Gamdutang aqua-acupuncture solution (GAS), Gamdutang water-extracted solution (GWS) and Dae-Gamdutang aqua-acupuncture solution (DGAS) were prepared and tested for antitumor activities. It was shown to possess considerable toxicity toward various tumor cell lines. Concentration of 5 $\times$ and 10$\times$ of GAS resulted in more than 70% inhibition of growth in Ehrlich ascites tumor cells (EATC), Hepa1c1c7 and A549. GAS at concentrations of 5$\times$ and 10$\times$ revealed more than 60% inhibition in HeLa. GWS showed more than 50% inhibition of growth with EATC and HeLa at concentrations of 5$\times$ and 10$\times$, respectively. Toxicity assay with GWS in Hepa1c1c7 and A549 revealed that more than 80% inhibition of growth at the concentration of 5$\times$ and 10$\times$. In morphological study, the number of cells were decreased, and the shape of cells was round-form in EATC, Hepa1c1c7, A549, HeLa with GAS.

Gamdutang aqua-acupuncture solution(GAS), Gamdutang water-extracted solution(GWS) and Degamdutang aqua-acupuncture solution(DGAS) were prepared and tested for potential antitumor activities. It was used three biomarkers (quinone reductase, omithine decarboxylase, glutathione) to test chemopreventive potentials of GAS, GWS, DGAS. GAS was potent inducer of quinone reductase activity in Hepalclc7 murine hepatoma cells in culture, whereas GWS is less potent. GAS, GWS and DGAS were significantly induced quinone reductase activity in cultured rat normal liver cell, Ac2F. Glutathione levels were increased about 1.8-fold with GAS, 1.0-1.1 fold with GWS, DGAS in cultured murine hepatoma hepaiclc7 cells. In addition glutathione s-transferase levels were increased with GAS, GWS and DGAS. The effects of GAS, GWS and DGAS were tested on the growth of Acanthamoeba castellanii. Proliferation of Acanthamoeba castellanii was inhibited by GAS, GWS and DGAS at concentradons of $1{\times}$ and $5{\times}$. These results suggest that GAS has chemopreventive potential by inducing quinone reductase and quinone reductase activities, inhibition of ornithine decarboxylase activity, and increasing glutathione levels.

Gamdutang aqua-acupuncture solution (GAS), Gamdutang water-extracted solution (GWS) and Dae-Gamdutang aqua-acupuncture solution (DGAS) were prepared and tested for chemopreventive potentials. GAS was potent inducer of quinone reductase (QR) activity in Heapa1c1c7 murine hepatoma cells in culture, whereas GWS is less potent. GAS, GWS and DGAS were significantly induced QR activity in cultured rat normal liver cell, Ac2F. Glutathione (GSH) levels were increased about 1.8, 1.0 and 1.1 fold with GAS, GWS and DGAS in Hepa1c1c7 cells, respectively. In addition glutathione S-transferase (GST) activity was increased with GAS, GWS and DGAS. The effects of GAS, GWS and DGAS on the growth of Acanthamoeba castellanii were tested. Proliferation of A. castellanii was inhibited by GAS, GWS and DGAS at concentrations of 1 $\times$ and 5$\times$. These results suggest that GAS has chemopreventive potential by inducing QR and GST activities, increasing GSH levels and inhibition of polyamine metabolism.

Induction of phase II enzymes such as quinone reductase (QR) or glutathione S-transferase (GST) is considered a major mechanism of protection against initiation of carcingenesis. The induction of detoxification enzymes and glutathione were studied with Lonicerae Flos aqua-acupuncture solution (LFAS), Angelicae gigantis Radix aqua-acupuncture solution (AGRAS), and Gamdutang aqua-acupunture solution (GAS) in murine hepatoma cells grown in microtiter plate wells. LFAS, AGRAS and GAS were potent inducers of QR activity. LFAS was induced about 2.6-fold at concentration of $3{\times}$. AGRAS and GAS were also induced about 2.6-, 1.8-fold at concentration of $5{\times}$, respectively. In addition, GST activity was increased with LFAS, AGRAS, and GAS. GSH levels were increased about 2-fold with LFAS at concentration of $5{\times}$, 1.3-fold with AGRAS at concentration of $3{\times}$, and 1.2-fold with GAS at concentration of $5{\times}$. These results suggested that LFAS, AGRAS, and GAS may act as blocking agents against carcinogenesis by induction of phase II marker enzymes.

Concentration of $5{\times}\;and\;10{\times}$ of GAS resulted in more than 70% inhibition of growth in Ehrlich ascites tumor cells(EATC), hepa1c1c7 and A549.

GWS showed more than 50% in hibition of growth with EATC, HeLa at the concentration of $5{\times}\;and\;10{\times}$. Toxicity assay with GWS in hepa1c1c7 and A549 revealed that more than 80% inhibition in growth at the concentration of $5{\times}\;and\;10{\times}$. In morphological study, the number of cells were decreased, and the shape of cells was round-form. Most of cells in detached in EATC, Hepa1c1c7, HeLa, and A549 with GAS. These results suggest that GAS has antitumor activity in vitro.
