چکیده انگلیسی
We examined whether citicoline has neuroprotective effect on kainic acid (KA)-induced retinal damage. KA (6 nmol) was injected into the vitreous of rat eyes. Rats were injected intraperitoneally with citicoline (500 mg kgâ1, i.p.) twice (09:00 and 21:00) daily for 1, 3 and 7 days after KA-injection. The neuroprotective effects of citicoline were estimated by measuring the thickness of the various retinal layers. In addition, immunohistochemistry was conducted to elucidate the expression of choline acetyltransferase (ChAT) and tyrosine hydroxylase (TH). Morphometric analysis of retinal damage in KA-injected eyes showed a significant cell loss in the inner nuclear layer (INL) and inner plexiform layer (IPL) of the retinas at the 1, 3 and 7 days after KA injection, but not in the outer nuclear layers (ONL). At 1 and 3 days after citicoline treatment, no significant changes were detected in the retinal thickness and immunoreactivities of ChAT and TH. The immunoreactivities of ChAT and TH had almost disappeared in the retina after 7 days of KA injection. However, prolonged citicoline treatment for 7 days significantly attenuated the reduction of retinal thickness and immunoreactivities of ChAT and TH. The present study suggests that treatment with citicoline has neuroprotective effect on the retinal damage due to KA-induced neurotoxicity.
