Seaweeds contain various bioactive compounds. Especially, brown algae (Phaeophyceae), the second abundant group of seaweeds, contain numerous nutraceutical and pharmaceutical substances. In this review, we investigated on the brown algae-related patents and literature. Consequently, the research and development (R&D) trends of patent related to brown algae showed that the large majority was applied as the composition of stem cell culture medium and mostly used as active substances. In conclusion, we suggested that many researchers try to investigate and develop applications of brown algae as the sophisticated-level biomedical materials because brown algae are actively developing as simple-level biomedical materials.

The quantity of heavy metals (As, Cd, Cu, Pb, Zn) contained in marine algae collected in Onsan-myon on the east coast of Korea from March to December 1978 was determined as a part of the environmental base line survey of the Onsan Industrial Base. In general, green algae have a higher Cu content than either brown or red algae, and brown algae have higher As and lower Cu contents, while red algae have a higher Zn content. Significant differences between algal species in either Cd or Pb content were however not found.

This study was to clarify the variations in a marine ecosystem through examining the species composition of benthic algae in the coast of Dokdo Island during summer (June & August, 2003). The total number of species found in benthic algae was 45 composed of 11% green algae, 29% red algae and 60% brown algae. The dominant species were Enteromorpha linza, Cladophora spp. and Codium frgile for green algae, Ecklonia cave, Eisenia bicyclis, Sargassum confusum, S. patens, S. horneri, Myagropsis myagroides for brown algae and Amphiroa cphedrace. A pusilla, Lithophyllum okamurae, Corallina spp. Laurencia pinnata, L. hamata, Chondria crassicaulit, C. dasyphylla, Gelidium amansii, Neosiphonia yendoi and Polysiphonia yendoi for red algae. The number of benthic algal species decreased more in this study than in previous researches. The whitening of the rocky shore might provoke the decrease of benthic algal biomass and species.

The photosynthetic parameters of dark- adapted minimum fluorescence (Fo) and maximum quantum yield of charge separation in PSII (Fv/Fm) were measured in transverse sections of eight species of marine Phaeophyceae (species of Laminariales, Fucales, Desmarestiales, Chordariales) using pulse amplified modulation (PAM) fluorometry. Within each transverse section fluorescence was measured in three regions corresponding to outer cortical and meristoderm cells, inner cortical cells and innermost medullary cells. Minimum fluorescence declined from 19-74% (mean of 39%) from outermost to innermost cells. Maximum quantum yield varied from 0.51-0.59 in outermost cell layers and this was reduced to 0.23-0.40 in innermost cell layers, with an average reduction of 50%. Despite the reduction Fo in medullary cells (inner), medullas of all species showed maximum quantum yields consistent with a photosynthetic role in carbon fixation. These results show that medullary cells of complex brown algae have more than a role in structure, storage or transport, and may also provide an important role in carbon fixation.

최근에 해양자원에 있는 동물, 해조류 곰팡이 세균에서 신규 잠재적인 후보약효제가 조사되어 왔다. 본 연구에서는 치료제를 탐색하기 위하여 암전이, 관절염, 만성염증 및 주름형성에 주요한 역할을 하는 기질금속단백질분해효소(s) (MMPs)를 목적효소로 이용하였다. 5종의 녹조류, 18종의 홍조류, 4종의 갈조류를 포함한 다양한 해조류가 사람피부섬유아세포 및 섬유아육종세포로부터 유래된 기질금속단백질효소에 미치는 영향을 gelatin zymography를 이용하여 조사하였다. 사람피부섬유아세포에서는 홍조류중에서 Laurencia okamurae, Polysiphonia japonica, Grateloupia lanceolate 및 Sinkoraena lancifolia에서 MMP-2 억제효과가 관찰되었다. 반면에 녹조류의 Enteromorpha compressa와 Enteromorpha linza, 갈조류의 Peltaronia bighamiae and Sargassum thunbergii에서는 MMP-2 활성화가 관찰되었다. 사람섬유아육종세포에서는 MMP-9 활성화가 갈조류인 Sargassum thunbergii, 홍조류의 Polysiphonia japonica, 녹조류의 Enteromorpha compressa와 Enteromorpha linza의 존재 하에서는 감소되었다. 본 연구에서 흥미로운 발견은 녹조류의 E. compressa와 E. linza 및 갈조류의 S. thunbergii는 정상세포에서는 MMP-2에 대하여 활성화 효과를 나타내었으나, 암세포에서는 MMP-9응 억제하는 효과를 나타낸 것이다. 이러한 결과는 녹조류의 E. compressa와 E. linza 및 갈조류의 S. thunbergii는 항암 효능을 발휘할 수 있는 성분을 함유하고 있다는 것을 암시하고 있다.

In order to clarify the accumulation of radioactive materials in marine organisms of Korea, the present investigation is carried out with 54 samples of edible seaweeds collected from eight sampling sites along the coast of Korea during September, 1973 and April, 1974. In this paper, ash contents, gross alpha activities and gross beta activities are detected. The ash content is 7.53- 15.95% in the species investigated. Among the algal phyla it is about 13.13% in green algae, 12.77% in brown algae, and 10.77% in red algae on an average. On the other hand, gross alpha activities fluctuate from 180.0 pCi/Kg to 1082.6 pCi /Kg-fresh material experimented, and are 530.72 pCi/Kg on an average. They increase from green to red and brown algae, in turn. The activities in a single species collected at the same season increse from eastern to western and southern coasts of Korea, in turn. Gross beta activities, however, fluctuate from 2.40 nCi/Kg to 22.14 nCi/Kg-fresh material experimented, and 9.03 nCi/Kg on an average. They increase also from green to red nd brown algae, in turn. The gross beta activities are specially higher in Sargassum thunbergii, 22.14 nCi/Kg It is expected that this plant could be an indicator to detect the activities in the marine algae along the coast of Korea.

We examined cell regeneration efficiency of brown marine algae living in Jeju coast for search of a novel therapeutic device with cutaneous wound healing materials. The five algae were collected and compared with epidermal growth factor (EGF) as a positive control in the assays of cell proliferation and cell migration of NIH3T3 fibroblast cells. Among the 80% methanol extracts of these brown algae, the two algal extracts from Ishige foliacea and Colpomenia bullosa showed the proliferative effects of the cells similar to the effect of EGF. Besides it was found that Colpomenia bullosa extract significantly enhanced cell migration of NIH3T3 cell. In the study, therefore, we confirmed that the Colpomenia bullosa extract improved proliferation of NIH3T3 cell and a potential candidate for cultaneous wound healing.

Continued to the previous papers, the present investigation is carried out to clarify cesium-137 activities and potassium contents among 54 samples of edible marine algae collected along the coast of Korea during September, 1973 and April, 1974. The potassium contents are variable, 1.5-29.6%, and 11.36% on an average, while most of the members contain them about 10-16% generally. Among the algal phyla, they are 13.49% in green, 10.82% in brown and 16.46% in red algae, respectively. Cesium-137 activities are variable, 0.19-8.13 pCi$\^$137/ Cs/g K, and 2.35 pCi$\^$137/Cs/g K on an average in the samples investigated. Among the algal phyla they are 4.35 in green, 2.17 in brown and 0.89 pCi $\^$137/Cs/g K in red algae, respectively. Green algae contain especially higher activities compared with the other two groups. The brown alga, Myelophycus caespitosus shows the highest activities, 8.13 pCi$\^$137/Cs/g K, among the members investigated. Considering the concentration factor, this plant would be an indicator plant of cesium-137 among the marine algae along the coast of Korea.
