Oxidative stress in the optic nerve and cortical visual area of steptozotocin-induced diabetic Wistar rats: Blockade with a selective bradykinin B1 receptor antagonist

The role of bradykinin B1 receptors on the oxidative stress as measured by the levels of Na+/K+ ATPase activity, malondialdehyde (MDA) and glutathione (GSH) in male Wistar rat optic nerve and visual cortex area 1 and 4weeks after STZ treatment was studied. Rats were divided into 4 groups (n=6 –7): 1. Controls (non-diabetics); 2. Diabetics (65mg/kg streptozotocin, STZ); 3. Diabetics injected with B1 antagonist R-954 (2mg/Kg) during the last 3days of a one week period; 4. Diabetics injected with B1 antagonist R-954 (2mg/Kg) during the last 3days of a 4week period.
