Abstract
  1. The pressures in the ducts of the parotid and submaxillary glands were recorded in dogs under chloralose-urethane anaesthesia. A single stimulus applied to the parasympathetic nerve regularly caused a pressure rise of short duration. Usually it did not evoke secretion.2. In both glands a single stimulus applied to the vagosympathetic trunk usually caused a pressure response of short duration. It had no secretory effect.3. In the parotid gland, repetitive vagosympathetic stimulation caused a sustained increase of pressure in the duct, usually without inducing secretion.4. In the submaxillary gland, repetitive vagosympathetic stimulation caused a sustained pressure rise, even when the secretory response had been abolished by propranolol.5. It is concluded that the salivary myoepithelial cells of dogs are supplied with fibres from both sympathetic and parasympathetic divisions of the autonomic nervous system and both can cause the cells to contract.
摘要
  1. 在水合氯醛-乌拉坦麻醉下的犬身上记录腮腺和颌下腺导管内的压力。对副交感神经施加单次刺激通常会导致短时间的压力升高。通常不会引起分泌。

  2. 在这两种腺体中,对迷走交感干施加单次刺激通常会引起短时间的压力反应。它没有分泌作用。

  3. 在腮腺中,反复刺激迷走交感神经会导致导管内压力持续升高,通常不会诱导分泌。

  4. 在颌下腺中,反复刺激迷走交感神经会导致压力持续升高,即使分泌反应已被普萘洛尔消除。

  5. 得出的结论是,犬的唾液肌上皮细胞由自主神经系统的交感和副交感分支提供纤维,两者都可导致细胞收缩。
