CYTOCHEMICAL LYMPHOCYTIC MARKERS AS CRITE RIA IN MASS AND SELECTIVE HEMATOLOGICAL SCREENING FOR CHILDREN LIVING IN AREAS EXPOSED TO RADIOACTIVE CONTAMINATION

A cytochemical lymphocytogram by PAS-reaction and nonspecific esterase test was made using blood smears from 820 children living in differen t regions of the Bryansk area exposed to radioactive contamination and from 46 matched controls from noncontaminated territories. Most of th e children were born before the Chernobyl accident. The cytochemical l ymphocytogram was informative enough to evaluate lymphocytic pool and its renewal. The lymphocytoogram parameters criteria for selection of children's groups at relative risk. The groups comprised 25-60% of the examinees depending on the contamination degree and were registered f or subsequent follow-up and rehabilitation.
