Spectrophotometric determination of some theophylline derivatives
(Acta Pharmaceutica Jugoslavica, 1988)
A spectrophotometric method for the determination of 8-chlorotheophylline, diprophylline and oxyethyltheophylline, is presented. Spectrophotometric determinations were carried out in CH3OH, 0.5 mol dm-3 H2SO4 4.65 mol dm-3 ...
The comparison of the spectrodensitometric determination of theophylline to HPLC, RIA and EMIT procedures
(Acta Pharmaceutica Jugoslavica, 1986)
Coulometric determination of methimazole

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 ...
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 ...
Spectrophotometric and potentiometric determination of acidic constants of oxo-phenyl pyridinium monoxime and dioxime
(Springer-Verlag, 1988)
The UV absorption spectra of 1-(1-hydroxyimino-2-oxo-2-phenyl) pyridinium chloride (compound I) and 1-(1-hydroxyimino-2-oxo-2-phenyl)-4-hydroxyiminomethyl pyridinium chloride (compound II) in water solution at different ...
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 ...
Reduction and Determination of 1‐[2‐Phenyl‐2‐(hydroxyimino)‐ethyl]‐6‐methylquinolinium Chloride on the Dropping Mercury Electrode
(Archiv der Pharmazie, 1987)
The polarographic behavior of 1‐[2‐phenyl‐2‐(hydroxyimino)ethyl]‐6‐methylquinolinium chloride has been investigated. The pH of the Britton‐Robinson buffer, used as supporting electrolyte, influences the position of the ...
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′ ...
Spectrophotometric behaviour of quinolinium oxime-palladium(II) complexes
(Springer-Verlag, 1985)
It has been established that 1-(2-phenyl-2-hydroxyiminoethyl)-1-quinolinium chloride, 1-(2-phenyl-2-hydroxyiminoethyl)-1-isoqui-nolinium chloride, 1-(2-phenyl-2-hydroxyiminoethyl)-1-(4′-methyl)-quinolinium chloride and ...
