This study was designed to identify the severity of anorexia and the diet patterns in receiving chemotherapy. The identification of anorexia would provide useful and basic information to oncology nursing care. The subjects of this study were 102 hospitalized chemotherapy patients in a September 10, 1994. The subjects were 20 years old or above and who agreed to participate in this study and could understand the questionnaire. Three-days diet history were collected and analysed. The study subjects change, food aversions, the severity of anorexia. Data related to demographic and other mecdical characteristics such as age, diagnosis, and medication were collected by review of patient medical record. The results of this study were summarized as follows : 1) The score of anorexia was 73.7 in Anorexia Visual Analogue Scales and mean amount of fool intake per a day was 823cc. The larger the anorexia VAS score, the more severe of anorexia. 2) The food preferences of subjects were identified. Those were aversions, or dislikes the meat such as beef, pork, and chicken, and greesy or fried foods. The Caffeinated drinks such as coffee and tea were disgusted, also. The patients preferred vegetables and Korean traditional food especially kimchee and soy bean soap. 3) Those who were administered analgesics and cisplatin suffered more severe in anorexia than those who analgesics and cisplatin was not administarted. The patients with gastrointestinal cancer has more severe anorexia than those who have the other site cancer ; head and neck, genirourinary etc. The result of this study in turn provide valuable nursing practice guidelines for nutritional counseling in cancer chemotherapy patient. Nurses working with chemotherapy ward should identify the severity of anorexia and diet patterns. In conclusion, the severity of anorexia in cancer chemotherapy patients is very important problems. Health care personnels recognize the potential problems of anorexia and encourage the nutritional counseling in cancer chemotherapy patients.

Addition of the treated dietary fiber sources to wheat flour were generally decreased at Amylograph viscosity as the mixing ratio increased. Addition of the treated dietary fiber sources on the preparation of noodles increased weight and volume of cooked noodles but decreased extention force as the mixing ratio increased. The sensory test of the dietary fiber sources mixed noodles supplemented by treated soymilk residue 5% was excellent sensual properties. The properties of the dietary fiber sources mixed noodles supplemented by treated soymilk residue 10% and treated apple pomace 5% were nearly the same in the texture organoleptic properties compared with those of wheat flour noodle.

Dietary data of 538 middle school students have been analysed to identify the contribution of specific foods to absolute intake and between-person-variance in nutrient consumption. The 24-hour-dietary-recall method had been used to collect the data required. Contribution of specific foods, in terms of ranking order for both absolute intake and between-person-variance have been observed. Ranking order of food for absolute intake was given based on the percen of contribution whereas the ranking order of foods for between-person-variance was given based on the percent of contribution whereas the ranking order of foods for between-person-variance was given based on a coefficient fo variation. As a result, for most of the nutrients(except cholesterol), the ranking order of foods for the between-person-variance was quite different from that of absolute intake. The results indicate that to identify between-person-variance of nutrient intake in an epidemiology study, foods with a high ranking in between-person-variance should be included in developing the food frequency questionnaires rather than foods which showed a high ranking in absolute intake.

Capsaicin (8-methyl-N-vanillyl-6-nonenamide: CAP) is a mai or ingredient of hot pepper that has been used as a spicy food additive, preservative, and medicine. In this study, we evaluated the effect of dietary CAP on the selected proto-oncogene(c-jun, c-myc, H-ras, erbB, p53) expressions in various tissues of mice. Male ICR mice were divided into four groups and fed the experimental diets containing CAP at the levels of 0, 5, 20 and 100ppm for four weeks. Steady state RNA levels in various tissues were measured by slot blot hybridization assay. C-jun expression level was enhanced in stomach tissue from mice fed 20ppm CAP and significantly reduced from mice fed 100ppm CAP. The c-jun expression levels were differentially altered in organ-specific manner, Tumor suppressor gene p53 expression level appeared to be slightly increased in the liver from mice fed 20ppm CAP. These results suggested that dietary CAP differentially modulates c-jun and p53 expression in various organs.

The study was performed to investigate the effect of corn bran as a fiber source on the utilization of thiamin niacin and pantothenic acid in human subjects for 8 weeks. Four different corn bran diets were fed : dry milled fine(DF) dry milled coarse(DC) wet milled fine(WF) and wet milled coarse(WC) Basal diet no corn bran bread added was employed as a control Apparent recovery of each B complex vitamin in urine was estimated to evaluate the vitamin and compared. The utilziation of three B vitamins was affected by the corn bran treatment. Dry milled corn bran had a higher recovery rate of thiamin(dry milled : 233% wet milled : 1.70%) than those receiving wet milled corn bran. Similar recovery pattern of niacin(dry milled : 1.94% wet milled : 1.50%) to that of thiamin was also observed. Particle size seemed to affect the vitamin utilization regardless of type of corn bran. Coarse bran gave a lower recovery value than fine corn bran in genreral. For pantothenic acid the recovery of the vitamin was affected to a greater extent by particle size of corn bran than by type of corn bran milling(fine: 60.22% coarse : 51.51%) Groups consuming wet milled corn bran\ulcorner(5`.57%) excreted more NDF than those fed dry milled corn bran(42.29%) Dry milled corn bran showed little or no water holding capacity poor fecal bulking properties and increased fecal transit time. The results suggest that corn bran supplementation exerts an negative effect on three B vitamin utilization.

The effects of chemical compositions (protein, lipid, and dietary fiber) on the physical properties of dried biji powders were investigated. The raw biji was freeze-dried (control) and hot-air dried (untreated). The untreated biji was further defatted and deproteinated. The prepared biji powders were analyzed for the proximate composition, total dietary fiber (TDF), water absorption index (WAI), water solubility index (WSI), swelling power, solubility (including the quantification of soluble carbohydrate and protein fractions), and final viscosity (using a rapid visco analyzer). Control and untreated biji powders exhibited the similar chemical compositions. The defatted biji possessed higher TDF, although its protein content did not significantly differ for control and untreated ones. The deproteinated biji consisted mainly of TDF. WAI and swelling power increased in the order: deproteinated > defatted > control > untreated biji powders. WSI and solubility increased in the order: control > untreated > defatted > deproteinated biji powders. The similar patterns were observed for soluble carbohydrate and protein fractions. The deproteinated biji revealed the highest viscosity over applied temperatures, while the untreated one was lowest. Overall results suggested that the physical properties of the dried biji powder were reduced by protein and fat, but enhanced by dietary fiber.

Data are limited on biological mechanisms underlying the associations of sleep insufficiency with obesity and dyslipidemia. To explore these mechanisms, we investigated appetite-regulating hormones, stress-related hormones, and cardiometabolic indicators in association with sleep fragmentation, which is a type of sleep disorder. In an experimental study, we randomly allocated 40 Wistar male rats aged 7 weeks into four groups; rats with ad libitum sleep and ad libitum intake (Control), those exposed to sleep fragmentation (SF), those with diet restriction (DR), and those exposed to sleep fragmentation and diet restriction (SF+DR). Amongst them, 13-day chronic sleep fragmentation was applied to the SF and SF+DR groups while 50% reduction in chow intake was applied to the DR and SF+DR groups for 13 days. After these experiments, blood lipid and lipoprotein profiles, leptin, ghrelin, adiponectin, cortisol, epinephrine, and norepinephrine levels were compared among the four groups. In the results, the SF group showed the highest levels of serum ghrelin (P<0.001) and the lowest levels of serum adiponectin (P<0.01). All experimental groups showed higher levels of low density lipoprotein-cholesterol (LDL-C) than the Control (P<0.001). LDL-C levels and the ratio of LDL-C and high density lipoprotein-cholesterol were positively correlated with ghrelin levels (P<0.05) in the SF group, but not in the DR and SF+DR groups. In the SF group, the highest levels of serum free fatty acids were also observed and correlated with lower levels of serum adiponectin, which reflects insulin resistance (P<0.05). Based on these findings, we suggest that chronic sleep fragmentation may induce disturbances in lipid metabolism and appetite-regulating hormones independent of food intake, and these metabolic disturbances may be worse due to insulin resistance related to overeating, which is indicated by elevated ghrelin levels in sleep fragmentation. For persons with sleep insufficiency, anti-atherogenic dietary interventions may be recommended to prevent cardiovascular disease.
