[Research of the durability of connective tissue complexes formed in the implantation area of various types of allograft during the experiment].

The aim of the study is to examine in the experiment on the animals the mechanical properties of connective tissue complexes formed in alloplasty area using the intraperitoneal on lay mesh and sublay methodologies with further comparison of them. The experiment has been conducted on 12 rabbits of Russian chinchilla breed. Animals were distributed in the following way: the first group--operated by intraperitoneal on lay mesh methodology (n = 6) through implantation of composite grid Proceed with one-side celullose coating produced by "Ethicon" company. The second group--performed modeling of preperitoneal plastic using two-component composite grid with large-pores Ultrapro produced by "Ethicon" company (n = 6). For the tensometric evaluation of the strength of implant integration into the red wall was used entire area of anterior red wall together with the implanted transplant. According to the deflection diagrams and dynamometer rates defined the maximum burden rates which is equivalent of muscular tissue budge against polymeric matrix. Statistically significant distinctions during 14 days were not detected; however strength during 30 days in the first group was 3 times higher than in the second group. We consider that the methodology of intraperitoneal on lay mesh can be considered as operation of choice of surgery treatment of the umbilical hernias.

[Practical application of a high-frequency coagulators with different electrophysical characteristics].

The results of experimental-clinical investigation on studying of technical characteristics and practical application of various types of electrocoagulators were adduced. Comparative analysis of possibility to perform the main stages of surgical interventions, using well-known apparatuses of various manufacturers, was conducted.

[Classification of a high temperature methods for tissue dissection and achievement of hemostasis].

The results of experimental-clinical investigation, using apparatuses of a highly-temperature dissection and coagulation of a various type of action, were adduced. Classification of a highly-temperature dissection and coagulation in accordance to type of action and kind of the energy used was elaborated, basing on analysis of results of experimental operations and clinical application of apparatuses of various manufactures.

[Experimental investigations of coagulation possibilities of noncoherent optico-electronic systems in operations on parenchymatous organs].

Results of experimental investigation on elaboration and trial of surgical hemostasis method, using the quartz heating optic noncoherent irradiators of light, are adduced. Basing on analysis of the results obtained, the apparatus for photooptic coagulation was elaborated and trialed on experimental animals.
