The present study investigated the effect of 24-h continuous ICV infusion of four different tachykinins on the enhanced need-free sodium intake induced by previous repeated sodium depletions in female rats. Female rats were employed because, in response to sodium depletions, they develop a higher need-free sodium intake than male rats. The following tachykinins were used: eledoisin, substance P (SP), [Sar9,Met(O2)11]SP and [Asp5,6,MePhe8]SP(5-11), also referred to as NH2-senktide, all at the same doses of 300 or 600 ng/h x 24 h. Food pellets, water, and 3% NaCl sodium solution were freely available. Eledoisin and NH2-senktide were more potent than SP in reducing the need-free sodium intake. On the other hand, [Sar9,Met(O2)11]SP had no effect. None of the tachykinins employed completely blocked the intake. Water intake was reduced, but this reduction was apparently a consequence of reduced intake of hypertonic sodium chloride solution, because at the same doses TKs did not inhibit water intake in a single-bottle test. Food intake remained unchanged at either dose used. These findings confirm previous studies in which pulse injection of the same drugs potently inhibited sodium intake. They also demonstrate that tachykinins endowed with high affinity for the NK3 receptor are the most potent in inhibiting sodium intake. Furthermore, these findings indicate that the tachykinins reduce the need-free sodium intake only during the infusion period, indicating that in these conditions they do not evoke either aversion for salt, or toxic consequences in the follow-up period.
