title: [Chemiluminescence of the polymorphonuclear leukocytes-luminol system in the presence of biogenic chloramines].
abstract: It was demonstrated that N-chlorphenylalanine and other chloramines strengthen sharply chemiluminescence in the polymorphonuclear leukocytes (PML)-luminol system without special activation of cells. The intensity of chemiluminescence is higher than the intensity of luminol solution emission induced by N-chlorphenylalanine. But it was nearly equal to chemiluminescence intensity of a mixture of luminol, N-chlorphenylalanine and 20-30 nM H2O2. The increase in chemiluminescence in the PML-luminol system in the presence of N-chlorphenylalanine is not related to PML activation but is the result of direct oxidation of luminol by N-chlorphenylalanine. Chloramine derivatives of amino acids and taurine at final concentrations of 0.01-0.1 mM do not suppress luminol chemiluminescence in suspension of PML stimulated by phorbol-12-myristate-13-acetate. At the same time, hypochlorite inhibits sharply luminol emission induced by stimulated cells.
