...Fumiaki Yamamoto; Kano Hiroi; Yoshihito Honda We examined the effects of the antioxidant enzymes, 10,000 U/kg of superoxide dismutase (SOD) and 50,000 U/kg of catalase (CAT) on cat electroretinograms during the reperfusion after retinal ischemia. The intravenous administrations of SOD and CAT...

.... The antioxidative enzymes catalase and superoxide dismutase minimized damage to the RPE cells caused by LHP in proportion to the enzyme concentration. However, RPE cells incubated with LA were more affected by the enzymes than when no enzymes were added. 3 07 1995 5 10 1995 11 12 2009 © 1996 S...

...Yoshiji Ohta; Takashi Yamasaki; Takafumi Niwa; Katsuhiko Niimi; Yoshinao Majima; Isao Ishiguro The role of catalase in the retinal antioxidant defence system was examined in rabbits, guinea pigs, and rats with and without prolonged administration of a diet containing 0.4% 3-aminotriazole (3...

...O. Lewden; C. Garcher; C. Morales; A. Javouhey; L. Rochette; A.M. Bron Catalase activity was evaluated in Long Evans rat retina after ischemia and reperfusion. Ischemia was induced by ligation of the optic nerve and vessels. Rats were sacrificed after 15 and 120 min of reperfusion, respectively...

...A.P. Costarides; M.V. Riley; K. Green The effects of inhibition of both glutathione synthesis and of glutathione reductase and catalase activities have been determined in the regulation of hydrogen peroxide (H 2 O 2 ) in the anterior chamber of pigmented rabbits. Glutathione reductase inhibition...

...Michael A. Mancini; Nalin J. Unakar; Frank J. Giblin; John R. Reddan The diaminobenzidine (DAB) technique was used to investigate the localization of the peroxidatic activity of catalase in cultured lens epithelial cells at the ultrastructural level. Cultured rabbit, bovine and mouse lens...

... of the same strain fed on a special diet containing 0.2% amizol. Clinical picture of amizol cataract has been fully described. The decrease in catalase activity of lens capsule-epithelium is highest as compared to that of the corneal epithelium, liver, kidney, and blood in amizol-fed rabbits. Induction...

.... In order to study the role of oxygen radicals in experimentally induced phacoanaphylactic endophthalmitis, rats were immunized with soluble bovine lens protein and, following surgical disruption of the anterior lens capsule, subjected to treatment with catalase. Our data show that phacoanaphylactic...

Experimental lens-induced uveitis was produced in Lewis rats by sensitization with bovine lens protein prior to disruption of the lens capsule. Treatment of these animals by intraperitoneal injection of dimethyl sulfoxide...

Photoperoxidation could be thwarted by superoxide dismutase, catalase, and ascorbate, suggesting that the observed peroxidative degradation is initiated by photocatalytic generation of superoxide and its subsequent derivation to other potent...
