Musina L.A., Nuraeva A.B. BURN WOUND HEALING WHEN USING ALLOGENIC BIOMATERIALS (EXPERIMENTAL STUDY) [№ 12 ' 2015] Prevention of eyelid cicatricial deformity secondary to trauma or burn is the unmet need in ophthalmosurgery. In order to understand the mechanisms of tissue regeneration after eyelid surgical repair using allogenic biomaterials it is interesting to compare burn wound healing process without treatment, using conventional medications (Actovegin) and with the use of allogenic biomaterials in experiment. In the experiment was conducted on 84šwhite Wistar male-rats. Heat injury was modeled. In control group without treatment the healing process was accompanied by prolonged eschar presence, late epithelisation and slowdown of newly formed connective tissue maturation due to marked inflammation process. Reparation was incomplete and accompanied by coarse scarring. In the second control group treated with Actovegin the epithelisation was faster, nevertheless slowdown of reparation process in dermal layer was noticed. Inflammatory processes prevailed over reparative ones, granulation tissue stayed immature for a long time and eventually underwent scarring. In treatment group where animals underwent subcutaneous injection of disperse biomaterials (made from derma and tendon) rapid proliferation of epithelium was noted as long as necrotic mass demarcation and fast eschar desquamation. As granulation tissue matured it formed proper connective tissue plate of skin. It was found that the use of allogenic biomaterials in skin burns accelerated epithelisation and leaded to complete defect closure. Biomaterials inhibit coarse scarring during healing process.
Shangina O.R., Musina L.A. ELASTIC-DEFORMATIVE PROPERTIES OF COMBINED ALLOGRAFTS FOR THE RESTORATION OF THE ORBITAL WALLS [№ 12 ' 2015] The necessity of studying biomechanical properties of allografts stems from the inquiries of practical medicine. Problems of restoration surgery, transplantology and other sciences are solved based on the study of strength and deformative properties of tissues. The aim of physico-mechanical investigations is the evaluation of allograft as the material which temporary or constantly performs mechanical functions following the transplantation. Different methods of manufacture, preservation, lyophilization and sterilization of allografts lead, on frequent occasions, to the changes of biomechanical properties. The conservation of elastic-deformative properties of allografts during the process of their manufacture is an important factor which sets conditions for the effect of their clinical practice. Biomechanical tests were carried out in the tissue bank of the Russian Eye and Plastic Surgery Centre to evaluate strength properties of combined allografts manufactured according to Alloplant technology for the restoration of orbital walls. Combined allografts were modeled from the derma of the foot supporting areas and then were reinforced by the costal cartilage. The carried out tests showed the following resultsš— the parameters of relative elongation, ultimate strength and Young's modulus of elasticity of derma allografts didn't subject to reliable changes (compared with the control groupš— native derma). It allows to make a conclusion that mechanical properties of the given allografts are preserved after the physico-chemical treatment. Ultimate strength and plastic deformation parameters of the allografts reinforced by the costal cartilage treated as per Alloplant technology didn't undergo considerable changes as well, compared with the control group (native derma). It is established that multistage physico-chemical treatment as per Alloplant technology does not have an adverse effect on the strength characteristics of the derma of the foot supporting areas and costal cartilage which are used to manufacture a combined allograft for the restoration of the orbital walls. Such strength properties of allografts as tension and deformation, which in their turn, are of the utmost significance play an important part in reconstructive surgeries.

USE OF PLANT TEST SYSTEMS TO ASSESS THE TOXICITY OF BOTTOM SEDIMENTS [№ 10 ' 2015] This article is devoted to research the variability of heavy metals (Cu, Zn, Fe, Cd, Pb, Co, Ni, Mn) in sediments of r. Belaja on the territory of the Republic of Bashkortostan of Beloretsk district. The study of metals in their average content in the sediment form the following decreasing number of elements: Fe>Mn> Zn> Ni> Cu>Pb> Co> Cd. The concentration of Cu, Zn, Cd, Fe, Ni, Co in the sediments of the river exceeded the value of background: Óopperš— in the 6–15štimes, zincš— in the 13–20štimes, cadmiumš— in the 10–13štimes, nickelš— in the 1.5štimes, ironš— in the 9–11štimes, cobaltš— in the 155–185štimes, leadš— in the 1.6štimes. The concentration of manganese in all soils studied watercourse was within the geochemical background. Total index of contamination ranged from 201 to 243. The evaluation of the toxicity of the river sediments were determined by bioassay using the seeds of Lepidium sativumšL., Raphanus sativusšL., Triticum aestivumšL. Learned test systems according to the degree of sensitivity can be arranged in the following decreasing series: Lepidium sativumšL.š> Raphanus sativusšL.š> Triticum aestivumšL. The greatest sensitivity to contamination had such a test responses as seed germination and seedling root length. In this paper, the connection between the content of heavy metals in bottom sediments exceeding the geochemical background, and a manifestation of the properties of the indicator: increase in the concentration of copper and nickel inhibits seed germination, root length, and seedling dry weight of the plant model. The use of these plant test systems allowed to conclude that the studied soils of r.šBelaja are moderately toxic pollution degree, except for the alignment after the confluence r. Tirlyan characterized by narrow riverbed and, as a consequence, increase the speed of its flow with a predominance of the processes leaching of toxic elements from the sediments.

SCIENTIFIC-TECHNICAL PROGRESS AND SCIENTIFIC-ENGINEERING PROBLEMS OF INDUSTRIAL SAFETY [№ 9 ' 2015] It is shown that to ensure the safety and viability of the planet's growing population requires not only a constant increase in resources, but also to avoid the risks associated with the use of scientific and technological progress. Start of civilized management of hazardous industrial processes and facilities in the country was initiated adoption of the Federal Law №š116-FL of 21.07.1997 (12.21.2014), where the main requirements for industrial safety. For example of the Orenburg gas complex, the possible risks at hazardous production facilities at the impact of natural character illustrated. Industrial safety as an area of scientific activity is regarded. The basic stages of its development and improvement, including mathematical methods and computer technology risk prediction, identification of the causes of disasters, the development of new diagnostic tools and technical methods to assess the mechanics of deformation and fracture.

Kashin V.V., Musin D.Z. RICHARD RORTY: CRITISISM OF PHILOSOPHY AS A REPRESENTATION [№ 7 ' 2012] In the 20th century a number of attempts were done to lead a "reconstruction" of the history of philosophy to modern realities. One of these attempts was made by a famous American philosopher, representative of neopragmatism, Virginia University professor Richard Rorty. His "reconstruction" was to substitute epistemology by literary criticism.
Kashin V.V., Musin D.Z. CHARLES PEIRCE ON REPRESENTING FUNCTION OF THE SIGN [№ 7 ' 2010] Pragmatism relies upon "prescription" and availability of its objects in primary source, as well as upon separation of knowledge object and subject. Transparency or unshadiness from the point of view of reference of relations between subject and object and serves as one of the grounds for possibility of undistorted presentation of reality. Knowledge results "truth test" is performed by means of returning to this "prescription" with the help of relevant methods. Pragmatism assumes that though cogitation is based on presentation, "nothing stands" between consciousness and object: constantly improved methods allow to correlate representation and presentation through relations "truthš— false".
