The effect of para-chlorophenylalanine on the intake of ethanol and saccharin solutions.
The effects of para-chlorophenylalanine (PCPA) on the ingestive behavior of rats offered a choice between ethanol (3%) and water, saccharin (0.125%) and water, or water alone were examined. Following a baseline period three saline or PCPA injections, 80 mg/kg, were administered. Decreases in both ethanol and saccharin intakes were observed. Increases in water intake occurred in the ethanol group without a change in total fluid intake. Increases in water intake did not occur in the saccharin group and these animals displayed decreases in total fluid intake. Water intake in the nonchoice group was unaffected. There were no changes in food intake associated with any of these effects. The data demonstrate that decreases in intakes following PCPA are not specific to ethanol solutions.
