N2 - Light induces various vascular tension changes, but these phenomena and their mechanisms remain controversial. We hypothesise that photocontraction results from the thermal effect, and that photorelaxation results from the non-thermal effect of photochemical nitric oxide generation. The isometric tension of a rat aortic ring was measured during laser light irradiation at various wavelengths with constant heat generation. Visible irradiation (458 nm, 514.5 nm) induced either photorelaxation (the tension increment was -20% of the contracted state induced by noradrenaline) or photocontraction (+7.8%); UV irradiation (351 nm) induced only photorelaxation (-41%), and near-IR irradiation (800 nm) produced only ...
TY - JOUR. T1 - Inducible nitric oxide synthase-derived superoxide contributes to hypereactivity in small mesenteric arteries from a rat model of chronic heart failure. AU - Miller, A A. AU - Megson, I L. AU - Gray, G A. PY - 2000. Y1 - 2000. N2 - The aims of this study were to (a) determine whether inducible nitric oxide synthase (iNOS) is expressed in small mesenteric arteries from rats with chronic heart failure (CHF), (b) investigate the functional significance of this potential source of nitric oxide (NO) on vascular responsiveness and (c) investigate the role that superoxide plays in modulating vascular function in these arteries. CHF was induced in male Wistar rats by coronary artery ligation (CAL). In sham-operated rats the ligature was not tied but pulled under the artery. Six weeks after surgery CAL rats had left ventricular (LV) infarctions and elevated LV end-diastolic pressures. Immunoreactive iNOS was found in endothelial cells, vascular smooth muscle cells and in the adventitia of ...

Nitric oxide is a significant biologic mediator in a number of physiologic processes. Clinical and laboratory studies in both human and animal models have uncovered a number of conditions responsive to nitric oxide therapy. The use of inhaled nitric oxide is rapidly expanding into neonatal and pediatric critical care. Presently, the primary clinical indication for nitric oxide is pulmonary hypertension of either a primary or secondary etiology. Some patient populations that are refractory to conventional management demonstrate significant improvement when receiving nitric oxide therapy. This article discusses the physiologic properties of nitric oxide, as well as its diagnostic and therapeutic indications. Specific issues regarding nitric oxide delivery, monitoring, safety standards, and nursing care are also addressed. ...
The letter by Drs Mair and Puschendorf gives us an opportunity to comment on the use of plasma and urinary nitrate and cGMP as indicators of in vivo nitric oxide formation.. Nitric oxide is formed in the vascular endothelium and in other tissues. One of its major targets is the soluble guanylyl cyclase (sGC), which leads to the formation of cGMP. NO is rapidly inactivated through oxidation to nitrite and nitrate; under pathophysiologic conditions, oxidative inactivation may occur even before the sGC has been stimulated.R1 Both cGMP and nitrite/nitrate can be found in conditioned endothelial cell media, in plasma, and in urine. Because the chemical half-life of NO is in the range of seconds, NO itself can hardly be measured in vivo. Two main strategies have therefore been followed to assess NO activity in vivo. One is to determine NO-dependent vasodilation and the other is to measure the metabolites and/or second messenger of NO, nitrite/nitrate and cGMP, as biochemical surrogates for NO. ...

The aim of this investigation was to elucidate the potential sources of nitric oxide in joint tissues and to determine if the production of nitric oxide could be inhibited by dexamethasone or methotrexate, two agents that inhibit other forms of inducible nitric oxide synthase. Methotrexate inhibits the synthesis of biopterin, which is a co- factor for nitric oxide synthase. Explants of human and bovine cartilage and cultured chondrocytes released large amounts of nitrite, the stable end product of nitric oxide, when stimulated with endotoxin, interleukin-1β, or tumor necrosis factorα.

Tilarginine Acetate Injection is a new type of drug that temporarily stops the body from making a bodily substance called nitric oxide. The body may produce excess nitric oxide following severe heart damage leading to shock. During a heart attack, and especially after a blocked artery causing the heart attack is reopened, a large amount of nitric oxide is released into the heart muscle and into the blood. Normally small amounts of nitric oxide are good for the heart and blood vessels. However, when released in large amounts, such as during a heart attack, it may be harmful, by adding to the damage of the heart attack and lowering the hearts ability to pump blood to the body. It may cause blood pressure to be lowered and reduce the amount of blood flow to the bodys vital organs. This may interfere with the bodys organs being able to do their work. If Tilarginine Acetate Injection can stop extra nitric oxide from being made, the performance of the heart and blood flow to the organs may get ...
There are all kinds of supplements out there that claim to build muscle faster, with nitric oxide supplements gaining a lot of attention in particular. Mens fitness magazines are touting nitric oxide supplements as the way to lift heavier and even to prevent erectile dysfunction, and while clinical results are proving that nitric oxide is beneficial, most of these supplements arent the safest on the market. Thankfully, there are far safer and natural ways to boost nitric oxide for a better workout, sex, and heart health.. A gas naturally made by the body to aid in neurotransmission, blood vessel dilation, reduction of blood pressure, and yes, keeping the family jewels in working order, nitric oxide does provide numerous benefits. Without sufficient nitric oxide, we can feel fatigued and worn down. It has the ability to expand blood vessels for better blood flow, which means more oxygen can reach the brain, heart, and other important organs. You can go the supplement route, or you can just ...
Acute injury or chronic circulation problems reduce perfusion, which in turn causes edema or swelling. This added accumulation of fluid pressurizes the nervous system thus causing pain. The swelling also exerts pressure on the capillaries tasked with the responsibility of providing oxygen to the nerves and tissues.. Nitric oxide boosts the arterial flow to the nerves as well as the venous drainage away from the nerves. This prevents any swelling from occurring because all the fluids are drained away from the injured or pressurized region.. According to medical research conducted over a decade ago, nitric oxide was shown to be the mediator of the analgesic effect of morphine and other opioids. The morphine burns to a receptor in the nerve cell and initiates a release of nitric oxide. This causes a diminution in pain which is mediated by cGMP. Therefore, raising the levels of nitric oxide can fight off pain.. The impact of nitric oxide as a reliever of pain is strongly felt in diabetic patients. ...
Enhanced nitric oxide production by macrophages and neutrophils is a critical defense mechanism against many forms of fungal and bacterial infection and tumorogenesis (16). However, the excessive production of nitric oxide by immune cells and nonimmune cells such as endothelial, epithelial, and smooth muscle cells can also lead to tissue damage, as demonstrated by the protective effects of NOS inhibitors in many inflammatory and autoimmune disease models (15). The role of nitric oxide in sepsis has been hotly contested, since pharmacological manipulation of nitric oxide synthesis in septic patients has been shown to be both deleterious and beneficial (11, 19, 23). The deleterious effects of NOS inhibition are related in part to the inability of NOS substrate inhibitors to discriminate between the constitutive and inducible isoforms of NOS, whereas the beneficial effects of these compounds have been attributed to the ability of NOS inhibitors to restore normal cardiovascular function in septic ...
The protective effect of female sex in renal ageing and cardiovascular function is widely accepted, but poorly understood. Previous evidence has suggested a role for the nitric oxide and renin-angiotensin systems, though the precise mechanisms by which they elicit these effects remain elusive. Female animals and humans have increased nitric oxide bioavailability with age in comparison to males, and this effect can be negated by ovariectomy surgery, suggesting an interaction between ovarian steroids and nitric oxide. In addition, studies have shown an upregulation of the angiotensin II type 2 receptor (AT2R) in aged females in comparison with males. Whilst incompletely understood, the AT2R is known to mediate vasodilation, nitric oxide release, and can be modulated by oestrogen. Work in this laboratory has shown that the expression of AT2R, renal ageing, and blood pressure may all be sensitive to the nutritional environment encountered during foetal development ...
There have been few studies that have examined endothelium-dependent relaxation of mouse vessels in vitro. In normal mice, we found that acetylcholine produced relaxation that was markedly attenuated by the nitric oxide synthase inhibitor l-NNA. Thus, relaxation of the normal mouse aorta in response to acetylcholine is mediated in large part by nitric oxide.. Mechanisms that produce impaired endothelial function in atherosclerosis are not completely clear. One possibility is that smaller quantities of nitric oxide are produced by atherosclerotic vessels in response to endothelium-dependent stimuli. This seems unlikely, because levels of mRNA and protein for the endothelial isoform of nitric oxide synthase (NOS III) and the production of nitric oxide in the atherosclerotic rabbit aorta appear to be increased rather than decreased.25 26 We found that vasorelaxation in response to both acetylcholine and A23187 was impaired in the proximal aortas of apoE/LDL receptor-deficient mice, which contained ...
An electrode sensor which may be used to specifically and quantitatively measure nitric oxide is provided, as well as a method of preparing and using such an electrode sensor to measure nitric oxide concentration in solution. A nitric oxide (NO) microsensor based on catalytic oxidation of NO comprises a thermally-sharpened carbon fiber with a tip diameter of about 0.5-0.7 μm coated with several layers of p-type semiconducting polymeric porphyrin and cationic exchanger deposited thereon. The microsensor, which can be operated in either the amperometric, voltammetric or coulometric mode utilizing a two or three electrode system, is characterized by a linear response up to about 300 μM, a response time better than 10 msec and a detection limit of about 10 nM. The sensor of the present invention also discriminates against nitrite, the most problematic interferant in NO measurements. The amount of NO released from a single cell can thus be selectively measured in situ by a porphyrinic microsensor of the
Due to its popularity, hundreds of thousands of people have started consuming nitric oxide supplements. Like most supplements, a number of nutritionists have promoted and stood behind it because of its many benefits. However, just like with anything, there are both positive and negative nitric oxide side effects. The following are just a couple of effects that all users should know.. Nitric oxide has the ability to promote more endurance and energy by helping a users muscles. People often fail to realize how much their bodies depend on the oxygen they breathe. Your muscles need oxygen in order to repair themselves after being worked extensively. Nitric oxide helps with the delivery of oxygen to the muscles by allowing certain muscles to relax. These relaxed muscles allow blood to flow more easily to your tissues so that oxygen can be delivered.. By increasing a persons energy and endurance theyll be less likely to experience fatigue during and after a workout. Its not uncommon for athletes ...

Background and purpose: Previous work has shown that NG-monomethyl-l-arginine (l-NMMA) paradoxically inhibits basal, but not ACh-stimulated activity of nitric oxide in rat aorta. The aim of this study was to determine if the endogenously produced agent, asymmetric NG, NG-dimethyl-l-arginine (ADMA), also exhibits this unusual selective blocking action. Experimental approach: The effect of ADMA on basal nitric oxide activity was assessed by examining its ability to enhance phenylephrine (PE)-induced tone in endothelium-containing rings. Its effect on ACh-induced relaxation was assessed both in conditions where ADMA greatly enhanced PE tone and where tone was carefully matched with control tissues at a range of different levels. Key results: ADMA (100 µM) potentiated PE-induced contraction, consistent with inhibition of basal nitric oxide activity. Higher concentrations (300-1000 µM) had no greater effect. Although ADMA (100 µM) also appeared to block ACh-induced relaxation when it enhanced PE ...

TY - JOUR. T1 - Zn2+ inhibits nitric oxide formation in response to lipopolysaccharides. T2 - Implication in its anti-inflammatory activity. AU - Abou-Mohamed, Gamal. AU - Papapetropoulos, Andreas. AU - D. Catravas, John. AU - Caldwell, Robert W.. PY - 1998/1/12. Y1 - 1998/1/12. N2 - There is compelling evidence to indicate an anti-inflammatory action of Zn2+. Most inflammatory diseases are associated with an increase of the inducible form of nitric oxide (NO) synthase. Additionally, inflammatory mediators such as histamine or bradykinin stimulate the constitutive NO synthase. Thus, the present study was undertaken to investigate whether Zn2+ inhibits production of inducible NO synthase and/or constitutive NO synthase activity to produce NO. Lipopolysaccharide, 5 mg/kg i.v., administered to Zn2+-deficient (ZD) rats, rats supplemented with Zn2+ sulfate (ZG), 10 mg/kg s.c., or controls resulted in a significant reduction of their serum Zn2+. The levels of N(G)-nitro-L-arginine methylester (L- ...
METHODS AND RESULTS The effect of endothelium-derived NO was studied by the addition of specific inhibitors of NO production, L-N-monomethyl arginine (L-NMMA) and N-iminoethyl-L-ornithine (L-NIO), to a perfusion system in which both endothelial cells and their matrices were present. A concentration-dependent increase in platelet adhesion to the matrix was found with a maximum inhibition at a concentration of 2 mM L-NMMA and 0.1 mM L-NIO. The effect was dependent on the presence of endothelial cells, because no increase in platelet adhesion was observed in their absence. The effect of exogenous NO was tested in a specially devised perfusion system in which the NO was introduced at the site of adhesion by means of a porous membrane on which an extracellular matrix of endothelial cells was present. Inhibition of platelet adhesion by NO was found at all shear rates tested and after all perfusion periods. ...

The interaction between inspiratory fraction of O2 (FIO2) and endogenous nitric oxide (NO) regulation of pulmonary vascular tone was examined in intact anesthetized dogs. Stimulus (FIO2 of 1, 0.4, 0.21, 0.12, and 0.1)-response (changes in pulmonary artery pressure minus pulmonary artery occlusion pressure) curves were constructed with cardiac output kept constant (by opening a femoral arteriovenous bypass or inflating an inferior vena cava balloon catheter), before and after administration of compounds acting at different levels of the L-arginine-NO pathway, NG-nitro-L-arginine (L-NNA, 10 mg/kg iv, n = 16), a NO synthase inhibitor, and methylene blue (8 mg/kg iv, n = 16), a guanylate cyclase inhibitor. L-NNA and methylene blue did not influence pulmonary vascular tone in hyperoxic and in normoxic conditions, but they increased it during hypoxia, thus enhancing the vasopressor response to hypoxia (from 4.5 +/- 0.9 to 10.4 +/- 1.2 mmHg and from 4.2 +/- 0.8 to 9 +/- 1.5 mmHg, respectively, both P , ...

Abstract: Leishmaniasis is a disease common in tropical and sub-tropical countries, including India. Current studies suggest that nitric oxide (NO) and peroxynitrite are crucial for elimination of the Leishmania parasites. Rural populations in India use turmeric abundantly in their daily life: as a spice, as a component of cosmetics, as an anti-inflammatory agent and other medications, and as a household topical remedy for minor injuries including insect bites. However, one of the major active principles in turmeric is curcumin, an inhibitor of nitric oxide production and a scavenger of nitric oxide and superoxide anions. Our laboratory has found that curcumin inhibits the gene expression of inducible oxide synthase (iNOS) in vitro and in vivo in a bacterial lipopolysaccharide induction system. It also inhibits the activation of the transcription factor nuclear factor kappaB and the cytokines, tumor necrosis factor-alpha and interleukin-1beta, molecules that play roles in regulating iNOS gene ...
Endogenously or exogenously produced nitric oxide (NO) can cause negative inotropic effects in the cardiovascular system (1-5). Consequently, a great deal of attention is being focused currently on conditions that expose the heart to elevated concentrations of NO. In examining the causes of inflammation-induced myocardial injury, it has been observed recently that the proinflammatory cytokines interferon (IFN)-γ, interleukin (IL)-1β, and tumor necrosis factor (TNF)-α can increase NO synthesis by elevating the expression of inducible nitric oxide synthase (iNOS) (6), causing a sustained depression in myocardial contractility (3,4,7), as well as protracted hypotension during septic shock (8). However, despite this recent elucidation of the conditions that promote NO production in the inflamed heart, mechanisms of the NO-induced injurious effects remain poorly understood.. Two potential mechanisms of NO damage are currently favored. The first invokes an indirect mode of injury in which the ...

Nitric oxide is one of the most important signalling molecules involved in the regulation of physiological function. It first came to prominence when it was discovered that the vascular endothelium of mammals synthesises and releases nitric oxide (NO) to mediate a potent vasodilation. Subsequently, it was shown that NO is synthesised in the endothelium by a specific isoform of nitric oxide synthase (NOS) called NOS3. Following this discovery, it was assumed that an endothelial NO/NOS3 system would be present in all vertebrate blood vessels. This review will discuss the latest genomic, anatomical and physiological evidence which demonstrates that an endothelial NO/NOS3 signalling is not ubiquitous in non-mammalian vertebrates, and that there have been key evolutionary steps that have led to the endothelial NO signalling system being a regulatory system found only in reptiles, birds and mammals. Furthermore, the emerging role of nitrite as an endocrine source of NO for vascular regulation is ...

Our new structures of bacterial Cu,Zn SODs from symbionts and pathogens provide the potential for drug design. Whereas the fold and active-site geometry of bacterial Cu,Zn SODs match those of eukaryotic SODs, the elements recruited to form the dimer interface and the active-site channel are strikingly different (Fig. 1). With our structures and redesign of SODs, we aim to elucidate the structural metallobiochemistry and structure-function relationships of the enzymes. Our new research on the structural and chemical biology of NOSs, which regulate the synthesis and thereby the biological activity of nitric oxide, complements our studies on SODs. Nitric oxide functions at low concentrations as a diffusible, biological messenger for neurotransmission, long-term potentiation, platelet aggregation, and regulation of blood pressure. At higher concentrations, nitric oxide acts as a cytotoxic agent for defense against tumor cells and intracellular parasites. Each NOS subunit is divided into 2 domains ...
