ÖZET
Amaç: Düşük doz oral kontraseptif kullanımının trombosit fonksiyonları üzerine etkilerini araştırmak. Çalışmanın Yapıldığı Yer: Ankara Üniversitesi Tıp Fakültesi Fizyoloji AD. Materyel ve Metod 26-40 yaşlar arasında oral kontraseptif kullanan sağlıklı 7 kadında ve 25-32 yaşlar arasındaki 9 kadından oluşan kontrol grubunda, trombosit sayısı, trombosit agregasyon ve ATP sekresyonu fonksiyonları ölçüldü. İstatistiksel değerlendirme, Mann-Whitney U testi ile yapıldı. Bulgular: Oral kontraseptif kullanan grupla, kontrol grubu arasında trombosit sayıları açısından farklılık bulunmamıştır (p> 0.05). Kollajen ve ADP ile indüklenen trombositlerde maksimum agregasyon şiddeti (MAŞ) ve maksimum agregasyon hızı (MAH), kontrol grubuna göre anlamlı olarak düşük saptanmıştır (p< 0.05). Oysa kollajen ve ADP ile indüklenen trombositlerdeki ATP sekresyonu kontrole göre anlamlı olarak artmış bulunmuştur (p< 0.05). Sonuç: Düşük doz (30 mgr) ethinylestradiol içeren preparatların dahi, 1 yılı aşan sürelerde kullanımı, trombositlerin sekresyon fonksiyonunu artırmaktadır.
