| Abstract: | Objective : To investigate the relationship between the deficit of spatial learning in morphine trained rats and the function of cholingergic system. Methods : Using Morris water maze task; the rats received drug injections(ip)30 min before testing. Results : Morphine (10 mg·kg -1 ) significantly impaired the spatial learning capabilities; co-administration of morphine and scopolamine could aggravate the impairment of acquisition process in rats compared with morphine treatment. Physostigmine could attenuate the impairment of spatial acquisition capabilities induced by morphine administration. Conclusion : Morphine may induce the impairment of the spatial learning and one of the mechanisms is that morphine induces the function of cholingergic system. |
