statement of problem: patients affected with “early onset periodontitis” (eop), are not similar regarding their neutrophil deficiency and researches have yielded contradictory results in this field. purpose: the purpose of this study was to evaluate different aspects of neutrophils’ activities in peripheral blood of such patients, especially those affected with prepubertal periodontitis and juv...

Antioxidant activity of polar methanolic extract of aerial parts of Ocimum sanctum using multiple screens was studied. Various concentrations of the standardized extract were examined for the free radical scavenging activity, superoxide radical scavenging potential and effect on nitric oxide production in RAW 264.7 mouse monocytes cell line. The results indicated that the O. sanctum extract has...

We examined the hypothesis that oxygen radicals may mediate the vasodilator effect of VIP on cerebral arterioles in cats equipped with cranial windows. The appearance of superoxide anion radical in cerebral extracellular space during VIP application was examined by measuring the rate of superoxide dismutase (SOD)-inhibitable reduction of nitroblue tetrazolium (NBT). Although VIP (1 and 10 micro...

Synthetic superoxide dismutase mimetics have emerged as a potential novel class of drugs for the treatment of oxidative stress related diseases. Among these agents, metal complexes with macrocyclic ligands constitute an important group. In this work we synthesized five macrocyclic copper(II) complexes and evaluated their ability to scavenge the superoxide anions generated by the xanthine-xanthi...

The production of superoxide radicals (O2(-).) and the activities of ferricyanide reductase and cytochrome c reductase were investigated in peroxisomal membranes from pea (Pisum sativum L.) leaves using NADH and NADPH as electron donors. The generation of O2(-). by peroxisomal membranes was also assayed in native polyacrylamide gels using an in situ staining method with NitroBlue Tetrazolium (N...
