The effect of meal service for home-staying, urban elderly with low income on their mineral status and prevalence of clinical symptoms was evaluated. One hundred. One hundred and eighty three subjects were assigned to meal-served(served) and non-served(non-served)groups. A meal containing approximately one half of the RDA for energy, protein, calcium and iron was served as lunch every day to served group at a welfare center. Dietary, biochemical and clinical data were collected before and after 6 months of meal service and the changes of parameters were analyzed with paired t-test. served female showed significantly increased intake of calcium. The mean hemoglobin, serum iron, TIBC and serum copper of female were significantly increase with meal service. The proportion of anemic female compared to reference data on hemoglobin, hematocrit and serum iron were 45.5$\%$, 29.1$\%$ and 16.4$\%$ respectively, but were lowered to 18.2$\%$, 7.3$\%$, and 5.5$\%$ after 6 months of meal service. served male showed significant increase in MCHC, serum copper, and urinary Na. The urinary Ca/Creatinine, which is often used as an index of bone resorption, was decreased significantly in served group. The decrease in the proportion of served women suffering from edema of ankle and diarrhea was most apparent and less women reported feeling clinical symptoms of dizziness, constipation, difficulty in hearing, and coughing after meal service. The symptoms of benumbness of hands and feet and coughing was lowered most among men after meal service. Clinical symptoms of non-served elderly did not show improvement in feeling clinical symptoms except slightly decreased frequency in coughing of female and buzzing sound in the ears and diarrhea of male.

Purpose: This study aimed to identify 'objective' differential factors for normal frequent loose stool (NFLS) and diarrheal illness with dehydration and nutritional deficiency (DIDN) among infants with chronic frequent loose stool (CFLS). Methods: Data were analyzed from infants under 2 years of age with CFLS who had been transferred from general pediatricians. These 46 patients were divided into 2 groups (NFLS versus DIDN). Nocturnal stool was defined as evacuation between 10 pm and 6 am. Maximal stool amount/day (measured using the mother's hand) was specified as the highest score during the period of CFLS obtained by adding up each evacuation's score (range, 0-2 points). Results: There were 36 cases of NFLS and 10 of DIDN. A failure to gain weight ($P$=0.0001), fever ($P$=0.0079), colic/abdominal pain ($P$=0.0014), gross blood in stool (except allergic proctocolitis) ($P$=0.0113), nocturnal stool ($P$=0.0001), and the score of stool amount ($P$=0.0001) were found to significantly differentiate the groups. A failure to gain weight was observed in 39% of even NFLS. The frequency, mucus content, and microbiological findings of stools, as well as diaper dermatitis were not found to significantly differentiate the groups. Conclusion: NFLS was more common than DIDN in infants with CFLS. The most 'objective' differential factors were nocturnal stool and the score of stool amount (${\geq}7$ points/day).

This thesis aimed to determine the effecting factors(eating pattern, working condition, stress, health care) that help maintain the health of the cosmetologists' digestive system and the diseases involved (acid reflux, indigestion, gastritis, constipation & diarrhea). The research methods included survey and statistical analysis. The survey was conducted on 242 cosmetologists from August 30 to October 30 2014. The data analysis included frequency, cross table, ${\chi}^2$-test, and regression with SPSS(V. 14). The results were as follows ; (1) The cosmetologists' health of digestive system and eating pattern are related. Regular and enough meal times cause less digestive disease. Acid reflux, indigestion, gastritis, constipation and diarrhea are differently related with the type of usual eating pattern, especially, instant food is not good for digestive health. (2) The cosmetologists' health of digestive system and working condition are related. Longer daily working hours and exposure time to chemical odors are more likely to be associated with digestive diseases; whereas, longer time of standing and talking with colleagues are less likely to be associated with digestive diseases. (3) The cosmetologists' health of digestive system and stress are related. Headache, boredom, conflict of pay and compensation, and insomnia are not good for digestive health. (4) The cosmetologists' health of digestive system and health care are related. Periodical medical examination and usual body stretching are correlated with digestive diseases; whereas, people who do regular exercise and bowel movement are less likely to have digestive diseases.

Enterotoxigenic E. coli is one of causative agents of the infantile diarrhea and traveler's diarrhea. A modified infant mouse assay(IMA) was developed for the detection of heat stable enterotoxin (ST) of E. coli isolated from diarrheal and control infants and assay system was established with using enterotoxin producing reference strains. The supernatant of the 24 hour-shaking culture of E. coli in Casamino Acid Yeast Extract Salt Broth(CYES-2) was ingested orally into the 2-4 day old ICR mice. After the mice were kept at $25^{\circ}C$ for 4 hours, they were sacrificed and the gut weight body weight ratio(GW/BW) was taken as the index of fluid accumulation induced by heat stable enterotoxin of E. coli. The results obtained were as follows; 1. The GW/BW responses of IMA tested with enterotoxin reference strains of E. coli(E. coli O148H28:$ST^+LT^+$, E. coli $O78H^-:ST^+LT^+$, E. coli O15H11:$ST^-LT^+$, E. coli O1H7:$ST^-LT^-$) appeared ta be ST dose-dependent, and not LT-dependent. From the dose-response curve, $25{\mu}l$ of culture supernatant was determined as test amount of the IMA. 2. Frequency distribution of IMA result from 643 strain of E. coli showed normal distribution at low GW/BW ratio and dispersed pattern at high GW/BW ratio. The GW/BW ratios of $0.056{\pm}0.004(mean{\pm}SD)$ of normal distribution which distributed from 0.044 to 0.068(P<0.01) was considered as ST negative. Thus the GW/BW ratio above 0.069 could be regarded as ST positive.

Hematopoietic stem cell tranntation is being widely used in an attempt to treat many hematological diseases such as leukemia, anemia, and lymphoma. To evaluate the success of hematopoietic stem cell transplantation, it is very important to determine how rapidly engraftment occurs. Therefore, this retrospective study was conducted to determine which factors affected the term of engraftment during hematopoietic stem cell transplantation, while focusing on the oral intake status. To accomplish this, 416 patients who underwent transplant operations at St. Mary's hospital from May 2006 to April 2008 were evaluated. The long-term engraftment group was characterized as having longer fasting days and more frequent vomiting, diarrhea, and oral mucositis incidences than the short-term engraftment group. In addition, the inhibitors of oral intake such as vomiting, diarrhea, and oral mucositis developed frequently between the pre-transplantation and 2 weeks after transplantation. A significantly negative correlation was observed between the oral intake volume and the duration of the oral intake inhibitors. A multiple regression analysis revealed that the frequency of vomiting and oral mucositis during hematopoietic stem cell transplantation, the length of hospitalization, and the hematocrit level in the 2 weeks after hematopoietic stem cell transplantation were significant predictors of engraftment. The results of this study could be used to establish a guideline for nutritional assessment, nutritional goals, and nutritional support for patients during hematopoietic stem cell transplantation.

Purpose: The purpose of study was to explore the frequency of irritable bowel syndrome(IBS) among female university students and identify self-esteem, depression, and physical health. Method: The secondary analysis was performed. A total 401 university female students were recruited from 1 university in Korea. IBS was diagnosed based on the Rome III criteria. The questionnaires included Rosenberg's self-esteem scale, Center for Epidemiological Studies-Depression(CESD) scale, and physical health questionnaire developed by Lee. The collected data was analyzed with SPSS Win 15.0 statistics program using frequencies, percentages, ANOVA, and the Pearson's correlations of the variables. Result: The frequency of IBS was 26.7% in students. All women had mixed constipation and diarrhea subtype of IBS. Compared to the women without IBS, those with IBS reported significantly lower scores on self-esteem and higher scores of CESD and on the physical health questionnaire. Conclusion: Nursing interventions targeting female students with IBS should be developed in order to reduce the depression and physical health problem and improve self-esteem.

Diarrhea is a major public health concern associated with pathogenic Escherichia coli infections. Food-borne pathogenic E. coli can lead to large diarrheal outbreaks and hence, there is a need to estimate the frequency of pathogenic E. coli load in the various types of meat available in markets. In the present study, we classified and characterized diarrheagenic E. coli isolates collected from 399 raw meat samples from retail sources in Korea. Shiga toxin-producing E. coli (STEC) were detected in 11 (9.7%) samples, including nine strains (8.0%) in beef and two strains (1.8%) in chicken. The frequency of the detected virulence markers were as follows: astA, 28.3%; escV,18.6%; eaeA,17.7%; ent, 7.0%; EHEC-hly, 4.4%; stx1, 3.5%; and stx2, 3.5%. We did not observe any typical EPEC, EIEC, or ETEC virulence determinants in any of the samples. The STEC serotype O26 was detected in one sample, but no other serogroups (O91, O103, O128, O157, O145, O111, and O121) were found. Further research is needed to better understand the virulence mechanism of STEC serotypes, their ecology, and prevalence in animals, food, and the environment. These results will help improve risk assessment and predict the sources of food poisoning outbreaks.

The crude ethanol extract of leaves of Sonneratia caseolaris Linn. (Sonneratiaceae) was screened for its antinociceptive and antidiarrhoeal activities. The extract produced significant writhing inhibition in acetic acid induced writhing in mice at dose of 250 and 500 mg/kg body weight (P<0.01) comparable to the standard drug diclofenac sodium at the dose of 25 mg/kg of body weight. When tested for its antidiarrhoeal effects on castor oil induced diarrhea in mice, it increased mean latent period and decreased the frequency of defecation significantly at the dose of 500 mg/kg body weight (P < 0.05) comparable to the standard drug loperamide at the dose of 50 mg/kg of body weight. The overall results tend to suggest the antinociceptive and antidiarrhoeal activities of the extract.
