| 摘 要： | 目的 探讨微囊藻毒素LR(MicrocystinsLR,MCLR)对SD孕鼠胎盘的损伤作用.方法 采用整体动物模型观察器官形成期暴露给MCLR对大鼠胎盘的损伤和对宫内胚胎发育的影响.结果 不同剂量的MCLR均可损伤胎盘屏障,在停止注射6天后,仍可造成整个胎盘细胞变性、水肿和间质疏松.结论 MCLR可直接对胎盘产生毒性作用,损伤胎盘屏障并改变其通透性,使得MCLR容易进入胎盘而影响胚胎形成和发育.

| Abstract: | Objective To study the damage effects of Microcystin LR(MCLR)on placenta in Sprague-Dawley rats(SD rats).Methods SD rats were injected with MCLR in their embryo forming period to study the effects of MCLR to the placenta and the embryo development.Results Different dose of MCLR can directly injure the placenta barrier and entered into the embryo,which affected the forming and delopment of embryo.The placenta pathological slices showed that there were degeneration,dropsy and interstitium loosen in all placenta cells on the sixth day stopping injection of MCLR.Conclusion MCLR could injure the placenta barrier directly which made MCLR easily enter the embryo and effect the forming and development of embryo. |
