[Functional morphology of the submandibular salivary glands of white rats during aging involution].
Functional morphology of different zones of submandibular glands of albino rats was studied quantitatively with due regard for the stages of neuroendocrine system involution. It is shown that function of salivary glands during ageing is not altered; cyclic fluctuations with estral cycle phases are maintained similarly to those in young animals. But the basal level of proteins and mucopolysaccharides is reduced, their mean levels being equal to the minimal level in young animals. On the other hand, activation of enzymes responsible for energy and transport processes takes place and their relationships change. The data obtained prove the relationship between salivary and endocrine glands and confirm the viewpoint that in early age involution disintegration occurs between different parameters of the functional activity of salivary glands rather than there take place changes in their function.
