Eur J Oral Sci:正畸怕疼?试试内吗啡肽-2

2019-08-01 不详 网络

内吗啡肽-2在各种疼痛模型中表现出有效的抗伤害作用。本研究旨在探讨内吗啡肽-2在调节大鼠正畸牙齿移动引起的口面部疼痛中的作用。通过结扎螺旋弹簧以模拟正畸力(40g),在雄性Sprague-Dawley大鼠中建立正畸疼痛模型。在正畸牙齿移动后的第0,1,3,5,7和14天,记录咬合力作为正畸疼痛的替代量度。收获同侧三叉神经节,三叉神经尾核和牙周组织用于免疫染色。将内吗啡肽-2,内吗啡肽-2 +纳洛酮

内吗啡肽-2在各种疼痛模型中表现出有效的抗伤害作用。本研究旨在探讨内吗啡肽-2在调节大鼠正畸牙齿移动引起的口面部疼痛中的作用。

通过结扎螺旋弹簧以模拟正畸力(40g),在雄性Sprague-Dawley大鼠中建立正畸疼痛模型。在正畸牙齿移动后的第0,1,3,5,7和14天,记录咬合力作为正畸疼痛的替代量度。收获同侧三叉神经节,三叉神经尾核和牙周组织用于免疫染色。将内吗啡肽-2,内吗啡肽-2 +纳洛酮(非选择性阿片受体拮抗剂),纳洛酮和生理盐水注入三叉神经节和牙周组织,探讨内吗啡肽-2对正畸疼痛的作用。

结果显示,在正畸牙齿移动后,在第1,3,5和7天,三叉神经节中的内吗啡肽-2表达水平升高。在第1,3和5天,正畸疼痛水平增加。内吗啡肽-2的施用进入三叉神经节和牙周组织减轻了正畸疼痛。此外,内吗啡肽-2的作用可能被纳洛酮在三叉神经节中完全阻断,但仅部分在牙周组织中。

因此,内吗啡肽-2在中枢和外周的正畸疼痛调节中起重要作用。
