Abstract

In modern practical health care a large aspect is occupied by PRP-technology, the which effect is provided by growth factors located in alpha granules on the platelet membrane and responsible for the regeneration of connective tissue. The purpose of this study was a morphological assessment of reactive changes in periprosthetic tissue in PRP-technology application. Material and methods . The study was carried out on laboratory rabbits. Experimental animals were divided into two groups of observations - control and experimental. The endoprosthesis was implanted into the anterior region of the abdominal wall. Autoplasma enriched with platelets was injected after implantation under the endoprosthesis twice into experimental animals. A site with an endoprosthesis material was excised for a morphological study. Histological sections were stained with hematoxylin and eosin, according to Van Gieson, and Mallory methods, an immunohistochemical study was performed. The results of the morphometric study were processed using the Statistica v. 8.0. Results. In the experimental group the onset of the proliferative phase of inflammation occurred at an earlier time and provided the formation of a mature connective tissue periprosthetic capsule. By the 10th day of the experiment, a double dominance of the thickness of the capsule was observed in the experimental group. The proportion of cells of fibroblastic differon accounted for 60% of all cells, which resulted in an an increase in the cellular index by 1.6 times. The proliferation index was 2 times greater at all experimental days. Conclusion. The use of PRP-technology in endoprosthetics leads to an earlier formation of a mature periprosthetic capsule, accelerates the survival of the prosthesis and reduces the risk of postoperative complications.
