Objectives : The purpose of this study is to assess the effect of Daekumeumja herb-acupuncture on neural cell proliferation and nitric oxide synthase(NOS) expression in hippocampus of ethanol-intoxicated Sprague-Dawley(SD) rats. Methods : SD rats were randomly assigned into 5 groups ; the normal group, the alcohol-treated(control) group, the alcohol- and 1 mg/kg Daekumeumja- treated(sample A) group, the alcohol- and 5mg/kg Daekumeumja-treated (sample B) group, the alcohol- and 10 mg/kg Daekumeumja-treated (sample C) group(n = 6 in each group). Normal group were received with Saline, while control group were injected intraperitoneally with alcohol(2 g/kg) once per day for 5 days. Sample groups were treated Daekumeumja herb-acupuncture on Chungwan(CV12) for 5 consecutive days. Bromo-deoxyuridine(BrdU) was injected into all animals once per day for 5 days. For the detection of BrdU-positive cells and NADPH-d- positive cells in hippocampus, immunohistochemistry was performed. Results : 1. In the dentate gyrus area, the number of BrdU-positive cells in the sample $B(278.08{\pm}6.46)$, $C(331.33{\pm}16.68)$ groups was significantly(p<0.05) increased compared with the control group. 2. In the dentate gyrus area, the number of NADPH-d-positive cells in the sample $C(86.50{\pm}10.02)$ groups was significantly(p<0.05) increased compared with the control group. 3. In the CAI area, the number of NADPH-d-positive cells in the sample $A(63.90{\pm}2.69)$, $B(75.70{\pm}3.01)$, $C(97.70{\pm}4.06)$ groups was significantly(p<0.05) increased compared with the control group. 4. In the CA 2-3 area, the number of NADPH-d-positive cells in the sample $B(30.20{\pm}1.89)$, $C(62.70{\pm}2.08)$ groups was significantly(p<0.05) increased compared with the control group. Conclusion : These results indicate that, neural cell proliferation and NOS expression in hippocampus was reduced in ethanol-intoxicated group. Treatment of Daekumeumja herb-acupuncture increased this diminution. Daekumeumja could be able to effect on the prevention of the amnesia and learning disability in alcoholism.

This study was conducted to investigate the kinds of health promotion program which workers want, worker's intention for participation, proper method, time, duration and manager. A self-administered questionnaire method was used to collect data from 412 employees of 3 worksites in Chungpook and Kyungkee. This survey was carried out from Aug. 10 to Aug. 20, 1998. The results of this study are as follows: 1. In male, among health promotion programs, favorite ones were physical fitness(32.2%), periodic health check-up(24.6%), and stress management(18.0%). In female, among health promotion programs, favorite ones were periodic health check-up(26.0%), physical fitness(22.0%), and body weight control(19.5%). 2. The more young subjects are, the more they like physical fitness program, and the female like body weight control program regardless of BMI. Manufacturing worker preferred back pain prevention program to clerical worker did. In female, drinker preferred stress management program to non-drinker did. 3. The more old subjects are, the more they like back pain prevention program, and non-smoker preferred body weight control program to smoker did. 4. In health promotion program format which the subjects wanted, learning of self-examination techniques was 41.1%, worksite screening was 3l.0%, availability of pamphlets and audiovisual materials was 20.0%, presentation of worksite educational sessions was 7.9%, and the most wanted manager for the program was medical doctor and then nurse, physical trainer, psychological counselor. The favorite health promotion program duration was less than 30 minutes(49.6%), and the favorite time was before work(49.6%). 5. Among respondents, 48.5% was smokers, 81.8% was drinkers, 39.9% engaged in the regular exercise, 68.2% engaged in regular diet habit. In vaccination, 50.2%, if possible, wanted to be vaccinated and 37.6% never wanted to be vaccinated. 6. Ex-smoker, ex-drinker, the subjects in the regular exercise, and in the regular diet habit responded they were in good health. There was a significant difference between exercise and health status. Need and intention for participation of health promotion program were high in ex-smoker, ex-drinker, the subjects in the regular exercise, and in the regular diet habit. According to results for this study, if the favorite programs, exercise, periodic health check-up, stress management program, are operated at a proper time and with managers they want, this programs can really raise the participation of employees. And as employees want to learn self-examination techniques if worksite educational sessions are performed, health promotion program can effectively be operated.

The rhizomes of Cnidium officinalis were extracted in aqueous MeOH, and the concentrate was fractionated via systematic solvent fractionation to EtOAc, n-BuOH, and aqueous fractions. The repeated column chromatography of EtOAc and n-BuOH fractions using silica gel, octadecyl silica gel, and Sephadex LH-20 as stationary phase to afford five lipids. They were identified to be methyl linoleate (1), linoleic aicd (2) 6-linoleoyl-𝛼-D-glucopyranosyl 𝛽-D-fructofuranoside (3), 1-linolenoyl-3-(𝛼-D-galactopyranosyl (1→6)-𝛽-D-galactopyranosyl) glycerol (4), and 1-linoleoyl-3-(𝛼-D-galactopyranosyl (1→6)-𝛽-D-galactopyranosyl) glycerol (5) on the basis of spectroscopic data such as IR, MS, and Nuclear magnetic resonance (NMR). Compounds 1 and 3-5 were isolated for the first time from this plant in this study. The NMR data of fatty acids 1 and 2 reported in literatures are different each other. Authors identified the NMR data without ambiguity. Compound 3, a conjugate of sucrose and fatty acid, and compounds 4 and 5, digalactosyl monoglyceride, are very rarely occurred in natural source. Through the immune enhancement and anticancer activity of the reported lipid compounds, the potential as various pharmacologically active materials of Cnidium officinalis rhizome can be expected.

Objective: Chronic obstructive pulmonary disease(COPD) is characterized by persistent airflow limitations associated with chronic inflammatory response due to noxious particles or gases in the lung. Inflammation and oxidative stress are associated with COPD. The aim of this study was to evaluate the relationship among inflammation, oxidative stress, and airflow limitation severity in retired miners with COPD. Methods: The levels of serum high-sensitivity C-reactive protein(hsCRP) as a biomarker for inflammation, degree of reactive oxygen metabolites(dROMs) and biological antioxidants potential(BAP) in plasma as biomarkers for oxidative stress were measured in 211 male subjects with COPD. Degree of airflow limitation severity as determined by spirometry was divided into three grades grouped according to the classification of the Global Initiatives for Obstructive Lung Disease(GOLD)(1, mild; 2, moderate; $3{\leq}$, severe or more) using a fixed ratio, post- bronchodilator $FEV_1/FVC$ < 0.7. Results: Mean levels of dROMs significantly increased in relation to airflow limitation severity(GOLD 1, 317.8 U.CARR vs. GOLD 2, 320.3 U.CARR vs. GOLD $3{\leq}$, 350.9 U.CARR, p=0.047) and dROMs levels were correlated with serum hsCRP levels(r=0.514, p<0.001). Mean levels of hsCRP were higher in current smokers(non-smoker, 1.47 mg/L vs. smoker, 2.34 mg/L, p=0.006), and tended to increase with degree of airflow limitation severity(p=0.071). Mean levels of BAP were lower in current smokers(non-smoker, $1873{\mu}mol/L$ vs. smoker, $1754{\mu}mol/L$, p=0.006). Conclusions: These results suggest that inflammation and oxidative stress are related to airflow limitation severity in retired miners with COPD, and there was a correlation between inflammation and oxidative stress.

Objectives : The purpose of this study is to investigate the anti-oxidative and the anti-inflammatory effects of Danpitang(DPT) extract in RAW 264.7 macrophages. Methods : The macrophage cell line RAW 264.7 cells were used and MTT assay was performed to measure the cell viabilities at the various concentrations of DPT($50-400{\mu}g/m{\ell}$). Nitric oxide(NO) was measured in LPS-induced RAW 264.7 cells. Expressions of iNOS, COX-2, $TNF-{\alpha}$, $IL-1{\alpha}$, $IL-1{\beta}$ and IL-6 were also performed by real-time PCR. Protein expression of iNOS and COX-2 was confirmed by western blot. The anti-oxidant activities of DPT was measured by DPPH radical scavenging activity. Results : 1. There was no cytotoxicity in RAW 264.7 cells treated with DPT compared to the control. 2. DPT treated group significantly inhibited NO production compared to the LPS treated group. 3. DPT treated group significantly decreased mRNA expressions of iNOS, COX-2, $TNF-{\alpha}$, $IL-1{\alpha}$, $IL-1{\beta}$ and IL-6 compared to the LPS treated group. 4. To evaluate the safety of the products for the human body, Adverse events, SCORAD Index Assessment were conducted; There were no severe adverse events during this study. And SCORAD Index showed a statistically significant decrease in treatment group in baseline, 2 weeks and 4 weeks. Therefore, it is suggested that products, if used for certain period, should be safe for the human body. 5. DPT was found to have high DPPH free radical scavenging ability. Conclusions : According to the above results, DPT can be used as a therapy in various anti-inflammatory skin diseases.

This study investigated the 𝛽-glucosidase activity of lactic acid bacteria and specifically eleutheroside E and B from Acanthopanax senticosus after bioconverting them into syringaresinol (SYR). Out of 125 lactic acid bacteria strains isolated from kimchi and other sources, 46 exhibiting both extracellular and internal 𝛽-glucosidase activity were identified. Notably, strains LFFR 20-011 (Lactobacillus curvatus) and LFFR 20-043/LFR20-050 (Levilactobacillus brevis) enhanced SYR production by more than two-fold during Acanthopanax senticosus fermentation. Further investigation revealed that SYR significantly promoted osteoblast differentiation, as evidenced by the increased mRNA expression levels of early and mature osteoblast markers, including Runx2, type I collagen, and osteocalcin. These findings suggested that the enhanced presence of SYR through bioconversion by Acanthopanax senticosus may improve bone health. These results provide foundational data supporting the development of lactic-acid-bacteria-fermented Acanthopanax senticosus as a functional food aimed at promoting skeletal health in older adults.

This study was conducted to examine effects of brewery meal-based fermented feedstuff supplemented with Aspergillus oryzae(AO) or Saccharomyces cerevisiae(SC) on luminal micro-organism of Korean native cattle. Two cows equipped with luminal cannulas were used as experimental animals. Experiment was done with three treatment groups: $71.5\%$ of commercial feed and $28.5\%$ of com silage(control): $45.0\%$ of commercial feed, $26.5\%$ of fermented feedstuff supplemented with AO and $28.5\%$ of corn silage(TAO): $45.0\%$ of commercial feed, $26.5\%$ of fermented ffedstuff supplemented with SC and $28.5\%$ of corn silage(TSC). The number of total viable bacteria (p<0.05), anaerobic fungi and protozoa(p<0.05) was higher in TAO and TSC than in control. The number of proteolytic bacteria(p<0.05), cellulolytic bacteria and xylan fermenters tended to be higher in TAO and TSC than in control. The dry matter recovery (DMR) of protozoa was higher in TAO and TSC than in control(p<0.05). The crude protein (CP) content of total microbes and protozoa was higher in TSC than in control and TAO (p<0.05). The CP content of bacteria was higher in TAO and TSC than in control(p<0.05). The ether extract(EE) content of the total microbes was higher in TAO than in control and TSC(p<0.05), and the EE of protozoa and bacteria were higher in TSC than in control and TAO(p<0.05). The ratio of essential amino acids of total microbe was higher in control than in TAO and TSC(p<0.05). The ratio of methionine and alanine of bacteria was higher in TAO and TSC than in control(p<0.05). The results suggested that the feeding of fermented feedstuff supplemented with AO or SC had an influence on the numbers of ruminal microorganism and the changes of microbial body composition.

This study was conducted to compare and evaluate fermentable and nutritional characteristics of brewery meal-based fermented feedstuffs supplemented with Aspergillus oryzae (AO) and Saccharomyces cerevisiae (SC). Experiments were divided into three treatment groups; fermented feedstuff supplemented with $1\%$ of AO(FFAO), fermented feedstuff supplemented with $1\%$ of SC(FFSC), and fermented feedstuff supplemented with $0.5\%$ of AO and $0.5\%$ of SC(FFAS). For changes of crude protein contents by 48 h fermentation, there were no significant differences among treatments. Ether extract(EE) contents were significantly increased by 48 h fermentation (p<0.05). Neutral detergent fiber(NDF) contents of FFAO, FFSC and FFAS were significantly decreased by 48 h fermentation(p<0.05), but acid detergent fiber(ADF) and acid detergent lignin (ADL) contents were not different. The pH of FFAO and FFAS was decreased more rapidly than that of FFSC(p<0.05), reaching a plateau after 24 h. Alcohol content was increased rapidly until 18 h in FFAO and was increased rapidly until 12 h in FFSC and FFAS, and alcohol content of FFAO, FFSC and FFAS was maintained constantly after 24 h. The ammonia N content of FFAO, FFSC and FFAS was 0.022, 0.073 and $0.040\%$ at 48 h, respectively, and then ammonia N was over twice higher in FFSC than in FFAO and FFAS(p<0.05). Dextrose content was increased until 6 h in FFAO but was rapidly decreased in FFSC and FFAS until 6 h(p<0.05). Lactate content was higher in FFAO and FFAS than in FFSC(p<0.05). Consequently, when we added AO in formulation of fermented feedstuff with brewery meal which moisture content was high, EE, alcohol, and lactate contents were increased, but NDF and ammonia N contents were reduced. Therefore, it is expected that AO will be effective to increase the feed value and the preservation of fermented feedstuff with a high moisture content.

A metabolism trial with four ruminally fistulated sheep was conducted in a $4{\times}4$ Latin square design to examine the effect of concentrate to roughage ratio (70:30 vs. 85:15) and oil source (soybean oil vs. rapeseed oil) on the ruminal fermentation pattern and $C_{18}$-fatty acids composition including trans11-$C_{18:1}$ (trans11-ODA) and cis9, trans11-18:2 (cis9, trans11-CLA) in the rumen fluid and plasma. Oil was added to the concentrate at 5% level of the total diet (DM basis) and chopped rye grass hay was fed as roughage. An increased level of concentrate (85%) within supplemented oil slightly lowered pH but increased ammonia concentration. Supplementation of rapeseed oil relatively increased pH and ammonia concentration. Higher concentrate level resulted in increased tendencies of total VFA concentration while oil source did not affect the total VFA concentration and VFA proportion. Whole tract digestibilities of DM, CP, EE, NDF and OM in diets slightly increased at higher concentrate level. Proportions of oleic acid ($C_{18:1}$) and linoleic acid ($C_{18:2}$) in the rumen fluid were influenced by the fatty acid composition of oil source but oil source did not affect the in vitro formations of trans11-ODA and cis9, trans11-CLA. Slightly increased trans11-ODA and cis9, trans11-CLA proportions, however, were observed from the sheep fed high roughage diet supplemented with both soybean oil and rapeseed oil. The $C_{18:1}$ and $C_{18:2}$ composition in supplemented oils responded to those in plasma of sheep. Effects of concentrate to roughage ratio and oil source on trans11-ODA and cis9, trans11-CLA proportions in plasma were found to be small. Proportion of cis9, trans11-CLA in plasma tended to be increased from the sheep fed high roughage diet and collection time at 9h post feeding.

Aerosol Deposition (AD) is anovel way to fabricate bioactive ceramic coatings in biomedical implants and prostheses applications. In the present work, silicon-substituted hydroxyapatite (HA) coatings on commercially pure titanium were prepared by aerosol deposition using Si-HA powders. The incorporation of silicon in the HA lattice is known to improve the bioactivity of the HA, makingsilicon-substitute HA an attractive alternative to pure HA in biomedical applications. Si-HA powders with the chemical formula $Ca_{10}(PO_4)_6-x(SiO_4)x(OH)_2-x$, having silicon contents up to x=0.5 (1.4 wt%), were synthesized by solid-state reaction of $Ca_2P_2O_7$, $CaCO_3$, and $SiO_2$. The Si-HA powders were characterized by X-ray diffraction (XRD), X-ray fluorescence spectrometry (XRF), and Fourier transform infrared spectroscopy(FT-IR). The corresponding coatings were also analyzed by XRD, scanning electron microscopy (SEM), and electron probe microanalyzer (EPMA). The results revealed that a single-phase Si-HA was obtained without any secondary phases such as $\alpha$- or $\beta$-tricalcium phosphate (TCP) for both the powders and the coatings.The Si-HA coating was about $5\;{\mu}m$ thick, had a densemicrostructure with no cracks or pores. In addition, the proliferation and alkaline phosphatase (ALP) activity of MC3T3-E1 preosteoblast cells grown on the Si-HA coatings were significantly higher than those on the bare Ti and pure HA coating. These results revealed the stimulatory effects induced by siliconsubstitution on the cellular response to the HA coating.
