Obesity is a risk factor for numerous health problems. Behavior therapy is important for obesity treatment. The aim of the present study was to identify the parameters that are associated with successful weight reduction. A database of 123 subjects who underwent weight reduction programs at the Center for Health Promotion, Samsung Medical Center from June 2001 through November 2004 was retrospectively analyzed. The goal of the program was to reduce the body weight by more than 5% during the follow-up period. The study population was divided into 2 categories (the success group and the failure group) based on the outcome of weight reduction. We analyzed the demographic, laboratory and clinical parameters to determine the predictors of successful weight reduction. The prevalence of success group was 36.6% (45/123). Significant correlations for successful weight reduction were found for the follow up period and the frequency of medical visits. Our results suggest that strong motivation was the most important factor for successful weight reduction.

Many risk factors for atherosclerosis have been proposed to identify high risk individuals. We conducted a retrospective study to determine the risk factors for development of carotid stenosis (CS) in Koreans. Database of 2,805 subjects who underwent a check up of carotid artery for health examination were analyzed. Stenosis (%) of common carotid artery or proximal internal carotid artery was examined with ultrasonography. Subjects were divided into 2 groups (Group I; CS <10%, Group II; CS > or =30%). We compared demographic, laboratory and clinical data between 2 groups to determine the risk factors of CS. One hundred ninety seven subjects (7.0%) were categorized as Group II. At age- and sex-adjusted multivariate analysis, diabetes mellitus, hypertension, cerebrovascular disease, ischemic heart disease, hyperlipidemia, aspirin medication, current smoking, fasting glucose, total cholesterol, low density lipoprotein-cholesterol (LDL-C) and leukocyte count were significant risk factors of CS. At stepwise logistic regression analysis, age, hypertension, hyperlipidemia, LDL-C and leukocyte count were independent risk factors. At subgroup analysis by smoking, age and leukocyte count were independent risk factors in smoker and age and hypertension in nonsmoker.

OBJECTIVES: This study was conducted to investigate the systematic error, such as seasonal change or inadequate food items, in a food frequency questionnaire administered to workers in a Nuclear Power Plant, Korea. METHODS: We performed three repeat-tests with 28 subjects on May 13, July 8 and Dec 16, 1992. Our food frequency questionnaire (FFQ) comprised 84 foods organized into 7 food-groups, and was composed of the items of usual intake frequency (8 categories) and the amount per intake (3 or 4 categories) over the previous year. We compared the means of intake frequency and the frequency of the portion-size according to each season using Repeated Measures ANOVA and Pearson's chisquare test with Fisher's exact test. RESULTS: We found the significant seasonal changes of several food items in intake frequency measurement. These items were typical seasonal foods such as mandarin orange, plum and green vegetables, while the single questions consisted of inadequate food items such as thick beef or similar soup and various kimchi products. Significant seasonal changes in portion-size were found in only two items: cooked rice-brown and fresh.frozen fishes. CONCLUSIONS: The systematic errors observed could caused loss of validity in the FFQ. Consideration should be given for seasonal variation in FFQ survey and methodological concerns are needed to improve the quality for measuring usual diet pattern.

Use of adenoviruses as vehicle for gene therapy requires that target cells express appropriate receptors such as coxsakievirus and adenovirus receptor (CAR). We show here that CAR-deficiency in cancer cells, that limits adenoviral gene delivery, can be overcome by using adenovirus complexed with the liposome, Ad-PEGPE [1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[methoxy(poly-ethylene glycol)-2000]. We first confirmed that CT-26 mouse colon cancer cells are deficient in CAR by RT-PCR, and then showed that CT-26 cells infected with Ad-GFP/PEGPE exhibited highly enhanced expression of green fluorescent protein (GFP), compared with those infected with Ad-GFP. GFP expression depends on the dose of liposome and adenovirus. Luciferase expression in livers treated with Ad-luc/PEGPE was about 1,000-fold less than those infected with Ad-luc. In a liver metastasis mouse tumor model developed by intrasplenic injection of CT-26 cells, luciferase expression following i.v. injection of Ad-luc/PEGPE was significantly higher in tumors than in adjacent non-neoplastic liver. Following systemic administration of Ad-GFP/PEGPE, GFP expression increased in tumors more than in adjacent liver while the reverse was true following administration of Ad-GFP. In the latter case, GFP expression was higher in liver than in tumors. This study demonstrates that systemic delivery of PEGPE-adenovirus complex is an effective tool of adenoviral delivery as it overcomes limitation due to CAR deficiency of target cells while reducing hepatic uptake and enhancing adenoviral gene expression in tumors.

A number of recombinant proteins isolated from cell sources are being produced for biopharmaceuticals. Although most biopharmaceuticals are highly purified, there is a safety concern that such recombinant products could be contaminated with impurities including adventitious virus, mycoplasma, endotoxin and oncogenic DNA. Residual DNA in recombinant biopharmaceuticals is a potential risk factor and must be evaluated and removed to meet the regulatory guidelines. Recombinant HPV type 16 L1 VLPs, recombinant protein produced in Spodoptera frugiperda (Sf) 9 insect cells, is a HPV subunit vaccine candidate which has been studied as a preventive vaccine of cervical cancers. In this study, we performed detection and quantification of residual cellular DNA in the production of recombinant HPV type 16 L1 VLPs. HPV-16 L1 VLPs were purified by processes including detergent lysis, sonication treatment, sucrose cushion centrifugation, CsCl equilibrium density centrifugation, and DNase treatment which was added to inactivate residual cellular DNA after CsCl centrifugation step. We have developed a precise assay based on a dot-blot hybridization using digoxigenin random primed labeling DNA probes for the detection and quantification of residual cellular DNA during the purification process and final products. Detection limit of residual cellular DNA was 0.1 ng in this assay and the amount of residual cellular DNA in the final product was 0.5 ng~1 ng per 100 microgram of protein. This study describes safer and more sensitive methods alternative to radioactive techniques employed for residual cellular DNA quantification of biopharmaceuticals produced by recombinant protein technology and presents method validation data demonstrating precision and reproducibility.

Ferric carboxymaltose is a non-dextran?iron complex used in patients with iron deficiency. However, iron injections may lead to long-lasting brown discoloration secondary to extravasation at the injection site. We herein report a case involving a patient who developed pigmentation after intravenous iron injection and was successfully treated with combined laser therapy. A 36-year-old woman presented with circumscript pigmentation on her left arm after having undergone intravenous iron injection for the treatment of iron deficiency anemia. Histopathologic examination revealed basal hypermelanosis and dermal infiltration of siderophages. Combined therapy with 1064 nm Nd:YAG laser and 595 nm pulsed dye laser was performed to treat the lesion, and marked improvement was noted after five sessions.

BACKGROUND AND OBJECTIVES: Drug-eluting stents (DES) have been shown to substantially reduce both angiographic and clinical restenosis. Cypher(R) (sirolimus-eluting stent, Cordis, Johnson and Johnson, Florida, USA) and Taxus(R) (paclitaxel-eluting stent, Boston Scientific, Boston, USA) are the two most widely used DESs, and they both have distinct pharmacological properties and release kinetics. It has been not studied whether these two DESs show different angiographic outcomes when they are simultaneously implanted in the same patient. SUBJECTS AND METHODS: We retrospectively analyzed the angiographic findings of the short-term follow-up in 34 patients (average age: 63 year old, 9 women) in whom both Cypher and Taxus stents were implanted at the same time for the treatment of obstructive coronary lesion. RESULTS: There was no significant difference in the basal angiographic characteristics of the lesions that had two stents deployed in terms of the AHA/ACC classification, reference diameter, the percent diameter stenosis and minimal luminal diameter. The post-procedure results were similar between the two stents. At 6 months follow-up, the Cypher stent displayed significantly less in-stent lumen loss compared with the Taxus stent (0.16+/-0.04 mm vs 0.27+/-0.04 mm; respectively, p=0.040) and a smaller percent diameter stenosis (15.9+/-1.3% vs 19.9+/-2.2%, respectively, p=0.049). CONCLUSION: The Cypher stent showed significantly less luminal loss during short term follow-up compared with the Taxus stent when implanted in the same patient. This result suggests that in a given individual patient, the Cypher stent induces less neointimal proliferation than does the Taxus stent.
