Hyperbaric oxygenation promotes regeneration of biliary cells and improves cholestasis in rats

Figure 3 Percentage of proliferating cell nuclear antigen-positive cells in both groups at 24, 48, 72 and 96 h after hepatectomy. A: The percentage of proliferating cell nuclear antigen (PCNA)-positive hepatocytes was higher at 48 and 72 h and lower at 24 h in the hyperbaric oxygenation (HBO) group than in the control group. The percentage of PCNA-positive biliary ductal cells in the HBO group was higher at 48 h compared with the control group; B: The proliferation of biliary ductal cells was increased in the HBO group, with an early peak at 48 h. Results are expressed as mean ± SD of n = 6 for each period in each group. ^aP < 0.05, ^bP < 0.01.
