We used a removable vascular clip for temporary occlusion of the extrahepatic bile duct. The clip was removed on postoperative day (POD) 2. On POD 2, 3, and 5, we measured the hepatocellular injury and metabolic function markers in serum. Activation of mononuclear cells (HIS36) and expression of regeneration markers [cytokeratin 19, hepatic growth factor (HGF)-\u03b1, and HGF-\u03b2] were determined by immunohistochemistry.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"j_iss-2018-0021_s_997_w2aab3b7b3b1b6b1aab1c19b3Aa\">\n                    <jats:title id=\"d5257267e8326_w2aab3b7b3b1b6b1aab1c19b3aAa\">Results<\/jats:title>\n                    <jats:p>The survival rate was 96.67% (1\/30); one animal died.
