A bacterium utilizing the alkaloid (-)-ephedrine as its sole source of carbon was isolated by an enrichment-culture technique from soil supplemented with 4-benzoyl-1,3-oxazolidinon-(2). The bacterium was indentified as Pseudomonas putida by morphological and physiological studies. The following metabolites were isolated from the culture fluid: methylamine, formaldehyde, methylbenzoylcarbinol (2...

The aim of this study was to evaluate the effect of age on the hemodynamic responses to intravenous (IV) ephedrine in pediatric patients anesthetized with halothane, nitrous oxide, and oxygen. One hundred ten pediatric patients, ranging in age from 0.1 to 15 yr, were assigned to receive 0.1 mg/kg (n = 55) or 0.2 mg/kg (n = 55) IV ephedrine. General anesthesia was maintained with 1.0 minimum alv...

Background: Spinal anesthesia is an accepted technique in elective cesarean sections. However, hypotension, resulted from sympathectomy is a common problem, especially in pregnant women. Prevention of this complication by sympathomimetic agents is of potential clinical significance. The aim of this study is to compare the effect of prophylactic infusion of Phenylephrine versus Ephedrine in the ...

The separation of ephedrine-type alkaloids and their enantiomers in raw herbs and commercial herbal products was investigated by carrying out enantioselective separation in the first-dimension column (containing beta-cyclodextrin as the chiral selector) of a comprehensive two-dimensional gas chromatography (GC x GC) system, whereas a polar polyethylene glycol capillary column was used for separ...

Ephedrine, an α1 and β agonist, that increases blood flow to muscles thus the cardiac output. This concept is used in this study as speed by which drug reaches neuromuscular junction partly determines onset of action muscle relaxants. Our hypothesis was ephedrine could hasten rocuronium bromide. The time shorter after administration there no difference laryngoscopic viewsand hemodynamics betwee...

Bala is important medicinal plant of Ayurvedic system of medicine. Previous works have reported presence of ephedrine in Bala although it has not been reported in other varieties of Bala. Extracts of Sida cordifolia standardized to ephedrine are available in the Indian as well as international market. In western world ephedrine once upon a time was widely used for weight loss but recently it ha...

BACKGROUND The aim of this randomized, double-blind, placebo-controlled study was to evaluate dose effects of ephedrine pretreatment on the onset time and intubating conditions after cisatracurium administration. METHODS A total of 140 adult patients were randomized into 4 groups to receive either 30 µg/kg ephedrine (Group 30, n = 35), 70 µg/kg ephedrine (Group 70, n = 35), 110 µg/kg ephedrin...

BACKGROUND The authors have previously observed an apparent association between rostral spread of spinal anesthesia and choice of intravenous vasopressor given to maintain maternal systolic arterial pressure during cesarean delivery. This study tested the hypothesis that an intravenous infusion of phenylephrine can reduce rostral spread of spinal anesthesia in pregnancy, compared with ephedrine...

AIMS To determine whether the federal regulation of ephedrine and pseudoephedrine, precursors used in illicit methamphetamine production, reduced methamphetamine-related acute care hospital admissions. DESIGN ARIMA-intervention time-series analysis. SETTING California (1983-2000), Arizona and Nevada (1991-2000), USA. MEASUREMENTS Monthly counts of methamphetamine-related acute care hospit...
