Open Access Abstract Introduction Epithelial corrective and destructive mechanisms have not been studied in inflammatory gallbladder disease. Methods Epithelial apoptosis cell proliferation and expression of hypoxia-inducible factor HIF -1a were compared in gallbladders from patients with acute acalculous cholecystitis AAC n 30 and acute calculous cholecystitis ACC n 21 and from patients undergoing surgery for other reasons normal gallbladders n 9 which were removed during open cholecystectomy. The immunohistochemical stains included antibodies to Ki-67 proliferation M30 apoptosis and HIF-1a. Proliferation and apoptosis were expressed as percentages of positive cells. HIF-1a expression was expressed as .
