Table 1 Food intake during the 4 hours and the 24 hours after an i.c.v. injection of artificial cerebrospinal fluid (CSF, n = 10), 20 μg of L-arginine (ARG, n = 8), 10 ng of interleukin-1β (IL-1β, n = 10), or 20 μg L-arginine followed 2 h later by 10 ng of interleukin-1β (ARG + IL-1β, n = 8)

From: L-arginine abolishes the hypothalamic serotonergic activation induced by central interleukin-1β administration to normal rats
