The total volume, amylase and protein content of cannulated parotid saliva were determined following stimulation with either 5 mg/kg pilocarpine or 5 mg/kg isoproterenol in experimental, pair-fed, and control animals. Saliva from experimental animals was significantly lower in volume, amylase and protein content than both control groups. Sodium dodecyl sulfate, anionic and cationic gel electrophoresis of parotid saliva revealed no qualitative alterations in the types of proteins secreted. 5-fluorouracil treatment reduced the total glandular amylase per unit DNA in both unstimulated and isoproterenol-stimulated parotid glands. Decreased protein synthesis may be the mechanism underlying depleted secretory protein stores since the contents of isolated secretory granules from experimental parotid glands contained less radiolabelled protein than either control group and whole gland homogenates showed marked reductions in the activities of three lysosomal enzymes and total RNA content. Experimental animals contained less labelled protein in their secretory granules than controls, but secreted a greater proportion of their total glandular radiolabelled secretory protein into saliva relative to amylase suggesting that newly synthesized secretory proteins are preferentially secreted.","abstract_html":"Experimental animals were injected intraperitoneally with 100 mg/kg 5-fluorouracil for three days.
