摘要

Serum concentration of platelet-derived growth factor was measured in patients with trophic ulcers and proliferative activity of human fibroblasts was measured in wells with different content of added serum platelet-derived growth factor. In parallel, morphofunctional analysis of platelets from the whole blood of these patients was performed. A close correlation was found between morphofunctional parameters of blood platelets and serum concentration of plateletderived growth factor. Platelet-derived growth factor in concentrations below 150 pg per well stimulated fibroblast proliferation and preserved their viability. Platelet-derived growth factor in concentrations >200 pg per well suppressed fibroblast proliferation and impaired their viability.
