Abstract:
PURPOSE: Hepatoprotective effect of prostaglandin E1 (PGE1) has been verified in numerous animal experiments but not so apparent in clinical trials. Although the reason for this discrepancy in clinical results is still unknown, one possible explanation is the instability of PGE1. In this study, the hepatoprotective effect of lipo-PGE1, which is known to be stable during pulmonary circulation and have more targeting effect, was investigated in canine partial liver allotansplantation. In order to reckon in the possible injury during harvest of partial liver, lipo-PGE1 was infused from the start of living graft harvest procedure. METHODS: Mongrel dogs weighing about 25 kg were divided into control (n=6) and lipo-PGE1 (n=6) group. Partial liver allotransplantation was performed. In lipo-PGE1 group, lipo-PGE1 was slowly infused through splenic venous cannulation during the donor liver harvesting procedure (50 mg) and continuously infused (60 mg/day) for 48 hrs after reperfusion. The aspartate aminotransferase (AST), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) were monitored. RESULTS: The AST and ALP levels of the lipo-PGE1 group were significantly lower than that of the control group at both 1 hour and 48 hours after reperfusion. The LDH level in lipo-PGE1 group was lower at 1 hour and 48 hours after reperfusion, but no significant differences were shown between two groups. CONCLUSION: This study demonstrated the hepatoprotective effect of the lipo-PGE1 against ischemia-reperfusion injury in canine partial liver allotransplantation.
