Determination of free bile acids in pharmaceuticals by thin layer cromatography and high performance liquid chromatography
(Lubner Communication Srl, 1998)
High-performance liquid chromatography with evaporative light scattering detection (HPLC-ELSD) and thin layer chromatography with flame ionization detection (TLC-FID) have been applied to the separation of five main free ...
The influence of ethanol addition on excitation of aluminium in the argon stabilized d.c. arc
(Akademiai Kiado, Budapest, 1999)
The effect of ethanol addition on the spectral line intensities of aluminium and excitation conditions in an argon stabilized d.c. are was investigated. In order to find optimal conditions for trace elements determination, ...
Influence on a two-week disulfiram treatment on GGT and ALP activities in alcoholics
(Društvo medicinskih biohemičara Srbije i Crne Gore, Beograd i Univerzitet u Beogradu - Farmaceutski fakultet, Beograd, 1999)
Determination of gamma-glutamyltransferase (GGT) and alkaline phosphatase (ALP) activities are two of the most recently used biochemical parameters in diagnosis of alcoholism and heavy drinking. We examined the effect of ...
Influence of sodium dodecyl sulfate on the reaction between Nile Blue A and hydrogen peroxide
(Srpsko hemijsko društvo, Beograd, 1999)
The influence of the anionic surfactant sodium dodecyl sulfate on the rate of the reaction between the cationic form of Nile Blue A and hydrogen peroxide was investigated in the pH range from 5 to 8.5. A retardation of the ...
Quantity and composition of essential oil of the wild plant Nepeta nuda L. from Yugoslavia
(Journal of Essential Oil Research, 1998)
The aerial parts of the wild plant Nepeta nuda L. collected in Serbia and the Durmitor region contained respectively 0.67–0.70% and 0.4% oil. Each oil was analyzed by GC and GC/MS. The main constituent was 1,8-cineole; ...
New Tc-99m-diiodine substituted IDA derivative (DIIODIDA) for hepatobiliary imaging
(SpringerElsevier Science B. V., Amsterdam, 1999)
A new diiodine substituted LDA derivative, 2,4-diiodine-6-methyl IDA (DIIODIDA) was synthesized and labeled with Tc-99m. It was established that Tc-99m-DIIODIDA had high radiochemical purity. Biodistribution and influence ...
Effects of flavonoids on plasma coagulation tested in vitro by "screening tests"
(Društvo medicinskih biohemičara Srbije i Crne Gore, Beograd i Univerzitet u Beogradu - Farmaceutski fakultet, Beograd, 1999)
The effects of four flavonoids: rutin, quercetin, morin and hesperidin on plasma coagulation has been examined by measuring aPTT, TT and PT. It is found that water solution of these flavonoids shows no effects in the ...
The effects of selenium deficiency, dietary selenium, and vitamin E supplementation on the oxidative status of pig liver
(Begell House Inc., 1998)
The aim of this work was to determine the effect of Selenium (Se) deficiency on the porcine liver oxidative stability and to investigate Se content and oxidative status in porcine liver after dietary supplementation with ...
Kinetic Determination of Trace Levels of Selenium(IV) and Total Selenium by Nile Blue A/Hydrogen Peroxide Method
(Springer New York, 1998)
A kinetic method for the determination of selenium(IV) traces is proposed, based on its inhibitory action on the oxidation of Nile Blue A by hydrogen peroxide in phosphate buffer (pH 10.5). A linear dependence was established ...
Quantitative analysis of sulpiride and impurities of 2-aminomethyl-1-ethylpyrrolidine and methyl-5-sulphamoyl-2-methoxybenzoate in pharmaceuticals by high-performance thin-layer chromatography and scanning densitometry
(AOAC International, Gaithersburg, 1999)
A simple and reliable thin-layer chromatographic method for determining sulpiride and impurities of 2-aminomethyl-1-ethylpyrrolidine and methyl-5-sulphamoyl-2-methoxybenzoate was developed and validated. A methylene ...
