Strips of rumen wall from bovine fetuses were incubated in an organ bath with prostaglandin F2 alpha (0.13 to 33.76 microgram/ml). The highest reactivity with a submaximal dose (17.03 microgram/ml) was observed in the period between 3.0 and 7.9 months of fetal age. A smaller response, but higher than in 1.0 to 2.9 months old fetuses, was observed in the 8.0 to 8.9 months fetuses. The period of the highest reactivity to prostaglandin F2 alpha coincides with the age of onset of papillary morphogenesis and the period of highest reactivity to autonomic and putative transmitter drugs.
将来自牛胎儿的瘤胃壁条带置于含有前列腺素F2α（0.13至33.76微克/毫升）的器官浴中进行孵育。在胎儿3.0至7.9月龄期间，观察到对次最大剂量（17.03微克/毫升）的反应性最高。在8.0至8.9月龄的胎儿中观察到反应较小，但高于1.0至2.9月龄的胎儿。对前列腺素F2α反应性最高的时期与乳头形态发生开始的年龄以及对自主神经和假定递质药物反应性最高的时期一致。
