摘要
AIM:To investigate the effect ofβ-alanine(BA)on laserinduced choroidal neovascularization(CNV)mice models.METHODS:Laser-induced CNV mice models were established,and BA was administrated for one week and two weeks in advance,separately.Furthermore,retinal pigment epithelium(RPE)-choroid flat mounts were separated,and immunohistochemical staining was performed.The laser-induced CNV lesion areas were measured and compared.In addition,liver and kidney morphologies were observed to identify potential hepatorenal toxicity.RESULTS:Enlarged CNV lesion areas were observed in the BA treated group.No significant differences were observed in the liver and kidney sections between groups.CONCLUSION:BA treatment increase CNV lesion areas,suggesting the detrimental effects of BA as a nutritional supplement in age-related macular degeneration(AMD)population.
