Brief Summary
The purpose of this study is to explore the impact of aged blood on endothelial function by measuring forearm blood flow during intra-arterial acetylcholine infusion in normal healthy human volunteers after infusion of autologous blood stored for 5-10 days or 35-42 days. Our hypothesis is that 1) the vasodilatory response to the infusion of acetylcholine will be reduced in the 35-42 day group compared with the 5-10 day group, because of scavenging of the NO released from the endothelium by the hemolytic process in the aged blood, 2) that the infusion of aged stored blood will produce vasoconstriction, measured by reduced forearm blood flow during infusion of the 35-42 day compared with the 5-10 day old blood, and that 3) there will be increases in venous levels of cell free plasma hemoglobin, red cell microparticles, red cell membrane damage, arginase levels and activity, decreased arginine levels, markers of oxidative stress (carbamylated proteins and nitrated tyrosine residues), and increases in plasma in vitro NO consumption during the infusion of 35-42 day old compared to 5-10 day old blood.

Outcome Measures
Primary Outcomes (1)
Blood flow response to Acetylcholine.
The primary endpoint will be a comparison of the blood flow responses to the acetylcholine after infusion of 5-10 day old blood compared with the responses after infusion of 35-42 day old blood, each controlled for the opposite arm.
5-10 days vs 35-42 days
Secondary Outcomes (2)
Change in blood flow response to fresh blood (5-10 days) in comparison to aged blood.
5-10 days vs 35-42 days
Comparison in the levels of various biomarkers of aged blood will be examined in venous blood collected from the antecubital vein during the infusion of 5-10 days versus35-42 days old autologous blood.
5-10 days versus 35-42 days
Study Arms (1)
Acetylcholine and Blood
OTHERThis is single arm study. Acetylcholine and blood is infused in brachial artery of non-dominant arm. Blood flow
Interventions
The Acetylcholine solution will be infused intra-arterially at the dosage of 7.5 ug/min for 3 minutes, then 15ug/min for 3 minutes, then 30 ug/min for 3 minutes, after the infusion of normal saline. It will then be infused at 7.5ug/min for 3 minutes, followed by 15ug/min for 3 minutes, followed by 30 ug/min for 3 minutes after the infusion of autologous blood. This will be performed at 5-10 days and 35-42 days of blood storage time.
