摘要:

目的:观察三叉神经痛发作时临近原发病灶的静脉血中是否有血管活性肠肽(VIP) 的参与。方法:用放射免疫法测定16 例三叉神经痛患者,疼痛发作时患侧颈外静脉血、肘静脉血及三叉神经颅底高位切断术后患侧颈外静脉血中VIP 含量,并与11 例正常自愿者颈外静脉血中VIP 的含量比较。结果:疼痛发作时患侧颈外静脉血中的VIP含量明显高于患者肘静脉血、术后患侧颈外静脉血及正常自愿者颈外静脉血中的VIP 含量。结论:三叉神经痛发作时临近原发病灶的静脉血中确有VIP 参与,其作用可能与增强P 物质在局部形成神经源性炎症有关。

Abstract:

The aim of this study was to observe whether vasoactive intestinal polypeptide (VIP) participated in the attack of trigeminal neuralgia , and to understand further its pathogenetic mechanism.Methods :Sixteen patients were studied. During the at2 tacks the venous blood was sampled from both the external jugular vein and cubital fossa vein ipsilateral to the pain , and after op2 erations the venous blood from the external jugular vein was sampled again , the external jugular vein blood of eleven normal volun2 teers was collected as the control. Plasma levels of VIP were determined using sensitive radioimmunoassays.Results :During the at2 tacks of trigeminal neuralgia the levels of VIP in the external jugular vein blood were significantly higher than that in the cubital fossa vein blood , postoperative external jugular vein blood and the external jugular vein blood of normal volunteers.Conclusion : VIP indeed participates in the attack of trigeminal neuralgia in the local region , the role of VIP may be relating to enhancing the effects of substance P in local neurogenic inflammation.
