Nitric Oxide
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.

Theophylline
A methyl xanthine derivative from tea with diuretic, smooth muscle relaxant, bronchial dilation, cardiac and central nervous system stimulant activities. Theophylline inhibits the 3',5'-CYCLIC NUCLEOTIDE PHOSPHODIESTERASE that degrades CYCLIC AMP thus potentiates the actions of agents that act through ADENYLYL CYCLASES and cyclic AMP.

Ophthalmoscopic abnormalities in adults with falciparum malaria. (1/956)
We studied 424 adults with falciparum malaria admitted over 28 months. They were divided into three groups: cerebral malaria (n = 214); severe non-cerebral malaria (n = 58); and uncomplicated malaria (n = 152). Fundus examination was done daily from admission to discharge, and weekly thereafter in those with persistent changes. All patients were treated by a protocol based on WHO guidelines. Ophthalmoscopic abnormalities were: retinal haemorrhages, 40 (9.43%) (25 cerebral malaria, 10 severe non-cerebral and five uncomplicated malaria); papilloedema, 17 (7.94%) cerebral malaria and two uncomplicated malaria; blurring of disc margins, 25 (11.68%) cerebral and seven non-cerebral; retinal oedema, six (2.80%) cerebral and five non-cerebral malaria; disc pallor, five patients all with cerebral malaria; vitreous haemorrhage and hard exudate in one patient each, both cerebral malaria. Retinal haemorrhage was associated with cerebral malaria and severe non-cerebral malaria, especially with severe anaemia (p < 0.001), as compared to uncomplicated malaria (p < 0.01). The association of papilloedema and cerebral malaria was highly significant compared to severe non-cerebral malaria (p < 0.001). None of these findings was associated with statistically significant mortality, except disc pallor in cerebral malaria (p < 0.05). (+info)Endothelial function in Marfan syndrome: selective impairment of flow-mediated vasodilation. (2/956)
BACKGROUND: The cardiovascular complications of Marfan syndrome arise due to alterations in the structural and functional properties of fibrillin, a constituent of vascular connective tissues. Fibrillin-containing microfibrils are closely associated with arterial endothelial cells, indicating a possible functional role for fibrillin in the endothelium. Plasma concentrations of endothelial cell products are elevated in Marfan subjects, which indirectly indicates endothelial dysfunction. This study directly assessed flow- and agonist-mediated endothelium-dependent brachial artery reactivity in Marfan subjects. METHODS AND RESULTS: In 20 Marfan and 20 control subjects, brachial artery diameter, blood flow, and blood pressure were measured by ultrasonic wall tracking, Doppler ultrasound, and photoplethysmography, respectively. Measurements were taken during hand hyperemia (a stimulus for endothelium-derived nitric oxide [NO] release in the upstream brachial artery) and after sublingual administration of the endothelium-independent vasodilator nitroglycerin. In 9 Marfan and 6 control subjects, the above parameters were also assessed during intra-arterial infusions of acetylcholine and bradykinin (agonists that stimulate NO production) and NG-monomethyl-L-arginine (L-NMMA, an inhibitor of NO production). Flow-mediated responses differed markedly between Marfan and control subjects (-1.6+/-3.5% versus 6. 50+/-4.1%, respectively; P<0.0001), whereas nitroglycerin produced similar vasodilation (14.2+/-5.7% versus 15.2+/-7.8%; P=NS). Agonist-induced vasodilation to incremental intra-arterial infusions of acetylcholine and bradykinin were not significantly different between Marfan and control subjects, and intra-arterial L-NMMA produced similar reductions in brachial artery diameter in both groups. CONCLUSIONS: These data demonstrate impaired flow-mediated but preserved agonist-mediated endothelium-dependent vasodilation in Marfan subjects and suggest preservation of basal NO release. Selective loss of flow-mediated dilation suggests a role for fibrillin in endothelial cell mechanotransduction. (+info)Trigeminal and carotid body inputs controlling vascular resistance in muscle during post-contraction hyperaemia in cats. (3/956)
1. In anaesthetized cats, the effects of stimulation of the receptors in the nasal mucosa and carotid body chemoreceptors on vascular resistance in hindlimb skeletal muscle were studied to see whether the responses were the same in active as in resting muscle. The measurements of vascular resistance were taken, first, in resting muscle, and second, in the immediate post-contraction hyperaemic phase that followed a 30 s period of isometric contractions. 2. Stimulation of the receptors in the nasal mucosa caused reflex apnoea and vasoconstriction in muscle. The latter response was attenuated when the test was repeated during post-contraction hyperaemia. 3. Stimulations of the carotid bodies were made during a period of apnoea evoked reflexly by electrical stimulation of both superior laryngeal nerves. This apnoea prevented any effects of changes in respiration on the carotid body reflex vascular responses. Stimulation of the carotid bodies evoked hindlimb muscle vasoconstriction. In the post-contraction hyperaemic period, the response was reduced or abolished. A similar attenuation of the reflex vasoconstrictor responses occurred in decentralized muscles stimulated through their motor roots in the cauda equina. 4. Evidence is presented that the attenuation of the vasoconstrictor responses evoked by the two reflexes is a phenomenon localized to the contracting muscles themselves resulting from an interaction between sympathetic neuronal activity and the local production of metabolites. 5. The results are discussed in relation to the metabolic needs of tissues in relation to asphyxial defence mechanisms such as occur in the diving response. (+info)Neurogenic origin of articular hyperemia in early degenerative joint disease. (4/956)
It has been speculated that joint instability resulting from anterior cruciate ligament (ACL) rupture could be exacerbated by changes in vasomotor activity in the remaining supporting structures. In this study, the effect of ACL transection on medial collateral ligament (MCL) basal perfusion and its responsiveness to calcitonin gene-related peptide (CGRP) and sympathetic adrenergic influences was examined. Using urethan-anesthetized rabbits, we tested the effects of CGRP and its antagonist CGRP-(8-37) by topical application of these agents to the exposed knee while sympathetic influences were tested by electrically stimulating the saphenous nerve. It was found that MCL basal perfusion was elevated in ACL-sectioned joints; however, this effect was abrogated by prior resection of the articular nerve supply. At the doses tested, the normal vasodilator response to CGRP was abolished in ACL-sectioned joints, whereas the response to CGRP-(8-37) was attenuated. Even under the influence of increased constrictor tone, MCL and capsule blood vessels still showed substantially reduced responses to exogenous CGRP administration. By contrast, nerve-mediated constrictor responses were mostly unaffected by joint instability. This study suggests that posttraumatic knee joint hyperemia is neurogenically mediated, possibly by increased secretion of CGRP. (+info)Endothelial function is impaired in fit young adults of low birth weight. (5/956)
OBJECTIVE: Non-insulin-dependent diabetes, hypertension and ischaemic heart disease, with insulin resistance, are associated with low birth weight (the 'Small Baby Syndrome'). Common to these adult clinical conditions is endothelial dysfunction. We tested the hypothesis that endothelial dysfunction could precede their development in those of low birth weight. METHODS: Endothelial function was measured by ultrasonic 'wall-tracking' of flow-related brachial artery dilatation in fit 19-20 year old subjects randomly selected (blind to the investigators throughout the study) from low (< 2.5 kg) and normal (3.0-3.8 kg) birth weight subjects in the 1975-7 cohort of the Cardiff Births Survey and with no known cause for endothelial dysfunction. RESULTS: Flow-related dilatation was impaired in low birth weight relative to normal birth weight subjects (median 0.04 mm [1.5%] [n = 22] cf. 0.11 mm [4.1%] [n = 17], p < 0.05; 0.04 mm [1.5%] [n = 15] cf. 0.12 mm [4.4%] [n = 12], p < 0.05 after exclusion of inadvertently included ever-smokers). CONCLUSION: The findings suggest that endothelial dysfunction is a consequence of foetal malnutrition, consistent with contributing to the clinical features of the 'Small Baby Syndrome' in later adult life. (+info)The association between laser Doppler reactive hyperaemia curves and the distribution of peripheral arterial disease. (6/956)
OBJECTIVES: To determine whether postocclusive laser Doppler fluxmetry (LDF) curves can be related to the arteriographic distribution of disease. DESIGN: Prospective study. MATERIALS: Sixty-nine patients with symptomatic peripheral ischaemia and 15 healthy subjects. METHODS: Laser Doppler fluxmetry (LDF) was monitored on the dorsum of the symptomatic foot following 2 min of arterial occlusion at the ankle. During reperfusion three patterns of LDF were identified (types I-III). All patients subsequently underwent arteriography which was reported independent of LDF results. The distribution of disease, particularly patency of below-knee vessels, was related to the type of LDF curve observed during reactive hyperaemia. RESULTS: Type I curves were observed in all healthy subjects and 75% of patients with a single arterial lesion. Type II curves were found in 78% of patients with multiple lesions above the knee. The presence of either a type I or II curve was associated with a continuous vessel from knee to ankle (positive predictive value 83%, p < 0.01), whilst type III curve was associated with discontinuous infrapopliteal run-off (positive predictive value 86%, p < 0.01). CONCLUSIONS: This pilot study suggests that post-occlusive LDF curves may identify the distribution of arterial disease and may be useful in the non-invasive management of peripheral ischaemia. (+info)Inhibition of phospholipase A2 attenuates functional hyperemia in the hamster cremaster muscle. (7/956)
Arachidonic acid (AA) is the common precursor for several vasodilatory factors involved in the local control of blood flow. This study was designed to determine the role of phospholipase A2 (PLA2) and AA release in functional hyperemia in the hamster cremaster muscle. The muscle was prepared for in vivo microscopy and subjected to electrical field stimulation for 1 min. First- and second-order arterioles dilated in response from a mean diameter of 66 +/- 5 to 88 +/- 7 micrometer (n = 6). PLA2 was then inhibited with quinacrine (3 x 10(-6) M) for 60 min. PLA2 inhibition was verified by an attenuation of thrombin-induced vasodilation (2 U/ml). Quinacrine had no effect on resting arteriolar diameter but completely abolished functional hyperemia. Quinacrine also had no effect on dilation induced by superfusion of the preparation with 3 x 10(-6)-10(-5) M AA, 10(-6)-10(-4) M adenosine, or 10(-6)-10(-4) M sodium nitroprusside, ruling out nonspecific effects of quinacrine on smooth muscle contractility. These results indicate that functional hyperemia in the hamster cremaster muscle is dependent on PLA2 activation and the availability of AA. (+info)Abnormalities of vascular endothelial function may contribute to increased coronary heart disease risk in UK Indian Asians. (8/956)
OBJECTIVE: To test the hypothesis that abnormalities of endothelial function are present in Indian Asians and may contribute to their increased coronary heart disease risk. SETTING: Single centre in west London. PATIENTS: 26 Indian Asian and 18 European white healthy male subjects, aged 35 to 61 years recruited from general practice lists. DESIGN: Brachial artery diameter responses to reactive hyperaemia and sublingual glyceryl trinitrate were compared using high resolution ultrasound. RESULTS: Mean (SEM) flow mediated, endothelium dependent dilatation was reduced in Indian Asians compared with European whites, at 3.2 (0.8)% v 5.9 (1.0)%, p = 0.03. In contrast, there were no significant differences in baseline brachial arterial diameter (4.6 (0.1) v 4.6 (0.1) mm, p = 0.65) or glyceryl trinitrate induced dilatation (18.8 (1.5)% v 18.5 (1.7)%, p = 0.90) between Indian Asians and European whites, respectively. Univariate analysis showed that Indian Asian race was significantly associated with impaired flow mediated dilatation (regression coefficient = -2.8 (1.3)%, p = 0.03), and in multivariate analysis, this relation was independent of both conventional coronary heart disease risk factors and markers of insulin resistance. CONCLUSIONS: Endothelial function is impaired in healthy UK Indian Asians compared with European whites, and the defect is not accounted for by major coronary heart disease risk factors. Endothelial function may be modulated by novel risk factors in Indian Asians. (+info)

- The main outcome variable tested was postprandial endothelial function after a high-fat meal (900 kcal), as evaluated by use of flow-mediated dilation (FMD) and Framingham reactive hyperemia index (fRHI), after each treatment. (inrae.fr)
Edema3
- Two hypotheses, normal perfusion pressure breakthrough (NPPB) and occlusive hyperemia, prevail in the literature regarding the occasional development of hemorrhage and edema following AVM resection. (elsevier.com)
- Since the occlusive hyperemia hypothesis was first postulated in 1993, however, a debate has persisted within the cerebrovascular community concerning which hypothesis better explains the complications of edema and hemorrhage seen after AVM resection. (elsevier.com)
- There may also be evidence of edema or hyperemia. (nih.gov)
Arterial2
- Puede deberse a un incremento del flujo de sangre en determinada area (activa o arterial) o a una obstrucción del drenaje sanguíneo de dicha area (pasiva o venosa). (bvsalud.org)
- Hyperemia can be due to increase of blood flow into the area (active or arterial), or due to obstruction of outflow of blood from the area (passive or venous). (bvsalud.org)
Vasodilation3
- Images of the same eyes were captured with a range of bulbar hyperaemia caused by vasodilation. (bmj.com)
- Post-ischemic vasodilation in the heart, known as coronary reactive hyperemia (CRH), protects against potential damage to the heart muscle caused by ischemia. (elsevier.com)
- At the end of administration, ATQ and PQ at three doses induced decreased PG, increased ACTH, increased adrenal weight and size, and pathological lesions in the adrenal gland and ovary, including vasodilation and hyperemia in the adrenal cortex and medulla as well as hyperplasia and vacuolar degeneration, ovarian corpus luteum surface hyperemia, numerous but small corpus luteum, and disordered follicle development.

Venous engorgement1
- venous hyperaemia of the brain and general venous engorgement. (abchomeopathy.com)
Episcleral1
- In animals with sepsis, hyperemia of the episcleral vessels, dehydration and severe apathy were observed. (ufrgs.br)
Lesions1
- Autopsies revealed hyperemia and hemorrhagic lesions of most organs. (cdc.gov)
Severe1
- Spacing of impulses was of some significance in that in Group 1, nine subjects developed tinnitus and six had medium or severe hyperemia around the malleus, while among Group 2 subjects, hyperemia was seen only in one subject. (cdc.gov)
Endothelial1
- In diabetic patients , there is a deterioration in the vasodilator response to the reactive hyperemia maneuver compared to healthy subjects , which depends in part on endothelial and autonomic dysfunction. (bvsalud.org)
Baseline2
- RH-PAT index, a measure of reactive hyperemia, was calculated as the ratio of the digital pulse volume during reactive hyperemia divided by that at baseline. (elsevier.com)
- Reactive hyperemia and baseline pulse amplitude among smelter workers exposed to fine and ul. (stami.no)
Tissues1
- The hyperaemia represented by the area under the second exponential makes a greater contribution to the total flows in non‐muscular tissues. (elsevier.com)
Cardiac2
Exposure2
- Study participants showed a significant increase in limbal hyperemia and worse staining results upon exposure. (reviewofoptometry.com)
- Participants in each cluster showed a significant increase in limbal hyperemia and staining after dry environment exposure. (reviewofoptometry.com)
Increase1
- Reactive hyperemia" describes the increase in muscle blood flow that occurs during high-intensity resistance exercise and produces the "pump" associated with increases in muscle size. (fredmeyer.com)
Response1
- Hyperemia is generally an active process that represents a physiological response to localized tissue requirements, potentially reactive to some injury process, and should not in and of itself be considered a pathogenic process. (pathwaymedicine.org)
Clinical3
- The NITRAFLEX pre-training formula contains ingredients that in vitro, animal and clinical studies suggest possess properties that may help advanced athletes maximize energy, intensity, vascularity and reactive hyperemia (pumps) during their workouts, and provide long-term support of testosterone and nitric oxide levels in the healthy range when used as directed.
