Difference in Cardiovascular Activities of CPU-86017 between Rat and Rabbit by iv and icv Routes, and Potential Relation to Endothelium

  • 摘要: 目的 研究CPU-86017在大鼠和家兔间心血管作用的差异;观察CPU-86017对大鼠的中枢作用及其对血管内皮细胞的可能作用。方法 iv,icv CPU-86017后,观察大鼠和家兔的血压及ECG。给药前,给药后30min,60min,家兔股静脉取血,每次3mL,置于肝素化试管中,分别测定血浆中NO,NOS,ET及CPU-86017的含量。结果 大鼠iv CPU-86017(3mg/kg)对血压和心跳无显著影响;icv给药出现滞后性低血压反应及早期心率显著减慢。家兔iv CPU-86017(5mg/kg),在给药0,30,60min,收缩压(SBP)显著下降,下降幅度分别为35.4%,25.5%,16.8%,舒张压分别下降48.4%,30.5%,21.9%,心率下降6.9%,16.3%和13.2%,NO、NOS、ET与给药前无显著性差异。结论 CPU-86017对大鼠和家兔的心血管作用存在差异。CPU-86017对心血管系统的作用有中枢作用的参与,其降压作用与血管内皮作用无明显关系。
