Plasma amylase after parotid traumatization or duct ligation of male rats.

Parotid traumatization resulted in significant hyperamylasemia at 2 and 18 h, but resolved by 72 h after surgery. Traumatization of the exorbital lacrimal gland did not result in hyperamylasemia. Parotid duct ligation led to significantly increased amylase levels at 24 and 48 h, but resolved by 72 h. [ABSTRACT FROM AUTHOR]
