ANF may increase peripheral vascular permeability without pulmonary effects in rats; hypothesis-generating for organ-specific permeability in heart failure models.
Does atrial natriuretic factor infusion alter albumin escape in specific organs in anesthetized, splenectomized, anephric rats?
At pathophysiological levels, ANF increases pulmonary albumin escape potentially contributing to pulmonary edema, whereas pharmacological levels may protect the lungs by preventing increased pulmonary albumin escape.
Zimmerman et al. (1990) studied this question.
