用，深化癫痫的发病机制。方法：本研究采用海人酸腹腔注射诱发大鼠癫痫发作，并分别于癫痫终止后8 小时、1、3、7 天和慢性复
发时间点行免疫组化方法检测prepro-orexin 免疫反应阳性细胞数及其神经纤维的变化情况。结果：prepro-orexin 免疫阳性细胞
的分布主要在外侧下丘脑和穹窿周围核，在海马、大脑皮层及其他大脑组织中并未检测到，各组之间prepro-orexin 阳性细胞数进
行方差分析表明其差异并不显著，P>0.05；而其免疫阳性神经纤维主要分布在下丘脑、丘脑室旁核及海马，数量稀少；结论：大鼠致
痫后，随着时间的推移，prepro-orexin 免疫阳性细胞总体减少，但未具有统计学意义，但并不能完全认为其与癫痫发作无关；而其
免疫反应神经纤维稀少。 |

| Objective: To investigate the changes of the prepro-orexin and its nerve fibers in the rat epilepsy model at different
time points. Methods: Seizures were induced by intraperitoneal injection of kainic acid. The changes of the prepro-orexin
immunoreactive cells and nerve fibers were detected by immunohistochemistry at 8 hours,1,3,7 days and chronic relapsing time after the
termination of epilepsy respectively. Results: Prepro-orexin immunoreactive cells distributed mainly in the hypothalamus and perifornical
nuclei, and were not detected in the hippocampus, cerebral cortex and other brain tissues. Its immunoreactive nerve fibers distributed
sparsely in the hypothalamus paraventricular thalamic nucleus and the hippocampus; Conclusion: The overall reduction of the
prepro-orexin immunoreactive cells is not statistically significant,but can't be fully considerde that they have nothing to do with the
seizure. And their immunoreactive fibers distribut sparsely. |
