摘要
目的:研究刺五加叶皂苷(ASS)对麻醉犬器官血流及血管阻力的影响。方法:ASS按7.5、15.0、30.0mg·kg^-1剂量组给麻醉犬静脉输注60min,应用MF-27型电磁流量计测定脑血流量(CBF)、脑血管阻力(CVR)、外周血流量(PBF)、外周血管阻力(PVR)及其血压(SBP、DBP)和心率(HR)等指标。结果:ASS15和30mg·kg^-1剂量组于用药后30minCBF和PBF明显增加,60min达高峰,一直持续至180min,同时CVR和PVR明显降低,ASS7.5mg·kg^-1剂量组CBF、PBF、CVR和PVR均无明显变化。ASS15和30mg·kg^-1剂量组于药后60~180minHR明显减慢,ASS30mg·kg^-1剂量组于用药后30~180min SBP及DBP明显降低,ASS15mg·kg^-1剂量组SBP及DBP有降低趋势,ASS7.5mg·kg^-1剂量组HR、SBP及DBP则无明显变化。结论:ASS对实验性脑缺血的保护作用可能与其明显改善脑循环,增加脑组织血液供应有关。
Objective To study the effect of Acanthopanax senticosus saponins (ASS) on organ blood flow and vascular resistance in anesthetized dogs. Methods The cerebral blood flow (CBF), cerebral vascular resistance (CVR), peripheral blood flow (PBF), peripheral vascular resistance (PVR), blood pressure (SDP and DBP) and heart rate (HR) were measured using the MF-27 electromagnetic flowmeter. Results ASS (15 and 30 mg · kg^-1 iv perfusion for 60 min) augmented CBF and PBF, decreased CVR and PVR within 180 min and slowed down HR at 60--180 min. In addition, ASS (30 mg · kg^-1 iv perfusion for 60 min) could obviously reduce SBP and DBP . Conclusion Protective effect of ASS on experimental cerebral ischemia may he related to improving cerebral circulation and increasing cerebral blood supplyment.
