石蒜碱

Obserdose of noradrenaline bitartrate or KCl: Sub-maximal constriction of thoracic aorta was induced by 0.1 mmol/L noradrenaline bitartrate or W60 mmol/L KCl, and when constriction curve became stable, DL or nimodipine of different dosage was added.

记录电刺激心室乳头肌时收缩的幅度变化：1次/s，波宽3 ms，阈电压的120％强度电刺激以引发心室乳头肌同步收缩活动，待收缩曲线平稳后，分别用累加法加入二氢石蒜碱或尼莫地平。

RESULTS: Basilar artery, thoracic aorta and ventricular papillary muscle Resting tension of basilar artery was increased by DL but decreased by niof basilar artery and thoracic aorta induced by noradrenaline bitartrate and KCl can be relaxed by DL in a dose dependant manner, and the half-effective concentration was (6.69±3.12)×10-4,(3.41±1.52)×10-3mmol/L for basilar artery, and (1.49±0.59)×10-3,(2.91±0.99)×10-3 mmol/L for thoracic aorta, displaying stronger inhibition on the constriction of basilar artery induced by noradrenaline bitartrate than on the contraction induced by KCl.

重酒石酸去甲肾上腺素、KCl所致基底动脉及胸主动脉收缩，二氢石蒜碱使之呈剂量依赖性松弛，其半数有效浓度值：对基底动脉分别为(6.69±3.12)×10-，(3.41±1.52)×10-3 mmol/L；对胸主动脉分别为(1.49±0.59)×10-3，(2.91±0.99)×10-3 mmol/L。拮抗重酒石酸去甲肾上腺素所致基底动脉收缩作用明显强于KCl。尼莫地平对KCl所致收缩的抑制显著强于对重酒石酸去甲肾上腺素。
