The purpose of this study was to investigate the anxiolytic-like effect of the methanol extract of Sophorae fructus (MESF) using elevated plus-maze (EPM), open field test, and horizontal wire test in mice. MESF was orally administered at doses of 50, 100, 200, or 400 mg/kg to ICR mice 1 h before behavioral evaluation. The control group was given an equal volume of 10% Tween 80, and the positive control group was given diazepam (1 mg/kg, i.p.). The administration of MESF significantly increased the percentage of time spent in open arms and the entries into the open arms of the EPM compared with the 10% Tween 80-treated control group (p < 0.05). In addition, the anxiolytic-like activities of MESF were antagonized by flumazenil (a GABAA antagonist, 10 mg/kg) but not by WAY-100635 (a 5-HT1A antagonist, 0.3 mg/kg). Futhermore, there were no changes in the locomotor activity and myorelaxant effects of the experimental group, as opposed to the 10% Tween 80-treated control group. Therefore, these findings suggest that MESF promotes the anxiolytic-like activity mediated by the GABAergic nervous system in mice.

Baechu kimchi without cuttlefish (control), baechu kimchi with cuttlefish (CK), cuttlefish baechu kimchi with yogurt (CK+Y), and cuttlefish baechu kimchi with vitamin C (CK+VC) were prepared, and the fermentation characteristics of the prepared kimchi samples were investigated during 28 days of fermentation at 4℃. The levels of moisture, crude lipid, and crude ash did not differ much among the samples, but the crude protein levels of CK, CK+Y, and CK+VC were greater than that of the control. The pH values of CK+Y and CK+VC slowly decreased compared with those of the control and CK during fermentation. The acidity increased sharply until 21 days then gradually increased thereafter. The total microbial counts achieved maximum levels at 21 days, and the kimchi to which yogurt and vitamin C were added showed values lower than that of the control. The number of Leuconostoc sp. in CK+Y and CK+VC was higher than that in the control. In our sensory evaluations, cuttlefish kimchi with yogurt or vitamin C scored highest in terms of texture, sour taste, ripened taste, and overall acceptability.

The purpose of the study was to provide baseline information that could encourage consumers and establish thedirection of development for sprouts and leafy vegetables. A survey on the consumption and preference for sproutsand leafy vegetables of 823 people over 20 years of age in Seoul and Gyeonggi province was conducted. The preference for sprouts was higher in men (3.75±0.96) than in women (3.64±0.84), whereas the preference for leafy vegetables was higher in women (4.06±0.74) than in men (3.88±0.90). Based on age, the respondents in their 40s or above had high preferences for sprouts and leaf vegetables due to the importance that they accorded to health and nutrition (p<0.01). The sprouts and leafy vegetables were purchased mainly for their high nutritional value. The purchase frequency of once a month or more for leafy vegetables (82.7%) was higher than that for sprouts (57.1%). The consumers purchased sprouts and leafy vegetables mainly from a large discount store. The respondents in their 20s showed the highest percentage of purchasing from a local store whereas the older ones showed a high preference for traditional markets. The reason for the choice of the place of purchase was convenience. The freshness and price were important factors in the consumption of sprouts and leafy vegetables. In the case of leafy vegetables, the consumers preferred to buy them using the conventional weight measurement system rather than in small packages. On the other hand, mixed small packages were preferred for sprouts. The purchase frequency was correlated with the preferences, need for improvement and purchase intent for sprouts and leafy vegetables. The aspects that require improvement for producing high-quality sprouts and leafy vegetables were the nutritional and functional properties. To increase the consumption of sprouts and leafy vegetables, there is need for variations and improvement of the quality and safety of the products.

The purpose of this study was to evaluate the anti-atopic-dermatitis effect of Angelica keiskei extract using a DNFB-induced animal model of atopic-dermatitis symptoms. A. keiskei was prepared via extraction with DW, 50% ethanol, and 100% ethanol in addition to fresh juice. All the extracts reduced the thickness levels of the ears and ear epidermis against swelling by DNFB inducement, especially in the aqueous-extract-treated group. The mRNA expressions of matrix metalloproteinases (MMPs), however, were not observed, which may indicate that Angelica keiskei extract alleviates the atopic-dermatitis symptoms in an MMP-independent manner. Finally, the level of the inflammatory cytokine IL-4 was inhibited only in the juice-treated group, although the IL-13 level was inhibited in the juice-, 50%-ethanol-extract-, and 100%-ethanol-extract-treated groups in a dose-dependent manner, and was not inhibited in the aqueous-extract-treated group. Taken together, these results suggest that Angelica keiskei extract has an inhibitory effect on atopic dermatitis, and may be a useful biomaterial for the development of cosmeceuticals.
