Alteration of Neuropeptides in the Lung Tissue Correlates Brain Death-Induced Neurogenic Edema

NPY was released from the lung tissue of brain-dead pigs, and its concentration was related to the extent of pulmonary edema. NPY may be one of several crucial mediators of neurogenic pulmonary edema, raising the possibility of treatment with NPY-antagonists to increase the number of available lung donors.
