Densitometric determination of conjugated oestrogens in the raw material and in pharmaceutical preparations
(Journal of Pharmaceutical and Biomedical Analysis, 1990)
A densitometric method for determination of complex mixtures of conjugated oestrogens in raw material and tablets was developed. The proposed procedure comprised hydrolysis of sodium sulphate esters of oestrone, equilin, ...
Use of pralidoxime-Pd(II) complex for the spectrophotometric determination of the cholinesterase reactivator (PAM-2Cl) in the urine
(Clinica Chimica Acta, 1990)
A simple and rapid method for the spectrophotometric determination of pralidoxime chloride in urine, based on complex formation with palladium(II) without preliminary mineralization of the sample, is described. The proposed ...
A study of several red cell enzyme markers in the Rumanian ethnic group in Yugoslavia.
(Gene geography : a computerized bulletin on human gene frequencies, 1990)
The present investigation reports the polymorphism of eight red cell enzymes, studied in 308 unrelated voluntary blood donors from the Rumanian ethnic group of Yugoslavia. Only common phenotypes were detected, which are ...
Red cell enzyme polymorphisms of the Hungarian ethnic group in Yugoslavia.
(Gene geography : a computerized bulletin on human gene frequencies, 1990)
A genetic study was carried out on phenotype and gene frequencies of the genetic markers in eight red cell enzymes: glyoxalase I (GLO1), glutamic pyruvate transaminase (GPT), phosphoglucomutase (PGM1), esterase D (ESD), ...
Relaxant component in the response of the guinea-pig mesenteric artery to histamine mediated by the release of the endothelium derived relaxing factor
(European Journal of Pharmacology, 1990)
Determination of triamcinolone, triamcinolone acetonide and fluocinonide in dosage forms.
(Acta Poloniae Pharmaceutica - Drug Research, 1990)
The colorimetric method for determination of triamcinolone, triamcinolone acetonide and fluocinonide in tablets, ointments and cream using isonicotinic acid hydrazide is proposed. This method provides a precise and ...
Potentiometric investigation of the stability of palladium(II) complex of pralidoxime chloride in aqueous solution
(Journal of Pharmaceutical and Biomedical Analysis, 1990)
The formation of a complex between palladium(II) chloride and pralidoxime chloride (PAM-2Cl) has been studied by means of potentiometric pH measurements. The real stability constant of the complex in aqueous medium of ionic ...
Spectrophotometric investigation of complex formation of an oxime PAM-4Cl with palladium(II) and its analytical application
(Journal of Pharmaceutical and Biomedical Analysis, 1990)
The colour reaction of 4-hydroxyiminomethyl-1-methylpyridinium chloride (PAM-4Cl) and palladium(II) chloride has been investigated. The optimum reaction conditions, spectral characteristics, conditional stability constant ...
Potentiometric and volumetric determination of 6-mercaptopurine
(Springer-Verlag, 1990)
Three methods for the determination of 6-mercaptopurine in the pure state and in tablets are described. One method is based on the reaction of this compound with silver ions, whereby an equivalent amount of nitric acid is ...
