Tail cuff strain-gauge plethysmograph measure systolic (SBP), diastolic (DBP) heart rate (HR) rats, volunteers, respectively before 0.5, 1.0, 1.5, 2 h post administration. mean arterial (MAP) calculated mathematically SBP DBP. alkaloidal different showed presence variable contents amount active materials. that Arabian, all have potential cause BP lowering effect. Variable antimicrobial activities recorded for when bacteria. Copyright © 2010 John Wiley & Sons, Ltd.
