Objective:Establishment and evaluation of type 2 diabetic retinopathy model in rats
exploring the efffects of calcium dobesilate on the model.Method: SD rats were randomly divided into normal group and model group
model rats with high fat diet for 3 months
then ip STZ(45 mg·kg-1) one times.12 weeks later
the model rats were randomly divided into model group and drug group.Drug group ig daily calcium dobesilate(150 mg·kg-1).After the administration period
detection of retinal tissue malondialdehyde(MDA)
superoxide dismutase(SOD)
glutathione(GSH)
vascular endothelial growth factor(VEGF)
glycosylated of products(AGEs) and other indicators.Result: Compared with model group
drug group SOD activity
VEGF expression are significantly different(P <0.05)
but GSH
MDA content and the expression of AGEs was not significantly different.Changes of the aboved index proved that the model was successful.Conclusion: The experimental rat model was established successfully.It may provide a perfect animal model for investigating type 2 diabetic retinopathy and pharmacology successful.
