Abstract:
ObjectiveTo determine the source of IL-6 in detached retina and the change of IL-6 level in detached and reattached retina.MethodsRetinas of SD rat were examined after subretinal injection of 1.4% Healon GV at different period of time, and the level of IL-6 in detached and reattached retina were detected by radio-immune histochemistry method. Wax-embeded sections were labeled with IL-6 antibody to determine the location of IL-6.ResultsDetached retina with normal vitreous and inner limiting membrane could only induce the subretinal fibrosis. This kind of fibrosis reached to its peak at 10th day and then remolded with time. Retinal pigment epithelial (RPE) cell, Muller cell, endothelial cell, glial cell were labled with IL-6, and the level of IL-6 in neuro-retina reached to its peak at 3rd-4th day and then downed to normal within a few days. The level of IL-6 in reattached retina was lower than in detached retina. The expression of IL-6 in RPE of detached area was stronger than in attached area.ConclusionIL-6 takes active part in wound healing process induced by the separation of RPE and neuro-retina. Reattachment can lower the expression of IL-6 in retina.
