Abstract

The production of pilocarpine-stimulated parotid saliva was evaluated in young adult and aged male and female rats. Parotid salivary flow rate was about 50% lower in aged animals of both sexes. Saliva of aged animals had the same Na+ concentration as that of young rats but contained about 40% more protein. Salivary K+ concentration was similar in young and aged males but not females.

摘要

在年轻成年和老年雄性及雌性大鼠中评估了毛果芸香碱刺激的腮腺唾液分泌情况。两性老年动物的腮腺唾液流速均比年轻动物低约50%。老年动物的唾液中Na+浓度与年轻大鼠相同，但蛋白质含量高出约40%。年轻和老年雄性大鼠唾液中的K+浓度相似，但雌性大鼠不同。
