초록
=목적: 난포생성에서 황체기능의 작용까지 여성생식과정의 여러 단계가 혈관생성에 관련되어 있다. 본 연구는 체외수정을 시행하는 환자에서 혈액 및 난포액내 VEGF (Vascular endothelial growth factor) 농도를 측정하고자 하였다.연구 방법: 2003년 8월부터 2005년 7월까지 본원 불임클리닉에서 체외수정시술을 받은 29명의 환자를 대상으로 하였으며 과배란 유도는 GnRH agonist를 이용한 단기투여법 (short protocol)을 사용하였다. 난자 채취시에 혈액과 난포액을 채취하여 -60℃에서 보관하였다가 효소면역 정량법 (ELISA, enzyme-linked immunosorbent assay)으로 혈청과 난포액의 VEGF 농도를 측정하였다.결과: 총 29명의 환자중 10명의 환자에서 임신이 되었다 (34.5%). 난포액내 VEGF 농도와 혈청내 VEGF 농도 및 연령 사이에는 상관계수 0.428로 유의한 양의 상관관계를 보였고, 난포액내 VEGF 농도와 난포수 및 채취된 난자수 사이에는 상관계수 -0.493로 유의한 음의 상관관계가 나타냈다. 하지만 난포액내 VEGF 농도와 혈청내 VEGF 농도는 상관관계를 보이지 않았다. 대상 여성 중 임신군과 비임신군을 비교하였을 때 난포액내 VEGF 농도는 비임신군에서 1468.38±727.33으로 임신군의 676.48±542.07에 비해 유의하게 높게 나타났다.
