Reperfusion injury is the tissue damage caused when blood supply returns to the tissue after a period of ischemia or lack of oxygen. The absence of oxygen and nutrients from blood during the ischemic period creates a condition in which the restoration of circulation results in inflammation and oxidative damage through the induction of oxidative stress rather than restoration of normal function.

Famous quotes containing the word injury:
“Men have come to speak of the revelation as somewhat long ago given and done, as if God were dead. The injury to faith throttles the preacher; and the goodliest of institutions becomes an uncertain and inarticulate voice.”
—Ralph Waldo Emerson (1803–1882)
