Abstract
  1. The preparation of longitudinal smooth muscle strips from guinea-pig seminal vesicles is described.2. Isoprenaline and salbutamol inhibited contractions produced by parasympathomimetic agents.3. The inhibitory action of isoprenaline was blocked by low concentrations of propranolol and butoxamine. It was concluded that beta(2)-adrenoceptors were present in the tissue.4. The inhibitory action of isoprenaline was not apparent when adrenaline, noradrenaline, hypogastric nerve or transmural stimulation were used to contract the tissue.
摘要
  1. 描述了从豚鼠精囊制备纵向平滑肌条的方法。

  2. 异丙肾上腺素和沙丁胺醇抑制拟副交感神经药引起的收缩。

  3. 低浓度的普萘洛尔和丁氧胺可阻断异丙肾上腺素的抑制作用。由此得出结论,该组织中存在β(2) -肾上腺素能受体。

  4. 当使用肾上腺素、去甲肾上腺素、腹下神经或跨壁刺激使组织收缩时,异丙肾上腺素的抑制作用不明显。
