title: Tumor initiation inhibition through inhibition COX-1 activity of a traditional Korean herbal prescription, Geiji-Bokryung-Hwan, in human hepatocarcinoma cells.
abstract: Some Korean and oriental herbal prescriptions used for a syndrome expressed as chest paralysis and heartache are thought to be effective for angina pectoris. We investigated the effects of an oriental medicinal prescription, Geiji-Bokryung-Hwan (GBH) consisting of herbs of Cinnamomi Ramulus, Poria Cocos Hoelen (Pachymae Fungus), Moutan Cortex Radicis, Paeoniae Radix, and Persicae Semen, on growth-inhibitory activity and cancer chemopreventive activity in assays representing three major stages of carcinogenesis. The GBH was found to act as an potent inhibitor of cyclooxygenase (COX)-1 only but not as COX-2 inhibitor. Furthermore, the extract mediated anti-inflammatory effects and inhibited COX-associated hydroperoxidase functions (anti-promotion activity). Inhibitory effect of the GBH on the growth of cancer cell lines such as HepG2 cell and Hep3B cell was shown. These data suggest that GBH extracts merit investigation as a potential cancer chemopreventive agent in humans, especially in hepatological cancers.
