Objective : This study was performed to investigate the effect of blood-letting cupping treatment for acute ankle sprain because there are few studies with evidence-based approach. Method : Twenty-nine patients, who had no fracture and had injured by external force and had less than 1 week passed since onset and had not been treated, were randomly divided into control or treatment group by tossing a coin. The treatment group received blood-letting cupping. After 3rd treatment, the outcomes were assessed using Ankle-Hindfoot Scale (AHS) and Numeric Rating Scale (NRS). Result : Nineteen out of 29 patients were finally assessed. The treatment group (n=11) was significantly different from the control group (n=8) in AHS and NRS (p=0.041, 0.026, respectively). Conclusion : The blood-letting cupping has an objective effect on reduing pain for acute ankle sprain.

Objectives : The aim of this study is to report a case of a 51-year-old patient with Herpes zoster, whose symptoms were relieved within five weeks after the East-west medical combined treatment. Methods : A Herpes zoster patient with extreme pain around the right lower ribs and lower back was admitted into the Korean medicine hospital. Bee venom acupuncture was applied directly onto the site of pain and electroacupuncture was applied on $GV_6-BL_{20}$, inferior site of spinous process of the 12th thoracic vertebra-$BL_{21}$, $GV_5-BL_{22}$, $GV_4-BL_{23}$ six times a week. Moxibustion was applied on $BL_{49}$, $BL_{50}$, $BL_{51}$, $BL_{52}$, $GB_{25}$, $LR_{13}$ six times a week, and the patient took daily doses of herbal medicine and western medicines such as anticonvulsants, analgesics, antiepileptics. The patient's symptoms were evaluated with numeric rating scale(NRS) and neuropathic pain scale(NPS). Results : The results were as follows: 1. After the East-west medical combined treatment, the NRS grade decreased from 8 to 1. 2. On the neuropathic pain scale, the patient's symptoms changed from deep sharp pain and burning sensation to superficial dull pain and coldness. Sensitivity to touch, discomfort, and itchiness also decreased. Sudden attacks of pain appeared 14 to 21 days after onset, but disappeared after final treatment. Conclusions : The results of the above patient suggests that the East-west medical combined treatment may be effective for total remission of herpes zoster. Further research is needed to confirm such effects.

In membrane covered stent, occlusion and fracture from membrane degradation by gastric acid sometimes occurred. Therefore, we investigated the physical properties of membrane covered stent according to its ingredient and concentration in gastric acid environment. Membrane covered stents consisted of silicone and polyurethane with 15%, 18%, 20% concentrations were used. After incubating stents in a condition of pH 1.2, we checked any changes at every 3 weeks for 18 weeks. The changes of membrane surface, radial expansion and recovery force of stent were investigated. Coating thickness increased proportionally to an increase in ingredient concentration. Surface was evenly coated with silicone compared to the case with polyurethane and its homogeneity was excellent in a high concentration. Degradation was much severe in the case of polyurethane. The radial force of silicone was higher than polyurethane, and the decrease of radial and recovery force was higher in the case of polyurethane. In conclusion, high concentration of silicone membrane was more stable than polyurethane in acid environment of in vitro study.

This study relates to an investigation into semi-dry manufacturing process of BP sludge based on non-heating production method. In this study, we conducted a research into reduction of water content ratio which arose from mixture of BP by-products of high water content ratio(50% or higher) with industrial by-products to use such BP by-products as construction materials in large quantity. We measured the reduction rate of water content ratio at the feeding ratio of water content reduction agent(1:0.5) in BP by-products. The results showed that water content ratio was the lowest with 18.5% in the mixture of PA+CFA(1:0.5). Moreover, water content ratio ranged between approximately 9.2% and 11.4% at the age of 1 day to 2 days at the aging temperature of $20-30^{\circ}C$, suggesting that the water content ratio was in the range within 10% which was a level suitable for use as construction material in this study. Meanwhile, we compared and evaluated the physical properties of non-heated BP by-products based on post-aging pulverization method. The results showed that there was no significant difference, depending on pulverization method. When production efficiency and economic feasibility were taken into consideration, it was found desirable to use fine particle pulverizer or pin mill enabling continuous production.

To provide a basis for studying the pharmacological actions of tetracaine HCl, we analyzed the membrane activities of this local anesthetic. The n-(9-anthroyloxy) stearic and palmitic acid (n-AS) probes (n = 2, 6, 9, 12 and 16) have been used previously to examine fluorescence polarization gradients. These probes can report the environment at a graded series of depths from the surface to the center of the membrane bilayer structure. In a dosedependent manner, tetracaine HCl decreased the anisotropies of 6-AS, 9-AS, 12-AS and 16-AP in the hydrocarbon interior of synaptosomal plasma membrane vesicles isolated from bovine cerebral cortex (SPMV), and liposomes derived from total lipids (SPMVTL) and phospholipids (SPMVPL) extracted from the SPMV. However, this compound increased the anisotropy of 2-AS at the membrane interface. The magnitude of the membrane rotational mobility reflects the carbon atom numbers of the phospholipids comprising SPMV, SPMVTL and SPMVPL and was in the order of the 16, 12, 9, 6, and 2 positions of the aliphatic chains. The sensitivity of the effects of tetracaine HCl on the rotational mobility of the hydrocarbon interior or surface region was dependent on the carbon atom numbers in the descending order 16-AP, 12-AS, 9-AS, 6-AS and 2-AS and on whether neuronal or model membranes were involved in the descending order SPMV, SPMVPL and SPMVTL.

Objectives : It is well known that Sibjotang (Shizaotang), traditional herbal medicine formula, regulates the body fluid blood pressure homeostasis. This study is to investigate whether Sibjotang improves diabetic renal dysfunction in type II diabetes mellitus animal model, db/db mice. Methods : The animals model were divided into three groups at the age of 8 weeks; control group (C57BLKS/J-db/m mice), diabetic group [(C57BLKS/J+Lepr)-db/db mice], and Sibjotang group [(C57BLKS/J+Lepr)-db/db mice + Sibjotang 100 mg/kg/day]. During 8 weeks of treatment, blood glucose and urinary albumin excretion were checked in metabolic chamber at 8, 12, and 16 weeks of age, respectively. Results : Body weight and food intake of diabetic group were significantly higher than control group after 8 weeks administration. However, there were not significant different between the diabetic group and Sibjotang group. Urinary albumin excretion was significantly decreased in the Sibjotang group than the diabetic group. In addition, supplementation with Sibjotang significantly lowered levels of blood glucose, insulin, and homeostatic model assessment-insulin resistance (HOMA-IR), suggesting reduced insulin resistance. The ratio of mesangial matrix/glomerular area was markedly larger in diabetic group than control group, whereas Sibjotang significantly reduced this expansion. Moreover, immunohistological study revealed that Sibjotang attenuated the increase of transforming growth $factor(TGF)-{\beta}$ expression in kidney. Conclusion : Sibjotang ameliorates diabetes-associated renal injury through the improvement of the blood glucose and insulin sensitivity, and inhibiting the $TGF-{\beta}1$ expression. Therefore, Sibjotang may be a new therapeutic formula for the treatment of diabetic-associated renal dysfunction.

Purpose: At present, information regarding periodontal disease in geriatric patients is scarce. The purpose of this study was to quantify the periodontal pathogens present in the saliva of Korean geriatric patients and assess the relationship between the bacterial levels and the periodontal condition. Methods: Six putative periodontal pathogens were quantified by using a real-time polymerase chain reaction assay in geriatric patient groups (>60 years) with mild chronic periodontitis (MCP), moderate chronic periodontitis (MoCP), and severe chronic periodontitis (SCP). The copy numbers of Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, and Prevotella intermedia were measured. Results: It was found that the bacterial copy numbers increased as the severity of the disease increased from MCP to SCP, except for P. intermedia. For P. intermedia, it was found that samples in the MCP group yielded the largest amount. It was also found that the quantities of P. gingivalis, T. forsythia, and T. denticola, the so-called "red complex" bacteria, were lower than those of F. nucleatum, A. actinomycetemcomitans, and P. intermedia in all of the samples. Conclusions: Collectively, the results of this study suggest that the levels of P. gingivalis, T. forsythia, F. nucleatum, and T. denticola present in saliva are associated with the severity of periodontal disease in geriatric patients.

Vegetables contain high levels of nitrate, which can be converted to nitrite for reaction with secondary amines to form nitrosamines. In this study, we evaluated safety effects against nitrite and nitrosamine as well as anti-mutagenic activities of vegetable juices. To do this, the contents of nitrate, nitrite, and nitrosamines were determined in vegetable juices. The safety effects against nitrite and nitrosamine formation were also investigated under simulated human gastric conditions. The contents of nitrate and nitrite in common and organic kale and Angelica keiskei juices were 931~2,052 mg/kg and 13~82 mg/kg, respectively. However, seven kinds of nitrosamines were not detected in the vegetables juices. The nitrate content decreased when vegetable juices were digested under simulated human gastric conditions. Nitrosamine (N-nitrosodimethylamine) formation under simulated human gastric conditions was inhibited by addition of vegetable juices. In addition, vegetable juices, especially organically cultivated juices, showed anti-mutagenic effects in a Salmonella assay system. These results suggest that organically cultivated vegetable juices are a promising health-promoting source.

This study investigate the effects of extracts of five species of Korean native forest plants on lipid accumulation and reactive oxygen species (ROS) production during the differentiation of 3T3-L1 cells. Our results show that Korean native forest plants extracts significantly reduced lipid accumulation and ROS production during adipogenesis in 3T3-L1 cells. Especially, Rubus coreanus Miq. was most effective in the inhibition of lipid accumulation and ROS production at a concentration of $100{\mu}g/mL$. Moreover, Rubus coreanus Miq. extracts significantly inhibited adipocyte differentiation, which is dependent on down-regulation of peroxisome proliferator-activated receptor gamma, CCAAT/enhancer-binding protein alpha, and adipocyte-specific fatty acid binding protein, a key adipogenic transcription factor. Therefore, these results suggest that Rubus coreanus Miq. might be a valuable source of bioactive compounds with anti-adipogenic activity.

Despite the enforcement of minimum legal drinking age of 18 years of age since 1997, alcohol experimentation among Korean youth is believed to be greater than ever before. The use of alcohol jeopardizes physical, mental, and social development during a person's formative years, thereby endangering successful transitions from adolescent to adulthood. Even infrequent use of alcohol may result in intoxication and acute consequences, especially among youth, who may have low tolerance due to their smaller body size and may lack experience with the effects of alcohol. Using self-report questionnaire data collected from 1,697 highschool students nation-wide, the drinking behavior among Korean high school students and the relation between adolescents' alcohol expectancy and adolescent alcohol use patterns were examined. Results indicated that gender and the type of school(academic or vocational) were significant effects on the drinking behavior(drinking frequency, experience of drunkenness, the amount of alcohol consumed, experience of binge drinking and that of problems due to drinking). Male students than female students, and students of vocational schools rather than those of academic high schools reported more alcohol experimentation. Also, positive alcohol expectancy proved to have a significant relation with alcohol use among high-school students. That is, students who reported to think alcohol would have a positive effect on socializing, aggressiveness, relaxation of tensions, and enforcing sexual ability tended to drink more, to experience more binge drinking and more drinking problems. Variables of gender and the type of school also were found to have significant effects on alcohol expectancy. Males and students of vocational school held ideas of positive outcomes on drinking than others. Implications for further study on developing prevention programs are presented.
