Abstract

Summary: This study was conducted to investigate plasma estradiol 173 and progesteron profiles, oxidant/ antioxidant status and the relationship among these parameters during the period from the day of ovulation until embrional fixation day in mares. Blood samples were collected on the day of ovulation (d=0) and on days 5, 10, and 16 of pregnancy in 12 purebred mares. Plasma was analyzed for oxidant (malondialdehyde, index of lipid peroxidation) and antioxidants (Vitamin E, 8-carotene, glutathione, catalase, glutathione peroxidase) values. Estradiol 178 level decreased after ovulation while, progesteron level gradually increased (p<0.05). Plasma malondialdehyde level on days 5 and 16 of pregnancy significantly were higher than d 0 (p<0.05). Plasma antioxidant parameters except for vitamin E gradually increased and this increase on 16th day was significantly higher than on day of ovulation day. Moreover, a negative correlation was observed (r=-0.50) between the plasma estradiol 173 and malondialdehyde concentrations. In conclusion, plasma malondialdehyde level generally increased, however the concentrations of 3-carotene, glutathione and activities of glutathione peroxidase and catalase parallelly increased during the period from the day of ovulation until embrional fixation day in mares.

Özet

Özet: Bu çalışmada, kısraklarda gebeliğin fiksasyona kadar olan döneminde plazma 178 östradiol ve progesteron hormon profilleri, oksidan/antioksidan seviyeleri ve bunlar arasındaki ilişkilerin belirlenmesi amaçlandı. Bunun için 12 adet safkan kısraktan ovulasyon günü (0. gün), gebeliğin 5., 10. ve 16. günlerinde kan numuneleri alındı. Plazma 178 östradiol, progesteron konsantrasyonları ile oksidan (malondialdehit; lipit peroksidasyon indeksi) ve antioksidan (E vitamini, 8-karoten, glutatyon, katalaz, glutatyon peröksidaz) değerleri ölçüldü. 173 östradiol seviyesi ovulasyondan sonraki günlerde düşerken (p<0.05), progesteron seviyesinin giderek yükseldiği (p<0.05) görüldü. Plazma malondialdehit seviyesindeki artış 5. ve 16. günlerde önemli bulundu (p<0.05). E vitamini haricindeki diğer antioksidan parametrelerin ise genellikle tedricen artarak 16. günde ovulasyon gününe kıyasla önemli derecede yüksek (p<0.05) olduğu gözlendi. Ayrıca, plazma malondialdehit ve 17B östradiol konsantrasyonları arasında önemli bir negatif korelasyon (r=-0.50) olduğu görüldü. Sonuç olarak, kısraklarda gebeliğin fiksasyona kadar olan döneminde plazma malondialdehit seviyesinde genel bir artış görülürken, buna karşı B-karoten ve glutatyon konsantrasyonları ile glutatyon peröksidaz ve katalaz aktivitelerinin arttığı gözlendi.
