title: An apparently paradoxical action of aging: decrease of acute hypoxic mortality in male aged rats.
abstract: Mortality of SPF male rats due to hypoxic challenge is less in old than in young rats. This apparent antinomy may be related to a decrease in oxygen consumption because of the relation of volume-surface and, in very old rats (590-700 days old), to a selection process wherby only the hypoxiaresistant rats reach old age.
