Abstract | BACKGROUND/AIMS: METHODOLOGY: Animals were divided into two groups: the control group (n = 8), and the FR-treated group (n = 7) in which FR was administered via the portal vein. While the right portal pedicle was clamped for 60 min, the left portal branch remained patent to avoid splanchnic congestion. Following reperfusion, 75% of the liver (including the right central, quadrate, left central, left lateral, and papillary lobes) was resected. Hepatic venous blood was collected to measure GPT, GOT, and LDH levels. Hepatic tissue blood flow was measured by a laser Doppler flow meter. The liver specimen was harvested for histological study. RESULTS: GPT, GOT, and LDH levels after reperfusion were significantly (P < 0.05) lower in the FR-treated group than in the control group. Hepatic tissue blood flow was maintained significantly (P < 0.05) higher in the FR-treated group than in the control group. Histologically, accumulation of polymorphonuclear neutrophils significantly (P < 0.05) decreased in the FR-treated group compared with the control group. The 2-day survival rate was statistically (P < 0.05) better in the FR-treated group than in the control group. CONCLUSIONS:
FR128998 provides a protective effect for liver parenchyma and sinusoidal endothelial cells during extended liver resection with ischemia.
