Gastrointestinal tract is an organ for digestion, absorption and utilization of nutrients. Also it functions as an immunological organ in the human body. Patients with gastrointestinal disease are at increased risk for nutritional problem due to dietary restriction during the treatment or diagnostic examinations, anorexia or altered nutritional requirement. Clinically, it is important for gastroenterologists to be aware of the principles of nutritional therapy and the relationship between gastrointestinal diseases and the combined nutritional abnormalities. Removal of enteral feeding causes mucosal atrophy and leads to increased mucosal permeability to bacteria and endotoxin. The intestinal endotoxemia results from the translocation of bacteria and endotoxin to systemic circulation, may triggers off systemic inflammatory response syndrome. Therefore, it is crucial in critically ill patients to maintain the gastrointestinal mucosal integrity along with the intestinal flora that enables the host immunity to be maintained or enhanced. Immunonutrition is a therapeutic approach to enhance the gastrointestinal mucosal barrier with various specific nutrients. The intestinal endotoxemia and immunonutrition will also be reviewed briefly. (Korean J Gastroenterol 2004;43:331-340)

농업용저수지의 누수, 함몰, 균열 등 재해예방을 위한 위험징후 조기발견 및 대응능력 제고를 위하여 저수지 예초 작업을 수행하여야 한다. 저수지 예초 작업은 인력을 투입하여 추진하고 있으나 수많은 저수지를 유지관리하기에는 예산이 부족한 상황이다. 따라서 한국농어촌공사에서는 3,000여 곳의 저수지를 효율적으로 유지관리하기 위하여 경사면 광역예초기를 활용하고 있다. 경사면광역예초기란 일반적으로 골프장 잔디 깎기 장비와 유사하나 경사가 급한 저수지 사면부 예초 작업을 수행하기 위한 유지관리 장비이다. 경사면광역예초기를 효율적으로 운영한다면 유지관리에 소요되는 예산 절감뿐만 아니라 예초 작업의 효율성이 향상 될 것으로 사료된다.

Purpose: Several studies that focused on hospital malnutritionhave reported that more than 40% of hospitalized patients have nutritional risk factors, and there is a high prevalence of hospital malnutrition. People with a more severe malnutrition status had a longer length of hospital stay and higher hospital costs. Therefore, the net result from early nutritional support may be improved organ function, decreased infection, reduced morbidity and mortality and decrease the hospital stay and cost. Methods: We investigated the patients who received tube feeding or parenteral nutrition for more than 3 days. We recommended the nutritional assessment, the patients` requirements, the route of feeding and the proper formula to the clinicians. Some of them followed our suggestion and some didn`t. Thus, we divided groups into two subgroups according to this. The clinical outcomes of the two groups were compared. Results: There were no significant differences in the clinical outcomes between the two groups. However, the patients who received enteral feeding increased from 10% up to 70% in the experiment group. In spite that the gastrointestinal route could have been used, only 44.4% of the patients in the control group received enteral feeding. Conclusion: More rapid and adequate nutritional support through enteral nutrition must be considered to produce the effective clinical outcomes in critically ill patients. The patients who require nutritional support need continuous follow up care and monitoring by a nutritional support team (NST). (KJPEN 2010;3(1):40-44)

It is known that onion increases anti oxidative and antibiotic capacity, and decreases blood pressure and cholesterol levels. The study was carried out to investigate whether ethanol extract of onion can enhance blood lipid profiles in hypercholesterolemic patients. Fourty three hypercholesterolemic patients were randomly divided into 2 groups; 25 in controls and 18 in experimental group. The control group was offered to take placebo for 4 weeks (200 ㎖/day), and experimental group was offered to consume ethanol extract of onion for 8 weeks (200 ㎖/day that corresponds to 500 g of onion). There were no differences in sex, age, body mass index (BMI) and educational levels between groups before treatment. After 8 weeks of onion extract consumption, plasma triglycerides level was significantly decreased in experimental group compared to control (p<0.05). Total cholesterol level was tended to decrease in experimental group, but there was no significant difference of change between control and experimental group. The levels of plasma glucose and LDL-cholesterol were not changed significantly after onion extract consumption. In summary, alcohol extract of onion may have a positive effect on the lipid profiles of hypercholesterolemia patients through decreasing plasma triglyceride concentration.

Malnutrition is a common health problem in people older than 65 years. In older individuals, malnutrition is associated with poor clinical outcomes and even death. These individuals particularly are characterized by inadequate nutritional intake due to various factors such as medical disease, physical impairment, age-related physiological changes, and psychological and psychosocial issues. Furthermore, as the immune system ages, its function is compromised, and the aged person becomes more vulnerable to harm and disease. Nutrition plays an important role in maintaining the vigor of the immune system, because nutritional deficits and malnutrition can aggravate a diseased condition because of the weakened immune system. It is important to assess older individuals for malnutrition, particularly when weight loss or anorexia is observed. Nutritional status in older individuals is generally assessed with the revised mini-nutritional assessment short form, the malnutrition universal screening tool, and the nutritional risk screening 2002. A structured approach is essential for the management of unintended weight loss or malnutrition in older individuals. Studies have shown that oral nutritional supplementation, a wellestablished approach, can improve nutritional status and quality of life in older individuals. Pharmacological treatments, such as administration of megestrol acetate, dronabinol, testosterone, oxandrolone, and rh-growth hormone, require further investigation to assess whether they are fit for clinical application.

Purpose: The aim of this study is to determine the efficacy and safety of Cordyceps militaris in Korean adults with mild liver dysfunction. C. militaris is a mushroom traditionally used for several clinical purposes in East Asian territory, including China, and has been found to be effective in improving liver function through animal studies. Methods: The C. militaris group was administered 1.5 g/day of C. militaris (2 capsules per dose, twice per day) and the placebo group was administered the same volume of placebo. Laboratory test (white blood cell, hemoglobin, platelet, aspartate aminotransferase, alanine aminotransferase, gamma glutamyltranspeptidase, lactic dehydrogenase, alkaline phosphatase, total bilirubin, blood urea nitrogen, creatinine), liver computed tomography (CT) were performed, and visual analogue scale score for subjective symptoms and fatigue severity scale were measured. Results: In analysis of the liver CT scan at 8 weeks after administration compared to baseline, the mean ratio of change of Hounsfield unit of 8 segments of liver increased by an average of 21.43%±45.11% in the C. militaris group and 9.64%±11.41% in the placebo group. Others showed no statistically significant inter-group difference. Conclusion: C. militaris extract was used safely as a functional food in patients with mild liver dysfunction, and is expected to protect against progression of fatty liver or cirrhosis caused by suppression of lipid accumulation in hepatocytes.

Purpose: In Korea, the prevalence of metabolic syndrome has increased. The relationship between metabolic syndrome, adiponectin, and dietary components is widely known. However, the relation between cytokine and dietary components is not yet well studied in Korea. Methods: Five hundred and ninety-six Korean adults between 30 and 59 years of age were recruited by advertisement to the Bundang Jesaeng General Hospital (BJGH), and those not taking regular medications and without diagnoses of fulminant disease were included. Data was collected on anthropometric measurements, diagnostic parameters for metabolic syndrome (MetS), and 3-day dietary intakes from individuals in the study. Results: Serum adiponectin level was positively correlated with serum HDL-cholesterol level and was negatively correlated with BMI, waist circumference, and systolic and diastolic blood pressure. Intake of dietary fiber was high in the high-adiponectin group. Conclusion: High-fiber diet and adiponectin can be helpful for improving metabolic syndrome. (JKSPEN 2011; 4(1):16-20)
