PURPOSE: Liver metabolism plays a pivotal role in the development of metabolic disorders. We aimed to investigate the clinical and laboratory risk factors associated with alanine aminotransferase (ALT) levels in young adolescents from an urban population in Korea. METHODS: A population of 120 apparently healthy adolescents aged 12–13 years was included in the cross-sectional design study; 58 were overweight or obese and 62 were of normal weight. We estimated anthropometric and laboratory measurements, including waist-to-height ratio, blood pressure, insulin sensitivity, aspartate aminotransferases (AST), ALT, and lipid profiles. RESULTS: The mean ages of the overweight or obese and normal weight participants were 12.9±0.3 and 13.0±0.3 years, respectively. Height, weight, body mass index, waist circumference, waist-to-height ratio, systolic and diastolic blood pressure, AST, ALT, total cholesterol, low-density lipoprotein-cholesterol, triglyceride, insulin, and the homeostatic model assessment of insulin resistance (HOMA-IR) score were significantly higher and the high-density lipoprotein-cholesterol and quantitative insulin-sensitivity check index were significantly lower in the overweight/obese participants in comparison to the normal-weight participants (all P < 0.05). In multivariate linear regression analysis, waist-to-height ratio, systolic blood pressure, and HOMA-IR score were independently and positively associated with serum ALT levels. CONCLUSION: Screening for ALT levels in adolescents may help to differentiate those at risk of metabolic abnormalities and thus prevent disease progression at an early age.

BACKGROUND/OBJECTIVES: Oxidative stress is caused by an imbalance between harmful free radicals and antioxidants. Long-term oxidative stress can lead to an “exhausted” status of antioxidant defense system triggering development of metabolic syndrome and chronic inflammation. Green perilla (Perilla frutescens) is commonly used in Asian cuisines and traditional medicine in southeast Asia. Green perilla possesses numerous beneficial effects including anti-inflammatory and antioxidant functions. To investigate the potentials of green perilla leaf extract (PE) on oxidative stress, we induced oxidative stress by high-fat diet (HFD) in aging mice.MATERIALS/METHODS: C57BL/6J male mice were fed HFD continuously for 53 weeks.Then, mice were divided into three groups for 12 weeks: a normal diet fed reference group (NDcon), high-fat diet fed group (HDcon), and high-fat diet PE treated group (HDPE, 400 mg/kg of body weight). Biochemical analyses of serum and liver tissues were performed to assess metabolic and inflammatory damage and oxidative status. Hepatic gene expression of oxidative stress and inflammation related enzymes were evaluated by quantitative real-time polymerase chain reaction (qRT-PCR). RESULTS: PE improved hepatopathology. PE also improved the lipid profiles and antioxidant enzymes, including hepatic glutathione peroxidase (GPx) and superoxide dismutase (SOD) and catalase (CAT) in serum and liver. Hepatic gene expressions of antioxidant and antiinflammatory related enzymes, such as SOD-1, CAT, interleukin 4 (IL-4) and nuclear factor erythroid 2-related factor (Nrf2) were significantly enhanced by PE. PE also reduced the levels of hydrogen peroxide (H 2 O 2 ) and malondialdehyde (MDA) in the serum and liver;moreover, PE suppressed hepatic gene expression involved in pro-inflammatory response;Cyclooxygenase-2 (COX-2), nitric oxide synthase (NOS), interleukin 1 beta (IL-1β), and interleukin 6 (IL-6). CONCLUSIONS This research opens opportunities for further investigations of PE as a functional food and possible anti-aging agent due to its attenuative effects against oxidative stress, resulting from HFD and aging in the future.

Chronic actinic dermatitis is a rare disease worldwide and also in Korea. However there has been no clinicohistologic and photobiological analysis of chronic actinic dermatitis in Korea. We examined 11 patients who were diagnosed as chronic actinic dermatitis and the results of this study were compared with previous reports. Most patients were elderly men who had erythematous papules or lichenified plaques on sun-exposed areas such as the face, neck, and dorsum of the hands with severe itching sensation. All patients had severe sensitivity to UVB and biopsied specimens showed findings of chronic eczema. Five patients had positive photopatch test materials. The patients were treated with systemic and topical steroid, cyclosporine and antihistamine.

BACKGROUND: Oral tolerance is defined by the inhibition of immune responsiveness to a protein previously exposed via the oral route. Protein antigens exposed via the oral route can be absorbed through the mucosal surfaces of the gastrointestinal tract and can make physical contact with immune cells residing in the intestinal lamina propria (LP). However, the mechanisms of oral tolerance and immune regulation in the intestines currently remain to be clearly elucidated. METHODS: In order to determine the effect of oral protein antigen intake (ovalbumin, OVA) on the intestinal LP, we assessed the expression profile of the T cell receptor and the co-receptors on the cells from the intestines of the tolerant and immune mouse groups. RESULTS: We determined that the proportion of OVA-specific B cells and gamma delta T cells had decreased, but the CD8alpha beta and CD8alpha alpha T cells were increased in the LP from the tolerant group. The proportion of CD8+ T cells in the spleen did not evidence any significant differences between treatment groups. CONCLUSION: These results indicate that CD8+ T cells in the intestinal LP may perform a regulatory role following antigen challenge via the oral route.

PURPOSE: This study examines the difference of optimism, self-esteem and depression to verify an effect of laughter therapy program for menopausal women. METHODS: A quasi-experimental nonequivalent control group pre / post-test design was used. The participants (n=57) were 28 in the experimental group and 29 in the control group. The data were collected in December of 2011. The experimental group participated in laughter therapy for 30 min per session, five times a week for the period of 2 weeks. The questionnaires were used to measure pre / post-test optimism, self-esteem, and depression of menopausal women. RESULTS: The results showed that laughter therapy was effective in increasing optimism (p=.020) and self-esteem (p<.001). And the depression of menopausal women decreased (p=.003). CONCLUSION: The result of the study indicates that laughter therapy for menopausal women may be an effective nursing intervention to improve optimism, self-esteem and depression of menopausal women.

Objective: The purpose of this study was to verify the validity and reliability of Korean elderly by translating the Hayling Test, a test that measures semantic inhibition ability among executive functions. Methods: Total 91 participants were recruited in accordance with inclusion criteria and exclusion criteria for each group. Within them, 34 were normal from Dongjak-gu, Seoul, 29 were mild cognitive impairment (MCI) from clinics located in Seoul, and 28were Alzheimer’s disease (AD) from clinics located in Seoul, respectively. The one-way analysis of covariance, the Bonferroni veri-fication, the receiver operating characteristic (ROC) curve analysis, and the Brain Imaging analysis of voxel-based morphometrywere conducted in order to compare and analyze performance of demographics characteristics of each group, Hayling Test results, and The Continuous Performance Test-X (CPTX) results. Results: The comparison analysis showed the Hayling Test is more valid methodology than the CPTX test in discriminating nor-mal, MCI, and AD. Furthermore, ROC curves between normal and AD groups also demonstrated higher sensitivity (88%) and specificity (73%) of Hayling Test, and confirmed its diagnostic validity. In line with the above, brain imaging analysis displays sig-nificant positive correlation between temporal & frontal brain regions through the Hayling Test scores, however, this correlationwas not found for CPTX. Conclusion It is expected that the Haling Test, which measures language inhibition function, can be used simply and usefully in diagnosing dementia.

BACKGROUND/OBJECTIVES: Different fatty acids exert different health benefits. This study investigated the potential protective effects of perilla, olive, and safflower oils on high-fat diet-induced obesity and colon inflammation.MATERIALS/METHODS: Five-week old, C57BL/6J mice were assigned to 5 groups: low-fat diet (LFD), high-fat diet (HFD) and high-fat diet supplemented with-perilla oil (HPO), olive oil (HOO), and safflower oil (HSO). After 16 weeks of the experimental period, the mice were sacrificed, and blood and tissues were collected. The serum was analyzed for obesity- and inflammation-related biomarkers. Gene expression of the biomarkers in the liver, adipose tissue, and colon tissue was analyzed. Micro-computed tomography (CT) analysis was performed one week before sacrifice. RESULTS: Treatment with all the three oils significantly improved obesity-induced increases in body weight, liver weight, and epididymal fat weight as well as serum triglyceride and leptin levels. Treatment with perilla oil (PO) and safflower oil (SO) increased adiponectin levels. The micro-CT analysis revealed that PO and SO reduced abdominal fat volume considerably. The mRNA expression of lipogenic genes was reduced in all the three oilsupplemented groups and PO upregulated lipid oxidation in the liver. Supplementation of oils improved macroscopic score, increased colon length, and decreased serum endotoxin and proinflammatory cytokine levels in the colon. The abundance of Bifidobacteria was increased and that of Enterobacteriaceae was reduced in the PO-supplemented group. All three oils reduced proinflammatory cytokine levels, as indicated by the mRNA expression. In addition, PO increased the expression of tight junction proteins. CONCLUSIONS Taken together, our data indicate that the three oils exert similar anti-obesity effects. Interestingly, compared with olive oil and SO, PO provides better protection against high-fat diet-induced colon inflammation, suggesting that PO consumption helps manage inflammation-related diseases and provides omega-3 fatty acids needed by the body.

Purpose: This study examined the effects of Sargassum horneri extracts on palmitic acid (PA)-induced endoplasmic reticulum (ER) stress in HepG2 cells. Methods: HepG2 cells were treated with varying concentrations of S. horneri extract or PA, and the cell viability was measured by water soluble tetrazolium salts analysis. The effective induction of ER stress and the effects of S. horneri were investigated through an examination of the ER stress-related genes, such as activating transcription factor 4 (ATF4), X-box binding protein (XBP1s), C/EBP homologous protein (CHOP), and 78-kDa glucose-regulated protein (GRP78) by quantitative reverse transcription polymerase chain reaction. The expression and activation levels of unfolded protein response (UPR) associated proteins, such as inositolrequiring enzyme-1α (IRE1α), eukaryotic translation initiation factor 2 alpha submit (eIF2α), and CHOP were examined by western blot analysis. Results: The treatment with PA increased the expression of UPR associated genes significantly and induced ER stress in a 12-hour treatment. Subsequent treatment with S.horneri reduced mRNA expression of ATF4, GRP78, and XBP1s. In addition, the protein levels of phosphate (p)-IRE1α, p-elF2α, and CHOP were also reduced by a treatment with S. horneri.An analysis of sirtuin (SIRT) mRNA expression in the S. horneri and PA-treated HepG2 cells showed that S. horneri increased the levels of SIRT2, SIRT6, and SIRT7, which indicates a possible role in reducing the expression of ER stress-related genes. Conclusion These data indicate thatS. horneri can exert an inhibitory effect on ER stress caused by PA and highlight its potential as an agent for managing various ER stress-related diseases.

Herein, we report a rare case of hemolytic anemia with reticulocytopenia following intravenous immunoglobulin therapy in a young infant treated for Kawasaki disease. A 2-month-old boy presented with fever lasting 3 days, conjunctival injection, strawberry tongue, erythematous edema of the hands, and macular rash, symptoms and signs suggestive of incomplete Kawasaki disease. His fever resolved 8 days after treatment with aspirin and high dose infusion of intravenous immunoglobulin. The hemoglobin and hematocrit decreased from 9.7 g/dL and 27.1% to 7.4 g/dL and 21.3%, respectively. The patient had normocytic hypochromic anemia with anisocytosis, poikilocytosis, immature neutrophils, and nucleated red blood cells. The direct antiglobulin test result was positive, and the reticulocyte count was 1.39%. The patient had an uneventful recovery. However, reticulocytopenia persisted 1 month after discharge.
