摘要
使用环孢霉素A(CSA)滴眼液和妥布霉素地塞米松滴眼液联合用药,对犬高危穿透性角膜移植手术术后进行抗免疫排斥治疗,以探讨其对该手术术后的疗效。选择30只健康本地犬建立犬角膜高危病理模型,继而行穿透性角膜移植手术,术后将试验犬随即分为2组,生理盐水对照组15只,环孢霉素A滴眼液+妥布霉素地塞米松滴眼液组15只,分别于术后第2天进行滴眼治疗,6次/d,2滴/次,用药组进行交替药物滴眼,两次滴眼间隔2h,并对术眼进行眼压测定、组织病理学检查和裂隙灯检查,观察术后各组角膜免疫排斥情况和角膜组织结构情况。试验结果显示,用药组角膜发生免疫排斥的平均时间为49.33±9.61d,生理盐水组角膜发生免疫排斥的平均时间为10.83±2.93d,两组相比差异性极显著(P<0.01)。术后第5天测定所有术犬术眼眼压,结果均在正常范围内(10～20mmHg)。生理盐水组角膜组织结构发生了严重的变化和破坏,随着时间的推移呈严重发展趋势,用药组整个观察期角膜组织结构未发生明显变化。
To explore the curative effect of CSA combined with TobraDex eye drops on immunological rejection after high-risk penetrating keratoplasty（PKP） in canis.30 local dogs were chosen to be burnt as high-risk Pathological model and to be PKP.All of them were randomly average divided into two groups： normal saline group and CSA＋TobraDex group.Each of them had 15 dogs which were treated by eye drop at the second day after PKP and kept the eye drops 6 times/day and 2 drops/each time.Medication group used different eye drops alternately,2 hours/period time.To observe immune rejection and the structure of cornea after PKP,we took the intraocular pressure examination.,histopathologic examination and slit-lamp examination.The result showed that the rejection time of medication group and normal saline group was 49.33±9.61 day,10.83±2.93 day respectively.The difference between these two groups was very significant（P0.01）.The IOP of all the dogs were in the normal range（10~20 mmHg） at days after PKP.The structure of Cornea organization in normal saline group was changed and destroyed.The structure of cornea in medication group was normal during the whole observation period.
