Oxidant/Antioxidant status of plasma in Arabian mares with uterine lymphatic cysts

Uterus kistleri kısraklarda fertilite kaybına neden olan önemli faktörlerden biridir. Lenfatik uterus kisti olan kısraklardaki plazma oksidan-antioksidan dengesini inceleyen bir araştırmaya rastlanmamıştır.Bu çalışmada, lenfatik uterus kisti bulunan kısraklarda plazma oksidan (malondialdehit [MDA]) ve antioksidan (glutatyon [GSH], ß-karoten, E vitamini konsantrasyonları ile glutatyon peroksidaz [GSH-Px] ve katalaz aktiviteleri) dengesi araştırıldı. Bu amaçla, yaşları 15-20 arasında değişen 10 uterus lenfatik kistli ve 8 sağlıklı Arap kısrağından kan örnekleri toplandı.E vitamini, ß-karoten, GSH ve MDA konsantrasyonlarında gruplar arasında önemli bir farklılık gözlenmedi. Lenfatik uterus kistli kısraklardaki plazma beta-karoten seviyesinin ise sağlıklı kısraklarınkinden düşük olduğu tespit edildi (P

Lenfatik uterus kistli arap kısraklarında plazma oxidan-Antioxidant değerleri

Uterine cysts are one of important contributing factor to subfertility in the mare. There are no data concerning blood oxidant and antioxidant status in mares with lymphatic uterine cysts.Therefore, this study was conducted to investigate plasma oxidant (malondialdehyde [MDA]) and antioxidant (glutathione [GSH], ß-carotene, vitamin E, glutathione peroxidase [GSH-Px], catalase [CAT]) status in mares with uterine cysts. For this purpose, blood samples were collected from 10 mares with uterine lymphatic cyst and 8 healthy Arabian mares. The age of the mares varied from 15 to 20 years.There were no significant differences in the concentrations of vitamin E, GSH, MDA and activity of CAT and GSH-Px between groups. However, the concentration of plasma ß-carotene in the mares with uterine cyst was significantly lower (P
