  • 본 연구에서는 저열량식이요법의 부작용 증세중 체력저하를 개선할 수 있도록 동의보감의 처방중 체력 증진과 연관된 보음(補陰), 보혈(補血) 기능을 갖는 사물탕(四物楊)을 기반으로 하여 개발된 생약 조성물의 체력 증진 기능을 규명하고자 실시하였다. 저열량식이요법의 모델로서 섭취 식이량의 50%를 제한하는 제한식이를 2주간 실시한 결과 제한식이를 섭취한 군은 강제 수영 모델에서 총 수영 시간이 감소하고 근육내 ATP 함량의 감소, 혈액중 젖산 함량의 증가가 나타나 식이 제한에 의해서 체력 감소가 나타남을 확인할 수 있었다. 본 연구에서 사용된 산야초 추출물을 동일하게 식이제한을 한 실험동물에게 섭취시킨 결과 총수영시간의 증가와 근육내 ATP의 증가, 젖산 함량의 감소가 나타나 저열량식이에 의한 부작용인 체력 저하를 산야초 추출물이 완화시킬 수 있는 기능이 있음을 확인 할 수 있었다. 또한, 산야초 추출물의 투여는 체력과 높은 연관성이 있는 것으로 알려진 혈중 IGF-1의 농도를 증가시키는 것이 관찰되어 체력 향상에 도움을 주는 것으로 추측된다. 식이 제한 환경에서 나타날 수 있는 천연물 추출물의 독성을 확인하기 위하여 간기능 지표인 GOT, GPT를 측정한 결과 특별한 변화가 나타나지 않아 산야초 추줄물의 안전성을 확인할 수 있었다.

  • In order to prevent pollution from animal waste, P, N and pharmacological level minerals should be properly managed. Microbial phytase has been used successfully to control P excretion. Activity of natural phytase in certain plant feedstuffs is high enough to be considered in feed formulation. Nitrogen control can be achieved through amino acid supplementation and protein restriction in the diet. Supplementation with carbohydrases reduces output of excreta as well as N. Ammonia release from the manure could be reduced by using a low crude protein diet along with the supplementation with probiotics products. Excretion of minerals used at pharmacological level can be reduced by using chelated forms. Cu and Zn in the form of methionine chelate have been successfully used in the broiler and pig diets.

  • Infants and children with food related Atopic dermatitis (AD) need extra dietary efforts to maintain optimal nutrition due to food restriction to prevent allergy reactions. However, nutrition ignorance and food faddism make patients even more confused and practice desirable diet more difficult. The objective of this study was to report the AD patients' malnutrition cases in Korea.(omitted)

  • Purpose: Management of eosinophilic esophagitis (EoE) varies from center to center. In this study, we evaluated the effectiveness of a dairy-free diet (DFD) and the 6-Food Elimination Diet (SFED) as initial therapies for the treatment of EoE in our practice. Methods: This was a retrospective study of children who had been treated for EoE at Connecticut Children's Medical Center, Hartford, CT, USA. Pre- and post-treatment endoscopy findings and histology results of patients treated with DFD or SFED were examined. Results: One hundred fifty-two patients (age 9.2±5.2 years, 76.3% male, 69.7% caucasian) met the inclusion criteria for initial treatment with DFD (n=102) or SFED (n=50). Response for DFD was 56.9% and for SFED was 52.0%. Response based on treatment duration (<10, 10-12, and >12 weeks) were 81.8%, 50.0%, and 55.1% for DFD, and 68.8%, 50.0%, and 40.0% for SFED. Response based on age (<6, 6-12, and >12 years) were 59.3%, 42.9%, and 67.5% for DFD, and 36.4%, 58.8%, and 72.7% for SFED. In patients treated with DFD, concomitant proton pump inhibitor (PPI) administration resulted in improved outcomes (p=0.0177). Bivariate regression analysis showed that PPI with diet is the only predictor of response (p=0.0491), however, there were no significant predictors on multiple regression analysis. Conclusion: DFD and SFED are effective first line therapies for EoE. DFD should be tried first before extensive elimination diets. Concomitant therapy with PPI's may be helpful.

  • BACKGROUND/OBJECTIVE: The goal of the present study was to investigate the effects of moderate caloric restriction on ${\beta}$-cell function and insulin sensitivity in middle-aged obese Korean women. SUBJECTS/METHODS: Fifty-seven obese pre-menopausal Korean women participated in a 12-week calorie restriction program. Data on total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglycerides (TG), and fasting serum levels of glucose, insulin, C-peptide, blood pressure, leptin and anthropometrics were collected. A dietary intake assessment was based on three days of food recording. Additionally, ${\beta}$-cell function [homeostasis model assessment of ${\beta}$-cell (HOMA-${\beta}$), insulinogenic index (ISI), C-peptide:glucose ratio, and area under curve insulin/glucose ($AUC_{ins/glu}$)] and insulin sensitivity [homeostasis model assessment for insulin resistance (HOMA-IR), Quantitative insulin-sensitivity check index (QUICKI) and Matsuda index (MI)] were recorded. RESULTS: When calories were reduced by an average of 422 kcal/day for 12 weeks, BMI (-2.7%), body fat mass (-10.2%), and waist circumference (-5%) all decreased significantly (P < 0.05). After calorie restriction, weight, body fat percentage, hip circumference, BP, TC, HDL-C, LDL-C, plasma glucose at fasting, insulin at fasting and 120 min, $AUC_{glu}$ and the insulin area under the curve all decreased significantly (all P < 0.05), while insulin sensitivity (HOMA-IR, QUICKI and Matsuda index) measured by OGTT improved significantly (P < 0.01). CONCLUSIONS: Moderate weight loss due to caloric restriction with reduction in insulin resistance improves glucose tolerance and insulin sensitivity in middle-aged obese women and thereby may help prevent the development of type 2 diabetes mellitus.

  • Purpose: This survey was aimed to examine the current dietary restrictions practices for neutropenic patients among hospitals with 500 and more beds. Methods: Self-administered questionnaires were sent to 100 head or charge nurses of oncology or hemato-oncology wards by mail during October 2009, and 51 questionnaires were returned. The data were analyzed with descriptive statistics using SPSS (WIN version 12.0). Results: Of the hospitals surveyed, 47.1% (n=24) had guidelines on the dietary restrictions, and 80.4% (n=41) placed patients with neutropenia on restricted diets. The major decisional criteria of the dietary restriction was absolute neutrophil count (30.5%) and cooking status (29.2%). The most commonly restricted foods were raw fish or fresh meat (98.0%), uncooked intestine (98.0%), raw eggs (98.0%), draught beer (96.1%), and fresh fruits or vegetables (86.3%). Conclusion: The results showed variation in pattern of dietary restrictions and lower rate of guideline among hospitals, so that the need for the standard dietary restriction guideline is high. However, the role of diet in the development of infection in neutropenic patients is still unclear, which makes it difficult to establish dietary restriction guideline. Therefore, additional research are required to identify the relationship between dietary factors and infections.

  • Fiftysix male weanling rats of the Sprague-Dawley strain weighing $52.6{\pm} 0.9g$ were fed with 77% starch-15% casein diet by ad libitum for four days to get them adapted and divided into eight groups. For three weeks, the body weight gain of rats was controlled in three different ranges. After the period of food restriction, the rats were recovered by being fed by ad libitum for seventeen days. During the experimental period, the amount of food intake and body weight were measured. And the experimental groups were compared when they reached at the same age and at the same body weight. Anterior Tibialis, Extensor Digitorum Longus, Soleus, Plantaris, Gastrocnemius were used as analytic items of skeletal muscle. Wet weight of muscle, muscle protein, water content were measured from each of five skeletal muscles. Sodium, potassium, magnesium content were measured from Anterior Tibialis, Extensor Digitorum Longus, Soleus ana Plantaris. Phosphorus was measured only from Gastrocnemius. The whole carcass protein except the skeletal muscles was also measured. During the period of food restriction, food intake was $311.7{\pm}19.5g$ for the control group. $130.2{\pm}1.5g$ for the second group and $161.7{\pm}2.1g$ for the third group. During the period of food restriction, body weight gain was $106.8{\pm}12.7g$ for the control group, $3.6{\pm}2.1g$ for the second group and $18.9{\pm}3.3g$ for the third group. Comparing the body weight when they reached at the age 66 days, the control group showed higher value than the other groups. In the concentration of electrolytes of skeletal muscles sodium and magnesium tend to increase and potassium and phosphorus tend to decrease by food restriction. But after their recovery, there was no significant difference between the groups. By the degree of food restriction, there was time difference in reaching at the same body weight. But when they reached at the same body weight, there was no significant difference in the value of electrolytes concentration. Regarding all the results of this study, the ages of rats which reached the same body weight were different by food restriction level during weanling. Once food·restricted rats reached the same body weight by recovery, the concentration of electrolytes and protein tend to become almost the same.
