The inhibitory effects of cereal extracts and concentrates from barley, waxy rice flours and malt on enzymatic browning were measured using apple polyphenol oxidase (PPO). Malt concentrate showed the largest inhibitory effect on PPO among all. The relationship between the properties of malt concentrate such as browning intensity and reducing power and their inhibitory effect on PPO was also studied. As the heating time increased, the browning intensity and the reducing power of malt concentrates were increased, while PPO activities were decreased. Inhibitory effect of malt concentrates on PPO increased with heating time and their concentration. L-value and compression force of the apple slices dipped in malt concentrate decreased by 6.9% and 14.3%, respectively, showing the smallest changes compared with raw and water-dipped apple slices during cold storage for 9 days. These results suggest that malt concentrate can be a potential source for the control of enzymatic browning.

Background: Recently, substances from seaweeds have been widely used in hair growth solutions, and have been proven to be effective. Seaweeds have been documented to possess hair growth activity; however, no report on the effect of seaweed on hair regeneration has been issued to date. In this study, we investigated which exact substance of hair tonic made by JW-bio and our institute shows effects on hair growth by studying the mechanisms of candidate substances. Methods: The study was conducted to investigate the hair restoring effect of domestic natural substances; we categorized the candidate substances as seaweed, cereal, and herbal medicine. Five experimental groups were included in the study as follows: a saline group, a 50% ethanol group, seaweed group, a cereal group, and a herbal medicine group. Results: Three extracts (seaweed, cereal, and herbal medicine) were administered to C57BL/6 mice for two weeks after depilation. Depilated areas were found to be completely covered with fully grown hair, and the hair re-growth score was highest in the seaweed group. Using a hair analysis system, hair characteristics were measured in all groups on days 10 and 14 after depilation. The width and length of hair follicles were largest in the seaweed group. Groups treated with seaweed showed significantly increased gene expression of insulin-like growth factor-1. Groups treated with all the three extracts showed decreased expression of transforming growth factor-${\beta}1$. Conclusion: Findings from our study suggest that seaweeds possess hair-growth effects and may be useful for the treatment of alopecia in the future.

In order to compare the anti-inflammatory effects of five selected cereal grains-proso millet, hwanggeumchal sorghum, foxtail millet, barnyard millet, and adlay-the inhibitory activities of 80% ethanol (EtOH) extracts obtained from the individual grains on lipopolysaccharide (LPS)-induced nitric oxide (NO) generation were investigated in RAW264.7 cells. The EtOH extract of barnyard millet (Echinochloa crus-galli var. frumentacea) grains exhibited more potent anti-inflammatory activity than that of the other grains. When the EtOH extract of barnyard millet grains was sequentially fractionated with n-hexane, methylene chloride (MC), ethyl acetate (EtOAc), and n-butanol, the majority of the anti-inflammatory activity was detected in the MC fraction, followed by the EtOAc fraction. Pretreatment with the MC fraction caused downregulation of the expression levels of iNOS- and COX-2-specific transcripts and proteins, as well as proinflammatory cytokine gene transcripts (IL-$1{\beta}$, IL-6, and TNF-${\alpha}$) in LPS-stimulated RAW264.7 cells. Additionally, the MC fraction could suppress not only the LPS-induced nuclear translocation of cytosolic NF-kB, but also the LPS-induced activation of MAPKs, such as ERK, JNK, and p38MAPK. Further analysis of the MC fraction by HPLC identified kaempferol, biochanin A, and formononetin as the major phenolic components. Both kaempferol and biochanin A, but not formononetin, could exert anti-inflammatory effect at the same concentrations as those of the MC fraction. Consequently, these results indicate that kaempferol and biochanin A are among the most effective anti-inflammatory phenolic components in barnyard millet grains. This finding suggests that barnyard millet grains and the MC extract enriched in kaempferol and biochanin A could be beneficial functional food sources that have an anti-inflammatory effect.

A new malting barley variety, "Daho", was developed from the cross between "Milyang85 and Suwon335" at the Department of Rice and Winter Cereal Crop (DRWCC) NICS, in 2007. An elite line, YMB2064-B-8-2-4-1-1, was selected in 2004 and designated as "Milyang134". It showed good agronomic performance in the regional adaptation yield trials (RYT) from 2005 to 2007 and was released with the name of "Daho", having high yielding and BaYMV resistance. The average heading and maturing dates of "Daho" were April 19 and May 27, which were 2 days later and 1 day earlier than those of "Jinyang", leading variety, at the regional adaptation yield trials (RYT), respectively. "Daho" had longer culm length (84 cm), more spikes per $m^2$ (915) and higher 1,000 grain weight (39.2 g) than those of "Jinyang" in paddy field condition. "Daho" was showed resistance to BaYMV at the regions of Naju, Jinju, and Milyang but moderately resistance at Iksan. However, the response of "Daho" to other environmental stresses was similar to "Jinyang". The yields of "Daho" at upland and paddy fields were about 5.20 MT/ha, 4.81 MT/ha, respectively, which is about 38%, 25% higher than those of "Jinyang" in the regional adaptation yield trials (RYT), respectively. It has higher grain assortment, germination capacity, water sensitivity and Kolback index but lower malt extract, diastatic power and filtration speed than those of "Jinyang".

To examine the anti-obese activity of miscellaneous cereal grains, 80% ethanol extracts from eight selected miscellaneous cereal grains were compared for their cytotoxic effects on 3T3-L1 murine preadipocytes. The ethanol extract of proso millet exhibited the highest cytotoxicity. Further fractionation of the ethanol extract with methylene chloride, ethyl acetate, and n-butanol showed that the cytotoxicity of the ethanol extract was mainly partitioned into the butanol fraction. As compared with differentiated mature adipocytes, 3T3-L1 preadipocytes were more susceptible to the cyctotoxicity of the butanol fraction. When each organic solvent fraction (25 ${\mu}g/ml$) was added during the differentiation period for 6 days, the cell viability was not affected significantly except for the butanol fraction, but the intracellular lipid accumulation declined to a level of 81.5%~50.3% of the control. The Oil Red O staining data also demonstrated that the ethanol extract as well as the butanol fraction could inhibit the differentiation of 3T3-L1 preadipocytes into mature adipocytes. The presence of the butanol extract during the induced adipocytic differentiation also resulted in a significant reduction in the expression levels of critical adipogenesis mediators $(C/EBP{\alpha}$, $PPAR{\gamma}$, aP2, and LPL) to a barely detectable or undetectable level and the cells retained the fibroblast-like morphology of 3T3-L1. In 3T3-L1 cells, the cytotoxicity of the butanol fraction (50-100 ${\mu}g/ml$) was accompanied by mitochondrial membrane potential (${\Delta}{\psi}m$) loss, caspase-3 activation, and PARP degradation. Taken together, these results indicate that proso millet grains possess pro-apoptotic and anti-adipocytic activities toward adipocytes, which can be applicable to prevention of obesity.
