[Effect of pefloxacin on luminol-dependent chemiluminescence and leukocyte adhesion]

The in vitro action of pefloxacin on the luminole-dependent chemiluminescence and adherence of polymorphonuclear leukocytes of guinea pigs was studied within a wide range of the concentrations from 0.1 to 100 micrograms/ml. Pefloxacin did not influence the peak values of the chemiluminescence while in concentrations of 0.1 to 10 micrograms/ml it retarded its attenuation. After incubation of the leukocytes in the presence of 100 micrograms/ml of pefloxacin and the subsequent washing out the drug there was observed a decrease in the chemiluminescence. In concentrations of 0.1 to 100 micrograms/ml pefloxacin had no significant effect on the leukocyte adherence.
