[INFLUENCE OF TITANIUM COATING ON THE BIOCOMPATIBILITY OF POLYPROPYLENE IMPLANTS].

Comparative analysis of the proliferative activity of inflammatory cells and distribution of collagen types I and III was carried out around the net materials of polypropylene and titanium coating polypropylene using im- munohistochemical method and polarization microscopy. Experimental modeling of implanted mesh material were made in the soft tissues of the lumbar region of rats. On the 7th postoperative day, quantitative analysis of proliferating cells delected using antibodies to the Ki-67 protein showed, a significant decrease (p < 0.

[Plastic closure of "difficult" duodenal stump with tamponade of ulcerous crater].

The method of plastic repair of the duodenal stump with an invaginated cone formed from the antral part of resected stomach was developed experimentally on 10 cadavers. Experimental surgeries on 16 mongrel dogs demonstrated primary healing and fast epithelisation of this duodenal stump. The method was used in 2 patients with giant penetrating ulcers of the posterior wall of the duodenum, promising results were seen.
