The handling of Ca by the rat parotid gland was investigated using
micropuncture, microperfusion, and microanalytical techniques. Concentrations of
Ca were measured in salivary fluid from intercalated, lobular and main ducts, and
net transductal fluxes of Ca and water were calculated during stimulation of
secretion with acetylcholine, pilocarpine, and DLisoproterenol.
