Object To study the chemical constituents of Bidens bipinnata L Methods Isolation and purification were carried out on silica gel, ODS column, and Sephadex LH 20, HPLC, identified by physicochemical properties and structurally elucidated by spectral analysis Results From n BuOH extract of B bipinnata, 12 compounds were obtained and identified as: 6 O ? D glucopyranosyl 6, 7, 3′, 4′ tetrahydroxyaurone (Ⅰ), 6 O (6″ acetyl ? D glucopyranosyl) 6, 7, 3′, 4′ tetrahydroxyaurone (Ⅱ), quercetin 3 O ? D glucopyranoside (Ⅲ), quercetin 3 O ? L rhamnoside (Ⅳ), iso okanin 7 O ? D glucopyranoside (Ⅴ), esculin (Ⅵ), (E) 2 hexenyl O ? D glucopyranoside (Ⅶ), n hexyl O ? D glucopyranoside (Ⅷ), isopentyl O ? D glucopyranoside (Ⅸ), n butyl O ? D fructofuranoside (Ⅹ), n butyl O ? D fructofuranoside (Ⅺ), n butyl O ? D fructopyranoside ( ⅩⅡ ) Conclusion All of these compounds, except Ⅰ and Ⅴ, are obtained from the plant for the first time

Objective To study the chemical constituents of brown alga Sargassum fusiforme.Methods The compounds were isolated by silica gel chromatography,ODS chromatography,and preparative HPLC,and their structures were elucidated on the basis of chemical and spectroscopic methods,including HR EI-MS,1D and 2D NMR spectral techniques.Results Six sterols and two glycolipids were isolated from the n-hexane soluble part of ethanol extract of S.fusiforme and their structures were identified as fucosterol(Ⅰ),24R,28R-and 24S,28S-epoxy-24-ethylcholesterol(Ⅱ),24-hydroperoxy-24-vinylcholesterol(Ⅲ),29-hydroperoxystigmasta-5,24(28)-dien-3?-ol(Ⅳ),(24S)-5,28-stigmastadien-3?,24-diol(Ⅴ),(24R)-5,28-stigmastadien-3?,24-diol(Ⅵ),1-O-myristoyl-3-O-(6′-sulfo-?D-quinovopyranosyl) glycerol(Ⅶ),and 1-O-palmitoyl3-O-(6′-sulfo-?-D-quinovopyranosyl) glycerol(Ⅷ).Conclusion This is the first report for the isolation of Ⅳ,Ⅶ,and Ⅷ from alga of Sargassum(Turn.) Ag.,and compounds Ⅱ and Ⅲ from this alga.The isomers of saringosterols 24S(Ⅴ) and 24R(Ⅵ) from this alga are obtained by preparative normal-phase HPLC for the first time.

Oral administration of red ginseng extracts (1% in diet for 40 weeks) resulted in the significant suppression of spontaneous liver tumor formation in C3H/He male mice. Average number of tumors per mouse in control group was 1.06, while that in red ginseng extracts-treated group was 0.33 (p<0.05). Incidence of liver tumor development was also lower in red ginseng extracts-treated group, although the difference from control group was not statistically significant. Anti-carcinogenic activity of white ginseng extracts, besides red ginseng extracts, was also investigated. In the present study, the administration of white ginseng extracts was proven to suppress tumor promoter-induced phenomena in vitro and in vivo. It is of interest that oral administration of the extracts of Ren-Shen-Yang- Rong-Tang, a white ginseng-containing Chinese medicinal prescription, resulted in the suppression of skin tumor promotion by 12-o-tetradecanoylphorbol-13-acetate in 7,12-dimethylbenz[a]anthracene-initiated CD-1 mice. These results suggest the usefulness of ginseng in the field of cancer prevention.

The aims of this study are 1. to evaluate the usability of workshop to introduce and manage distress screening effectively and efficiently and to use it for cancer patients and their family and 2. to consider the appropriate subject of workshop. All of the participants answered the questionnaire on the site (n=51). Their knowledge about screening practice, various screening tools and how to use screening tools and data from screening tool were significantly improved after the workshop. The workshop was highly regarded by participants. Thirty-eight of fifty-one patients responded to web questionnaire three months later (Response rate: 75%). More than thirty percent of participants put into practice what they learned in the workshop. The workshop decreased factors to interfere screening practice three months later. Knowledge about how to use screening tools was negatively correlated to number of cancer patients at hospital where participants worked and number of their hospital beds. And factor to interfere screening practice was negatively correlated to how long participants were involved in palliative care team. This study indicated the usability of workshop to spread screening triage program regarding cancer patients’ distress. The workshop may be appropriate for medical staffs who have relatively much experience of palliative care team and who have difficulty in screening practice at designated cancer hospitals where number of cancer patients is relatively large.
