Mechanisms of Ageing and Development
|September 1, 1985
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.
