title: Acid hydrolase activity in normal human callus and in psoriatic scales.
abstract: The activities of 14 acid hydrolases have been measured in normal human callus and in psoriatic scales. Values for the scales were much higher than for callus. The increase is believed to be the result of two factors: an increased synthesis of these enzymes by the psoriatic lesion and a diminished degree of inactivation during the keratinization process.
