Abstract
Objective: To observe the effects of Uncariae Ramulus Cum Uncis on the conditioned place preference (CPP) induced by morphine in rats. Method : Conditioned place preference was established by morphine sc 15 mg ·kg-1 ·d-1 for 5 d. In the training time
two Uncariae Ramulus Cum Uncis groups (3
9 g ·kg-1
ig) were given Ramulus Uncariae cum Uncis after sc morphine 12 h later daily. The duration of staying in the White Compartment was recorded. Result : The 3 g ·kg-1 group could not influence morphine-dependent CPP; the 9 g ·kg-1 group could extinct to some extent morphine-dependent CPP. Conclusion : The result suggest that Uncariae Ramulus Cum Uncis could extinct to some extent morphine-dependent CPP and has the function of resisting psychological dependence.
