Production of reactive oxygen species by neutrophils was analyzed by a chemiluminometric method in the presence of luminol in ten healthy donors, eight patients with gastric cancer and ten patients with gastric precancer. The neutrophil chemiluminominescence response to recombinant tumour necrosis factor (rTNF) was almost five times lower in the gastric patients when compared with healthy donors and precancer patients. The chemiluminescence response to zymosan was decreased only in the gastric cancer patients with chemiluminescence index activation (CTNF) less than 1. The observed changes of neutrophil functions are thought to result in a decrease of neutrophil cytotoxic activity in gastric cancer patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
