The effects of acute hypoxemia and hypercapnic acidosis were examined in five unanesthetized dogs in which sodium intake was controlled at 80 mEq/24 hours for 4 days prior to study. Each animal was studied during combined acute hypoxemia and hypercapnic acidosis (Pao2 = 36 +/- 1 mm Hg, Paco2 = 52
The physiological relationship of increased circulating angiotensin II and vasopressin to circulatory changes during combined hypoxemia and hypercapnic acidosis is unclear. To evaluate the role(s) of angiotensin II and vasopressin, seven unanesthetized female mongrel dogs with controlled sodium
Nitric oxide synthase (NOS) catalyzes nitric oxide (NO) formation from L-arginine in the presence of molecular oxygen and NADPH. NO is involved in the regulation of microvasculature. Isosorbide dinitrate (ISDN) and glyceryl trinitrate (GTN) have been widely used as vasodilators to treat acute
Chicken posterior eyecup lined by the retina were prepared, loaded with [(3)H]glycine and superfused in order to determine its release in various experimental conditions. Electrical field stimulation of the retina evoked [(3)H]glycine release with a voltage- and frequency-dependent manner and this
Expression of vascular endothelial growth factor, major endothelial specific glycoprotein growth factor that promotes angiogenesis is regulated at transcriptional, post transcriptional and posttranslational levels. One of the key posttranslational modifications involved in regulating the angiogenic
We studied the effects of angiotensin II (A-II) antagonist, propranolol and prostaglandin F2 alpha (PGF2 alpha) on arterial hypoxemia after injecting autologous muscle to induce massive pulmonary embolism. Twenty-four anesthetized paralyzed dogs were divided into four groups; control, intravenous
Isolated hepatocytes from rat liver in primary culture rapidly lost viability under hypoxic conditions. In the presence of glycine, L-alanine or L-serine loss of viability under hypoxic conditions was greatly retarded. Glycine and L-serine already showed significant protection from hypoxic injury at
