Amylase levels in the tissues and body fluids of several primate species.

1. Serum amylase levels in the gorilla, orang-utan, chimpanzee and squirrel monkey are similar to man. Serum amylase in the Rhesus macaque is almost a whole order of magnitude higher than man. 2. Of the several species tested, all have appreciable amylase in saliva or the parotid gland except the squirrel monkey. 3. High levels of amylase were found in the pancreas of all species tested. Amylase was found in the livers of all species tested. 4. In in vivo experiments with squirrel monkeys, injection of puromycin did not alter serum amylase levels.
