Vagal influence on compensatory ovarian growth is important only briefly after hemicastration.

摘要: Hemicastration induces growth of the remnant ovary in rat. As evidenced by effects total abdominal vagotomy, vagal innervation markedly influences this compensatory ovarian growth. In present experiments, vagotomy inhibited when performed immediately after hemicastration, but not delayed until 4.5 hr hemicastration. Brief exposure subdiaphragmal portion vagi nerves to 2% lidocaine shortly before hemicastration also Fifteen minutes elevated tissue concentrations cyclic adenosine monophosphate (cAMP) were recorded ovaries This accumulation cAMP was that preceded as well pretreatment nerves, and partly followed 10 min At 5 affected vagotomy.
