RESUMEN
BACKGROUND: The article presents data on the state of cytokine regulation, indicators of endothelial damage when exposed to industrial vibration (general, local) and in combination with arterial hypertension. AIM: To improve the quality of early diagnosis and prevention of vibration disease in an isolated course and its combination with arterial hypertension based on a study of the cytokine profile, biomarkers of endothelial dysfunction in this pathology. MATERIALS AND METHODS: A comprehensive survey of 84 patients with isolated vibration disease from the effects of local, general, first, second degree and 61 patients with a combined course of vibration disease from the effects of local, general second degree vibration and arterial hypertension, 30 people in the control group without contact with industrial vibration and found healthy by medical examination. The levels of pro-inflammatory (IL-1, IL-8, TNF-) and anti-inflammatory cytokines (IL-4), biomarkers of endothelial damage (EDN-1, TGF-1, VEGF-A, PDGF-BB, fibronectin, Willebrand factor) were determined using the enzyme immunoassay method. RESULTS: The response of the immune system to the effects of industrial vibration is characterized by a cytokine imbalance an increase in the level of pro-inflammatory cytokines (IL-1, IL-8, TNF-) and a decrease in the level of anti-inflammatory cytokine (IL-4). With a combined course of vibratory disease and arterial hypertension, the cytokine imbalance is characterized by an even more significant increase in serum IL-1, IL-8, TNF- and a decrease in serum IL-4 concentration. Endothelial dysfunction with WB from the action of both local and general vibration in combination with hypertension is characterized by a significant increase in serum EDN-1, TGF-1, VEGF-A, PDGF-BB, fibronectin, Willebrand factor. CONCLUSION: The study of the cytokine profile, biomarkers of damage to the vascular endothelium in this pathology will allow for the early diagnosis of vascular disorders and to optimize preventive measures for workers in vibration-hazardous industries.

AIM: The study aimed at investigating the relationship between severe exacerbations of chronic obstructive pulmonary disease and hemorrhagic component of endobronchial inflammation. MATERIALS AND METHODS: Clinico-endoscopic characteristics of 118 patients presenting with severe infectious exacerbation of chronic obstructive pulmonary disease, bloody expectorations and endoscopically confirmed hemorrhagic component of endobronchial inflammation have been analyzed. All patients underwent a series (5-6) of bronchoscopic examinations accompanied by collection of bronchoalveolar lavage specimens to reveal the presence of acid-resistant mycobacteria and to determine the bacterial flora. The exclusion criteria were the concomitant pulmonary or extrapulmonary pathologic conditions which could lead to hemorrhagic endobronchial manifestations. The other direction of the study was to investigate a correlation between jugulation of the exacerbation and dynamics of such endobronchial symptoms as mucosal edema and hyperemia, quality of bronchial secretions and hemorrhagic component of endobronchial inflammation. RESULTS: All patients were found to have diffuse endobronchitis of severity grade II (39.83%) or III (60.17%) by Lemoine. The neoplastic and tuberculosis genesis of the hemorrhagic component of endobronchial inflammation and its clinical equivalent, the bloody expectorations, had been ruled out. In 50.85% of cases the hemorrhagic component of endobronchial inflammation could not be accounted for by hemolytic properties of cultured microorganisms. The mucosal edema and hyperemia remained stable during jugulation of the exacerbation. Unlike the improvement of quality of bronchial secretions, faster reversal of the hemorrhagic component of endobronchial inflammation showed statistical significance. CONCLUSION: The hemorrhagic component of endobronchial inflammation can represent a non-obligatory manifestation of severe exacerbation of chronic obstructive pulmonary disease, and its relief is the earliest endobronchial sign of incipient remission from severe COPD exacerbation.

The article analyzes the publications devoted to the problem of professional renal lesions caused by chemical factors. Classification, prevalence, peculiarities of the clinical picture, diagnosis of professional renal lesions caused by chemical factors of the production environment are reviewed. The frequency of professional renal lesions remains underestimated due to low manifestation of symptoms and the influence of environmental factors, which require further investigation of this issue.
RESUMEN
The article presents data of domestic and foreign authors on the relationship between occupational factors and arterial hypertension. The role of latent arterial hypertension, its frequency in the population, the lesion of the target organs and the prognosis in comparison with normotensive individuals, arterial hypertension of the "white coat" and stable arterial hypertension have been analyzed. Arterial hypertension in the workplace is a form of latent arterial hypertension. The authors review the influence of harmful production factors (physical, chemical), as well as psychosocial stress on the risk of developing arterial hypertension.The risk of developing hypertension in specified groups of workers has been analyzed separately. The place of production-related diseases in modern occupational pathology in the Russian Federation. A wider implementation of measures aimed at early diagnosis and prevention of arterial hypertension in workers is proposed.

On the basis of the conducted research, prevalence of tobacco smoking and its intensity are described as well as dependence on gender and age in an urban population of the middle Volga region (on the example of the city of Samara). It is proved, that in a general selection among men and women smoke: 49,37 and 14,17%; smoked before: 22,80 and 8,86%; never smoked: 27,83 and 76,97% of inspected men and women, accordingly. The contribution of the education level and marriage status are set in epidemiology of tobacco smoking dependence. Authors consider the development of public and medical measures in a fight against tobacco smoking should be realized, taking into account the gender, age, social and mental features of population, which is a difficult, but necessary process.

AIM: To examine prevalence and intensity of smoking among general population of Samara, physicians and students of Samara Medical University; to study dependence of this prevalence on different social factors. MATERIAL AND METHODS: A representative sample of adult population was selected by the lists of outpatients of Samara outpatient clinic. The study enrolled 2931 outpatients (1272 males, 1659 females aged 15 years and older)--3.95% of all Samara outpatients. The questionnaire survey covered 360 physicians aged 28-57 years (the response 96.5%), 652 senior medical students aged 21-24 years (the response 93.14%). The results were processed with the statistical computer program BIOSTAT. RESULTS: The percentage of smoking men among 15-19-year-olds was 42.94%, 20-29-year-olds--59.29% (p < 0.01), 30-39-year-olds--62.18%, 60-year-olds and older--35.64%. This proportion for smoking women was 15.04%, 27.11% (p < 0.01), 22.92%, 9.06% (p < 0.001), 5.04%, respectively. Among male physicians smokers were 47.37% (14.29% smoked less than 10 cigarettes, 50.79%--10-20 cigarettes, 34.92%--more than 20 cigarettes a day); 16.54% male physicians smoked earlier, 36.09% never smoked. Relevant percentage for female physicians was 25.99 (38.98, 47.46, 13.56, 13.66 and 60.35, respectively). Among male medical students smokers were 58.6% (29.2% less than 10 cigarettes a day, 55.8%--0-20, 14.9%--more than 20 cigarettes a day); 9.1% smoked earlier, 32.3% never smoked. Among female medical students smokers were 20.3% (70.9, 21.5, 7.6, 9.3 and 70.4%, respectively). CONCLUSION: Tobacco smoking depends on education and marital status. Both in men and women the least number of smokers are among persons with higher education and married ones.
