Abstract:The study shows that the aqueous extract of Astragalus membranaceus(AMWE) can improve the aniboine-induced impairment on memory acquisition as well as the alcohol-elicited deficit of memory retrieval(number of errorswere reduced and latent period was prolonged) in step down, and can also prolong the gasping duration of mice afterdecapitation at doses of 50g/kg (ig) for 7 days.
