СHANGES IN PARAMETERS OF LUMINOL-DEPENDENT AND LUCIGENIN-DEPENDENT CHEMILUMINESCENCE OF PERIPHERAL BLOOD NEUTROPHILS IN PATIENTS WITH BLADDER CANCER IN THE DISEASE DYNAMICS

Abstract

The study deals with parameters of luminol-dependent and lucigenin-dependent chemiluminescence (CL) of peripheral blood neutrophils from patients with bladder cancer (BC) prior to surgical treatment. We examined sixty patients (45 to 55 years old) with advanced bladder cancer (TNM) prior to the operation, and forty-six patients at 10 days after surgical treatment. A control group consisted of 56 healthy donors. Luminol-dependent and lucigenin-dependent chemiluminescence of blood neutrophils was assessed according to De Sole et al. (1983). Chemiluminescence assays of peripheral blood neutrophils from the patients with bladder cancer revealed changes in production of reactive oxygen species (ROS), both for initial stage of oxidation reaction, and total level of active oxygen radicals. We have found disturbed values of primary-to-secondary ROS ratio in the cells. In the patients with bladder cancer, some changes in oxidative metabolism of the blood neutrophils have been registered. These alterations may play an important role in promotion of potential effector cell functions, thus, probably, affecting the whole-scale development of a cytopathic effect exerted by neutrophilic granulocytes.
