Effect of intraperitoneal injections of 2.5 or 5.0 mg/kg C75 or vehicle (RPMI) on 2-, 4-, and 24-h cumulative food intakes in rats with subdiaphragmatic vagal deafferentations (SDA) or sham operations. The injections were done at dark onset in a crossover design, with 3 days between trials. Each bar represents the mean ± SE of 8 SDA and 8 sham rats. *Less than RPMI in same surgical group P < 0.05; +less than 2.5 mg/kg C75 in the same surgical group, P < 0.05; §difference between effects of RPMI and 5.0 mg/kg C75 in SDA rats larger than in sham rats, P < 0.05.
