title: Drugs effects on superoxide generation and chemiluminescence response of human leukocytes.
abstract: Luminol-enhanced chemiluminescence was used to determine the effects of diethyldithiocarbamate, dipyridamole, catechin and verapamil on the generation of reactive oxygen species in human leukocytes, and on superoxide generated by chemiluminescence of the hypoxanthine xanthine-oxidase reaction. These agents reduced the luminol enhanced chemiluminescence response of activated leukocytes, most probably by inhibiting the superoxide generation reaction. On the other hand, citrate and diethylcarbamazine, produced a slight increase of the luminol enhanced chemiluminescence of leukocytes.
