Abstract des Autors
Leucocyte immunophenotypes were determined before and after a 100-km-ultramarathon run in 10 athletes by flow cytometry. Absolute cell numbers of leukocytes increased from 5750 +/- 600 (mean +/- SD) before the race to 16802 +/- 3050x10**6 cells/l 15 min after the race, mainly due to the neutrocytosis and monocytosis, whereas lymphocytes and eosinophils decreased. CD19+ B-lymphocytes remained at stable cell numbers (-5%), CD3-CD16/CD56+ (-65%), CD3+CD16/CD56+ (-53%) and CD3+CD8+CD45RO+ (-72%) lymphocytes decreased most. The latter three populations showed highest, the B-cells the lowest surface antigen density of LFA1. We conclude that adhesion molecules are likely to be important in the exercise induced redistribution of leucocytes. Verf.-Referat
