Ketoconazole has been widely used as an antifungal drug that is formulated as tablets, cream and overthecounter ketoconazole shampoo. The aim of this research was to study and to standardize an ultraviolet spectrophotometric (UVS) method, potentiometric and a high performance liquid chromatographic (HPLC) method for the determination of ketoconazole in commercially available Oromycosal® tablets. These three methods were compared and discussed with respect to their sensitivity, selectivity and readyapplicability in routine analytical work. Absorption spectra and spectrophotometric determinations were carried out on the UVS spectrophotometer. Investigated concentrations were in range from 0.003 to 0.02mg?dm3. The absorbance was measured at 224 nm. In potentiometric titrations glass and saturated (KCl) calomel electrode were used. HPLC analyses of ketoconazole were carried in the presence of econazole as internal standard. It can be concluded that the described methods are simple, fast and reliable for determination of ketoconazole in pharmaceutical preparations. The preparation of the samples is easy, the excipients do not interfere in the methods, so they can be used in routine quality control analysis., Biljana Gjorgjeska, and Literatura
V krátkém sdělení podává autor informace o poznatcích z nedávných konferencí, zaměřených na problematiku koupání dětí v krytých bazénech. Postoje odborníků se dají shrnout do konstatování, že koupání kojenců a dětí je činnost, která vyžaduje dodržení zásad bezpečnosti provozu, aby nemohlo docházet k ohrožení zdraví, a provozovatelé těchto zařízení musí plnit všechny podmínky nutné pro poskytování služeb, včetně dostatečné výměny vzduchu. Nemohou obstát námitky, že jde o opatření investičně náročná. Přestože se zkušenosti s koupáním dětí v bazénech opírají o léta praktických i teoretických poznatků, existují stále otázky k dalšímu zkoumání., In the short communication the author submits the issues of recent conferences on baby swimming. Professionals mostly consider baby swimming as beneficial for the child's physical condition, but stress a strict observance of maintenance of the swimming pool. This must include also proper ventilation, regardless the costs which might be substantial. Although there is abundant experience with baby swimming, there still remain many problems to be researched., Ivan Černý, and Lit.: 7
