[Morphogenetic problems of dilated cardiomyopathy].

A comprehensive histochemical, histoenzymatic, morphometric and ultrastructural evaluation of 27 autopsy and 22 biopsy specimens of the right ventricular endomyocardium, aimed at the study of dilatation cardiomyopathy, revealed alteration, compensatory and adaptation response in the cardiac muscle. The processes were recorded light-optically and ultrastructurally. Discussed are the mechanisms of the disease morphogenesis and ways of relevant therapeutic correction.

[Conservation of the lung in the course of 2 to 24 hours with delayed autotransplantation in the experiment].

Opportunities of preservation of the lung at +4 degrees C and in association of this temperature with hyperbaric oxygenation during 2 and 24 hours with postponed autotransplantation have been studied. In 74 experiments on dogs postponed autotransplantation of the lung was performed, including 46--with preservation during 2 hours, and 28--with preservation during 24 hours. Based on the studies carried out, it was found that in preservation of the lung during 2 hours at +4 degrees C or in association of +4 degrees C and hyperbaric oxygenation the lung could be successfully employed for postponed autotransplantation.
