  • 4 kinds of Regional Special Natural Products (RSNPs), such as Anthrisci radix, Psoraleae semen, Siegesbeckiae herba and Corni fructus were examined to verify for anti-obesity effect. $PPAR\gamma$ (peroxisome proliferator-activated receptor $\gamma$) from 3T3-L1 cell concerning adipocyte differentiation was suppressed by different concentraton of 4 RSNPs with western blot, when treated RSNPs' extract and MDI (IBMX, Dexamethasone, Insulin) at the same time. Also, SREBP-1 (Sterol regulatory element binding protein) controlling lipogenesis and $PPAR\gamma$ expression levels were reduced by these 4 RSNPs' extract, when these chemicals after differentiation of 3T3-L1 cell. And lipid droplets were reduced by 7.5%, 14.4%, 18.3% and 30% at different concentration of Anthrisci radix from Oil Red O staining. Also, it was reduced by 2%, 4.9%, 9.3% and 38% at different concentration of Psoraleae semen. For Siegesbeckiae herba, it was inhibited by 1.4%, 6.4%, 16.4% and 30.1%, respectively. And Corni fructus was also showed by 0.9%, 6.3%, 13.7% and 33% at same concentration of Siegesbeckiae herba. These 4 kinds of RSNPs were expected for a useful material for anti-obesity materials.

  • Objectives : The aim of this study was to investigate the anti-obesity potential and mechanisms of action of Rhizoma Atractylodis(RA) herbal acupuncture in high fat diet- induced obese ICR mice. Methods : Sample solutions for herbal acupuncture were prepared from the Rhizoma Atractylodis water extract powder at concentration of 150mg/kg and 300mg/kg with distilled water. Five week-old ICR mice acclimatized to the laboratory environment for 1 week were allocated into four groups: regular diet group (RD), high fat diet group(HFD), groups fed HFD with 150mg/kg RA herbal acupuncture treatment (RAE 150) and with 300mg/kg RA herbal acupuncture treatment(RAE 300). Herbal acupuncture groups were injected with either 150mg/kg or 300mg/kg of Rhizoma Atractylodis(RA) subcutaneously onto both Sinsu($BL_{23}$) alternately on the same time everyday for 30days. Body weight, gross appearance of epididymal fat area, blood glucose, insulin, insulin resistance(HOMA-IR), non-esterified fatty acid, cholesterol, triglyceride, AST, ALT, histological analysis of white adipose tissue, gene expression responsible for adipocyte differentiation and AMPK activation were analyzed. Results : RA herbal acupuncture inhibited the development of weight gain, hyperglycemia, hyperinsulinemia, hyperlipidemia, increases of AST and ALT, and the enlargement of fat cell size induced by HFD. Also, RA herbal acupuncture inhibited the expression of PPAR-${\gamma}$, C/$EBP{\alpha}$, aP2, LPL, FAS, SCD-1 and enhanced the activation of AMP-activated protein kinase. Conclusions : The results of this study demonstrate that RA herbal acupuncture can exert the anti-obesity effect and it is partially mediated by activation of AMPK and inhibition of the gene expressions responsible for adipocyte differentiation. Further studies will be required to ascertain the nti-obesity effect and mechanisms of action of RA herbal acupuncture in animal models and human for aclinical application.

  • Dynamic modification of cytoplasmic and nuclear proteins by O-linked N-acetylglucosamine (O-GlcNAc) on Ser and Thr residues is ubiquitous in higher eukaryotes. And this modification may serve as a signaling mod-ification analogous to protein phosphorylation. Addition and cleavage of O-GlcNAc are catalyzed by O-linked GlcNAc transferase (OGT) and O-linked N-acety1glucosaminidase (O-GlcNAcase), respectively. Two types of human O-GlcNAcase gene were cloned and expressed as three fusion proteins in Escherichia coli. O-GlcNA-case activity showed in the order of thioredoxin fusion> $6{\times}His$ tag> GST fusion. O-GlcNAcase had enzy-matic activity against only ${\rho}$NP-GlcNAc of seven tested substrate analogs. Blast search revealed that O-GlcNAcase has two conserved domains, amino terminal hyaluronidase-like domain and carboxy terminal N-acetyltransferase domain. Extensive deletion studies were done to define catalytically important domains. The deletions of hyaluronidase-like domain and N-acetyltransferase domain abolished enzyme activity. But, N-ter-minal 55 amino acid deletion and C-terminal truncation showed lower activity. Based on deletion analysis, we suggest that hyaluronidase-like domain is essential for enzyme activity and carboxy terminal N-acetyltrans-ferase domain may be modulatory function.

  • Due to the lowering of biological functions resulted from old age, the elderly is known to have many different clinical laboratory data compared with the young adults. But, in korea, such study is lacking. This research is to find the differences between the elderly and the young adults, and also to know the sexual differences, by comparing the outcomes of the clinical. laboratory data. Along with that, it is to help clinical usage of the data in the future. The age of the elderly was between 60 and 83(average age 63.8), and that of the young. controls was between 20 and 35. In both sexes, MCV, MCH, ESR, CRP, AST, ALT, ${\gamma}$GTP, ALP, BUN, total cholesterol were significantly higher in the elderly than in the controls. And lymphocyte count(%), total bilirubin, direct bilirubin, total protein, albumin, $T_3$ were significantly lower in the elderly than in the controls(P<0.05). Hemoglobin, Hct, platelet count, $T_4$ were significantly lower only in the male elderly, and eosinophil count(%), creatinine were significantly higher only in the female elderly(P<0.05). HDL cholesterol was significantly higher only in the male elderly(P<0.01). There were no significant difference between two groups regarding WBC count, segment neutrophil count(%), monocyte count(%), TSH. Many clinical laboratory data are different between the elderly and the young adults, and some clinical laboratory data also have sexual differences.

  • In order to obtain basic data on the effective utilization of cockle shell, food compositions and lipid components its the raw, cooked meat and cooked meat extracts were analyzed. Cooked meat($95^{\circ}C$, 15 sec 3kg/200l water) showed a slight lower content in moisture and total crude lipid then raw meat but those meat had more crude protein and ash then raw one. Non-polar lipid of the raw, cooked meat and its extract consist of $25.4\%,\;22.4\%\;and\;48.7\%$, of total lipid, while polar lipid, $74.6\%,\;77.6\%\;and\;51.3\%$ respectively. Non-polar lipid was mainly was consisted of triglyceride, free fatty acid, and polar lipid mainly was consisted of phosphatidyl choline, phosphatidyl ethanolamine. The major fatty acids of total lipid and fractionated lipid were 20:5(n-3), 22:6(n-3), 16:0 and 18:0 in the raw, cooked meat and cooked meat extracts and showed higher contents in polyenes such as 20:5(n-3), 22:6(n-3).

  • Yam Yackwa (YP) was made by addition of yam power (15%) into flour. Depending on extension of storage time, lightness and redness of YP were increased. Yellowness of YP was decreasing until 3 days and increased from 9 days of storage. However, the yellowness of Yackwa without Yam powder (Non-YP) was increasing until 3 days and decreased from 6 days of storage. Hardness, gumminess, and chewiness of YP were improved compared to Non-YP. It means that the addition of yam power makes Yackwa soft. Oil absorption of Non-YP was low. Acid value and peroxide value of YP were 1.57 and 19.04, respectively. Moisture contents, crude ash, crude fat, crude protein, and carbohydrate of YP were $2.55{\pm}0.08%$, $0.71{\pm}0.01%$, $6.11{\pm}0.06%$, $15.97{\pm}1.40%$, and $64.66{\pm}0.09%$, respectively.

  • Gastric cancer (GC) is one of the most common malignancies in the world. It is the first cause of cancer deaths in both sexes In Iranian population. Circulating insulin-like growth factor-one (IGF-1) levels have been associated for gastric cancer. IGF-1 protein has central roles involved in the regulation of epithelial cell growth, proliferation, transformation, apoptosis and metastasis. Single nucleotide polymorphism in IGF-1 regulatory elements may lead to alter in IGF-1expression level and GC susceptibility. The aim of this study was to investigate the influence of IGF-1 gene polymorphism (rs5742612) on risk of GC and clinicopathological features for the first time in Iranian population. In total, 241 subjects including 100 patients with GC and 141 healthy controls were recruited in our study. Genotypes were analyzed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay with DNA from peripheral blood. The polymorphism was statistically analyzed to investigate the relationship with the risk of GC and clinicopathological properties. Logistic regression analysis revealed that there was no significant association between rs5742612 and the risk of GC. In addition, no significant association between genotypes and clinicopathological features was observed (p value>0.05). The frequencies of the CC, CT, and TT genotypes were 97%, 3%, and 0%, respectively, among the cases, and 97.9%, 2.1%, and 0%, respectively, among the controls. CC genotype was more frequent in cases and controls. The frequencies of C and T alleles were 98.9% and 1.1% in controls and 98.5% and 1.5% in patient respectively. Our results provide the first evidence that this variant is rare in Iranian population and it may not be a powerful genetic predisposing biomarker for prediction GC clinicopathological features in an Iranian population.

  • Atopic dermatitis is a chronic, relapsing inflammatory skin disease associated with dysfunction of skin barrier and cutaneous hyper-reactivity to environmental triggers. In the previous study, cytotoxicity, antioxidant, anti-inflammatory and anti-allergic activities were investigated for various herbal extracts such as Aloe vera L. (AV), Viola mandshurica W. Becker (VM), Punica granatum L. (PG), and Dendrobium nobile L. (DN) in order to develop effective therapeutic herbal extracts for atopic dermatitis, In this study, anti-inflammatory activities of these herb extracts in lipopolysaccharide (LPS)-induced macrophage RAW264.7 cells were further examined to find the underlying molecular mechanisms. The RT-PCR (reverse transcription polymerase chain reaction) analysis showed that PG, DN and AV inhibited effectively the gene expression of pro-inflammatory cytokines IL-6 and IL-$1{\beta}$ in LPS-stimulated macrophages, while VM did not. The transfection and luciferase analysis exhibited that all herbal extracts hindered the activation of transcription nuclear factor kappa B (NF-${\kappa}B$). The western blot analysis indicated that AV blocked the activation of only JNK MAP (c-Jun N-terminal kinase mitogen-activated protein) kinase not p38 MAP kinase, while VM, PG and DN did not show the activation of both JNK and p38 MAP kinases. These results suggest that AV, VM, PG, and DN have anti-inflammatory activities and thus have the potential to reduce and alleviate the symptoms of atopic dermatitis.

  • This study aimed to assess the total sugar intake for Korean and to identify major food sources contributing to those food components. Korean adults aged over 20 years old from the Korean National Health and Nutrition Examination Survey (KNHANES) 2001 and 2002 were selected. The data were analyzed to obtain nationally and seasonally representative information on the health and nutritional status of the Korean. Forty food groups were used in identifying food sources of total sugar and energy intake. Total sugar contents of foods in the KNHANES data sets were estimated by food code matching technique with Release 18 of the USDA National Nutrient Database for Standard Reference. Sample weighted means, standard errors, and population percentages were calculated using SAS and SUDAAN. The mean total sugar intake of the Korean was 60.3g in 2001, 40.9g in spring 2002, 45.7g in summer 2002, and 52.1g in fall 2002, which were 30-44% of intake of US people. Fresh fruit was identified as the most significant food source for total sugar intake in Korean population in all age groups and all seasons. The next major food sources following fresh fruits were candy/jelly/syrup/honey, coffee/coffee caream, vegetables, Kimchi, soft drinks, milk, fruit juice, cookie/cracker/cake, and vegetable juice/grain juice, which showed similar results through the seasons. While carbonated soft drink was the most significant food sources for total sugar or added sugar intakes for US people. The total sugar intakes were significantly higher in women, higher educational level, and residing in metropolitan area. As intake of total sugar increased, intakes of protein, fiber, calcium, phosphorus, iron, Vit A, B1, B2, C, niacin showed significantly increased, while high intakes of added sugars showed low intakes of some micronutrients in the US people. Percentages of people who consumed nutrients below EAR were less in higher total sugar intake group than in lower intake group. From these results, we can conclude that the food consumption habits including the total sugar intake of Korean people seems relatively good so far. More reliable database of total sugar and added sugar composition tables in public domain should be established in the future, and also more researches about total sugar and added sugar for Koreans should be continued.

  • Purpose: This study investigated the factors affecting the use of empirical antibiotics in febrile infants from 1 month to less than 3 months. Methods: We retrospectively reviewed the medical records of hospitalized previously healthy infants with fever in Pusan National University Children's Hospital from January 2010 to December 2016. Clinical features, laboratory findings and antibiotic therapy were analyzed. Respiratory viruses were identified by multiplex reverse transcriptase polymerase chain reaction (RT-PCR) and were reported after 1-3 days. Enterovirus were identified by real time polymerase chain reaction (PCR) and were reported in several hours. Results: The 129 of 366 subjects used empirical antibiotics and 237 patients didn't used empirical antibiotics. Empirical antibiotics were used more frequently when the fever was longer before admission, respiratory symptoms and ill being appearances were present and C-reactive protein was elevated. The rate of readmission was low in the group not used empirical antibiotics. Most of the patients detected by enterovirus PCR in cerebrospinal fluid didn't used empirical antibiotics. The results of respiratory virus multiplex RT-PCR showed no difference in the use of empirical antibiotics. Conclusions: In our study, empirical antibiotic prescriptions were affected not respiratory virus multiplex RT-PCR but enterovirus PCR. If multiplex RT-PCR were reported more rapid turn around time, it will affect antibiotic use.
