| This study was conducted to evaluate the effect of extracts of Passiflora edulis Sims leaves on the oxidative metabolism of rat peritoneal neutrophils using a model of acute inflammation. The extract was obtained by maceration in 70% ethanol, evaporation under reduced pressure and lyophilisation. Total phenolic content (TP) was determined by the Folin-Ciocalteu assay. The P. edulis extract, in different doses, was administered by gavage 1 h prior to inflammation induction by carrageenan (8 mg/kg, i.p.); five hours later, the neutrophils were obtained by intraperitoneal lavage. The tests performed in neutrophils were cytochrome C and chemiluminescence assay as well as myeloperoxidase (MPO), superoxide dismutase (SOD), glutathione peroxidase (GPx) and... |
