The objectives of this study were to investigate the immune responses of broiler chickens fed diets supplemented with different level of chromium methionine (CrMet) in heat stress (HS) condition. Two hundred and eighty eight male broiler chickens (Ross 308) were allocated to four treatment groups (supplementation with 0, 200, 400 or 800 ppb Cr in the form of CrMet) in a completely randomized design. The experiment was conducted at heat stressed condition and all birds were kept under temperature of $33{\pm}2^{\circ}C$. Antibody titers against Newcastle disease virus (NDV) and infectious bronchitis virus (IBV), heterophil to lymphocyte ratios (H/L), and concentration of plasma cortisol (CPC) were measured at 21 and 42 d. At 42 days of age two birds were chosen randomly from each replicate, slaughtered, spleen and bursa of Fabricius were collected, weighed and expressed as a percentage of live body weight. Antibody titers against NDV and IBV at 21 and 42 days of age in broiler fed supplemental CrMet were higher than in broiler chickens fed control diet (p<0.05). CPC level in broiler chickens fed CrMet were significantly (p<0.05) decreased. Increases in lymphocyte counts and consequently a decrease in heterophil to lymphocyte ratios in broiler chickens fed 800 ppb Cr were observed at 21 and 42 d. Supplementation with CrMet had no significant effect on lymphoid organs of broilers. The results suggest that dietary CrMet supplementation at a level of 800 ppb can improve some immune responses of broiler chickens under heat stress conditions.

Intestinal absorption of dietary taurine is one of the regulatory component maintaining taurine homeostasis along with renal reabsorption, bile acid conjugation and secretion, and de nobo synthesis of taurine in mammals. Recent observations of decreased enterocytic levels of taurine in response to trauma, infection and surgical insults, postulate the possibility that intestinal taurine absorption might be impaired in such stressed conditions. The aim of the present study was to evaluate changes in enterocytic taurine transporter activity using the human intestinal colon carcinoma cell line, HT-29, in various stress-induced conditions. Pretreatment of the HT-29 cells with dexamethasone, a stress hormone(0.1,1,10 or 100$\mu$M) for 3 hrs, or with E coli heat-stable enterotoxin(10, 100, or 200nM) for 30 minutes in order to induce the condition of enterotoxigenic infection did not influence taurine uptake as compared to the value found in control cells. In contrast, pretreatment of the cells with cholera toxin(10, 100, 500, or 1000ng/ml)for 3hr or 24hr significantly decreased taurine uptake by HT-29 cells to 40~50% of the value found in untreated control cells. Kinetic studies of the taurine transporter activity were conducted in control and cholera toxin treated HT-29 cells with varying taurine concentrations(2~60$\mu$M) in the uptake medium. Pretreatment of the cells with cholera toxin(100ng/ml) for 3hr did not influence the Vmax, but resulted in a 55% increase in the Michaelis-Menten constant(Km) of the taurine transporter compared to those in control cells. These results suggest that cholera toxin-induced reduction in taurine transporter activity in HT-29 cells is associated with decreased affinity of the taurine transporter without altering the amount of transporter protein. Intestinal taurine absorption appears to be reduced in the condition of water-borne diseases caused by bacteria such as V. cholerae. This might influence the taurine status of infants and young children more readily, an age group in which the prevalence of intestinal infection is high and the role of intestinal absorption is crucial for maintaining the body taurine pool.

This study was carried out to collect information to establish a framework for meal management and nutritional service for prevention of chronic degenerative disease in the industrial workers. We investigated the health concerned life-style, nutrient intakes, anthropometry and biochemical parameters in the male workers in Korea by work condition. Anthropometric parameters of height, weight, waist, hip and triceps skinfold thickness were measured and biochemical parameters including Urine pH, hemoglobin, blood glucose, total cholesterol, GOT, GPT, $\gamma$-GPT and blood pressure were determined for 101 subjects(50 office workers : 33.9yr, 51 laborers : 34.4yr). To assess the nutrient intakes and diet quality of workers, dietary intake was measured by one day 24-hour recall method. Result of anthropometric parameters of height(p<0.01), weight(p<0.05), hip(p<0.05), TSF(p<0.01) were significantly higher in office workers than in laborers. Biochemical parameters were not significantly difference in both of them. Average daily nutrient intakes of both groups was higher than the Korean RDA and report on 2001 National Health & Nutrition Survey. The calcium(p<0.01), iron(p<0.05), vitamin A(p<0.01), vitamin B1(p<0.01) and niacin(p<0.05) intakes in laborers were significantly higher than in office workers. Nutrition adequacy ratio(NAR), mean adequacy ratio(MAR) and index of nutritional quality(INQ) of laborers were higher than those of office workers. This results indicated that the onset possibility of chronic degenerative disease appeared higher in office workers. Therefore, meal menagement and nutritional service for prevention of chronic degenerative disease of industrial works needs to be more variant guidelines.

Eating behaviour disorder during early childhood is a common pediatric problem. Many terminologies have been used interchangeably to describe this condition, hindering implementation of therapy and confusing a common problem. The definition suggests an eating behaviour which has consequences for family harmony and growth. The recent Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition does not cover the entire spectrum seen by pediatricians. Publications are substantive but level of evidence is most of the time low. This purpose of this review is to clarify terminology of eating behaviour problems during early childhood; including benign picky eating, limited diets, sensory food aversion, selective eating, food avoidance emotional disorder, pervasive refusal syndrome, tactile defensiveness, functional dysphagia, neophobia and toddler anorexia. This tool is proposed only to ease the clinical management for child care providers. Diagnostic criteria are set and management tools are suggested. The role of dietary counselling and, where necessary, behavioural therapy is clarified. It is hoped that the condition will make its way into mainstream pediatrics to allow these children, and their families, to receive the help they deserve.

Immunostimulating effects of fucoidan administration to rockfish Sebastes schlegelii at a concentration of 20 g/kg of diet were evaluated under high water temperature condition. The oral administration of fucoidan mixed with feed at a concentration of 20 g/kg of diet for 2 weeks increased the interleukin 1β gene in the intestine and kidney of fish by 5.7 and 6.3 times, respectively. In addition, when the water temperature was gradually increased from 24 to 31.4℃ for 2 weeks, LT₅₀ delayed by 24 h in the fucoidan treated group compared to that in the control group, and mortality also reduced. Streptococcus iniae infection at a concentration of 1.50×10⁰ CFU/fish at 28℃ delayed LT₅₀ by 12 h in the fucoidan-treated group. Furthermore, the overall survival rate was 0% in the control group and 20% in the fucoidan-treated group. This study confirmed the applicability of dietary additives such as fucoidan as an immune activator of rockfish under high temperature condition.

The occurrence of toothache signals the malfunction in oral health, which allows the detection of any abnormal condition in the oral cavity at an early stage to prevent the condition from worsening, and thus can act as a preventive measure. This study has looked into the status of oral health management in relation to toothache through the structured survey administered to 235 college students. Based on the survey results, this study aimed at comparing the toothache occurrence prediction between regression analysis and CART model in order to clarify the relationship between the factors of oral health management habits that contribute to toothache occurrence. According to the result, there was a difference between the present health status and the health status of the past year depending on the presence or non-presence of toothache occurrence (p<0.05). There was a difference in the regularity of meal time depending on the presence non-presence of toothache occurrence from the dietary habits of the research subjects (p<0.05). As for the presence or non-presence of toothache occurrence from the oral hygiene habits of the research subject, there was a difference between the occurrence and nonoccurrence of bleeding during brushing or flossing (p<0.05). According to the results of regression analysis, no factors were signifiant in the relationship with the presence or non-presence of toothache occurrence from the status of life habits and oral hygiene habits. 70% of the researched group was randomly selected as the sample for generating an analytical model and the remaining 30% was used as the sample for generating an evaluation model. According to the results of CART model, the occurrence of toothache was higher in the case of irregular meal time and poor current health condition than the case of average or satisfactory health condition. The above results imply that CART model is very useful technique in predicting toothache occurrence compared to regression analysis, and suggests that CART model could be very useful in predicting other oral diseases including toothache.

The archeological remains usually exist in some excavated ancient soils. The ancients oils are buried in underground with the environmental, biological and social facts for circumstantial evidence at past times. Consequently, it is very important thing to carry out scientific analysis of the ancient soils side by side with archeological study. In this study, we accumulated some basic data for scientific analysis of 5 kinds of ancient soils excavated at Wanggung-ri, Iksan city. So we obtained some characterizations of organic chemical source, ancient parasite egg, and some seeds in the soils. The organic sources showed the content of high organic material as 7~22%, and strong acidic condition as pH 2~6. It is indicated that Wanggung-ri soils have included so many organic materials from the degradation of biological remains. Most of all, we searched a lot of eggs of parasite Trichuris trichiura and so it is possible that this area had been a ancient toilet at that times. The more scientific analysis of the soils will be showed us about the utility of the area, ancient dietary life style, ancient environment and ancient human diseases.

Purpose: This article provides an update and overview of a nursing research program focused on understanding the pathophysiology and management of irritable bowel syndrome (IBS). Methods: This review includes English language papers from the United States, Europe, and Asia (e.g., South Korea) from 1999 to 2013. We addressed IBS as a health problem, emerging etiologies, diagnostic and treatment approaches and the importance of a biopsychosocial model. Results: IBS is a chronic, functional gastrointestinal disorder characterized by recurrent episodes of abdominal pain and alterations in bowel habit (diarrhea, constipation, mixed). It is a condition for which adults, particularly women ages 20-45, seek health care services in both the United States and South Korea. Clinically, nurses play key roles in symptom prevention and management including designing and implementing approaches to enhance the patients' self-management strategies. Multiple mechanisms are believed to participate in the development and maintenance of IBS symptoms including autonomic nervous system dysregulation, intestinal inflammation, intestinal dysbiosis, dietary intolerances, alterations in emotion regulation, heightened visceral pain sensitivity, hypothalamic-pituitary-adrenal dysregulation, and dysmotility. Because IBS tends to occur in families, genetic factors may also contribute to the pathophysiology. Patients with IBS often report a number of co-morbid disorders and/or symptoms including poor sleep. Conclusion: The key to planning effective management strategies is to understand the heterogeneity of this disorder. Interventions for IBS include non-pharmacological strategies such as cognitive behavior therapy, relaxation strategies, and exclusion diets.

Inhibition of intestinal glucose uptake is beneficial in reducing the blood glucose level for diabetes. To search for an effective intestinal glucose uptake inhibitor from natural sources, 70 native edible plants, fruits and vegetables were screened using Caco-2 cells and fluorescent D-glucose analog 2-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl) amino]-2-deoxy-D-glucose (2-NBDG). A compound that was able to inhibit glucose uptake was isolated from methanol extract of Punica granatum L. and called PG-1a. PG-1a appears to be a phthalic acid-diisononyl ester- like compound (PDE) with molecular weight of 418. The inhibitory effect of PG-1a on intestinal glucose uptake was dose-dependent with 89% inhibition at $100\;{\mu}g$/mL. Furthermore, the intestinal glucose uptake inhibitory effect of PG-1a was 1.2-fold higher than phlorizin, a well known glucose uptake inhibitor. This study suggests that PG-1a could play a role in controlling the dietary glucose absorption, and that PG-1a can effectively improve the diabetic condition, and may be used as an optional therapeutic and preventive agent.
