Methods: The mixture of IB and DJ extracts was analyzed for its total flavonoid content (TFC), total polyphenol content (TPC), and radical scavenging activities. Gastric lesions were induced by treating rats with 1 mL of a solution containing 60% ethanol and 150 mM HCl.The rats were then divided into 5 groups: CON (normal control), HEC (treated with 150 mM HCl-60% ethanol and distilled water), IBE (treated with 150 mM HCl-60% ethanol and IB extract at 350 mg/kg body weight [BW]), ID30 (treated with 150 mM HCl-60% ethanol and a mixture of IB and DJ extracts in a 7:3 ratio at 350 mg/kg BW), and DJE (treated with 150 mM HCl-60% ethanol and DJ extract at 350 mg/kg BW). Results: The ID30 group exhibited significantly higher TFC, TPC, and radical scavenging activities than the groups treated with single extracts. This group also showed a notable decrease in the formation of gastric lesions and preservation of gastric wall mucus. In addition, the serum levels of the inflammatory marker tumor necrosis factor (TNF)-α were significantly lower in the ID30 group than in the HEC group. Conclusion The antioxidants present in the ID30 mixture effectively reduced oxidative stress and reactive oxygen species, mitigating gastric mucosal irritation induced by alcohol and acid. Furthermore, the mixture inhibited gastric acid secretion and inflammatory marker expression, such as TNF-α, preventing tissue damage. These findings suggest that the ID30 mixture is a potential preventative treatment for gastritis.

The final version uploaded in NRP and PMC are different. Somehow, the PMC version is not the final version of this publication. The PMC version is the version before final revision. Also the authors found out that there is an error in Table 1. These errors did not influence the subsequent analyses/statistics at all. Thus, changes for these errors do not impact the conclusions of the paper

PURPOSE: This review article provides an overview of the trends of research papers on the health benefits of kimchi and kimchi lactic acid bacteria published from 1995 to 2017. METHODS: All publications from 1995 to 2017 regarding kimchi and kimchi lactic acid bacteria were collected, reviewed, and classified. This review article covers the publications of the health benefits of kimchi and kimchi lactic acid bacteria on experimental, clinical trials, and epidemiology studies. RESULTS: The number of publications on kimchi over the period were 590: 385 publications in Korean and 205 publications in English. The number of publications on the health benefits of kimchi and kimchi lactic acid bacteria were 95 in Korean and 54 in English. The number of publications on kimchi and kimchi lactic acid bacteria were 84 and 38, respectively, in the experimental models. Ten research papers on kimchi in clinical trials and 7 publications in epidemiology were found. Kimchi or kimchi lactic acid bacteria had protective effects against oxidative stress, mutagenicity, toxicity, cancer, dyslipidemia, hypertension, immunity, and inflammation in in vitro, cellular, and in vivo animal models. Moreover, kimchi had effects on the serum lipids, intestinal microbiota, iron status, obesity, and metabolic parameters in human clinical trials. In epidemiology, kimchi had effects on hypertension, asthma, atopic dermatitis, rhinitis, cholesterol levels, and free radicals. CONCLUSION: This review focused on the publications regarding the health benefits of kimchi and kimchi lactic acid bacteria, suggesting the future directions of studies about kimchi and kimchi lactic acid bacteria by producing a database for an evaluation of the health benefits of kimchi.

PURPOSE: The aim of this study was to describe our treatment experiences with patients who had acute abdomen (AA) with common bile duct (CBD) dilatation. METHODS: The treatment outcomes in children with AA and CBD dilatation were retrospectively reviewed. According to the shape of the intrahepatic bile ducts on ultrasonography (US), the origin of the pain was estimated as choledochal cyst (CC) complication or choledocholithiasis in normal CBD. Patients with complicated CC underwent surgery, and patients with choledocholithiasis in a normal appearing CBD underwent symptomatic treatment initially. RESULTS: Of the 34 patients, 30 (88.2%) were female. The mean age of the patients was 6.4±4.9 (range, 0.8–17) years. Seventeen (50.0%) patients had CBD stones and 17 (50.0%) did not. Surgical treatment was performed in 20 (58.8%) patients, 2 of whom underwent preoperative stone removal with endoscopic retrograde cholangiopancreatography and an operation. Conservative treatment was applied in 12 (35.3%) patients (8 with and 4 without stones), 1 of whom developed symptom relapse and underwent an operation. Among the 8 patients with CBD stones, 4 (4/17, 23.5%) had complete resolution of the stones and recovery of the CBD diameter after conservative treatment. US findings of patients with stone showed a fusiform or cylindrical shape of the CBD in 14 (82.4%) patients. CONCLUSION: The presence of stones in the distal CBD and the US features of CBD dilatation may be helpful to diagnose and treat the causes of biliary dilatation. Conservative treatment can be considered as initial therapy in patients with uncomplicated CBD dilatation with stone.

BACKGROUND/OBJECTIVES: Ginger, a root vegetable, is known to have antioxidant and antiobesity effects. Preparation, such as by steaming, can affect the chemical composition of prepared root vegetables or herbs and can change their functional activities. In the present study, we investigated the protective effects of steamed ginger against oxidative stress and steatosis in C57BL/6J mice fed a high-fat diet. MATERIALS/METHODS: The levels of polyphenols and flavonoids in two different extracts of steamed ginger, i.e., water extract (SGW) and ethanolic extract (SGE); as well, their antioxidant activities were examined. Forty male C57BL/6J mice were fed a normal diet (ND, n = 10), high-fat diet (HFD, 60% fat, w/w, n = 10), HFD supplemented with 200 mg/kg of SGE or garcinia (GAR) by weight (SGED or GARD, respectively, n = 10) for 12 weeks. Serum chemistry was examined, and the expressions of genes involved in lipid metabolism were determined in the liver. Histological analysis was performed to identify lipid accumulations in epididymal fat pads and liver. RESULTS: The SGE had higher contents of polyphenols and flavonoids and higher DPPH and ABTS⁺ free radical scavenging activities compared to those of SGW. Treatment with SGE or GAR significantly decreased the HFD-induced weight gain. Both SGE and GAR significantly reduced the high serum total cholesterol (TC), triglyceride (TG) and low-density lipoprotein levels induced by HFD. Compared to ND, HFD significantly increased hepatic TC and TG levels. SGE or GAR supplementation significantly decreased the increase of hepatic lipids by HFD. Interestingly, SGE had a more significant effect in reducing hepatic TC and TG levels than GAR. Furthermore, hepatic genes involved in lipogenesis and lipolysis were altered in both the SGED and GARD groups. CONCLUSIONS: The present study indicates that steamed ginger supplementation can decrease plasma TC and TG and can inhibit liver steatosis by regulating the expressions of hepatic genes.

OBJECTIVE: The aims of this study was to present an association between the presence of psychotic symptoms and cortical thicknesses/subcortical volumes in patients with Alzheimer's disease (AD). METHODS: Fourteen AD patients with psychotic symptoms and 41 without psychotic symptoms underwent 3T MRI scanning. After adjusting the effects of confounding variables, the cortical thicknesses were compared between the AD patients with and without psychotic symptoms in multiple regions, across the continuous cortical surface. In addition, the subcortical volumes were compared with a structure-by-structure manner. RESULTS: AD patients with psychotic symptoms were characterized by significant smaller cortical thickness of left pars opercularis (F=4.67, p=0.02) and left lateral occipital gyrus (F=6.05, p=0.04) rather than those without psychotic symptoms, after adjusting the effects of age and scores on the Stroop test, non-psychotic items of Neuropsychiatry Inventory and Clinical Dementia Rating, triglyceride level and total intracranial volume. However, there were no significant differences in the subcortical volume between the two groups. CONCLUSION: These results suggest that AD psychosis may reflect more severe deterioration of neuropathologic change in specific brain region.

BACKGROUND/OBJECTIVES: Although Korean fermented foods contain large amounts of salt, which is known to exacerbate health problems, these foods still have beneficial effects such as anti-hypertension, anti-cancer, and anti-colitis properties. We hypothesized that ganjang may have different effects on blood pressure compared to same concentrations of salt. MATERIALS/METHODS: Sprague-Dawley rats were divided into control (CT), NaCl (NC), and ganjang (GJ) groups and orally administered with 8% NaCl concentration for 9 weeks. The systolic blood pressure (SBP), serum chemistry, Na⁺ and K⁺ concentrations and renal gene expressions were measured. RESULTS: The SBP was significantly increased in the NC group compared to the GJ and CT groups. In addition, the Na+ concentration in urine was higher in the GJ and NC groups than the CT group, but the urine volume was increased in the GJ group compared to the other groups. The serum renin levels were decreased in the GJ group compared to the CT group, while the serum aldosterone level was decreased in the GJ group relative to the NC group. The mRNA expression of the renin, angiotensin II type I receptor, and mineralocorticoid receptor were significantly lower in the GJ group compared to other groups. Furthermore, GJ group showed the lowest levels of genes for Na⁺ transporter in kidney cortex such as Na⁺/K⁺ ATPaseα1 (NKAα1), Na⁺/H⁺ exchanger 3 (NHE3), Na⁺/HCO₃⁻ co-exchanger (NBC), and carbonic anhydrases II (CAII). CONCLUSIONS: The decreased SBP in the GJ could be due to decreased renin and aldosterone levels in serum and increased urinary volume and excretion of Na⁺ with its transporter gene alteration. Therefore, ganjang may have antihypertensive effect despite its high contents of salt.

PURPOSE: The objective of the present study was to determine whether fermentation can increase the protective effects of blueberry liquid in a high-fat diet-induced obese mice model. METHODS: Male C57BL/6J mice were fed a high-fat diet (HD, 60% fat, w/w,), HD supplemented with 10 ml/kg BW/day of blueberry liquid (BHD, blueberry high-fat diet), or HD supplemented with 10 ml/kg BW/day of fermented blueberry liquid (FBHD, fermented blueberry high-fat diet) for 10 weeks. RESULTS: There were significant decreases in the body, epididymal adipose tissue, and liver weights of blueberry-fed groups compared to HD, whereas there were no significant differences in food intake among the groups. Furthermore, blueberry liquid groups, especially fermented blueberry liquid, significantly attenuated the contents of hepatic triglycerides and total cholesterol induced by HD. Serum LDL-cholesterol was significantly lower in the BHD and FBHD-fed groups, whereas FBHD significantly increased the serum HDL-cholesterol level compared to the control. Concentrations of aspartate transaminase, alanine transaminase, and leptins in serum were also reduced by blueberry liquid supplementation. The mRNA expression of hepatic acetyl CoA carboxylase was significantly reduced in both the BHD and FBHD groups compared to HD. Furthermore, FBHD altered the mRNA expression level of hepatic lipolysis genes. CONCLUSION: In conclusion, these results suggest that blueberry, especially fermented blueberry liquid, may improve obesity-related abnormalities.

OBJECTIVES: In this study, the authors evaluated the correlation between levels of serum lipid, homocysteine, and folate with volumes of hippocampus, amygdala, corpus callosum, and in patients with amnestic mild cognitive impairment (aMCI) or Alzheimer's disease (AD) type. METHODS: The study recruited patients who visited the dementia clinic of Haeundae Paik Hospital in Korea between March 2010 and June 2014. Among those, patients who had taken the neurocognitive test, brain magnetic resonance imaing, tests for serum lipid, homocysteine, folate, and apolipoprotein E (APOE) genotyping and diagnosed with aMCI or AD were included for analysis. Bilateral hippocampus, entorhinal cortex, amygdala and corpus callosum were selected for region of interest (ROI). The cross-sectional relationships between serum lipid, homocysteine, folate and ROI were assessed by partial correlation analysis and multiple linear regression analysis. RESULTS: In patients with aMCI, old age (> 80) and APOE epsilon4 carrier were associated with AD [odds ration (OR) : 12.80 ; 95% confidence interval (CI) : 2.25-72.98 and OR : 4.48 ; 95% CI : 1.58-12.67, respectively]. In patients with aMCI or AD, volumes and thickness of ROI were inversely correlated with levels of serum lipid and homocysteine. In multiple linear regression analyses, higher total cholesterol level was related to lower left, right hippocampus volume and left amygdala volume ; higher low-density lipoprotein cholesterol was related to lower right entorhinal cortex thickness ; higher homocysteine level was related to lower corpus callosum volume. CONCLUSIONS: Higher serum lipid and homocysteine levels are associated with decreased volume of hippocampus, amygdala, corpus callosum and entorhinal cortex thickness in patients with aMCI or AD. These findings suggest that serum lipid and homocysteine levels are associated with AD as a modifiable risk factor.

PURPOSE: Many studies showed that the asthmatic children mostly have psychosocial problem such as depression or anxiety. The object of this study is to help the asthmatic children and their family by knowing what is their mothers' biggest concern about their asthmatic children. METHODS: We made up a questionnaire with asked the mothers by telephone. If they though asthma had a certain effect on their asthmatic children's activity, depression, anxiety, positiveness, scholastic achievement, friendship, pleasure, concentration, anger, growth and development. We asked the mothers whose children had visited the pediatric department in st. colomban's hospital from 1990 to 1996 and had been diagnosed and treated as asthma, and whose asthmatic children were between 7 and 21. RESULTS: More than half of the mothers who got a phone-call said that their children had problems in house life, school life, social life due to asthma and frequent asthmatic attack made their children less concentrated, inactive, less scholastic achieved, but there were few who said that asthma seemed to have an effect on their children's friendship, depression, pleasure. CONCLUSIONS: In the psychological aspect, the mothers may concern more if their children cannot keep up with the competitive social tendency closely related to concentration and scholastic achievement than if their children have some emotional disorder or behavial disorder such as depression and anxiety
