Abstract

Recordings of electrical activity of the oviduct in conscious ewes fitted with an extracellular multi-electrode assembly confirm the presence of alpha- and beta-adrenergic receptors in both the ampullary and isthmic portions. Regional differences in response to noradrenaline and isoprenaline were observed particularly during oestrus. In all cases the lowest threshold of sensitivity was exhibited by the isthmic portion of the oviduct.

摘要

对装有细胞外多电极组件的清醒母羊输卵管电活动的记录证实，在壶腹部和峡部均存在α和β肾上腺素能受体。尤其在发情期观察到对去甲肾上腺素和异丙肾上腺素反应的区域差异。在所有情况下，输卵管峡部表现出最低的敏感性阈值。
