چکیده
Objective(s) Learning is defined as the acquisition of information and skills, while subsequent retention of that information is called memory. The objective of the present study was to investigate the effect of aqueous extract of Boswellia papyrifera on learning and memory paradigms in mice and rats. Materials and Methods This study was held at the Department of Pharmacology, Faculty of Pharmacy, Kermanshah University of Medical Science, Kermanshah, Iran from September ۲۰۰۶ to March ۲۰۰۸. Male Wistar rats and male NMRI mice were randomly divided into control, B. papyrifera treated (۵۰, ۱۰۰, ۱۵۰ mg/kg, p.o.), and piracetam (۱۵۰ mg/kg) groups. Radial arm maze (RAM) and Morris water maze (MWM) were the screening tests used to assess the activity of B. papyrifera extract. Results The mice treated with B. papyrifera (۵۰, ۱۰۰ and ۱۵۰ mg/kg) or piracetam (۱۵۰ mg/kg) showed a decrease in number of days required to learned (P< ۰.۰۵) and time taken to find food by the learned mice in radial arm maze (P< ۰.۰۱). In Morris water maze, rats treated with the above mentioned doses showed dose dependent improvement in spatial learning. Escape latency during swimming in water maze in piracetam and B. papyrifera treated animals was significantly lower (P< ۰.۰۱) than control. Swimming distance was also significantly lower (P< ۰.۰۵) in the treated groups. Conclusion The results show facilitation of spatial learning and memory processes and thereby validate B. papyrifera traditional use of intelligence improving. The presence of alkaloids, flavonoids and saponins might be responsible for this activity of B. papyrifera.کلیدواژه ها
