The alveolar epithelium plays a critical role in resolving pulmonary edema. We thus hypothesized that its function might be upregulated in rats with heart failure, a condition that severely challenges the lung's ability to maintain fluid balance. Heart failure was induced by left coronary artery ligation. Echocardiographic and cardiovascular hemodynamics confirmed its development at 16 wk postl...

The secretion of lung surfactant requires the movement of lamellar bodies to the plasma membrane through cytoskeletal barrier at the cell cortex. We hypothesized that the cortical cytoskeleton undergoes a transient disassembly/reassembly in the stimulated type II cells, therefore allowing lamellar bodies access to the plasma membrane. Stabilization of cytoskeleton with Jasplakinolinde (JAS), a ...

To examine the tissue distribution and residues after withdrawal of various beta-agonists (i.e., clenbuterol, salbutamol, and terbutaline) 160 1-d-old broiler chickens were assigned to four groups. During treatment (16 to 35 d), the birds were fed a control diet or a diet containing 1 ppm of clenbuterol, 10 ppm of salbutamol, or 10 ppm of terbutaline. After d 35 all groups received the control ...

Forty-eight children with known asthma (ranging in age from 2 to 16 years) were studied during an acute attack. Each received either terbutaline or epinephrine subcutaneously in a random double-blind fashion. Measurement of heart rate, respiratory rate, and systemic arterial systolic and diastolic blood pressures and careful clinical assessment of obstruction of the airway were made before and ...

The effect of terbutaline, in a slow-release preparation, on spirometry and arterial blood-gases, was studied in fourteen patients with nocturnal asthma. The patients were treated with either 15 mg of slow-release terbutaline or placebo given as a single dose at 10 pm for eight days in a double-blind crossover trial. The patients were studied in the hospital for one night at the end of each tre...

The bronchodilating efficacy of terbutaline (250 micrograms.puff) inhaled via the Nebuhaler and salbutamol (100 micrograms.puff) inhaled via the Volumatic has been studied in 30 patients with reversible obstructive airways disease in a randomized crossover study. The salbutamol/Volumatic combination produced significantly greater bronchodilatation than terbutaline/Nebuhaler (one puff, p less th...

Terbutaline is known to be an effective drug in the treatment of asthma which acts by P32 receptor stimulation in the lung.' If given in large doses this agent may produce side effects-such as tremor, headache, and tachycardia. Children seem to be fairly tolerant of such side effects and therefore may continue to obtain benefit at doses higher than currently recommended. The present study was u...

The study aim was to investigate the effect of endogenous insulin release on lipolysis in subcutaneous adipose tissue after adrenergic stimulation in obese subjects diagnosed with type 2 diabetes (T2D). In 14 obese female T2D subjects, or 14 obese non-T2D controls, glycerol concentration was measured in response to the α1,2,ß-agonist norepinephrine, the α1-agonist norfenefrine and the ß2-agonis...

BACKGROUND In mild asthma exercise-induced bronchoconstriction (EIB) is usually treated with inhaled short-acting β2 agonists (SABAs) on demand. OBJECTIVE The hypothesis was that a combination of budesonide and formoterol on demand diminishes EIB equally to regular inhalation of budesonide and is more effective than terbutaline inhaled on demand. METHODS Sixty-six patients with asthma (>12 ...

INTRODUCTION We assessed the in vivo effects of terbutaline, a beta2-agonist assumed to reduce microvascular permeability in acute lung injury. METHODS We used a recently developed broncho-alveolar lavage (BAL) technique to repeatedly measure (every 15 min. for 4 hours) the time-course of capillary-alveolar leakage of a macromolecule (fluorescein-labeled dextran) in 19 oleic acid (OA) lung in...
