Background: It is possible that oxidative stress causes several retinal diseases. However, the natural biogenic role of antioxidants in the retina is not clear.

Purpose: This study investigates the change in concentration of vitamin E (VE), ascorbate and glutathione (GSH) in the retina following vitreous injection of 600 mug 18:2 linoleic acid hydroperoxide (LHP) in male New Zealand rabbits.

Purpose: To study the effect of Sairei-to (ST), a Japanese traditional medicine, on oxygen-induced retinopathy (OIR) in rats.

Methods: OIR was induced by maintaining Sprague-Dawley neonatal rats in 80% oxygen for 12 days. The rats were treated once daily with oral administration of 0.

Purpose: We identified the temporal expression of activator protein-1 (AP-1) and matrix metalloproteinases (MMPs) after linoleic acid hydroperoxide (LHP) induction of retinal neovascularization.

Methods: After injection of LHP into the vitreous of rabbits, samples were collected for AP-1 binding activity and mRNA for MMP-9 and MMPs activity. AP-1 binding activity was measured by electrophoretic mobility shift assay.
