In order to prove the antitumor effect of Wekyungtang(WKT) that was originated in Bigeubchunkeumyobang(備急千金要方), Wekyungtang with Houttuyniae Herba(WKT-I) and Wekyungtang with Oldenlandiae diffusae Herba(WKT-II) experimentally, the studies were done, We evaluated the cytotoxic activity against B16- Fo as well as the synergistic effects with anticancer drugs such as cyclophophamide (CPM), cisplatin(CPT) and 5-fluorouracil (5-FU) in vitro and measured body weight, survival time, hematological changes, changes of tissues in G57BL／6 implanted with B16-Fo. The results were obtained as follows: 1. In vitro cytotoxic effect against B16-Fo was shown in all groups as compared with control group, but the concentrations showing inhibitory growth rate below 55% of control was recognized in all concentrations of Wekyungtang(WKT) against B16-Fo and also concentration of $10^4$g／ml above in all group with cyclophophamide (CPM), concentration of $10^3$g／ml in Wekyungtang(WKT-l) with cisplatin(CPT) in synergistic effect, 2. In vivo body and tumor weight were significantly suppressed in all groups as compared with control group 3. The number of platelet, WBC, RBC were significantly increased in all groups, platelet aggregation was significantly increased in WKT-I and WKT-II as compared with control group. 4. In changes of tissues heavy infiltration oh cancer was shown in portal vein, pulmonary tissue, vein, peribronchiole, aveoli, while WKT-I was effective in antihepatic metastasis and WKT-II in pulmonary matastasis. From above results it was concluded that wekyungtang(WKT), wekyungtang with Houttuyniae Herba(WKT-I) and wekyungtang with Oldenlandiae diffusae Herba(WKT -II) had antitumor effect, and also wekyungtang combined with Houttuyniae Herba or Oldenlandiae diffusae Herba were more effective than wekyungtang only and also cyclophophamide (CPM), cisplatin(CPT) showed the more synergistic effect which suggests the necessity of continuous study on the mechanism of antitumor action of Houttuyniae Herba or Oldenlandiae diffusae Herba.

Objectives : Oldenlandiae Diffusae herba has been used as a natural drug for tumor, inflammation and liver disease in traditional medicine. This study was performed in order to investigate the antioxidative effects of Oldenlandiae Diffusae herba methanol extract(ODHM) on acetaminophen induced acute liver injury in mice. Methods : In order to investigate the protective effect of ODHM on acute hepatic injury in vivo, ICR mice were pretreated with ODHM, and then treated with acetaminophen(500mg/kg). And the levels of LPO and glutathione(GSH), antioxidative enzyme activities were measured. The levels of LPO were measured by TBA method. And catalase activity was measured as the decrease in hydrogen peroxide absorbance at 240nm on spectrophotometer using 30mM hydrogen peroxide. Superoxide dismutase(SOD) was assayed by recording the inhibition of nitro blue tetrazolium reduction with xanthine and xanthine oxidase. Glutathione peroxidase(GPX) activity was determined by the modified coupled assay developed by Paglia and Lawrence. The reaction was started by addition of 2.2mM hydrogen peroxide as substrate. The change in absorbance at 340nm was measured for 1min on spectrophotometer. Glutathione-S-transferase(GST) activity was assayed with CDNB as substrate and enzyme activity of GST towards the glutathione conjugation of CDNB. And Total SH and GSH levels were measured. Results : In vivo study, LPO levels of acetaminophen treatment group were significantly higher than other groups. This increased level was significantly reduced by ODHM pretreatment. The acetaminophen treatment resulted in a decrease of catalase, GPX, SOD and GST activities. By contrast, ODHM pretreatment markedly increased compare to those of untreated groups. Total SH and GSH levels were reduced by of acetaminophen treatment, and ODHM pretreatment significantly increased GSH levels.

Objective : This study was designed to investigate the anti-oxidative effects of Oldenlandiae Diffusae Herba Water extract (ODHW) on lipid peroxidation by free radicals oxidative hepatic injury. Methods : In order to evaluate anti-oxidative activities of ODHW in the liver cell, cultured normal rat liver cells(Ac2F) were incubated with or without ODHW. After 16 hours to 18 hours of experiment, cells were placed in DMEM medium without serum, and then incubated with 1mM tert-butyl hydro-peroxide(t-BHP) for two hours. Viable cells were detected by MTT assay. The levels of LPO induced by hydroxyl radical derived from H2O2-Fe2+ system in rat liver homogenate were determined by means of TBA. Inhibitory effect of ODHW on superoxide generation was measured by xanthine-xanthine oxidase system. Results : In the linoleic acid autoxidation system, ODHW exhibited antioxidant activity, which inhibited 85% of linoleic acid peroxidation. These effects were similar to those of dl-a-tocopherol. ODHW showed scavenging effects on DPPH radical, inhibited superoxide generation in xanthine-xanthine oxidase system, and also inhibited lipid peroxidation of rat liver tissue with hydroxyl radical derived from $H_2O_2-Fe^{2+}$ system. In addition, ODHW protected the cell death induced by t-BHP and it significantly increased cell viability in a normal rat liver cell(Ac2F)

The medicinal formula, Kilkyungtang (KKT) and two modified Kilkyungtangs (KKT-1 and KKT-2), which were supplemented by the additional crude drug, Houttuyniae herba (KKT-1), and Oldenlandiae diffusae herba (KKT-2) to KKT, had been applied widely as decoctions for the treatment of malignant tumors. Cytotoxic activities against two tumor cell lines, A549 and $B16-F_0$ were investigated. However, none of them were found to exhibit significant cytotoxicity upon tested tumor cells below the concentration of $1000{\mu}g/ml$. However, cytotoxic activities of three reputed antitumor agents, i.e., mitomycin C (MMC), cisplatin (CPT) and 5-fluorouracil (5-FU) was significantly potentiated by the combined treatment of them with KKT, KKT-1 and KKT-2 respectively, especially against A549 (human non small cell lung adenocarcinoma), in vitro.

The prescription, Kilkyungtang (KKT), which originally consists of twelve kinds of medicinal plant materials and was used as a decoction for the treatment of malignant tumors and two modified Kilkyungtangs (KKT-1 and KKT-2), supplemented by the additional crude drug to KKT (KKT-1:Houttuyniae herba, and KKT-2:Oldenlandiae diffusae herba) were investigated on their antitumoral properties, in vivo respectively. All KKTs were found to exhibit significant life time-prolonging effects when they were administered orally to Sarcoma-180 bearing ICR mice for 7 days. (ILS was estimated as 20% in KKT, 42% in KKT-1 and 57% in KKT-2). A profound lessening of tumor weights was also observed when KKTs were administered to $B16-F_0$ bearing C57B/6 mice.
