RAT OVERİNDE OLUfiTURULAN ADNEKSİYAL TORSİYON MODELİNDE PERİOPERATİF SELENYUM VE C VİTAMİNİ UYGULAMASININ OVARYAN NEKROZ ÜZERİNE ETKİNLİĞİNİN DEĞERLENDİRİLMESİ
Abstract
Giriş: Ovaryan torsiyon jinekolojik onkolojide adneksiyal kitlelerin
komplikasyonu olabilen, konservatif yaklaşım olarak ilgili segmentlerin
detorsiyonunu içeren ciddi bir jinekolojik problemdir. Torsiyon,
ovaryan hasar ve fertilite kaybı ile kendini gösterir ve detorsiyon
hasarın artmasında en önemli faktörlerden biridir. Torsiyon/Detorsiyon
şeklinde görülen ovaryan hasar diğer organlarda gözlenen
iskemi/reperfüzyon (I/R) hasarıyla benzerlik göstermektedir.
Amaç: Bu deneysel çalışmada amaç rat overinde, iskemi/reperfüzyon
hasarında C vitamini ve selenyumun etkilerini değerlendirmektir.
Gereç ve Yöntem: Bu çalışmada 48 adet wistar cinsi rat kullanıldı.
Sham grubunda (grup 1) sadece laparotomi uygulandı. İskemi (Grup
2) grubunda ovaryan iskemi oluşturuldu ve sağ over 4 saat sonra çı-
karıldı. İskemi/Reperfüzyon (Grup 3) grubunda 4 saatlik iskemik periodun
ardından, 1 saat reperfüzyon uygulandı ve sağ over çıkarıldı.
Grup4, Grup5 ve Grup6’da 4 saatlik iskemik periodun ardından sırasıyla
C vitamini, selenyum, selenyum+C vitamini, reperfüzyon öncesi
infüzyonla verildi, 1 saatlik reperfüzyonun ardından sağ over çıkarıldı.
Overler daha sonra histopatolojik olarak değerlendirildi.
Bulgular: Sham grubunda nekroz bulgusu görülmezken, hücre
hasarı en çok selenyum ve C vitaminin beraber uygulandığı grupta
gözlendi. İskemi grubunda iskemi/reperfüzyon grubuna göre daha
az hücre hasarı görüldü. C vitamini ve selenyumun tek başına verildi-
ği gruplar iskemi grubuyla benzerlik gösterirken; iskemi/reperfüzyon
grubundan aha az hücre hasarı izlendi.
Sonuç: C vitamini ve selenyum iskemi/reperfüzyon hasarını
azaltmada etkilidir.

Abstract
Introduction: Ovarian torsion is a serious gynaecologic problem
in gynecologic oncology where conservative management includes
detorsion of the involved segments. Torsion has been implicated in
ovarian damage and loss of fertility, and detorsion in one of the most
important factors in further injury. Ovarian injury resulting from torsion/detorsion
resembles that caused by ischemia/reperfusion (I/R)
injury observed in other organs.
Aim: In this experimental study, the aim is to examine the effects
of Vitamin C and selenium on ischemia-reperfusion injury in the rat
ovary.
Materials and Methods: In this study 48 female Wistar rats were
used. In the Sham group(Group 1) only laparotomy was performed.
In group 2 (ischemia) ovarian ischemia was produced and the right
ovary was surgically removed 4 h later. In group 3(ischemia/reperfusion
) an ischemic period of 4 h was followed by reperfusion for 1 h,
the right ovary was removed. In groups 4,5 and 6, after 4h of ischemia,
either vit C, selenium, selenium+vit C respectively were infused
before reperfusion; after 1 h of reperfusion the right ovary was
removed. The ovaries were examined by histopathologic evaluation.
Results: There was no cell injury in the Sham group but we determined
significant difference in the group of Vit C and selenium
infused together. In the ischemia group we determined cell injury was
less than ischemia/reperfusion group. The groups that have been
infused Vit C and selenium respectively, were similar with ischemia
group, but less than ischemia/reperfusion group.
Conclusion: We concluded that Vit C and selenium are effective
in decreasing ischemia/reperfusion injury
