Abstract

The objective of this study was to investigate the toxic effects of Bisphenol A(BPA) and di-2 ethyhexyl phthalate (DEHP) as endocrine disrupters on sperm motility, viability, membrane integrity and abnormality during in vitro incubation of boar semen. Semen were randomly divide into 24 groups and healed with different concentrations of BPA md DEHP($1{\sim}100{\mu}M$) for 3, 6 and 9 hrs, respectively. The percentages of sperm motility and viability decreased by treatment time with both BPA and DEHP, and obiously differ from the controls. The percentages of sperm motility and viability significantly decreased by incubation with both $100{\mu}M$ of BPA and DEHP compared to control and other treatment groups(p<0.05). Sperm membrane integrity was significantly reduced by incubation with 10 and $100{\mu}M$ of BPA and DEHP, respectively(p<0.05), but sperm abnormality were not significantly affect both BPA and DEHP. These results indicate that high concentration of BPA and DEHP($>10{\mu}M$ can affect noxiously the sperm characteristics.

본 연구는 내분비계 장애물질인 BPA와 DEHP가 돼지 정액 성상(운동성, 생존율, 원형질막의 정상성, 기형율)에 유해한 영향을 미치는지를 검토하였다. 일정 농도로 희석한 돼지 정액에 BPA와 DEHP를 각각 0, 1, 10, $100{\mu}M$의 농도로 처리하여 3, 6, 9시간 동안 체외배양을 실시하였다. BPA 처리에 따른 운동성과 생존율은 체외배양 시간과 첨가농도에 따라 감소하였으며, 체외배양시간이 경과함에 따라 대조구와 명백한 차이를 나타냈다. $100{\mu}M$의 농도로 처리한 경우의 운동성과 생존율은 체외배양시간에 관계없이 처리군이 대조구에 비해 유의적으로 감소하였다(p<0.05). DEHP처리에 따른 정자의 운동성과 생존율도 체외배양시간과 첨가농도에 따라 감소하여 BPA의 성적과 유사한 경향을 나타냈다. 정자 원형질막의 기능성은 배양시간에 따라 감소하였으며 BPA및 DEHP 첨가농도 간에 차이가 인정되었으며, 특히 $100{\mu}M$ 처리구에서 급격히 감소하는 성적을 나타났다. 정자의 기형율은 BPA및 DEHP 처리시간 및 농도에 크게 영향을 받지는 않았다. 본 연구의 결과로 볼 때, 고농도의 BPA와 DEHP($>10{\mu}M$에 정자의 장시간 노출은 유해한 영향을 줄 것으로 사료된다.
