Fruits of bog blueberry (Vaccinium uliginosum L.) are rich in anthocyanins that contribute pigmentation. Anthocyanins have received much attention as agents with potentials preventing chronic diseases. This study investigated the capacity of anthocyanin-rich extract from bog blueberry (ATH-BBe) to inhibit photoaging in UV-B-irradiated human dermal(More)
PURPOSE Diabetic glomerulosclerosis is the hardening of the renal glomeruli that can lead to kidney failure. In the early stage of glomerulosclerosis occur renal mesangial expansion and renal filtration dysfunction. Purple corn has been classified as a functional food and is rich in anthocyanins exerting potential disease-preventive activities. The in vitro(More)
We have isolated five furanocoumarins, byakangelicin, phellopterin, imperatorin, isoimperatorin, and oxypeucedanin methanolate, from the roots of Angelica dahurica (Umbelliferae) and prepared five semi-synthesized compounds by the partial reduction of each isolated furanocoumarin, and the effects of these compounds on lipopolysaccharide (LPS)-induced(More)
The present study was carried out to clarify whether tectorigenin and tectoridin isolated from the rhizomes of Belamcanda chinensis (Iridaceae) inhibit angiogenesis by the experimental methods in vitro and in vivo. Tectorigenin and tectoridin decreased angiogenesis of both chick embryos in the chorioallantoic membrane assay and basic fibroblast growth(More)
Numerous polyphenolic compounds have been found to inhibit adhesion and migration of leukocytes to sites of inflammation that are partly regulated by the expression of cell adhesion molecules (CAM) such as vascular cell adhesion molecule-1 (VCAM-1), E-selectin, and platelet endothelial cell adhesion molecule-1 (PECAM-1). Licorice root extracts have been(More)
Ginseng (Panax ginseng C. A. Meyer) has been well known to have a variety of ginsenosides that show diverse biological activities. Especially, the components of ginsenosides are quite different depending on the processing method. Recently, there have been several reports showing that less polar ginsenosides from Korean red ginseng (steam-treated Panax(More)
In cultures of the murine macrophage cell line RAW 264.7, effects of four 2'-hydroxychalcone derivatives, 2'-hydroxy-4'-methoxychalcone (compound 1), 2',4-dihydroxy-4'-methoxychalcone (compound 2), 2',4-dihydroxy-6'-methoxychalcone (compound 3) and 2'-hydroxy-4,4'-dimethoxychalcone (compound 4), on lipopolysaccharide (LPS)-induced production of nitric oxide(More)
The dried unripe fruit of Rubus coreanus, which is well-known in Korea and referred to as 'Bok-bun-ja', has been employed as a traditional medicine for centuries. This crude drug is utilized in Korea for the management of impotence, spermatorrhea, enuresis, asthma and allergic diseases. The principal objective of the present study was to conduct a(More)
The anti-tumor and immuno-stimulating activities of the fruiting bodies of Paecilomyces japonica (PJ), grown on silk-worm larvae and of Cordyceps sinensis (CS), a wild form of Cordyceps Fungi, were investigated. Ethanol extracts of both fungi, when administered for 9 consecutive days, at 50 and 100 mg/kg i.p., caused a significant increase in life span and(More)
The fruit of Terminalia chebula Retz has been used as a traditional medicine in Asia and contains tannic acid, chebulagic acid, chebulinic acid and corilagin. Extract from T. chebula seeds (TCE) has various biological functions. We observed the neuroprotective effects of TCE against ischemic damage in the hippocampal C1 region (CA1) of the gerbil that had(More)
