本文在前段工作的基础上，进一步观察大鼠侧脑室注射促甲状腺素释放激素（TRH）对缺氧性肺血管收缩反应的影响，以探讨中枢TRH在缺氧性肺血管收缩反应中可能起的调控作用。1材料与方法雄性Wistar大鼠36只，体重250～350g，在腹腔麻醉下，分别分离气管、右颈外静脉和一侧股动脉
Based on the previous work, we further observed the effect of TRH injection on hypoxic pulmonary vasoconstriction in rats to explore the possible role of central TRH in hypoxic pulmonary vasoconstriction Regulation. 1 Materials and Methods 36 male Wistar rats, weighing 250 ~ 350g, under abdominal anesthesia were separated trachea, right external jugular vein and femoral artery
