Effects of celecoxib and amniotic membrane suspension on neovascularization area and expression of MMP-2,mmp-9 in corneal thermal-burned rabbit
摘要
Abstract
Objective To compare the effects of celecoxib and amniotic membrane suspension (AMS) on corneal neovascularization (CNV) area and expression of matrix metalloproteinase-2 (MMP-2) and matrix metalloprotein-ase-9 (MMP-9) in the growth of corneal neovascularization after thermal burn in rabbits,and provide a theoretical basis of celecoxib for the clinical treatment of corneal neovascularization.Methods Left corneas of 36 rabbits were burned by the home-made burning-device,and randomly divided to three groups:negative control group (n =12),AMS group (n =12) and celecoxib group (n =12),were respectively sub-conjunctival injected by 90 g · L-1 saline (0.1 mL),AMS (0.1 mL) and 8 mg · mL-1 celecoxib solution (0.1 mL).The histological morphology,growth condition and area of CNV were compared under slit lamp microscope at 4 days,7 days and 14 days after thermal-burned.At 7 days after thermal-burned,four appropriate corneas were randomly taken to detect the expression of MMP-2 and MMP-9 by immunohistochemistry,and the results were analyzed by computer image analysis system.Results At 4 days,7 days,14 days after thermal-burned,the areas of neovascularization were (11.32 ± 1.11)mm2,(38.49 ± 4.64) mm2,(43.30 ± 4.39) mm2 in negative control group,(9.69 ± 1.30) mm2,(31.15 ± 4.85)mm2,(37.19 ± 5.27) mm2 in AMS group,(8.47 ± 1.20)mm2,(30.31 ± 4.93) mm2,(36.69 ± 3.54) mm2 in celecoxib group,respectively.At different time points,neovascularization area in AMS group or celecoxib group was significantly lower than negative control group (all P ＜ 0.05).There was no difference between AMS and celecoxib group (all P ＞ 0.05).At 7 days after thermal-burned,the expression of MMP-2 and MMP-9 was not different between AMS group and celecoxib group (all P ＞ 0.05),and significantly lower than negative control group (all P ＜ 0.05).Conclusion Celecoxib and amniotic membrane suspension can all effectively inhibit CNV after thermal-burned,which may be related to the down-regulated expression of MMP-2,MMP-9 in thermal-burned corneas.关键词
