Spectrophotometric assay of xanthine oxidase with 2,2'-azino-di(3-ethylbenzthiazoline-6-sulphonate) (ABTS) as chromogen
(Clinica Chimica Acta, 1987)
A new method for the determination of xanthine oxidase activity, based on the oxidation of 2, 2'-azino-di(3-ethylbenzthiazoline-6-sulphonate) (ABTS) by use of uricase and peroxidase, is described. The absorbance increase ...
Determination of acidic constants of some phenyl-hydroxyiminoethyl quinolinium compounds
(Springer-Verlag, 1986)
Mixed acidic constants (pK′a) of quinolinium oximes [1-(2-phenyl-2-hydroxyiminoethyl)-1-quinolinium chloride (F-1), 1-(2-phenyl-2-hydroxyiminoethyl)-1-isoquinolinium chloride (F-2), 1-(2-phenyl-2-hydroxyiminoethyl)-1-(4′ ...
Pharmacokinetic evaluation of a sustained release preparation of theophylline in asthmatic children and adults
(Informa Healthcare, 1988)
A sustained release preparation of theophylline (SRP of Th) was evaluated pharmacokinetically in asthmatic children and adults and it was found to have good SR properties. Different dosage requirements for equal pharmacokinetic ...
Use of palladium(II) chloride as colour-forming reagent in determination of pralidoxime chloride in water and tablets
(Journal of Pharmaceutical and Biomedical Analysis, 1988)
Pralidoxime chloride (PAM-2Cl) has been determined spectrophotometrically in Britton-Robinson buffer solution at pH = 6.45; the method is based on measurement of the absorbance of the Pd(II)-pralidoxime complex at 327 nm. ...
The possibility of measuring the salivary concentrations of theophylline in bioavailability studies
(Informa Healthcare, 1988)
The possibility of using the saliva in bioavailability studies of theophylline was investigated. Plasma and saliva concentrations were determined simultaneously and corresponding pharmacokinetic parameters were calculated ...
Eight red cell enzymes polymorphisms in the Slovakian ethnic group of Yugoslavia.
(Gene geography : a computerized bulletin on human gene frequencies, 1988)
The polymorphisms of eight red cell enzymes were studied in 211 unrelated voluntary blood donors from the ethnic group of Slovakians (Yugoslavia). Only common phenotypes were detected, which are usually present in European ...
Endothelium-dependent relaxations to histamine in the rat common carotid, renal and cranial mesenteric artery
(Informa Healthcare, 1988)
The effect of histamine on the isolated rat common carotid, renal and cranial mesenteric arteries was examined. Histamine (10-8 - 10-4 m) caused concentration-dependent relaxations of the arteries during contractions induced ...
