[Effects of the umbilical blood stem cells in experimental injury of myocardium].

Morphological, functional signs of myocardium affection and tolerance to physical loading in animals with isoproterenol-induced affection of myocardium after transplantation of a nuclear-containing cells (NCC) of umbilical blood were analyzed in comparison with a natural course of the model. There was proved, that a transplantation of a NCC promotes acceleration of processes of regeneration and restoration of the damaged myocardium in experimental animals. There were estimated the changes in localization of the transplanted NCC in the zone of damage, and capacity of the peripheral blood NCC, while they were transplanted, using intravenous injection, to migrate into the damage zone.

[Remote results of plastic operations on the tricuspid valve in patients with cardiac insufficiency at terminal stage].

Comparative analysis of the results of plastic operations performance on a tricuspid valve (TV) in patients, suffering cardiac insufficiency in terminal stage, was conducted. In late postoperative period the indices of intracardial hemodynamics (cardiac output fraction, regurgitation on TV) and clinical features (severity of symptoms, quality of life) after plastic operations, using a support ring, have differed significantly from those after performance of a sutured plasty. The valve function during five years was secured in 91.
