[Experimental substantiation of using gentacycol for prevention of wound infection in gunshot bone fractures of the extremities]. / Eksperimental'noe obosnovanie primeneniia gentatsikola dlia profilaktiki ranevoi infektsii pri ognestrel'nykh perelomakh kostei konechnoste'i.

There have been experimentally studied the antibacterial properties of the preparation "gentacycol" developed in the research institute of antibiotics. Its effective agent is gentamycin and as the matrix of a carrier modified collagen is used. It is indicated that in vitro and at implantation in preliminary infected ordinary and gunshot osseous wounds in rabbits and dogs gentacycol inhibits the growth of aerobic and, that is especially important, anaerobic microflora, limits the development of inflammatory Process and stimulates, to a certain extent, reparative osteogenesis. The obtained data allows to recommend gentacycol application for prophylaxis of wound infection in treatment of gunshot limb bone injuries.

[The biomechanical prerequisites and experimental validation of an arthroplastic method after the "rolling joint" principle]. / Biomekhanicheskie preposylki i éksperimental'noe obosnovanie metoda artroplastiki po printsipu "sustav kacheniia".

The authors have proposed the idea of joint motion realization by means of rolling of one joint surface over the other one. It allows to pass over an unsolved yet problem of cartilage restoration and normal gliding in the affected joint. It has been developed a model at the knee joint of a dog, which provides for resection of the joint surfaces according to semicylinder and plane shape and introduction of lavsane bands to hold and direct movement of the articular ends. 34 dogs have been subjected to experimental operations. There was achieved good and satisfactory joint and limb function with 25 of them. Biomechanical investigation allowed to prove joint mobility and limb supporting ability.
