This work is relationed with the study of the catecholamines and serotonin in the process of adaptation to high altitude. The effects of hypoxia 12.85 O2 in N2 on the pulmonary artery pressure of dogs have been studied, as well as the variations in the levels of Serotonin and Catecholamines in the blood of the same artery. Hypoxia produced pulmonary hypertension in the dogs studied, and at the same time an increase in the level of Serotonin in the blood of the pulmonary artery was produced. The dogs reserpinized had hypertension pulmonary. This result is expounded in relation to a reflex vasoconstriction, which is mediated by Serotonin. Author
