N2 - We investigated the hemodynamic pattern of serum hyaluronic acid (HA) and compared it with that of plasma phosphatidylcholine hydroperoxide (PCOOH) in terms of a convenient parameter of reperfusion injury. Using pig models, we designed two continuous ischemia groups, prepared by blockage of the blood flow at the hepatic hilum for 10 or 30min. A discontinuous ischemia model was prepared by repeating the 10-min ischemia procedure, followed by 10min of reperfusion, to a total ischemia period of 30min. The PCOOH level started to increase just after reperfusion and reached the peak at 90min, followed by a gradual decline after 6h. The HA level increased rapidly in the continuous ischemia groups, starting immediately after ischemia onset until immediately before reperfusion, followed by a gradual decrease during up to 6h of reperfusion. The HA levels in the three groups were almost normalized after 90min of reperfusion, when the PCOOH level reached the peak. These results indicated that the plasma PCOOH level is a useful parameter for predicting the onset and progress of reperfusion injury in its initial stages.
