Abstract:
Objectives: To observe the therapeutic effects of collagen corneal shields (CCS) combined with fibronectin (FN) and epidermal growth factor (EGF) on healing of rabbit corneal wound caused by mustard gas, and to look for the new methods,new technology and new medicine to treat the injured cornea before eyelid edema observed in field hospital.Methods: After the left cornea was contaminated with mustard gas, 24 rabbits were equally divided into three groups(groups A, B, C) at random. Groups A,B,C were treated with PBS,CCS and CCS+FN+EGF,respectively. The corneas were stained with fluorescein and photographed 2, 8, 16, 24, 36,72 hours after contamination. The rate of corneal epithelial healing and percentage of damage were calculated. Results:The healing rates of groups A,B and C were (0.879±0.139)mm2/h, (1.223±0.166)mm2/h and (1.543±0.224)mm2/h,respectively and had statistically significant difference(P<0.01). The percentage of damage was 71.6%, 57.3% and 44.8%,respectively and also had statistically significant difference(P<0.01).Conclusions: The treatment with CCS can accelerate the corneal epithelial healing injured by mustard gas and the therapeutic effects will be better if CCS is combined with FN and EGF.
