Malondialdehyde (MDA) concentration in GC and TA 24hours (1day) after reperfusion. The I/R + Ed group, the mean MDA level was lower than in the I/R group. There was a tendency towards lower peroxidation levels observed in the GC samples of the I/R + Ed group, but it was not statistically significant. (p = 0.08) The difference in the TA peroxidation levels however was significantly lower in the I/R + Ed group. (p<0.05).
