Возрастная динамика показателей гемограммы и иммунного статуса У ДЕТЕЙ РАЗЛИЧНОГО ВОЗРАСТА

Abstract . General parameters of blood cells and immunity (including minor lymphocyte subpopulations) were determined in 196 healthy children from Chita City and 5 districts of the Chita Region, preceded by preselection of the subjects, using multi-step health evaluation schedules.When analyzing data on red blood cells, erythrocyte color index was found to become stable by the age of 3 years, followed by stabilization of blood hemoglobin content by the age of 7 years. RBC indices become stable at later ages..Basic leukocyte populations reach stability by 11 years, except for the numbers of neutrophilic granulocytes (by 15 years). All the T-cell subpopulations including the minor ones (NKT, HLA-DR+) continue to mature until 18 years, except for T-helpers, that become constant in their numbers after 7 years. Serum IgG levels stabilize by the age of 7 years; IgA and IgM amounts – by 18 years. (Med. Immunol., 2011, vol. 13, N 2-3, pp 261-266)
