Fig. 1. Basic principle of non-enzymic lipid peroxidation involving polyunsaturated fatty acids.

Fig. 2. Simplified scheme of 8-iso-PGF (F2-isoprostanes) formation from arachidonic acid by free radical catalysis. ROS: reactive oxygen species; PGF: prostaglandin F.

Fig. 3. Levels of free 8-iso-prostaglandin F (8-iso-PGF) in plasma and urine at different times after oral administration of CCl4 to rats (2 ml kg-1). ***p<0.001, **p<0.01. [Reprinted with kind permission from Basu, 1999 (25)].

Fig. 4. Upper panel: Mixed venous plasma levels of 8-iso-prostaglandin F (8-iso-PGF) at baseline and after restoration of spontaneous circulation (ROSC). Lower panel: Jugular bulb plasma levels of 8-iso-PGF at baseline and after ROSC.♦: Group ventricular fibrillation (VF) 5; ▪: group VF2; ▴: control group. *: Significant difference versus baseline; §: significant difference between group VF5 versus other groups.
