Figure 1From: Effects of long-term oxygen treatment on α-ketoglutarate dehydrogenase activity and oxidative modifications in mitochondria of the guinea pig heart Effects of 17 h (A) and 60 h (B) oxygenation treatments on bityrosine formation in guinea pig cardiac mitochondria. Values are means ± SE of 5 experiments. **P < 0.01, ***P < 0.001 - significantly different compared with the airtreated group; # P < 0.05, ## P < 0.01 - significantly different when compared with the O2-treated group.Back to article page
