本文报告夏天无生物碱可使麻醉犬脑与下肢血流量增加,血管阻力减低(经统计学处理均有显著性差异)、血压轻度下降。提示其有扩张脑血管和下肢血管的作用。并可对抗去甲肾上腺素引起的脑血管与下肢血管的紧张状态。该药不能解除5-羟色胺所产生的脑血管紧张状态。其扩张脑血管作用不被阿托品阻断。
This article reports that in the absence of alkaloids in the summer can increase blood flow to the brain and lower extremities of anesthetized dogs, reduce vascular resistance (significantly different by statistical processing), and decrease blood pressure slightly. It suggests that it has the effect of expanding blood vessels in the brain and lower extremities. It can counteract the tension caused by norepinephrine in the blood vessels of the brain and lower extremities. The drug does not relieve cerebrovascular tension caused by serotonin. Its dilation of cerebrovascular effects is not blocked by atropine.
