title: [Influence of exam stress on the development of endothelial dysfunction and the formation of platelet-leukocyte coagregates].
abstract: The aim of this work was to study the qualitative and quantitative composition of circulating endotheliocytes, P-selectin-associated leukocyte and platelet of coogregation blood levels of endothelin, interleukin-6 students on the background of exam stress. The research was made on the group conditionally healthy volunteers aged MT 18.3 ± 1 years that before participating in the study had a medical examination (n = 15). Blood sampling was made three times: 1--three months before the session (in a normal school day, two hours after training sessions), 2--for 25 ± 10 min before the exam, 3 - 15 ± 10 min after the exam. Approved the development of endothelial dysfunction in the background of exam stress, manifested by increased levels of circulating endothelial cells and endothelin. The total number of leukocyte and platelet of coogregation during the semester, before and after the exam has not changed, while there was an increase outlets, due to the expression of P-selectin on red blood cells before the exam and precipitous decline after the exam.
