Preimplantation mouse embryos were exposed to ricin, a plant toxin, in vitro and in vivo. The effect was evaluated by morphological observations of the exposed embryos as well as by means of protein synthesis. Ricin was highly toxic to the preimplantation mouse embryo in vitro, the effect being greater on the 2-cell than on the 4-8 cell stage. Intraperitoneal injection of ricin induced a small number of fetuses with exencephaly.
将植入前的小鼠胚胎在体外和体内暴露于蓖麻毒素(一种植物毒素)。通过对暴露胚胎的形态学观察以及蛋白质合成方法来评估其效果。蓖麻毒素在体外对植入前的小鼠胚胎具有高度毒性,对2细胞期胚胎的影响大于对4 - 8细胞期胚胎的影响。腹腔注射蓖麻毒素会导致少数胎儿出现无脑畸形。
