Opis:: Articular cartilage is a highly organized avascular tissue, a matrix consisting of a three-dimensional meshwork of type II collagen fibrils and proteoglycans. To understand the effects of the alteration in chondrocyte shape in response to physiological load in local mechanical properties and, thus, to contribute to experimental load studies, we studied variation of the natural load induced deformations in chondrocytes among five different regions from bovine articular cartilage samples using confocal laser scanning microscopy imaging methods. The morphological differences of the chondrocyte shape, orientation and circularity in articular cartilage were measured. The chondrocytes were observed to be smoother in more loaded regions to the center of the cartilage.

Opis:: This work describes FT-IR studies results on adsorption of Cu(II) metal cation. Adsorption has been performed on 3A, 4A, 5A, AW-300, ammonium Y zeolite, organophilic, and molecular sieve zeolites using aqueous solution of the metal studied. Changes in intensities and positions of the pseudolattice bands corresponding to ring vibrations have been observed in the measured spectra. These changes are expected particularly in the pseudolattice bands connected with the presence of alumino- and silicooxygen tetrahedral rings in the zeolite structure. Also, Cu(II) adsorbed zeolites were each tested for their ability to catalyse the disproportionation of hydrogen peroxide in the presence of the added base imidazole. The Cu(II) adsorbed zeolites display efficiency in the disproportion reactions of hydrogen peroxide, producing water and dioxygen.

Opis:: Hydrogen peroxide is an ubiquitous metabolite in living systems, produced at increased levels in a variety of pathological situations. Therefore suppressing or at least controlling $H_2O_2$ production is important. Catalase enzymes can convert hydrogen peroxide into water and dioxygen and a similar role can be played by transition metal ions or some radiopharmaceuticals. (1) $TcO_4^-$, (2) Tc-99m mercaptoacetyltriglycine (MAG3) and (3) Tc-99m methoxyisobutylisonitrile (MIBI) were each tested for their ability to catalyse the disproportionation of hydrogen peroxide in the presence of the added base imidazole. It was found that (2) and (3) exhibit acceptable catalase-like activity compared to the Tc-99m pertechnetate.
