Metabolism of glycogen in submandibular glands of rats. Alteration by NaF

J Biol Buccale. 1992 Jun;20(2):97-102.

Abstract

Submandibular glands of rats injected with NaF solution (10 mg F-/kg body weight) were analysed for glycogen content and phosphorylase activity after various time intervals. In contrast to what has been reported for the liver, sodium fluoride caused increased glycogen content. Phosphorylase (a and total) activity was not affected, suggesting a different mechanism of action of F- in the submandibular gland. In vivo experiments demonstrated stimulation of glycogenesis.
