AIM To assess efficacy of reamberin in preoperative preparation and after coronary bypass (CB) in patients with macrofocal myocardial infarction (MI) complicated with postinfarction angina. MATERIAL AND METHODS A total of 45 patients with Q-positive MI complicated with postinfarction angina pectoris entered the trial. The study group consisted of 20(More)
A study was made of the effects of trypsin (0.25%) EDTA (0.02%), DMSO (10%) and suboptimal temperatures (16-18 degrees C) on the line L cells of monolayer and suspension cultures by the method of counter-current distribution in two-phase polymer system Dextran-500/poly (ethylene) glycol-6000. It has been shown that these agents cause the increase in number(More)
Distribution of cells (L929, LS, LSM) in the two-phase polymer system was studied in addition to characterization of their karyotypes. In the course of LSM cell passages, the increased ratio of cells with a reduced number of chromosomes was found. The results obtained show that in the process of adaptation of the suspension cell culture to the growth as(More)
The concept that stem cells form an independent subpopulations of somatic cells assumes the heterogeneity of cellular populations in adult tissues. As skin keratinocytes have natural affinity to extracellular matrix proteins, we made an attempt to reveal subpopulations of these cells depending on the time of their adhesion to substrates of collagen I and IV(More)
Limited knowledge about behaviour of stem cells in culture seems to be one of the reasons for problems in their successful introduction to applied medicine. To address this issue we have studied in vitro interaction of human mesenchymal stromal cells (MSCs) with various substrates (plastic, type I collagen, fibronectin, and mixtures of these proteins at(More)
The distribution of two sulines of L cells, differing in adhesive properties (monolayer and suspension cultures), have been investigated using polymer two-phase system dextran-500-polyenthylenglycol-600. By counter-current distribution it has been shown that most of the cells growing in monolayer have low coefficients of partition, unlike cells grown in(More)
A modified method of investigation of surface properties of cells and proteins with the help of a two-phase polymer system dextran-500/polyethylenglycol-6000 was used. This method is based on changing the kinetics of two-phase system partitioning into phase on adding cells or macromolecules. These changes were registered by measuring the top phase optical(More)
The morphometric characteristics of NCTC cells upon their contact with type I collagen added to culture medium were studied. The cells were plated on plastic in the colony form. In a day after seeding, the culture medium was changed for the same medium complemented with 0.1% type I collagen. And the cells were incubated in this medium for 30 min more. Then(More)
