The incidence and etiology of parasite-associated gastroenteritis during 2004-2006 in Gyeonggi-do (province), South Korea was determined by means of antigen detection ELISA on 6,071 stool specimens collected from 6 general hospitals. At least 1 parasitic agent was detected in 3.4% (208/6,071) of the stool samples. Among these, Giardia lamblia was the most numerous (152 cases; 2.5%), followed by Entamoeba histolytica (25 cases; 0.4%), Cryptosporidium parvum (23 cases; 0.4%), and mixed infections (8 cases; 0.1%). Patients aged 1-5years had the largest proportion (69.2%; 144/208) of parasite-positive stool specimens. Parasite-mediated gastroenteritis was most common from June to September. The detection rate gradually increased from 2004 to 2006. This study shows that parasite-mediated gastroenteritis may be significant among children in Korea and that parasite infection surveillance should be constantly performed.

The researcher intended to investigate the rate of absenteeism and other related statistics among the workers in a steel and iron industry with the criteria and the recommendation of the International Association on Occupational Health. With the well designed questionaire and interview, 1,882 workers were surveyed from July the 24th to the 28th, 1978. The results were as follows; The workers who experienced absence were 16.8% in July. The rate of frequency (spells) was 3.24, the duration was 4.65, the frequency (persons) was 345.20, and the lost time was 1.27. 41.0% among the absentee experienced sickness absences and the rates of sickness absence were as follow; the frequency (spells) nab 1.34, the duration was 2.29, the frequency (persons) was 101.06 and the lost time was 0.63, respectively. The main causes of sickness absence were general symptoms, such as fatigue (50.8%) and gastro-intestinal symptoms (13.8%). The frequency of sickness was highly correlated to the frequency of drinking, the amount of smoking, the physical work-load and the amount of drinking, which was analysed by the stepwize multiple regrssion analysis. The multiple R due to the above mentioned four variables was 0.320 and the R square was 10.3%.

Probiotics may be defined as microbial agents that can benefit humans and have been used primarily by mankind in fermented foods. A representative of probiotics is lactic acid bacteria (LAB), which has received attention recently due to its perceived health benefits. We reviewed research papers about Bifidobacerium and Lactobacillus, which are two of the most known of the LAB. Bifidobacerium alleviates diarrhea from various causes by improving intestinal microflora, and it has been reported that it reduces Helicobacter pylori bacteria known as the cause of gastric ulcer and stomach cancer. Bifidobacerium has also reported to be effective on immunization and allergy, reduce blood cholesterol, cancer, lactose intolerance. Lactobacillus alleviates diarrhea but has not fully demonstrated its effectiveness relative to other health issues. Several lactic acid bacteria and yeast are expected to act as probiotics, so, in the future, more research on the health benefits of lactic acid bacteria is needed.

Disease associated with microorganisms are far from resolved by current therapeutics. One of effective approach to health maintenance and disease control is the use of dietary bacterial and carbohydrate supplements. This comprises use of probiotics and prebiotics. Probiotics mean the live microorganisms, which when administered in adequate amounts confer a health benefit on the host. Prebiotics mean a nondigestible food ingredient that beneficially affects the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria that can Improve the host health. Especially, probiotics has the relation which is close with innate immunity and adaptive immunity. And probiotics has the clinical value with many disease like lactose intolerance, constipation, acute gastroenteritis, food hypersensitivity and allergy, atopic dermatitis, crohn's disease, rheumatoid arthritis, pelvic radiotherapy, intestinal inflammation and chemical exposure, colon cancer, inhibitory effect of Helicobacter pylori and lowering the level of cholesterol. We use jointly korean medicine and probiotics and it has the more therapeutic effect in the many disease.

This study was designed to investigate the health promotion effect of fermented milk and historical story of Korean dairy products from the ancient period to present. Although the origin of fermented milk is Europe, the recede of fermented milk was founded in far-east and middle east areas at BC 4C. After the spread of fermented milk to Korea and Japan. The consumption of fermented milk in Korea was dramatically increased to 14.2 kg per person in 1997. Health promotion effect of fermented milk can be devided to 5 major effected improvements of intestinal microflora, anticancer, cholesterol assimilation anti-pathogenic activity. Fermented milk reduced the level of ${\beta}$-glucornidase and nitroreductase to 50% and it provides anticancer activity by cell wall an polysaccharides. Fermented milk has cholesterol assimilation activity ca. 54${\sim}$40% (B. longum, Str. thermophillus). Anti-pathogenic activity of fermented milk was significant. It appeared that Sal. ser. typhimurium was more susceptible than 5. coli 0157 at low pH fermented milk. Viable cells of E. coli 0157 were not dramatically decreased in most of fermented milks tested, but in general, Sal. ser. typhimurium was drastically decreased in most of the fermented milks.

Pathogenic Salmonella typhimurium can invade the intestinal epithelium and cause a wide range of diseases including gastroenteritis and bacteremia in human and animals. To identify the genes involved in the infection, the invasion determinant was obtained from S. typhimurium 82/6915 and was subcloned into pGEM-7Z. A subclone DHl (pSV6235) invaded HEp-2 and Chinese hamster ovary epithelial cells and contained a 4.4 kb fragment of S. typhimurium genomic region. Compared with the host strain E. coli DHl, the subclone DHl (pSV6235) invaded cultured HEp-2 and Chinese hamster ovary cells at least 75- and 68-fold higher, respectively. The invasion rate of E. coli DHl for the cells significantly increased by harbouring the genomic region derived from pathogenic S. typhimurium 82/6915.

Purpose: Hydrogen-methane breath tests are used to diagnose carbohydrate malabsorption and small intestinal bacterial overgrowth. The COVID-19 pandemic has driven the modification of procedures as breath tests are potentially aerosol-generating procedures. We assessed the effect of delayed analysis of breath samples, facilitating the at-home performance of breath testing. Methods: Children provided two breath samples at every step of the lactose breath test. The samples were brought back to the clinic, and one set of samples was analyzed immediately. The second set was stored at room temperature and analyzed 1-4 days later. Results: Out of the 73 "double" lactose breath tests performed at home, 33 (45.8%) were positive. The second samples were analyzed 20 to 117 hours after the first samples (41.7±24.3 hours). There was no significant difference in the hydrogen concentration between the first and second sets (Z=0.49, p=0.62). This was not the case for methane, which had a significantly higher concentration in the second breath samples (Z=7.6). Conclusion: Expired hydrogen levels remain stable in plastic syringes if preserved at room temperature for several days. On the other hand, the delayed analysis of methane appeared to be less reliable. Further research is needed to examine the impact of delayed analysis on methane and hydrogen concentrations.

Recently, the concept of personalized nutrition has been developed, which states that food components do not always lead to the same metabolic responses, but vary from person to person. Although this concept has been studied based on individual genetic backgrounds, researchers have recently explored its potential role in the gut microbiome. The gut microbiota physiologically communicates with humans by forming a bidirectional relationship with the micronutrients, macronutrients, and phytochemicals consumed by the host. Furthermore, the gut microbiota can vary from person to person and can be easily shifted by diet. Therefore, several recent studies have reported the application of personalized nutrition to intestinal microflora. This review provides an overview of the interaction of diet with the gut microbiome and the latest evidence in understanding the inter-individual differences in dietary responsiveness according to individual baseline gut microbiota and microbiome-associated dietary intervention in diseases. The diversity of the gut microbiota and the presence of specific microorganisms can be attributed to physiological differences following dietary intervention. The difference in individual responsiveness based on the gut microbiota has the potential to become an important research approach for personalized nutrition and health management, although further well-designed large-scale studies are warranted.

Paralytic ileus is a metabolic state in which the intestines fail to transmit peristalsis due to failure of the neuromuscular mechanism in the small intestines and colon. It is a major cause of morbidity in hospitalized patients especially during late presentations and points of mismanagement. The causes include infections, electrolyte imbalance (hypokalemia, hyponatremia), surgeries and medications. When the exact cause of the disease condition is identified and corrected, paralytic ileus is usually resolved. This case report is that of a 16 year old female who was admitted and managed as a case of paralytic ileus. The patient presented with symptoms of fever, abdominal pain, abdominal distension, vomiting and inability to pass stool or flatus. There was associated body weakness, reduced urine output and weight loss. She was properly examined clinically and sent for various investigations. Investigations such plain abdominal X-Ray, serum electrolyte estimation, chest X-Ray and full blood count were carried out. The results of the investigations done were in keeping with the diagnosis of paralytic ileus, electrolyte imbalance and ongoing sepsis. She was subsequently managed through nil per oral, adequate fluid rehydration, antibiotics and correction of electrolyte imbalance. Following stable clinical state and investigation results, she was discharged and advised on follow-up.
