Abstract

OBJECTIVE: To examine the effect of human menopausal gonadotropin(HMG) and follitropinBeta (rFSH) on the ovarian histologies in a rat model. STUDY DESING:Thirty-nine female, one-year old rats were enrolled for the trial. They were divided into three groups. In the first group, 13 rats received, six cycles of ovulation induction with human menapausal gonadotropin.In the second group, 13 rats received six cycles of ovulation induction with folitropin beta the third study group consisted of 13 rats which received six cycles of saline intramuscularly. RESULT: The mean number of the cells that stained positive for Ki-67 was 42.3±20.6, 44.9±27.3and 42.5±24.8 in the folicles, respectively.The mean number of cells that stained positive for Ki-67 in epithelium was 0.15±0.42, 0.04±0.14,0.05±0.18, respectively. The mean dysplasiascore was 2.46±2.10, 1.69±13 and 1.62±1.89 in the ovarian epithelial cells respectively. CONCLUSION:Development of malignant lesion were not found in any of the rat ovaries after ovulation induction. As a result of this study, we found out that human menapausal gonodotropin and folitropin beta used in treatment of infertility, when administered for six cycles in accordence with the dosage determined, do not have the potential to develop neoplasia in rats.

Özet

AMAÇ: Bu çalışmanın amacı overian histoloji üzerine ovulasyon indük siyonunu etkilerinin rat modelinde incelenmesidir. Bu amaçla otuz dokuz adet bir yaşında dişi rat kullanıldı. GEREÇ ve YÖNTEM: Ratlardan üç gurup oluşturuldu. İlk guruptaki 13 rata ovulasyon indüksiynu için altı siklus human menapozal gonodotropin ikinci guruptaki 13 rata 6siklus follitropin beta verildi. Üçüncü guruptaki 13 rata intramuskuler olarak altı siklus salin uygulandı.Altı siklus sonra bilateral ooferektomi uygulandı. BULGULAR: Over epitelinin displazi scoru ve Kİ-67 ekspresyonu incelendi.Ortalama olarak folliküllerde Ki-67 pozitif saptanan hücre sayıları sırasıyla 42.3±20.6, 44.9±27.3 ve 42.5±24.8 olarak bulundu. Epitelde Ki-67 pozitif sap tanan hücre sayıları ortalama olarak sırasıyla 0.15±0.42, 0.04±0.14, 0.05±0.18 olarak saptandı. Over epitelindeki ortalama displazi skoru sırasıyla 2.46±2.10, 1.69±13 and 1.62±1.89 olarak saptandı. Ovulasyon indüksiyonu sonrasında hiçbir rat overinde malign lezyon gelişimi saptanmadı. SONUÇ: Rat modelinde altı siklus boyunca tanımlanan dozlarda kullanılan human menopozal gonodotropin ve folitropin beta neoplazi gelişimi için potansiyel sebep oluşturmamıştır.
