To utilize canned oyster processing waste water effectively, this study was carried out to prepare instant powdered soup using the waste water (IPSW), Instant powdered souu from oyster hot-water extracts (IPSE) was prepared by mixing hot-water extracts powder (15 g) with table salt (5 g), cream powder (19 g), milk replacer (12 g), wheat flour (20 g), corn flour (15 g), starch (5 g), glucose (7.5 g) and onion powder (1.5 g). In preparing IPSW, mixed powder from wash water and boiling liquid waste, instead of powder from hot-water extracts and table salt, was added (powder from boiling liquid waste: powder from wash water= 12: 8) and other additives were added in proportion to those in the IPSE, The IPSW consists mainly of carbohydrates (about $72\%$). It was not different from the IPSE. The volatile basic nitrogen, viable cell counts, coliform group of the IPSW contains 33.4 mg/100g, $2.2\times10^4CFU/g$, <180 MPN/100g, respectively, and its water activity has 0.257. So it was a hygienically safe and conservable instant food. The main fatty acids of IPSW were 16: 0 and 18: 1n-9. Its chemical score of protein was $61.4\%$ and its main inorganic matter was iron. According to a sensual evaluation, in contrast to the IPSE, the IPSW had a bit lower aroma but better taste, It was concluded from the above chemical and sensory evaluation that even the boiling liquid waste which had been mostly abandoned because of its high table salt content can be used as a good material for instant powdered soup if it's powdered and mixed adequately with powder from wash water, and its table salt content is properly adjusted.
Purpose: Sargassum horneri (S. horneri) is a species of brown macroalgae that is common along the coast of Japan and Korea. The present study investigated the immuno-modulatory effects of different types of S. horneri extracts in RAW264.7 macrophages. Methods: S. horneri was extracted by three different methods, hot water extraction, 50% ethanol extraction, and supercritical fluid extraction. Cell viability was then measured by MTT assay, while the production levels of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-6 (IL-6), and nitric oxide (NO) were measured by enzyme-linked immunosorbent assay and Griess assay, respectively. The expression and activation levels of inducible NO synthase (iNOS), mitogen-activated protein kinase (MAPK) and nuclear factor ${\kappa}B$ ($NF-{\kappa}B$) were examined by western blot analysis. Results: The three different S. horneri extracts were nontoxic against RAW 264.7 cells up to $50{\mu}g/mL$, among which treatment with hot water extract (HWE) of S. horneri significantly enhanced the production of TNF-${\alpha}$, IL-6, and NO in a dose-dependent manner. Hot water extract of S. horneri also increased the expression level of iNOS, suggesting that up-regulation of iNOS expression by HWE of S. horneri was responsible for the induction of NO production. In addition, treatment of RAW 264.7 macrophages with HWE of S. horneri increased the phosphorylation levels of ERK, p38 and JNK. Furthermore, the activation and subsequent nuclear translocation of $NF-{\kappa}B$ was enhanced upon treatment with HWE of S. horneri, indicating that HWE of S. horneri activates macrophages to secrete TNF-${\alpha}$, IL-6 and NO and induces iNOS expression via activation of the $NF-{\kappa}B$ and MAPKs signaling pathways. Conclusion: Taken together, these findings suggest that HWE of S. horneri possesses potential as a functional food with immunomodulatory activity.

This study was conducted to determine the effects of a pre-planting fertilizers with various $NH_4{^+}:NO_3{^-}$ ratios in a coir dust:peatmoss:perlite (3.5:3.5:3.0, v/v/v) medium on the growth of hot pepper (Capsicum annuum L. cv. Nokkwang) plug seedling. Nitrogen levels were fixed to $300mg{\cdot}L^{-1}$ and the $NH_4{^+}:NO_3{^-}$ ratios were varied to 0:100, 27:73, 50:50, 73:27, and 100:0. The 50-cell trays were filled with treatment media containing pre-plant fertilizers, then seeds were sown. After seeds were germinated, the trays were moved to greenhouse and seedlings were feed with 13-2-13 and 20-9-20 fertilizers, alternatively. The changes in pH and EC were measured every week and soil solution for nutrient concentrations were analyzed in week 0, 3, and 7. The measurements of seedling growths as well as analysis of tissue nutrient contents were also conducted in week 7. The varied $NH_4{^+}:NO_3{^-}$ ratios did not influence on the pHs of root media after incorporation of pre-planting fertilizers, but the ECs were heightened as proportion of $NH_4{^+}$ to $NO_3{^-}$ were elevated. During the raising of seedlings, the pHs rose over time in the treatments of 0:100 and 27:73 ($NH_4{^+}:NO_3{^-}$). The concentrations of all macro-elements in root media decreased gradually as seedlings grew in all treatments. The seedling growths 7 weeks after seed sowing were the highest in the treatments of 27:73 and 50:50 ($NH_4{^+}:NO_3{^-}$) and those became worse in the treatments of higher $NH_4{^+}$ ratios than 73%. In terms of inorganic element contents based on the dry weight of above ground tissue, the treatment of 0:100 showed the lowest content of Ca, Mg, Na, Cu, Mn, and Zn. Based on the results, it is desired that $NH_4{^+}$ ratio in pre-planting fertilization is maintained to be 50% or less for the raising of hot pepper plug seedlings.

Antioxidative, antimicrobial activities and Raw 264.7 cell viability as cytotoxicity of various solvent extracts from leaf of Eriobotrya japonica Lindl. dried by different methods were investigated for processing as functional ingredient. In DPPH radical scavenging activity, RLE (80% EtOH extract of raw leaf) and FLE (80% EtOH extract of freeze-dried leaf) exhibited strong scavenging effect on $300{\mu}M$ DPPH radical solution (1.71 mg/mL and 2.11 mg/mL for RLE $SC_{50}$ and FLE $SC_{50}$). Also in nitric oxide scavenging activity, RLE and FLE showed strong activities (83.9% and 82.2% in 5 mg/mL sample concentration). Total phenolic compound contents of each extracts were found to be $73.7{\sim}215.4$ mg/g and RLE was showed the highest phenolic compound content. Also, total flavonoid contents were found to be $24.85{\sim}110.3$ mg/g and RLE was showed the highest flavonoid content. In antimicrobial activity, RLE was showed higher growth inhibition effect against all microbial strains. RLE, RLW (hot water extract of raw leaf), and FLW (hot water extract of freeze-dried leaf) exhibited strong antimicrobial activities against MRSA and S. aureus. In measurement of cytotoxicity by MTT assay, Raw 264.7 cell viabilities of 80% EtOH extracts showed better effect than water extracts. Especially viability of RLE was found be over 100% in every tested sample concentration.
As a result of measuring the polyphenol content of Humulus japonicus (HJ) extract according to the collection time and extraction solvent, bothhot water extract and 70% ethanol extract were collected and extracted in June, and the polyphenol content was high. When the harvesting time was the same, the polyphenol content of the ethanol extract was higher than that of the hot water extract. As a result of measuring the antioxidant activity of HJ extract by measuring electron-donating ability, SOD-like activity, and ABTS radical scavenging ability, HJ6E, which has the highest polyphenol content, showed the highest activity. In addition, in the case of the extract collected in August, the polyphenol content was similar. However, the antioxidant activity of the ethanol extract was high, sothe antioxidant activity remained high when extracted with 70% ethanol. As a result of measuring tyrosinase inhibitory activity for evaluating skin whitening activity, HJ6W did not show any activity. The activity at the highest concentration was 16.18% for HJ8W, 8.07% for HJ6E, and 14.7% for HJ8E. Therefore, the content of ingredients showing skin whitening activity was higher in August than in June. In the elastase inhibitory activity for evaluating the anti-wrinkle activityof the skin, the ethanol extract showed very little activity, and the hot water extract did not. In addition, since all extracts do not show astringent activity, it is judged that it is not appropriate to use HJ as a functional ingredient for preventing wrinkle formation. As a result of measuring the cell viability of HJ6E, which showed the highest polyphenol content and antioxidant activity, it showed a cell proliferation effect at low concentrationsbut strong cytotoxicity at concentrations above 50 ㎍/mL. In the case of the NO production inhibitory ability, as the concentration increased, the NO production of Raw 264.7 was suppressed. Theamount of NO production at 1,000 ㎍/mL decreased to 40.7%. However, whether these results are due to cytotoxicity or the extract's efficacy is a part that requires further research.

This study investigated the possibility of application of the recently introduced cylindrical paper pot seedlings in hot pepper (Capsicum annuum L.) cultivation. The seedling growth, initial rooting after planting and accumulated fruit yield were investigated with the treatments of tray type (paper pot and plug) as a main factor, tray cell number (40 cell and 50 cell) as a sub-factor, and fertigation method (continuous fertigation and fertigation after 35 days sowing) as a sub-sub factor, respectively. The growth of pepper seedlings was significantly affected by tray type and fertigation method showing the highest value at 50 cell plug tray with continuous fertigation, and the effect of fertigation was greater than that of trays. 'Cheongyang', 'Daekwonseoneon' and 'Longgreenmat' cultivar showed all the same pattern in seedling growth. These three-cultivar seedlings were planted in plastic house and in open field in Jeonju area, respectively, and another 'Daekwonseoneon' seedlings raised Yeongyang local area was also planted at the same area. There was no difference in the rooting of 'Cheongyang' pepper at 2 weeks after planting in plastic house. The accumulated fruit weight was not significantly different between paper pot seedlings and plug seedlings in three cultivar grown in plastic house. However, that of 'Cheongyang' pepper showed higher at paper pot seedlings than plug seedlings and the other two cultivar were higher at plug seedlings in open field. 'Daekwonseoneon' pepper yield grown in open field in 'Yeongyang' area was not significant between paper pot seedlings and plug seedlings. In conclusion, the pattern of seedlings growth grown in the cylindrical paper pot was the same as those of the conventional plug seedlings and also fruit yield was similar between paper pot seedlings and plug seedlings even though minute difference among cultivars. These results suggest that pepper seedlings grown in paper pot should be highly applicable to pepper cultivation.

Curcuma longa L. (CL) is a well known traditional medicinal plant that is also used in curries and mustards as a coloring and flavoring agent. However, CL is not usually used as a food source due to its bitter taste. We investigated the immunomodulatory effect of CL fermented by Aspergillus oryzae (FCL) on RAW 264.7 cells. FCL was extracted with cold water (CW), hot water (HW), 20% ethanol (20% EtOH) and 80% ethanol (80% EtOH), after which its effects on phagocytic activity, tumor necrosis factor-alpha (TNF-${\alpha}$), nitric oxide (NO) production, natural killer (NK) cell activity and mRNA expression of LP-BM5 eco were investigated. Phagocytic activity was increased in HW and 20% EtOH when compared to the control. The secretion of nitric oxide (NO) from RAW 264.7 cells did not change significantly relative to the control. However, TNF-${\alpha}$ was significantly increased by the addition of FCL extracts. Moreover, FCL 20% ethanol extract showed a four fold increase in NK cell cytotoxity relative to the control group. Finally, we observed suppressed mRNA expression of LP-BM5 eco in FCL extracts, especially in the 20% ethanol extracts group. These results indicate that the FCL extracts can be used as a functional material due to their effective immunomodulating activities.
In this study, the effect of the Opuntiahumifusa extracts on proliferation, alkaline phosphatase (ALP) activity, collagen synthesis and ROS level of a cell was investigated using an osteoblast. Opuntiahumifusawas separated intoOpuntiahumifusapeel (OH-P), seed (OH-Se) and stem (OH-St).These were subjected to extraction by using hot water and ethanol. The proliferation of the MC3T3-E1 osteoblastic cells that were treated with OH-Se water extract were increased by approximately 120%. Regarding the effects of OH-Se on ALP activity, the $50{\mu}g/ml$ ethanol extract group showed the highest activity. The synthesis of collagen increased significantly in response to treatment with OH-Se water extract. The ROS scavenging effects of Opuntiahumifusawere investigated for involvement of oxidativedamage, cell culture and staining. Also, when OH-Se water extract $100{\mu}g/ml$ was added, the ROS level decreased by 54%. These results indicate that Opuntiahumifusa extracts have an anabolic effect on bone through the promotion of osteoblastic differentiation, suggesting that it could be used for the treatment of common metabolic bone diseases.

The anti-aging and anti-inflammatory activities of hot-water (Ca-HW) and 70% ethanol (Ca-E70) whole-plant Calamagrostis arundinacea extracts, as well as their bioactive potentials, were investigated using cell-free and cell-mediated experimental systems. Use of the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical decolorization assay to evaluate the antioxidant activity of the Ca-HW and Ca-E70 extracts revealed DPPH radical scavenging activities of 27% and 48%, respectively. Neither extract caused significant cytotoxicity, and both showed cell proliferation and promotion effects using RAW 264.7, B16F10, and CCD986sk cells. B16F10 melanoma cells showed higher melanin synthesis when treated with 100 mg/ml Ca-HW or Ca-E70 than with arbutin, indicating a stronger inhibitory effect of arbutin on melanin synthesis. Ca-HW and Ca-E70 increased pro-collagen biosynthesis in the human fibroblast CCD986-SK cell line by 24.69% and 12.55%, respectively. Analysis of the anti-inflammatory effects of different concentrations of Ca-HW and Ca-E70 in RAW264.7 cells revealed that Ca-E70 appeared to inhibit the lipopolysaccharide-induced production of nitric oxide and IL-6, a proinflammatory cytokine; therefore, Ca-E70 showed an anti-inflammatory effect. These results suggested that C. arundinacea extracts could have skin anti-aging and anti-inflammatory properties.
