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

Figure 6 Terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling staining and AI. A: Terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) assay results at 48 h partial hepatectomy (× 400 magnification). Many TUNEL-positive cells (arrows) were present in the liver remnant; B: Microphotometric evaluation of apoptosis index (AI) in TUNEL-stained tissue at 48 h after hepatectomy. Values are expressed as mean ± SD. ^aP < 0.05 for comparison between S₁ and control groups; ^cP < 0.05 for comparison between S₂ and S₁ groups. Percentage of TUNEL-positive cells relative to the total cell count was used to estimate AI.
