Urinary Erythropoletin in Men Subjected to Acute Hypoxia.

Abstract

SummaryThe urinary erythropoietin content of residents at sea level, were measured during a 5-day sojourn at 14,900 feet. We found an early EP rise with the peak on the 2nd-3rd day of exposure. Thereafter, activity declined. The rapid increase in activity is considered to reflect the response to a severe hy-poxic stimulus, and the subsequent decrease.
