Fish patty is a product spotlighted recently in the application area of functional food because its main ingredients are soybean and fish with various functions which make it highly digestible, tasty, rich with protein and calcium, and with low fat. Thus, in order to optimize fish patties, this study analyzed their water content, colors, texture and sensory characteristics according to the addition of soybean powder. As a result, water content and lightness decreased with the increase of the addition of soybean powder while hardness, elasticity, chewiness, and gumminess increased with the increase of the addition of soybean powder. Among sensory characteristics, taste, chewiness and texture were highest in S2, and in general evaluation, S2 received the highest score. Thus, S2 was found the most appropriate addition of soybean powder in making fish patties. Based on the results of this study, if fish patties to which soybean powder is added can be used in hamburgers and other food products for the diversity, functionality, and high quality of processed food products using soybean and fish, people's appreciation of hamburgers will be changed, and this will bring a new turning point to the consumption of hamburgers. Furthermore, it is believed that the development of healthy patty-type soybean powder products may resolve worries about fast food and quality-related and health-related problems in hamburger patties.

We investigated ${\alpha}$-amylase, ${\alpha}$-glucosidase and lipase inhibitory activity of extracts collected from wild plants in Gangwon-do. 90 wild plants were collected and their water and ethanol extracts were obtained. Results of measuring ${\alpha}$-amylase inhibitory activity indicated more than 80% of activity inhibition in 10 mg/mL concentration for ethanol extracts of three plants and water extracts of two plants. For ${\alpha}$-glucosidase inhibitory activity, ethanol extracts of thirteen plants and water extracts of three plants showed more than 80% of activity inhibition in 10 mg/mL concentration. In the experiment of inhibiting lipase activity, ethanol extracts of seven plants and water extracts of one plants showed above 80% of activity inhibition in 10 mg/mL concentration. These results suggest that the selected extracts could be potentially used as a resource of bioactive materials for health functional foods.
Objectives Non-major depression with fewer symptoms than required for a Diagnostic and Statistical Manual of Mental Disorders-4th edition diagnosis of major depressive disorder (MDD) has consistently been found to be associated with functional impairment. In this study, we aim to estimate the cognitive impairment and the quality of life in elderly patients with subsyndromal depression (SSD) compared with non-depressive elderly (NDE). Methods The Korean version of Mini International Neuropsychiatric Interview was administered to 194 outpatients with depression and 108 normal controls. SSD is defined as having five or more current depressive symptoms with core depressive symptoms (depressive mood or loss of interest or pleasure) during more than half a day and more than seven days over two weeks. Depression was evaluated by the Korean form of Geriatric Depression Scale of a 15-item short version. Global cognition was assessed by Mini-Mental State Examination in the Korean version of CERAD assessment packet (MMSE-KC). Subjective cognitive impairment was assessed by the Subjective Memory Complaint Questionnaire. Quality of life was evaluated by the Korean Version of Short-Form 36-Item Health Survey. Results The mean score of the MMSE-KC in the SSD group was lower than that in the NDE group with adjustment for age, gender, and education [F = 4.270, p = 0.04, analysis of covariance (ANCOVA)]. If we defined those having Z-score of MMSE-KC < -1.5 as a high risk group of cognitive impairment, the odds ratio for the high risk group of cognitive impairment was 1.86 [95% confidence intervals (CI) 1.04-3.34] in SSD and 7.57 (95% CI 3.50-16.40) in MDD compared to NDE. The scores of physical component summary (F = 9.274, p = 0.003, ANCOVA) and mental component summary (F = 53.166, p < 0.001, ANCOVA) in the SSD group were lower than those in the NDE group with adjustment for age, gender, and education. Conclusions The subjects with SSD, as well as those with MDD, showed impairment of global cognition and also experienced low quality of life in both physical and mental aspects, compared to the NDE group.
Kefir, which originates in the Caucasian mountains, is a cultured milk beverage produced by a combination of acidic and alcoholic fermentation. Kefir products are commonly used as food vehicles to deliver health-promoting materials including kefran and lactic acid bacteria to consumers. The aim of this study was to develop a freeze-dried starter culture without yeast and assess the suitability of kefir-like dairy products for the growth of lactic acid bacteria and the acidification of milk. Pasteurized whole milk (SNF 8.5%) stored at $25^{\circ}C$ was aseptically inoculated with starter cultures (0.002% w/v); it was kept at $25^{\circ}C$ until the pH attained a value of 4.6. Ten grams of the kefir-like product sample was diluted with 90 mL of 0.15% peptone water diluent in a milk dilution bottle, followed by uniform mixing for 1 min. Viable cells of Lactobacillus species were enumerated on modified-MRS agar (pH 5.2), with incubation at $37^{\circ}C$ for 48 h. Viable cells of Lactococcus species were enumerated on M17-lactose agar, with incubation at $32^{\circ}C$ for 48 h. The pH attained a value of 4.6 after fermentation for 9 h 30 min (Starter 1), 9 h 45 min (Starter 2), and 12 h (Starter 3). The viable cell count of Lactobacillus sp. and Lactococcus sp. was initially $10^5{\sim}10^6CFU/g$; it increased significantly to $10^9CFU/g$ after 12 h of incubation. During the storage of the kefir-like products at $4^{\circ}C$ for 1 4 days, the total viable cell numbers were unchanged, but the pH decreased slightly. The consistency of the kefir products increased gradually during the storage. The organoleptic properties of the kefir products fermented using the new starter culture are more desirable than those of commercial kefir. These results suggest that the newly developed starter culture without yeast could be suitable for kefir fermentation.
This study was carried out to determine the inhibitory effects of methanol extracts from Korean Orysa sartiva and Coix lachryma-jobi var. ma-yuen on mutagenicity using Ames test and growth of AGS human gastric adenocarcinoma and HT-29 human colon cancer cells. Both treatments of methanol extracts (5 mg/assay) from Orysa sartiva and Coix lachryma-jobi var. ma-yuen to Ames test system inhibited aflatoxin $B_1$ ($AFB_1$) induced mutagenicity by 76%. In case of N-methyl-N'-nitro-N-nitrosoguamidine (MNNG) induced mutagenicity, the methanol extracts (5 mg/assay) from Orysa sartiva and Coix lachryma-jobi var. ma-yuen showed 79% and 69% inhibitory rate, respectively and the inhibitory effect was a little stronger in Orysa sartiva Inhibitory effects of methanol extracts from Orysa sartiva. and Coix lachryma-jobi var. ma-yuen on the growth of AGS and HT-29 human cancer cells were increased as dose dependent patterns and the inhibitory effects on AGS and HT-29 cells were similar. The above results indicate that the consumption of these cereals, which contain many nutrients with good quality, may be recommended as potent functional foods for improving health.

The aim of this study was to investigate the potential effects of extracts from silkworm (Bombyx mori L.) that was fermented with Bacillus subtilis KACC 91157 at the levels of 1%(v/w), 2.5%(v/w), and 5%(v/w) in alcohol-fed rats. Sprague-Dawley rats were divided into seven groups: normal group (N), alcohol treated group (C), silymarin treated group (PC, positive control), 5% silkworm powder treated group (SP5), 1% Bacillus subtilis-fermented silkworm powder treated group (BSP1), 2.5% BSP treated group (BSP2.5), and 5% BSP treated group (BSP5). The activities of AST, ALT, ALP, and LDH in the serum and the triglyceride concentrations in the liver and serum were increased by alcohol feeding but were reduced in the BSP5 group. In addition, the contents of total lipids, free fatty acids, and total cholesterol were increased in the alcohol-fed group but were reduced in the BSP5 group. The activities of ADH, ALDH and ADH, ALDH protein levels in the liver were increased in the BSP5 group. The TBARS contents in the liver, serum, liver mitochondria, and liver microsomes were slightly decreased in the BSP5 group compared to the C group. The hepatocytes in alcohol-fed rats contained numerous large droplets; however, BSP5 treatment prevented alcohol-induced lipid droplet accumulation in the hepatocytes. Based on these results, extracts from Bacillus subtilis-fermented silkworm (Bombyx mori L.) have significant potential for development into a functional health food that can improve alcoholic fatty liver conditions.

Hemp seed (Cannabis sativa L.; HS), an annual herbaceous plant in the Cannabis genus, has been reported to play various biological functions in immunity increase, atherosclerosis, constipation, hyperlipidemia prevention, anti-inflammatory, and anti-cancer. In recently years, as superfood, the growing interest in the health care benefits of hemp seed has led to increased consumption. In this study, we investigated the effect of an ethanol extract of HS fermented with lactic acid bacteria (Lactobacillus plantarum KCTC 3107, L. plantarum KCTC 3108, L. brevis BHN-LAB128, L. paracasei BHN-LAB129). An antibacterial activity against Staphylococcus aureus and Bacillus cereus were 13.99 mm and 15.17 mm, respectively. The ethanol extracts of fermented hemp seed by lactic acid bacteria that the contents of total polyphenol, total flavonoid content, DPPH radical scavenging activity, SOD-like activity, and ${\alpha}$-glucosidase inhibitory activity were increased compared to non-fermented hemp seed. Also, tyrosinase inhibitory activity of the fermented hemp seed (FHS), known to melanin increasing substance was increased. In these results, we suggested that FHS have effects of anti-oxidant, ${\alpha}$-glucosidase inhibitory activity, and tyrosinase inhibitory activity. Hence, we proposed that FHS has possible to development as functional foods and cosmetics.

Hepatitis C virus (HCV) propagation is highly dependent on cellular proteins. To identify the host factors involved in HCV propagation, we previously performed protein microarray assays and identified the LIM and SH3 domain protein 1 (LASP-1) as an HCV NS5A-interacting partner. LASP-1 plays an important role in the regulation of cell proliferation, migration, and protein-protein interactions. Alteration of LASP-1 expression has been implicated in hepatocellular carcinoma. However, the functional involvement of LASP-1 in HCV propagation and HCV-induced pathogenesis has not been elucidated. Here, we first verified the protein interaction of NS5A and LASP-1 by both in vitro pulldown and coimmunoprecipitation assays. We further showed that NS5A and LASP-1 were colocalized in the cytoplasm of HCV infected cells. NS5A interacted with LASP-1 through the proline motif in domain I of NS5A and the tryptophan residue in the SH3 domain of LASP-1. Knockdown of LASP1 increased HCV replication in both HCV-infected cells and HCV subgenomic replicon cells. LASP-1 negatively regulated viral propagation and thereby overexpression of LASP-1 decreased HCV replication. Moreover, HCV propagation was decreased by wild-type LASP-1 but not by an NS5A binding-defective mutant of LASP-1. We further demonstrated that LASP-1 was involved in the replication stage of the HCV life cycle. Importantly, LASP-1 expression levels were increased in persistently infected cells with HCV. These data suggest that HCV modulates LASP-1 via NS5A in order to regulate virion levels and maintain a persistent infection.

This study aims at helping cerebrally palsied children to overcome and minimize their sufferings, inducing them to perform ordinary activities of daily living for themselves by coducting ADL Tests which are fundamental activities in daily life and presenting treatment plan for their overall rehabilitation and basic data for achieving the training objective. For that purpose, 173 cerebrally palsied children were selected and given ADL performance Tests from Dec. 1987 to Oct. 1988 and the following results were obtained. 1. Correlation coefficients for each ADL category indicated significant statistical value at .01 level. 2. Correlation coefficient between school-year variable and ADL category variable was significant at .01 level. 3. Correlation between age variable and ADL variable category proved significant at .01 level as well. 4. Correlation coefficients between each category in terms of functional state of extremities were significant at .01 level. 5. The difference in ADL achievements between each category by school year were as follows ; 1) In the category of meeting nature's tall, the age span of more than 4 school years showed statistical significance. 2) In the category of putting off and on clothing, the age span of 3 school years indicated statistical significance. 3) In taking meals statistical significance was found in the age span of 4 school years. 4) In finger movements the age span of more the 4 school years indicated statistical significance. 5) In walking activities statistical significance was noticed in the age span of 2 or 3 school years. Besides, in category by school year, and exceptional case was noticed that the 6th graders were lower than the 5th graders in self-reliance rate. 6. the difference in ADL achievements by type of palsy, children of triplegia were the lowest, while those of monoplegia were the highest. 7. The difference in ADL achievements by kind of palsy, patients of athetosis showed lower rate of self-reliance than those of spasticity, and particularly the latter showed a high rate of self-reliance in taking meals$(83.5\%)$. The former were relatively low in self-reliance and lowerst in meeting nature's call $(59.8\%)$.
This study aims to identify the chemical compositions and antioxidant activities of essential oil, extracted from the leaves of Neolitsea aciculata (Blume) Koidz by the hydrodistillation method. To the end, the chemical composition of N. aciculata leaf oil was firstly analyzed through GC/MS. The major constituents of essential oil were found to be: cis-ocimene (11.00%), trans-ocimene (9.65%), elemol (9.15%), ${\beta}$-elemene (8.75%), germacrene-D (7.55%), trans-caryophyllene (5.90%), ${\gamma}$-elemene (5.40%) and ${\tau}$-muurolol (4.95%). Then, the antioxidant potential of the essential oil was evaluated by the methods of total polyphenolic content (TPC) assay, DPPH radical scavenging activity, ABTS radical scavenging activity and ferric reducing antioxidant power (FRAP). It was estimated that the total polyphenolic content of the oil was $136.7{\pm}0.13\;mg\;GAE/g$ and the efficient concentration of the oil required to scavenge 50% DPPH radicals ($EC_{50}$ value) was $639.33\;{\mu}g/m{\ell}$. Also, ABTS radical scavenging activity was identified to be concentration dependent, while the FRAP value was $31.21{\pm}0.12\;{\mu}M$$FeSO_4{\cdot}7H_2O/g$. Such figures, as a result, suggest that the essential oil extracted from the leaves of N. aciculata has its antioxidant activity, which can serve as significant health functional benefits.
