ABSTRACT
Objective: To observe the remodeling of diabetic microvessels in diabetic rats. Methods: Diabetic animal models were induced by STZ on SD rats. The rats were treated with nonenzymatic glycosylation inhibitor and blood flow activating and stasis removing traditional Chinese medicine to evaluate the remodeling of diabetic retinal microvessels by trypsin digestion and figure analysis. Results: At 8 weeks, significant alteration of retinal capillary width in diabetic rats were observed( P
ABSTRACT
The histopathological changs of the dog eyes caused by acute and subacute toxic effectsof hematoporphyrin monoether--PsD-044 were observed in this research. The results showed thatPsD-044 could lead to keratoscleritis and scleral perivasculitis. Phototoxic cyclitis and inflammatory edema of the retina were more serious in deferred killed animals, suggesting that it is necessary to avoid exposure to light after the administration of PsD-044.
