    Opis:
    Sand and soil were experimentally contaminated with eggs of Ascaris suum and oncosphercs of Hymenolepis diminuta in three doses: 500, 3000 and 5000 eggs (oncospheres) per 50 g of the ground. Numbers of recovered eggs were compared with the use of the two following methods: the method of flotation and Spindler's method, modified by Vasilkova and Ivančuk. The ground samples were investigated the following day and on the 14th day after the contamination. The samples were stored in 20°C and in 4°C. The Spindler's modified method turned out to be better for the studies of outdoor samples, because it enabled us to detect eggs in slightly infected samples, and in different temperatures.

    Opis:
    At the first experiment 20 Swiss male mice were infected with 100 larvae and 20 mice with 500 larvae T. spiralis per mouse. Two days after infection (d.a.i.) mice orally received 1,5 mg Cd (water solution CdCl₂) each. 40 mice were infected only T. spiralis as conrol. At the second experiment muscle larvae used were isolated from mice (from the first experiment) which received Cd. 20 mice were infected with 100 larvae and 20 - with 500 larvae per mouse. Two d.a.i. mice received 1,5 mg Cd. Mice fom both experiments were killed at 5, 10, 20 and 42 d.a.i. Total number of adult T. spiralis worms present in the small intestine and muscle larvae were recovered by conventional technique. Results of the first experiment: the number of adult worms and muscle larvae recovered from mice received Cd. were statistically significant lower as in control. Results of the second experiment the mean number of adult worms in experimental group and in control were the same but the mean number of larvae per gram of mice muscle were significant higher as in control.

    Opis:
    The cooperation of scientists specializing in different fields has given rise to the integration of previously distinct thematic areas and creation of new multidimensional disciplines as a result. Biochemistry, which has derived from the borderline of chemistry and biology, can be set as a good example. In this short review an insight into electrochemical studies, which are currently carried out in the Department of Microbioanalytics at the Faculty of Chemistry (Warsaw University of Technology), was presented. Three independent scientific pathways introducing electrochemical methods for biochemical and bioanalytical purposes can be distinguished among the ongoing researches. The first one embraces the design of the so-called electronic tongue – a system used for the qualitative and quantitative analysis of liquid samples of complex composition. In this work, potentiometric sensor arrays were applied to develop an electronic tongue system enabling the evaluation of the effectiveness of bitter taste masking of pharmaceuticals. The second scientific pathway involves voltammetric studies of the interactions of biologically active peptides with copper(II) ions. The interest was drawn to clarify and describe the role of β-amyloid and NSFRY copper(II) complexes, relevant to Alzheimer’s disease occurrence and cardiovascular system disorder respectively. Finally, boronic acids and their derivatives, exhibiting the affinity for molecules possessing 1,2 or 1,3-diol group in their structure, were used as selective molecular receptors in the third research project. The studies include the selection of the optimal method and conditions of the immobilization process, providing the most favorable receptor layer structure, and the determination of the performances of constructed electrochemical sensor towards particular bioanalytes.
