Abstract

본 연구는 BPA 및 nicotine 첨가 농도와 배양 시간이 돼지 난자의 체외성숙에 미치는 영향을 조사하였다. $0.02{\sim}10.0mM$ BPA와 $0.5{\sim}10.0mM$ nicotine이 첨가된 TCM-199배양액에서 $40{\sim}52$시간 난자를 배양했을 때 체외성 숙율을 조사하였다. BPA농도가 높을수록 체외성숙율이 유의적으로 낮게 나타났다. $0.05{\sim}10.0nM$ BPA를 첨가한 TCM-199 배양액에서 난자를 44시간 배양했을 때 체외성숙율은 각각 $40.0{\pm}4.1%,\;24.0{\pm}4.7%,\;10.0{\pm}5.3%,\;6.0{\pm}3.2%,\;0.0{\pm}0.0%$로서 첨가 농도가 증가할수록 낮은 체외성숙율을 나타냈다. 난자를 $0.5{\pm}10.0mM$ nicotine를 첨가한 TCM-199 배양액에서 44시간 배양했을 때 체외성숙율은 각각 $44.0{\pm}4.5%,\;24.0{\pm}4.2%,\;18.0{\pm}4.9%,\;8.0{\pm}2.2%,\;0.0{\pm}0.0%$로서 대조군$(52.0{\pm}4.5%)$에 비해 낮은 체외성숙율을 나타냈다. 난자를 0.5 nM BPA와 2.5 mM nicotine을 첨가한 TCM-199에서 $40{\sim}52$시간 배양했을 때 체외성숙율은 $8.3{\pm}2.1%{\sim}26.0{\pm}3.9%$$11.2{\pm}2.2%{\sim}28.6{\pm}3.9%$로서, 44시간 배양이 다른 배양시간보다 가장 높은 체외성숙율을 나타냈다.
