ABSTRACT
Objective:
To study the effect of total saponins on cerebral blood flow and vascular resistance in anesthetized dogs.Methods:
Thirty hybrid dogs in either sex,with a body weight of(11?1.5)kg,were evenly randomized into 5 groups negative control group(saline 5 ml/kg,ig),positive control(nimodipine 300?g/kg,iv),and 3 groups treated with total saponins (low-dose group[10 mg/kg,ig],middle-dose group[30 mg/kg,ig],and high-dose group[60 mg/kg,ig]).The dogs were anes- thetized with intravenous pentobarbital sodium(30 mg/kg).The right common carotid artery was exposed to measure the cere- bral blood flow,cerebral vascular resistance,blood pressure and heart rate using the MFV-3200 electromagnetic flow meter and MPA-3000 bioelectricity signal-amplifier.Results:
Compared with negative control,cerebral blood flow was significantly in- creased in animals treated with asparagus root saponins(30 and 60 mg/kg,ig)during 5 and 120 min after drug administration (P
