The purpose of this study was to evaluate a nutrition education program designed to reduce sugar intake in preschool children. The nutritional knowledge, dietary attitude, dietary behavior, and food intake with a sweet taste in preschool children were tested before and after 4 weeks of nutrition education from March 8 to April 1, 2016. The preschool children were recruited in Dobong-gu, Seoul. The subjects were divided into two groups; educated (N=59) and non-educated group (N=40). Statistical analyseis were performed using SPSS 22. The nutritional knowledge about sweet tasting food was significantly increased (P<0.01) in the educated group and significantly decreased (P<0.01) in the non-educated group. The dietary attitude toward sweet tasting food was significantly decreased (P<0.05) in the educated group but not significantly changed in the non-educated group. The dietary behavior toward sweet tasting food was significantly decreased (P<0.05) in the educated group and significantly decreased (P<0.01) in the non-educated group. The major food sources of sugar intake were not significantly changed in either groups. The major food sources of sugar intake in the 5 years old children were yogurt products>sweetened breads>cookies/biscuits>chocolate>cereals>beverages>sweetened milk>sweet spicy chicken>Tteokbokki. Although there are some limitations in this study, due to the short length of the nutrition education and lack of active participation by the parents, the results suggest that effective nutrition education on sweet tasting food can bring about changes in nutritional knowledge as well as dietary attitude.

BACKGROUND: Autoimmune hemolytic anemias are characterized by autoantibodies recognizing antigens on the Individual's own red blood cells, resulting in immune- mediated hemolysis. Blood transfusions have been regarded as hazardous in patients with autoimmune hemolytic anemia (AIHA) because of potential intensification of hemolysis and a presumed high incidence of alloimmunization. METHODS: We examined the pretransfusion and posttransfusion hemoglobin levels in 6 patients with autoantibodies in their sera, which showed panagglutinations with all bloods tested in the compatibility testing. They received 'least' incompatible blood because of inability to find compatible blood. RESULTS: When we compared pretransfusion hemoglobin level with posttransfusion hemoglobin level, in 5 of 6 patients with AIHA, the hemoglobin levels were increased after red cell transfusion. 4 patient who did not respond to transfusion therapy initially had an increase in hemoglobin level after steroid treatment. Any signs or symptoms indicating hemolytic transfusion reaction were not observed ducting the transfusion period in all patients. CONCLUSIONS: The decision to transfuse in AIHA should consider multiple factors including the patient's clinical status, the potential benefit of transfusion, the potential response to other therapeutic modalities, but must never be regarded as contraindicated, even though the compatibility test may be strongly incompatible.

The purpose of this study was to establish the selection of indicators for estimating and factors affecting the requirement of vitamin B6. There has been a need to establish the human requirements of vitamin B6 since vitamin B6 is thought to be involved in more than one hundred biochemical reactions as a coenzyme in the metabolism of amino acids, glucose, and lipid, and the synthesis of neurotransmitters. For the review of the literature, this study included from early findings of the sixties to studies of 2009. This study suggests that plasma pyridoxal 5' phosphate (PLP) is the best single indicator of vitamin B6 status for the healthy but not for the non-healthy. Erythrocyte aspartate aminotransferase and alanine aminotransferase activation by PLP as an indirect measure and urinary 4-pyridoxic acid excretion as a direct measure are useful as supporting indicators. Bioavailability, nutrient interaction, physiological need, and chronic diseases may increase the requirement for vitamin B6. However, these effects can not be quantified due to insufficient evidences.

Picky eating behavior is a significant factor in causing unhealthy eating and disturbing the growth of children. This study examined picky eating behaviors and food intake of 112 preschoolers aged 3∼5 year, picky eaters (n=41) and non-picky eaters (n=71), living in Dobong-gu, Seoul metropolitan area, South Korea.Picky eating questionnaires and three consecutive 24-hour dietary recalls were collected from their caregivers.The difference between the two groups was verified using a Chi-square test or t-test and Pearson’s correlation. Compared to the non-picky eaters, fussiness, satiety responsiveness, and refusal of food variety were significantly higher in picky eaters (P＜0.001). Compared to the non-picky eaters, an assessnent of the preschooler’s behavior and the caregivers’ perception were positively correlated in picky eaters (r=0.749, P＜0.001). The intakes of shellfish (P＜0.05), vegetables (P＜0.001), fiber, vitamin E (P＜0.01), vitamin A, and folate (P＜0.05) were significantly lower in picky eaters than the non-picky eaters. The major food sources of vitamin A and folate were vegetables, of which grains were the source of fiber, fats and oils were the source of Vitamin E, and root vegetables were source of vegetables in both picky and non-picky eaters. In conclusion, picky eating behaviors are related to different fussiness and slowness in eating. Therefore, it is suggested to increase the amount of meal and vegetable intake in picky eaters.

BACKGROUND/OBJECTIVES: The purposes of the study were to investigate folate intakes and plasma folate concentrations as well as estimate folate status in Korean healthy adults. SUBJECTS/METHODS: A total of 254 healthy 19- to 64-year-old adults (68 men and 186 women) living in Seoul metropolitan area, Gumi, and Kwangju, Korea participated. Three consecutive 24-hour dietary recalls, information on folate supplementation, and fasting blood samples were collected from the subjects. RESULTS: The mean dietary folate intakes were 587.4 and 499.2 µg dietary folate equivalent (DFE)/day for men and women, respectively. The median dietary intakes of men and women were 566.6 and 474.6 µg DFE/day, respectively. Forty subjects (16.7% of total) less total folate than the estimated average requirement (EAR). Folate intakes of 23.3% of men and 34.8% of women aged 19–29 years did not meet the EAR for folate. Major food sources consumed for dietary folate were baechukimchi (Chinese cabbage kimchi), rice, spinach, eggs, and laver, which provided 44% of dietary folate intake for the subjects. Plasma folate concentrations were 23.4 nmol/L for men and 28.3 nmol/L for women, and this level was significantly lower in men than in women. Approximately 13% of men and 3% of women were folate-deficient, and the percentages of subjects showing folate concentrations lower than 10 nmol/L were 27.9% of men and 6.4% of women. CONCLUSIONS: Folate intakes of Korean adults in this study were generally adequate. However, one-third of young adults had inadequate folate intakes.

This study investigated the effect of physical training and oxidative stress on the antioxidative activity and on plasma lipid profile. Forty eight rats were given either a physical training or no training for 4 weeks and were then subdivided into 3 groups: before-exercise (BE); during-exercise (DE); after-exercise (AE). The antioxidative activity was evaluated with the activities of catalase in plasma and superoxide dismutase (SOD), the ratio of reduced glutathione/oxidized glutathione (GSH/GSSG) and the level of malondialdehyde (MDA) in liver. The plasma concentrations of triglyceride (TG), total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C)) were also compared. Compared to those of non-training group, catalase activities of training group were lower before exercise but higher during and after exercise. SOD activities were higher regardless of exercise. GSH/GSSG ratio was higher before exercise but was not significantly different during exercise and even lower after exercise. There were no differences between non-training group and training group in MDA levels regardless of exercise. Compared to those of non-training group, atherosclerotic index of training group was lower after exercise and there were no significant differences before and during exercise. There were no differences between non-training group and training group in HDL-C regardless of exercise. These results suggest that moderate physical training can activate antioxidant defenses and decrease the atherosclerotic index and this beneficial effect is evident under exercise-induced oxidative stress.

Phospholipase C (PLC) plays a pivotal role in transmembrane signal transduction pathway for cellular proliferation differentiation and growth. Thus far, there have been few reports in which PLC activity was investigated in human malignant neoplastic tissues. In the present study, we evaluated PLC activity in 23 human gastric cancer tissues and normal mucosal tissues to investigate whether alteration of PLC activity is associated with gastric cancer. The amount of [14C] diacylglycerol, one of the earliest products of inositol phospholipid hydrolysis by PLC, was measured by thin layer chromatography. Also, expression of PLC-gamma1, which is one of the most important PLC isozymes,was examined by immunohistochemistry using specific monoclonal antibody directed against PLC-gamma1. The results are summarized as follows. PLC activity in all 23 gastric cancer tissues (1.35+/-1.04 units/mg of protein) was significantly higher than normal mucosal tissues (0.28+/-0.21 units/mg of protein) (P<0.001). PLC activity in gastric cancer tissues was not correlated with histologic grade (P>0.05). PLC-gamma1 immunoreactivity was detected in all of 23 cases studied. The intensity and extent of PLC-gamma1 immunoreactivity was not correlated with PLC enzyme activity, although stronger intensity was demonstrated in malignant cells in comparison to normal gland epithelial cells. The present study provides the first evidence of significant elevation of PLC activity in human stomach cancer tissues. Our results strongly suggest that PLC might be involved in tumorigenesis and/or progression(uncontrolled continuous cycling of cells) of human gastric cancer. Further studies are needed to elucidate the role of elevated PLC activity in cancer tissues.
