BACKGROUND:Chitosan nanoparticles-encapsuled sodium hyaluronate is an effective drug for the burned cornea. OBJECTIVE:To verify the effect of sodium hyaluronate/chitosan nanoparticles on the neovascularization in burned cornea. METHODS:Thirty Sprague-Dawley rats were randomly divided into three groups, and the model of burned cornea caused by base was established in the rats of model and experimental groups, fol owed by respectively treated with 10μL sodium hyaluronate/chitosan nanoparticle suspension and normal saline, once daily, for consecutive 4 weeks. Rats only given normal saline were used as controls. Four weeks later, the dynamic growth of newly formed blood vessels in the cornea was observed using silt lamp. The levels of tumor necrosis factor-αand interleukin-6 were detected by ELISA, histological changes of the cornea were observed by hematoxylin-eosin staining, and the mRNA expression levels of vascular endothelial growth factor and cyclooxygenase 2 were detected by real-time PCR. RESULTS AND CONCLUSION:Compared with the control group, the area of the newly formed blood vessel and the levels of tumor necrosis factor-α, vascular endothelial growth factor and cyclooxygenase 2 were significantly increased in the model group (P<0.05, P<0.01). In the experimental group, al above indicators were significantly lower than those in the model group (P<0.05). There were a large number of inflammatory cel s and neovascularization in the model group, but only few inflammatory cel s in the experimental group. These results show that sodium hyaluronate/chitosan nanoparticles can inhibit the neovascularization in the burned cornea.

BACKGROUND:Chitin has been found to be a good biomaterial, but research on chitin carrying corneal epithelial cel s for rabbit corneal epithelial injury is little reported. OBJECTIVE:To investigate the repair outcomes of chitin hybrid membrane carrying corneal epithelial cel s in the rabbit corneal epithelial injury.METHODS:Eighteen New Zealand white rabbits were enrol ed and made into left corneal epithelial injury models, and then randomized into two groups and treated with chitin hybrid membrane carrying corneal epithelial cel s (experimental group) and chitin hybrid membrane (control group), respectively. The damage area, histological changes and ultrastructure of the cornea were observed at 1, 3, and 7 days after implantation. RESULTS AND CONCLUSION:Damage area of the cornea in the experimental group was significantly less than that in the control group at 1 and 3 days after implantation (P<0.05), and the cornea in both two groups healed wel at 7 days after implantation. At 7 days after implantation, in both two groups, the corneal epithelium with six layers adhered to the corneal stroma closely, which was repaired completely and regularly. Comparatively speaking, the cornea in the experimental group possessed smooth outer layer. Besides, in the experimental group, the hexagonal corneal epithelial cel s arranged closely with flat surface;while the hexagonal corneal epithelial cel s in the control group showed no smooth surface and gaps between cel s. These results indicate that chitin hybrid membrane carrying corneal epithelial cel s promotes the repair of rabbit corneal epithelial injury.
