The body weight, open-field test and sucrose consumption test in the two groups rats after modeling (n = 20, mean ± SEM).

	Body weight (g)	Open field test			Sucrose consumption
		Horizontal score	Vertical score	Total score	Sucrose (g)	Total (g)	Sucrose preference (%)
Control	306.34 ± 7.2	37.3 ± 3.96	14.5 ± 2.03	51.8 ± 5.47	9.2 ± 0.87	12.74 ± 0.99	71.9 ± 2.6
CUMS	268.86 ± 4.88**	16.9 ± 1.35**	7.9 ± 1.32*	24.8 ± 1.50**	5.6 ± 0.40**	8.76 ± 0.68**	64.1 ± 2.2*

CUMS produced a significant decrease in the body weight, horizontal and vertical exploratory locomotor activity, sucrose intake and sucrose preference in the CUMS rats compared to that in the control rats (

^*p < 0.05,

^**p < 0.01).
