چکیده

m We have su~ested a role for nitric oxide as a mediir of the autoimmune dcattuaion of tbe retina in our rat model of EAU. ln orevious immunohktochanical studies we detected the iNOS enzyme only dkng and at the site of active disease, c&xalising’tith activated ED1 positive macrophages intiltrating the retina. The ah of this study was to detect iNOS mRNA and investigate the eqreasion of intlammatory cytokines, knovm to be important In the hlducti0r1 of iNos in vifro, in diseased eyes throughout progression of EAU.

Effects of allopurinol and steroids on inflammation and oxidative tissue damage in experimental lens induced uveitis: a biochemical and morphological study.

AIMS To evaluate the effects of allopurinol in lens induced uveitis (LIU) by morphological methods and to compare these effects with those of steroids and a combination of both drugs biochemically and morphologically. METHODS Lipid peroxides (LPO) of the retinal tissue were determined by two different methods (thiobarbituric acid assay (TBA) and high performance liquid chromatography expresse...

Free radical scavenging and antioxidant activity of allopurinol and oxypurinol in experimental lens-induced uveitis.

PURPOSE In addition to the inhibition of xanthine oxidase, allopurinol is known to act, dependent on the dose, as a free radical scavenger, an antioxidant, and a "scavenger" of hypochlorous acid. This activity was investigated using a model of lens-induced uveitis. METHODS Lipid peroxides (LPO) were determined in aqueous humor and in retinal tissue. Reduced and oxidized glutathione (GSH and G...

Allopurinol has immunomodulating activity following topical and systemic application in experimental autoimmune uveitis.

PURPOSE Allopurinol has beneficial effects in the systemic treatment of lens-induced uveitis and experimental autoimmune uveitis (EAU). This is believed to be due to a reduction of oxidative tissue damage through its dose-dependent free radical scavenging ability, and to an immunomodulating effect. The purpose of this study was to demonstrate the immunological effects on the IgG-antibody repert...

Modulatory Effect of Pioglitazone on Sperm Parameters and Oxidative Stress, Apoptotic and Inflammatory Biomarkers in Testes of Streptozotocin-Induced Diabetic Rats

Background and Aims: Diabetes mellitus causes testicular damage by increasing oxidative stress and inflammation. In the present study, modulation of oxidative stress by pioglitazone, a synthetic ligand of peroxisome proliferator-activated receptor-γ, was examined in testis of streptozotocin-induced diabetic rats. Materials and Methods: Diabetes was induced by a single dose of streptozot...

Differences in the composition of inflammatory cell infiltrate in lens-induced uveitis under therapy with allopurinol or steroids.

PURPOSE The aim of this study was to compare the qualitative changes in the composition of inflammatory cell infiltrate in lens-induced uveitis (LIU) under treatment with allopurinol (Allo), methylprednisolone (Pred) or the two drugs combined (Allo/Pred). METHODS Twenty male Wistar rats were sensitized with lens proteins for eight weeks. Intravenous (IV) therapy was started after anterior cap...
