- Then adrenalin and Fructus Lycii extract were added into the bath solution,and the tension of thoracic aortic rings was recorded. 结果:肾上腺素能迅速升高离体大鼠胸主动脉张力,并维持于一定水平,而枸杞子提取物能缓慢地降低离体大鼠胸主动脉张力。
- These data demonstrated that MBH derivatives XY9902 and XY9905 had vascular relaxation effect on rat aorta rings in vitro . 苯并二氢吡喃腙衍生物 XY990 2、XY990 5对离体大鼠主动脉环有舒张作用
- Caffeic acid and ferulic acid were shown to increase the mouse survival time induced by ET 1 iv administration and decrease the vasoconstrictions of isolated aortic rings. 咖啡酸和阿魏酸(ip) 能剂量依赖性地显著延长ET?1 致小鼠急性死亡时间,在离体器官可观察到咖啡酸与阿魏酸能拮抗ET?1的缩血管效应;
- Taurine itself showed no effect, but enhanced the relaxation of Ach and Ami, and antagonized the contraction of Iso on aortic rings of female rats aged 3 months. 牛磺酸对3月龄雌性大鼠主动脉几无作用，但可显著增加Ach、Ami的舒血管作用，拮抗Iso的缩血管作用，80 mmol/L牛磺酸效应最佳。
- When the aorta rings were incubated with Cic and Bep, a potentialized inhibitory effect was observed on KCh but not NE-induced contractions. Bep主要抑制KCl激动的主动脉环收缩。 Cic与Bep联孵时,Cic可增加Bep抑制NE激动主动脉环收缩的效应;
- Agm also relaxed aortic rings in a concentration dependent manner under the condition of precontraction induced by CaCl 2 at a concentration of 3 mmol/L. 在高Ca2 +(3mmol/L)引起血管预收缩的基础上 ,Agm也可剂量依赖性地舒张大鼠主动脉。
- The effects of D-polymannuronic sulfate (DPS) on the norepinephrine (NA) or potassium chloride (KCL)-induced contraction of rat aortic rings were studied in this paper. 本文观察了海洋硫酸多糖DPS对去甲肾上腺素（NA）和氯化钾（KCl）所致大鼠主动脉环收缩反应的影响。
