The application of capillary electrophoresis techniques in toxicological analysis.

Capillary electrophoresis (CE) comprises a group of techniques used to separate chemical mixtures. Analytical separation is based on different electrophoretic mobilities, thereby allowing qualitative and quantitative evaluations to be made. The application of CE in medical science, especially in toxicological studies, is developing rapidly because of the short time required for analysis and its high sensitivity, selectivity and ability to determine substances of an acidic, alkaline and neutral character.

[Use of 4 microbiological methods to detect Helicobacter pylori].

The presence of Helicobacter pylori (HPY) was confirmed in 90% of a group of 76 patients with gastric disorders. The methods included the direct urease test, a preparation directly stained by the Gram method, culture and serological study using Cobas Core Anti-H. pylori EIA.

[Presence of various Acinetobacter species in urinary tract infections].

Species classification of 39 strains of Acinetobacter isolated from urinary tract infections (UTI) was performed by API 20NE tests. On the whole 24 biotypes were differentiated which formed 4 species and one biotype had no defined species classification. Acinetobacter baumani was most numerously represented.
