Abstract

Abstract: The effect of reperfusion following 30 min of cerebral ischaemia on brain mitochondrial respiratory chain activity has been studied in the gerbil. The state 3 respiration rates with both FAD‐ and NAD‐linked substrates were reduced after ischaemia. After 5 min of reperfusion, state 3 respiration with FAD‐linked substrates was restored, but levels of NAD‐linked substrates did not return to control values until 30 min of reperfusion. By 120 min of reperfusion state 3 respiration decreased relative to control values with all substrates studied. Measurement of the individual respiratory chain complexes showed that complex I, complex II–III, and complex V activities were reduced after ischaemia. By 5 min of reperfusion complex II–III activity was restored, but the activities of complexes I and V did not return to control values until 30 min of reperfusion. In contrast, complex IV activity was unaffected by ischaemia or 5 and 30 min of reperfusion but was significantly reduced after 120 min of reperfusion, possibly owing to free radical production and lipid peroxidation.
