Abstract
The effects of tributyltin (TBT), triphenyltin (TPhT) and Aroclor 1254 on germinal vesicle breakdown (GVBD) and ovulation of olive flounder (Paralichthys olivaceus) were investigated in in vitro bioassay. TBT, TPhT and Aroclor 1254 showed the inhibition effects on GVBD and ovulation in response to HCG. The oocyte response appeared to be more sensitive to TBT than Aroclor 1254. TBT was more effective in inhibition GVBD at concentrations of 0.1 and 1 ppm. However, no significant inhibition was obseued in concentrations tested (
성숙 시기의 넙치 (Paralichthys olivaceus) 어미를 대상으로 난 모세포의 GVBD와 배란유도과정에 TBT/TPhT와 Aroclor 1254의 저해효과를 조사한 결과, TBT (또는 TPhT)와 Aroclor 1254모두 GVBD 과정과 HCG로 전처리한 배란유도 과정에 저해효과를 보였으며, 난모세포의 반응은 Aroclor 1254보다는 TBT에 좀 더 민감한 것으로 나타났다. TBT의 처리 농도별 차이는 TBT 0.1과 1 ppm에서 가장 낮은 GVBD 유도율을 보였으나
