Intranasal drug majority contain ephedrine , the drug for vasoconstrictor , hypertension patients , children with caution , atrophic rhinitis were banned 滴鼻药多数都含有麻黄素,此药为血管收缩剂,高血压病人、儿童慎用,有萎缩性鼻炎者禁用。
Typical orienting reactions include dilation of the blood vessels to the brain , slowing of the heart , and constriction of blood vessels to major muscle groups 典型的导向反应包括:通向脑部的血管扩张、心跳减缓、连接主要肌肉群的血管收缩。
Increased levels of circulating caffeine may block adenosine ' s action , causing blood vessels to constrict , subsequently triggering a heart attack , says el - sohemy 血液中咖啡因水平的增加会阻碍腺苷的作用,导致血管收缩,最终则可能导致心脏病发作。
The anion channel blockers niflumic acid ( nfa ) and 5 - nitro - 2 - ( 3 - phenylpropylamino ) - benzoic acid ( nppb ) produced inhibitory effects on ne - evocked contraction in the aorta 主要研究结果: 1阴离子通道阻断剂nfa 、 nppb可以抑制去甲肾上腺素引起的血管收缩。
Norepinephrine ( ne ) - evoked contraction was observed in rat aorta by using routine blood vascular perfusion in vitro . the experimental designs were as follows : 1 本课题利用去甲肾上腺素引起的血管收缩模型,通过常规离体血管灌流技术研究了阴离子通道对血管张力的调节及其机制。
