The flow behaviors of three thickened fruit juices (orange, apple, and grape juice) prepared with a commercial instant xanthan gum (XG)-based thickener that is marketed in Korea were investigated at different thickener concentrations (1.0%, 1.5%, 2.0%, 2.5%, 3.0%, and 3.5%) and setting times (5 and 30 min) using a rheometer and a line-spread measurement method. The flow distance values measured by the line-spread test (LST) were compared with the apparent viscosity (${\eta}_{a,50}$) values measured with a sophisticated computer-controlled rheometer. The ${\eta}_{a,50}$ values of the juices increased as thickener concentration increased, whereas their flow distances decreased. The ${\eta}_{a,50}$ values at the 30-min setting time were much higher than those at the 5-min setting time, indicating that the setting time before serving or consuming thickened juices can affect viscosity values. Plots comparing ${\eta}_{a,50}$ values to LST flow distances revealed strong exponential relationships between the two measures ($R^2$=0.989 and $R^2$=0.987 for the 5- and 30-min setting times, respectively). These results indicate that the LST can be a suitable instrument for evaluating the viscosity of thickened fruit juices prepared with different XG-based thickener concentrations and setting times for the dysphagia diet.

In Oriental medicine, So-gal(消渴) is similar to Diabetes Mellitus in the symptoms. In the medical treatment of So-gal(消渴), one kind of herb medicine is recorded in ancent medicine literatures. That herb medicine is a juice of vegetable drunken with herb medicine of So-gal(消渴). Milk(牛乳汁), human milk(人乳汁), gam-ja-jup(甘蔗汁), wo-jul-jup(藕節汁), li-jup(梨汁), sang-gang-jup(生薑汁) etc. is that. In that juices, Milk(牛乳汁), human milk(人乳汁), gam-ja-jup(甘蔗汁), wo-jul-jup(藕節汁), li-jup(梨汁) have sweety tastes, and cold nature. So they cure So-gal(消渴) come from dry and hot nature. Sang-gang-jup(生薑汁) is different with others in the taste and nature that sweety and hot taste and hot nature. Sang-gang-jup(生薑汁) cure the sequela of So-gal(消渴) by his hot nature. We think In Diabetes Mellitus, that juice can be used by drink for the treatment of diet because of simility between So-gal(消渴) and DM.

Organic acid and sugar contents in ten kinds of juices (two orange juices, two grape juices, two aloe juices, two citron juices, one bokbunja, and one grapefruit juice) were analyzed by high-performance liquid chromatography. Citric acid was detected in all the fruit juices analyzed. Grape juices contained the highest tartaric acid content (67.85 - 99.37 mg/100 mL) while orange and grape juices contained a high content of malic acid (151.67 - 211.18 mg/100 mL). Lactic acid was detected in all the aloe juices (35.12 - 65.27 mg/100 mL) as well as in one orange (203.8 mg/100 mL) and one grape juice (112.28 mg/100 mL). Citrus fruit juices (A, A', F) showed the highest content of total organic acids as 902.81 - 1,103.7 mg/100 mL. With regard to sugar contained in the juices, lactose and maltose were not detected in any of the fruit juices. Even when comparing the same kind of fruit juice, sugar (fructose, glucose, and sucrose) content showed a significant difference (p < 0.05) depending on the manufacturer. In the grape juices, contents of fructose (6.86 - 7.51) and glucose (6.23 - 7.3 g/100 mL) were higher than in other juices. One serving size of the juices (180 mL) analyzed in this study can provide approximately 3.3 - 4.9% of total daily energy requirements when consumed as part of the 2,200 kcal/day diet required for an adult.

Red Chinese cabbage is rich in anthocyanins, with beneficial effects on anti-obesity and lipid profiles. The purpose of this study was to examine the anti-obesity effects of red Chinese cabbage. Four-weeks old Spague-Dawley male rats were divided into four groups for six weeks as follow: Normal Diet (ND), High Fat Diet (HFD), HFD + Red Chinese Cabbage Diet (RCD), HFD + Red Chinese Cabbage Juice (RCJD). After six weeks, the liver weight was significantly higher in the HFD group than in the other groups, and the RCD and RCJD groups showed similar values to the ND group. The epididymal fats were significantly higher in all high fat diets (HFD, RCD, RCJD) than in the ND group and there was statistical significance in the post-tests when comparing the RCD and RCJD groups with the HFD group. Triglycerides significantly decreased in the RCD group. In conclusion, red Chinese cabbage is rich in anthocyanins, with beneficial effects on organ weight and lipid profiles.

This descriptive study was designed to identify the factors associated with weight control behaviors among 273 high school girls with normal body weight. The objectives of the study were ⅰ) to evaluate subjective obesity and satisfaction with the body shape, ⅱ) to describe the weight control behaviors and the motivation, ⅲ) to reveal the relationships between the weight control behaviors and BMI (Body Mass Index), iv) to investigate the relationships between the weight control behaviors and subjective obesity and satisfaction with the body shape, and v) to investigate the relationships between the weight control behaviors and family support. The results showed that 62.6% of the adolescent girls with normal weight perceived that they were fatty and 9.9% thought they were obese. Seventy-five percent of them were not satisfied with their body shape. Eighty percent of the participants reported the main motivation of weight control was to have an attractive appearance. In this study, self-reported weight control methods included dieting (64.8%, skipping or reducing meals), exercise (36.6%), and special dieting (20.1%) such as eating an increased amount of juice or vegetables. It was shown that the subjects who were not satisfied with their body shape and perceived themselves as fatty or obese were active in exercise, diet, and other special diets. Subjects who were on diets and special diets had a higher level of BMI than who were not on diet and special diet. Subjects who exercise had a lower level of BMI than who did not exercised. Family support was significantly related to exercise behavior. The research suggested that there is a increasing responsibility for school nurse to instruct on the body shape and weight control behaviors through health education and consultation. Also, the results suggested that it is important to develop proper diet and exercise methods for adolescents girls to maintain their weight and health.

This study was to investigate the effect of chitosan-ascorbate (CA) prepared with different molecular weight (223, 746, 1110 and 2025 kDa) on the fermentation and quality of mul-kimchi, and also, the effect of the mul-kimchi juice fermented with 0.1% chitosan-ascorbate prepared with 2025 kDa chitosan (CA2025) on the serum lipids of rae fed with high cholesterol diet (HC). The mul-kimchi fermented in 0.1% CA2025 has lower turbidity, longer shelf-life, higher glucosamine content and SOD activity than those of control and the other treatments. In the animal experiment the HC-CA2025 and HC-2CA2025 groups which were administered 0.5 mL per 100 g body weight of mul-kimchi juice fermented with 0.1% CA2025 and administered the same volume of the juice concentrated 112 per nay fed for 5 week, respectively. The average body weight of the HC-CA2025 and HC-2CA2025 group was lower 6.9% and 8.4% than that of HC control group respectively. Total serum cholesterol contents of these groups were 88.33 and 85.00 mg/uL, which were 17.45% and 20.56% lower than HC control group respectively. While, HDL-cholesterol content of these groups were 7% and 23%, higher the LDL-cholesterol content were 13% and 26% lower than those of HC control group respectively. And also, though the atherogenic index, AST and ALT activities were not reached to normal control group, the values were remarkably lower than those of HC control group. This study indicates the possibility of utility for kimchi industry by adding chitosan-ascorbate, especially CA2025 showing not only quality enhancing and shelf-life prolongation but also improving serum lipids and atherogenic index in rats fed with high cholesterol diet.

This experiment was conducted to study the effect of addition of Lucerne juice (LJ) obtained by mechanical extraction of freshly harvested crop on the nutritive value of rice straw silage. Rice straw (RS) was ensiled with intact, NaOH or $NH_3$ treated LJ at 3:7 ratio on fresh weight basis (LJ RS, LJ NaOH RS and LJ $NH_3$ RS, respectively). Each alkali was mixed with fresh juice at a level of 4% of rice straw dry matter just before ensiling. Rice straw ensiled with water was prepared as the control (W RS). In the digestion trial, goats were allocated in a $4{\times}4$ Latin-square design and fed the diet containing three parts of RS silage and one part of wheat bran (DM basis). For the goats receiving the control silage, urea was supplemented at feeding time so as to adjust the nitrogen intake except for goats on LJ $NH_3$ RS silage. Crude protein content of RS silage was increased from 5.2 to 9.1% (DM basis) by the addition of intact LJ and to about 24% by $NH_3$ treated LJ. The control W RS silage contained only trace amount of lactic acid and was dominated by acetic and butyric acid. The addition of intact LJ reduced butyric acid content and $NH_3-N/TN$ of the silage whereas the addition of alkalized LJ increased those values and shifted to a butyrate type fermentation. Nutrient digestibilities and nitrogen balance of goats were almost the same when they were fed W RS and LJ RS silage indicating the addition of intact LJ did not improve the nutritive value. The addition of alkalized LJ significantly increased the fiber digestibilities of RS silage and $NH_3$ treatment was more effective than NaOH treatment. Postprandial ruminal $NH_3-N$ and blood urea nitrogen (BUN) concentrations were decreased by feeding LJ NaOH RS silage suggesting ruminal protein synthesis was enhanced along with the increase of energy supply for supply for rumen microbes by the alkali treatment. The advantageous fiber digestibilities of LJ $NH_3$ RS silage compared with those of LJ NaOH RS silage might be attributable to a sufficient nitrogen supply for microbial fiber digestion in the rumen.

An amine rich diet with nitrate was incubated in simulated saliva, gastric juice, kale juice, and its ascorbate and methanol soluble portions (5, 10, 15 and 30 mL) for 1 hr at 37$^{\circ}C$ and N-nitrosodimethylamine (NDMA) was detected in the digestion sample, Kale juice and its ascorbate and methanol soluble portions at 30mL inhibited NDMA formation by 60.1$\pm$4.4%, 49.3$\pm$1.2% and 50.1$\pm$2.0%, respectively. The methanol soluble portion was further fractionated by preparative-LC (prep-LC). Nitrite-scavenging effects of 7 methanol soluble portion (Kl, K2, K3, K4, K5, K6 and K7) in kale juice were 2.0 ~56.2%. Among seven fractions, K3, K4, K5 and K7 exhibited weakly on nitrite scavenging effect. Fraction Kl and K2 inhibited NDMA formation by 71.0 and 65.5%, respectively. Fraction Kl and K2 was further separated by prep-LC into 6 subfractions (Kla, Klb, Klc, K2a, K2b and 2nc). Those subfractions inhibited NDMA formation by 40.9 ~80.4%. The K2a subfraction was screened by MS, $^1$H-NMR, $^{13}$ C-NMR and DEPT spectrum.

There has been increasing research interests that green vegetables play beneficial roles in human health. This study was performed to investigate the effects of freeze-dried green vegetable extract of Angelica keiskei Koidz (A) and Brassica oleracea acephala (B) on lipid profiles and antioxidant status in rats. Seven-weeks old male Sprague Dawley rats were divided into 6 groups and fed diets containing 5% A & B and 0.5% cholesterol (cho) for 8 weeks [Control Diet (C) & C + chol (CC), A & A + chol (AC), B & B + chol (BC)]. Lipid profiles and antioxidant status were determined by enzyme assay methods. The serum levels of [LDL + VLDLJ-cholesterol of the rats fed vegetable extract diets A and B were significantly lower than that of group C and the ratios of HDL/[LDL + VLDL] were significantly higher in groups A and B. Addition of cholesterol in the diet, however, abolished this effect. The Brassica oleracea acephala juice lowered serum TG level even when cholesterol was added to the diet. Serum total antioxidant status(TAS) were significantly higher in groups A and B as compared to the control group and the ratios of [GSH-Px +Catalase]/total-SOD in the liver were also significantly higher in groups A and B indicating that H202 produced be efficiently removed. In conclusion, freeze-dried green vegetable extract diets (A and B) improved serum lipid profiles by increasing the HDL/[LDL + VLDL〕 ratio and exerted favorable influences on antioxidant systems by improving total antioxidant status (TAS) in serum and by significantly increasing the ratio of [GSH-Px + Catalase]/total-SOD in the liver.

Objective : The aim of this study was to take a census of elementary school children who have atopic dermatitis(AD) especially the residents of Je-Cheon. Method : We conducted a questionnaire survey of the elementary school children in Je-Cheon who have atopic dermatitis. 96 patients with AD were involved in the survey. The questionnaire was made up of their family history, past history, weaning food, breast-fed or not, dietary treatment and Children's Dermatology Life Quality Index(CDLQI), etc. The student's T-test was used for statistical analysis. Results : Parents and siblings brothers and sisters past history has an effect on patients with AD. With regard to past history of patients, allergic rhinitis was the most common ailment. Formula feeding was common in the group under 6 months of age and the mean age of the start of weaning was 7.25 months. Fruit juice and weaning food of powder type were the first weaning foods in this study. Many parents introduced a grain diet, live diet, bone - soup, egg, milk, cheese and bean curd to their children under 12 months of age. A restricted diet was the most common dietary treatment method in this study. The highest scoring question for CDLQI was itching; the lowest one was related to bullying. Conclusion : We analyzed the patients' family history, past history, weaning food, dietary treatment and Children's Dermatology Life Quality Index(CDLQI), etc. Through this survey, we better understand the actual conditions of elementary school children who had AD in Je-Cheon.
