摘要 目的: 利用电刺激大鼠的偏头痛动物型, 研究与偏头痛病理生理关系密切的 AKAP5 基因在动物型中的表达。方法: 体
重为 250 克左右 SD 大鼠 27 只, 随机分为 a 对照组 (n=4 ) 、 b 电刺激 30 分钟组(n=6)、 c 电刺激 60 分钟组(n=6)、 d 电刺激 120 分钟
组(n=5)和 e 吗啡干预 + 电刺激 120 分钟组(n=6),共 5 组。对照组不予刺激, 其余各组电刺激不同时间, 各组结束后立即断头取脑,
取出延髓及上颈段 (至颈 2 ), 利用 western-blot 技术对 AKAP5 在三叉神经核尾侧复合体中的表达进行研究。 结果: AKAP5 在大鼠
三叉神经核尾侧复合体中有表达, 各组 AKAP5 积分密度比值分别为 2.804, 0.913, 1.383, 0.634, 1.030, 组间表达无显著差异( P=0.
9921> 0.05 )。结论: AKAP5 在电刺激与对照组中的表达无显著差异, 吗啡对 AKAP5 的表达无显著影响。 |

ABSTRACT Objective:To investigate the molecular mechanism of migraine by studying the gene expression of AKAP5 in animal
model. Methods:27 rats were randomly divided into five groups including control group (n=4), groups of electrical stimulation for 30
minutes (n=6), 60 minutes (n=6), 120 minutes (n=5) and group of morphine plus electrical stimulation for 120 minutes (n=6). Rats were
rapidly decapitated, and the medulla and high-level cervical cord (to C2) were removed from the skull after electrical stimulation. Results:AKAP5
was detected in the medulla and high-level cervical cord by western blot technique. AKAP5 expressed in the bulb and high cervical cord. The integral optical density ratios of AKAP5 were 2.804 0.913 1.383 0.634 and 1.030 respectively. There were no significant
deviation for AKAP5 expression among the five groups ( P=0.9921> 0.05 ) .Conclusion: There was no significant deviation for AKAP5
expression between control and electrical stimulation groups. Morphine had no effect on AKAP5 gene expression. |
