[DNA, proteins and lipids distribution in the cells of olfactory bulbs of rats of various ages].

Using luminescent and absorption stains, specific for DNA (acridine orange, ethidium bromide), proteins (silver nitrate) and lipids (sudan III), the distribution of these substances was studied in the sections of rat olfactory bulbs, fixed by paraformaldehyde. DNA prevalence was found in glomerular cell layer as compared with the mitral one. Large amount of DNA was detected in granular cell layer, underlying the mitral one. The peculiarities of cellular layers of olfactory bulbs of 2-day-old rats were compared with those ones in 1-month-old animals. In rats of different ages, the differences were found in DNA content and distribution between layers, while no differences were detected in total protein and lipids. In 2-day-old rats glomerular underdevelopment was demonstrated.

[The effect of Wobenzym on the atherogenic potential and inflammatory factors at the rehabilitation stage for patients who have had a myocardial infarct]. / Vliianie vobenzima na aterogennyi potentsial i vospalitel'nye faktory na étape reabilitatsii bol'nykh, perenesshikh infarkt miokarda.

Effects were studied of wobenzyme on atherogenicity of blood serum and immunoinflammatory reactions in patients with myocardial infarction during the rehabilitation stage over six months. The basis therapy when supplemented with wobenzyme was found out to facilitate normalization of the atherogenic potential and to have a positive action on the mediators of the inflammatory process.

[Migration of fibroblasts into heart valve leaflet tissue in vitro]. / Izuchenie migratsii fibroblastov v tkan' stvorok klapanov serdtsa in vitro.

Heart valve allografts are widely used for surgical treatment of the heart. In recent years a new field of research has emerged dealing with allograft modification by cells of recipient by means of tissue engineering. This method involves culturing fibroblasts and endothelial cells, using recipient tissue, followed by introduction of the fibroblasts into tissues of allograft and coating its surface by the endothelial cells. This modification is expected to ensure the structural maintenance of implanted tissues and to reduce its thrombogenecity. This procedure may promote the allograft adhering to the recipient tissues, thus prolonging the terms of the valve normal functioning after implantations. For this purpose, methods of luminescent microscopy are suggested using double staining of tissue with fluorescent dyes Hoechst 33,342 and ethidium bromide, or with fluorescein diacetate and ethidium bromide. Experimental results are presented indicative of fibroblast migration from the surface to the human heart valve leaflets.
