Ligation of the parotid ducts induced marked elevation of serum-amylase activity after administration of pilocarpine or isoprenaline. Secretion of saliva and serum-amylase activity increased most rapidly in the first 15 min after injection of pilocarpine, whereas isoprenaline induced a constant rate of secretion and serum-amylase activity over 120 min. Amylase activity in the serum was closely connected with intraductal pressure due to saliva secretion.
腮腺导管结扎后，给予毛果芸香碱或异丙肾上腺素会导致血清淀粉酶活性显著升高。注射毛果芸香碱后的前15分钟内，唾液分泌和血清淀粉酶活性增加最为迅速，而异丙肾上腺素在120分钟内诱导出恒定的分泌速率和血清淀粉酶活性。血清中的淀粉酶活性与唾液分泌引起的导管内压力密切相关。
