摘要：Objective:The goal of this study was to see if travoprost and β-blockers improved MDA and SOD expression as well as neuroprotection in glaucoma mice.Methods:One hundred healthy SPF SD rats were randomly allocated into five groups:travoprost and β-blocker group,travoprost group,β-blocker group,model group and blank group,with 20 rats in each group.We created a glaucoma mouse model in which the blank group and the model group received the same volume of saline,the β-blocker group received β-blocker,the travoprost group received travoprost,and the travo Prost and β-blocker groups received travo Prost and β receptor blockers.Retinal cell apoptosis level,intraocular pressure level,MDA and SOD levels were measured after drug administration.Results:The results showed that the levels of intraocular pressure,the apoptosis rate of optic nerve,SOD and MDA of retina in travoprost and β-blocker group,travoprost group,β-blocker group and model group were greater than those in blank group(P<0.05).In comparison to the model group,the intraocular pressure level,optic nerve apoptosis rate,and retinal MDA level in the travoprost and β-blocker group continued to fall,while the retinal SOD level was considerably elevated(P<0.05).The continuous application of travoprost and β-blocker resulted in a constant drop in intraocular pressure,optic nerve apoptosis rate and MDA level in the retina,whereas the SOD level was dramatically elevated(P<0.05).Conclusion:In glaucoma mice,travoprost in combination with a β-blocker can greatly increase MDA expression,SOD and neuroprotection.
