Pancreatic lipase is a potential therapeutic target for the treatment of diet-induced obesity in humans. In an ongoing search for new pancreatic lipase inhibitors from natural sources, a methanolic extract of marine brown algae, Eisenia bicyclis, showed a significant inhibitory effect against pancreatic lipase. Bioassay-guided isolation of this methanolic(More)
A bacterial strain named AB-4 showing algicidal activity against Chattonella marina was isolated from coastal water of ULjin, Republic of Korea. The isolated strain was identified as Bacillus sp. by culture morphology, biochemical reactions, and homology research based on 16S rDNA. The bacterial culture led to the lysis of algal cells, suggesting that the(More)
OBJECTIVES The purpose of this study was to investigate the impact of practicing qigong on middle-age subjects with essential hypertension. Impacts on blood pressure, reported self-efficacy, perceived benefit, and emotion were observed. DESIGN Thirty-six (36) adult volunteers were assigned to either a waiting list control or a qigong group that practiced(More)
This study was designed to investigate the efficacy of Qigong as a non-pharmacological treatment of hypertension and evaluate the contribution of Qigong in the blood pressure (BP) reduction of essential hypertension patients. Fifty-eight patients volunteered to participate in this study and were randomly divided into either a Qigong group (n = 29), or a(More)
A multivalent approach to discover a novel antibiotic substance against methicillin-resistant Staphylococcus aureus (MRSA), a marine bacterium, UJ-6, exhibiting an antibacterial activity against MRSA was isolated from seawater. The isolated strain was identified to be Pseudomonas sp. by the morphology, biochemical, and genetical analyses. The ethyl acetate(More)
BACKGROUND In an effort to develop alternative therapeutic agents, strong inhibitory activity against α-glucosidase and α-amylase was detected in Eisenia bicyclis methanolic extract. RESULTS In this study, two phlorotannins were isolated from E. bicyclis and characterised by chromatography and nuclear magnetic resonance. The active substances were(More)

This study was designed to survey college students about their knowledge and use of Uwhangchungsimwon (UC), a Traditional Oriental herbal remedy for emergency and acute treatment of stroke, numbness, hypertension, epilepsy and arteriosclerosis. Students at three female nursing colleges in Korea completed a questionnaire containing 29 questions about the(More)
Sea tangle has long been used as Korean folk remedy to promote material health, and is one of the popular dietary supplement. This study was designed to evaluate the protective effect of fermented sea tangle (FST) against ethanol and carbon tetrachloride (CCl(4))-induced hepatotoxicity in rats. Sprague-Dawley rats were orally treated with FST (25, 250, 2500(More)
This work describes the anti-MRSA activity of aminoderivatized chitosans. Two kinds of aminoethyl-chitosans (AEC), AEC90 and AEC50, having degrees of deacetylation of 90% and 50%, respectively, exhibited the strongest anti-MRSA activities by presenting MICs of 16-64 microg/mL against two standard strains and twelve clinical isolates. The bactericidal(More)
