Figure 1

Tumour necrosis factor (TNF)-α concentrations in plasma of male swine achieving return of spontaneous circulation (ROSC), versus time. Time 0 = pre-arrest, i.e. control value; time intervals after 0 represent time from ROSC. Large boxes with error bars represent mean and standard deviation for the group. TNF-α levels at 15, 30 and 60 min were significantly greater than control values. After 60 min, levels were not significantly different from pre-arrest values.
