[ 1 ] - بررسی نقش استرادیول در همودینامیک ریه به دنبال تهویه با گاز هیپوکسی در موش‌های صحرایی ماده سیروزی شده
زمینه: بیماری‌های کبدی ممکن است به طیف وسیعی از اختلالات ریوی با شیوع بالا در زنان منجر شود. هدف از این مطالعه، بررسی اثر آسیب کبدی به همراه برداشتن تخمدان (اوارکتومی) با و بدون استرادیول بر همودینامیک ریه در زمان تهویه مکانیکی حیوانات با گاز نورموکسی و هیپوکسی بود. مواد و روش‌ها: 40 موش صحرایی ماده نژاد Sprague Dawley به طور تصادفی به 4 گروه اوارکتومی (OVX)، اوارکتومی با تزریق روزانه روغن کنجد...
[ 2 ] - The Role of Anion Exchanger on Pulmonary Vascular Response to Sustained Alveolar Hypoxia in the Isolated Perfused Rabbit Lung
Background: Some respiratory diseases may induce alveolar hypoxia thereby hypoxic pulmonary vasoconstriction (HPV). However, the mechanisms of this physiologic phenomenon are not fully understood. This study was the first to investigate the role of anion exchanger in sustained HPV.Methods: Experiments were performed in the isolated perfused rabbit lung. After preparation, the lungs were divided...
[ 3 ] - Sustained Hypoxic Pulmonary Vasoconstriction in the Isolated Perfused Rat Lung: Effect of α1-adrenergic Receptor Agonist
Background: Alveolar hypoxia induces monophasic pulmonary vasoconstriction in vivo, biphasic vasoconstriction in the isolated pulmonary artery, and controversial responses in the isolated perfused lung. Pulmonary vascular responses to sustained alveolar hypoxia have not been addressed in the isolated perfused rat lung. In this study, we investigated the effect of sustained hypoxic ventilation o...
[ 4 ] - The Interaction between Trolox and 4,4’-diisothiocyanatostilbene-2,2’-disulfonic Acid on Hypoxic Pulmonary Vasoconstriction in the Isolated Rabbit Lung
Background: The mechanism of hypoxic pulmonary vasoconstriction (HPV) is still debatable. It has been proposed that reactive oxygen species (ROS) might be involved in HPV. However, there is no special transporter for superoxide anion in the cell membrane and it may release from the cells via anion exchanger. Therefore, the aim of this study was to investigate the interaction of ROS and anion ex...
