Third-order derivative UV spectrophotometry and densitometry for the simultaneous assay of acetylsalicylic acid and salicylic acid in tablet formulations
(Societa Chimica Italiana, 1995)
Third-order derivative spectrophotometry is proposed for simultaneous determination of acetylsalicylic acid and free salicylic acid in sustained-release tablets, and compared with TLC-densitometry. Both methods were evaluated ...
Dependence of the Renal Excretion of Theophylline on its Plasma Concentrations and Urine Flow Rate in Asthmatic Children
(Journal of Pharmacy and Pharmacology, 1990)
Abstract— The dependence of the renal excretion of theophylline on its plasma concentration and urine flow rate has been investigated in asthmatic children of either sex. One group (age 12.25 ± 0.80, mean ± s.d. n = 8) was ...
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), ...
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 ...
HPLC method for determination of oximes HI-6 and trimedoxime in plasma / HPLC metoda za odredivanje oksima hi-6 i trimedoksima u plazmi
(Jugoslovenska medicinska biohemija, 1995)
A high-performance liquid chromatographic (HPLC) assay was developed to determine HI-6 and trimedoxime concentrations in small volumes of plasma. The HPLC system comprised a high-pressure pump (model 2150), a multiwavelenght ...
Effect of selected direct compression excipients on the stability of acetylsalicylic acid tablets
(Editio Cantor Verlag GmbH, 1995)
The effect of some direct compression excipients (Avicel® PH 101 (I), Avicel PH 101 + mannitol (II), Avicel PH 112 (III), Cellactose® (IV), and Pharmatose® DCL 40 (V)) under different storage conditions (22, 43 and 73% ...
HPTLC in the quantitative assay of drugs
(Springer Hungarica Kiado Kft, Budapest, 1996)
A simple, fast and reliable procedure for the determination of some drugs in commercial formulations (tablets, injections, suppositories, and oral suspensions is presented. After separation, quantitation,vas performed by ...
