一般认为猪的肺血管对缺氧收缩反应较敏感,但缺氧引起猪的肺动脉增压反应与血组织胺之间的关系尚未见报导。因而。本文用猪作为实验对象,观察急性和慢性间断缺氧时,肺动脉和股动脉血内组织胺含量的变化,试图阐明血组织胺在猪的缺氧性肺动脉压增压反应中的作用。雄性猪15只,体重20～49.5公斤,随意分为两组。甲组(9只)为急性缺氧组。以戍基 It is generally considered that the porcine pulmonary vessels are more sensitive to hypoxia and contractile responses, but the relationship between porcine pulmonary hypertension and hypoxia caused by hypoxia has not yet been reported. thus. In this paper, pigs were used as experimental subjects to observe the changes of histamine content in pulmonary arteries and femoral arteries in acute and chronic intermittent hypoxia in an attempt to elucidate the role of histamine in hypoxic pulmonary hypertension in pigs. Fifteen male pigs weighing 20 to 49.5 kg were randomly divided into two groups. Group A (9) for the acute hypoxia group. To garrison
