Purpose: The aim of this study was to analyze the concept of bloating in order to provide the basic information for appropriate nursing intervention. Methods: The concept analysis was used the method described by Walker and Avant(2005). Results: Bloating was usually considered the subjective sense caused by gas in large intestine. The symptoms of bloating was daily fluctuant. People with bloating reported that symptoms progressively worsened during the day and then discomfort was the most before bedtime. Bloating may be objectively assessed as measurement of abdominal girth, ect. The antecendents of bloating included the increased intestinal volume due to food sensitivity, aerophagia, constipation, and impaired peristalsis of bowel, and the brain-gut dysfunction induced by impaired viscerosomatic reflex, visceral hypersensitivity, and psychological factors. Consequences of bloating may affect the discomfort of life and physical activity adversely, and advance to the abdominal pain. Conclusion: We define the concept of bloating and suggest the method of relief bloating by control antecedents that induce bloating.

난황으로부터 레시틴 고함유 인지질을 회수하기 위하여 전처리, 표면반응분석기법을 실시한 결과 난황 인지질 분리조건(난황액 100g 기준)은 알코올 농도 95.83%, 알코올 첨가량 1: 6.51, 균질온도 $40.2^{\circ}C$, 20,000 rpm에서 5분간 균질한 후 원심 분리하여 여과 후 진공농축하고 아세톤 150 mL로 1회 세척하여 분리한 것으로 수율은 인지질 64.8%이상 레시틴 함량 55.04%의 인지질 분리를 위한 공정을 확립하였다. The optimum conditions for the extraction of lecithin from egg yolk were determined using response surface methodology (RSM). On the basis of the results of preliminary experiments, the most effective values were selected. The effects of three independent variables, dilution ratio, solvent composition, and extraction temperature on the response of crude egg lecithin (g) were then determined. The optimum conditions for egg lecithin separation obtained using ridge analysis were 6.51, 95.83%, and $40.2^{\circ}C$ for the dilution ratio, solvent composition, and extraction temperature, respectively. Using the optimum conditions, 55.04% of crude lecithin in total phospholipid can be obtained from 100 g liquid egg yolk. The experimental values (56.21% crude lecithin in total phospholipid) agreed with the predicted values.

This article concerns the labeling guideline for health benefits of livestock products. In recent years, livestock products with health benefits have emerged as a key market for livestock product industries. However, the current labeling regulation for functional foods severely prohibits livestock product industries from attaching most of the health benefits claims to the products. Also, manufacturers have some difficulties in labeling the health benefits of certain livestock products because of a lack of guidelines on health benefit claims for livestock products. Therefore, some livestock product industries and scientists have strongly demanded a revision of labeling regulation, Appended Chart No. 14 provided by Article 52 (2) of Enforcement Regulation of the Processing of Livestock Products Act, so they could mark the health benefits on their products. To support the 'revision of labeling regulation', the goals of this article were as follows; 1) to assess the current situation on nutrition labeling and nutrition claims on foods, 2) to determine the current situation on health claim regulatory systems used in foreign countries (CODEX, USA, Japan, EU, and Australia/New Zealand), 3) to assess the current situation on the health claim or health benefit claim regulations for functional foods, conventional foods, and livestock products in Korea, and 4) to determine the need for complement in health benefit claim for livestock products. In conclusion, guidelines for the use of health benefit claims on livestock products should be prepared as soon as possible and the guidelines should be viable and easy for manufacturers and control authorities to understand. Also, nutrient profiles should be developed to identify whether the livestock products are eligible to bear health benefit claims and to help consumers make the right choices.

계란급여에 따른 혈중지질특성과 콜레스테롤 대사에 관한 영향을 조사하기 위해 C57BL/6 마우스를 공시하여 일반식이군과 고콜레스테롤식이군으로 나눈 후 계란을 2%와 10% 첨가한 사료를 5주동안 급여하였다. 일반사양성적(체중, 사료섭취량, 사료효율), 혈액과 간조직, 분변의 지질함량 및 담즙산 농도를 측정하였다. 체중과 사료효율은 일반식이와 고콜레스테롤식이군 모두 유의적인 차이가 없었으나 사료섭취량은 10% 계란 첨가구에서 유의적인 증가를 보였다(p<0.05). HDL-C농도는 일반식이 급여군에서 2%와 10% 계란 첨가구 모두 유의적인 증가를 나타내었다(p<0.05). 간 조직 내 TG와 TC농도는 일반식이군에서 계란의 급여가 TG와 TC 증가에 영향을 미친 반면 고콜레스테롤식이군의 경우 TG는 유의적인 차이가 없었고, TC는 10% 계란 급여군에서 감소하였다(p<0.05). 분변의 콜레스테롤, 중성지질, 담즙산 농도는 일반식이군과 고콜레스테롤식이군 모두 계란의 첨가 수준이 증가할수록 TC와 TG함량이 유의적으로 증가하였다(p<0.05). 담즙산 농도 역시 일반식이 급여군에서 계란의 첨가수준이 증가할수록 대조군보다 높은 함량을 보여 계란이 분변의 콜레스테롤 함량에도 영향을 미친 것으로 판단된다. This study was conducted to evaluate the effect of whole egg supplementation on the blood lipid profiles and cholesterol levels of C57BL/6 mice. Sixty-six mice were divided into two groups: normal-diet supplemented and high-cholesterol diet supplemented. Lyophilized whole egg powder was mixed with the two diets at 2 and 10%: normal diet only, normal diet with 2 and 10% whole egg powder, high cholesterol diet only, high cholesterol diet with 2 and 10% whole egg powder. The mixed diets were fed for 5 wk and feeding condition (body weight change, feed intake, and feed efficiency ratio (FER)), blood lipid profiles (total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein cholesterol, hepatic and fecal lipids (TG, TC)), and fecal bile acids were determined. No significant differences were found in body weight gain or FER after whole egg supplementation in both the normal and high-cholesterol diet fed groups. In the normal-diet fed mice, HDL-C increased significantly in the 2 and 10% whole-egg powder groups. In the high-cholesterol diet fed mice, administering 10% egg powder increased the atherogenic index compared to the control. Furthermore, administration of whole egg powder increased fecal bile acids dose dependently (p<0.05). These results indicate that administering 2% hen whole egg powder did not affect blood lipid profiles and was more beneficial for health by increasing HDL-C and aiding in the excretion of cholesterol by fecal bile acids than those in the control.

The antioxidant and antimicrobial activities of pork patties supplemented with medicinal herb extract mix were investigated. The medicinal herb extract powder was mixed at a ratio of 48.5:48.5:3.0 for Morus alba L, Lonicera flos, and Coptis chinensis, respectively. The pork was prepared and supplemented with medicinal herb extract mix (0, 0.5, 1, or 2%) and the antioxidant and antimicrobial activities were tested during storage at $4^{\circ}C$. The pH value decreased during cold storage at $4^{\circ}C$ for allsamples, however the pH of samples supplemented with herb extract mix rapidly decreased by days 5 and 10 ($p{\leq}0.05$). The total phenol content in the pork patties with herb extract mix was higher than in the control patties. The ABTS+ radical scavenging activities increased with increasing concentrations of herb extract mix from 0.5% to 2%. In addition, pork patties supplemented with herb extract mix showed an approximately 1 decimal reduction in total aerobic counts. Therefore, the addition of herb extract mix into pork patties increased the antioxidant activity and slightly improved the antimicrobial activity of pork patties during cold storage. However, the levels of added medicinal herb extract mix should be considered prior to its use in order to maintain proper sensory acceptance.

The effects of fermented goat milk supplemented with citrus concentrate on blood glucose levels in streptozotocin-nicotinamide-induced diabetic rats were examined. Streptozotocin-nicotinamide-induced diabetic rats (type II) were divided into five experimental groups treated with metformin, goat milk, fermented goat milk, fermented goat milk containing citrus concentrate, or no supplementation (control). The rats in each group were examined weekly for blood levels of glucose, total cholesterol, triglyceride. HDL-cholesterol, LDL-cholesterol. and body weight. On the $24^{th}$ day of the experiment, an oral glucose tolerance test (OGTT) was carried out. Administration of fermented goat milk to the diabetic rats significantly decreased blood glucose and triglyceride levels, while administration of metformin (33.3 mg/kg body weight) did not significantly lower blood glucose levels. Fermented goat milk containing citrus concentrate caused a significant decrease in blood glucose levels in the OGTT at 30 min. This study shows that supplementation with fermented goat milk containing citrus concentrate may be a practical method of reducing blood glucose levels in type II diabetics.

The aim of this work was to establish the standard for goat milk somatic cell counts. The data were obtained from MGEN, which were collected from Dec. 2006 to Nov. 2007. A total of three hundred and forty somatic cell counts from 12 goat milk farms were analyzed. A goat milk grading system by somatic cell count is proposed; less than 1,000,000/mL, 1,000,000-1,500,000/mL, 1,500,000-2,000,000/mL, 2,000,000/mL-2,500,000/mL, and over 2,500,000/mL. Under the grading system, the ratio of first grade goat milk would be 26.2%, and that of the fifth grade would be 11.8%. The first grade ratio is low and the fifth grade ratio is high compared to the cow milk grading system. It is expected that somatic cell counts of domestic goat milk will be improved by the proposed grading system.
