title: Serum squalene levels in hepatobiliary diseases.
abstract: Serum squalene levels did not change in patients with acute hepatitis, chronic active hepatitis and liver cirrhosis, but were significantly reduced in patients with intra- and extrahepatic cholestasis. The ratio of cholesterol to squalene remained normal in patients with acute hepatitis as well as chronic active hepatitis, while being slightly decreased in patients with liver cirrhosis. On the other hand, in patients with cholestasis the ratio was markedly raised. From these observations we confirmed abnormal sterol metabolism in hepatobiliary diseases, and clinical usefulness of the ratio of cholesterol to squalene to distinguish hepatocellular injury and cholestasis.
