MORPHOMETRIC PARAMETERS AND PROPETIES OF ERYTHROCYTE MEMBRANE UNDER THE INFLUENCE OF EXTREME PROFESSIONAL FACTORS

240 hot papas (age 25-47 years) took part in the research. They were divided into three groups depending on the length of service: 1-6, 7-15, 16-25 years. Red blood cells parameters were examined by means of the blood analyzer "Micros-60 OT", membrane deformability and osmotic fragility were determined according to special techniques at the beginning and at the end of the daily shift. The morphometric parameters of hot papas' erythrocytes corresponded to normal values. The workload during the day did not lead to their significant shifts except anisocytosis in the group with work experience of 16-25 years. The influence of service duration on increase of red blood cell heterogeneity, a reduction in their total number and Hb level was found in the same group. At the beginning of the shift the membrane deformability and osmotic fragility in 0.45 % NaCl solution were significantly lower in all surveyed groups than in the control group. The average values of these parameters increased in all groups by end of the shift. However, the control group values were not achieved.
