Do radiographic criteria for emphysema predict physiologic impairment?

abstract：:Endogenously produced oxides of nitrogen appear to play important roles in tissue and organ homeostasis. Endogenous production of nitric oxide, which can be altered in response to various stimuli, can modulate vascular tone, oxyradical cascades, cell adhesion, and other aspects of inflammation. Because exogenously adm...
