PHYSIOLOGICAL AND CYTOGENETICAL STUDY FOR EMPLOYEES AT HIGH VOLTAGE ELECTRIC STATIONS

Abstract

This research was conducted on 75 blood samples randomly selected from 25 persons directly exposed to electromagnetic field and 25 persons indirectly exposed in addition to 25 persons not exposed to that electromagnetic field(as a control group). The aim of this study is to know the effect of electromagnetic field (resulted from electric station) on some physiological blood parameters, and the genetic materials for workers at these electricity station .The physiological results indicated that there is a significant decrease in the hemoglobin concentration average at the probability P field as compared to control group; there was a decrease in the compact red blood cell volume average, in the total number of white blood cells and the percent of lymphocytes, monocytes and oesinophils, However there was a significant increase in the red blood cell sedimentation ratio and in the neutrophils and basophiles percents .Statistical results did not indicate any significant difference in the blood platelets ratio among the blood sample of the three various groups under study .The cytogenetic tests showed no chromosomal number changes within the samples of the three groups, but there was 14 qesses of structural chromosomal aberrations in the directly exposal group, seven of which as chromosome fragmentation ,one as chromosome deletion ,three as dicentric chromosomes, one as a centric chromosomes and two as ring chromosome as compared to four chromosomal fragmentation in the control group .There was decrease in the cell mitotic index in the persons how are directly exposed to the electromagnetic field while there was an increased effect on the lymphocytes with the advance of age and time exposure.In conclusion, the electromagnetic field has a direct and indirect effect on some physiological blood parameters and the genetic materials through the chromosomal aberration which case disease and deformation.
