This article aims to share the results of research conducted in the Fergana chemical plant of furan compounds (FCPFC) in Uzbekistan.19 workers of the Furan compounds plant, in Fergana, Uzbekistan, were tested. By neutron activation analysis method, we have studied microelement composition of saliva, blood, dental hard tissue, and the level of Ca, Zn, Fe, and Ag in these subjects. We have detected that the level of chemical elements in dental hard tissue, blood, and saliva of these workers was subject to negative changes as compared to the analysis results from those in the control group. The research results have practical value for the prophylaxis, treatment, and health resumption of the people living in rugged ecological environment and workers who are engaged with harmful substances in chemical industry. Furthermore,this research also provides recommendations for treatment of dental diseases related to common conditions of pathophysiological processes carried out by living organisms., Sunnatillo Gaffarov, Salim Sharipov, and Literatura
V letech 1991 až 2009 bylo v České republice ohlášeno 1 038 případů profesních nádorových onemocnění. Dlouhodobý trend byl sestupný, v 95 % byli postiženi muži. Střední věk při zjištění diagnózy zhoubného novotvaru byl 67 let. Převažoval profesní zhoubný novotvar průdušek a plic před difúzním mezoteliomem pleury a peritonea, následovaly nádory močového měchýře a kůže. Jako příčina zhoubných novotvarů dominovalo ionizující záření, 77 % osob postižených profesními nádory pracovalo při těžbě nebo úpravě uranové rudy. Autoři se zabývají zásadami diagnostiky i příčinami malého počtu uznaných nádorových onemocnění za nemoci z povolání. Autoři upozorňují, že seznam nemocí z povolání byl od července 2011 rozšířen o další zhoubné novotvary a je i širší možnost je uznat za profesní novotvary, které jsou způsobeny chemickými karcinogeny., The authors have undertaken the analysis of all cases of occupational malignant neoplasmas which were reported in the National Register of Occupational Diseases in the Czech Republic. In the years 1991–2009, 1038 occupationally-related tumour diseases have been notified. The trend was decreasing, males were affected in 95 %. The mean age of persons at diagnosing malignant neoplasma was 67 years. The occupational malignant neoplasm of bronchi and lunge prevaleid, followed by the diffuse mesothelioma of pleura or peritoneum, neoplasms of an urinary bladder and skin. Ionizing radiation dominated as the cause of malignant tumours in 77 % affected persons worked at mining and manufacturing uranium ore. The authors deal with current review attitudes and opinions of experts on principles of diagnostics of occupational malignant tumours. In the conclusions the authors analyze the cause of decreasing tendency in the number of notified occupational diseases. They inform which new malignant neoplasmas are included in the List of occupational diseases, and can be accepted as occupational diseases from 1 July 2011., Petr Brhel, Zdeňka Fenclová, Markéta Petrovová, and Lit.: 32
