title: [Studies on metabolic characteristics of cirrhotic rat hepatocytes using primary culture].
abstract: To assess the metabolic characteristics of cirrhotic hepatocytes, a primary culture of hepatocytes was established using rat liver induced cirrhosis by CCl4 administration. Using this system, cell responsiveness to different metabolic and excretory stimuli was investigated and compared with a primary culture of normal healthy rat hepatocytes. Cirrhotic hepatocytes showed reduced protein synthesis in response to insulin and reduced urea synthesis in response to glucagon. However, DNA synthesis stimulated by insulin and EGF was significantly enhanced in cirrhotic hepatocytes. No significant difference was observed in the fluorescein diacetate excretion rate. Cirrhotic hepatocytes showed impairment of antipyrine metabolism and conjugation and excretion of unconjugated bilirubin. These results suggest indirectly that cirrhotic hepatocytes may be less functionally mature than normal healthy hepatocytes.
