Effect of salidroside on learning and memory ability of vascular dementia rats

摘要

The effect of salidroside (SD) on learning and memory ability of vascular dementia (VaD) rats were studied. The Wistar rats were randomly divided into six groups: Sham-operation group, VaD group, positive control (PC) group, SD high dose (SD-HD) treatment group, SD moderate dose (SD-MD) treatment group and SD low dose (SD-LD) treatment group. The bilateral common carotid arteries of Wistar rats were permanently ligated to established VaD models. The special study and memory were observed by Y-maze test. At postoperative 4, 8 and 12 weeks, error number (EN) and total reaction time (TRT) in the VaD, PC, SD-HD, SD-MD and SD-LD group were significantly more than those in the sham- operation group (P0.05). These results suggested that SD could improve the learning and memory ability of VaD rats by different dosages.
