Oxidative stress is the key factor that strengthens free radical generation which stimulates lung inflammation. The aim was to explore antioxidant, bronchodilatory along with anti-asthmatic potential of folkloric plants and the aqueous methanolic crude extract of Ipomoea nil ( In.Cr ) seeds which may demonstrate as more potent, economically affordable, having an improved antioxidant profile and providing evidence as exclusive therapeutic agents in respiratory pharmacology. In vitro antioxidant temperament was executed by DPPH, TFC, TPC and HPLC in addition to enzyme inhibition (cholinesterase) analysis; a bronchodilator assay on rabbit's trachea as well as in vivo OVA-induced allergic asthmatic activity was performed on mice...

Background: The developing lung is uniquely susceptible and may be at increased risk of injury with exposure to e-cigarette constituents. We hypothesize that cellular toxicity and airway and vascular responses with exposure to flavored refill solutions may be altered in the immature lung. Methods: Fetal, neonatal, and adult ovine pulmonary artery smooth muscle cells (PASMC) were exposed to popular flavored nicotine-free e-cigarette refill solutions (menthol, strawberry, tobacco, and vanilla) and unflavored solvents: propylene glycol (PG) or vegetable glycerin (VG)...

BACKGROUND: Relevant relationship exists between upper and lower airways. Bronchial obstruction is a paramount feature of asthma and its reversibility is considered a diagnostic step for asthma diagnosis. OBJECTIVE: This study aimed at evaluating a large group of children with allergic rhinitis alone for investigating the degree of brochodilation and possible factors related to it. METHODS: Two hundred patients with allergic rhinitis and 150 normal subjects were consecutively evaluated...

Acute exacerbations in chronic obstructive pulmonary disease (COPD) and asthma are potentially life-threatening clinical events that may result in substantial morbidity and mortality. Treatment of these episodes requires the rapid reversal of airway obstruction by decreasing bronchoconstriction and inflammation. Consensus guidelines and recommendations build on stepwise approaches to care, with the mainstay of therapeutic interventions involving brochodilators and often including systemic corticosteroids, oxygen, and other treatments, depending on severity and setting...

Some of the pharmacological properties of two new compounds, choline 6-thiotheophyllinate and the choline salt of 3-isobutyl-1-methyl-6-thioxanthine (M&B 5924), are described. Both these 6-thioxanthines are structurally related to theophylline and pharmacologically they are very similar to that compound, the main differences in their actions being essentially quantitative. They were more potent than choline theophyllinate as bronchodilators on the isolated guinea-pig tracheal ring preparation and as coronary dilators on the dog heart-lung preparation...

The aim of this study was to assess the relevance of immunoinflammatory markers on the response to short acting beta(2)-agonist in acute asthma exacerbation. Thus, we measured serum eosinophil cationic protein (ECP) levels and sIL-2R at acute exacerbation in 52 adult patients with atopic asthma, and assessed forced expiratory volume in 1 s (FEV(1)) before and after the administration of aerosolized salbutamol. After a cumulative dose of salbutamol causing a 10% improvement in FEV(1) from baseline [CD10, i.e...

From all symptoms in palliative medicine those concerning respiration are most excruciating and most difficult to treat. No other symptom is more dependent on psychosocial circumstances and on the atmosphere around the patient. Therefore the relief of respiratory problems is as important as the therapy of pain. A consequent therapy comprises besides drug therapy (adrenocortical steroids, brochodilators, opioids, sedatives and sometimes antibiotics) also physiotherapy and in special cases oncological treatment and radiotherapy...

Data on the outcome of patients with chronic obstructive pulmonary disease (COPD) are limited. We know that the prognosis is poor when respiratory insufficiency develops, but we have little information on the actual cause of death. Epidemiological studies are suitable for the assessment of the prevalence of the disease, but give no details on the actual cause of death. Age and forced expiratory volume in one second (FEV1) have been recognized as the best predictors of mortality in studies designed to quantify survival of COPD patients, particularly when the post-brochodilator value is used, as this provides a better estimate of airway and parenchymal damage...

Salbutamol, a beta 2-adrenergic agonist, is being extensively used in Venezuela as a brochodilator in the treatment of asthma in children. Previous reports have shown oral salbutamol either to inhibit or not to affect growth hormone (GH) secretion. We evaluated the effect of oral salbutamol (0.1 mg/kg every 6 hours for 3 months) on GH secretion in eight prepubertal short children with mild asthma. Levels of GH during sleep (samples taken every 30 minutes from 9 PM to 6 AM) and after GH-releasing hormone ([GHRH] 1 microgram/kg intravenously [IV]) were measured before, at 24 hours, and at 3 months of salbutamol treatment...

RANDOMIZED CONTROLLED TRIAL

The aim of this study was to evaluate if continuous treatment with budesonide or salmeterol influences the bronchodilator response to terbutaline in children with asthma; 23 children, aged 7 to 16 years (mean = 11 years), with mild asthma were treated with inhaled budesonide 100 micrograms b.i.d. and placebo for three weeks in a randomized, double blind crossover study. These treatments were followed by treatment with inhaled salmeterol 50 micrograms b.i.d. for 3 weeks. On the last day of each period a cumulative dose-response experiment with terbutaline in the doses 50, 100, 250 and 500 micrograms (cumulative dose 900 micrograms) was performed...

1. A novel phthalazine analogue taloximine (1-hydroxyimino-4(2-dimethyl-aminoethoxy)-1,2-dihydrophthalazine monohydrochloride monohydrate) stimulated respiration in conscious rabbits at doses of 7 mg/kg and above.2. Taloximine antagonized the depressant action of morphine on respiration in rabbits at doses of 10 mg/kg. At high doses it resuscitated rabbits after they had been given lethal doses of sodium pentobarbitone.3. In in vitro preparations of the trachea or bronchus taloximine was about equiactive with aminophylline...

Bronchial hyperresponsiveness in asthma has been associated with increased numbers of eosinophils and mast cells in the bronchial airway. It is unclear if these cells are important in the pathogenesis of hyperresponsiveness, and the role of mast cells has been discounted because they are effectively stabilized by beta-adrenergic drugs. Because the pathogenesis of asthma in children may be different from that in adults, and to find out if cellular activation is associated with bronchial reactivity, we studied 17 children with mild to moderately severe chronic asthma who had been treated with intermittent brochodilator therapy and compared their bronchial responsiveness to histamine with the levels of eosinophil cationic protein and mast cell tryptase in broncholavage fluid...

Hexoprenaline1, N,N-[2-(3,4-dihydroxyphenyl)-2-hydroxyethyl] hexamethyl-enediamine, sulphate is a selective beta2-adrenoreceptor agonist which is active in man as a bronchodilator by the oral or intravenous routes and by inhalation. It is indicated for use in the treatment of bronchospasm associated with obstructive airways diseases, including asthma, bronchitis and emphysema. Clinical experience and double-blind studies have established that hexoprenaline is an effective bronchodilator. It major advantage over many other many other brochodilators of equal efficacy is its generally low production of side-effects, particularly tremor, palptitations, and tachycardia...
