An acquired coagulation factor X activity deficiency was demonstrated in sheep fed Hymenoxys odorata, bitterweed plant. All coagulation tests were normal before the sheep were given the plant material. All tests involving the function of factor X, including a specific factor assay, became abnormal after the sheep were given bitterweed. Other specific factors remained within normal limits. The presence of an inhibitory activity could not be shown.
在给绵羊喂食臭艾菊（苦草植物）后，发现其出现了后天获得性凝血因子X活性缺乏的情况。在给绵羊喂食这种植物材料之前，所有凝血试验均正常。在给绵羊喂食苦草后，所有涉及因子X功能的试验，包括特定因子测定，都变得异常。其他特定因子仍在正常范围内。未发现抑制活性的存在。
