The effect of age on arterial--alveolar nitrogen difference in normal adults.

abstract：:Several studies have utilized the spontaneously hypertensive (SHR) diabetic rat to document the synergistic deleterious consequences of diabetes and hypertension on various organ systems. However, whether these effects are due entirely to the overlapping pathological states or partially result from a greater susceptib...
