To analyze cellular parameters, we used flow cytofluorometer COULTER EPICS XL by Beckman Coulter Inc. with statistical processing by Statistica 10 program with critical significance level p0.05. As compared to the healthy childrens parameters, the children with BA showed higher level of Th17, decreased absolute number of lymphocytes, B- and T-lymphocytes, with the increase in the share of Tlymphocytes with the early and late activation markers. The studies performed identifi ed in children with BA the changes in the pattern of lymphocyte subpopulations and functional activity of T-lymphocytes which determine the immune response imbalance, activation of antigen recognition regulation, triggering and realization of immune response, lymphocyte proliferation and differentiation.</p>immune competent cellsbronchial asthmachildrenиммунокомпетентные клеткибронхиальная астмадети[1.
