Abstract
AIM: To investigate the dynamic changes and the relationship between intestinal endotoxemia (IETM) and liver regeneration after partial hepatectomy (PH) in rats.
METHODS: Wistar rats were randomly divided into three groups: normal control (NC) group, sham operation (SO) group and PH group. Levels of endotoxin (ET) in blood were measured in rats of each group 6, 12, 24, 36, 48, 72, 120 and 168 h after PH, respectively. Liver regeneration was evaluated by different methods.
RESULTS: Plasma endotoxin level was increased in PH group during 6-72 h after PH, and the levels appeared at 12 and 48 h were significantly higher than those at the corresponding time point in NC and SO groups (12 h: P = 0.002 < 0.01 vs NC, SO; 48 h: P = 0.002 < 0.01 vs NC, P = 0.000 < 0.01 vs SO). However, ET returned to normal level after 72 h. After PH, the weight of remnant liver, the rate of liver regeneration, the percent of S phase liver cells and the index of PCNA in liver were increased significantly, but there was no relationship between these data and plasma ET. In NC and SO groups, liver regeneration showed no significant difference between the different time points.
CONCLUSION: There is no relationship between IETM and liver regeneration after PH, suggesting that IETM has no direct effects on liver regeneration.
