Hybrids of cationic porphyrins with nanocarbons.

In the review hybrids of cationic porphyrins ( porphyrins functionalized by quaternary pyridinium groups) with nanocarbons such as fullerenes, carbon nanotubes and graphene are described. Selected examples of these species are characterized in regard of their properties and possible applications.

AM1 CI and ZINDO/S study of quaternary salts of diazaphenanthrenes with haloalkanes.

For quaternary salts of diazaphenanthrenes 1-3 with methyl iodide 4-6, diiodomethane 7-9 and 1,2-dibromoethane 10-12 UV spectral values have been calculated by AM1 CI, and in the case of 4-6 also with ZINDO/S method. Correlations of experimental and calculated wavenumber values of considered compounds show good compatibility. For geometry optimisation of 4-9 the AM1 CI method has been used.

[Peripheral blood phagocyte count and ultrastructure of neutrophils in patients with hyperthyroidism and hypothyroidism].

The study was carried out in 80 women with hyperthyroidism (40 with Graves-Basedow disease and 40 with hyperactive nodular goitre) and in 30 women with primary hypothyroidism. In the group with hyperthyroidism the total leucocyte count and the absolute count of neutrophils in peripheral blood were lower than in controls. In the group hypothyroidism the absolute count of monocytes was higher than in controls.

Ultrastructural aspects of the small intestinal lead toxicology. Part I: Surface ultrastructure of the small intestine mucosa in rats with lead acetate poisoning.

The effects of low concentration of lead acetate on the apical surface of the jejunal enterocytes were studied. Young male rats were divided into 2 groups which received 0.01% lead acetate solution in drinking water during 30 and 60 d respectively.
