Fig. 1 PGE2 activity (pg/mg protein) at 3, 6, 9 and 24h after drug administration. ASA alone caused a significant decrease in PGE2 at all intervals compared with the control values. Administration of Vitamin E combined with ASA returned PGE2 towards the control values. (***) denotes a P<0.001 (t-test) compared with the corresponding interval of ASA+Vitamin E and the control group.

Fig. 2 Myeloperoxidase (MPO) activity (U/mg protein) at 3, 6, 9 and 24h after the drug administration. Compared with the control values, ASA alone caused a significant increase in MPO at the first three intervals. Administration of Vitamin E combined with ASA returned MPO activity towards the control values. Compared with the control, Vitamin E alone decreased the MPO activity. (*) P<0.05, (**) P<0.01, (***) P<0.001 (t-test). Pathophysiology , DOI: ( /j.pathophys ) Copyright © 2006 Elsevier Ireland Ltd Terms and Conditions

Fig. 3 Superoxide dismutase (SOD) activity (U/mg protein/min) at 3, 6, 9 and 24h after the drug administration. Compared with the control values, ASA alone caused a significant decrease in SOD activity at the all intervals. Administration of Vitamin E combined with ASA increased SOD activity significantly. Vitamin E alone, compared with the ASA+Vitamin E group, increased the SOD activity. (*) P<0.05, (***) P<0.001 (t-test).

Fig. 4 Total glutathione (GSH; nmol/mg protein) at 3, 6, 9 and 24h after the drug administration. Compared with the control values, ASA alone caused a significant decrease in GSH at all intervals. Administration of Vitamin E combined with ASA returned GSH towards the control values. Compared with the control, Vitamin E alone increased the GSH levels at the two first intervals.

Fig. 5 Glutathione peroxidase activity (GSH-px; nmol/min/mg protein) at 3, 6, 9 and 24h after the drug administration. Compared with the control values, ASA alone caused a significant decrease in GSH-px at all intervals. Administration of Vitamin E combined with ASA returned GSH-px towards the control values.
