Abstract

Objective: The aim of this experimental study was to investigate the effects of tamoxifen versus unopposed estradiol in an oopherectomised rat model. Materials and Methods: Sixty female rats weighing approximately 285g were divided into four groups. At the beginning, 15 rats were necropsied and served as controls (Group I). The other three groups of rats were ovariectomized and then were given estradiol (Group II), tamoxifen (Group III) or standard chow only (Group IV-castration). Estradiol was given intramusculary at 0.1 mg/kg/d and tamoxifen was given by gavage at I mg/kg/d for five weeks. Serum lipid levels, body and uterine weight, and endometrial myometrial thickness were recorded at the end of the study Data were presented as the mean ± SEM. Comparison of baseline and five-week measurements for each group were compared by two- way repeated measures ANOVA. P

Özet

Amaç: Ooferektomize rat modelinde tamoksifenin Karşılanmamış östrojen agonistik etkilerini araştırmak Matcryal-metod: Ortalama ağırlıkları 285 gram olan 60 adet dişi rat dört gruba ayrıldı. 15 rat kontrol grubunu oluşturdu (Grup I) ve diğer 45 raf a ooferektomi uygulandıktan sonra 5 hafta süreyle estradiol (Grup II), tamoksifen (Grup III) veya standard gıda verildi (Grup IV-Menopoz grubu). Çalışma sonu vücut ve uterin ağırlık, serum lipidleri, endometrial-myometrial kalınlıklar kaydedildi ve karşılaştırmada iki yönlü ANO VA kullanıldı. Bulgular:Menopoz grubunda vücut ağırlığı ve HDLc düzeyleri önemli ölçüde yüksek, tamoxifen veya estradiol grubunda LDLc düzeyleriönemliölçüdedüşükidi(p0.05).Tamoksifen grubunda HDLc/LDLc diğer gruplardan anlamlı yüksek olmasına karşın estradiol grubundaki oran Grup III den daha yüksekti (p0.05), ancak endo-myometrial kalınlık artışları anlamlı ölçüde yüksekti (p
