Abstract
Objective To observe the expression of HIF-1 and iNOS and VEGF following alkali burns in the rabbit cornea and find out the effection of AS2O3 on expression of Hi-land iNOS and VEGF. To study the mechanism of HIF-1 and iNOS inhibition of AS2O3 on the cornea neovascularization. Methods To induce the models of alkai burns in Japanese rabits. Rabbits were randomly divided into 4 groups. Different concentration of AS2O3 were used in the experimental group with subconjunctival injection. And the control group was subconjunctival injection with 0. 3ml 0. 9% of normal saline. CNV was observed everyday with slit lamp microscope after alkali burns 24 hours. To detected the expression of HIF-1 and iNOS and VEGF by immunohistochemical techniq. Results The neovascularization area of cornea and the expression of HIF-1 and iNOS and VEGF after alkali burn with AS2O3 were less than those of contrast( P <0. 05 );The difference was significant with the increasing of the dose of AS2O3. Conclusion AS2O3 can inhibit the cornea neovascularization after corneal burns; HIF-1 and iNOS are important angiogenic factors in the process of forming corneal neovascularization; The mechanism of AS2O3 inhibiting corneal neovascularization is probably associated with the inhibitive expression of HIF-1 and iNOS.关键词
