The effect of (A) 0.1 M NaCl (n = 5), 0.01 M HCl (n = 6), and distilled water (n = 5), and (B) 0.001 M QHCl (n = 5), 0.5 M sucrose (n = 5), and 0.01 M saccharin (n = 5) on the release of histamine in the anterior hypothalamus of freely moving rats [Treesukosol et al. (2005)]. The black bar indicates the 20 min period of taste solution infusion. The mean values of the three baseline samples preceding intraoral infusion were taken as 100%. Values are presented as percentages of the mean basal release ± SEM ^**p < 0.01, ^*p < 0.05 compared with the basal release of each group, respectively.
