Developing new substance for immunosuppressor or immunomodulator from natural products is extremely important in the present biomedicine. In this paper, we focused our efforts on the mitogenicity and immunochemical properties of the two lectins (LCC-I, LCC-II) obtained from marine animal Lunella coronata coreensis. Immunochemical techniques were employed to elucidate the structural and/or functional similarities between the LCC lectins. Molecular weight of the LCC lectins, LCC-I and LCC-II were estimated to be around 60 KD and 66-70 KD, respectively. LCC lectins were mitogens for murine splenic lymphocytes, and the optimum mitogenic doses were 31.25 $\mu\textrm{g}$/ml and 3.91 $\mu\textrm{g}$/ml, respectively. LCC-II lectin was a good mitogen toward human peripheral lymphocytes at a concentration about 31.25 $\mu\textrm{g}$/ml.

The whole body extract of Lunella coronata coreensis agglutinated nonspecifically human and other animal erythrocytes. A new lectin was purified by the following procedures: 0.15 M NaCl extraction, salt fractionation, gel filtration, anionic and cationic ion exchange column chromatographies. Through these purification procedures, specific activity of LCC-I was increased from 276 to 9714.3 units/mg, And on polyacrylamide gel electrophoresis, LCC-I exhibited one major band. A molecular weight of LCC-I was assumed to be 20,000 by sodium dodesyl sulfate polyacrylamide gel electrophoresis. The purified lectin was relatively stable at various pH and heat. Among the tested sugars, lactose and lactulose inhibited lectin activity at a concentration of 6.25 mM, respectively.

The study had been carried out three times, from April 1987 for the purpose of analysis on the community structure and the distribution patterns of the Molluscan shells at the intertidal zone of Cheju Island. 1) The Molluscan shells collected and identified at all studied sites were composed of 3 classes, 10 orders, 23 families and 42 species.2) In all studied sites, individual numbers according to species were Nodilittorina exigua, Monodonta neritoides, Lunella coronata coreensis, Heminerita japonica in order. On the other hand, the dominant species of the rocky sits were N. exigua, M. neritoides and the rocky and silty-sand sites was Batillaris multiformis.3) In the vertical zonation, in the supralitorial zone, N. exigua was dominant species and the wpper-tidal zone, N. exigua, H. japonica and B. Multiformis were dominant species, but B. multiformis was dominant in the rocky and silty sand sites. In the middle tidal zone, M. neritodes, H. japonica, L. coronata coreensis were dominant and in the lower tidal zond, M. neritodes, L. coronata coreensis, Liolophura japonica were dominant.4)In the analysis on community of Molluscan shells, Chagwi, Pyoson an dAewol sites were more diverse than other sites in the species diversity and environmental inhibits were also favorable.5) Community similarities among the studied sites based on the similarities values were divided into two groups according to the difference of the ground: Hagwi, Chongdal and Sehwa sites group and the others sites group.

A study on the distribution and community structure of benthic molluscan shells of the northern coastal area in Cheju Island was carried out from July 1989 to June 1990. The benthic molluscan shells collected and identified were composed of 3 classes, 9 orders, 29 familes and 81 species. The first dominant species of the wpper intertidal zone of the northern coastal area in Cheju Island was Nodilittorina exigua and second dominant species were Heminerita japonica, Monodenta neritoides, Monodota neritoides, Littorina brevicula, those of middle intertidal zone were Lunella coronata coreensis, Monodonta neritoides and Omphalius rusticus. H. japonica, M. neritoides, O. rusticus, L. coronata coreensis and Niotha livescens were dominant in the lower intertidal zone, and Astralium haematragum was dominant in the infralittoral zone of within 60 feet sea water depth. The benthic molluscan standing biomass of intertidal and infralittoral zones were 145.71-705.55 gr/ /m sup 2 / and 84.57-1645.67 gr/m sup 2/ respectively, But thao among area and zones were apparently differences.

A study on the distribution and community structure of benthic macroinvertebrates on the intertidal zone of Cheju Island was carried out from June 1988 to May 1989. The macroinvertebrates collected and identified were composed of 7 phyla, 14 classes, 29 orders, 71 families and 135 species in this study. The dominant species of the upper tidal zone were Nodilittorina granularis and Heminerita japonica, those of the middle tidal zone were Monodonta neritoides and Lunella coronata coreensis, However, Monodonta neritoides and Chlorostoma arhyrostoma lischkei were dominant in the lower tidal zone. Community dominant indices were significantly high in the upper tidal zone. Macuoinvertebrates species which have the ability of resistance to the physical factors such as, strong waves and exposure to the hot sunlight were mainly distributed on the intertidal zone of Cheju Island. The difference in the number of species among seasons was not significant, but thao among zones was quite apparent and the lower the zone, the more abundant.

Seogundo is a small island adjacent to the southern coast of Jeju Island and connected to it by a boulder beach at low tide Surveys of this area were conducted from 2001 to 2009 to enumerate the mollusks there and also to examine their diversity, relative abundance, and ecological relationships. Both the boulder beach itself and several large tide pools were studied, including the coarse sand substrate and several species of seaweed and coralline algae found in the tide pools. Of the 121 species obtained or observed, there were 97 gastropods, 16 bivalves, and 8 polyplacophorans. Live specimens were obtained for about half of those species. About one third were found on rocky substrate, with the most common species being Nodilittorina radiata and Nerita japonica in the upper intertidal zone, N. radiata and Littorina brevicula in the middle intertidal, and Turbo (Lunella) coronata coreensis and Acanthopleura japonica in the lower intertidal and shallow subtidal. The seaweeds and coralline algae contained about 40% of all mollusk species. The most common mollusks in two species of brown seaweed were Ittibittum parcum, Musculus nanus, and Euplica scripta. In a species of red seaweed, Komaitrochus pulcher was the most frequent, as in the coralline algae, along with M. nanus. The coarse sand in the tidepools contained about 25% of the species, with the Cerithiidae having the largest number. A sample of beach drift contained 17 species, with Bittium aleutaceum and Rissoina (Phosinella) pura being most common. Most species, about 60%, were found in a variety of habitats, especially the marine flora; few species exhibited any habitat preferences. Biographically, Jeju Island is part of the Warm Temperate Northwest Pacific Province and the East China Sea ecoregion with a strong faunal affinity with southern Japan, eastern China, and northeastern Taiwan. Zonal-geographical groupings reveal that the fauna is mainly subtropical-low boreal, preferring moderately warm water, with a somewhat smaller number of tropical-subtropical species.
