Abstract

AIM

To evaluate the role of glutamate receptors in the dorsal hippocampus (DH) in the motivational component of morphine withdrawal.

METHODS

NMDA receptor antagonist D-AP5 (5 microg/0.5 microL per side) or AMPA receptor antagonist NBQX (2 microg/0.5 microL per side) was microinjected into DH of rats. Conditioned place aversion (CPA) induced by naloxone-precipitated morphine withdrawal were assessed.

RESULTS

Preconditioning microinjection of D-AP5 or NBQX into the DH impaired the acquisition of CPA in acute morphine-dependent rats. However, intra-DH microinjection of D-AP5 or NBQX after conditioning but before the testing session had no effect on the expression of CPA.

CONCLUSION

Our results suggest that NMDA and AMPA receptors in the dorsal hippocampus are involved in the acquisition, but not in the expression, of the negative motivational components of acute morphine withdrawal in rats.

摘要

目的

评估背侧海马(DH)中的谷氨酸受体在吗啡戒断的动机成分中的作用。

方法

将 NMDA 受体拮抗剂 D-AP5(每侧 5μg/0.5μL)或 AMPA 受体拮抗剂 NBQX(每侧 2μg/0.5μL)微注射到大鼠的 DH 中。评估纳洛酮诱发的吗啡戒断引起的条件性位置厌恶(CPA)。

结果

在急性吗啡依赖大鼠中,预先将 D-AP5 或 NBQX 微注射到 DH 中会损害 CPA 的获得。然而,在条件作用后但在测试阶段之前将 D-AP5 或 NBQX 微注射到 DH 中对 CPA 的表达没有影响。

结论

我们的结果表明,背侧海马中的 NMDA 和 AMPA 受体参与了大鼠急性吗啡戒断的负性动机成分的获得,但不参与其表达。
