  • Lactic acid bacteria (LAB) are typical probiotic microbes which are used in various industries including fermented foods, feed additives, and pharmaceuticals. The purpose of this study was to compare the ability of antioxidative activities of 23 strains of LAB isolated from cheese, kimchi, yogurt, and etc. LAB were tested for antioxidative activities such as 2,2'- azino-bis(3-ethyl-benzothiazoline-6-sulphonic acid) (ABTS) radical scavenging abilities and superoxide dismutase (SOD)-like ability. Antioxidative activities were examined different media such as MRS, M17, and 10% skim milk. Culture supernatant in M17 medium showed a higher antioxidative activity than these in MRS and 10% skim milk. Comparison of ABTS radical scavenging ability by the LAB showed a wide variation with a range from 9~93% and SOD-like ability of LAB ranged from 70~78%, respectively. Therfore, some of LAB can play important roles in the protection for oxidative stress and CPP-producing activity of LAB may be a promising material for application in the dairy industry.

  • Objectives: The purpose of this study is to evaluate the effects of Gamiguibi-hwan on Climacteric Syndrome. Method: We treated 50 cases menopausal disorder patients with Gamiguibi-hwan for 12 weeks. We estimated the effects by Menopause Rating Scale (MRS), Pittsburgh Sleep Quality Index (PSQI) and Beck's Depression Inventory II (BDI-II). Results: After treatment, the mean of MRS, PSQI and BDI-II score were decreased. Conclusions: This case shows that Gamiguibi-hwan is effective in treating menopausal disorder patients.

  • To examine stability and a separate quantitative method of a mixed preparation of lactic acid bacteria, a capsule containing Lactobacillus acidophilus, Lactobacillus bulgaricus and Streptococcus thermophilus was suspended and diluted in sterile water. After the diluted suspension was spread on three media of tryptone glucose extract agar, MRS agar and MRS-sucrose agar, their colonies appeared and were counted. The viable counts exceeded the minimum number of the three bacteria and showed that the mixed preparation was stable at least for 18 months. The results also showed that a separate quantitation of viable cells of the each strain was feasible.

  • Relativization is one of the common syntactic operations to merge two different clauses into a single information unit. This operation plays a pivotal role to structuralize multiple clauses cohesively as well as serves to specify the property an individual has within the context. That implies that relativization contributes to information structure of multiclausal sentences. In this context, this paper delves into information structure of relative clauses in English with an eye toward creation of a computational model from a standpoint of machine translation. The current work employs Head-driven Phrase Structure Grammar (HPSG, Pollard and Sag (1994)) as a theory of grammar and Minimal Recursion Semantics (MRS, Copestake et al. (2005) as a meaning representation system. Building upon these formalisms, this paper addresses how information structure of relative clauses can be represented and constrained. The current work makes use of Individual CONStraints (ICONS) for modeling relative clauses with respect to information structure. The current work also investigates which relative clause involves which information structure constraint. The present study argues that non-restrictive relative clauses impose a more specific constraint on information structure than restrictive relative clauses.

  • Effect of galactooligosaccharides produced by the $\beta$-galactosidase from Aapwefillua niger CAD 1 on the growth of Bifidobacterium infantis KCTC 3127 Bifidobacterium longum KCTC 3128 and Bifidobacterium bif-idum ATCC 11863 were investigated. Bifidbacterium infantis Bifidobacterium longum and Bifidobacterium bif-idum were in the logarithmic growth phase after 6hr incubation at 37$^{\circ}C$. Bifidobacterium infantis was in the stationary phase after 24hr incubation at 37$^{\circ}C$. The growth rate of B. bifidum containing galactooligo-saccharides and raffinose in MRS broth increased up to 18%, 8% and 7% compared to glucose galac-tose and lactose during 48hr incubation. The growth rate of B. infantis and B. longum contatining galacto-oligosaccharides and raffinose in MRS broth increased up to both 6% and 8% and both 13% and 10% compared to glucose and galactose during 48hr incubation.

  • 2-Month-old, three related Perro de Presa Canario dogs were evaluated for similar neurological symptoms like circling, head pressing, depressed mental status, hypermetria, and vocalization. On magnetic resonance imaging (MRI) of the brain, there were large, bilaterally symmetrical lesions with involvement of thalamus, and brainstem that were T2- and FLAIR-hyperintense and T1-iso/hypointense. There was no inclusion of cerebellum. Single-voxel spectroscopy acquisition was located in the thalamus where abnormalities were found in MR images. The results of magnetic resonance spectroscopy (MRS) showed markedly decreased N-acetylaspartic acid value. Euthanasia was performed and lesions consistent with the canine spongy degeneration. Alteration in metabolites in the brain can be determined by MRS, which helps in diagnosing degeneration/leukodystrophy of the central nervous system in dogs.

  • Listeria monocytogenes is a representative foodborne pathogen and causes listeriosis. Enterococcus faecium CJNU 2524 was confirmed to produce a bacteriocin with anti-listerial activity. To establish optimal culture conditions for the production of the bacteriocin from E. faecium CJNU 2524, different media (MRS and BHI broth) and temperatures (25℃, 30℃, and 37℃) were investigated. The results showed that the optimal culture conditions were MRS broth and 25℃ or 30℃ temperatures. The crude bacteriocin was stable in a broad range of pH conditions (2.0-10.0), temperatures (60℃-100℃), and organic solvents (methanol, ethanol, acetone, acetonitrile, and chloroform). The bacteriocin activity was abolished when treated with protease but not α-amylase or lipase, indicating the proteinaceous nature of the bacteriocin. Finally, the bacteriocin showed a bactericidal mode of action against L. monocytogenes. Therefore, it can be a biopreservative candidate for controlling L. monocytogenes in dairy and meat products.

  • This case study reports on the effectiveness of Korean medicine treatment for menopausal hot flashes in stroke patients. During hospitalization, a female patient with medial medullary infarction was diagnosed with menopausal hot flashes and received treatment with traditional Korean medicine and acupuncture. The assessment was performed by monitoring daily habits to relieve hot flashes. The hot flash index, menopause rating scale (MRS), menopause-specific quality of life (MENQoL) questionnaire, and Kupperman index (KI) were also used. After 28 days of treatment, the hot flash index improved from 27 to 2, MRS improved from 11 to 2, MENQoL improved from 40 to 21, and KI improved from 22 to 6. Thus, this case suggests that Korean medicine treatment may be effective for menopausal hot flashes in stroke patients.
