THE POSSIBILITIES OF LASER DOPPLER FLOWMETRY IN THE DIAGNOSIS OF PREMORBID SKIN CHANGES OF WORKERS OF GAS-PROCESSING PRODUCTION

Aim. Improving diagnosis of premorbid skin changes of gas production employees.

Material and methods. 158 employees of male Astrakhan gas processing plant aged from 28 up to 59 years (on average 40,23±0,49 years) which didn't have at the time of survey the demonstrative forms of the somatic and neurologic diseases and 77 clinically healthy volunteers of control group who were constantly living to Astrakhan aged from 25 up to 55 years are examined (on average 38,18±0,99). Average length of service at the enterprise made 9,02±0,29 years. Assessment of a functional condition of a skin by method of laser Doppler flowmetry was carried out on the laser analyzer of a capillary blood flow (LAKK-01) (NPP Lazma, Moscow).

Results. The analysis of hemodynamic types of microcirculation showed that at gas processors disturbances of a peripheric circulation in a skin, and in superficial vessels more expressed, than in deep took place. Most often in all vessels of a skin of brushes and in deep layers of a skin of forearms the hyperemic type, mainly with blood stasis signs in capillaries and stagnation in a post-capillary link was registered.

Conclusion. Frequent registration of the phenomena of a stasis of a blood can demonstrate formation of a mikroangiopatiya almost at a third of employees of the plant under the influence of factors of production medium.
