This study was peformed to investigate the effect of dietary iron and exercise on heme biosynthesis and lipid metabolism of rats. Rats were divided into 4 groups according to dietary iron supplement (Fe-,5 ppm vs. Fe+, 50 ppm) and exercise status (control us exercise). The experiment continued for 8 weeks. Regular treadmill exercise ($6^{\circ}$, 28 m/min, 30 min duration, 5 days/week) was given to exercise groups. The aminolevulinate dehydrase activity of red blood cell, the marker of heme biosynthesis, was significantly increased in the exercise group. Regular aerobic exercise reduced body weight and epidydimal fat pad gain. Regular exercise also significantly decreased the plasma triglyceride, cholesterol and HDL-cholesterol of the rats. Meanwhile, the iron deficiency decreased the hematocrit and hemoglobin concentration and increased the accumulation of liver cholesterol.

This study was designed to observe the nutritional effects of mugwort powder in albino rats. Forty eight young male albino rats, Sprague-Dawley strain, body weight of $80{\pm}3g$ were employed in the study. They were fed on the basal diets supplemented with 0,2,4,6, and 10% mugwort powder for 4 weeks respectively. The amounts of food and protein intake in animal groups of 4 to 8% mugwder supplemented were higher than that of control group. The efficiencies of food and protein in animal groups of mugwort powder supplemented were lower than that of nonsupplemented group. The animal group of 4% mugwort powder supplemented group was highest in energy intake among of other groups. The growing rate of animal groups of 2-6% mugwort powder supplemented groups were similar to that of the control group where as 8% or more of mugwort powder supplemented groups were below than the control group. The contents of hemoglobin and hematocrit were no remarkable difference among of the all groups. The levels of blood sugar in the groups of 8% and 10% mugwort powder supplemented were significantly higher than that of the control group, but their A/G ratio of the serum protein were significantly lower than that of the control group instead.

Purpose: The purpose of this study was to investigate diabetic knowledge, self-care behaviors, and HbA1c of patients with diabetic mellitus in public hospitals. Methods: Participants were 287 adult patients who had been diagnosed with diabetes in two public hospitals in Seoul. Collected data were analyzed using t-test, ANOVA, Pearson's correlation with the SPSS (PASW) 21.0 program. Results: For general characteristics of the participants, there were significant differences in the level of diabetic knowledge according to age (F=11.28, p<.001), educational level (F=11.07, p<.001), type of health insurance (F=9.38, p<.001), and monthly income (t=-4.58, p<.001) and in the self-care behaviors according to age (F=8.61, p<.001) and in HbA1c according to age (F=6.72, p=.001). As for disease related characteristics of the participants, significant differences were found for self-care behaviors according to education about diabetes (t=3.90, p<.001) and in HbA1c according to education about diabetes (t=3.26, p=.001) and current diabetic therapy methods (F=13.51, p<.001). The study results showed that there was no correlation between diabetic knowledge and self-care behavior, or between self-care behavior and HbA1c. Conclusion: Results indicate that when developing preliminary data on nursing intervention education programs on diabetes, increasing diabetic knowledge and self-care behaviors would help to improve blood glucose levels.

Purpose: This study used raw data from the fifth (2010-2012) Korea National Health and Nutrition Examination Survey (KNHANES) to assess the relationship between vitamin D level and glycemic control of diabetes, and to provide basic data about the use of vitamin D for preparation of a treatment plan for diabetes in South Korea. Methods: For this study, data of 1,713 diabetes from KNHANES (2010-2012) were used. The collected data were analyzed using SPSS 18.0 program, and complex sample frequency analysis, descriptive statistics, complex sample cross analysis, complex sample general linear regression, and complex sample logistic regression analysis were performed. Results: It was found that the poor glycemic control group among the diabetes subjects had significantly lower level of blood vitamin D than the good glycemic control group. Factors affecting glycemic control included drinking, vitamin D levels, hypertriglyceridemia, duration of diabetes, and treatment of diabetes. Also, diabetics with vitamin D deficiency or shortage showed 3.55- and 2.61-times higher odds ratios, respectively, to be diagnosed as the poor glycemic control group than diabetics without vitamin D deficiency or shortage. Conclusion: This study is significant because it provides rationale and basic data about the use of vitamin D for preparation of a treatment plan for diabetes in South Korea by assessing the dependence of glycemic control on the vitamin D level of diabetics. Additionally, future studies are necessary to determine the appropriate concentration of vitamin D for diabetes prevention and treatment to prevent the side effects of excessive supplementation.

The congenital deformities of cleft lip and cleft palate have been known to afflict man since prehistoric time. Efforts to correct these abnormities have evolved over the centuries as scientific knowledge has advanced. Although there is no agreement as to when the surgery should be performed, most surgeons adhere to "rule of 10" : the infant must be 10 week old weigh 10 Ibs, have a hemoglobin value 10gm/dl and have a white blood cell count no greater than 10 $thousands/mm^3$. Consensus favors performing initial palatal surgery in the child when he is between 18 and 24 months old. The timing of cleft alveolus surgery is usually between 10 and 11 years old. In the period from 1992 to 1996, 38 patients with cleft lip and cleft palate treated at the department of oral and maxillofacial surgery, Chosun university, dental hospital were analysed clinically. The obtained results were as follows. 1. The ratio of male to female was 1.92 : 1 (25/23) 2. The ratio of cleft lip, cleft palate and cleft lip & palate was 1.5 : 1 : 2.5 (12/8/18) 3. The ratio of unilateral to bilateral cleft lip was 5 : 1 (25/5) 4. The ratio of left to right side in unilateral cleft lip was 1.5 : 1 (15/10)

A 6-week feeding trial was conducted to determine the nutritional value of various dietary animal protein sources in juvenile Koran rockfish. White fish meal (WFM), flounder muscle meal (FMM), blood meal (BM), casein & gelain (CG), egg white albumin (EWA) and squid liver powder (SLP) were used as the animal protein sources, Crude protein content and available energy of the experimental diets were 50% and 15.9 kJ/g, respectively. There were significant differences among all dietary groups in weight gain (WG), feed efficiency (FE), and protein effiency ratio (PER). WFM and FFM were the best animal protein sources among the dietary groups. FMM diet had significantly higher (P<0.05) WG, FE, and PER values than those of fish fed the WFM diet. WG, FE, PER, and specific growth rate (SGR) values of fish fed BM diet were significantly higher (P<0.05) than those of fish fed EWA diet. Significant differences were found in whole body composition, hemoglobin (Hb), hepatosomatic index (HSI), and hematocrit (Ht). These results showed that low-temperature processing of lyophilized flounder muscle meal resulted in superior performance of rockfish relative to the other evaluated animal protein sources.

Objectives: The purpose of this study is to identify prevalence and related factors of the elderly, who took health examination, with metabolic syndrome. Methods: The health examination and lifestyle survey were performed for 21,512 adults at 60 years of age or older who took health examination in H health promotion center during January-March 2009. Results: The prevalence of metabolic syndrome for the subject was 24.0%. Of the subject with metabolic syndrome, the prevalence of the diseases was obesity 60%, abdominal obesity 78.5%, hypertension 82.6%, dyslipidemia 89.7% and diabetes 51.9%. In comparison of the relationship between metabolic syndrome and other diseases, the male subject with metabolic syndrome were significantly higher in BMI, waist circumference, systolic/diastolic blood pressure, hemoglobin, AST, ALT, $\gamma$-GTP, TG, AC glucose, creatinine than normal male(p<0.001). In comparison of the relationship between metabolic syndrome and lifestyle, more drinking frequency and amount in male and more drinking frequency in female were associated with increased risk of metabolic syndrome(p<0.01). Regardless of exercise intensity, practice of exercise contributed to reduce the risk of metabolic syndrome(p<0.01). Conclusion: In conclusion, TLC program, focused on lifestyle behaviors which is strongly associated with the prevalence of metabolic syndrome, should be developed for the improvement of life quality in the elderly with metabolic syndrome.

This study was designed to evaluate Saturday nutrition classes for obese elementary students in Chungnam Province. Obesity index, nutrient intake, nutrition knowledge, nutrition attitude, and self-satisfaction of 36 obese elementary students were compared before and after attending nutrition classes every other Saturday for 3 months. The average age, height, weight, body fat, % body fat, and obesity index were 11.9 years, 145.5 cm, 53.3 kg, 24.5 kg, 45.7%, and 32.4%, respectively. Most of the subjects(94.5%) viewed themselves as fat. Sixty-three percent of children were discontent with their body-image. All answered that they have experience with weight control. The major methods of weight control were exercise and reduction of snacks. The mean serum cholesterol, blood glucose, GOT/GPT, and hemoglobin were 177.4 mg/dL, 90.4 mg/dL, 25.8/25.5 IU/L, 14.5 g/dL, respectively. After attending nutrition classes, the daily intakes of energy, plant protein, plant fat, carbohydrate, crude fiber, and cholesterol increased significantly. The scores for nutrition knowledge, nutrition attitude, and self-satisfaction also increased after nutrition classes, but there were no significant differences. Percent body fat decreased significantly after nutrition classes. In conclusion, nutrition education for elementary students is effective for the prevention and control of obesity. Further research is needed to develop a systematic program of nutrition education for obese children.

Two types of diets, extruded pellet (EP) and raw-fish-based moist pellet (MP) were fed to compare growth, water quality and histology of olive flounder, Paralichthys olivaceus in Jeju fish farm. Two groups of 7000 fish per each tank (initial mean weight 51 g) were fed one of two diets for 7 months. At the end of the feeding trial, significant differences were found in weight gain and feed utilization. Dissolved oxygen (DO) level of the MP tank was decreased from 7.98 to 6.89 after feeding. There were no significant differences in hematocrit, hemoglobin, alanine aminotransferase and aspartate aminotransferase of fish fed the two diets. Whole body protein content of fish fed the EP was significantly higher than that of fish fed the MP. While the feeding rate by month indicated numerically decreased, fish fed the MP had higher feed intake than that of fish fed the EP. Histological examination of hepatopancreas, kidney, and anterior intestine of fish fed the EP did not show any negative effects compared to those of fish fed the MP. This study revealed that EP could substitute for MP in terms of growth performance, blood parameters, water quality and histology of olive flounder.

The disease occurred in cultured eel (Anguilla japonica) in a recirculatory culture system without any separated filtration apparatus. As the pond had a high level of nitrite with $60mg/{\ell}$, 1% NaCl was added to reduce nitrite toxicity to eel. The first outbreak was observed a week after the NaCl treatment and continued for 10 days. Accumulated mortality was about 0.2-0.5%. Affected fish ranged from 150-350 g were usually anorexic and exhibited yellow colour in the skin of the abdominal region and at the base of pectoral fins, as well as in the eyes. In a few individuals with severe symptoms, the lateral skin was also yellowish. The spleen, kidney, muscle and gall bladder were yellowish and the liver was pale-yellow colour but green on the posterior part. The gall bladder was shrunken without bile. Some abnormal erythrocytes such as "tear drop" cells (dacrocyte) were observed in peripheral blood smears stained with May-Grunwald Giemsa. Hematocrit values and hemoglobin contents in the jaundiced eel were significantly lower compared with apparently heathy eel. Severe haemosiderosis accompanied by erythrophagocytosis was found in the kidney and spleen. Haemosiderin deposits were observed in macrophages of the haematopoietic tissue of the kidney and in the splenocytes. But no significant alterations were found in the hepatic cells. In this study we report the first outbreak of jaundice in cultured eel in Korea. Pathological and hematological investigations suggested that severe hemolysis may resulted in jaundice in eel although the cause of hemolytic jaundice was not identified in this study.
