Abstract :

Semen Ziziphi Spinosae (SZS) has been used as a hypnotic-sedative medicine for thousands of years. Recently, SZS has also shown notable neuroprotective activities via anti-oxidative and anti-inflammatory effects in dementia animals. Jujuboside A (JuA), isolated from SZS, has been proved to be a major hypnotic-sedative component of SZS. In the present study, we firstly evaluated the effects of intracerebroventricular (ICV) injection of JuA (0.02 and 0.2mg/kg) for five consecutive days on cognitive impairment induced by ICV injection of Abeta1-42. The results showed that ICV treatment with JuA significantly mitigated learning and memory impairment in mice induced by Abeta1-42 as measured by the Y-maze, active avoidance and Morris water maze. Furthermore, ICV treatment with JuA reduced the level of Abeta1-42 in hippocampus, significantly inhibited the activities of acetylcholinesterase (AChE) and NO, and decreased the amount of the increased malondialdehyde (MDA) in the hippocampus and cerebral cortex of mice treated with ICV injection of Abeta1-42. Shrinkage of nuclei, swollen and eccentrically dispersed neuronal bodies were observed in hippocampus of AD mice induced by Abeta1-42, however, JuA noticeably improved the histopathological damage. Cumulatively, the present study indicates that JuA may serve as a potential therapeutic agent for the treatment of Alzheimers disease.
