本文研究了脂氧酶抑制剂枸橼酸乙胺嗪对狗急性缺氧性肺血管收缩反应的影响。实验结果发现静脉注射枸橼酸乙胺嗪后能明显地抑制血管对缺氧的收缩反应。并且,枸橼酸乙胺嗪对狗缺氧性肺血管收缩反应的抑制作用与其应用后所引起的体动脉压下降和心脏功能受抑制等副作用似无关。从而提示白三烯在狗的缺氧性肺血管收缩反应中可能起介导作用。
This article studies the lipoxygenase inhibitor citrate citrate on acute hypoxic pulmonary vasoconstriction in dogs. The experimental results found that intravenous injection of citrate citrate significantly inhibited vascular hypoxic contractile response. Moreover, the inhibitory effect of diethylcarbamate citrate on hypoxic pulmonary vasoconstriction in dogs is not related to the side effects such as the decrease of body arterial pressure and the inhibition of cardiac function after its application. This suggests that leukotrienes may play a mediating role in hypoxic pulmonary vasoconstriction in dogs.
