 note = {Although it's known that complement regulatory proteins, which protect self-cells from activation of the complement, spread widely in a living body, we haven't had any reports about the existence of them in the human iris yet. In this study, we used an Immunofluorescence technique and investigated the expression of C3bC4b receptor (CR1), membrane cofactor protein (MCP) and decay accelerating factor (DAF), which inhibit activation of C3, and homologous restriction factor 20 (HRF20), which inhibits activation of C9, in irises from 7 patients with Behcet's disease and 7 patients with glaucoma but without uveitis as controls. CR1, MCP and DAF weren't observed in any patients. HRF20 was expressed on endothelial cells of vessels, iris stroma and iris pigment epithelium in all patients. Comparing the patients and the controls, revealed no significant differences. From these results, we propose as for activation of the complement system in the human iris, acceleration of vascular permeability and chemotactic activity of polymorphonuclear leucocytes, which are caused by activation of C3, occur easily and that cytolysis, which is caused by activation of C9, hardly occurs. We also propose the result that the less existence of complement regulatory proteins in the patients concerns the pathogenesis of the disease.},
