Application of chrysanthemum rice extract in preparation of medicine for preventing and treating diabetic retinopathy

The invention provides application of a chrysanthemum rice extract in preparation of a medicine for preventing and treating diabetic retinopathy. By establishing a classic DM rat model, observing theinfluence of the chrysanthemum rice extract on blood glucose, weight and retinopathy of a DR rat and analyzing the change of CTGF expression level in retina of the DR rat, the result proves that the chrysanthemum rice extract can reduce the blood glucose level of the DR rat model and control the weight of the DR rat model to a certain extent, reduce dissolution and cell edema of retinal ganglion cells, relieve the condition that the thickness of a granular layer in retina is reduced, reduce the damage degree of retinal tissue of the DR rat to a certain extent and reduce the CTGF/Total proteinconcentration level of the DR rat, has a certain inhibiting effect on delaying the progress of retinal microvascular fibrosis of the diabetic rat, can be applied to clinical application as a medicinefor improving and treating
