Abstract

PURPOSE
To investigate the neuroprotective effect of Ginexin (Ginkgo biloba extract) on rat retinal ganglion cell in the optic nerve crush injury model. METHODS: From 1 week before the optic nerve injury, Ginexin 100 mg/kg/day (100 mg group), 200 mg/kg/day (200 mg group) or carboxymethylcellulose as a control group (CMC group) was administrated orally 4 weeks in Spraque-Dawley rats. At 3 weeks after the optic nerve injury, the RGCs were counted and the concentration of intravitreal glutamate was measured. RESULTS: The RGC density of CMC group (103+/-22 cells/mm2) was significantly lower than that of 100 mg group (182+/-39 cells/mm2) and 200 mg group (201+/-63 cells/mm2). There was no difference between the 100 mg group and 200 mg group. The concentration of invtravitreal glutamate did not significantly differ among normal, CMC group, 100 mg group and 200 mg group. CONCLUSIONS: Ginexin increased the survival of the retinal ganglion cell in rat optic nerve crush injury model, but, did not influence on the concentration of intravitreal glutamate.
