The present study was undertaken to determine if beta-agonists delivered by nebulizer provide better clinical responses than MDI therapy in status asthmaticus. We divided 28 hospitalized asthmatic patients into three groups. Group 1 received albuterol by MDI with InspirEase. Group 2 received nebulized albuterol. Group 3 received nebulized metaproterenol. Both nebulizer regimens resulted in sign...

The bronchodilator effect of ipratropium bromide (IB) (Atrovent-Sch 1000), 40 micrograms inhaled, and metaproterenol (Met), 1.25 mg in various combinations, was compared in ten allergic asthmatic patients, aged 23 to 63 years. Six combinations were used at random in a double blind study. The following ventilatory functions-FVC, TGV, SGAW, FEV1, FEF 25-75, VEmax, VE50, VE25, were measured at 30 ...

The pH 6.7 Syrian hamster embryo (SHE) cell morphological transformation assay is a short-term in vitro test that has been used to predict rodent carcinogenicity. Previous reports have indicated that the SHE assay has an overall concordance of approximately 80% with the 2 year rodent bioassay. We selected five compounds, genistein, metaproterenol, rotenone, p-anisidine and resorcinol, that had ...

Milner, A. D., and Ingram, D. (1971). Archives of Diseases in Childhood, 46, 502. Bronchodilator and cardiac effects of isoprenaline, orciprenaline, and salbutamol aerosols in asthma. The bronchodilator and cardiac effects of 0-5% isoprenaline, 2 5% orciprenaline, and 0-5% salbutamol, and a placebo solution inhaled as a nebulized mist from a Wright nebulizer were compared with the help of 12 as...

The effect of orciprenaline on uterine activity in 10 women in early induced labour at term with intact membranes was studied. Nine had uterine contractions in response to intravenous oxytocin and one to prostaglandin E(2). The inhibition of uterine contractility was dose-dependent. The effective dose varied between 10 and 20 mug/minute. Tachyphylaxis was not observed. The only significant effe...

a molecular imprinted polymer (mip) was computationally designed and synthesized for the selective extraction of metaproterenol (mtp), from human plasma. in this regards semi empirical mp3 and mechanical quantum (dft) calculations were used to find a suitable functional monomers. on the basis of computational and experimental results, acrylic acid (aa) and dmso:meoh (90:10 %v/v) were found to b...

A new technique for ablation of atrioventricular nodal reentrant tachycardia, using catheter-directed continuous wave Nd-YAG laser light, 1064 nm, via a novel pin-electrode laser catheter, was applied in 10 patients aged 15-63 years (mean 43 years). A total of 22 laser pulses, 1-5 per patient, at 20 or 30 W, of 10-45 s (mean 27 s) were aimed at the postero-inferior aspect of the tricuspid annul...
