NaCl and LiCl efficacy in the induction of aversion for quinine and saccharin solutions immediately following injection.

Rats 24-hr water deprived were injected IP with a fixed amount (10 ml/kg) of solution of various concentrations of LiCl and NaCl in dosage ranges which in previous experiments either increased or had no effect on water intake. Intake of 0.01% QHCl decreased with increasing concentrations of both NaCl and LiCl. On a molar basis, LiCl was more effeictive. LiCl also produced an aversion to a palatable solution, 0.1% sodium saccharin; however, NaCl produced no aversion over the dosage range which can be tolerated by the animals.
