Effect of ursodeoxycholic acid on biochemical parameters, hepatocyte proliferation and liver histology in galactosamine hepatitis in the rat.

The effect of oral administration of ursodeoxycholic acid (UDCA) on biochemical parameters, liver histology and liver cell proliferation was investigated in rats with galactosamine hepatitis. Treatment with UDCA led to a decrease of aminotransferases, but did not show any significant changes in liver histology or liver cell proliferation. The improvement of liver enzymes without change of histology in this animal model of hepatitis following treatment with UDCA is in agreement with results obtained from clinical trials with UDCA in patients with chronic viral hepatitis.
