Abstract

The primary objective of this study was to investigate the role of acetylcysteine on the treatment of experimentally induced corneal defects in dogs. Seven dogs, 5 males and 2 females, were used in this study. After anesthesia a corneal defect (lamellar keratectomy) at the center of right and left corneas of each dog was created with an trephine of a 7.5 mm in diameter. Then, it was administered to the left eye of each dog 3% acethylcysteine and to the contralateral right eye serum physiologic 3-4 drops each eye and three times per day for two months. During clinical examination, it was observed that corneal opacity disappeared in 20 days in left eyes contrary to any progress in the right eyes. At the end of the study, three randomly selected dogs were killed and the corneal wound healing processes of their both eyes were biomicroscopically and histhopatologically evaluated. Biyomicroscopic examination revealed that the boandries of the defect, at the right eyes were evident whereas those at the left eyes were not distinctly evident. On the histopatologic examination, it was; observed that there was a marked healing on the corneal epithelial layer of the left eyes in contrast to incomplete corneal epithelial healing on the right eyes. As a result, acetylcysteine was found to have a marked induction on corneal wound healing process in dogs.

Özet

Bu çalışma, köpeklerde deneysel olarak oluşturulan korneal defektlerin sağaltımında asetilsisteinin etkinliğini araştırmak amacıyla yapılmıştır. Çalışmada 5'i erkek 2'si dişi olmak üzere toplam 7 adet sağlıklı köpek kullanıldı. Hayvanlar anesteziye alındıktan sonra aynı hayvanın her iki gözünde korneanın tam merkezine gelecek şekilde 7.5 mm çapında bir trepan yerleştirilerek korneal defekt (lamellar keratektomi) oluşturuldu. Köpeklerin sol gözlerine % 3'lük asetilsistein, sağ gözlerine ise % 0.9'luk serum fizyolojik günde üç kez 3-4 damla iki ay süreyle damlatıldı. Klinik incelemeler sonucunda, sol gözlerde korneal.bulanıklığın 20. günde kaybolduğu görülürken, sağ gözlerde iyileşme görülmedi. Çalışmanın sonunda rastgele 3 hayvan seçilerek ötenazi edildikten sonra korneadaki yara iyileşmesi biyomikroskopik ve histopatolojik olarak değerlendirildi. Biyomikroskopik incelemelerde sağ gözlerde defekt sınırları belirgin bir şekilde tespit edilirken, sol gözlerde defekt sınırları belli belirsiz bir durumdaydı. Histopatolojik incelemelerde ise sağ gözlerde korneal iyileşme tam olarak gelişmezken, sol gözlerde kornea epitelinde tam bir iyileşme tespit edildi. Sonuç olarak; asetilsisteinin korneal yara iyileşmesi üzerine önemli bir etkisinin olduğu kanısına varıldı.
