Sensitive periods of teratogenic effects of tributyltin on Xenopus tropicalis embryos

  • 摘要: 采用200 ngL-1氯化三丁基锡对热带爪蟾(〖WTBX〗Xenopus tropicalis〖WTBZ〗)胚胎进行第1天、第2天、第3天和3 d全暴露实验.结果表明,第3天和3 d全暴露组胚胎的存活率比对照组分别降低了10%和20%,第2天、第3天和3 d全暴露组的体长分别减少了30%、20%和39%.暴露组胚胎畸形率均在90%以上,畸形类型主要包括眼睛变大、变小或变形、泄殖腔突出、鳍变窄或无鳍和尾巴弯曲等.其中,第2天暴露组胚胎的眼比对照组的小,而第3天暴露组胚胎的眼明显变大;第1天暴露组胚胎的背鳍略有变窄,第2天暴露组胚胎的鳍严重缺失并有尾尖残留或缺刻的现象,第3天暴露组胚胎的背鳍和腹鳍均稍有变窄.由此可见,三丁基锡引起的热带爪蟾胚胎眼和鳍的畸形表现出明显的暴露时段性特征.
