Each group consisted of four rabbits. Eight eyes in group 1were subconjunctivally received interferon α-2b 5 × 105IU/0. 2ml into filtering blebfrom the edge of the filtering site immediately after operation and every postoperativeday. The other eight eyes in group 2 were injected with 0. 2ml normal saline. All ofthe eyes underwent daily examination by slip-lamp microscopy and directophthalmoloscopy. Sodium fluorescein was used to assess corneal epithelial integrity.On day 3,4,7 and 14, every two rabbits (group 1 and 2 each, respectively) werekilled and removed cornea immediately to take examination of the viability of cornealendothelium by dual staining with typan blue and alizanin red S.Results: No sign of toxicity in corneal epithelium and endothelium were展开更多

Postoperatively one eye of each rabbit received subconjunctival injections of HH liposome and fellow eye received saline injection in a randomized masked fashion.Results; Fourteen days after operation the IOP of experimental eyes reduced significantly (P < 0.01) as compared with the controlled eyes, and the number of remaining filtering blebs increased noticeably (P< 0.05). Pathohistological examination revealed that the number of fibroblasts per square micron in the filtering sites and the thickness of the scars in the center of the filtering sites of the experimental eyes were less than those of the controlled eyes. No serious ocular toxic and side effects were found.Conclusion : This experiment suggests that homoharringtonine liposome can markedly inhibit the scar formation of filtering sites after glaucoma展开更多
