[Biochemical markers of early diagnosis of occupationally related arterial hypertension in workers of ore-dressing production].

The authors demonstrate that work conditions for main occupations of sylvinite ore-dressing production (drying machine operator, granulation operator, drying and granulation dosage department operator, centrifuge operator, filtration operator, transporting machine operator in drying and granulation department, mill operator) are characterized by combined exposure to chemical and physical occupational hazards: formaldehyde, highly dispersed dust (PM,0), industrial noise, increased microclimate parameters. The work conditions are considered as hazardous (class 3.1, 3.

[New potential of MTHFR gene variations application as an individual sensitivity marker in evaluation of occupational risk of arterial hypertension under exposure to nose].

The article deals with results of assessing risk of occupationally related hypertension among workers of sylvinitedressing works, with individual sensitivity consideration. Epidemiologic study proved correlation between occupational exposure to noise over 83 dB and hypertension and its predictors - increased activity of serum lipoprotein and homocystein. The studies determined an indicator of the workers' increased sensitivity to arterial hypertension development and to changes in parameters of disordered vascular tone regulation (increased activity of serum lipoprotein and homocystein) under exposure to noise - CT genotype of MTHFR gene.

Evaluation of health risk for workers engaged into processing of titanium-containing and rare-earth materials.

The authors defined occupational risk level and relations of health disorders in workers engaged into processing of titanium-containing and rare-elements materials with forecasting risk changes in accordance with length of service and its realization evaluation. Work conditions are characterized by exposure to chemicals (sulphur dioxide, nitrogen oxide, chlorine and hydrochloride, vanadium compounds), noise, general vibration, heating, work hardiness - and are evaluated as hazardous, jeopardy degree 3 and 4. Results of a priori assessment of occupational risk define it as high.
