Abstract

Objectives; To investigate the relationship between ornithine treatment, p53 expression and the histopathologic differentials of rats' inner ear in endotoxemia induced by lipopolysaccharide. Material and methods; Twentyfour healthy rats were randomly divided into 4 groups. The first group, served as control, received intraperitoneal saline; the second group, intraperitoneal endotoxin; the third group, intraperitoneal ornithine and saline, and the fourth group received intraperitoneal ornithine ten minutes before endotoxin administration. Results; Congestion and subepitelial edema were observed in stria vascularis, and leukocyte, plasma cell infiltration in the parts of membraneuos labyrinthitis of modiolar region in the cochlea of the second and the fourth group. Inflammation was not detected in the parts of vestibulocochlear and facial nerves in meatus acousticus internus. When we compared the plasma levels of nitrite/nitrate and MDA among groups, we found statistically significant differences: between groups 1 and 2, 1 and 3, 1 and 4, 2 and 3, 3 and 4. However, no significant difference was found in groups 2 and 4. Ornithine did not reduce the harmful effect of sepsis in rats. Immunohistochemically, p53 immunoreactive cells were not detected in any groups. Conclusion; L-ornithine can not improve the manifestations of septic picture in the rat cochlea.

Özet

Amaç: Lipopolisakkarit ile oluşturulan endotoksemide rat iç kulak histopatolojisi ile ornitin tedavisi ve P 53 ekspresyonu arasındaki ilişkinin araştırılması. Gereç ve Yöntemler: Yirmi dört sağlıklı rat rasgele dört gruba ayrıldı. Birinci grup kontrol grubu olarak seçildi ve intra peritoneal serum fizyolojik verildi; İkinci gruba intraperitoneal endotoksin; Üçüncü gruba intraperitoneal ornitin ve serum fizyolojik, dördüncü gruba endotoksin ve ornitin verildi. Bulgular: İkinci ve dördüncü grup ratların stria vaskülarislerinde konjeyon, supepitelyal ödem ve modiolusun membranöz labirent bölümünde lökosit ve plazma hücre infiltrasyonu gözlendi. Meatus akustikus internusta yer alan vestibulokoklear ve fasiyal sinirlerde enflamasyon saptanmadı. Gruplar arasında plazma nitrit/nitrat ve MDA seviyelerini karşılaştırdığımızda, birinci ile ikinci, birinci ile üçüncü, birinci ile dördüncü, ikinci ile üçüncü, üçüncü ile dördüncü gruplar arasında istatistiksel olarak anlamlı fark bulduk. Buna karşın, iki ile dördüncü grup arasında anlamlı bir fark bulunamadı. İmmünohistokimyasal olarak hiçbir grupta p53 immünreaktif hücre saptanmadı. Sonuç: L- ornitin rat kokleasındaki septik bulguları düzeltememektedir.
