Opiate dependence involves physical and psychical dependence. Although many addicts can bedetoxified, the relapse ratio of 95% in 5 a demonstrates that opiate psychical dependence is aproblem more troublesome. It has been reported that acute and chronic administration of L- NNA canmarkedly retard the development of tolerance to physical dependence on morphine, and suppress theabstinence syndromes precipitated by naloxone in opiate dependent rodents, and even reverse theexisting morphine tolerance. However, the effect of L-NNA on the positive reinforcement ofpsychically active substances and its possible mechanism have not yet been reported. In presentstudy, the effect of L- NNA en the psychical dependence induced by opiates was evaluated on thebasis of conditioned place preference.展开更多
