Experiment 2: Change in daily food intake (A) and change in body weight (B) in rats after 7 days of infusion of vehicle, leptin (0.1 mg·day⁻¹, s.c.) or leptin (0.1 mg·day⁻¹, s.c.) + SLR (4.3 µg·day⁻¹, i.c.v.). Changes were calculated from average food intake before treatment (control, 16.7 ± 0.8 g; leptin, 17.7 ± 0.5 g; leptin + SLR, 17.1 ± 0.5 g) or from body weight before surgery (control, 309.2 ± 10.8 g; leptin, 312.0 ± 8.5 g; leptin + SLR, 308.3 ± 6.2 g). Values are mean ± SE of seven animals per group. (*) P < 0.05 versus leptin by one-tailed t-test; *P < 0.05, **P < 0.01 versus leptin by two-tailed t-test.
