The purpose of this study was to elucidate the effect of Oldenlandiae herba and Houttuyniae cordata on calf diarrhea in farms. We examined the antibacterial and antiviral effect of Oldenlandiae herba and Houttuyniae cordata extracts in vitro. And we divided diarrheal calves into three roups in farm; Oldenlandiae herba administration group(10 calves), Oldenlandiae herba and Houttuyniae cordata administration group(10 calves) and control group(7 calves). We estimated the therapeutic effect of the calf diarrhea by using clinical signs, CBC, AST, BUN, creatinine, and measurement of lymphocyte distribution in whole blood. Oldenlandiae herba and Houttuyniae cordata extracts by ethanol(98%) had antibacterial and antiviral effect. In the condition of diarrhea, the fecal condition of Oldenlandiae herba and Houttuyniae cordata group was relieved more than that of others group during experimental period. PCV and fibrinogen concentrations were high in control group. AST and BUN were within normal range in all groups. Administration of Oldenlandiae herba and Houttuyniae cordata was not toxic to the liver and kidney. And Oldenlandiae herba and Houttuyniae cordata extracts also affected the lymphocytes distribution in blood. From these results, we suggested that administration of Oldenlandiae herba and Houttuyniae cordata should be effective on the dairy calf diarrhea in farms.

For the evaluation of anti-tumor activity of Korean Oldenlandia Herb (KOH) and Radix (KOR), our experiment was performed with methanol extracts of KOH and KOR. They did not shown any cytotoxicity against HT1080 cell lines. However, they effectively showed anti-metastatic activity through inhibition of the adhesion of HT1080 cells to gelatin, downregulated the expression of MMP2 and uPA and upregulated the expression of TIMP2. They also inhibited tube formation of HUVECs induced by bFGF. However, they did not affect DNA topoisomerase I activity. Simiarly, the T/Cs % in KOH and KOR treated mice were increased 134.9% and 171 %, respectively at 2500 mg/kg. These results suggest that KOH and KOR exert anti-tumor activity via anti-metastatic and anti-angiogenic activities. The further study for isolation of effective compounds and its exact mechanism and comparative study with Chinese Oldenlandia Herba will be required.

Oldenlandia diffusa, Cremastra appendiculata and Fritillaria thunbergii are widely distributed in the Korea, China and Japan, and has been used in traditional medicine for various diseases, such as pharyngolaryngitis, tonsillitis, goiter and stomach ulcer. However, the anti-cancer activities in human breast cancer have not been clearly elucidated yet. In this study, it was compared the in vitro cytotoxic effects of single and complex treatment of O. diffusa, C. appendiculata and F. thunbergii. We treat human breast cancer MCF-7 cells with O. diffusa, C. appendiculata and F. thunbergii. And we evaluated viability, growth inhibition, morphological changes, apoptotic bodies formation, measurement of the cell cycle and formation of DNA fragmentation of these cells. It was found that single treatment of O. diffusa could inhibit the cell proliferation in human breast cancer MCF-7 cells. However, complex treatment of O. diffusa, C. appendiculata and F. thunbergii is weakly or not affect the cell proliferation of MCF-7 cells. And anti-proliferative effects of O. diffusa in MCF-7 cells was associated with G1 arrest of cell cycle. These findings suggest that O. diffusa may be a potential chemotherapeutic agent for the control of human breast cancer cells and further studies will be needed to identify the molecular mechanisms.

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)

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.

Oldenlandiae Herba has been used for the prevention or treatment of cancer in oriental medicine for years. Experimentally its antitumor activity was reported. However, in order to develop new Korean original plants. we tried to study the antitumor activity of Chinese and Korean origin Oldenlandiae Herba. We first evaluated the cytotoxicity of Oldenlandiae Herba originated from China and Korea on HT1080, U937 and SK-mel tumor cells. MeOH extract of Chinese Oldelandiae Herba was more effective than MeOH extract of Korean Oldenlandiae Herba. Approixmately IC50 of two species of Oldelandiae Herba was 380-450 ug/ml. For evaluation of antiangiogenic activity, proliferation assay with HUVECs(Human umblical vein endothelial cells) was done with three samples. Chinese Herba and Korean Herba and root. Korean root and herba was more effective than Chinese Herba. Thus, we found Korean Oldenlandiae was more effective on angigenic activity than Chiness Oldenlandiae. In an anlytical study on effective compounds from Oldenlandiae, the spot of ursolic acid was more marked by Korean Oldenlandiae than by Chinese Oldenlandiae. whereas the spot of asperuloside was more pronounced by Chinese Oldenlandiaethan by Korean Oldenlandiae by TLC analysis.

This study was performed to investigate the antimicrobial activities of the Plagiorhegama dubium extracts against food-borne pathogens. The methanol extract was partitioned into petroleum ether, chloroform, ethyl acetate, and methanol portions. The antimicrobial activity of the P. dubium extracts was determined using a paper disc method against food-borne pathogens and food spoilage bacteria. The methanol extracts of P. dubium showed the highest antimicrobial activity against Staphylococcus aureus and Escherichia coli. The synergistic effect has been found in combined extracts of P. dubium and Hedyotis diffsa as compared to each extracts alone. Finally, the growth inhibition curve was determined using methanol extracts of P. dubium against S. aureus and E. coli. The methanol extract of P. dubium showed strong antimicrobial activity against S. aureus at the concentration of 4,000 ppm. The 4,000 ppm of ethyl acetate portion from P. dubium retarded the growth of S. aureus more than 36 hours and E. coli up to 60 hours. The methanol extracts of P. dubium has been shown the antimicrobial activity against S. aureus and E. coli.
