| Popis: | To investigate the beneficial effects of inchinkoto (ICKT) in the liver after 70% hepatectomy following ischemia reperfusion.Wistar rats were divided into 3 groups: simple laparotomy and 70% hepatectomy (Hx), 70% hepatectomy following ischemia reperfusion (IR) with vehicle (IRHxV), 70% hepatectomy following IR with ICKT (1 or 2 g/kg of body weight; IRHxK). Vehicle or ICKT was administered for 3 days preoperatively. The hepatoduodenal ligament was clamped for 15 minutes before hepatectomy in the IRHx groups. Rats were killed 1 hours after hepatectomy. In other experiments, the hepatoduodenal ligament was clamped for 30 minutes, with or without ICKT treatment, to evaluate the effect of ICKT on IR injury-induced mortality. Serum transaminase levels and the gene expression of inflammatory cytokines and inducible nitric oxide synthase in the remnant liver were determined. Furthermore, the expression of antioxidant genes was evaluated by PCR array.The elevation of serum transaminase levels, the upregulation of genes for inflammatory cytokines and inducible nitric oxide synthase, and the increased formation of nitrotyrosine observed in the remnant livers of the IRHxV group were all significantly attenuated by preoperative administration of ICKT in the IRHxK group. The expression of antioxidant genes was also higher in the IRHxK group compared with that of the IRHxV group. Moreover, administration of ICKT significantly reduced the mortality induced by IRHx after 30-minute ischemia.Preoperative administration of ICKT provides beneficial effects through attenuating inflammatory responses and oxidative stress in the liver following IR and subsequent hepatectomy. |
