Abstract

OBJECTIVE: This study evaluated the effect of simvastatin at different doses on rat proximal femur and lumbal vertebra bone mineral density (BMD) in rats receiving estrogen replacement therapy. MATERIAL-METHOD: Fouty-eigth Wistar Albino rats were divided into six groups, containing 8 rats each. Ooforectomy was performed to the rats of the first 5 groups, whereas the last group was sham operated. Four groups of ooforectomized rats were treated with 150 μg/kg body weight/day 17 β-estradiol and/or high (6 mg/kg body weight/day) or low (3 mg/kg body weight/day) dose simvastatin for 120 days by gavage. BMD of the proximal femur and lumbal vertebra were compared between groups at the end of the study RESULTS: Proximal femur BMD of ooforectomized rats decreased significantly (0.145 ± 0.01 g/cm² ve 159 ± 0.01 g/cm²; p=0.001), whereas the lumbal vertebral bone loss did not reach statistical significance (0.161 ± 0.01 g/cm² ve 0.168 ± 0.01 g/cm²; p=0.471). 150 μg/kg body weight/day 17 β-estradiol treatment preserved proximal femur and lumbal vertebra BMD. The effect of 150 μg/kg body weight/day 17 β-estradiol and 3 mg/kg body weight/day on proximal femur and lumbal vertebra BMD were comparable. The estrogen and low dose simvastatin combination povided greatest protection of proximal femur (0.176 ± 0.01 g/cm² ve 0.145 ± 0.01 g/cm²; p

Özet

AMAÇ: Ooforektomize sıçanlarda östrojen yerine koyma tedavisine eklenen farklı simvastatin miktarlarının proksimal femur ve lomber vertebra kemik mineral dansitesi (KMD) üzerine etkisini araştırmak. MATERYAL ve METOT: Kırksekiz tane Wistar Albino cinsi dişi sıçan her biri 8 hayvandan oluşan 6 gruba ayrıldı. İlk 5 gruba ooforektomi, son gruba sham operasyonu yapıldı. Ooforektomi yapılmış 5 grubun 4’üne 120 gün boyunca gavaj yoluyla 150 μg/kg/gün dozunda 17 β-estradiol ve/veya yüksek (6 mg/kg/gün) veya düşük (3 mg/kg/gün) doz simvastatin verildi. Çalışmanın sonunda herbir grubun proksimal femur ve lomber vertebra KMD’si birbiriyle karşılaştırıldı. BULGULAR: Ooforektomi sonrası proksimal femur KMD’si anlamlı oranda azalırken (0.145 ± 0.01 g/cm² ve 159 ± 0.01 g/cm²; p=0.001), lomber vertebradaki kemik kaybının anlamlı olmadığı saptandı (0.161 ± 0.01 g/cm² ve 0.168 ± 0.01 g/cm²; p=0.471). 150 μg/kg/gün 17-β-estradiol tedavisinin proksimal femur ve lomber vertebra KMD’sini koruduğu saptandı. Tek başına 6mg/kg/gün simvastatin ile 150 μg/kg/gün 17-β-estradiol tedavisinin proksimal femur ve lomber vertebra KMD’si üzerine etkisi benzer bulundu. Ooforektomi yapılan sıçanlara kıyasla proksimal femur (0.176 ± 0.01 g/cm² ve 0.145 ± 0.01 g/cm²; p
