목 적 : 영양과잉과 활동량의 감소로 비만한 소아가 급속히 증가하고있다. 성인에서는 비만에 의하여 인슐린 저항성과 고인슐린혈증, 당 및 지질대사 이상, 고혈압, 심혈관질환 등이 발생하며, 남녀간에 차이가 있는 것으로 알려져 있다. 소아 청소년 시기에 비만이 인슐린 저항성 및 지질대사 이상에 미치는 영향을 알아보고자 본 연구를 시행하였다. 방 법 : 1999년부터 2001년까지 비만을 주소로 내원한 비만아 중 90 백분위수 이상인 35명의 비만아[나이 : $10.6{\pm}2.8$년; 남(n=20), 여(n=15)]에 대하여 체중과 키를 계측하였고, 공복시 혈중 콜레스테롤, 중성지방, 고밀도 콜레스테롤, 저밀도 콜레스테롤, 혈당과 혈중 인슐린 농도를 측정하였다. 인슐린 저항성 지표로 공복 인슐린/혈당비(FIGR), HOMA-IR[$(glucose(mmol/L){\times}insulin({\mu}U/mL)$/22.5]를 이용하였다. 결 과 : 1) 체질량지수(BMI) : 전체 비만아의 BMI는 $27.1{\pm}5.4kg/m^2$(범위 20.6-44.0)로, 5명이 90-95 백분위수이었고, 30명이 95 백분위수 이상의 고도 비만을 보였으며, 남녀간에 차이는 없었다. 남녀 모두에서 연령과 상관관계가 보였다. 2) 공복시 인슐린 농도 : 인슐린 농도는 $20.7{\pm}10.6{\mu}U/mL$(범위 4.8-53.0)로, 남녀간에 차이는 없었다. 고인슐린혈증은 여아에 비하여 남아에서 유의하게 빈도가 높았다(27% vs 75%). 연령과 상관관계가 없었다. 3) 혈중 지질대사 : 혈중 중성지방이 150 mg/dL 이상인 비만아는 13명(37%), 고밀도 콜레스테롤이 40mg/dL 이하인 군은 2명(5.7%)이었다. 4) HOMA-IR과 인슐린 농도와의 관계 : 인슐린 저항성의 지표인 HOMA-IR은 인슐린 농도와 인슐린/혈당비에 대해 각각 양의 상관관계를 보였다(인슐린 : r=0.960, P<0.01; 인슐린/혈당비 : r=0.842, P<0.01). 5) BMI와 HOMA-IR, 인슐린 농도, 지질대사와의 관계 : BMI는 인슐린 농도, HOMA-IR, FIGR과 유의한 양의 상관관계를 보였으며(인슐린 r=0.629; HOMA-IR r=0.622; FIGR r=0.583; P<0.01), 남자에서 여자에 비하여 더 강한 상관관계를 보였다. 남녀 모두에서 BMI는 총콜레스테롤, 중성지방, 고밀도 콜레스테롤 및 저밀도 콜레스테롤과 상관관계가 관찰되지 않았다. 6) 공복시 혈중 인슐린 농도와 혈중 지질농도 : 중성지방은 남자에서 인슐린 농도와 유의한 양의 상관관계가 있었으나(r=0.544, P=0.013), 여아에서는 상관관계가 없었으며, 고밀도 콜레스테롤도 남자에서만 인슐린 농도와 약한 상관관계가 있었다(남자 : r=-0.431, P=0.058). 결 론 : 소아와 청소년에서는 지질대사 이상을 반영하는데 있어 BMI보다 인슐린 농도가 더 연관성이 크므로, 공복시 인슐린 농도를 측정하는 것이 비만에 의한 대사 이상을 평가하는데 큰 도움이 될 것으로 사료되며, 여자에 비하여 남자에서는 심혈관질환 및 대사 이상을 강화시킬 수 있는 고인슐린혈증의 빈도가 높기 때문에 더욱 더 적극적인 치료가 요구될 것으로 사료된다.

This study aims at grasping the relativity between laborers' yangseng level and stress so as to present the groundwork for preventive oriental medicine approach in industrial health. The researcher prepared the questionnaire on general character, health-related yangseng level and chose 632 people to execute Autonomic balance test through heartbeat change. The collected material was analyzed by SPSS and tested by T-test, ANOVA. The general yangseng level average is 3.27, morality yangseng 3.91, sleep yangseng 3.39, mind yangseng 3.32, sex life yangseng 3.29, exercise yangseng 3.14, activities and rest yangseng 3.07, diet yangseng 2.95, seasonal yangseng 2.84. The highest is morality yangseng and seasonal yangseng is the lowest. In the aspect of yangseng level : Having a spouse, Non-smoking, Non-drinking, Regular exercising, Sufficient sleeping have higher yanseng levels. In Autonomic balance test, age from 35 to 40 has the highest autonomic activity and job period from 5 years to 10 years has the highest stress resistance. Non-smokers have high autonomic activity and stress resistance. Further, have low autonomic balance, stress index and fatigue strength. In the case of regular exercising person, he/she has high autonomic activity and stress resistance with low stress index. Regarding sleeping time, autonomic balance is the highest when he/she sleeps less than 6 hours. Stress resistance is the highest when he/she sleeps 7 hours and stress index is the highest when he/she sleeps 6 hours. After comparing the relativity between yangseng level autonomic balance test, only exercise yangseng has plus factor on autonomic activity and stress resistance and minus factor on stress ind ex and fatigue strength. Yangseng level has been affected by individual character and daily habits. Also stress is more influenced by daily habits than by individual character. We can find the relativity of exercise yangseng between yangseng and stress which suggests that we need to take measures to win over stress in individual health in the near future.

Background: Studies of effects of IL-1 polymorphisms, CYP2C19 genotype together with antibiotic resistance for H. pylori eradication are rare worldwide. The present study was designed to evaluate efficacy of 10-day sequential therapy (SQT) and 14-day standard triple therapy (STT) with four- times-daily dosing of amoxicillin for H. pylori eradication related to these important host and bacterial factors in Thailand. Materials and Methods: This prospective randomized study was performed during March 2015 to January 2016. H. pylori infected gastritis patients were randomized to receive 10-day sequential therapy and 14-day standard triple therapy. CYP2C19 genotyping, IL1 polymorphism (IL-1B and IL-1RN genotypes) and antibiotic susceptibility tests were performed in all patients. 13C-UBT was conducted to confirm H. pylori eradication at least 4 weeks after treatment. Results: A total of 100 patients (33 males and 67 females, mean age=51.1 years) were enrolled. Eradication rate by PP analysis was 97.9% (47/48) with the 10-day SQT regimen and 87.8% (43/49) with 14-day STT regimen (97.9% vs 87.8%; p-value=0.053). Antibiotic susceptibility testing demonstrated 45% resistance to metronidazole, 14.8% to clarithromycin, and 24.1% to levofloxacin. CYP2C19 genotyping revealed 44.9% RM, 49% IM and 6.1% PM. IL-1B and IL-1RN genotypes were demonstrated as 21.4% for CC, 48.1% for TC, 36.8% for TT, 72.7% for 1/1, and 21.2% for 1/2 genotypes, respectively. The 10-day SQT regimen provided 100% eradication in patients with clarithromycin or dual clarithromycin and levofloxacin H. pylori resistant strains. Moreover, the 10-day SQT regimen resulted in a 100% eradication rate in all patients with CYP2C19 genotype RM and almost type of IL-1B (TC and TT) and IL1-RN genotypes ( 1/2 and other). Conclusions: Treatment with 10-day sequential therapy is highly effective for H. pylori eradication regardless of the effects of clarithromycin resistance, dual clarithromycin and levofloxacin resistance, CYP2C19 genotype, IL-1B and IL1-RN genetic polymorphisms and can be used as effective first line therapy in Thailand.

A breeding program in progress at Suweon Livestock Experiment Station, RDA, involves the hybridization of italian ryegrass (Lm) and several leading forage grasses in an effort to combine the nutritive, productivity and palatability qualities of Lm with the adaptive and cold resistance qual; .les of several leading grasses. In order to study the fate of the hybridization between remotely related species, immatured hybrid embryos were cultured on media. The emasculated plants of Lm were Sikem and Tetrone. Reweille, 2n=14, of perennial ryegrass (Lp.), Forager, 2n=42, of tall fescue(Fa), First, 2n=14,of meadow fescue(Fp), Potomac, 2n=28, of orchardgrass(Dg), and Richmond, 2n=42, of timothy(Ph.p) were used as pollinators. Embryos were isolated on 4, 8, 12, 16, and 20 days after pollination and cultured them on modified Murashige and Skoog media. Calluses and plantlets have been obtained after 8 days old embryos crossing between $Lm{\times}Fa$, after 12 days embryos crossing between $Lm{\times}Lp$, Dg, and Ph.p, and after 16 days embryos crossing between $Lm{\times}Fp$. Both callus and shoot formation occurred on 6 % or less of the plated embryos of $Lm{\times}Fp$, Dg, and Ph.p. Embryoderived callus forming shoots have been obtained from 4 days old embryo crossing between $Lm{\times}Dg$ which has not successfully been done anywhere as far as we know. It means that hybrid plants of species without crossability can be obtained through the use of immatured embryo culture. Some of plated embryos developed directly shoots from embryos and the others shoot-forming callus. Cross between related species showed a high frequency of directly shoot formation from plated embryos and cross between remotely related species a high frequency of callus formation.

Shigella is one of the most prevalent pathogens for the diarrhoeal diseases in the developing countries. One hundered and six strains of shigella were isolated from January 1980 to August 1981 at the dept. of clinical pathology, Han Yang Medical Center. Subgroups of these strains were identified as one strain of S. dysenteriae, 98 strains of S. flexneri and 7 strains of S. sonnei. None of S. boydii was observed. Sex ratio, male to female was 48 to 58. Age distribution disclosed 6 cases under one year, 11 cases one to under 2 years and 21 cases(19.8%) two to under 3 years. Subtotal of 0 to 9 years showed 64 cases(60.4%). Susceptibility for antibiotics of these strains revealed dibekacin 100%, sisomicin 100%, amikacin 98.1%, cefazolin 97.2%, tobramycin 97.1%, gentamicin 95.2%, colistin 93.0%, minocycline 89.6%, kanamycin 83.0%, carbenicillin 18.9%, streptomycin 18.9%, tmp-smz 8.6%, ampicillin 2.8% and chloramphenicol 1.9%. Patterns of resistance to sulfa, streptomycin, chloramphenical and tetracycline have already started at the early part of 1960 decade. Although ampicillin was highly sensitive to shigella at the end of 1960 to the early part of 1970 decade, this study has disclosed high resistance to the strains. New antibiotics such as amikacin, cefazolin, dibekacin, gentamicin, and tobramycin have revealed highly sensitive to these strains, however, multiresistance for those antibiotics will be shown to be prevalent in this country within several years, where it is probably related to the unrestricted sale and use of antibiotics in man.

Here in this study, we investigated the lifespan-extending effect and underlying mechanism of methanolic extract of Moringa olelifa leaves (MML) using Caenorhabditis elegans (C. elegans) model system. To define the longevity properties of MML we conducted lifespan assay and MML showed significant increase in lifespan under normal culture condition. In addition, MML elevated stress tolerance of C. elegans to endure against thermal, oxidative and osmotic stress conditions. Our data also revealed that increased activities of antioxidant enzymes and expressions of stress resistance proteins were attributed to MML-mediated enhanced stress resistance. We further investigated the involvement of MML on the aging-related factors such as growth, food intake, fertility, and motility. Interestingly, MML significantly reduced growth and egg-laying, suggesting these factors were closely linked with MML-mediated longevity. We also observed the movement of aged worms to estimate the effects of MML on the health span. Herein, MML efficiently elevated motility of aged worms, indicating MML may affect health span as well as lifespan. Our genetic analysis using knockout mutants showed that lifespan-extension activity of MML was interconnected with several genes such as skn-1, sir-2.1, daf-2, age-1 and daf-16. Based on these results, we could conclude that MML prolongs the lifespan of worms via activation of SKN-1 and SIR-2.1 and inhibition of insulin/IGF pathway, followed by DAF-16 activation.

Background: Spontaneous bacterial peritonitis (SBP) is a serious infectious complication in patients with liver cirrhosis. However, information about prognosis of SBP in hepatocellular carcinoma (HCC) patients is limited. We investigated the clinical course of SBP in HCC patients. Methods: This study enrolled patients diagnosed with SBP between 2005 and 2017. Medical records of patients were reviewed and clinical course was compared between the non-HCC and HCC groups. Results: In total, 123 SBP cases including 49 HCC cases were enrolled. Men were predominant (48/74, 64.9% vs. 34/49, 69.4%; P = 0.697); median age was 58 years in both non-HCC and HCC groups (P = 0.887). The most common etiology was alcohol (32/74, 43.2%) in non-HCC group and hepatitis B (30/49, 61.2%) in HCC group (P = 0.009). Antibiotic resistance rate was higher in non-HCC than in HCC group (29.7% vs. 12.2%; P = 0.028); in-hospital mortality did not differ between the groups (25/74, 33.8% vs. 13/49, 26.5%; P = 0.431). Development rate of hepatorenal syndrome did not differ between non-HCC and HCC group (14/74, 18.9% vs. 10/49, 20.4%; P = 1.000), but hepatic encephalopathy was less common in HCC group (26/74, 35.2% vs. 9/49, 18.3%; P = 0.008). The most important predictor of in-hospital mortality in patients with HCC was white blood cell count above $11,570cells/mm^3$ (odds ratio, 6.629; 95% confidence interval, 1.652-26.590; P = 0.008). Conclusion: Prognosis of SBP in HCC patients is relatively less severe. This result may be related with reduced antibiotics resistance and lower development rates of other complications, such as hepatic encephalopathy. Degree of systemic inflammation may be the most important factor for in-hospital mortality.

Objective: The aim of this study was to compare serum fetuin-A levels and oxidative stress markers, as indicators of insulin resistance, in women with polycystic ovary syndrome (PCOS) and in healthy controls. Methods: This prospective case-control study included 46 patients with PCOS and 48 age- and body mass index-matched control women. Levels of serum hormones, fetuin-A, and oxidative stress markers were measured in blood samples taken during the early follicular period from each participant. Results: Follicle-stimulating hormone (FSH), luteinising hormone (LH), total testosterone levels, and the LH/FSH ratio were found to be significantly higher in women with PCOS than in controls. Serum total antioxidant status, total oxidant status, and oxidative stress index parameters all indicated significantly higher levels of oxidative stress in PCOS patients than in controls. Serum fetuin-A levels, which were analyzed as an indicator of insulin resistance, were higher in the PCOS group than in the control group ($210.26{\pm}65.06{\mu}g/mL$ and $182.68{\pm}51.20{\mu}g/mL$, respectively; p= 0.024). Conclusion: The data obtained from the present study suggest that higher levels of both serum fetuin-A and oxidative stress markers might be related with PCOS.

Vitamin D is an essential component of bone and mineral metabolism; its deficiency causes growth retardation and skeletal deformities in children and osteomalacia and osteoporosis in adults. Hypovitaminosis D (vitamin D insufficiency or deficiency) is observed not only in adults but also in infants, children, and adolescents. Previous studies suggest that sufficient serum vitamin D levels should be maintained in order to enhance normal calcification of the growth plate and bone mineralization. Moreover, emerging evidence supports an association between 25-hydroxyvitamin D (25[OH]D) levels and immune function, respiratory diseases, obesity, metabolic syndrome, insulin resistance, infection, allergy, cancers, and cardiovascular diseases in pediatric and adolescent populations. The risk factors for vitamin D insufficiency or deficiency in the pediatric population are season (winter), insufficient time spent outdoors, ethnicity (non-white), older age, more advanced stage of puberty, obesity, low milk consumption, low socioeconomic status, and female gender. It is recommended that all infants, children, and adolescents have a minimum daily intake of 400 IU ($10{\mu}g$) of vitamin D. Since the vitamin D status of the newborn is highly related to maternal vitamin D levels, optimal vitamin D levels in the mother during pregnancy should be maintained. In conclusion, given the important role of vitamin D in childhood health, more time spent in outdoor activity (for sunlight exposure) and vitamin D supplementation may be necessary for optimal health in infants, children, and adolescents.
