[Generation of active forms of oxygen by human peripheral blood neutrophils and lymphocytes during adhesion to glass]

Oxygen activation by neutrophils and human blood lymphocytes at adhesion to glass have been studied by luminol--dependent chemiluminescence. It has been established that the cell interaction with glass leads to the formation of O2-., O2', .OH and H2O2. Chemiluminescence kinetics and the excited--oxygen forms ratio at adhesion were different for neutrophils and lymphocytes. The desorption of cells resulted in a decrease of the chemiluminescent response to neutrophils and lymphocytes when they again adhered to glass and in practically complete inhibition of chemiluminescence induced by adding concanavalin A. It has been determined that at adhesion of neutrophils and lymphocytes to glass different mechanisms of oxygen activation take place.
