项目摘要

Two major studies were conduced in the present project, 1) awake behaving monkey study and 2) anesthetized rat study.1) In order to evaluate the neuronal mechanisms of abnormal pain in the trigeminal region, the effect of N type calcium channel blocker, ONO 2921 was systemically applied to the awake behaving monkeys with capsaicin induced hyperalgesia. The thermal detection task was trained in capsaicin treated monkeys. N type calcium was applied orally or via nasal membrane, and the thermal detection latency was measured. Heat detection latency was significantly elongated after ONO 2921 administration. The elongation of detection latency was slightly longer in oral-administrated monkeys compared with nasal-administrated monkeys. We could not any significant change in detection latency in capsaicin-untreated monkeys after ONO 2921 administration. The present results suggest that ONO 2921 have potent ability to reduce abnormal pain following capsaicin treatment in monkeys.2) The rats' model with inferior orbital nerve injury was studied how the glutamate receptors were involved in the trigeminal neuropathic pain. Rats showed reduction of escape threshold to mechanical stimulation of the face following infra-orbital nerve (ION) injury. We observed significant enhancement of neuronal activity in the trigeminal spinal subnucleus caudalis (Vc) of the rats with ION ligation. After AMPA receptor antagonist CNQX caused significant reduction of neuronal activity in this rat, but not after NMDA receptor antagonist APV or MK801 administration. These suggest that AMAP receptor is involved in trigeminal abnormal pain following trigeminal nerve injury.

在本项目中阐述了两项重大研究，1）醒着的猴子研究和2）麻醉大鼠研究。1）为了评估三叉神经区域中异常疼痛的神经元机制，N型钙通道阻滞剂的效果，Ono 2921的效果已系统地应用于与capsaicia capsaicia capsaicia capsaicia capsaicia capsaicia capsaicia capsaicia capsaicia capsaicia capsaicia capsaicia capsaicia capsaicia capsaicia capsaicia capsaicia capsaicia capsaicia capsaicia sypery capsaicia symenty syno。在经过辣椒素处理的猴子中对热检测任务进行了训练。 N型钙是口服或通过鼻膜施用的，并测量了热检测潜伏期。 ONO 2921给药后，热检测潜伏期显着拉长。与鼻腔给药的猴子相比，口腔给药的猴子的检测潜伏期伸长率略长。 Ono 2921给药后，我们无法在辣椒素未治疗的猴子中发生任何显着变化。目前的结果表明，在猴子中辣椒素治疗后，ONO 2921具有减轻异常疼痛的有效能力。2）研究的大鼠模型具有下轨道神经损伤的模型，研究了谷氨酸受体如何参与三叉神经疗法疼痛。大鼠表现出逃逸阈值的降低，从肌脱落神经（离子）损伤后对面部的机械刺激。我们观察到具有离子连接的大鼠三叉神经核颈肠下核（VC）中神经元活性的显着增强。在AMPA受体拮抗剂CNQX导致该大鼠的神经元活性显着降低，但在NMDA受体拮抗剂APV或MK801给药后，神经元活性显着降低。这些表明，三叉神经损伤后，AMAP受体参与三叉神经异常疼痛。
