Root extract of Lythrum salicaria reported a hepato-protective effect on $CCl_4$-induced liver toxicity of rat was prepared into fractions such as n-hexane up layer (HA), n-hexane down layer (HB), diethyl ether (E), ethylacetate (EA), n-butanol (B) and water (W). Fractions prepared were tested their activities in vitro and in vivo condition. All of the fractions showed effective antioxidant asctivities on DPPH radical and $CuSO_4$-induced oxidation of human low density lipoprotein and E fraction showed the highest inhibitory effect (98.1% at $50\;{\mu}g/m{\ell}$) on linoleic acid autoxidation at $40^{\circ}C$, which was more effective than $\alpha$-tocopherol (82.4%). Five fractions (H = HA plus HB, E, EA, B, and W, 150 mg/kg/day) were fed into Sprague Dawley, male rats for 4 days, which were intoxicated with intra-peritoneal injection of carbon tetrachloride ($1\;m{\ell}/kg$ in corn oil) at the 4th day and were sacrificed in 24 hrs. Serum tumor necrosis factor-alpha (TNF-$\alpha$), a proinflammatory cytokine, elevated with $CCl_4$-intoxication in negative control group ($83\;pg/m{\ell}$) was significantly decreased in E fraction-supplemented group ($18\;pg/m{\ell}$). Cu, Zn-superoxide dismutase (SOD) activity increased in negative control group (0.12 U/mg protein) was decreased in E fraction (0.07 U/mg protein). From the results, it is suggested that ether fraction from root extract of L. salicaria would be a potent antioxidant candidate for ameliorating liver injury induced by chemical intoxicant.

The purpose of this study was to investigate the effect of carotid artery ultrasound Respectively. The carotid intima-media thickness is known to have a significant correlation with cardiovascular disease and cerebrovascular disease. We investigated the relationship between carotid intima - media thickness, body mass index, waist circumference, the blood lipid value, fasting blood glucose, glycated hemoglobin, and blood pressure using carotid artery ultrasound. The carotid artery ultrasound was considered to be abnormality of IMT thickness over 0.8 mm and the presence or absence of atherosclerotic plaque was evaluated. Serological tests were used to compare the geologic value, fasting blood glucose level, and glycated hemoglobin. As a result, waist circumference (=.022), low density cholesterol (=.004), fasting blood glucose level (.019), and glycemic index (.002) were analyzed as predictors of atherosclerosis. In the ROC curve analysis, sensitivity was 87.80% (95% CI: 73.8-95.9), specificity was 41.67% (95% CI: 30.2-53.9), sensitivity was 78.05% (95% CI: 62.4-89.4) in low density lipoprotein, Specificity was 50.00% (95% CI: 38.0-62.0), sensitivity was 73.11% (95% CI: 57.1-85.8), specificity was 61.11 (95% CI: 48.9-72.4) and sensitivity was 82.93%-91.8) and a specificity of 43.06% (31.4-55.3). In logistic regression analysis, the risk of atherosclerosis was 0.248 times at waist circumference (WC)> 76 cm, 3.475 times at low-density lipoprotein (LDL-C) ${\geq}124mg/dL$, 0.618 at HbA1c> 5.4% It appeared as a times. We suggest that prospective study of carotid artery ultrasound should be performed for the effective prevention of cardiovascular diseases.

An intravenous pharmacokinetics for a new red cell substitute, PEG-hemoglobin SB1, was studied in SD rats. Total-hemoglobin and its metabolite methemoglobin in the plasma were determined using a spectrophotometer. The limit of quantitation was 0.01g/dL and the C.V for interday assay reproducibility was less than 6%. Upon intravenous administration of anticipated clinical dose, 10 ml(0.7 gHb)/kg, plasma concentration curve of total-hemoglobin was well described by one-compartment model. The $t_{\frac{1}{2}},{\;}CL_{t}$, Vd and $AUC^{0-48hr}$ were $8.23{\pm}0.96{\;}hr,{\;}0.06{\;}{\pm}{\;}0.01 {\;}dL/hr/kg,{\;}0.66{\pm}0.05{\;}dL/lg{\;}and{\;}13.6{\;}{\pm}{\;}1.01g{\cdot}hr/dL$, respectively, in male rats(n=5, $mean{\;}{\pm}{\;}SD$). Those parameters in female rats were $9.21{\;}\pm{\;}2.31{\;}hr,{\;}0.06{\;}{\pm}{\;}0.01{\;}dL/hr/kg,{\;}0.79{\pm}{\;}0.08{\;}dL/kg{\;}and{\;}13.0{\;}{\pm}{\;}2.36{\;}g{\cdot}hr/dL$, respectively. Similar kinetic profiles between males and females were also obtained from other parameters. Small amount of methemoglobin, an oxidative metabolite of SB1, was detected in the plasma of both sexes, where the $AUC^{0-48{\;}hr,m}$ and $t_{{\frac{1}{2}},m}$ were approximately $1.5{\;}g{\cdot}hr/dL$ and 20 hr, respectively. The present work provides a critical kinetic data for the effective clinical applications of PEG-hemoglobin SB1.

Treatment of obesity includes diet therapy, exercise therapy, cognitive behavioral therapy, drug therapy, and bariatric surgery. Most obese patients lose weight by combining diet, exercise, cognitive behavioral therapy or medication. But, in some cases, only one of these treatments is preferred. A 56-year-old male patient had a body mass index (BMI) of 33.1 kg/m² and a waist circumference of 108 cm. He had been treated for hypertension; diabetes and dyslipidemia were diagnosed but not treated. However, at the initial visit to treat obesity, he was diagnosed with type 2 diabetes mellitus and dyslipidemia again. So he decided to treat these two diseases with drugs first and modify his lifestyle. He started walking more than 20,000 steps every day and then he really walked about 15,000 steps every day during 5 months, although diet calorie or alcohol drinking amount was not significantly decreased. After about 6 months, the patient's weight decreased by 10.1 kg, the BMI decreased by 4.1 kg/m², the waist circumference decreased by 10 cm, the glycated hemoglobin (HbA1c) decreased by 4.59%, the visceral fat area decreased by 115 cm², and the subcutaneous fat decreased by 38 cm². As a result of body composition analysis, muscle mass increased by 1.2 kg, and the percentage of body fat decreased by 10.4%. The walking exercise does not have any space restrictions and has high accessibility by using a mobile phone app. Therefore, considering the patient's situation, it would be better to treat obese patients by first recommending walking exercises and increasing the number of steps to lose weight and improve the comorbidities.

This study was carried out to develop a resistant variety against the K3a race of bacterial blight, Xanthomonas oryzae pv. oryzae, through expansion and pyramiding of resistance genes. To develop an elite bacterial blight-resistant cultivar, the breeding process and bacterial blight resistance reactions in advanced backcross lines (ABLs) were analyzed. ABLs21 which contain Xa3 and Xa21, were developed by double backcrossing japonica cultivar Hwanggeumnuri, which has bacterial blight resistant Xa3 gene, and indica variety IRBB21, which havs Xa21 gene, followed by disease resistance bioassay and marker-assisted selection. The resistance genes of ABLs21 were amplified by PCR with the molecular markers 9643.T4 (Xa3) and U1/I1 (Xa21). Hwanggeumnuri and IRBB3 showed resistance reactions against K1, K2, and K3 races, and a susceptible reaction against K3a, K4, and K5 races. IRBB21 showed resistance reactions against K2, K3, K3a, K4 and K5 races, and a susceptible reaction against K1 race. Hwanggeumnuri showed susceptible reactions at the seedling, tillering and adult stages (all stages), whereas ABL21-1 showed moderate resistance at the tillering stage. ABL21-1 showed stable resistance against 18 isolates of K3a race, and the lesion length was shorter than that of the donor parents. In cluster analysis, the HB4032 isolate showed the highest pathogenicity among the 18 isolates. The molecular marker polymorphisms and average substituted chromosome segment lengths of ABLs21 were 63.2 % and 86.1 cM, respectively. Insertion of the donor chromosomal segments occurred in the predicted region of the Xa21 gene of ABLs21.

Purpose: This study compared and analyzed the risk factors that affect a wound healing group and healing failure group. Materials and Methods: From 2010 to 2018, 39 patients who had suffered a single toe amputation were evaluated retrospectively. The patients were divided into two groups (wound healing group and healing failure group - within at least 3 months following the amputation). Regarding the possible risk factors, age, gender, Wagner and Brodsky classifications, duration of diabetes mellitus, whether the patient had peripheral arterial occlusive disease (PAOD) or cardiovascular disease, body mass index, HbA1c, total cholesterol, estimated glomerular filtration rate (eGFR), blood urea nitrogen (BUN), smoking, and alcohol were investigated. Results: The mean duration of diabetes mellitus was 140 months in the healing group and 227 months in the healing failure group, and the duration of diabetes was significantly longer in the failure group (p=0.009). A significant difference in eGFR was observed between the two groups ($59.17mL/min/1.73m^2$ in the healing group and $31.1mL/min/1.73m^2$ in the failure group) (p=0.022). Sixteen patients with PAOD were found, all 10 patients in the healing failure group were PAOD patients. Conclusion: To reduce the additional complications in single toe amputation patients, the underlying disease and appropriate treatment are the most important factors. In addition, a more proximal level of amputation also should be considered in cases of patients with PAOD, high BUN and low eGFR, and patients with long-term diabetes.

Fermented ginseng (FG) is an ethanol extract of ginseng radix processed with $\beta$-galactosidase. It was hypothesized that FG may exert anti-hyperlipidemic and anti-diabetic activities through modulating AMP-activated protein kinase (AMPK) in HepG2 human hepatoma cells. In this study, we showed that AMPK phosphorylation was stimulated by FG. These effects were abolished by pretreatment with an AMPK inhibitor, compound C. In addition, FG regulated the expression of genes associated with lipogenesis and lipolysis, thus causing suppression of hepatic triglyceride accumulation. In vivo study using db/db mice, FG reduced fasting plasma glucose, HbAlc, and insulin resistance index, when compared to diabetic control. FG also increased the phospho-AMPK and glucose transporter 4 (GLUT4) expressions in liver and skeletal muscle, respectively. In liver, expressions of lipogenic gene were decreased whereas expressions of lipolytic genes were induced, when compared to diabetic control. Taken together, we may suggest that FG ameliorates hyperglycemia and hyperlipidemia through activation of AMPK and could be developed as a health functional food or therapeutic agent for type 2 diabetic patients.

Purpose: Study purposes were to exam effects of self-care education for children with type 1 diabetes on their diabetes management behaviors and to explore the relationship among diabetes management behaviors, knowledge, self-efficacy and clinical variables. Methods: This study was a one group quasi-experimental study. Study participants were children with type 1 diabetes and attended a four hour self-care education of a diabetes camp. Data were collected using structured questionnaires including Diabetes Management Behavior Scale (DMBS), Michigan Diabetes Research and Training Center's Brief Diabetes Knowledge Test and Self-Efficacy for Diabetes Self-Management. Results: The mean age of the participants was 12 (${\pm}2.3$) years. After the education, their DMBS and knowledge improved, but the improvement was not statistically significant (t=1.758, p=.101; t=0.528, p=.606). Two areas of DMBS, daily prevention behaviors and modification of care plan, were associated with study variables. Daily prevention behaviors were associated with duration of diabetes (r=.653, p=.008), HbA1c (r=.563, p=.038) and having a complication (r=-2.788, p=.015). Modification of care plan was associated with age at diagnosis (r=-.552, p=.033). Conclusion: Children with type 1 diabetes could improve some parts of their diabetes management behaviors even after a short diabetes camp.
