This study examined the satisfaction of the married women from aged 20s through 50s with well-being oriented foods, considering the importance of each subordinate field and verifying the differences between the groups according to socio-demographic factors, purchase behavior factors, and well-being oriented dietary life factors, followed by an analysis of the relative influence of those relevant factors. A preliminary survey was conducted from January 4th-11th, 2009 to check if there were any problems or misunderstood parts before the main survey. After the preliminary study was conducted, certain problems were adjusted and supplemented, and then the main survey was conducted for twenty-three days, from January 4th to February 5th, 2009. The summaries of this study are as follows: First, in the view of the purchase behavior, the mainly purchased well-being oriented foods were farm products, and the leading purpose of the purchase was for the parents and the children. It was shown that 30% or more of the information sources on well-being oriented foods were families, relatives and neighbors. More than 66% of the purchasing was done at wholesale marts and the topped purchasing frequency was from 5 to 6 per month. More than 71% of payments for well-being oriented foods were \50,000~100,000 per month. More than 51% of the respondents answered that the proper price of well-being oriented foods was 1.2 times to 1.5 times of that of other foods. Second, the satisfaction of the well-being oriented foods was ranked as 3.21 to 3.28 out of 5, and varied with the usages and the methods of weights. Investigating the satisfaction with each subordinate field, the satisfaction with price was shown to be low. The satisfaction with the assortments of foods and the satisfaction with the therapeutic degree by thorough investigation and management of foods were also relatively low. Third, well-being oriented dietary behavior was shown to be characterized by two factors, through factor analysis in this study. One was an eco-friendly oriented behavioral factor and the other was a health oriented selective factor. Fourth, the stepwise multiple regression analysis results investigating the relative influence of the factors effecting satisfaction with well-being oriented foods showed that the top ranked factor affecting total satisfaction was eco-friendly oriented behavioral factor, followed by education level and purchasing sites, especially of consumer groups.

Objectives: Maekmoondong-tang and Jeongcheonhwadamgangki-tang are herbal decoctions which have been used as traditional therapeutic agents for asthma. This study was performed to investigate the effects of Maekmoondong-tang and Jeongcheonhwadamgangki-tang on immune Cell & serum OA-specific 19B in broncho-alveolar lavage fluid (BALF) in rat asthma model. Methods: Rats were sensitized with ovalbumin (OA); at day I the sensitized group and Maekmoondong-tang and Jeongcheonhwadamgangki-tang groups were systemically immunized by subcutaneous injection of 1mg OA and 300mg of $Al(OH)_3$ in a total volume of 2ml. At the same time, 1ml of 0.9% saline containing $6{\times}10^9$ B. pertussis bacilli was injected by i.p. for 14 days. After systemic immunization, the rats received local immunization by inhaling 0.9% saline aerosol containing 2% (wt/vol) OA. A day after local immunization, BAL fluid was collected from the rats. A day after local immunization, rats were orally administered with each of Maekmoondong-tang and Jeongcheonhwadamgangki-tang extract for 14 days. Lymphocyte, CD4+T-cell CD8+ T-cell counts, CD4+/CD8+ ratio in BALF, change of serum OA-specific IgE level, and CD4+T-cell CD8+T-cell percentage in the peripheral blood were measured and evaluated. Results: Maekmoondong-tang and Jeongcheonhwadamgangki-tang showed a suppressive effect on the rat asthma model. Maekmoondong-tang decreased total cell, lymphocyte, CD4+T-cell, CD8+T-cell in BALF, and serum OA specific 19B level as compared with the control group, whereas Maekmoondong-tang decreased CD4+/CD8+ ratio in BALF with statistical nonsignificance as compared with the control group. 1 decreased total cell, CD4+T-cell, CD4+/CD8+ ratio in BALF, and serum OA specific IgE level, whereas Jeongcheonhwadamgangki-tang decreased ymphocyte, and CD8+T-cell in BALF with statistical nonsignificance as compared with the control group. CD4+T-cell and CD8+ T-cell percentage in peripheral blood were not changed significantly in all the experimental groups. Conclusions: This study shows that Maekmoondong-tang and Jeongcheonhwadamgangki-tang have a suppressive effect on asthma. Maekmooruiong-tang and Jeongcheonhwadamgangki-tang would be useful asthma treatment agents.

The objective of the present study was to evaluate the protective effect of red ginseng (RG) according to steaming time on 150 mM HCl/60 % ethanol induced gastric ulcer models in mice. The sample was divided into 3 groups-G (dried ginseng), RG 4 (steamed 4 h and dried ginseng), RG 6 (steamed 6 h and dried ginseng), and determined through in vitro experiments, such as 1,1-diphenyl-2-picrylhydrazyl and 2,2'-azinobis-3-ethyl-benzothiazoline-6-sulfonic acid radical scavenging activity, HPLC analysis, total polyphenol, and flavonoid contents. In vitro experiment results were depended on steaming hours. Based on the results, we chose two samples (G, RG 6) and conducted in vivo experiments. Mice were divided into 5 groups: Nor (normal group), Con (acute gastritis mice treated with distilled water), G (gastris induced by HCl/Ethanol treated with 100 mg/kg G), RG 6 (gastris induced by HCl/ethanol treated with 100 mg/kg RG 6), and SC (gastris induced by HCl/Ethanol treated with 10 mg/kg sucralfate). In our results revealed that RG 6 suppressed elevated reactive oxygen species, and inflammatory related makers, such as cyclooxygenase-2, inducible nitric oxide synthase, tumor necrosis factor alpha, and interleukin-1 beta. In addition, gastric lesion area was improved. These results suggest that RG 6 protects the stomach by attenuating oxidative stress and inflammatory response under gastric ulcer conditions. Therefore, RG 6 should be a potential therapeutic agent for the treatment of acute gastric ulcer.

Background: Ventilator-associated pneumonia caused by multi-drug resistant Acinetobacter baumannii has been increasing and growing as a threat in intensive care units. Limited therapeutic options have forced clinicians to choose colistin with or without combination of other antibiotics. We tried to compare the effectiveness between colistin monotherapy and combination therapy based on in vitro synergistic tests. Methods: From January 2006 to December 2007 in medical ICU of a tertiary care hospital in Korea, We reviewed the medical records of patients treated with intravenous colistin due to ventilator-associated pneumonia caused by multi-drug resistant Acinetobacter baumannii. Results: A total of 41 patients were analyzed. 22 patients had been treated with colistin monotherapy and 19 patients with colistin and combination antibiotics that were found to have in vitro synergistic effects. Baseline characteristics were similar in both groups but the mean duration of colistin administration was significantly longer in the combination group (19.1${\pm}$11.2 days vs. 12.3${\pm}$6.8 days, p=0.042). There were no significant differences in outcome variables between the two groups. Conclusion: Combination treatment based on the in vitro antimicrobial synergy test did not show better outcomes compared with colistin monotherapy in VAP caused by multi-drug resistant A. baumannii.

Sudden idiopathic sensorineural hearing loss is a disease that develops within several hours to several days. Its etiology has not yet been verified, but the disturbance of the circulation of blood in the inner ear, inner-ear hydrops, and viral infection are considered possible causes of the disease. This study was conducted to evaluate the effect of Panax ginseng extract, which is known to have a vasodilatory effect, on sudden sensorineural hearing loss. Sixty-nine patients suffering from sudden sensorineural hearing loss were admitted to Korea University Anam Hospital from March to December 2008. They were divided into the experimental (30 ears) and control (39 ears) groups. Ginseng extract (2700 mg/day, 4 weeks) was added to the therapeutic regimen in the experimental group. The effect of ginseng extract therapy was analyzed according to the factors relating to the prognosis. A considerable hearing improvement was documented in both groups (32.2 dB in the experimental group and 25.8 dB in the control group). However, there was little beneficial effect of ginseng extract on additional hearing improvement compared with control. The total recovery rate of the experimental group (80.0%) was better than that of the control group (58.9%), and the experimental group's high-tone hearing gain at 3 kHz (29.7 dB) was better than that of the control group (21.7 dB). The results of the study suggest that the effects of ginseng therapy tend to be superior to those of the conventional therapy, but the difference between the two is not statistically significant. The hearing gains tend to be in the higher frequencies and may be due to the promotion of cellular differentiation from the supporting cells.

Objective: This study was perfomled to examine the therapeutic effect of aqua-acupuncture solution of Hominis Placenta(HP) on kidney and liver intoxicated by $HgCI_2$ in rats. Methods: $10\%$ and $25\%$ HP aqua-acupuncture were carried out everyday for 8 days on corresponding bilateral loci of Shinsu(BL23) and Kansu(BL18), respectively, after mercuric chloride intoxication in rats. Thereafter BUN, creatinine, GOT, GPT, ALP, ${\gamma}$-GT, albumin and total bilirubin were measured before intoxication, and at the 4th and the 8th experimental day. Histopathological and immunochemical observation were also carried out. Results: 1. It showed significant decreases of BUN in the group of $10\%$ HP aqua-acupuncture into Shinsu on the 4th experimental day as compared with the control group. 2. It showed significant decreases of creatinine in the group of $10\%$ HP aqua-acupuncture into Shinsu on the 4th and the 8th experimental days as compared with the control group. 3. There were not any significant changes of GOT, GPT, ALP,${\gamma}$-GT, albumin and total bilirubin in the HP aqua-acupuncture groups compared with the control group. 4. By the histopathological observations on kidney under a light microscope, alt the $10\%$ and $25\%$ HP aqua-acupuncture into Shinsu showed the preventive effect on tubulo-interstitial necrosis and muItifocal calcification in tubular lumen respectively compared with the control group. 5. By the histopathological observations on liver under a light mIcroscope, the groups $10\%$ and $25\%$ HP aqua--acupuncture into Kansu did not show any significant changes in the liver compared with the control group. 6. By the immunochemical analysis of heat shock protein(hsp) and glucose-regulated protein(grp) in rat renal cortex, the expressions of hsp70 and grp78 were decreased in the $10\%$ and $25\%$ HP aqua-acupuncture into Shinsu respectively compared with the control group. Conclusion: These results suggest that Hominis Placenta aqua-acupuncture have an effect on prevention and protection of renal intoxication by $HgCI_2$ in rats.

Background: Oxidation plays an important role in acute lung injury. This study was conducted in order to elucidate the effect of repetitive post-treatment of N-acetylcysteine (NAC) in lipopolysaccaride (LPS)-induced acute lung injury (ALI) of rats. Methods: Six-week-old male Sprague-Dawley rats were divided into 4 groups. LPS (Escherichia coli 5 mg/kg) was administered intravenously via the tail vein. NAC (20 mg/kg) was injected intraperitoneally 3, 6, and 12 hours after LPS injection. Broncho-alveolar lavage fluid (BALF) and lung tissues were obtained to evaluate the ALI at 24 hours after LPS injection. The concentration of tumor necrosis factor ${\alpha}$ (TNF-${\alpha}$) and interleukin $1{\beta}$ (IL-$1{\beta}$) were measured in BALF. Nuclear factor ${\kappa}B$ (NF-${\kappa}B$), lipid peroxidation (LPO), and myeloperoxidase (MPO) were measured using lung tissues. Micro-computed tomography (micro-CT) images were examined in each group at 72 hours apart from the main experiments in order to observe the delayed effects of NAC. Results: TNF-${\alpha}$ and IL-$1{\beta}$ concentration in BALF were not different between LPS and NAC treatment groups. The concentration of LPO in NAC treatment group was significantly lower than that of LPS group ($5.5{\pm}2.8$ nmol/mL vs. $16.5{\pm}1.6$ nmol/mL) (p=0.001). The activity of MPO in NAC treatment group was significantly lower than that of LPS group ($6.4{\pm}1.8$ unit/g vs. $11.2{\pm}6.3$ unit/g, tissue) (p<0.048). The concentration of NF-${\kappa}B$ in NAC treatment group was significantly lower than that of LPS group ($0.3{\pm}0.1\;ng/{\mu}L$ vs. $0.4{\pm}0.2\;ng/{\mu}L$) (p=0.0001). Micro-CT showed less extent of lung injury in NAC treatment than LPS group. Conclusion: After induction of ALI with lipopolysaccharide, the therapeutic administration of NAC partially attenuated the extent of ALI through the inhibition of NF-${\kappa}B$ activation.

In this study we investigated the effect of medical history on the incidence of stroke in Korean population. 217 stroke patients were enrolled as a case group. 160 non-stroke patients and 146 normal and non-stroke patients were enrolled as a control and a normal group, respectively, from Jul. 2005 to Mar. 2007. Stroke patients were hospitalized within 2 weeks after the onset of stroke. Medical history was gathered by interviewing each patient. Clinical data were analyzed using SAS software (ver 9.1). Hypertension and diabetes mellitus (DM) were statistically significant in a case group when compared with control and normal groups. Other parameters, such as transient ischemic attack, hyperlipidemia, ischemic heart disease, facial palsy, migraine, and hypochondria, did not show any statistical significance. The same association pattern was observed in the ischemic stroke patients of case group. On the other hand, hemorrhagic stroke patients of case group showed a significant difference in DM when compared with other subject groups. More efficient therapeutic strategy should be considered for patients with medical history, especially hypertensin and DM, to reduce the stroke incidence in Korean population.

Background: Lipo-prostaglandin E1 (Lipo-$PGE_1$) has vasodilating and platelet aggregation inhibitory characteristics and it has been used as a treatment for patients with blood flow dysfunction disease. Based on the mechanisms of lumbar spinal stenosis, including veno congestion, neuro-ischemia and mechanical compression, we aimed to study whether intravenous Lipo-$PGE_1$ injection has any therapeutic effect on hyperalgesia in a rat foraminal stenosis model. Methods: In this study, twenty male Sprague-Dawley rats were divided into the control (n = 10) and Lipo-$PGE_1$ (n = 10) groups. A small stainless steel rod was inserted into the L5-6 intervertebral foramen to induce intervertebral foramen stenosis and chronic DRG compression. In the Lipo-$PGE_1$ group, $0.15{\mu}g/kg$ of Lipo-$PGE_1$ were injected intravenously via a tail vein for 10 days starting from the $3^{rd}$ day after operation. Behavioral testing for mechanical and thermal hyperalgesia was performed for 3 weeks after the injections. Results: From the $10^{th}$ day after Lipo-$PGE_1$ injection, the rats in the experimental group showed significant recovery of their mechanical threshold, and this effect was maintained for 3 weeks. No significant differences of the thermal hyperalgesia were observed between the two groups. Conclusions: These findings suggest that intravenously injected Lipo-$PGE_1$ may be effective for alleviating neuropathic pain, which isthe main symptom of spinal stenosis, by improving the blood flow dysfunction.
