초록

개 난자의 체외성숙과 체외수정을 통해 수정란을 획득하기 위하여 개 난소를 채취하여 난자의 형태, 난소의 채취시기 등이 체외성숙과 체외수정에 미치는 영향을 구명하기 위하여 수행하였다. 1. 난구세포 부착 및 미부착 난자를 48시간 배양했을 때 체외 성숙율은 $42.0{\pm}3.4%,\;24.4{\pm}4.1%$였다. 난구 세포 부착 난자의 체외 성숙율이 미부착 난자의 체외 성숙율보다 유의하게 높게 나타났다(p>0.05). 2. 난소를 휴지기, 난포기 및 황체기로 구분하여 난자를 회수하여 배양했을 때 체외 성숙율은 각각 35.6%, 50.0%, 31.1%였고 체외 발생율은 각각 2.2%, 20.0% 및 8.9%로서 난구 세포 부착 난자가 미부착 난자에 비해 유의한 체외 수정율을 나타냈다. 3. 난구세포 부착 및 미부착 난자를 이용하여 체외수정시켰을 때 체외 수정율과 체외 발생율은 각각 48.0%, 35.6% 및 22.5%, 13.3%로서 난구세포 부착 난자가 미부착 난자에 비해 유의하게 높게 나타났다.
