Abstract

We investigated the effect of oral administration of chlorella prepared from Chlorella pyrenoidosa（Chlorophyceae）at doses of 600 or 1200 mg╱kg on hepatic injuries experimentally induced by D-galactosamine in male rats, an animal model of viral hepatitis. Oral administration of chlorella showed significant improvement on the serum-biochemical and histopathological suppressions in D-galactosamine-induced hepatic injury. In the D-galactosamine-treated rats, chlorella significantly prevented the increases in serum aspartate aminotransferase （GOT）, alanine aminotransferase（GPT）and alkaline phosphatase（ALP）activities in a dose-dependent manner, and also apparently improved hepatic cell necrosis. In addition, the chlorella showed the antagonizing effect on the increase of lipid peroxide and the decrease of triglyceride contents in serum. These findings suggest that oral administration of chlorella may have an ameliorating effect on hepatic dysfunction.
