The mechanism of collagen synthesis inhibition in cultured human fetal hepatocytes pretreated by salviae miltiorrhizae Bge. (SMB) were studied by determining the concentration of type Ⅲ procollagen (PC Ⅲ ) and malondialdehyde (MDA) in culture medium and hydroxyproline (Hyp) in hepatocytes as well as the activity of glutathione peroxidase (GSH-Px). The collagen synthesis of hepatocytes were stimulated by carbon tetrachloride (CCl4 ) precedently. A significant decrease in production PC Ⅲ, Hyp and MDA. and significant increase in GSH-Px activity were observed in the cultures pretreated with 1 mg/ml of SMB for 4 hours. The results showed that SMB may inhibit collagen synthesis of cultured human fetal hepatocytes stimulated by CCl4.
