dnexal torsion is the fifth leading cause of emergency gynecological surgery in spite of being seen rare. It is often seen in women with reproductive age, although it can be seen in prepubertal and postmenopausal period.1 Early diagnosis and treatment plays an important role in maintain the fertilization. Laparoscopy is a precise diagnosis and treatTurkiye Klinikleri J Lab Anim 2017;1(2):71-7
71Protective Effects of Dexmedetomidine on Ischemia-Reperfusion Injury in Rat Ovary A AB BS ST TR RA AC CT T O Ob bj je ec ct ti iv ve e: : Aim of this study is to evaluate the protective effect of dexmedetomidine on the histopathology and biochemical parameters in reducing damage in ischemia/reperfusion injury in rats ovary and to compare the effect of two different doses of dexmedetomidine. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : Forty-two adult female Wistar Albino rats were used. Rats were separated into six groups: Sham, Torsion, Torsion+Detorsion, Torsion+Detorsion+Salin, Torsion+Detorsion+ Dexmedetomidine 10 µg/kg, and Torsion+Detorsion+Dexmedetomidine 20 µg/kg. Exception of the Sham group, ovarian torsion procedure was performed to all groups for 2 hours. Detorsion procedure was implemented to all groups for 2 hours, exception of Torsion group. Medications were given intraperitoneally half an hour before the detorsion procedure in Salin, Dexmedetomidine 10 µg and 20 µg groups. Then 2 mL of blood samples were drawn for markers of oxidative stress. The right ovaries were separated from all rats. R Re es su ul lt ts s: : The oxidative stress levels and histologic scores values of ovarian tissues were higher in Torsion+Detorsion group than in Sham group (p<0.001). By the uses of dexmedetomidine 10 and 20 µg, a significant decrease was established in the mean levels of oxidant markers and histopathologic scores. C Co on nc cl lu us si io on n: : Administration of dexmedetomidine 10 µg and 20 µg are effective in preventing tissue damage by ischemia\reperfusion injury in ovarian torsion. However, there was no difference between the dexmedetomidine 10 µg and 20 µg treatments with regards to protective activity. K Ke ey yw wo or rd ds s: : Ovary; dexmedetomidine; reperfusion injury Ö ÖZ ZE ET T A Am ma aç ç: : Bu çalışmanın amacı rat overlerinde deneysel olarak oluşturulan iskemi\reperfüzyon hasarına karşı deksmedetomidin tedavisinin koruyucu etkinliğini değerlendirmek ve iki farklı deksmedetomidin dozlarını karşılaştırmaktır. G Ge er re eç ç v ve e Y Yö ön nt te em ml le er r: : Bu çalışmada 42 tane dişi Wistar Albino rat kullanıldı. Ratlar her biri yedişer rat olmak üzere 6 gruba ayrıldı: Sham opere, Torsiyon, Torsiyon-Detorsiyon, Torsiyon+Detorsiyon+ İzotonik sodyum klorür, Torsiyon-Detorsiyon+ Deksmedetomidin 10 µg ve Torsiyon-Detorsiyon+ Deksmedetomidin 20 µg. Sham opere grubu hariç diğer tüm gruplara iki saat boyunca ovaryan torsiyon işlemi uygulandı. Torsiyon grubu dışındaki diğer tüm gruplara 2 saat detorsiyon prosedürü uygulandı. Salin, Deksmedetomidin 10 µg ve Deksmedetomidin 20 µg gruplarında y...
