Abstract
  1. Propranolol augmented the bronchoconstrictor response to methacholine or histamine, recorded by air overflow in the anaesthetized, vagotomized guinea-pig.2. After adrenalectomy, propranolol was still active, though less so than before.3. In the pithed guinea-pig, there was no augmentation of the effect of bronchoconstrictors on air overflow. The action of propranolol could thus be due to the beta-adrenoceptor blockade of compensatory sympathetic bronchodilator activity, as concluded by McCulloch, Proctor & Rand (1967).4. Electrical stimulation of the thoracic region of the spinal cord of the pithed guinea-pig reduced the effect of bronchoconstrictors on air overflow. This reduction could be blocked by propranolol; practolol was much less effective.
摘要
  1. 在麻醉、迷走神经切断的豚鼠中,通过空气溢出记录发现,普萘洛尔增强了对乙酰甲胆碱或组胺的支气管收缩反应。

  2. 肾上腺切除术后,普萘洛尔仍有活性,尽管比之前活性降低。

  3. 在脊髓损毁的豚鼠中,支气管收缩剂对空气溢出的作用未增强。因此,如麦卡洛赫、普罗克特和兰德(1967年)所总结的,普萘洛尔的作用可能是由于对代偿性交感神经支气管扩张活性的β-肾上腺素能受体阻滞。

  4. 对脊髓损毁的豚鼠脊髓胸段进行电刺激可降低支气管收缩剂对空气溢出的作用。这种降低可被普萘洛尔阻断;心得宁的效果则差得多。
