This study was conducted to investigate the effects of mulberry fruit, mulberry leaves and silkworm powder with different mixing ratios on hepatic antioxidative system and lipid metabolism in streptozotocin-induced diabetic rats. Sprague-Dawley male rats weighing 100+/-10 g were induced diabetic by 50 mg/kg bw streptozotocin and randomly assigned to following experimental groups; normal diet group (DM) , 0.3% and 0.6% mulberry fruit diet groups (F and 2F) , 0.3% mulberry leaves diet group (M) , 0.3% silkworm powder diet group (S), 0.15% mulberry fruit + 0.15% mulberry leaves diet group (FM), 0.15% mulberry fruit + 0.15% silkworm powder diet group (FS) , 0.1% mulberry fruit + 0.1% mulberry leaves + 0.1% silkworm powder diet group (FMS) . The experimental diets were fed for 4 weeks. Hepatic SOD activity was not changed significantly by any of single or combined supplementations of mulberry fruit, leaves and silkworm powder but GSH-px and catalase activities were increased by the groups supplemented with two or three of the test ingredients (FM, FS, FMS) as compared with the DM group. Hepatic TBARS value was not reduced significantly by any of the supplementations but lipofuscin contents were significantly reduced in the FM, FS and FMS groups as compared with the DM group. Hepatic mitochondria and microsomal carbonyl values were reduced by the single and combined supplementations of the test ingredients. Hepatic HMG-CoA reductase activities were increased in the all supplementation groups as compared with the DM group. Hepatic total lipid and triglyceride contents were increased but cholesterol contents reduced in the supplemented groups. The effects on the enzyme activities, peroxide or its products and lipid contents were most remarkable in the FMS group. In conclusion, mulberry fruit, mulberry leaves and silkworm powder have the favorable effects on antioxidative system and lipid metabolism in the diabetic liver and the mulberry fruit, leaves and silkworm powder with equal ratio exert the synergistic effect expectedly to prevent diabetic complications.

BACKGROUND/AIMS: The clinical outcomes of patients with hematologic malignancies who were treated with extracorporeal membrane oxygenation (ECMO) after the failu re of optimal conventional therapy were determined. METHODS: The medical records of all patients administered ECMO during their stay in a medical intensive care unit of Seoul St. Mary's Hospital between February 2010 and July 2013 were reviewed retrospectively. RESULTS: In total, 15 patients with hematologic malignancies were compared to 33 immunocompetent patients with documented cardiorespiratory failure. Underlying hematologic malignancies were significantly associated with lower overall survival (0.0% vs. 24.2%, p = 0.044). Mortality was significantly associated with a higher 24 hours ECMO inspired fraction of oxygen (0.71 +/- 0.24 vs. 0.47 +/- 0.13, p = 0.015), the development of infection after ECMO (87.5% vs. 25.0%, p = 0.001), and the presence of hyperbilirubinemia (70.0% vs. 0.0%, p < 0.001). Matching of the patients based on their Acute Physiology and Chronic Health Evaluation II scores confirmed the greater risk of mortality in patients with hematologic malignancies (survival: 0.0% vs. 40.0%, p = 0.017). The mean difference in inotropic-equivalent scores after ECMO was significantly lower in the immunocompetent patients than in those with hematologic malignancies (-59.22 +/- 97.83 vs. 53.87 +/- 164.46, p = 0.026). CONCLUSIONS: Patients with hematologic malignancies who require ECMO for respiratory support have poor outcomes. The incidence of complications in these patients did not significantly differ from that in immunocompetent patients.

OBJECTIVE: Heart rate variability(HRV) is helpful to diagnosis autonomic disturbance and sympathetic-parasympathetic imbalance in patients with myocardial infarction and diabetes mellitus. Patients with liver cirrhosis demonstrate reduced blood pressure despite increased heart rate and increased cardiac output, indicating a fall in peripheral vascular resistance. Autonomic disturbance may contribute to this phenomenon. The aim of the present study is to evaluate the degree of autonomic disturbance and the circadian rhythm of autonomic nervous system by estimating HRV with 24 hour-Holter recorder, METHODS: 24 hour-HRV with Del Mar Avionics 563 Holter recorder and cardiovascular reflex tests were carried out on 32 patients with liver cirrhosis and 20 control subjects. We evaluated the presence of autonomic disturbance, and assessed quantitatively the autonomic disturbance. RESULTS: 1) Among cardiovascular reflex tests, Valsalva test, standing test and deep breathing test were showed a significantly decreased response in liver cirrhosis compared with control groups. 2) The standard deviation of 24hours average R-R intervals were showed a significantly decrease in liver cirrhosis than control groups(P<0.0001). The HRV of low frequency(LF. P<.D.001), high frequency(HF, P<0.0001) and total power spectral density (P<0.0001) in liver cirrhosis were statistically lower than control. 3) The LF/HF ratio of patients with liver cirrhosis was showed higher than control at night CONCLUSION: Non-invasive assessment of 24 hour-HRV has a few advantages in the diagnosis and degree of autonomic disturbance, evaluation of diurnal variation of autonomic tone.

The present study evaluated the response of blood pressure (BP) by dietary sodium in sodium resistant (SR) subjects. One hundred one subjects (mean age, 46.0 yr; 31 hypertensives) were admitted and given low sodium-dietary approaches to stop hypertension (DASH) diet (LSD, 100 mM NaCl/day) for 7 days and high sodium-DASH diet (HSD, 300 mM NaCl/day) for the following 7 days. On the last day of each diet, 24 hr ambulatory BP was measured. Morning systolic BP (SBP) and diastolic BP (DBP) were elevated after HSD in all subjects (P < 0.01), but daytime SBP and DBP were not changed (P > 0.05). In hypertensive subjects, morning DBP elevation was greater than daytime DBP elevation (P = 0.036), although both DBPs were significantly elevated after HSD. The augmented elevation of morning DBP in hypertensive subjects was contributed by the absolute elevation of morning DBP (P = 0.032) and relative elevation to daytime DBP (P = 0.005) in sodium resistant (SR) subjects, but not by sodium sensitive subjects. Although there was no absolute elevation, SR subjects with normotension showed a relative elevation of morning SBP compared to daytime SBP change after HSD (P = 0.009). The present study demonstrates an absolute and relative elevation of morning BP in SR subjects by HSD.

BACKGROUND: Epidermal Growth Factor (EGF) is one of the important growth factors involved in the epithelialization during cutaneous wound healing. Peptide EGF has been used for the treatment of diabetic foot ulcer. But the inferiority of cost-effectiveness and the inconvenience of daily application might have restricted its wide clinical usage. EGF gene therapy could dramatically improve the efficacy and inconvenience through long-term expression and bypassing the EGF degradation by hostile non-specific proteinases expressed in the wound bed. METHODS: EGF DNAs were amplified via PCR. For the more effective secretion from the transfected cell, we inserted furin cleavage site into EGF plasmids. The efficacy of novel plasmid pbeta-EGF was verified by transfection into the various animal cell lines, and the biologic potency of expressed EGF was confirmed via phosphorylation of PI3K and GSK3beta by Western blotting. RESULTS: We tested various kinds of human EGFs. One of the human EGF isoforms, EGF(828) including a membrane-anchoring domain was successfully released as the mature EGF protein in the cell culture media. Also EGF plasmid including furin cleavage site showed more than 2-fold increased EGF expression compared with the sequence without furin cleavage site. CONCLUSION: In conclusion, these findings suggest that mature EGF could be released easily out of cells by modifying EGF DNA sequence. Our novel EGF plasmid DNA could markedly increase the efficiency of non-viral gene therapy for diabetic foot ulcer.

BACKGROUND/AIMS: Inhaled corticosteroids are the most effective treatment currently available for asthma, but their beneficial effect against airway remodeling is limited. The tyrosine kinase inhibitor nilotinib has inhibitory activity against c-kit and the platelet-derived growth factor receptor. We compared the effects of fluticasone and nilotinib on airway remodeling in a chronic asthma model. We also examined whether co-treatment with nilotinib and fluticasone had any synergistic effect in preventing airway remodeling. METHODS: We developed a mouse model of airway remodeling, including smooth muscle thickening, in which ovalbumin (OVA)-sensitized female BALB/c-mice were repeatedly exposed to intranasal OVA administration twice per week for 3 months. Mice were treated with fluticasone and/or nilotinib intranasally during the OVA challenge. RESULTS: Mice chronically exposed to OVA developed eosinophilic airway inflammation and showed features of airway remodeling, including thickening of the peribronchial smooth muscle layer. Both fluticasone and nilotinib attenuated airway smooth muscle thickening. However, only nilotinib suppressed fibrotic changes, demonstrating inhibition of collagen deposition. Fluticasone reduced pro-inflammatory cells, such as eosinophils, and several cytokines, such as interleukin 4 (IL-4), IL-5, and IL-13, induced by repeated OVA challenges. On the other hand, nilotinib reduced transforming growth factor β1 levels in bronchoalveolar lavage fluid and inhibited fibroblast proliferation significantly. CONCLUSIONS: These results suggest that fluticasone and nilotinib suppressed airway remodeling in this chronic asthma model through anti-inflammatory and anti-fibrotic pathways, respectively.

The aim of this study was to investigate the effects of mulberry juice and cake powder on blood glucose and lipid status along with intestinal disaccharidase and erythrocyte antioxidative enzyme system in streptozotocin (STZ )-induced diabetic rats. Sprague-Dawley male rats weighing 100 +/- 10 g were randomly assigned to one normal group, and eight STZ-induced diabetic groups: control diet group without mulberry juice and cake powders (DM-C ), three mulberry juice powder groups (0.5%:DM-0.5J, 1%:DM-1J, 2%:DM-2J )and four mulberry cake powder groups (0.25%:DM-0.25C, 0.5%:DM-0.5C, 1%:DM-1C, 2%:DM-2C ). After three-week feeding of each experimental diet, diabetes was induced by intravenous injection of 50 mg/kg body weight of STZ in sodium citrate buffer (pH 4.3 )via tail vein of eight DM groups. Rats were sacrificed at the 9th day of diabetic states. Level of blood glucose was 505 mg/dl in DM-C group but it was 28% and 39% lower in mulberry juice and cake powder fed groups, respectively, than the DM-C group. Activities of maltase, sucrase and lactase in proximal part of small intestine were significantly lower in the mulberry juice and cake powder groups by 42~47% than those of DM-C group. Erythrocytic superoxide dismutase, glutathione peroxidase and catalase activities were significantly reduced by STZ but increased close to normal levels along with less accumulation of thiobarbituric acid reactive substances (TBARS ). Serum levels of triglyceride and total cholesterol and HDL-cholesterol by STZ-DM were reduced and increased respectively, to the normal levels by the mulberry juice and cake powder. Except the levels of TBARS, the effects on the other measure-ments by the various dietary levels of mulberry juice and cake powder were almost same and the effect of the cake powder was most significant at the lowest level. These results indicate that mulberry juice and cake powders have considerable hypoglycemic effect and strengthening antioxidant defense systems at the low levels in diabetic state and may be able to reduce diabetic complications.

The Korean Society of Neurogastroenterology and Motility first published guidelines for chronic constipation in 2005 and was updated in 2011. Although the guidelines were updated using evidence-based process, they lacked multidisciplinary participation and did not include a diagnostic approach for chronic constipation. This article includes guidelines for diagnosis and treatment of chronic constipation to realistically fit the situation in Korea and to be applicable to clinical practice. The guideline development was based upon the adaptation method because research evidence was limited in Korea, and an organized multidisciplinary group carried out systematical literature review and series of evidence-based evaluations. Six guidelines were selected using the Appraisal of Guidelines for Research & Evaluation (AGREE) II process. A total 37 recommendations were adopted, including 4 concerning the definition and risk factors of chronic constipation, 8 regarding diagnoses, and 25 regarding treatments. The guidelines are intended to help primary physicians and general health professionals in clinical practice in Korea, to provide the principles of medical treatment to medical students, residents, and other healthcare professionals, and to help patients for choosing medical services based on the information. These guidelines will be updated and revised periodically to reflect new diagnostic and therapeutic methods.
