Figure 3. Histological findings of the liver in the reversible obstructive jaundice group, 3 days after clamping the common bile duct. In the reversible obstructive jaundice (ROJ) group, hepatocyte ballooning (upper left, small black arrows) due to ductular (lower left, white arrow) and intracytoplasmic (lower left, white arrowhead) cholestasis was remarkable on day 3. Furthermore, expansion of the portal area due to inflammatory cell infiltration and pseudo bile duct proliferation was notable (upper right, small black arrowheads). Mild lobular inflammation was sporadically identified (lower right).
