Fig. 3.

Thermal stimulation threshold latency (s) that elicited hind-paw withdrawal. The black squares represent saline controls and the black circles represent the ethanol-treated animals. The TNBS-treated animals that recovered without any hypersensitivity are shown as black triangles and the hypersensitive rats are shown as red triangles. All values are means ± standard deviation (see Table 1). The dotted line on the y-axis = 8 s.
