Polymorphism in the brown alga Dictyota dichotoma (Dictyotales, Phaeophyceae) from Korea
The results suggest that the two types of D. dichotoma from Korea should be classified as a single species and that they may be in the process of speciation due to geographical isolation (allopatric speciation). Expand
Inhibitory effect of Jeju endemic seaweeds on the production of pro-inflammatory mediators in mouse macrophage cell line RAW 264.7
The anti-inflammatory effects and low cell toxicity of these seaweed extracts suggest potential therapeutic applications in the regulation of the inflammatory response. Expand
Antioxidative and antimicrobial activities of Sargassum muticum extracts
The solvent extracts of Sargassum muticum, which were extracted by using several solvents with different polarities, were prepared for use as natural preservatives. The S. muticum extract with 80%Expand
Phylogenetic relationship among several genera of Dictyotaceae (Dictyotales, Phaeophyceae) based on 18S rRNA and partial rbcL gene sequences
The data suggest that the status of the meristem cells should not be a criterion for separating tribes within the family Dictyotaceae and that other hierarchical systems should be adopted to properly reflect phylogenetic relationships. Expand
Molecular phylogeny of Laminariales (Phaeophyceae) inferred from small subunit ribosomal DNA sequences
Considering the molecular data and the reported morphology, life history and sex pheromones of the family, it appears likely that the Pseudochordaceae might have branched off first from the laminarialean lineage that leads, through the Chordaceae, to the advanced Laminariales (i.e. the Alariaceae, Laminariaceae and Lessoniaceae).

Jeju seaweeds suppress lipopolysaccharide-stimulated proinflammatory response in RAW 264.7 murine macrophages.
The findings suggest that Jeju seaweed extracts have potential therapeutic applications for inflammatory responses, and are suggested to be a potential therapeutic application for TNF-α patients. Expand
Temporal Variations of Seaweed Biomass in Korean Coasts: Munseom, Jeju Island
【Seaweed biomass was estimated using a nondestructive method in the rocky subtidal zones in Munseom, Jeju Island, Korea from July 2006 to April 2008. Seasonal samplings were done at the depth of 1,Expand
Taxonomic reappraisal of Dilophus okamurae (Dictyotales, Phaeophyta) from the western Pacific Ocean
Molecular phylogenetic analyses, based on three separate loci, large subunit rDNA (LSU), rbcL and psbA confirm the close phylogenetic relationship between D. okamurae and R. radicans, and the recently described genus Rugulopteryx. Expand
Anti-inflammatory effects of apo-9′-fucoxanthinone from the brown alga, Sargassum muticum
This is the first report describing effective anti-inflammatory activity for apo-9’-fucoxanthinone′-fu Coxanthnone isolated from S. muticum, and may be a good candidate for delaying the progression of human inflammatory diseases and warrants further studies. Expand
Ulva and Enteromorpha (Ulvaceae, Chlorophyta) from two sides of the Yellow Sea: analysis of nuclear rDNA ITS and plastid rbcL sequence data
Ribotype network analysis revealed that the common ribotype, occurring in China, Korea and Europe, is connected with ribotypes from Europe and China/Japan, and intraspecific genetic polymorphism of each species was low among samples collected worldwide. Expand
