Abstract

The aim of this study was firstly to determine the relationship between estrous cycle and oxidative stress inreproductive tissues in bitches. This research was performed in twenty-nine healthy bitches from different breeds and of varied ages(the range was 2-5 years) that were brought to the clinic for routine ovariohysterectomy. The stages of estrous cycle were detectedusing by vaginal cytology, blood progesterone level and histological findings. Ovarian, oviduct and uterine tissues were taken intoEppendorf tubes for oxidative stress index and stored at -80°C until analyses. Also, another part of these tissues were fixed in 10%formalin solution. There were no significant differences (P > 0.05) among total antioxidant status (TAS), total oxidant status (TOS)and oxidative stress index (OSI) values in the reproductive tissues in concerning estrous cycle stages. However, there were remarkablecorrelations between oxidative stress parameters and reproductive tissues in different estrus stages in bitches. In conclusion, thephysiological values of TAS and TOS concentration, and OSI in the ovarian, oviduct and uterine tissues during estrous cycle werefirstly defined in this article. The serum thiol/disulphide homeostasis was also determined in the estrous cycle of bitches. We havefound that there are remarkable variations of oxidative stress balance in the ovary, oviduct and uterus concurrently, during estrous cyclein the bitches. Besides, significant correlations between oxidative stress parameters and estrous cycle stages in the reproductive tissueswere observed in the present study.

Özet

Bu çalışmada, köpeklerde östrus siklusu ile reprodüktif organlardaki oksidatif stres arasındaki ilişkinin ilk olarak ortaya konulması amaçlandı. Bu araştırma, rutin ovaryohisterektomi için kliniğe getirilen farklı ırklardan ve değişik yaşlardan (2-5 yıl arasında) sağlıklı yirmi dokuz köpekte gerçekleştirildi. Östrus siklusunun evreleri vajinal sitoloji, kan progesteron seviyesi ve histolojik bulgular ile tespit edildi. Ovaryum, ovidukt ve uterus dokuları, oksidatif stres indeksinin belirlenmesi için Eppendorf tüplerine alındı ve analiz edilene kadar -80°C'de saklandı. Ayrıca, bu dokuların diğer bir kısmı %10 formalinde fikse edildi. Reprodüktif organlardaki total antioksidan durum (TAS), total oksidan durum (TOS) ve oksidatif stres indeksi (OSI) düzeylerinde östrus siklusu evreleri bakımından istatistiksel bir fark bulunmadı (P > 0,05). Ancak östrus siklusunun farklı evrelerinde oksidatif stres parametreleri ile reprodüktif dokular arasında dikkat çekici korelasyonlar belirlendi. Sonuç olarak, bu araştırma ile köpeklerde östrus siklusu boyunca ovaryum, ovidukt ve uterus dokusundaki TAS, TOS ve OSI’nin fizyolojik değerleri ilk kez ortaya konuldu. Ayrıca köpeklerde östrus siklusunun evrelerine göre serum thiol/disülfit homeostazisi de belirlendi. Bununla birlikte, reprodüktif dokulardaki oksidatif stres parametreleri ile östrus siklusunun evreleri arasında önemli korelasyonların olduğu gözlendi.
