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.

• kg-1剂量组给麻醉犬静脉输注60 min；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:ASS 15和30 mg.
