Objective:To explore the effects of total saponins of panax ginseng ( TSPG) combined with icariin ( ICA) on learning and memory capability, oxygen free radical and apoptosis of hippocampal CA1 pyramidal cells in vascular dementia ( VD) rats. Meth-ods:The VD rats were obtained by occlusion of bilateral common carotid artery and reperfusion repeatedly combined with intraperitoneal injection of sodium nitroprusside. Spacial learning and memory ability was evaluated by 8-arm radial electric maze test on the 21st day af-ter the drug treatment, the activity of SOD and the level of MDA in the brain were determined, and the adjacent sections were used to de-tect fragmented DNA in apoptotic cells( TUNEL) . Results:The learning and memory ability of the model rats judged by the 8-arm radial electric maze test was significantly decreased compared with that in the sham-operated group (P <0.05). The combination treatment could significantly protect and improve all the evaluated indices of the model rats after the 3-week treatment (P<0. 05) with increased SOD (P<0. 05), and decreased MDA (P<0. 01) and TUNEL positive cells (P<0. 05). Conclusion:The combination drug treatment can significantly protect and improve the spacial learning and memory ability of VD rats, which is related with such effects as improving oxygen free radical metabolism and nerve cell injure in hippocampal CA1 region.

Objective To investigate the effects of exercise on learning and memory after cerebral ischemia. Methods Ninety Sprague-Dawley rats were randomly divided into a sham-operated group, a model group and a treadmill training group ( n=30 for each) , which were further subdivided into groups to receive 7 days, 14 days or 28 days of training with 10 rats in each. The training was treadmill running at 10 m/min for 30 min a day. Cerebral ische-mia was induced in the model and training groups using permanent, bilateral common carotid artery occlusion. The training began three days after the operation. Morris water maze tests were used to measure the rats′ learning and memory ability, and Nissl staining was employed to detect the survival rates of pyramidal neurons in the CA1 area of the hippocampus. Results The average escape latency in the treadmill trained group had shortened significantly by day 7, then further by days 14 and 28. It was significantly shorter than the model group′s average at each time point. The average platform crossing time increased significantly compared with the model group′s average. Few dead neu-rons were observed in the sham-operated group. On days 14 and 28 the average survival rate of pyramidal neurons in the model group was significantly lower than in the treadmill training group or the sham-operated group, though there was no significant difference on day 7. Conclusion Treadmill training can improve learning and memory after cere-bral ischemia, at least in rats. Better effects can be observed after longer training.
