[Efficiency of assessment of retinol, alpha-tocopherol and beta-carotene by the liquid chromatography method].

Benign prostatic hyperplasia is very frequent disease of the primogenital system of elderly men. As the investigations show the antioxidant vitamins have various influence on the men's organism. They participate in the pathogenesis of many diseases.

[New photoreactive cleavable reagents with (trifluoromethyl)diazirine group].

Photoreactive cross-linking reagents that simultaneously contain a trifluoromethyldiazirine and an o-nitrobenzyl groups were synthesized for the first time. Photochemical properties of the reagents were studied, and the possibility of separate activation of the diazirine group and o-nitrobenzyl linker was shown.

[Impact of high-energy laser irradiation on pulmonic fibroblast in human embryo].

This impact was attained by medicinal laser application to alexandrite, dye, erbium and gallium arsenid in various conditions on cultures of pulmonic fibroblasts of human embryo. Obtained results were estimated by transmission and scanning microscopy. The highest cell destruction was observed in dye and alexandrite, being less expressed in gallium arsenid under laser irradiation.
