Task: Intent Identification
Input (English): To identify injured cells in the liver of patients with primary biliary cirrhosis (PBC) and to determine the effects of ursodeoxycholic acid (UDCA) on these cells, we examined the cellular expression of heat shock proteins (HSPs) in PBC both before and after treatment with UDCA.', 'Expression of HSP70 and ubiquitin in PBC livers (n=34) was evaluated immunohistochemically as well as by immunoblot analysis, and compared with chronic viral hepatitis type C (n= 9), primary sclerosing cholangitis (n=8), and controls (n=7).', 'Immunoblot analysis demonstrated a marked expression of HSP70 and ubiquitin in PBC. Immunohistochemical staining for both HSP70 and ubiquitin was observed to be strong in biliary epithelial cells (BECs) and moderate in both hepatocytes and arteries in PBC. Cellular labelling rates for HSP70 and ubiquitin of bile ducts in PBC were significantly higher (p<0.01) than those in chronic viral hepatitis type C, primary sclerosing cholangitis, or controls. The labelling rates for HSP70 and ubiquitin in bile ducts and in hepatocytes were significantly decreased (p<0.01) after treatment with UDCA in PBC.
