Experimental research of protective effects of dimethylthiourea in the rabbit retina laser injury

Dimethylthriourea(DMTU) is an effective free radical scavenger.Through investigation of histopathological and biochemical changes,we have obseved the effects of DMTU on rabbit retina in laser injury.The results show that photoreceptor cells die mainly of apoptosis in laser-induced retina degeneration and DMTU demonstrate the neropotective effect due to inhibition of lipid peroxidation.
