Method for preparation and application of autological erythrocytes from umbilical blood for anemia correction in newborns

FIELD: medicine.

SUBSTANCE: method includes the following steps: umbilical cord samples collection, processing, placement for storage and rejection of samples, a pre-transfusion processing for umbilical blood samples. At the pretransfusion preparation stage, the erythrocyte mass from the plasma is separated by centrifugation at acceleration of 3768 g for 15 minutes at a temperature of +4°C. Then the auto-erythromass samples pass the procedure of auto-erythrocytes washing from the preservative and hemolyzed cells formed during umbilical cord sample storage. To do this, 100 ml of sterile physiological sodium chloride solution is added to the packet with auto-erythromass in the umbilical erythromass and physiological solution ratio of 1:1 and centrifuged at 1971 g acceleration for 10 minutes at a temperature of +4°. After this, the supernatant is removed using a plasma extractor. The washed umbilical erythrocytes are filtered through a microaggregate filter. All samples of autologous erythrocytes of umbilical blood pass quality control: the degree of hemolysis and quantitative indicators of blood cells, hemoglobin and hematocrit are determined.

EFFECT: invention allows to correct anemia in newborns by a single blood transfusion, without occurrence of posttransfusion complications associated with donor blood components transfusion.

SUBSTANCE: tissue-specific matrix is obtained by performing a perfusion washing and a decellularisation of a parenchymal organ. Herewith 60-120 minutes before the perfusion washing of the donor organ, measures to prevent intravascular blood cell aggregation and microcirculation disturbances are taken and involve the intramuscular or intravenous administration of a disaggregant or disaggregants (heparin and trental) into a donor. That is followed by an organ perfusion by administering into its vascular bed phosphate-buffered normal saline of the following composition: 138 mM NaCl, 2.67 mM KCl, 1.47 mM KH2PO4, 8.1 mM Na2HPO4, distilled water up to 1l and containing 1% serum albumin and 10-15% glycerol or 10-15% dimethyl sulphoxide with pH 7.4 in an amount equal to a double amount of the vascular bed of the organ at a perfusion pressure of 100-120 mm Hg in its arterial system. Thereafter, the decellularised organ is ground to a particle size of 0.5mm to 4mm; the ground fragments are portioned in an amount of 5-10g, and each portion is frozen by immersing into liquid nitrogen gas for 5-10 minutes. The frozen portions are re-ground to a particle size of no more than 600 mcm; then each portion is de-frozen by re-suspending in phosphate-buffered normal saline 30-70ml of the following composition containing 138 mM NaCl, 2.67 mM KCl, 1.47 mM KH2PO4, 8.1 mM Na2HPO4, distilled water up to 1l , with pH 7.4, at a room temperature. The prepared suspension is cleaned from the particles of less than 200mcm; the prepared fraction is lyophilised and sterilised to prepare the target matrix samples.

EFFECT: using the invention enables providing the more complete decellularisation procedure ensured by preventing the disturbed microcirculation in the donor organ, providing higher density and uniformity of the re-cellularisation of the entire matrix and easier control thereof by increasing the matrix adhesive surface areas for the contact to inoculating cells as prepared in the form of powder.
