Abstract
  1. Renin-like activity was found in rat submaxillary glands.2. This activity was destroyed by boiling, was non-dialyzable and showed an optimum at approximately 50 degrees C.3. Renin-like activity in the submaxillary gland was not diminished 24 h after nephrectomy but was considerably reduced after ligature of the submaxillary duct.4. Renin-like activity in the submaxillary gland was reduced following food-deprivation, water-deprivation or hypovolemia.5. Renin-like activity in the rat submaxillary gland was increased after isoproterenol administration but not following pilocarpine.6. Renin-like activity in the rat submaxillary gland was increased considerably by administration of NaCl or KCl, as well as following adrenalectomy.7. Chlorothiazide and ouabain increased submaxillary renin-like activity but diazoxide did not affect this activity.
摘要
  1. 在大鼠下颌下腺中发现了肾素样活性。

  2. 这种活性经煮沸后被破坏,不可透析,且在约50摄氏度时表现出最佳活性。

  3. 肾切除术后24小时,下颌下腺中的肾素样活性并未降低,但下颌下腺导管结扎后则显著降低。

  4. 禁食、禁水或血容量减少后,下颌下腺中的肾素样活性降低。

  5. 给予异丙肾上腺素后,大鼠下颌下腺中的肾素样活性增加,但毛果芸香碱给药后则未增加。

  6. 给予氯化钠或氯化钾以及肾上腺切除术后,大鼠下颌下腺中的肾素样活性显著增加。

  7. 氯噻嗪和哇巴因增加了下颌下肾素样活性,但二氮嗪不影响该活性。
