Abstract

AbstractAim: To elucidate the anticancer mechanism of Huqi San by assessing the expression of G‐6‐Pase, SDH, ATPase and AFP in N‐nitrosodiethylamine‐mediated hepatocarcinogenesis in rats.Methods: A Solt‐Farber two‐step test model of hepatocarcino genesis was established by diethylnitrosamine (DEN) and 2‐acetylaminofluorene (AAF) in rats to investigate the modifying effects of expression of 6‐glucosephosphatase (G‐6‐Pase), succinodehydrogenase (SDH), adenosine triphosphatase (ATPase) in N‐nitrosodiethylamine‐mediated hepatocarcinogenesis. Hu Qisan compounded by eight medicinal herbs was prepared in glycoprival granules with wich 0.38 g crude herbs/mL solution was prepared for administration. γ‐Glutamy‐transpeptidase (γ‐GT), G‐6‐Pase, SDH and ATPase were immunohistochemically determined. The activity of alpha‐fetoglobulin (AFP) in the livers was measured with Immunofluorescence.Results: Huqi San treated rats showed significant decrease in areas of ‐GT positive foci (P < 0.001). On the other hand, the expression of G‐6‐Pase, SDH and ATPase has obviously altered in Huqi San treated group. The activity of AFP also significantly decreased after the treatment with Huqi San (8 g/kg body weight or 4 g/kg body weight) or total alkali of mistletoe (0.12 g/kg body weight).
