İneklerde Luteolizis Mekanizması ve Vazoaktif Ajanları

Öz:

Korpus luteum (CL) ovulasyon sonrasında şekillenir ve gebeliğin devamlılığında rol oynar. Ayrıca geçici bir süreprogesteron salgılayan endokrin etkinliği bulunan fonksiyonel bir yapıdır. Sığırlarda luteolizis temel olarak iki fazda meydanagelir. Bunlar fonksiyonel ve yapısal luteolizis olarak sınıflandırılır. Yapısal luteolizis, fonksiyonel luteolizisten CLnin yapısalinvolüsyonu ile ayırt edilebilir. Luteolizis sırasında nitrik oksit, endotelin- I, angiotensin- II ve oksitosin gibi birçok vazoaktif ajanuyarılır. Son yıllarda renkli Doppler ultrasonografi kullanılması ile luteolizis başlangıcında luteal kan akımında artış olduğutespit edilmiştir. Bu derlemenin amacı, Doppler ultrasonografi kullanılarak luteoliziste değişen mekanizmalar, vazoaktifajanların bu süreçteki görevleri ve aralarındaki ilişkiler hakkında bilgi vermektir

Mechanism of Luteolysis and Vasoactive Agents in Cows

Öz:

The corpus luteum (CL) forms after ovulation and plays an important role in the maintenance of pregnancy. Besides,it is a functional structure temporarily secreting progesterone and having endocrine activity. In cattle, the luteolysis generallyoccurs in two phases. These are classified as functional and structural luteolysis. Structural luteolysis is distinguished fromthe structural luteolysis with CL s structural involution. During luteolysis, many vasoactive agents are stimulated such as nitricoxide, endothelin- I, angiotensin II, and oxytocin. In recent years, an increase has been found in the luteal blood flow at thebeginning of the luteolysis, as determined by colour Doppler ultrasonography. The purpose of this review was to explain bothvarious mechanisms about the vasoactive agents responsible in the luteolysis and their reciprocal interactions.
