Purpose of the study. Investigation of harmful (contaminating) substances containing in the air pollution from enterprise on the production of cement in the case of partial replacement of the traditional fuel (coal) with the alternative fuel (RDF) from solid municipal waste.
Materials and methods of the study. Objects of the study: Scientific publications on questions of usage the alternative fuel from solid municipal waste in enterprises on the production of cement.
Results of chemical analysis of:
- the composition of the air pollution without the alternative fuel;
- the composition of the air pollution with the alternative fuel.
Work of the stove aggregates, including stove refrigerator, cyclonic heat-exchanger, system of serve of alternative fuel was under control.
Research methods. Methods of scientific hypothetical deductive cognition, sanitary-chemical methods, general logical methods and approaches of researches: analysis, synthesis, abstracting, generalization, induction.
Results. Partial replacement of the traditional fuel (coal) with the alternative fuel (RDF) from solid municipal waste caused decrease in consumption of gas burner fuel by 16%. The analysis of the received materials showed that the usage of the alternative fuel did not cause increase of the air pollution of the majority of contaminating substances. So СО concentrations decreased by 9,35%, SO2 from 2,0 mg/m3 to 0 mg/m3, СО2 were practically unchanged. Concentrations of nitrogen oxides were only slightly increased (by 4,2%). Sharp decrease in emissions of the polychlorinated dibenzo-p-dioxine and dibenzofurana took place, that reached on the top limit of emissions of 19 times (in kg/h) and on concentration – 20 times.
Conclusions. Stoves of enterprises on the production of cement do not need substantial reconstruction for the usage of the alternative fuel from solid municipal waste and they are effective for that. Production of alternative fuel (RDF) from SMW conduces to reduction of wastes and improvement of sanitary condition of grounds, dumps and depositories of solid municipal waste, that are substantial sources of environmental pollution.
Cement stoves are effective devices for utilization of solid municipal waste because the high temperature (1500-2000оC) of the working zone of stove and time of contact (7 sec) provide decomposition of toxic organic substances.
The analysis of the received materials enables to state that the usage of the alternative fuel did not cause increase of the air pollution of the majority of contaminating substances but cause their decrease in the air.
Key words: alternative fuel, solid municipal waste, traditional fuel (coal), technology of p, roduction of alternative fuel, dibenzo-p-dioxine and dibenzofurana, cement stoves, air pollution of harmful (contaminating) substances.

The purpose of the study – the formation of a system of criteria for the rehabilitation potential of the differentiated approach in making decisions by expert group about disability and disabled patients due to arteriosclerosis obliterans of the lower limbs.
Materials and Methods: We examined and analyzed the survey results of 1120 patients with obliterating atherosclerosis of the lower extremities, intended for inspection in the office of ITU in St. Petersburg. Were assessed the socio-demographic, clinical expertise, welfare, psychological and socio-environmental characteristics of the patients. Subjected to detailed analysis clinical and organizational aspects of rehabilitation, in particular: the disease, duration of the disease, early and regular conservative treatment, type of surgery and postoperative treatment in the presence of the stump - the period from the onset of a disease to amputation, etc. Using correlation and discriminative analysis were handled obtained qualitative and quantitative indicators. The strength of the functional connection with the correlation coefficient (h) <0,3 was assessed as weak, with 0,7 ≥ (h) ≥ 0,3 - moderate, (h)> 0,7 – strong. The reliability, the importance of the correlation coefficient was evaluated by the Student t-test.
Results: Was obtained reliable communication between different socio-hygienic, clinical expertise, medico-social and socio-environmental performance, contributing objectification of expert solutions in establishing different groups of disability in patients with atherosclerosis obliterans of the lower limbs. For the purpose of probabilistic forecasts primary amputation marked signs that are most significant effect on the outcome (disability), such as age, severity of labor, method of travel, duration of the disease, the presence of the stump, using a prosthesis, the time from the onset to amputation, ankle-brachial Index (LPI), the degree of chronic arterial insufficiency, concomitant diseases with complicated, the results of the initial examination. Consideration of received parameters allowed quite accurate (F-test = 73,789, Wilks' Lambda = 0,40179) and significantly (p<0.0001) to determine the probability of primary amputation among patients with atherosclerosis obliterans of the lower limbs, consideration of which is important in making decisions in the expert Bureau of ITU.
In order to improve cooperation between the departments of Health and medico-social expertise and improve the efficiency of their work they were formed and marked the important medical and social indicators affecting the expert decision in the exercise of examination of patients with obliterating atherosclerosis of the lower extremities.
Conclusion: For the purpose of objectification of expert solutions in the medical and social examination of sick and disabled, suffering from atherosclerosis obliterans of the lower limbs, should take into account the following important clinical expert indicators: age, socioeconomic status, occupation, the severity of the physical and the degree of intensity of mental work, the level of the prevalence of vascular process, severity of ischemia, the degree of limitation of movement at the time of the survey, co-morbidities and complications. Doctors of medical organizations while directing patients with obliterating atherosclerosis of the lower extremities for inspection in the office of the ITU and in the design of the corresponding clinics "Directions to the ITU," are absolutely necessary to consider not only the common clinical and functional parameters, but also the above-mentioned clinical and expert performance. This information should be written by physicians with the maximum fullness directing patients to ITU.
Received criteria of the likelihood of primary amputation among patients suffering from atherosclerosis obliterans of the lower limbs, are significant indicators of expertise, influencing the outcome of medical and social expertise.
In carrying out the study were highlighted indicators that allow us to estimate the level of rehabilitation potential, which in turn, causes the possibility of a differentiated approach when deciding on the disability group

North-Western State Medical University named after I.I. Mechnikov,
Introduction. Indentifying risk factors in patients with acute myocardial infarction is considered to be one of the most important diagnostic tasks, which ensures the selection of appropriate treatment approaches and decrease of adverse outcomes. ST depression in the left precordial leads in patients with lower myocardial infarctions can be regarded as a particularly significant factor, which indicates that such patients should be treated as high-risk at the stage of pre-hospital care.
Purpose. Assessment of the diagnostic potential of ST segment depressions in V4-V6 leads based on ECG and CAG data.
Materials and methods. The study included 31 patients with a lower myocardial infarction and an ST segment elevation. ECG and CFG diagnostic methods were applied.
Results and Discussion. 1. ST depression in V4-V6 segments in patients with lower myocardial infarctions is likely to indicate important stenoses in the LCA system (sensitivity 76%, specificity 80%);
2. ST depression in V4-V6 segments in patients with lower myocardial infarctions and an ST elevation are more likely to have a lowered ejection fraction (EF) than patients without ST depressions (r=0, 41);
3. ST depressions in V4-V6 segments in patients with lower myocardial infarctions and an ST elevation should be regarded as indicators of ischemia in the LCA area, which is not related to the myocardial infarction.
Conclusion. ST depression in left precordial leads in patients with lower myocardial infarctions and an ST elevation allows for treating such patients as high risk at the stage of prehospital care based on concurrent ischemia in the LCA area and the likelihood of heart failure.

Introduction. The problems of early diagnosis and prevention of occupational asthma (OA) are considered to be essential in reducing the number of occupational diseases.
Purpose. To determine the role of polymorphisms of interleukin 5 and the level of its expression in the development of occupational asthma.
Materials and methods. Genotyping and analyzing the level of expression was carried out with the help of specific oligonucleotide primers and DNA probes on a thermocycler with the real time detection of the results.
The study involved 105 patients diagnosed with OA who were hospitalized in the department of Occupational allergology and immunorehabilitation of "Ufa Institute of Occupational Medicine and Human Ecology". The control group consists of 354 non-relative individuals showing no symptoms of OA at the time of sample collection.
Results. There was a significant difference in the distribution of alleles and genotypes frequencies between the group of patients with OA and the healthy ones in the polymorphic locus rs2069812 of IL5 gene. It is shown that the presence of the T allele increases the expression level of IL5 gene almost by two fold. Increased serum levels of IL5 gene are responsible for many atopic and autoimmune diseases. It is shown that in patients with OA the IL5 gene expression level before treatment was increased almost by 3-fold.
Conclusion. The analysis of the frequency distribution of genotypes and interleukin 5 gene alleles has showed that the CC genotype (OR = 3,23; 95% CI 1,92-5,42) and C allele (OR = 2,07; 95% CI 1,52-2,8) of the polymorphic locus rs2069812 of IL5 gene were the markers of the occupational asthma increased risk.

Purpose: Algorithm construction for the infectious complications prognosticating of nosocomial pneumonia in severe acute neuroleptics poisoning based on the detection the following contents in the blood: the mediator of acute inflammation interleukin-6 (IL-6) and a marker of coagulation activation D-dimer.
Material and methods: There were examined 46 patients aged 42.6±6.2 years with severe acute poisoning by neuroleptics (clozapine). The content of interleukins 1β, 6, 8, 10, TNFα, and PCT were used as indicators of inflammation activity. The tests were performed at the time of admission and on the 1st, 3rd and 5th days after acute poisoning. Among the studied indices of nonspecific resistance in patients with severe acute poisoning with neuroleptics the levels of IL-6, IL-10, CRP, PCT and D-dimer in the blood were most consistently associated with the development of pneumonia (p<0.05) a y after the admission. Assessment of markers predictive value and the choice of the threshold values were peformed using ROC-curves in the first day.
Results: All patients observed demonstrated signs of systemic inflammatory response syndrome. The character of changes in investigated laboratory parameters and significant differences between them detected at 1st day after exposure to toxic, allowed the use of IL-6 and D-dimer concentrations for this day as early predictors of the pneumonia development in patients with acute neuroleptics poisoning.
Conclusion: Application of ROC-analysis revealed reliable laboratory criteria of nosocomial pneumonia development risk in patients with severe acute neuroleptic poisoning. These laboratory markers can be used as predictors of pneumonia development. The IL-6 and D-dimer concentration above 84 pg/ml and 1.31 mg/ml, respectively, indicates a high risk of nosocomial pneumonia developing in patients with severe acute neuroleptics poisoning. Such findings allow to begin
