxygenase (COX)-derived vasoconstrictive agents on vascular responses in humans during several pathological conditions. The aim of the present study was to investigate the acute effects of L-arginine and diclofenac on endothelium-dependent vasodilatation (EDV) and endothelium-independent vasodilatation (EIDV) in patients with chronic renal failure (CRF).. METHODS: Effects of L-arginine and diclofenac on EDV and EIDV were measured in 15 patients with CRF and in 15 healthy controls by means of forearm blood flow measurements with venous occlusion plethysmography during local intra-arterial infusions of methacholine (2 and 4 micro g/min evaluating EDV) and sodium nitroprusside (5 and 10 micro g/min evaluating EIDV).. RESULTS: L-Arginine infusion increased methacholine-induced vasodilatation both in patients with CRF and healthy controls. ...
The present study was designed to test the effect of acute endogenous estrogen deprivation on endothelium-dependent vasodilation in women in reproductive age. Therefore, in a group of female patients who underwent bilateral ovariectomy for uterine leiomyoma, we evaluated the forearm vascular response to acetylcholine and sodium nitroprusside, an endothelium-dependent and -independent vasodilator, respectively. As control subjects we selected healthy women well matched with the study group population for demographic and clinical parameters. Particular attention was paid to risk factors impairing endothelial function such as age, blood pressure, phase of the menstrual cycle, lipid and glucose profile, and smoking history. In the two study populations, the response to acetylcholine and sodium nitroprusside was similar, indicating preserved endothelium-dependent vasodilation in patients with leiomyoma. In contrast, after bilateral ovariectomy, the response to acetylcholine was found to be reduced ...

It is unknown whether and to what extent changes in various endothelial functions and adrenergic responsiveness are related to the development of microvascular complications in type 1 diabetes. Therefore, endothelium-dependent and endothelium-independent vasodilatation, endothelium-dependent hemostatic factors, and one and two adrenergic vasoconstrictor responses were determined in type 1 patients with and without microvascular complications. A total of 34 patients with type 1 diabetes were studied under euglycemic conditions on two occasions (11 without microangiopathy, 10 with proliferative and preproliferative retinopathy previously treated by laser coagulation, 13 with microalbuminuria, and 12 healthy volunteers also were studied). Forearm vascular responses to brachial artery infusions of N(G)-monomethyl-L-arginine (L-NMMA), sodium nitroprusside, acetylcholine (ACh), clonidine, and phenylephrine were determined. The ACh infusions were repeated during coinfusion of L-arginine. Furthermore, ...

In the present study, the role of reactive oxygen species and the contribution of antioxidant defence in the time course of changes in acetylcholine-stimulated endothelium-dependent and sodium nitroprusside-stimulated endothelium-independent relaxation were investigated in aortic rings isolated from 6-month streptozotocin-diabetic and age-matched control rats. Although there were no significant differences in the degree of the peak relaxations produced by a single administration of acetylcholine (1 μM) or sodium nitroprusside (0.01 μM) between control and diabetic rings, the endothelium-dependent and -independent relaxant responses were more transient and the time required to reach a peak relaxation after addition of acetylcholine was shorter in diabetic vessels. Pretreatment of diabetic vessels with superoxide dismutase (100 U/ml) normalized the recovery phases of endothelium-dependent and -independent relaxations, but had no effect on the peak responses to acetylcholine and sodium ...
