In a 12-week experiment, the rock bream, Oplegnathus fasciatus, and olive flounder, Paralichthys olivaceus, were investigated to determine the effects of starvation on their physiological parameters. The protein and DNA contents of the starved fish were significantly higher than the initial values and those of the fed fish. The RNA contents and RNA/DNA ratios of the fed fish were significantly higher than those of the other groups (P<0.05). The hematocrit, hemoglobin, red blood cells (RBC), and mean corpuscular volume (MCV) of the fed rock bream were significantly higher than at baseline (P<0.05), whereas the mean corpuscular hemoglobin concentration (MCHC) of the fed fish was lower than at baseline (P<0.05). The hematocrit, hemoglobin, RBC, and MCHC of the starved group were significantly lower than the baseline values, whereas the MCV of the starved group was significantly higher than the baseline value (P<0.05). No significant difference in alanine aminotransferase was observed between the fed fish and baseline, whereas the starved fish value was significantly higher than the baseline value (P>0.05). There were no significant differences in cortisol levels. However, the glucose level in the fed group was significantly higher than the baseline level and that in the starved group was significantly lower than the baseline level (P<0.05).

This study was designed to assess the iron nutritional status and anemia of middle school girls in Ulsan City, who were evaluated with a questionnaire, measurement of hematological indices. The average height and weight of respondents were 154.81$\pm$6.28cm and 48.51$\pm$8.80kg, respectively. Mean daily energy intake was 1815.72$\pm$328.04kcal and iron intake was 15.13$\pm$4.50mg. The average hemoglobin concentration of subjects was 11.98$\pm$0.78g/dl, and the average hematocrit level was 36.62$\pm$2.21%. Transferrin saturationTS (%) was 25.58$\pm$9.82%, and the ferritin level was 40.45$\pm$23.03ng/ml. Iron deficiency anemia among the subjects was estimated as 54.2% by using hemoglobin(<12g/이), 33.9% by hematocrit (<36%). The clinical symptoms relating anemia were measured with 4 Likert scale (1 : never, 4 : often), 'tired out easily (2.34$\pm$0.92)' was the highest, followed by 'feel dizzy always (2.26$\pm$0.85)', 'decreasing ability to concentrate (2.23$\pm$0.77)', 'get a cold easily (2.19$\pm$0.82)', 'have a headache (2.10$\pm$0.79)', 'poor memory (2.09$\pm$0.83)', 'no appetite (1.99$\pm$0.85)', As for the correlation between iron parameter and clinical symptoms related to anemia, the hematocrit rate was negatively correlated with 'get a cold easily', 'pale face', 'feeling blue', 'difficult digestion' (p<0.05). The level of iron was negatively correlated with 'tired out easily', 'get a cold easily' (p<0.05) and TS (%) were negatively correlated with 'tired out easily (p<0.05)', 'get a cold easily (p<0.01). Our study resulted that the prevalence of a iron deficiency of a middle school girl is very high, therefore the guidelines for iron supplementation and nutritional education to improve their iron status should be provided.

Purpose: This study was to identify the effect of the experience of diabetes education on knowledge, self-care behavior and glycosylated hemoglobin (HbA1C). Further, this study was held to examine about patient's preferred methods of education and re-education frequency. Methods: 166 type 2 diabetes patients from two hospitals in Incheon participated in this study. Data were analyzed by using descriptive analysis, t-test, ANOVA, Scheffe's test and multiple regression analysis. Results: 72.3% patients needed re-education and the average interval of re-education was 8.53 months. Patients preferred education methods were lectures, practical training, and studying from pamphlet. Depending on the frequency of diabetes education, there were significant differences in the level of diabetes knowledge (F=10.88, p<.001) and self-care behaviors (F=4.59, p=.012), but there was not significant difference with HbA1C (F=1.53, p=.220). As to how much the diabetes education helped managing diabetes, there was a significant difference in the level of self-care behaviors (t=2.01, p=.049), but there were not significant differences in level of knowledge (t=1.10, p=.275) and HbA1C (t=-.33, p=.746). The experience of diabetes education was a significant factor which influenced patient's knowledge (t=3.93, p<.001) and self-care behaviors (t=2.21, p<.001). But HbA1C was not influenced by the experience of diabetes education (t=-1.68, p=.096). Conclusion: It is necessary to provide diabetes education with appropriate interval and methods and subjects that reflect the needs of patient through the study results.

A study was carried out to investigate the dietary environment food intake and blood picture of rural housewives. Sixty percent of female farmer's was in weak health state. Mean farmer's syndrome score was 4, 7 which meaning that they must give attention to their health. The intake of animal food group was poor Most of nutrients taken by them were almost lower than those of Korean Recommended Dietary Allowances except vitamin C. According to the blood tests the blood levels of lipids calcium magnesium iron hemoglobin and hematocrit were in lower states. All of the farmers were lower serum level of ferritin whereas but glucose protein and albumin levels were normal. Serum magnesium was correlated with cereal intake The intake of cereal fat and oils and vegetables was correlated with physical perfect index. Hemoglobin and hematocrit level were negatively correlated with physical perfect index. Hemoglobin and hematocrit level were negatively correlated with the food group of fruits and fishes.

Purpose: We investigated whether the white blood cell (WBC) count to hemoglobin (Hgb) level ratio is correlated with the presence of cortical defects on dimercaptosuccinic acid (DMSA) renal scan in children with febrile urinary tract infection (UTI). Methods: We examined 95 children who were consecutively admitted to our hospital with their first episode of febrile UTI. Blood tests (C-reactive protein [CRP], WBC, Hgb] were performed. All enrolled children underwent DMSA scanning during admission. Data were compared between children with positive and negative DMSA results. The correlations between WBC to Hgb ratio and the presence of cortical defects on DMSA scan, and between WBC to Hgb ratio and CRP level were analyzed using the Pearson chi-squared test. Multiple logistic regression analysis was used to evaluate whether WBC to Hgb ratio could predict the cortical defects on DMSA scan in children with febrile UTI. Results: The WBC to Hgb ratio was significantly higher in children with positive DMSA results than in those with negative DMSA results; positively correlated with the presence of cortical defects on DMSA scan and CRP; and was a significant factor for predicting the presence of cortical defects on DMSA scan. Conclusion: The WBC to Hgb ratio may predict the presence of cortical defects on acute DMSA scans in children with febrile UTI.

This study was carried out to investigate the supplementary effects of ${\gamma}$-oryzanol on the blood glucose level in diabetic mice. We supplied 2 experimental diets (CO without and GO with 0.2% ${\gamma}$-oryzanol) to diabetic mice for 8 weeks. Diet intake, body weight and levels of blood glucose, hemoglobin $A_{lc}$ and insulin were measured. Though there was no significant difference in diet intake between experimental groups, the concentration of fasting blood glucose and blood glucose area from glucose tolerance test in diabetic mice was lower in GO group than CO group during the supplementary period of experimental diets. Hemoglobin Ai, was lower and serum insulin level was higher in GO group than CO group without significance. These results suggest that r-oryzanol decrease the blood glucose level, and ${\gamma}$ -oryzanol produced from residual product of rice may be developed with high value.

Objectives : Anemia is a common problem in the management of elderly patients. Recent studies reported that anemia was associated with cognitive impairment and Alzheimer's disease. This study was aimed to analyze the differences of hemoglobin levels in Korean patients with Alzheimer's disease(AD) dementia, mild cognitive impairment(MCI), and healthy controls. Furthermore, the study also examined if any association between hemoglobin levels and cognitive functions existed. Methods : A total of 116 Korean elderly adults were participated in this study(mean age 74.67 years ; 60.3% female). The Korean version of the Mini-Mental State Examination(MMSE-K), Clinical Dementia Rating(CDR) and Global Deterioration Scale(GDS) were applied to all subjects. Hematological and related blood chemistry values were investigated. Results : We found that patients with AD dementia had significantly lower hemoglobin and hematocrit levels than MCI subjects and healthy control group. The hemoglobin levels showed a positive correlation with MMSE-K and negative correlation with CDR, GDS. Conclusions : Among Korean elderly, low hemoglobin level is associated with a cognitive impairment. This study indicates that AD is associated with anemia, and low hemoglobin levels may contribute to potentially useful clinical markers of AD. The risk factor for dementia needs to be confirmed by prospective longitudinal studies in a larger group of patients.

The purpose of this study was to evaluate the significance of higher than normal mean corpuscular volume (MCV) and lower than normal mean corpuscular hemoglobin concentration (MCHC) in 20 patients. The hemoglobin (Hb), red blood cell indices (MCV, MCH, MCHC,), red cell distribution width (RDW), serum ferritin, serum iron (Fe) and total iron binding capacity (TIBC) were measured and the transferrin saturation were calculated. 18 (90.0%) cases were categorized as chronic diseases. Chronic renal failure, malignancy, and bleeding were all related to the cases. The mean values of hemoglobin was $9.5{\pm}2.14g/dL$; the MCV was $29.0{\pm}2.8fL$; the MCH was $30.9{\pm}1.0pg$; the MCHC was $31.2{\pm}0.5%$; the RDW was $17.0{\pm}3.6%$; serum Fe was $39{\pm}21{\mu}g/dL$; the TIBC was $219.7{\pm}108.8{\mu}g/dL$; transferrin saturation was $19.2{\pm}9.9%$ and ferritin was $445.5{\pm}499.6{\mu}g/L$ in the patients. The WHO criteria for hemoglobin of patients confirms anemia in 18 of the 20 (90.0%) cases. Anemia of chronic disease was shown in 11 (73.3%) cases; acute gastric ulcer with hemorrhage in 1 (6.7%) case; iron deficiency anemia in 1 (6.7%) case; 2 patients (13.3%) were of normal cases. There were changes in the baseline Hb level results of the 19 (95.0%) cases while no change was shown in 1 case. As a result, diseases associated with anemia and bleeding where the MCV is higher than the normal range and MCHC is lower than normal range are considered relevant findings.

This study was conducted to evaluate the effects of lead on the incidence of anemia and to find cases with lead poisoning early among female workers who have been exposed to lead occupationally, for one year from August, 1985. The level of blood lead and hemoglobin concentration were observed for 284 female lead workers and 123 female non-lead workers of industries in the Gumi industrial complex in Kyungpook Province. The average age was $20.3{\pm}2.9$years and $21.1{\pm}3.5$ years in lead workers and non-lead workers, respectively. The average working duration was $26.46{\pm}19.26$ months in lead workers. The mean value of blood lead was $30.11{\pm}6.61{\mu}g/100ml$ and $21.86{\pm}3.75{\mu}g/100ml$ in lead workers and non-lead workers, respectively. There were significant differences between two groups. The mean value of hemoglobin concentration was $14.00{\pm}0.57g/100ml$ and $14.03{\pm}0.64g/100ml$ in lead workers and non-lead workers, respectively. Anemia cases were not observed at Hb concentration below 12g/100ml. The percentages of lead workers at Hb concentration ranged 12.0~13.0g/100ml were 4.5%. There was no dose-response relationship between blood lead level and the incidence of anemia. There were no remarkable differences between age and blood lead level as well as Hb concentration, and between working duration and the level of blood lead and hemoglobin.

Protein malnutrition of children is one of the most serious nutritional deficiencies in developing country. Urea nitrogen excretion in ureotelic animals is the function most sensitive to dietary protein. The 24 hours excretion of creatinine in the urine of a given subject is remarkably constant from day to day. The creatinine excretion of different individuals of the same age and sex is also quite constant. Low ratios of urinary urea to creatinine are found children low protein intake. The foregiving world-wide investigations indicate that the urea nitrogen/creatinine ratios seems to be a good biochemical indicator to distinguish among group with different levels of protein intake. The purpose of this study is to evluate an indicator of protein intake on the elementary school children ranged from 6 to 8 years of age living in rural and urban areas. Each child measured for height and weight of body. weight measured by means of a plate from scale and height by a vertical measuring rod. Biochemical test were taken from a finger-tip and urine. Hemoglobin level in the blood was measured by cyanomethemoglobin method. From the urine samples, urea nitrogen and urea creatinie were determined by Folin-Wu method and: calculate the ratio. The following result were obtained: 1) Mean of the body weight and height in urban children(Seoul) was higher and heavier than rural children(Kyunggi, Kangwon). And 12% of boys, 18% of girls in Kyunggi and 25% of boys, 22% of girls in Kangwon area weight less than 80% of Korean Physical Standard weight level. 2) The mean hemoglobin values of boys and girls in Seoul are children were 13. 3g/100ml, 13.1g/100ml and the mean of hemoglobin values in Kyunggi 12.9g/100ml of boys, 12.4g/100ml of girls, and 12.4g/100ml of boys, 12.9g/100ml of girls in Kangwon children. It is found that 22% to 24% children inrural area (Kyunggi, Kangwon) had hemoglobin level less than 12g/100ml which means anemia. 3) The mean of hematocrit level of Seoul, boys and girls children were 33.5%, 34.1% and 33.4%, 33.1%, in Kyunggi area and 33.1%, 32.9% in Kangwon area. 4) Urea nitrogen/creatinine ratios in Seoul children were 9. 0, 10. 0 of boys and girls, the ratio were 8.2, 8.0 in Kyunggi boys and girls children, and 7.5 and 7.4 in Kangwon boys, girls children. Low-income rural and upper-income urban background large differences between two groups in the urea nitrogen/creatinine ratio(Seoul: Kangwon in male, female children. p<0.05, p<0.001). The urea nitrogen/creatinine ratio definetly seems to be a good indicator of the quantity of the protein intake. However, whether or not it is an indicator of the quality of the ingested protein ramains to be seen.
