Cilj rada bilo je ispitivanje efekata eksendina-4 na sindrom policističnih jajnika (PCOS - eng.) kod pacova u uslovima hroničnog blagog stresa. Zbog formiranja modela policističnih jajnika, dehidroepiandrosteron (DHEA) (6 mg / 100 g), sa 0,2 ml susamovog ulja, ubrizgan je potkožno pacovima starim 21 dan (n = 67). Takođe, 0,2 ml susamovog ulja ubrizgano je potkožno i pacovima kojima je data samo injekcija rastvora. Na početku studije pacovi su grupisani u kontrolnu grupu, grupu kojoj je dat samo rastvor, i grupu sa sindromom policističnih jajnika, dok su grupe izložene stresu i eksendinu-4 dodate u drugoj fazi studije. U grupi sa sindromom policističnih jajnika, eksendin-4 dat je pacovima intraperitonalno (10 mg/kg/dan) u uslovima blagog stresa u trajanju od četiri nedelje. Rezultati su pokazali da su težina kao i jutarnje vrednosti glukoze i insulina i nivoi HOMA-IR bili značajno povišeni kod pacova sa sindromom policističnih jajnika nego kod pacova ostalih grupa; takođe, nivoi kortikosterona kod pacova u grupi izloženoj stresu bili su značajno povišeni u poređenju sa pacovima ostalih grupa. Pored toga, štetni efekti sindroma policističnih jajnika na tkivo jajnika evidentirani su prilikom histološkog pregleda. Međutim, nakon primene eksendina-4 na pacovima u grupi sa sindromom policističnih jajnika, težina, jutarnje vrednosti šećera i insulina, kao i nivoi HOMA-IR i LH/FSH bili su smanjeni, dok primena eksendina-4 na pacovima u grupi sa sindromom policističnih jajnika, koji su izlagani stresu, nije bila efektna kao primena eksendina-4 kod pacova sa policističnim jajnicima. Primena eksendina-4 takođe je povećala broj zdravih folikula kod pacova u grupi sa sindromom policističnih jajnika, dok nije bilo nikakvih promena u broju zdravih folikula kod pacova u grupi sa sindromom policističnih jajnika izlaganoj stresu.
