摘要
目的 :观察三叉神经痛发病是否与P物质 (SP)、降钙素基因相关肽 (CGRP)、血管活性肠多肽 (VIP)以及 β内啡肽 ( β EP)有关。 方法 :用放射免疫法检测患者疼痛发作时患侧颈外静脉血、肘静脉血及术后患侧颈外静脉血中SP、CGRP、VIP、β EP含量 ,正常志愿者颈外静脉血中SP、CGRP、VIP、β EP含量作正常对照 ;用免疫组织化学法观察患者痛支与非痛支神经组织中SP、CGRP免疫反应阳性颗粒的差异。结果 :疼痛发作时患侧颈外静脉血中SP、CGRP、VIP含量明显升高 ,患者血浆 β EP含量显著降低 ;痛支神经组织中SP、CGRP免疫反应阳性颗粒的数量、总面积均显著多于、大于非痛支神经组织中的SP、CGRP免疫反应阳性颗粒。结论 :患者体内神经肽的合成或释放异常可能与三叉神经痛的发病有关。
砄bjective: To observe whether substance P(SP), calcitonin gene related peptide(CGRP), vasoactive intestinal polypeptide(VIP),β endorphin(β EP) are related to the pathogenesis of trigeminal neuralgia. Methods: During the attacks of trigeminal neuralgia, SP,CGRP,VIP,β EP in plasma from both external jugular and cubital fossa vein blood ipsilateral to the pain were assessed by sensitive radioimmunoassay in 16 ptients and 10 health controls, after operations the venous blood from the external jugular vein of the patients was sampled again; the external jugular vein blood of normal volunteers was collected as control. SP like and CGRP like immunoreactive positive granules of pain and painless branches were labelled using ABC immunohistochemistry methods; quantitative analysis was performed using HPIAS 1000 system. Results: During the attacks of trigeminal neuralgia, the levels of SP,CGRP,VIP in the external jugular vein blood were significantly higher than those in the cubital fossa vein blood, postoperative external jugular vein blood and the external jugular vein blood of normal volunteers. The plasma levels of β EP in patients with trigeminal neuralgia were significantly lower than that in normal volunteers.The number and area of SP like ,CGRP like immunoreactive positive granules in the pain branches was much more and larger than those in the painless branches . Conclusion: Abnormal synthesis and release of neuropeptides in patients may be related to the pathogenesis of trigeminal neuralgia.
