Only tissue removed from the brain adjacent to the hematoma was studied. Specimens were collected in the operating room; mitochondrial studies were begun within 1-hour. Mitochondrial oxygen consumption was measured after the addition of pyruvate, malate, and ADP, followed by oligomycin and carbonylcyanide.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>\n                      <jats:italic>Results\u2014<\/jats:italic>\n                    <\/jats:bold>\n                    The ICH patients ranged in age from 40 to 54 years; 2 were female and half black.
