Portal inflow preservation during portal diversion in small-for-size syndrome

Figure 5 Liver regeneration and apoptosis. A: Percentage increase in liver remnant weights; B: Proliferating cell nuclear antigen (PCNA) staining of liver remnant (positive cells are indicated by arrows; × 400 magnification); C: Microphotometric evaluation of PCNA index in PCNA-stained tissue 48 h partial hepatectomy. Values are expressed as mean ± SD; n = 6 in both groups. D: Thymidine kinase (TK) activity. ^aP < 0.05 for comparison between S₁ and control groups; ^cP < 0.05 for comparison between S₂ and S₁ groups. PI was used to quantify hepatic regeneration. PCNA data were expressed as the percentage of PCNA-stained hepatocytes per total number of hepatocytes.
