The severity of complications and a large percentage of disability related to the occurrence cold injury lead to medical, social and economic problems. Considering the contact of cold injury as a variety of acute ischemia with the subsequent formation of early and late postischemic disorders as causes of disorders of blood circulation in the affected segments can be considered a disorder of the oxidant-antioxidant status and cytokine, systemic inflammation, reperfusion syndrome, the development of endothelial dysfunction, which ultimately leads to multiple organ failure. In the course of the study when assessing the microcirculatory changes caused by the simulation of frostbite, the most pronounced effect of the combined treatment of Serotonin adipinate 4.5 mg/kg and opioid peptide DSLET 10 μg/kg compared with monotherapy with the studied drugs was estimated. The most effective correction of indices of oxidant- antioxidant protection observed with the combination of necrectomy with a combination of Serotonin adipinate and opioid peptide DSLET, which was confirmed by approximating the indicators of malondialdehyde, superoxide dismutase, finite stable metabolites of nitrogen oxide, total antioxidant activity and catalase to the values of intact animals on the 14th day of the experiment and reducing the level of proinflammatory cytokines (interleukin-6, tumor necrosis factor-alpha) in 2 times (p < 0.05) compared to the Control group. The combined use of Serotonin adipinate 4.5 mg/kg and opioid peptide DSLET of 10 µg/kg in combination with active surgical tactics (necrectomy) helps reduce the severity and prevalence of alternative changes, accelerate the formation of granulation shaft, a more intense development of reparative processes in the simulation of cold injury compared with the monotherapy. The combined use of investigational drugs in combination with active surgical tactics led to the maximum enhancement of the survival of the animals with contact frostbite in the experiment.

стр.41-54
Lyashev Y.D., Serikov V. S.
The results of investigation illustrate the lipid peroxidation activation in different tissues under the stress influence. The obtained results convince the different resistance of animals to stress. The decrease of free and bound oxyprolin content, as well as glycosaminoglycans, which are the main components of connective tissue of gingiva, after prolonged stress has been established. Stress causes the development of structural and functional disorders in the liver tissue. Melatonin is effective to inhibit the stress-induced changes in liver and parodontium. The higher efficiency of melatonin at the dose 1,0 mg/kg over 0,2 mg/kg was established. The obtained results open the prospects of the using of melatonin and its artificial analogues for pharmacological treatment of stress-induced disorders in parodontium and liver.

CORRECTION OF ISCHEMIC DAMAGE TO THE RETINA ON APPLICATION OF PHARMACOLOGICAL PRECONDITIONING OF RECOMBINANT ERYTHROPOIETIN
стр.67-90
To study the protective properties of pharmacological preconditioning with recombinant erythropoietin suberitro stimulating dose of 50 IU / kg in the retina of the eye, was the model of retinal ischemia, ischemia with the assessment of the temporary simulation mode of the retina of rats with the instrumental methods of analysis and morphometric studies. The most suitable model was a model 30 minute ischemia with subsequent reperfusion periods of 1 hour to 72 hours. We studied the protective effect preconditioning suberitro stimulating recombinant erythropoietin in a dose of 50 IU/kg, preconditioning distant ischemic and emoxipine 2 mg/kg per rat model of retinal ischemia. In the experiment, it was revealed that the recombinant erythropoietin (50 IU/kg) prevents the development of degenerative retinal layers due to ischemic damage more than distant ischemic preconditioning and emoxipine. The observed protective effect of erythropoietin us with the development of ischemia was confirmed by laser Doppler flowmetry, electroretinography and morphometry. Using suberitro stimulating recombinant erythropoietin in a dose of 50 IU/kg, 30 minutes prior to the pathology simulation eliminates erythropoietic effect, and the lack of positive dynamics in groups with preliminary administration of glibenclamide 5 mg/kg, the key role of ATP-dependent potassium channels in a preconditioning mechanism implementation. Identification and use of pharmacological agents, which have the effect of preconditioning, may be a new approach in the correction and prevention of retinal ischemia, which is the leading element in the pathogenesis of a number of visual pathologies. The possibility of pharmacological preconditioning with erythropoietin ischemic lesions of the retina is essential for the development of anti-ischemic agents for the treatment and prevention of ocular pathologies of ischemic origin.

стр.91-98
Malorodova T.N., Pokrovskaya T.G., Kazakova E. E., Urojevskaya J. S.
Foot infections are a common and serious problem in persons with diabetes. Persistent ulcers in patients with diabetic foot syndrome in 85% of cases lead to amputation because of secondary infection and growing gangrene that significantly worsen the prognosis. The review provides the information on the spectrum of microorganisms, initiating the development of clinical and morphological forms of diabetic foot infections. Special attention has been paid to the choice in diabetic foot infections antibacterial medications based on indicators of sensitivity to them by allocated microorganisms and features of therapeutic concentrations formation in the skin, soft tissues or bone. Clinical data of researchers in the degree of penetration of various antibacterial agents in soft tissue and depend on severity lesions. In our review, it was shown that the most common pathogen was Staphylococcus aureus, followed by Pseudomonas aeruginosa, Enterobacteriaceae: E. coli, Proteus spp., Klebsiella pneumoniae, Enterobacter spp., and Acinetobacter spp. due to multidrug-resistant organisms, such as extended-spectrum beta- lactamase-producing Gram-negative rods or methicillin-resistant Staphylococcus aureus have emerged as substantial problem. Data on the frequency and the sensitivity of key pathogens in diabetic foot differ in Russian and foreign researchers, which causes the necessary treatment considering local peculiarities allocated pathogens and the degree of penetration of anti-infective agents in the affected tissues.

In this article research the influence of natural montmorillonite containing sorbent used as a mineral supplement in animal feed in an amount of 30 g per 1 kg of sorbent feed on commercial quality table eggs at his dacha hens-layers. Found that feeding hens’ mineral feed additive reduces the toxic chemical elements in a chicken egg. It was found that the weight of the eggs in the experimental group compared to the control group, was significantly increased by 3,5% (p <0,05) after the completion of feeding the mineral sorbent. Despite the fact that in the control group, egg weight did not change and remained virtually unchanged. There is a bright pigmentation and reduction of "marbling" of the egg shell in the experimental birds. Set reduction "marbling" of 4.9 % and a decrease in light-colored eggs by 48.3 %. It has been established that chicken’s experimental group had a higher feed consumption and conversion (1.4 kg) as compared to control birds (1.3 kg). The best feed conversion per unit of egg products was observed in the experimental birds due to increased productivity. Proved that the marketability of the eggs is in direct proportion to the consumption of laying hens’ natural montmorillonite containing sorbent. Found that despite the great variety of indicators that characterize the quality of table eggs, the main thing is the maximum permissible levels of pollutants in them. Concluded that when administered in feed for laying hens 3 wt. % Montmorillonite clay containing eggs canbe obtained with low dietary content of harmful substances entering the body to feed the birds .
