Corticosterone serum levels of mice treated with vehicle, Km (10 and 20 mg/kg), and IMI.

Treatment (mg/kg)	Corticosterone Levels (nmol/L)
Naïve	495.42 ± 58.98
Saline solution	891.42 ± 141.13 ***
Km 10	1000.52 ± 38.42 ***
Km 20	1271.51 ± 200.91 ***
IMI 25	925.25 ± 128.59***
	F(4,24) = 4.96, p = 0.05

Effect of the exposure to the pre-test session of the FST in naive (no treatment), vehicle-treated mice, Km (10 and 20 mg/kg; oral route) and IMI (25 mg/kg; i.p. via) treated mice on serum corticosterone levels 24 h after the pre-test. All results are expressed as the average ± S.E.M., of independent groups of eight animals Treatments vs. naive group: *** p ≤ 0.05.
