Figure 5: A group of female mice injected with oxytocin. The cyanide resistant respiration of liver mitochondria was measured at, 2, 4 and 6 hours after the injection (each measurement take 5 mouse liver). Result shows that the KCN-insensitive respiration is remarkably higher than control at 1 hour after injection, and it is decreased hour by hour, after 6 hours it turn back to normal.
