NG-Nitroarginine Methyl Ester
Nitric Oxide Synthase
A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.
Tosylarginine Methyl Ester
Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.

Nitric Oxide Donors
A diverse group of agents, with unique chemical structures and biochemical requirements, which generate NITRIC OXIDE. These compounds have been used in the treatment of cardiovascular diseases and the management of acute myocardial infarction, acute and chronic congestive heart failure, and surgical control of blood pressure. (Adv Pharmacol 1995;34:361-81)
A 30-kDa COMPLEMENT C1Q-related protein, the most abundant gene product secreted by FAT CELLS of the white ADIPOSE TISSUE. Adiponectin modulates several physiological processes, such as metabolism of GLUCOSE and FATTY ACIDS, and immune responses. Decreased plasma adiponectin levels are associated with INSULIN RESISTANCE; TYPE 2 DIABETES MELLITUS; OBESITY; and ATHEROSCLEROSIS.
Cell surface receptors for ADIPONECTIN, an antidiabetic hormone secreted by ADIPOCYTES. Adiponectin receptors are membrane proteins with multiple cytoplasmic and extracellular regions. They are about 43 kDa and encoded by at least two genes with different affinities for globular and full-length adiponectin.
Highly reactive compounds produced when oxygen is reduced by a single electron. In biological systems, they may be generated during the normal catalytic function of a number of enzymes and during the oxidation of hemoglobin to METHEMOGLOBIN. In living organisms, SUPEROXIDE DISMUTASE protects the cell from the deleterious effects of superoxides.
Highly specialized EPITHELIAL CELLS that line the HEART; BLOOD VESSELS; and lymph vessels, forming the ENDOTHELIUM. They are polygonal in shape and joined together by TIGHT JUNCTIONS. The tight junctions allow for variable permeability to specific macromolecules that are transported across the endothelial layer.
A superfamily of small proteins which are involved in the MEMBRANE FUSION events, intracellular protein trafficking and secretory processes. They share a homologous SNARE motif. The SNARE proteins are divided into subfamilies: QA-SNARES; QB-SNARES; QC-SNARES; and R-SNARES. The formation of a SNARE complex (composed of one each of the four different types SNARE domains (Qa, Qb, Qc, and R)) mediates MEMBRANE FUSION. Following membrane fusion SNARE complexes are dissociated by the NSFs (N-ETHYLMALEIMIDE-SENSITIVE FACTORS), in conjunction with SOLUBLE NSF ATTACHMENT PROTEIN, i.e., SNAPs (no relation to SNAP 25.)
Soluble N-Ethylmaleimide-Sensitive Factor Attachment Proteins
SNARE binding proteins that facilitate the ATP hydrolysis-driven dissociation of the SNARE complex. They are required for the binding of N-ETHYLMALEIMIDE-SENSITIVE PROTEIN (NSF) to the SNARE complex which also stimulates the ATPASE activity of NSF. They are unrelated structurally to SNAP-25 PROTEIN.
Vesicular Transport Proteins
A broad category of proteins involved in the formation, transport and dissolution of TRANSPORT VESICLES. They play a role in the intracellular transport of molecules contained within membrane vesicles. Vesicular transport proteins are distinguished from MEMBRANE TRANSPORT PROTEINS, which move molecules across membranes, by the mode in which the molecules are transported.

Relaxin is a potent renal vasodilator in conscious rats. (1/3789)The kidneys and other nonreproductive organs vasodilate during early gestation; however, the "pregnancy hormones" responsible for the profound vasodilation of the renal circulation during pregnancy are unknown. We hypothesized that the ovarian hormone relaxin (RLX) contributes. Therefore, we tested whether the administration of RLX elicits renal vasodilation and hyperfiltration in conscious adult, intact female rats. After several days of treatment with either purified porcine RLX or recombinant human RLX 2 (rhRLX), effective renal plasma flow (ERPF) and glomerular filtration rate (GFR) increased by 20%-40%. Comparable renal vasodilation and hyperfiltration was also observed in ovariectomized rats, suggesting that estrogen and progesterone are unnecessary for the renal response to rhRLX. The nitric oxide synthase inhibitor Nomega-nitro-L-arginine methyl ester completely abrogated the increase in ERPF and GFR elicited by chronic administration of purified porcine RLX. In contrast, the renal vasoconstrictory response to angiotensin II was attenuated by the RLX treatment. Short-term infusion of purified porcine RLX to conscious rats over several hours failed to increase ERPF and GFR. Plasma osmolality was consistently reduced by the chronic administration of both RLX preparations. In conclusion, the renal and osmoregulatory effects of chronic RLX administration to conscious rats resemble the physiological changes of pregnancy in several respects: (a) marked increases in ERPF and GFR with a mediatory role for nitric oxide; (b) attenuation of the renal circulatory response to angiotensin II; and (c) reduction in plasma osmolality.

Effects of chronic nitric oxide activation or inhibition on early hepatic fibrosis in rats with bile duct ligation. (2/3789)Hepatic fibrosis or increased liver collagen contents drive functional abnormalities that, when extensive, may be life threatening. The purpose of this study was to assess the effects of the chronic stimulation or inhibition of nitric oxide synthesis in rats with hepatic fibrosis induced by permanent common bile duct ligation (3 weeks) and the role of expression of the different nitric oxide synthase isoforms. Bile duct ligation led to an important accumulation of collagen in the hepatic parenchyma, as shown both histologically and by the hydroxyproline contents of livers. Bilirubin and serum enzyme activities (measured as markers of cholestasis) increased several-fold after bile duct ligation. The area of fibrotic tissue, liver hydroxyproline content and serum markers of cholestasis were clearly related in obstructed rats. The absence of modifications in haemodynamic parameters excludes circulatory changes from being responsible for the development of liver alterations. In animals treated with NG-nitro-L-arginine methyl ester (L-NAME) the area of fibrosis was similar to that of untreated animals, the signs of cholestasis and cellular injury being more evident. In rats treated with L-arginine the area of fibrosis was almost three times larger than that found in bile duct ligated rats and in L-NAME-treated bile duct ligated rats, although the observed biochemical changes were similar to those seen in rats treated with L-NAME. Our results with inducible nitric oxide synthase, obtained by Western blots and immunohistochemistry, indicate a greater expression of the inducible enzyme in bile duct ligated and L-arginine-treated animals and a lower expression in the L-NAME and control groups. Constitutive nitric oxide synthase expression, obtained by Western blots, was very similar in all groups, except for the L-arginine-treated rats in which it was lower. These results suggest that nitric oxide production may be a key factor in the development of fibrosis in bile duct ligated rats. They also support the hypothesis of a dual role for nitric oxide; one beneficial, mediated by its circulatory effects, and the second negative, through its local toxic effects. (+info)
Impairment of neocortical long-term potentiation in mice deficient of endothelial nitric oxide synthase. (3/3789)The role of the possible retrograde messenger nitric oxide (NO) in the induction of long-term potentiation (LTP) was studied in supragranular layers of somatosensory cortical slices obtained from adult mice. High-frequency stimulation produced a slowly rising, long-lasting (50 min) and significant (P < 0.001) increase in the extracellular synaptic response by 23%. The induction of LTP was independent from activation of N-methyl-D-aspartate (NMDA) receptors, but prevented by bath application of NG-nitro-L-arginine methyl ester (L-NAME), indicating that one or several of the different NO synthases (NOS) produced NO within the postsynaptic neuron. No LTP could be induced in knockout mice lacking the endothelial NOS (eNOS) isoform. These data suggest that eNOS is involved in an NMDA receptor-independent form of LTP in the rodent cerebral cortex. (+info)
L-arginine stimulation of glucose-induced insulin secretion through membrane depolarization and independent of nitric oxide. (4/3789)The mechanism of L-arginine stimulation of glucose-induced insulin secretion from mouse pancreatic islets was studied. At 16.7 mmol/l glucose, L-arginine (10 mmol/l) potentiated both phases 1 and 2 of glucose-induced insulin secretion. This potentiation of glucose-induced insulin secretion was mimicked by the membrane depolarizing agents tetraethylammonium (TEA, 20 mmol/l) and K+ (60 mmol/l), which at 16.7 mmol/l glucose obliterated L-arginine (10 mmol/l) modulation of insulin secretion. Thus L-arginine may potentiate glucose-induced insulin secretion by stimulation of membrane depolarization. At 3.3 mmol/l glucose, L-arginine (10 mmol/l) failed to stimulate insulin secretion. In accordance with membrane depolarization by the electrogenic transport of L-arginine, however, L-arginine (10 mmol/l) stimulation of insulin secretion was enabled by the K+ channel inhibitor TEA (20 mmol/l), which potentiates membrane depolarization by L-arginine. Furthermore, L-arginine (10 mmol/l) stimulation of insulin secretion was permitted by forskolin (10 micromol/l) or tetradecanoylphorbol 13-acetate (0.16 micromol/l), which, by activation of protein kinases A and C respectively sensitize the exocytotic machinery to L-arginine-induced Ca2+ influx. Thus glucose may sensitize L-arginine stimulation of insulin secretion by potentiation of membrane depolarization and by activation of protein kinase A or protein kinase C. Finally, L-arginine stimulation of glucose-induced insulin secretion was mimicked by NG-nitro-L-arginine methyl ester (10 mmol/l), which stimulates membrane depolarization but inhibits nitric oxide synthase, suggesting that L-arginine-derived nitric oxide neither inhibits nor stimulates insulin secretion. In conclusion, it is suggested that L-arginine potentiation of glucose-induced insulin secretion occurs independently of nitric oxide, but is mediated by membrane depolarization, which stimulates insulin secretion through protein kinase A- and C-sensitive mechanisms.

Influence of nitric oxide modulators on cholinergically stimulated hormone release from mouse islets. (5/3789)1. We have investigated, with a combined in vitro and in vivo approach, the influence on insulin and glucagon release stimulated by the cholinergic, muscarinic agonist carbachol of different NO modulators, i.e. the nitric oxide synthase (NOS) inhibitors NG-nitro-L-arginine methyl ester (L-NAME), NG-monomethyl-L-arginine (L-NMMA) and 7-nitroindazole as well as the intracellular NO donor hydroxylamine. 2. At basal glucose (7 mM) carbachol dose-dependently stimulated insulin release from isolated islets with a half-maximal response at approximately 1 microM of the agonist. In the presence of 5 mM L-NAME (a concentration that did not influence basal insulin release) the insulin response was markedly increased along the whole dose-response curve and the threshold for carbachol stimulation was significantly lowered. 3. Carbachol-stimulated islets displayed an increased insulin release and a suppressed glucagon release in the presence of L-NAME, L-NMMA or 7-nitroindazole. Significant suppression of glucagon release (except for L-NAME) was achieved at lower concentrations (approximately 0.1-0.5 mM) of the NOS inhibitors than the potentiation of insulin release (1.0-5.0 mM). The intracellular NO donor hydroxylamine dose-dependently inhibited carbachol-induced insulin release but stimulated glucagon release only at a low concentration (3 microM). 4. In islets depolarized with 30 mM K+ in the presence of the KATP channel opener diazoxide, NOS inhibition by 5 mM L-NAME still markedly potentiated carbachol-induced insulin release (although less so than in normal islets) and suppressed glucagon release. 5. In vivo pretreatment of mice with L-NAME was followed by a markedly increased insulin release and a reduced glucagon release in response to an i.v. injection of carbachol. 6. The data suggest that NO is a negative modulator of insulin release but a positive modulator of glucagon release induced by cholinergic muscarinic stimulation. These effects were also evident in K+ depolarized islets and thus NO might exert a major influence on islet hormone secretion independently of membrane depolarization events. (+info)
Nitric oxide limits the eicosanoid-dependent bronchoconstriction and hypotension induced by endothelin-1 in the guinea-pig. (6/3789)1. This study attempts to investigate if endogenous nitric oxide (NO) can modulate the eicosanoid-releasing properties of intravenously administered endothelin-1 (ET-1) in the pulmonary and circulatory systems in the guinea-pig. 2. The nitric oxide synthase blocker N(omega)-nitro-L-arginine methyl ester (L-NAME; 300 microM; 30 min infusion) potentiated, in an L-arginine sensitive fashion, the release of thromboxane A2 (TxA2) stimulated by ET-1, the selective ET(B) receptor agonist IRL 1620 (Suc-[Glu9,Ala11,15]-ET-1(8-21)) or bradykinin (BK) (5, 50 and 50 nM, respectively, 3 min infusion) in guinea-pig isolated and perfused lungs. 3. In anaesthetized and ventilated guinea-pigs intravenous injection of ET-1 (0.1-1.0 nmol kg(-1)), IRL 1620 (0.2-1.6 nmol kg(-1)), BK (1.0-10.0 nmol kg(-1)) or U 46619 (0.2-5.7 nmol kg(-1)) each induced dose-dependent increases in pulmonary insufflation pressure (PIP). Pretreatment with L-NAME (5 mg kg(-1)) did not change basal PIP, but increased, in L-arginine sensitive manner, the magnitude of the PIP increases (in both amplitude and duration) triggered by each of the peptides (at 0.25, 0.4 and 1.0 nmol kg(-1), respectively), without modifying bronchoconstriction caused by U 46619 (0.57 nmol kg(-1)). 4. The increases in PIP induced by ET-1, IRL 1620 (0.25 and 0.4 nmol kg(-1), respectively) or U 46619 (0.57 nmol kg(-1)) were accompanied by rapid and transient increases of mean arterial blood pressure (MAP). Pretreatment with L-NAME (5 mg kg(-1); i.v. raised basal MAP persistently and, under this condition, subsequent administration of ET-1 or IRL 1620, but not of U-46619, induced hypotensive responses which were prevented by pretreatment with the cyclo-oxygenase inhibitor indomethacin. 5. Thus, endogenous NO appears to modulate ET-1-induced bronchoconstriction and pressor effects in the guinea-pig by limiting the peptide's ability to induce, possibly via ET(B) receptors, the release of TxA2 in the lungs and of vasodilatory prostanoids in the systemic circulation. Furthermore, it would seem that these eicosanoid-dependent actions of ET-1 in the pulmonary system and on systemic arterial resistance in this species are physiologically dissociated. (+info)
Role of iNOS in the vasodilator responses induced by L-arginine in the middle cerebral artery from normotensive and hypertensive rats. (7/3789)1. The substrate of nitric oxide synthase (NOS), L-arginine (L-Arg, 0.01 microM - 1 mM), induced endothelium-independent relaxations in segments of middle cerebral arteries (MCAs) from normotensive Wistar-Kyoto (WKY) and hypertensive rats (SHR) precontracted with prostaglandin F2alpha (PGF2alpha). These relaxations were higher in SHR than WKY arteries. 2. L-N(G)-nitroarginine methyl ester (L-NAME) and 2-amine-5,6-dihydro-6-methyl-4H-1,3-tiazine (AMT), unspecific and inducible NOS (iNOS) inhibitors, respectively, reduced those relaxations, specially in SHR. 3. Four- and seven-hours incubation with dexamethasone reduced the relaxations in MCAs from WKY and SHR, respectively. 4. Polymyxin B and calphostin C, protein kinase C (PKC) inhibitors, reduced the L-Arg-induced relaxation. 5. Lipopolysaccharide (LPS, 7 h incubation) unaltered and inhibited these relaxations in WKY and SHR segments, respectively. LPS antagonized the effect polymyxin B in WKY and potentiated L-Arg-induced relaxations in SHR in the presence of polymyxin B. 6. The contraction induced by PGF2alpha was greater in SHR than WKY arteries. This contraction was potentiated by dexamethasone and polymyxin B although the effect of polymyxin B was higher in SHR segments. LPS reduced that contraction and antagonized dexamethasone- and polymyxin B-induced potentiation, these effects being greater in arteries from SHR. 7. These results suggest that in MCAs: (1) the induction of iNOS participates in the L-Arg relaxation and modulates the contraction to PGF2alpha; (2) that induction is partially mediated by a PKC-dependent mechanism; and (3) the involvement of iNOS in such responses is greater in the hypertensive strain.

Effect of acute and long-term treatment with 17-beta-estradiol on the vasomotor responses in the rat aorta. (8/3789)1. This study sought to evaluate whether the effects of acute and long-term treatment with 17-beta-estradiol on the vasomotor responses in rat aortic rings are mediated through the same mechanism. 2. Ovariectomized rats were treated daily with either 17-beta-estradiol-3-benzoate (100 microg kg(-1)) or vehicle for 1 week. 3. The effect of long-term 17-beta-estradiol treatment on the responses to cumulative doses of phenylephrine, 5-HT, calcium, potassium and 17-beta-estradiol was determined in aortic rings. In the same rings, the effect of acute exposure to 17-beta-estradiol (5 and 10 microM) on the dose response curves for phenylephrine, 5-HT, calcium, potassium and acetylcholine were estimated. The measurements were made in rings with and without intact endothelium. The tone-related basal release of nitric oxide (NO) was measured in rings with intact endothelium. 4. Long-term 17-beta-estradiol treatment reduced the maximum developed contraction to all contracting agents studied. This effect was abolished in endothelium denuded vessels. Acute 17-beta-estradiol treatment also reduced maximal contraction. This effect, however, was independent of the endothelium. 5. Long-term 17-beta-estradiol treatment significantly increased the ability of the rings to dilate in response to acetylcholine whereas acute exposure to 17-beta-estradiol had no effect. The tone-related release of NO was significantly increased after long-term exposure to 17-beta-estradiol. 6. In conclusion, this study indicate that the acute and long-term effects of 17-beta-estradiol in the rat aorta are mediated through different mechanisms. The long-term effect is mediated through the endothelium most likely by increasing NO release. In contrast, the acute effect of 17-beta-estradiol seems to be through an effect on the vascular smooth muscle cells. (+info)
Isolated perfused mesenteric arteries of portal vein ligated and sham-operated rats were contracted by methoxamine (3 nmol-3 mumol) and then treated with nitric oxide synthase inhibitor NG-nitro-L-arginine methyl ester (100 microM), terlipressin or the selective V2 receptor agonist desmopressin (each 0.5 uM). Terlipressin alone reduced and in combination with NG-nitro-L-arginine methyl ester abolished the difference in reactivity to methoxamine between the portal vein ligated and sham-operated groups ...
Behavioral role for nitric oxide in chemosensory activation of feeding in a mollusc | Journal of Neuroscience
A role for the NO-cGMP pathway in mediating chemosensory activation of feeding is suggested by intense NADPH diaphorase staining observed in nerve fibers that project from sensory cells in the lips to the CNS and by the presence in the CNS of a NO-activated guanylyl cyclase. In preparations reduced to isolated lips and CNS, intracellular recordings were made from motoneurons driven by the interneurons of the central pattern generator (CPG) for feeding. Fictive feeding in such preparations can be recorded from these motoneurons following the application of sucrose to the lips. Sucrose activation of fictive feeding is inhibited by the NO scavenger hemoglobin, the NO synthase inhibitor N omega-Nitro-L-Arginine Methyl Ester (L-NAME) and by methylene blue, an inhibitor of guanylyl cyclase. Fictive feeding in isolated lip-CNS preparations can be activated without sucrose by superfusion of NO donor molecules such as SNAP and hydroxylamine and by the nonhydrolyzable analog of cGMP, 8-bromo-cGMP. The ...

Blood Pressure and Vascular Effects of Endothelin Blockade in Chronic Nitric Oxide-Deficient Hypertension | Hypertension
In the present study, chronic administration of bosentan, an antagonist of both ETA and ETB receptors, had no significant effect on the systolic BP level reached after 6 weeks of L-NAME treatment, confirming the observation that acute (60 minutes) administration of the selective ETA receptor antagonist BQ-123 could not lower BP in rats treated for 3 weeks with an l-arginine analogue.21 However, the delay in the BP elevation occurring when bosentan was added to L-NAME would suggest that ET is involved in the early hypertensive response to the l-arginine analogue. This observation is in line with studies showing a blunted hypertensive effect of acute L-NAME administrations by ET receptor antagonists12 13 14 and provides experimental evidence to explain the discrepancy in the efficacy of ET receptor antagonists in acute and chronic L-NAME-induced hypertension.. Chronic administration of L-NAME leads to eutrophic remodeling of the basilar artery, as we previously reported.15 The structural ...

The purpose of this study was to examine the effects of nitric oxide on systemic hemodynamics and oxygen metabolism following acute hepatic inflow occlusion. Fourteen mongrel pigs received solvent (control group, n = 4), the nitric synthesis inhibitor NG-nitro-L-arginine methyl ester (L-NAME group, n = 5), or the substrate for nitric oxide synthesis L-arginine (L-arginine group, n = 5) 30 min before hepatic inflow occlusion. Following 30 min of hepatic ischemia, all livers were reperfused. While all pigs in the control group and L-arginine group survived more than 7 days after reperfusion, two of five pigs in the L-NAME group died during hepatic ischemia period. However, venous oxygen saturation was significantly lower during and after ischemic period, oxygen extraction ratio was significantly higher during hepatic ischemic period in L-NAME group, and systemic vascular resistance was also significantly higher 5 and 15 min after hepatic inflow occlusion. Furthermore, lactate/pyruvate ratio was ...

Role of PKC in the novel synergistic action of urotensin II and angiotensin II and in urotensin II-induced vasoconstriction |...
The intracellular signaling of human urotensin II (hU-II) and its interaction with other vasoconstrictors such as ANG II are poorly understood. In endothelium-denuded rat aorta, coadministration of hU-II (1 nM) and ANG II (2 nM) exerted a significant contractile effect that was associated with increased protein kinase C (PKC) activity and phosphorylation of PKC-α/βII and myosin light chain, whereas either hU-II or ANG II administered alone at these concentrations had no statistically significant effect. This synergistic effect was abrogated by the PKC inhibitor chelerythrine (10 and 30 μM), the selective PKC-α/βII inhibitor Gö-6976 (0.1 and 1 μM), the hU-II receptor ligand urantide (30 nM and 1 μM), or the ANG II antagonist losartan (1 μM). Moreover, in endothelium-intact rat aorta, the synergistic effect of hU-II and ANG II was not exerted any longer, and this synergistic effect was unmasked by pretreatment of the nitric oxide synthase inhibitor NG-nitro-L-arginine methyl ester. hU-II ...

TY - JOUR. T1 - Linalool elicits vasorelaxation of mouse aortae through activation of guanylyl cyclase and K+ channels. AU - Kang, Purum. AU - Seol, Geun Hee. N1 - Publisher Copyright: © 2015 Royal Pharmaceutical Society.. PY - 2015/5/1. Y1 - 2015/5/1. N2 - Objectives The aim of this study was to investigate the cardiovascular relaxing properties of monoterpene alcohol (-)-linalool (LIN), a principal component of several aromatic plants. Methods We assessed the effects of LIN on vascular contractility in mouse aortae and evaluated its underlying mechanisms of action. Key findings We found that LIN dose-dependently relaxed the vascular tonus of mouse thoracic aortae induced by prostaglandin F2 alpha (PGF2α, 3 μm). This effect, however, was reduced by pretreatment with the nitric oxide synthase inhibitor L-NAME (30 μm).

Of all cancer types, prostate cancer is the second most common one with an age-standardized incidence rate of 29.3 per 100,000 men worldwide. Nitric oxide (NO) is both a radical and versatile messenger molecule involved in many physiological activities. NO was documented to be highly secreted and utilized by cancer cells. N omega-nitro-l-arginine methyl ester (L-NAME) is utilized for inhibiting NO synthase. Its worst long-term side effect is reported to be hypertension, hence less cytotoxic than chemotherapeutic agents. Herein, we carried out a cytotoxicity study on how different doses of L-NAME affect DU145 human prostate cancer cells. First, toxic doses of L-NAME were determined. Then, while antioxidant capacity was determined by glutathione and total antioxidant status, oxidative stress was evaluated by quantifying malondialdehyde, NO, and total oxidant status levels. Inflammatory effects of L-NAME were investigated by measuring tumor necrosis factor-alpha and interleukin-6 (IL-6) levels. ...
Serval - Effects of chronic NO synthase inhibition in rats on renin-angiotensin system and sympathetic nervous system.
This study was designed to assess the role of renin and of the sympathoadrenal system in the maintenance of the hypertension induced by chronic nitric oxide synthase (NOS) inhibition in rats kept on a normal (RS) or a low-sodium (LS) diet. With the administration of NG-nitro-L-arginine methyl ester (L-NAME) in drinking water (0.4 milligrams) for 6 wk, mean intra-arterial blood pressure rose to a similar extent to 201 mmHg in the RS and 184 mmHg in the LS animals. Simultaneously, plasma norepinephrine was increased to 838 and 527 pg/ml and epinephrine to 2,041 and 1,341 pg/ml in RS and LS, respectively. Plasma neuropeptide Y levels did not change. Plasma renin activity rose to 21 ng.ml-1.h-1 in RS but remained at 44 ng.ml-1.h-1 in the LS. Both losartan (10 mg/kg) and phentolamine (0.1 mg/kg) intravenous bolus injections reduced blood pressure considerably in the L-NAME hypertensive animals. Whole brain NOS activity was reduced by 84%. Hypertension induced by chronic NOS inhibition in LS

Previous studies identified a region on chromosome 1 associated with NG-nitro-L-arginine methyl ester (L-NAME) hypertension-induced renal disease in fawn-hooded hypertensive (FHH) rats. This region contains a mutant γ-adducin (Add3) gene that impairs renal blood flow (RBF) autoregulation, but its contribution to renal injury is unknown. The present study evaluated the hypothesis that knockout (KO) of Add3 impairs the renal vasoconstrictor response to the blockade of nitric oxide synthase and enhances hypertension-induced renal injury after chronic administration of L-NAME plus a high-salt diet. The acute hemodynamic effect of L-NAME and its chronic effects on hypertension and renal injury were compared in FHH 1Brown Norway (FHH 1BN) congenic rats (WT) expressing wild-type Add3 gene versus FHH 1BN Add3 KO rats. RBF was well autoregulated in WT rats but impaired in Add3 KO rats. Acute administration of L-NAME (10 mg/kg) raised mean arterial pressure (MAP) similarly in both strains, but RBF and ...
ABSTRACT Objective: To evaluate the role of nitric oxide (NO) in pioglitazone (PIO) mediated anti-inflammatory activity in ulcerative colitis. Material and methods: Ulcerative colitis was induced in rats by intracolonical administration of 2, 4, 6-tri-nitrobenzene sulphonic acid (50mg/rat) after 10 days of initiation of treatment except in vehicle control group. Animals were randomly divided into five groups with six animals each. The groups received vehicle, TNBS, PIO, PIO+L-NAME (N-nitro-L-arginine methyl ester), L-NAME for 18 days respectively. PIO (25 mg/kg/day p.o) treatment for 18 days reduced mucosal damage induced by TNBS which was reflected by improvement in body weight, morphological grades of colon, reduced myeloperoxidase activity and histopathological studies. Administration of L-NAME (40 mg/kg/day, p.o) for 18 days in PIO+TNBS treated animals showed exaggerated mucosal damage as compared to PIO+TNBS treated animals. Results: Findings indicate that L-NAME altered the protective ...

The present results showed that i.p. administration of IL-1β in freely moving rats induced a biphasic increase in mean arterial blood pressure, and that a rise in the plasma concentration of NOx occurred during the second phase of the pressor response (at 3 h after the injection of IL-1β). Furthermore, systemic pretreatment with DEX enhanced the second phase of the pressor response, thus confirming our previous finding (Watanabe et al., 1996), and inhibited the evoked increase in the plasma level of NOx. These results suggest that NO is involved as a vasodilator in the regulation of the late phase of the pressor response, and that the enhancement by DEX of the IL-1-induced rise in blood pressure was, at least in part, due to its inhibition of NO release. This idea is further supported by the finding that one of the most frequently used nonselective NOS inhibitors,l-NAME, both enhanced the IL-1β-induced pressor response and attenuated the NOx response seen in this study. This result indicates ...
