An adaptation of the Lashley cup for use in rat saliva collection.

A miniaturized Lashley cup for collecting rat parotid and submandibular/sublingual saliva is described. The small dimensions of the cup enabled its proper positioning on the orifices of both salivary ducts. The method avoids surgical intervention, causes no tissue damage, allows simultaneous collection of both types of saliva and its appropriate for long-term studies of salivary composition and secretion in the rat.
