The aim of this study was to determine the oxidative/nitrosative stress, leptin and progesterone concentrations in pregnant and non-pregnant Abaza goats after synchronization with controlled internal drug release (CIDR) during the breeding season. For this purpose, 40 clinically healthy Abaza goats, aged 2-4 years, were intravaginally exposed to CIDR on day 0, and injected with equine chorionic gonadotropin and prostaglandin F2α on day 9 of the experiment. CIDR was removed on day 11. At the end of the experiment, they were monitored for estrus and exposed to fertile males for mating. Blood samples were collected 8 days before synchronization, then on days 0, 11 of CIDR insertion and on mating day. A pregnancy diagnosis was conducted using transrectal ultrasonography 30 day after mating. The blood serum from 40 goats (30 pregnant + 10 non-pregnant) was used for biochemical analyses. Malondialdehyde (MDA), nitric oxide (NO), total oxidant capacity (TOC), total antioxidant capacity (TAC) and endothelial NO synthase (eNOS) activities were significantly higher on mating day in pregnant goats compared to non-pregnant goats (P
Bu çalışmanın amacı üreme sezonunda controlled internal drug release (CIDR) ile senkronizyon sonrasında gebe ve gebe olmayan Abaza keçilerinde oksidatif/nitrosatif stres, leptin ve progesteron konsantrasyonlarının belirlenmesidir. Bu amaçla, klinik olarak sağlıklı 2-4 yaşlı 40 Abaza keçisine 0. gün CIDR intravaginal olarak yerleştirildi ve 9. gün equine chorionic gonadotropin ile prostaglandin F2α enjekte edildi. CIDR 11. gün çıkarıldı. Uygulama sonrasında östrus takibi yapılarak keçiler fertil tekeler ile çiftleştirildi. Senkronizasyona başlamadan 8 gün önce, 0. gün, 11. gün ve çiftleşme günü kan alındı. Çiftleşmeden sonraki 30. gün transrektal ultrasonografi ile gebelik muayenesi yapıldı. Biyokimyasal ölçümler için 40 keçiden (30 gebe + 10 gebe olmayan) elde edilen kan serumu kullanıldı. Gebe olan keçilerle gebe olmayan keçiler karşılaştırıldığında malondialdehid (MDA), nitrik oksit (NO), total oksidan kapasite (TOC), total antioksidan kapasite (TAC) ve endotelyal NO sentaz (eNOS) aktiviteleri anlamlı olarak yüksek bulundu (P
