Activity of arginine aminopeptidases and phosphatases in inflamed palatal mucosa in denture stomatitis: a histochemical and biochemical study.

Aminopeptidase and phosphatase activity of denture stomatitis mucosa was studied histochemically and biochemically. Stomatitis clearly increased the activity of these enzymes. An enzyme resembling the chloride-activated aminopeptidase B, usually involved in inflammatory processes, was recognized in the inflamed tissue in higher concentrations than in the control tissue.
