Experimental substantiation and clinical use of a combination of dermal matrix with allogenic or autologous cells for the treatment of extensive traumatic wounds.

We carried out a comparative experimental and clinical study of the efficiency of the combination of dermal matrix with autologous and allogenic cells for creation of an optimal biological wound coating. Experiments on outbred mice have demonstrated that the use of dermal matrix in combination with allogeneic or autologous cells shortens the inflammation phase and accelerated maturation of the granulation tissue. Clinical application of biological wound dressing based on dermal matrix in combination with autologous or allogeneic mesenchymal multipotent stromal cells prevented septic complications and shortened the time of preparing extensive traumatic wounds with skin defect to autodermoplasty.

Morphofunctional analysis of human platelets by vital staining.

We developed a method for differential staining of human platelets preserving their functional activity based on vital fl uorochrome stains trypafl avin and acridine orange. Platelets stained with trypafl avin and acridine orange exhibited under a fl uorescent microscope green fl uorescence of the cytoplasm and red-orange fl uorescence of the granules. Morphofunctional analysis of platelets was carried out on the cells from donor blood, donor concentrated platelets, and cells from hematological patients and patients with thromboembolic complications.

[Coagulation profiles during cardiac surgery].

Objective: To evaluate patients' hemostasis after cardiac surgery using thromboelastometric and impedance aggregometry.

Materials And Methods: 66 patients were examined intraoperatively. Comparison group included 45 blood donors.

[The morphologic evaluation of adhesive activity].

The morphologic evaluation of adhesive activity of human thrombocytes using both vital dye of cells and registration of adhesion process with fluorescent microscope is proposed. The regression dependence between adhesive activity of human thrombocytes and morpho-functional and aggregative activity of thrombocytes is established. The blood samples of 100 blood donors, 100 patients with hematologic pathology, 110 patients of traumatology, 50 patients with acute exogenous intoxications and 20 patients with chronic trophic ulcers were analyzed.
