ABSTRACT
Dioscoreae Bulibferae Rhizoma (RDB) is commonly used in clinical Chinese medicine. It has been used in many kinds of traditional Chinese medicine (TCM), but the toxicity of RDB, easily leads to hepatotoxicity. The objective of the present study is to investigate the synergistic protective effect of Scutellariae Radix (SR) with Phellodendri Chinensis Cortex (PCC) on RDB caused liver toxicity in rats. SD female rats were adopted to establish the hepatotoxicity models by RDB (9 g•kg⁻¹, ig) once daily for 28 consecutive days. After 28 days, liver histological changes were observed, and the activity of transaminase and antioxidant enzymes was evaluated. Morphological and biochemical indicators evaluation showed that, Dioscoreae Bulibferae Rhizoma-induced hepatotoxicity models were successful, and the liver cells were dissolved and swelling with fatty degeneration; inflammatory cells were present in gaps; local punctiformed or lamellar hydropic degeneration was found in liver tissues, with partial necrosis. Indexes of liver function (ALT, AST and ALP) were significantly increased (P<0.05 or P<0.01). The combination of SR and PCC has protective effect on RDB-induced hepatotoxicity in rats. SR+PCC exerted the strongest protective effects against RDB-induced hepatotoxicity. SR, PCC, and SB+CP were observed to exhibit hepatoprotective effect as demonstrated by significant decrease in serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) (P<0.05 or P<0.01), and MAD level in liver tissue (P<0.001), significant increase in GSH content in liver tissue (P<0.001), and significant improvement in his to pathologic changes of liver tissues in rats. SR, PCC and their combinations could achieve liver protection effect by reducing ALT, ALP and AST level in serum, increasing GSH level and anti-oxidantability of liver tissues, and reducing hepatic tissue cells injury.
