Core Tip

Core Tip: To investigate the effects of glabridin and gymnemic acid on the choroidal layer and choriocapillaris in diabetic rats’ eyes, as well as the expression of vascular endothelial growth factor and cluster of differentiation 31. Five groups were created out of the Wistar rats. In the diabetic group, there was an increase in the thickness of both the choroid layer and the wall of the arteries as well as choroidal impairment. The choroidal thickness, and the walls of the choroid arteries in diabetic rats treated with glabridin 40 mg/kg body weight, the diabetic rats treated with gymnemic acid 400 mg/kg body weight, and the diabetic rats treated with glyburide 4 mg/kg body weight groups all rose. When compared to the group with diabetes, the expression of vascular endothelial growth factor and cluster of differentiation 31 was shown to be lower.
