Exemplary brain slices of gelatinase-activity measurement in different ROIs are shown. Higher fluorescence intensity could be observed in group Co and group T. Hypothermia reduces gelatinase activity. Reduction of activity is most prominently in the area of the hippocampus. BG:Basal ganglia; Kx: Cortex; Hi: Hippocampus CA1-region. Bar: 50 μM.
