METHODS: Adult male Wistar rats, 9 weeks of age, were injected intraperitoneally with STZ to create diabetes. At 2 week after the models were created, BDNF protein was administered into the vitreous cavities of rats. At 4 week after the models were created, the rats were killed and the retina was removed for Western blotting and Whole-mount immunohistochemistry for TH to observe the changes of TH and dopaminergic amacrine cells in retina.
