摘要
目的 研究吴茱萸次碱和辣椒素对过敏反应中抗原攻击所致血管收缩的影响。方法 豚鼠腹腔注射牛血清白蛋白预致敏,3周后分离胸主动脉,离体血管环用0.01 mg·mL-1牛血清白蛋白(抗原)攻击诱发血管过敏反应。血管张力变化通过张力换能器连接PowerLab生物信号采集系统连续记录。结果 抗原攻击能诱导豚鼠预致敏的离体胸主动脉收缩,苯海拉明能显著抑制抗原攻击所致的血管收缩;预先用较高浓度辣椒素(1 μmol·L-1)耗竭神经递质降钙素基因相关肽(CGRP)或用选择性CGRP受体拮抗剂CGRP8~37能增强抗原攻击所致缩血管效应;辣椒素(0.03 μmol·L-1或0.1μmol·L-1)促进内源性CGRP释放能显著降低抗原攻击所致血管的收缩效应。吴茱萸次碱(10μmol·L-1或30μmol·L-1)能显著降低抗原攻击所致血管的收缩效应,辣椒素受体阻滞药capsaz-epine和选择性CGRP受体阻滞药CGRP8~37均取消吴茱萸次碱对血管收缩的抑制效应。结论 血管过敏反应时,CGRP的释放增加,能拮抗组胺等物质的缩血管效应;吴茱萸次碱能显著抑制血管过敏反应时血管的收缩,其作用与激活辣椒素受体进而促进内源性CGRP释放有关。
