	n	Crossing platform frequencies	Swimming time in quadrant I(s)	Swimming distance in quadrant I (cm)	Total swimming distance (cm)
Sham operated group	13	11.6±1.7**	16.7±4.3*	102.3±24.5**	2614.6±114.5
Model group	12	3.7±0.8	6.2±1.8	42.7±11.3	2536.7±121.6
MDP group	11	9.4±1.5*	14.3±2.8*	98.8±21.4**	2467.8±153.4

The MWM test was adopted to evaluate learning and memorial capacities of three groups of rats, including navigation test (Table 2) and probing test (Table 3). All values are presented as $\overline{\text{X}}\pm \text{SD}$.
