This research was conducted to investigate the possibilities of usage of germinated-buckwheat (Fagopyrum esculentum $M{\ddot{o}}ench$) by examining antioxidative, antimicrobial and cytotoxic effects of extracts from different germinated root length of buckwheat. Antioxidant activity $(RC_{50})$ was shown higher in extracts of non-germinated seed $(50.41\;{\mu}g/mL)$ and root length 10 mm $(80.57\;{\mu}g/mL)$, 2 mm $(93.77\;{\mu}g/mL)$, 5 mm $(107.09\;{\mu}g/mL)$ than BHT $(163.96\;{\mu}g/mL)$ as a synthetic antioxidant. In antimicrobial activity, non-germinated and germinated seeds were formed inhibitory zone against S. aureus $(4{\sim}10\;mm)$, P. aeruginosa $(2{\sim}9\;mm)$ at the concentrations of $10{\sim}40\;mg/mL$ but B. subtilis, E. coli and S. typhimurium were not apparent antimicrobial activity. Extracts of germinated seed also decreased their antimicrobial activity compared to non-germinated seed extract. In addition, the growth of Calu-6 was inhibited of both 5 mm root length germinated and non-germinated seeds $(800\;{\mu}g/mL)$ as 95.12% and 87.15%, respectively, but these did not show any influence on cytotoxic effect against MCF-7 and Caco-2 cell lines. Extracts of 2 mm and 5 mm germinated seeds were also inhibited against Calu-6 and SNU-601 cell lines.

This study examined metabolic profiles of 1349 Holstein cows from 91 commercial herds. Thirteen parameters which are consisted of twelve blood components and body condition score were examined and their mean values. standard deviations and standard limits, which are 80% confidential limits, in each lactational stage were reported. The variations of each parameter affected by season, individual milk yield, adjusted corrected milk yield of herd. and lactation number were also reported. A model of metabolic profile test applicable to this country where the average number of cows in a herd is small as to be fifteen is designed. Metabolic profiles as reflected in each parameter were discussed in relation to adequacy of dietary intake for production, milk production, reproductive performance, and diseases, and the possible measure to improve productivity of dairy cows were proposed. Much of the variation in parameters was due to differences between herds, and less to differences between seasons, differences between individual milk yield, and differences between lactational stages. As the average herd size in this country is small, it is believed that all the cows in a herd must be sampled, and the individual result of each parameter was compared with the standard limit for each lactational stage, and the percentage of cows which are outside the standard limits in a herd was calculated to use as a criteria for evaluation of the herd. Data outside the 99% confidential limits were to be deleted at first, but when the trends of the data outside the 99% confidential limits are same as the trends of the data within 99% confidential limits, the deleted data must be reviewed again, otherwise some important informations would be missed. The mean concentration of blood urea nitrogen in this study was much higher than that was reported in England, U.S.A. and Japan, and it was similar to the upper limits reported in England, U.S.A. and Japan. So it was thought that the concentration of blood urea nitrogen is improper as a criteria for protein intake. The increase of serum total protein cocentration beyond standard limits was due to increase of serum globulin concentration in most of the cows. The correlation coefficient between serum and protein and serum globulin concentration was 0.83. Serum globulin concentration was negatively related to adjusted corrected milk of herd. Serum albumin, calcium and magnessium concentrations were negatively related to adjusted corrected milk of herd, which indicate that high-producing individual or high-producing herd have not taken sufficient protein/amino acids, calcium and magnessium. Packed cell volume was negatively related to adjusted corrected milk of the herd, and the trend was same In each lactational stage. The correlation coefficient between serum and packed cell volume was 0.16 and the correlation was very weak. Blood glucose concentration was lowest in early lactational stage, which indicates negative energy balance in early lactational stage. Blood glucose concentration was negatively related to adjusted corrected milk of herd from peak to late lactational stage, which indicates negative energy balance during the period in high-producing individuals or high-producing herds. Correlation coefficient between serum aspartate aminotransferase activity and serum ${\gamma}$-glutamyltransferase activity was 0.41, and this indicates that serum ${\gamma}$-glutamyltransferase should be included as a parameter of metabolic profile test to evaluate liver function. Body condition score of dairy cows in this country was lower than that of Japan in every lactational stages, and the magnitude of increase in body condition score during middle and late lactational stages was small. Metabolic profile can not be evaluated with solely nutritional intake. When an individual or large percentage of cows in a herd have adnormal values In parameters of metabolic profile test, veterinary clinician and nutritionist should cooperate so as to diagnose diseases and to calculate the e of no운ents simultaneously.
Objectives: The objective of this study was to evaluate the effects of cytotoxicity, skin regeneration, anti-wrinkle, whitening and skin moisturizing of Oncheongeum (OCE).Methods: The cytotoxicity of OCE lyophilized aqueous extracts (yield=13.82%) was observed against human normal fibroblast cells and B16/F10 murine melanoma cells by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium Bromide (MTT) assay, and skin regeneration and anti-wrinkle effects were also evaluated through the assay of collagen type I synthesis compared to the transformation of the growth factor (TGF)-β1, hyaluronidase, collagenase and matrix metalloproteinase (MMP)-1 inhibitory assays compared to oleanolic acid (OA), and elastase inhibitory effects compared to phosphoramidon disodium salt (PP). In addition, OCE’s whitening effects were measured by a tyrosinase inhibitory assay and melanin formation test in B16/F10 murine melanoma cells compared to arbutin, and skin moisturizing effects were observed through a mouse skin water content test, respectively. Results: No OCE treatment-related cytotoxic effects appeared on human normal fibroblasts and B16/F10 murine melanoma cells. OCE concentration-dependently increased the collagen Type I synthesis on human normal fibroblast cells, and also effectively inhibited hyaluronidase, elastase, collagenase and MMP-1 activities. In addition, OCE inhibited melanin production of B16/F10 murine melanoma cells and activity of tyrosinase. And significant and dose-dependent increases of skin water content were detected in OCE-treated mouse skin compared to vehicle control skins. Conclusions: OCE showed favorable and sufficient effects in skin regeneration, anti-wrinkle, whitening and skin moisturizing in this experiment. But more detail mechanisms and studies on the skin protective efficiency of in vivo are needed with the screening of active biological compounds in individual OCE herbs.
To examine the leaf epidermal microstructure of three genera (Scopolia s.s., Anisodus, AtroPanthe, including Przewalskia as an outgroup) in the genera Scopolia Jacq. s.l., leaves of 10 species (37 specimens) were investigated by the light microscopy (LM) and scanning electron microscopy (SEM). The stomata of studied taxa were 'amphistomatic type' and the size (guard cell) range was $18-64{\times}11-48{\mu}m$. The size of stomata is slightly differed from between the taxa; the smallest size of stomata were found in the monotypic genus, Przewalskia ($24-27{\times}16-17{\mu}m$), on the other hand the largest one was found in Anisodus carniolicoides ($62-64{\times}43-48{\mu}m$). The stomatal complex was mostly anomocytic (in Scopolia s.s., Anisodus taxa : A. luridus, A. carniolicoides, A. acutangulus) and sometimes anisocytic (in Anisodus tanguticus, Przewalskia, Atropanthe). The stomata is mostly crescent in shape, but rarely circular, especially in Przewalskia tangutica. The shapes of epidermal cells are similar in both adaxial and abaxial sides, and mostly undulate/sinuate polygonal anticlinal wall, but rarely arched in Przewalskia tangutica. The epicuticular wax was not well developed in most studied taxa, except Anisodus tanguticus which is well developed cuticular striae around the stomatal complex. The elongate-headed glandular trichomes were found in Scopolia s.s. and Przewalskia. While the taxa of Anisodus and Atropanthe have not any trichomes (i. e., glabrous), except Anisodus luridus, which has simple or sometimes branched (dendritic- type) non-glandular trichome. Finally, the systematic and ecological significance of the leaf micromorphological features (stomata complex, trichome, etc.) in identification and elucidation of Scopolia s.l. including Przewalskia, especially between or within the genera including among the species is also discussed.
This study was carried out to investigate the cleaning effect of sesame leaf, the sterilization effect and physicochemical properties, treated with various electrolyzed water. Initial physicochemical properties could be kept more than 1 month in electrolyzed oxidizing water(EW-1) of diaphragm type and 15 days in electrolyzed water(EW-2 and EW-3) of non-diaphragm system, there was no significant difference by storage temperature. 4 kinds of microorganism (initial total counts, $10^7\~10^9$ CFU/mL) were sterilized within $0.5\~1$ minutes by electrolyzed water. In fresh sesame leaves, total viable cell count and coliform group in the treatment of electolyzed water were decreased to about $2\~3$ log scale comparing non-treated ones. Especially Bacillus cereus was not detected until 13th day when treated with EW-l. Decaying ratio of sesame leaf appears on day 6 of storage in the untreated but the treatments of electrolyzed water has no sign until day 10 of storage. Change in color difference(${\Delta}E$) during storage was observed the treatments of electrolyzed low-alkaline water(EW-2) and electrolyzed neutral water(EW-3) were very desirable at the level $1\~2$ after day 13 of storage comparative to the untreated Change of Chlorophyll content was biggest decreased to 6.8 $mg\%$ on the untreated and decreased least to 8.35 $mg\%$ on EW-3 treated group on 13th day from initial value of $9.0\~10.3\;mg\%$ The overall sensory evaluation appeared most acceptable in the treatments of EW-2 and EW-3.
The observations on the spatio-temporal distribution and seasonal fluctuations of phytoplankton community were carried out in Deukryang Bay of the Korean Southwestern Sea from June 1992 to April 1993. A total of 75 species of phytoplankton belonged to 47 genera was identified. In Deukryang Bay seasonal succession in dominant species; P. alata, G. flaccida, S. costatum, L. danicus and N. longissima in summer, St. palmeriana, Ch. curvisetus and B. paxillifera in autunm, S. costatum, Ch. curvisetus, E. zodiacus and Pn. pungens in winter, and As. glacialis, As. kariana, N. pelagica, Th. nitzschioides and S. costatum in spring, were very marked, that is to say, the communities structure of phytoplankton in Deukryang Bay appeared to be various species composition and it was occupied with diatoms all the year round. Phytoplankton standing crops fluctuated with an annual mean of $1.4{\times}10^5 cells/1 between the lowest value of 2.6{\times}10^3 cells/1 in July and the highest value of 1.0{\times}10^6 cells/1$ by S. costatum in January. Densities of the phytoplankton cell number by the samples of Deukryang Bay ranged from $2.6{\times}10^3cells/1 to 1.2{\times}10^5 cells/1 with the mean value of 3.6{\times}10^4cells/1 in summer, from 6.0{\times}10^3cells/1 to 2.6{\times}10^5 cells/1 with mean of 1.5{\times}10^5 cells/1 in autumn, from 1.3{\times}10^4cells/1 to 1.0{\times}10^6 cells/1 with mean 3.5{times}10^5 cells/1 in winter, and from 4.8{\times}10^3cells/1 to 6.0{\times}10^5 cells/1 with mean of 1.6{\times}10^5 cells/1$ in autumn. That is to say, phytoplankton standing crops was large in low temperature seasons, on the other hand small in high temperature seasons. Chlorophyll $\alpha$ concentration fluctuated between 0.l9 $\mu$g/l and 12.3 $\mu$g/l in March. in Deukryang Bay seasonal flucturation in chi-$\alpha$ concentration was not marked. Especially, chl-$\alpha$ concentration in the water around Deukryang Island located in the middle part of Deukryang Bay showed patchy distributions with a very high concentration. And chl-$\alpha$ concentration was high during a year. Therefore, phytoplankton production in Deukryang Bay could be very high year-round.

Effects of mistletoe (Viscum album) extract and pueraria (Pueraria radix) extract on cellular NF-$textsc{k}$B activity were evaluated in human malignant keratinocytes (SCC-13) to elucidate the possible correlation of NF-$textsc{k}$B with antioxidant activity. The antioxidant activities of these natural extracts were examined in four different evaluation methods, i.e., lipid peroxidation value (POV) evaluation test, I,l-diphenyl-2-picrylhydrazyl radical (DPPH), nitric oxide (NO) scavenging test, and reducing power assay. Pueraria extract (0.5 mg) and mistletoe extract (5 mg) downregulated the cellular NF-$textsc{k}$B activation up to 35% and 10% compared to the control, respectively, although their effects were lower than the known NF-$textsc{k}$B downregulator, vitamin C (8.8 mg, 53%) in a cell-based NF-$textsc{k}$B activity assay system. In the POV test, relative antioxidant activities of mistletoe extract (86%) and pueraria extract (75%) were significantly higher than the known antioxidant, vitamin C (48%) at the same concentration (10 mg) and the degree of activity increased in a dose-dependent manner. Pueraria extract showed more potential radical scavenging activities than those of mistletoe extract evaluated in both DPPH and NO test. Especially, the NO radical scavenging activity of pueraria extract ($SC_{50}$/, 88 $\mu$g) was comparable to that of vitamin C ($SC_{50}$/, 77 $\mu$g). Even pueraria extract possessed a much less reducing power compared to vitamin C, it also revealed higher reducing power than that of mistletoe extract. These results indicate that mistletoe extract and pueraria extract may serve as an useful natural antioxidant agents, and led to suggest the hypothesis that compounds having an antioxidant activity, i.e., radical scavenging activity or reducing power may be correlated with the downregulation of NF-$textsc{k}$B activation in human keratinocytes.
The present study was performed to investigate antioxidant, anticancer, and antimicrobial activities of four Korean sweet potato variaties and to identify the changes in these biological activities under different cooking conditions. Total polyphenol content was 3.8-73.6 mg/g in 80% ethanol extracts of sweet potatoes. The polyphenol content was highest Sinjami variety (p < 0.05). Radical scavenging activity against DPPH and $ABTS^{{\cdot}+}$ was high in Sinjami (p < 0.05) and the ethanol extract from Sinjami also showed effective superoxide dismutase (SOD)-like activity, which decreased significantly by steaming and roasting (p < 0.05). Ethanol extracts from the four sweet potato variaties did not inhibit cancer cell growth in MCF-7 or HepG2 cells at concentrations of 1, 10, and $100\;{\mu}g$/mL. Of the investigated sweet potato variaties, only Sinjami exhibited strong antimicrobial activity against Escherichia coli, Staphylococcus aureus, and Salmonella typhimurium. The antimicrobial activity of Sinjami against E. coli, St. aureus, and S. typhimurium decreased following steaming and roasting (p < 0.05). These results indicate that the Sinjami Korean sweet potato had higher polyphenol content, radical scavenging activity, SOD-like activity, and antimicrobial activity than those of the other variaties and consuming raw Sinjami might be beneficial for maintenance of biological activities.

Nerium indicum, an India-Pakistan-originated shrub belonging to the oleander family, is reported to possess many pharmacological activities including cardiac muscle stimulation, and anti-diabetes, anti-angiogenesis, anti-cancer and neuro-protective activities. However, the anti-inflammatory properties of N. indicum were unclear. In this study, we investigated the effects of ethanol extract of the N. indicum leaf and stem (ENIL and ENIS) on the expression of anti-inflammatory mediators in U937 human pre-monocytic cell models. In U937 cells stimulated with phorbol 12-myristate-13-acetate (PMA), pre-treatment with ENIS significantly inhibited the expression of both cyclooxygenase-2 (COX-2) mRNA and protein, which are associated with inhibition of the release of prostaglandin $E_2\;(PGE_2)$, whereas the inhibitory effects appeared weakly in ENIL. Moreover, ENIS significantly attenuated PMA-induced IkappaB ($I{\kappa}B$) degradation and suppressed elevated nuclear factor kappa B (NF-${\kappa}B$) nuclear translocation. Taken together, these findings provide important new insights that N. indicum exhibits anti-inflammatory properties by suppressing the transcription of pro-inflammatory cytokine genes through the NF-kB signaling pathway.
The purpose of this study was to confirm the exactitude of in vitro nuclear magnetic resonance spectroscopy(NMRS) and to complement the defect of in vivo NMRS. It has been difficult to understand the metabolism of a cerebellum using in vivo NMRS owing to the generated inhomogeneity of magnetic fields (B0 and B1 field) by the complexity of the cerebellum structure. Thus, this study tried to more exactly analyze the metabolism of a canine cerebellum using the cell extraction and high resolution NMRS. In order to conduct the absolute metabolic quantification in a canine cerebellum, the spectrum of our phantom included in various brain metabolites (i.e., NAA, Cr, Cho, Ins, Lac, GABA, Glu, Gln, Tau and Ala) was obtained. The canine cerebellum tissue was extracted using the methanol-chloroform water extraction (M/C extraction) and one group was filtered and the other group was not under extract processing. Finally, NMRS of a phantom solution and two extract solution (90% D2O) was progressed using a 500MHz (11.4 T) NMR machine. Filtering a solution of the tissue extract increased the signal to noise ratio (SNR). The metabolic concentrations of a canine cerebellum were more close to rat’s metabolic concentration than human’s metabolic concentration. The present study demonstrates the absolute quantification technique in vitro high resolution NMRS with tissue extraction as the method to accurately measure metabolite concentration.
