摘要 目的:探讨表皮生长因子对糖尿病大鼠角膜上皮损伤修复的影响。方法:将SD雄性大鼠28只随机分为正常未治疗组(6只)、正常治疗组(6只)、糖尿病未治疗组(8只)、糖尿病治疗组(8只)。采用链脲佐菌素(STZ)65mg/kg左下腹腔一次性注射制作糖尿病大鼠模型。4周后,将大鼠全麻后制作右眼角膜上皮损伤模型,损伤后0h,12h,18h,24h分别行角膜荧光素染色显示损伤的区域,眼前节分析系统照相并分析损伤区域的面积。结果:角膜上皮损伤修复速度糖尿病组比正常组慢,组间差异具有统计学意义(P<0.05);治疗组的角膜上皮损伤修复速度比未治疗组快,组间差异无统计学意义(P>0.05)。结论:糖尿病可使大鼠角膜上皮损伤修复延迟,但因角膜上皮修复较快,表皮生长因子促进糖尿病大鼠角膜上皮损伤修复的影响不明显。
