The authors paid attention to following the changes occurring in the rabbit after inducing stenosis of abdominal aorta under the branching of renal arteries in acute and chronic experiment: experimentally induced pulmonary edema served as a standard load. In animals with acute induction of the load after performed stenosis of abdominal aorta, there wasn't massive lung edema and the animals usually survived for the pre-set period of 60 min. In the other experimental group, where the lung edema was induced 14 days after the abdominal aorta stenosis, the animals usually died within 35-50 min. although there wasn't any massive exudation of the edema fluid from the tracheal cannula. The animals died from ventricular fibrillation. Adaptation mechanisms of the kidney appear to play some role here.
