Earth worm (Eisenia andrei) and clam worm (Perinereis linea) have been used as anti-bacterial and anti-inflammatory agent. However, it is unclear how they exerted their physiological effects in macrophages. In this experiment, the anti-inflammatory and antioxidant effects of clam worm extract (CWE) and earth worm extract (EWE) in RAW264.7 cells were examined by measuring MDA, catalase, SOD, GSH-Px and inflammatory cytokines (nitric oxide, iNOS, interleukin-$1{\beta}$ and tumor necrosis factor-${\alpha}$). Treatment with CWE significantly increased the activities of catalase, SOD and GSH-Px in RAW264.7 cells and decreased the level of MDA. Interestingly, treatment with CWE induced more activities of SOD than EWE. In addition, CWE decreased NO production, iNOS, COX-2, TNF-${\alpha}$ and IL-$1{\beta}$ in RAW264.7. The EWE also decreased NO production and iNOS, but increased COX-2 and IL-$1{\beta}$ suggesting that CWE could be better resources for anti-inflammatory and antioxidant agent than EWE. Taken together, these results indicate that CWE has the potential as a natural antioxidant and a therapeutic for inflammation-related diseases.

In this research, food waste source reduction model for apartment was investigated. In spite of prohibition of direct landfill of food waste and continuous efforts made by government and local government, food waste production increases steadily. Recycling ratio of the food waste increases every year, but its products have many problems like low quality, stability, salt, odor etc. Household occupies 63.3% of whole food waste production and this is subject to be a key factor to control food waste. We surveyed S apartment in Kwangju city as a model case, in which administrative office and women's association adopted clean plate eating, separation of raw food waste and earth worm composting as a series of method for source reduction and recycling inside the apartment. With the help of residents' participation and practice, food waste production decreased 15.6% from 0.31 g/capita/day in 2007 to 0.26 g/capita/day in 2009 (domestic average 0.30 g/capita/day). Separation of raw food waste and its composting using earth worm were very effective, and were subject to resolve the problems of present food waste treatment technologies. And earth worm composting was very useful in environmental, economical, societal and educational aspects. Instead of economical incentive, educational programs about food value, environmental problem and critical method for food waste separation were more effective for promotion of source reduction. From the analyses on the process and success factors in this model, we could conclude that leader's role was one of the key factors for the settlement of source reduction, and that was to understand the seriousness of the food waste and to seek solution, to test techniques, and to practice by oneself. Furthermore, networking and collaboration among residents, local government, NGO and local press promoted residents' participation, and it was through various education and investigation. Finally, source reduction and self recycling model of food waste in the apartment, that applies separating raw food waste and earth worm composting based on the collaboration among residents, local government, NGO, and local press, should be disseminated, and environmental policy also should be changed to make it possible.

Isoimperatorin and Oxypeucedanin isolated from root of Angelica Koreana Max. (Umbelliferae) that is used as "Kang-Whal" a botanical drug, in Korea, Show following general pharmacologic activities. The treatment with Oxypeucedanin on the exercised duodenum of the rabbit increased the motility of it while isoimperatorin shows little effects. But on the exercised heart of the frogs, both components depressed its contractility. Whereas Oxypeucedanin depressed both blood pressure of the carotied artery and respiration of the rabbit, Isoimperatorin tends to increase blood pressure, respiration and the tonus of the muscle of the earth worm. Oxypeucedanin did not affect the tonus of the muscles of the earth worm, but depressed the uterus contraction of the rabbit, which was, on the contrary, increased by Isoimperatorin.

The effects of earthworm casts as a plant growth media on the growth of orchardgrass seedlings and the changes of physico-chemical properties in worm casts mixture soils were investigated during the growth period of 1998. Worm casts were mixtured with vermiculite, perlite and peat moss, and mixture ratios of worm casts with commercial recommended soil were 100:0(control), 75:25, 50:50, 25:75, and 0:100, respectively. The results were obtained as follows; 1. Plant length(PL) was increased in higher mixture ratios of worm casts and peat moss than those of other mixture ratios of commercial recommended soils. 2. Number of tillers(NT) were significantly increased in mixture ratios of worm casts and peat moss(50:50) and 100% of vermiculite. 3. Root length(RL) was significantly differences between mixture ratios at the worm casts, and the highest value was obtained at all mixture ratios of worm casts and perlite. 4. Dry weight of leaf(LW) was not significantly differences at mixture ratios of 50:50 in all treatments. Especially, between the mixture ratios of worm casts with peatmoss(25:75) and peat moss(75:25) were not significantly differences in dry weight of leaf(LW). The highest value of dry weight of leaf(LW) was obtained at mixture ratios of peat moss and worm casts. 5. Dry weight of tillers(SW) was not significantly differences at mixture ratios of 50:50 in all treatments, and peat moss(75:25) and vermiculite(75:25), respectively. 6. biological yield(BY) at all treatments were increased by yield components of dry weight of tillers(SW), dry weight of root(RW) and length of root(RL). 7. The biological yield of orchardgrass seedlings was greatly increased with mixture ratios of worm casts and peat moss over the 50%.

This study was conducted to investigate the expandibility of sludge treatment by earthworm through real scale experiment and the optimum counter-plan for organic sludge treatment. For the purposes, sludge removal efficienciesof night-soil using earthworm and it's behavior according to the transplanting methods of the earthworm on non-cover worm bed or in the green house worm bed were compared. Sludge uptake rates on non-cover worm bed for 6 months were $0.27{\sim}0.33ton/m^2$ and the excrement of earthworm yields $0.15ton/m^2$(44.1~46.7% of raw night soil sludge dosage). These results were not much different from the worm bed in the green house. The average and maximum earthworm density were about $6.5kg/m^2$ and $7kg/m^2$ respectively on the non-cover worm bed. The density of the worm bed was comparatively higher in spring and fall terms but lower in summer. The amount of old earthworm was much plenty than young earthworm on the non-cover worm bed, resulting in reverse distribution type of pyramid. From the experiments on non-cover worm bed(7,000 pyeong)and in the green house worm bed(1,200 pyeong), it was concluded that landfill and transporting cost could be reduced when the earthworm was applied for the night-soil sludge treatment. Profits from the excrement sale of earthworm was 9,600,000 won. Through this study, it was founded that earthworm treatment method for organic sludge are much more environmentally sound than landfill treatment.

Insect/worm is a source of protein food, more calcium than you think, made up of low-fat and high protein in the worms, 20% of the entire protein, nutrients, and so. because of this, the value of any insect food will rise. Is not argued that enough, livestock methane from gaseous material of the earth temperature no phi but not small role, and indeed. If a non-carbone missions from livestock are less and consequently the production of biofuels using worms because it is also expected to be available to the worms in cattle, such as no benefit is expected that you will be spotlighted.

Hox genes are a family of regulatory gene encoding transcription factor that primarily play a crucial role during development. Several indications suggest their involvement in the control of cell growth and regenration. RT-PCR and souther blot analysis revealed that labial-like gene was increasingly expressed along a spatial gradient in the anterior region of intact worm. During head and tail regeneration, labial-like gene was expressed only in the head region of regenerating body pieces, suggesting that the gene is involved in the anteroposterior patterning in earth-worm. This result could give us information on the significance of Hox genes and the relationship between Hox genes during regeneration.

It is really hard for the material factors to basically improve quality of life, since it is the only partial means of the survival and activity of life. Development of Eigen Shin-Tou-Jil(Proper Body·Earth materials), therefore, must be concentrated on providing man with essential meaning of life, not with simply economic advantage. Eigen Shin-Tou-Jil(Proper Body·Earth materials) which is formed through long passage of time in the original environments that include the climate and nature features of a special region, the representative examples are like Korea Bong-sam(a kind of genseng) of Yellow Earth etc. Unfolding the Eigen Shin-Tou-Jil(Proper Body·Earth materials) by the Algorithm of Human-ware means the development for manifesting individual eigen motives and traits as subject of behavior(Gene-ware). It is because all plants, animals, inanimate objects, including Human, have evolved with their own values in the ecosystem. It was reported that a Baeksong(white pine tree), grown well up in TongEeDong, Seoul, Korea had rarely grown up during the period suppressed by Japan. By the developments of Bio-Engineering, we also found that 40% of gene base sequence of C. Elegance(a kind of worm) is identical to that of characteristic Human. In this reason, through considering common characteristics between Human and Nature, the developments of Eigen Shin-Tou-Jil(Proper Body·Earth materials) must begin with epoch for manifesting and understanding individual's Eigen motives and traits as subject of behavior(Gene-ware)

Moderately diverse, but very abundant trace fossils are found from the Late Pleistocene deposits of Jeju Island, Korea. Vertical I-, Y- and U-shaped domichnia of annelids or decapods are, over 2500, extremely abundant, 3D network domichnia of callianassids are, over 200, very abundant, and small sinuous trails of nematode repichnia are, over 50, abundant in number. Horizontal trails attributable to polychaete or worm-like animals are, less than 50, common, but horizontal spreiten burrows, fish traces and crab trackways are, less than 10, rare in occurrence. Of these trace fossils, Taenidium barretti, Undichna britannica and Undichna unisulca represent the first record from the Pleistocene in Asia. Psilonichnus upsilon is the second record in Asia. Crab trackways probably produced by underwater punting gait of sideway walking crabs may represent the first record in the world. In addition, diverse and very abundant footprints of more than 500 hominids, more than 200 birds and more than 1000 mammals are closely associated with these invertebrate trace fossils. Trace fossil assemblage integrated with sedimentary facies is interpreted to have been formed in the marginal marine foreshore to backshore environment corresponding to the Psilonichnus and Skolithos ichnofacies.
