| 给5头妊娠54d的山羊每天饲喂黄花棘豆干粉12g/kg体重,试验羊分别于第15,21,22,33d全部流产,而对照组羊全部产下健康羊羔。流产母羊各器官,特别是卵巢和胎盘的病理组织学检查及试验羊的血浆孕酮和17β-雌二醇的放射免疫测定结果表明:卵巢黄体细胞颗粒变性、空泡化和胎盘绒毛膜上皮细胞空泡化,以及妊娠羊血浆孕酮下降。这些变化可能干扰母体对胎儿的营养供应以及毒草的毒素直接作用于胎儿导致流产。 |

| Abstract: |
| Five prognant goats were fed with Oxytropis ochrocephala of 12 g/kg
every day from the 54th day of gestation.These goats aborted respectively in
the 15th,20th,21th,22th and 33th days after ingesting the poisonons plant,
while the control goats produced the health lams.Histopathological changes of
organs from aborted goats,especially ovary and placenta,were examined,and
the level of progesterone and 17β-ecstradiol in the experimental goats were
determined by radioimmunoassy.The results showed that the poisonous plant
could result in granular degeneration and vacuolar degenoration of ovary and placenta in decrease in progosterone.The changes might disturbed the supply of
nutrition from maternal body to fetus,also,the toxin of plant acts on fetus。
A11 of the factors mentioned above might cause goat abortion. |
