目的观察褪黑激素(MT)对小鼠吗啡戒断反应及血浆、脑组织中NO含量的影响。
Objective: to observe the ultrastructure and synaptic number of cerebral regions related to psychological dependence in rats with different morphine dependent time.
目的：观察不同时程吗啡依赖大鼠心理依赖相关脑区超微结构和突触数量的变化。
Method: Electrical lesions of ventral pallidum were done in 12 morphine dependent rats and the drug seeking behavior was measured by conditioned place preference paradigm.
方法··：毁损依赖大鼠腹侧苍白球，利用条件性位置偏爱实验测定术前、术后依赖大鼠对注射吗啡侧的偏爱程度，评价腹侧苍白球在药物强化效应程度中的作用。
The present study was done both in vivo by cannulating pancreatic duct of morphine dependent rats and in vitro using perfused pancreatic slices from morphine dependent rats.
