In an attempt to find bioactive natural products with an anti-inflammatory activity, we evaluated the effects of the methanol extract of Fomes fomentarius (MEFF) on in vivo anti-inflammatory and anti-nociceptive activities. MEFF (50, 100 mg/kg/d, p.o.) reduced acute paw edema induced by carrageenin in rats, and showed MEFF analgesic activity, as determined(More)
This paper provides an overview of the Korean Burden of Disease (KBoD) study, which was the first such study to assess the national burden of disease using disability-adjusted life years (DALYs) in an advanced Asian country. The KBoD study generally followed the approach utilized in the original Global Burden of Disease study (GBD), with the exception of(More)
We have investigated the anti-inflammatory effects of madecassic acid and madecassoside isolated from Centella asiatica (Umbelliferae) on lipopolysaccharide (LPS)-stimulated RAW 264.7 murine macrophage cells. Both madecassic acid and madecassoside inhibited the production of nitric oxide (NO), prostaglandin E(2) (PGE(2)), tumor necrosis factor-alpha(More)
A 35-year-old woman with a history of myomectomy underwent in vitro fertilization and became pregnant. Transvaginal ultrasound revealed a gestational sac within the subserosal area of the posterior uterine wall. The patient was treated successfully with conservative surgery, and the pathologic evaluation of the excised mass demonstrated chorionic villi(More)
ETHNOPHARMACOLOGICAL RELEVANCE Patrinia scabiosaefolia Fisch is used in folk medicines to treat intestinal abscesses, acute appendicitis, and dysentery in Asia. Although recent reports indicate that Patrinia scabiosaefolia has sedative and anti-tumor effects, its effects on ulcerative colitis have not been previously explored. AIM OF THE STUDY To(More)
We previously demonstrated that beta-D-xylopyranosyl-(1-->3)-beta-D-glucuronopyranosyl echinocystic acid (codonoposide 1c), a biologically active compound isolated from the roots of Codonopsis lanceolata, is cytotoxic to cancer cells. In the present study, we investigated the effects of codonoposide 1c on the induction of apoptosis, and its putative action(More)
An integrated study based on hydrogeochemical, microbiological and dual isotopic approaches for nitrate and sulfate was conducted to elucidate sources and biogeochemical reactions governing groundwater contaminants in different seasons and under different land use in a basin of Korea. The land use in the study area is comprised of forests (58.0%), vegetable(More)
To investigate the anti-inflammatory potential of sinapic acid as well as the underlying mechanism involved, we studied the inhibitory effect of sinapic acid on the production of pro-inflammatory mediators in vitro and then evaluated its in vivo anti-inflammatory effect. Sinapic acid inhibited lipopolysaccharide (LPS)-induced nitric oxide (NO),(More)
Hesperetin (3',5,7-trihydroxy-4-methoxyflavanone) is a metabolite of hesperidin (hesperetin-7-O-rutinoside), which belongs to the flavanone subgroup and is found mainly in citrus fruits. Hesperetin has been reported to be an effective osteoinductive compound in various in vivo and in vitro models. However, how hesperetin effects osteogenic differentiation(More)
A DNA fragment encoding the cholera toxin A2 subunit (CTA2) linked to the enterotoxigenic Escherichia coli (ETEC) colony forming fimbrial antigen CFA/I was inserted into a plant expression vector containing the cholera toxin B subunit (CTB) fused to the rotavirus enterotoxin 22 amino acid epitope NSP422. Anti-CFA/I antibodies recognized a single band of(More)
