Kinetic determination of microquantities of rutin by perturbation of the Bray-Liebhafsky oscillatory reaction in an open system
(Springer-Verlag Wien, Vienna, 2003)
A kinetic method is described for the microquantitative (microconcentration/microvolume) determination of rutin based on potentiometric monitoring of the concentration perturbations of the Bray-Liebhafsky (BL) oscillatory ...
First-order UV-derivative spectrophotometry in the analysis of omeprazole and pantoprazole sodium salt and corresponding impurities
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
The first-order UV-derivative spectrophotometry, applying zero-crossing method was developed for the determination of omeprazole (OM), omeprazole sulphone (OMS), pantoprazole sodium salt (PANa), and N-methylpantoprazole ...
Determination of bifonazole in creams containing methyl- and propyl p-hydroxybenzoate by derivative spectrophotometric method
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
A second order derivative spectrophotometric method for the determination of bifonazole in the presence of methyland propyl p-hydroxybenzoate as preservatives has been developed. The determination was performed in a 0.1 M ...
Thymopoiesis following chronic blockade of beta-adrenoceptors
(Informa Healthcare, London, 2003)
The present study was undertaken in order to further clarify putative role of the adrenergic innervation in the regulation of the intrathymic T-cell maturation. For this purpose adult male DA rats were subjected to either ...
Optimization of an RP-HPLC method for drug control analysis
(Marcel Dekker Inc, New York, 2003)
Optimization of important conditions for the reversed-phase high-performance liquid chromatographic method was done for the separation of the active ingredients in Marcaine(R) adrenaline injections (bupivacaine hydrochloride ...
Effects of beta-adrenoceptor blockade on the phenotypic characteristics of thymocytes and peripheral blood lymphocytes
(Taylor and Francis Ltd., 2003)
The study revealed that β-adrenoceptor blockade with propranolol (0. 40 mg/l00 g/day, s.c.) in adult male DA rats: (i) increased the thymocyte proliferation and apoptosis, (ii) caused disturbances in kinetics of T cell ...
Artificial neural networks in the modeling and optimization of aspirin extended release tablets with Eudragit L 100 as matrix substance
(AAPS PharmSci Editorial Office, 2003)
The purpose of the present study was to model the effects of the concentration of Eudragit L 100 and compression pressure as the most important process and formulation variables on the in vitro release profile of aspirin ...
Composition of essential oil of Artemisia campestris L. from Serbia
(Taylor & Francis Inc, Philadelphia, 2003)
The essential oil yield from the aerial parts of A. campestris was 0.2% (mL/g dried plant). The oil was analyzed using GC and GUMS and 38 compounds were identified. The principal components were sesquiterpene alcohols: ...
