    The hematosalivary barrier selectively regulates metabolism, including trace elements between the blood and the internal contents of the salivary glands, provides a relatively constant composition of the physical, chemical and biological properties of mouth liquid. The aim was to study the content of elements (copper, zinc) in serum of blood and oral fluid of patients with oral lichen planus (OLP). The study involved only 95 patients: first group consisted of 19 people with the typical form of the OLP, second group -19 people with exudative-hyperemic form of OLP, third group consisted of 27 patients with erosive-ulcerative form, the reference group consisted of 30 healthy individuals. With increasing severity of the clinical course of the OLP (with exudative-hyperemic and erosive- ulcerative forms) function and the selective permeability of the hematosalivary barrier in respect of essential microelements - zinc and copper - are violated.ГСматосаливарный Π±Π°Ρ€ΡŒΠ΅Ρ€ ΠΈΠ·Π±ΠΈΡ€Π°Ρ‚Π΅Π»ΡŒΠ½ΠΎ Ρ€Π΅Π³ΡƒΠ»ΠΈΡ€ΡƒΠ΅Ρ‚ ΠΎΠ±ΠΌΠ΅Π½ вСщСств, Π² Ρ‚ΠΎΠΌ числС, ΠΈ микроэлСмСнтов ΠΌΠ΅ΠΆΠ΄Ρƒ ΠΊΡ€ΠΎΠ²ΡŒΡŽ ΠΈ Π²Π½ΡƒΡ‚Ρ€Π΅Π½Π½ΠΈΠΌ содСрТимым ΡΠ»ΡŽΠ½Π½Ρ‹Ρ… ΠΆΠ΅Π»Π΅Π·, обСспСчиваСт ΠΎΡ‚Π½ΠΎΡΠΈΡ‚Π΅Π»ΡŒΠ½ΡƒΡŽ Π½Π΅ΠΈΠ·ΠΌΠ΅Π½Π½ΠΎΡΡ‚ΡŒ состава физичСских, химичСских ΠΈ биологичСских свойств Ρ€ΠΎΡ‚ΠΎΠ²ΠΎΠΉ Тидкости.

    Considerations of occupational medicine concerning electrode production manufacturing

    Get PDF
    A number of harmful factors, namely carbon dust, sublimations of coal tars and pitches, benz(a)pyrene, noise, unfavorable microclimate conditions, are considered to be responsible for the occupational risk of workers dealing with electrode production manufacture. According to the document R 2.2.2006-05 the working conditions at the basic workplaces can be classified as the 3rd class of the 4th degree of hazard by the integral aerogeneous index with a presumption of the very high occupational risk (unacceptable) 1B category (according to R 2.2.1 766-03). It is proved by the high levels of the occupational morbidity being dozen of times higher than the similar average indexes in Russia (145.6 versus 1.7 events per 10,000 workers).ΠŸΡ€ΠΈ производствС элСктродной ΠΏΡ€ΠΎΠ΄ΡƒΠΊΡ†ΠΈΠΈ Π²Ρ€Π΅Π΄Π½Ρ‹ΠΌΠΈ производствСнными Ρ„Π°ΠΊΡ‚ΠΎΡ€Π°ΠΌΠΈ, ΠΎΠ±ΡƒΡΠ»Π°Π²Π»ΠΈΠ²Π°ΡŽΡ‰ΠΈΠΌΠΈ ΠΏΡ€ΠΎΡ„Π΅ΡΡΠΈΠΎΠ½Π°Π»ΡŒΠ½Ρ‹ΠΉ риск Π·Π΄ΠΎΡ€ΠΎΠ²ΡŒΡŽ Ρ€Π°Π±ΠΎΡ‚Π°ΡŽΡ‰ΠΈΡ…, ΡΠ²Π»ΡΡŽΡ‚ΡΡ углСродная ΠΏΡ‹Π»ΡŒ, Π²ΠΎΠ·Π³ΠΎΠ½Ρ‹ ΠΊΠ°ΠΌΠ΅Π½Π½ΠΎΡƒΠ³ΠΎΠ»ΡŒΠ½Ρ‹Ρ… смол ΠΈ ΠΏΠ΅ΠΊΠΎΠ², Π±Π΅Π½Π·(Π°) ΠΏΠΈΡ€Π΅Π½, ΡˆΡƒΠΌ, нСблагоприятныС микроклиматичСскиС условия.

    Item. 4.2.2.6 "bauxite pneumotoxicosis (influence of bauxite dust)" is included, in the "List of occupational diseases" (code Π₯ J 63.1), that requires elaboration of standards of its diagnostics, treatment and rehabilitation of patients. The article presents the results of clinicohygienic researches of the evaluation of influence of bauxite dust on the condition of bronchopulmonary system of the employees. It was shown than influence of low-fibrinogenous dust at the extraction of bauxite ore leads to the development of pneumotoxicosis, that shows itself as significant convection and. hemodynamic disorders that limit patients' earning capacity

    Ttie aim of our study was the investigation regional lung ventilation and pulmonary blood flow at the workers engaged in manufacture of crystalline silicon. It is established, that early signs of pulmonary ventilation disorders of lungs are reduce the local tidal volume in the lower zones of the lungs and changes in apical-basal gradient in the direction of increasing the ventilation of the upper bands of light relative to the lower levels.ЦСлью исслСдования явилось ΠΈΠ·ΡƒΡ‡Π΅Π½ΠΈΠ΅ Ρ€Π΅Π³ΠΈΠΎΠ½Π°Ρ€Π½Ρ‹Ρ… вСнтиляционных Π½Π°Ρ€ΡƒΡˆΠ΅Π½ΠΈΠΉ ΠΈ ΠΊΡ€ΠΎΠ²ΠΎΡ‚ΠΎΠΊΠ° Π»Π΅Π³ΠΊΠΈΡ… Ρƒ Ρ€Π°Π±ΠΎΡ‡ΠΈΡ…, занятых Π² производствС кристалличСского крСмния.

    Organism's responses to a long-term inhalation of silica-containing submicron particles of an industrial aerosol

    Full text link
    Female white rats were exposed during up to 6 months 5 times a week, 4 hr per day in a "nose only" inhalation device to an aerosol containing predominantly submicron (nanoscale included) particles of amorphous silica in the concentration 2.6Β±0.6 or 10.6Β±2.1 mg/m3. In an auxiliary experiment with a single-shot intratracheal instillation of these particles, it was shown that they induced a pulmonary cell response comparable with that to highly cytotoxic and fibrogenic standard quartz powder DQ12. However, in the long-term inhalation test, the studied aerosol proved to be of very low systemic toxicity and fibrogenicity. This paradox may be explained by low SiO2 retention in lungs and other organs due to a relatively high in vivo solubility of these nanoparticles. Nevertheless, their genotoxic action and transnasal penetration into the brain should make one give a cautious overall assessment of this aerosol as an occupational or environmental hazard.
