Immunological Injury on the retina in streptozotocin-induced diabetic rats / 中华内分泌代谢杂志

The depositions of immunoglobulins on the retina of diabetic rat were studied with immunohistochemistry,immunofluorecence and computer analysing system.In comparison with control group, depositions of IgG,IgA and IgM on the retina of diabetic rat induced by streptozotocin were significantly increased (all P＜0.05 ).So the immunoglobulin depositions may contribute to the pathogenesis of diabetic retinopathy.

The role of complement activation in the pathogenesis of diabetic complications / 中华内分泌代谢杂志

Complement system is an important constituent in immune system.Membrane attack complex (C5b-9)is the final ingredient in the complement activation.Recently,a few studies showed that C5b-9 deposition was found in the diabetics with chronic complications,indicating that complement activation might be involved in the pathogenesis of diabetic complications.Our aim is to summarize some newly published works and show a prelimimary work we did in this area.We hope that more attention should be paid to the role of autoimmune mechanism in diabetic complications.
