Bradykinin
A nonapeptide messenger that is enzymatically produced from KALLIDIN in the blood where it is a potent but short-lived agent of arteriolar dilation and increased capillary permeability. Bradykinin is also released from MAST CELLS during asthma attacks, from gut walls as a gastrointestinal vasodilator, from damaged tissues as a pain signal, and may be a neurotransmitter.
Baroreflex
A response by the BARORECEPTORS to increased BLOOD PRESSURE. Increased pressure stretches BLOOD VESSELS which activates the baroreceptors in the vessel walls. The net response of the CENTRAL NERVOUS SYSTEM is a reduction of central sympathetic outflow. This reduces blood pressure both by decreasing peripheral VASCULAR RESISTANCE and by lowering CARDIAC OUTPUT. Because the baroreceptors are tonically active, the baroreflex can compensate rapidly for both increases and decreases in blood pressure.

Methylene Blue
A compound consisting of dark green crystals or crystalline powder, having a bronze-like luster. Solutions in water or alcohol have a deep blue color. Methylene blue is used as a bacteriologic stain and as an indicator. It inhibits GUANYLATE CYCLASE, and has been used to treat cyanide poisoning and to lower levels of METHEMOGLOBIN.
Norepinephrine
Precursor of epinephrine that is secreted by the adrenal medulla and is a widespread central and autonomic neurotransmitter. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers and of the diffuse projection system in the brain arising from the locus ceruleus. It is also found in plants and is used pharmacologically as a sympathomimetic.

Sympathetic Nervous System
The thoracolumbar division of the autonomic nervous system. Sympathetic preganglionic fibers originate in neurons of the intermediolateral column of the spinal cord and project to the paravertebral and prevertebral ganglia, which in turn project to target organs. The sympathetic nervous system mediates the body's response to stressful situations, i.e., the fight or flight reactions. It often acts reciprocally to the parasympathetic system.

Phospholamban is present in endothelial cells and modulates endothelium-dependent relaxation. Evidence from phospholamban gene-ablated mice. (1/3024)
Vascular endothelial cells regulate vascular smooth muscle tone through Ca2+-dependent production and release of vasoactive molecules. Phospholamban (PLB) is a 24- to 27-kDa phosphoprotein that modulates activity of the sarco(endo)plasmic reticulum Ca2+ ATPase (SERCA). Expression of PLB is reportedly limited to cardiac, slow-twitch skeletal and smooth muscle in which PLB is an important regulator of [Ca2+]i and contractility in these muscles. In the present study, we report the existence of PLB in the vascular endothelium, a nonmuscle tissue, and provide functional data on PLB regulation of vascular contractility through its actions in the endothelium. Endothelium-dependent relaxation to acetylcholine was attenuated in aorta of PLB-deficient (PLB-KO) mice compared with wild-type (WT) controls. This effect was not due to actions of nitric oxide on the smooth muscle, because sodium nitroprusside-mediated relaxation in either denuded or endothelium-intact aortas was unaffected by PLB ablation. Relative to denuded vessels, relaxation to forskolin was enhanced in WT endothelium-intact aortas. The endothelium-dependent component of this relaxation was attenuated in PLB-KO aortas. To investigate whether these changes were due to PLB, WT mouse aorta endothelial cells were isolated. Both reverse transcriptase-polymerase chain reaction and Western blot analyses revealed the presence of PLB in endothelial cells, which were shown to be >98% pure by diI-acetylated LDL uptake and nuclear counterstaining. These data indicate that PLB is present and modulates vascular function as a result of its actions in endothelial cells. The presence of PLB in endothelial cells opens new fields for investigation of Ca2+ regulatory pathways in nonmuscle cells and for modulation of endothelial-vascular interactions. (+info)Endogenous endothelin-1 depresses left ventricular systolic and diastolic performance in congestive heart failure. (2/3024)
Endothelin-1 (ET-1) is a positive inotrope in normal hearts; however, the direct cardiac effects of endogenous ET-1 in congestive heart failure (CHF) are unknown. We evaluated the cardiac responses to endogenous ET-1 using an ETA and ETB receptor blocker (L-754,142) in seven conscious dogs before and after pacing-induced CHF. Before CHF, when the plasma ET-1 was 7.3 +/- 1.7 fmol/ml, L-754,142 caused no significant alterations in heart rate, left ventricular (LV) end-systolic pressure, total systemic resistance, and the time constant of LV relaxation (tau). LV contractile performance, measured by the slopes of LV pressure (P)-volume (V) relation (EES), dP/dtmax-end-diastolic V relation (dE/dtmax), and stroke work-end-diastolic V relation, was also unaffected. After CHF, when the plasma ET-1 was significantly increased to 14.1 +/- 3.0 fmol/ml (p <.05), L-754,142 produced a significant decreases in LV end-systolic pressure (101 +/- 11 versus 93 +/- 8 mm Hg) and total systemic resistance (0.084 +/- 0.022 versus 0.065 +/- 0.15 mm Hg/ml/min). The tau (42 +/- 12 versus 38 +/- 10 ms), mean left atrial P (22 +/- 5 versus 18 +/- 4 mm Hg) (p <.05), and minimum LVP were also significantly decreased. After CHF, the slopes of P-V relations, EES (3.4 +/- 0.4 versus 4.8 +/- 0.8 mm Hg/ml), dE/dtmax (42.4 +/- 7.8 versus 50.0 +/- 7.8 mm Hg/s/ml), and stroke work-end-diastolic V relation (58.1 +/- 3.3 versus 72.4 +/- 5.2 mm Hg) (p <.05) all increased after L-754,142, indicating enhanced contractility. Before CHF, low levels of endogenous ET-1 have little cardiac effect. However, after CHF, elevated endogenous ET-1 produces arterial vasoconstriction, slows LV relaxation, and depresses LV contractile performance. Thus, elevated endogenous ET-1 may contribute to the functional impairment in CHF in this canine model. (+info)Studies of the role of endothelium-dependent nitric oxide release in the sustained vasodilator effects of corticotrophin releasing factor and sauvagine. (3/3024)
1. The mechanisms of the sustained vasodilator actions of corticotrophin-releasing factor (CRF) and sauvagine (SVG) were studied using rings of endothelium de-nuded rat thoracic aorta (RTA) and the isolated perfused rat superior mesenteric arterial vasculature (SMA). 2. SVG was approximately 50 fold more potent than CRF on RTA (EC40: 0.9 +/- 0.2 and 44 +/- 9 nM respectively, P < 0.05), and approximately 10 fold more active in the perfused SMA (ED40: 0.05 +/- 0.02 and 0.6 +/- 0.1 nmol respectively, P < 0.05). Single bolus injections of CRF (100 pmol) or SVG (15 pmol) in the perfused SMA caused reductions in perfusion pressure of 23 +/- 1 and 24 +/- 2% that lasted more than 20 min. 3. Removal of the endothelium in the perfused SMA with deoxycholic acid attenuated the vasodilatation and revealed two phases to the response; a short lasting direct action, and a sustained phase which was fully inhibited. 4. Inhibition of nitric oxide synthase with L-NAME (100 microM) L-NMMA (100 microM) or 2-ethyl-2-thiopseudourea (ETPU, 100 microM) had similar effects on the vasodilator responses to CRF as removal of the endothelium, suggesting a pivotal role for nitric oxide. However the selective guanylate cyclase inhibitor 1H-[l,2,4]oxadiazolo[4,3-alpha]quinoxalin-1-one (ODQ, 10 microM) did not affect the response to CRF. 5. High potassium (60 mM) completely inhibited the vasodilator response to CRF in the perfused SMA, indicating a role for K channels in this response. 6. Compared to other vasodilator agents acting via the release of NO, the actions of CRF and SVG are strikingly long-lasting, suggesting a novel mechanism of prolonged activation of nitric oxide synthase. (+info)Growth-inhibitory effect of cyclic GMP- and cyclic AMP-dependent vasodilators on rat vascular smooth muscle cells: effect on cell cycle and cyclin expression. (4/3024)
1. The possibility that the antiproliferative effect of cyclic GMP- and cyclic AMP-dependent vasodilators involves an impaired progression of vascular smooth muscle cells (VSMC) through the cell cycle and expression of cyclins, which in association with the cyclin-dependent kinases control the transition between the distinct phases of the cell cycle, was examined. 2. FCS (10%) stimulated the transition of quiescent VSMC from the G0/G1 to the S phase (maximum within 18-24 h and then to the G2/M phase (maximum within 22-28 h). Sodium nitroprusside and 8-Br-cyclic GMP, as well as forskolin and 8-Br-cyclic AMP markedly reduced the percentage of cells in the S phase after FCS stimulation. 3. FCS stimulated the low basal protein expression of cyclin D1 (maximum within 8-24 h) and E (maximum within 8-38 h) and of cyclin A (maximum within 14-30 h). The stimulatory effect of FCS on cyclin D1 and A expression was inhibited, but that of cyclin E was only minimally affected by the vasodilators. 4. FCS increased the low basal level of cyclin D1 mRNA after a lag phase of 2 h and that of cyclin A after 12 h. The vasodilators significantly reduced the FCS-stimulated expression of cyclin D1 and A mRNA. 5. These findings indicate that cyclic GMP- and cyclic AMP-dependent vasodilators inhibit the proliferation of VSMC by preventing the progression of the cell cycle from the G0/G1 into the S phase, an effect which can be attributed to the impaired expression of cyclin D1 and A. (+info)Maintenance of normal agonist-induced endothelium-dependent relaxation in uraemic and hypertensive resistance vessels. (5/3024)
BACKGROUND: The nitric oxide system has been implicated in several diseases with vascular complications including diabetes mellitus and hypertension. Despite the high prevalence of hypertension and cardiovascular complications in renal failure few studies have examined vascular and endothelial function in uraemia. We therefore chose to study possible abnormalities of the nitric oxide vasodilator system in an animal model of chronic renal failure. METHODS: Adult spontaneous hypertensive rats and Wistar Kyoto rats were subjected to a 5/6 nephrectomy with control animals having sham operations. After 4 weeks blood pressure was recorded and the animals were sacrificed. Branches of the mesenteric arteries were isolated and mounted on a Mulvany myograph. All experiments were performed in the presence of indomethacin (10(-5) M). The vessels were first preconstricted with noradrenaline, exposed to increasing concentrations of acetylcholine (10(-8) to 10(-4) M) and subsequently to sodium nitroprusside (10(-5) M). RESULTS: There was no difference in the relaxation of the four groups of vessels to any of the concentrations of acetylcholine used nor was there any significant difference in the EC50s (control Wistar Kyoto 6.1+/-1.4 x 10(-8) M; uraemic Wistar Kyoto 5.4+/-0.8 x 10(-8) M; control spontaneous hypertensive rats 4.5+/-0.6 x 10(-8) M; uraemic spontaneous hypertensive rats 6+/-0.7 x 10(-8) M). Vasodilatation in response to sodium nitroprusside was unchanged in uraemic vessels. In addition the vascular responses to both acetylcholine and sodium nitroprusside were unaltered in spontaneous hypertensive rats. CONCLUSIONS: We conclude that normal agonist-induced endothelium-dependent relaxation is maintained in experimental uraemia and hypertension. (+info)Regulation of sympathetic nerve activity in heart failure: a role for nitric oxide and angiotensin II. (6/3024)
The mechanisms by which sympathetic function is augmented in chronic heart failure (CHF) are not well understood. A previous study from this laboratory (Circ Res. 1998;82:496-502) indicated that blockade of nitric oxide (NO) synthesis resulted in only an increase in renal sympathetic nerve activity (RSNA) when plasma angiotensin II (Ang II) levels were elevated. The present study was undertaken to determine if NO reduces RSNA in rabbits with CHF when Ang II receptors are blocked. Twenty-four New Zealand White rabbits were instrumented with cardiac dimension crystals, a left ventricular pacing lead, and a pacemaker. After pacing at 360 to 380 bpm for approximately 3 weeks, a renal sympathetic nerve electrode and arterial and venous catheters were implanted. Studies were carried out in the conscious state 3 to 7 days after electrode implantation. The effects of a 1-hour infusion of sodium nitroprusside (SNP; 3 microgram . kg-1. min-1) on RSNA and mean arterial pressure (MAP) were determined before and after Ang II blockade with losartan (5 mg/kg) in normal and CHF rabbits. Changes in MAP were readjusted to normal with phenylephrine. Before losartan, SNP evoked a decrease in MAP and an increase in RSNA in both groups that was baroreflex-mediated, because both MAP and RSNA returned to control when phenylephrine was administered. In the normal group, losartan plus SNP caused a reduction in MAP and an increase in RSNA that was 152.6+/-9.8% of control. Phenylephrine returned both MAP and RSNA back to the control levels. However, in the CHF group, losartan plus SNP evoked a smaller change in RSNA for equivalent changes in MAP (117.1+/-4.1% of control). On returning MAP to the control level with phenylephrine, RSNA was reduced to 65.2+/-2.9% of control (P<0. 0001). These data suggest that endogenous Ang II contributes to the sympathoexcitation in the CHF state and that blockade of Ang II receptors plus providing an exogenous source of NO reduces RSNA below the elevated baseline levels. We conclude that both a loss of NO and an increase in Ang II are necessary for sustained increases in sympathetic nerve activity in the CHF state. (+info)Heat shock protein expression in umbilical artery smooth muscle. (7/3024)
Postpartum vasospasm in the umbilical arteries may be due to impaired vasorelaxation secondary to alterations in the expression of heat shock proteins. The contractile responses of pre- and full-term bovine umbilical artery smooth muscles were determined in a muscle bath. Heat shock protein expression was determined in bovine and human arterial tissues using western blotting with specific antisera. Full-term bovine and human umbilical artery smooth muscle was refractory to relaxation induced by the nitric oxide donor, sodium nitroprusside. This impaired vasorelaxation was associated with the expression of the inducible form of the heat shock protein, HSP70i, and increases in the expression of the small heat shock protein, HSP27. Small heat shock proteins have been implicated in modulating contraction and relaxation responses in vascular smooth muscles. Thus, alterations in heat shock protein expression may play a role in umbilical artery vasospasm. (+info)Intrahippocampal infusion of interleukin-6 impairs avoidance learning in rats. (8/3024)
AIM: To study the effect of intrahippocampal infusion of interleukin-6 (IL-6) on active avoidance in rats and the possible involvement of nitric oxide (NO). METHODS: Using a shuttle-box model, the effects of bilaterally intrahippocampal infusion of IL-6 3.2, 16, and 80 ng as well as sodium nitroprusside (SNP) 400 ng on active avoidance were studied on d 8 after administration. The levels of nitrite as an index of NO in the hippocampus were detected using a fluorometric assay 24 h after infusion of IL-6 3.2 or 80 ng. RESULTS: IL-6 16 and 80 ng impaired the acquisition performance of active avoidance by prolonging the latency of avoidance in training, but not the retention performance in testing. IL-680 ng and SNP 400 ng also resulted in a marked impairment in acquisition performances by decreasing the rate of avoidance, but not in retention performances. IL-680 ng markedly elevated the nitrite levels from 10.6 +/- 0.7 in control rats to 13.6 +/- 2.0 (nmol/g wet wt) (P < 0.01). IL-6 3.2 ng had no effect on active avoidance nor on nitrite levels. CONCLUSION: Intrahippocampal infusion of IL-6 impaired learning acquisition of active avoidance in rats. (+info)

Nitrate/Nitrite Toxicity: Clinical Assessment - Evaluation | Environmental Medicine | ATSDR
The signs and symptoms of methemoglobinemia listed in Table 3 can be roughly correlated with the percentage of total hemoglobin in the oxidized form (see "Clinical Assessment-Laboratory Tests"). Unfortunately, because methemoglobin (MetHb) is generally expressed as a percent of total hemoglobin, levels may not correspond with symptoms in some patients. For example, a patient with a MetHb level of 20% and total hemoglobin of 15 grams per deciliter (g/dL) still has 12 g/dL of functioning hemoglobin, whereas a patient with a MetHb level of 20% and total hemoglobin of 8 g/dL has only 6.4 g/dL of functioning hemoglobin. Anemia, acidosis, respiratory compromise, cardiovascular disease, sepsis or the presence of other abnormal hemoglobin species (i.e. carboxyhemoglobin, sulfhemoglobin, sickle hemoglobin (HbS) may make patients more symptomatic than expected for a given MetHb level [Wright et al. 1999; Ash-Bernal et al. 2004; Skold et al. 2011].. Due to the large excess capacity of the blood to carry ...
