BACKGROUND Propolis has been used as a folk medicine and has several proven biological activities. Herbal remedies recommended for cancer therapies in Korea. METHODS Matrix metalloproteinase (MMP)-9-inhibitory activity of propolis has been assessed. CAPE as an acting compound was isolated and molecular structure was determined. Anti-invasion activity of(More)
The critical initiating event in atherogenesis involves the invasion of monocytes through the endothelial walls of arteries and the transformation of monocytes from macrophages into foam cells. Human THP-1 monocytic cells can be induced to differentiate into macrophages by phorbol myristate acetate (PMA) and can then be converted into foam cells by exposure(More)
In the present study, we investigated the protective effect of Lycium chinense Miller (Solanaceae) fruit (LFE) against CCl(4)-induced hepatotoxicity and the mechanism underlying these protective effects in rats. The pretreatment of LFE has shown to possess a significant protective effect by lowering the serum aspartate and alanine aminotransferase (AST and(More)
A Korean traditional herbal formulation, Sihoga-Yonggol-Moryo-Tang (SGYMT), is being used for the treatment of many diseases such as tumor, neuropsychiatric, and vascular disorders. The extracts prepared from SGYMT and its herbal ingredients were assayed for the inhibitory effects on tumor-specific matrix metalloproteinases-2 and -9 (MMP-2/9) activities(More)
A water extract of Panax notoginseng Buck F.H. Chen. (Arialiaceae) root (PN) is being used as a therapeutic agent to stop haemorrhages and as a tonic to promote health in Korean and Chinese medicine. The pharmacokinetic profiles of PN have not been accurately investigated. The preliminary aim was to elucidate the pharmacokinetic features of PN. First, the(More)
The effect of water extract of deer antler (DAA) prepared from the pilose antler of Cervus korean TEMMINCK var. mantchuricus Swinhoe (Nokyong) on collagen-induced mouse rheumatoid arthritis (RA) model was studied. Identification of common DAA capable of affording protection or modulating the onset and severity of arthritis may have important human health(More)
Endogenous expression of human membrane type ganglioside sialidase (Neu3) was examined in various cell lines including NB-1, U87MG, SK-MEL-2, SK-N-MC, HepG2, Hep3B, Jurkat, HL-60, K562, ECV304, Hela and MCF-7. Expression was detected in the neuroblastoma cell lines NB-1 and SK-N-MC, and also in erythroleukemia K562 cells, but not in any other cells. We(More)
A phenolic compound responsible for anti-MMP-9, which is known to be involved in tumor cell invasion and metastasis, has been isolated from methanol extracts prepared from stem barks of Euonymus alatus by assay-guided fractionation. The compound has been identified as 5-caffeoylquinic acid (chlorogenic acid; CHA) by NMR and FAB-MS. CHA showed a strong(More)
Interleukin-1beta (IL-1beta) regulates several activities of the osteoblast cells derived from mouse calvarial bone explants in vitro. IL-1beta stimulated cellular proliferation and the synthesis of prostaglandin E2 in the cultured cells in a dose-dependent manner. Furthermore, plasminogen activator activity of the mouse osteoblast was positively affected(More)
