	CF, n = 12	TPF, n = 24	TP, n = 12
Weight, g	309 ± 6	315 ± 4	314 ± 6
Food intake before experimental day, g	26.4 ± 0.9	26.4 ± 0.5	26.8 ± 1.1
Percentage of time spent in open arms on the EPM, %	16 ± 3	21 ± 4	14 ± 3
Percentage of entries into open arms on the EPM, %	43 ± 5	42 ± 3	36 ± 6
Total distance moved in the OFT, m	42.7 ± 2.6	47.7 ± 3.1	46.7 ± 4.9

Data are means ± SEMs. There was no significant difference among control with food (CF), tail pinch with food (TPF), and tail pinch without food (TP) groups. EPM elevated plus maze test, OFT open field test (p > 0.05)
