Abstract:
Objective To observe the effect of cistanche deserticola polysaccharides on learning and memory ability of different types of spatial learning and memory abilities in micey.Methods The 120 mice were randomly divided into blank group, model group, Cistanche deserticola polysaccharide, low and medium dose group, and Lacita group, 20 rats in each group. The low, medium and large dosage groups were given 25, 50 and 100 mg/kg Cistanche deserticola polysaccharides, piracetam group was given 10 mg/kg Laci Staw, blank group and model group were given 10 mg/kg volume distilled water. Continuous administration for 6 weeks. Cicloheximide mice were used to consolidate memory impairment model, using ethanol to establish a model with reappearance of memory disorders. The ability of learning and memory in water maze test in mice, the mice were detected in the brain of total protein, MDA, SOD.Results Compared with model group, the escape latency (9.45 ± 2.86 s, 12.73 ± 10.89 svs. 48.15 ± 30.33 s), and the first time arrived at the station (19.33 ± 3.27 s, 13.81 ± 9.79 svs. 40.71 ± 16.76 s) was the median, large dose group were significantly shortened (P<0.05); the first time to reach the site (11.58 ± 7.04 svs. 40.71 ± 16.76 s) in the low dose group was significantly shortened (P<0.05), the number of crossing the platform (5.46 ± 2.09vs. 3.03 ± 1.47) in the low dose group significantly increased (P<0.05); the total protein content in brain tissue (0.76 ± 0.25 g/Lvs. 0.55 ± 0.12 g/L) in the high dose group significantly increased (P<0.05). Compared with the ethanol model group, the escape latency (22.67 ± 18.35 s, 22.15 ± 16.22 s, 18.00 ± 13.44 svs. 51.33 ± 22.19 s), the first time arrived at the station (16.70 ± 11.25 s, 19.75 ± 14.62 s, 9.47 ± 5.46 svs. 30.09 ± 13.63 s) in the low, medium and high dose group were significantly shortened (P<0.05), crossing the target (5.15 ± 1.28, 4.83 ± 0.75vs. 1.34 ± 0.83) in the low, medium and high dose group were significantly increased (P<0.05).Conclusions Cistanche polysaccharide could significantly improve the reproducibility of memory impairment in mice.
