Radioimmunoassay of TNF?, IGF, and TGF? in proliferative vitreoretinopathy / 第三军医大学学报

ABSTRACT

Objective To measure the levels of tumor necrosis factor ? (TNF?), insulin like growth factor (IGF), and transforming growth factor ? (TGF?) in the pathogenesis of proliferative vitreoretinopathy (PVR), traumatic proliferative vitreoretinopathy (TPVR), and proliferative diabetic retinopathy (PDR). Methods The levels of TNF?, TGF?, and IGF in vitreous samples taken from 56 patients and 13 normal subjects were determined by radioimmunoassay (RIA). Results The levels of TNF? and IGF in vitreous samples from patients with PVR, TPVR, and PDR increased significantly, as compared with those of the normal controls ( P 0.05). Conclusion TNF? and IGF participate in the pathogenesis of PVR, TPVR, and PDR.
