This experiment was carried out to find out the effect of piglet anemia prevention of the chelated iron with amino acids fed to the sows during the late gestation and early lactation as compared with oral iron administration, intramuscular iron-dextran injection and control (receiving no iron supplement) groups. Twenty crossbred sows (Landrace ${\times}$ Large White) bred purebred Large White boars were used to evaluate four treatments. The results obtained in this experiment were as follows: 1. There were no significant differences among the average body weights at birth in all the treatment groups. But the average body weight at 15 days of age was heaviest in the chelated iron group. At 35 days of age, the control group was lightest in the treatment groups. 2. The survival rates at weaning were not recognized significantly among all the treatment groups. 3. At birth and 15 days of age, the levels of hemoglobin, red blood cell and hematocrit of the chelated iron group were higher (P<.05) than those of the control group. But at 35 days of age, they were not recognized significantly.

Purpose: We have preoperatively and postoperatively investigated the characteristics of anemia in patients with gastric cancer in order to provide optimal medical care for the patients. Materials and Methods: Preoperative hemoglobin, serum iron, serum ferritin, serum vitamin $B_{12}$, and serum folic acid were measured for 321 patients with gastric cancer. These were measured again for 287 patients 6 months postoperatively. Results: Ninety-four patients (29.3%) had preoperative anemia. Preoperative hemoglobin, serum iron, and serum vitamin $B_{12}$ levels were higher in the patients with early gastric cancer than in patients with advanced gastric cancer. Preoperative hemoglobin, serum iron, and serum ferritin levels were higher in male patients than in female patients. The patients who had preoperative anemia showed a high probability of having postoperative anemia (P<0.001), and the patients who had low serum ferritin levels preoperatively showed a high probability of having low serum ferritin levels and iron deficiency anemia postoperatively (P<0.004). Conclusion: Preoperative ferritin deficiency should be improved by iron supplement, even though the patient may not be anemic at that time. Periodic postoperative measurements of the hemoglobin, serum iron, serum ferritin, serum vitamin $B_{12}$, and serum folic acid levels are highly recommended because postgastrectomy anemia is not rare. Finally, if any low hemoglobin, serum iron, serum ferritin, serum vitamin $B_{12}$, or serum folic acid levels are found, they should be treated in an appropriate way.

In Korea, delivery of preterm has increased gradually, preterm delivery rate was 6.4% in 1995 and 9.8% in 2002. The purpose of this study is to provide guidelines for preventing preterm delivery in aspect of health factors and food habits. The health factors and dietary habits were compared between preterm delivery group and full-term delivery group on to recognize risk factor of delivering premature. The results obtained are summarized as follows. The full-term delivery group showed a high rate of professionals and the preterm delivery group showed a high rate of the service industry, showing differences in kinds of occupation(p<0.05). Heights were higher in full-term delivery group(p<0.05). Among the nutrition supplements, iron supplement consumption was the most, period of the intake of iron was significantly longer for the full-term delivery group than for the preterm delivery group(p<0.05). Also, prevalence of coffee was higher in preterm delivery group(p<0.001). The activity level was higher in full-term delivery group(p<0.005).

Purpose: Despite the popularity of dietary supplements, little data are available on their use by university students. The purpose of this study was to examine the use of vitamin mineral supplements and to identify factors related to supplement use among university students. Methods: University students (N = 345) in Seoul were surveyed. Survey questions included descriptive demographics, types of vitamin and mineral supplements used, health related lifestyle factors, mini dietary assessment, and knowledge and behaviors related to supplement use. Results: Of university students surveyed, 41% consumed vitamin and mineral supplements. Among the supplement users, multivitamins were the most commonly used dietary supplements (68.6%), followed by vitamin C (31.4%) and calcium (17.1%). In particular, the use of vitamin C and iron supplements was more common in females than males (p < 0.05). For the number of supplements taken daily, 32.1% of supplement users consumed 2 or more supplements; 20% of supplement users had almost no knowledge of the supplements being taken. Based on the results of multivariable logistic regression analysis, supplement use was associated with higher interest in their own health, non-smoker, and supplement use by family (p < 0.05). In addition, supplement use was slightly associated with healthy dietary behavior such as consuming a variety of foods (p = 0.05) and current disease status (p = 0.05). Conclusion: University students with relatively healthy lifestyles appear to take vitamin and mineral supplements, but they had little knowledge of the supplements. Given high prevalence of dietary supplement use among university students, nutrition education regarding supplement use is needed.

Maternal stress was very common symptom that every pregnant women could have experienced during pregnant period. We found that the causative factors of stress for subjects were physical change(50.8%), family relationship(13.6%), change of body image(7.4%), concern baby(6.8%), economic difficulties(6.4%), depress(4.3%), morning sickness(3%), and miscellaneous(3.5%). According to our study, maternal stress during the first trimester negatively correlated with food and nutrients intake of pregnant women and gave low weight gain during pregnancy and low birth weight of infants. It also significantly correlated with monthly income(p<0.001) and monthly food cost(p<0.001) during pregnant period. Mean intake of Calcium and Iron were $47{\sim}60%$ of RDA and $35{\sim}48$ of RDA, respectively. With the Iron supplement the total intake of Iron exceeded 100% of RDA. We also found majority of food items, except seaweeds, fruits and vegetables, were negatively correlated with maternal stress during three trimesters. Additional support system projected by professionals in health-care field could mediate maternal stress and lead to healthy pregnancy outcome.

This study was conducted to evaluate the effects of dietary supplementation of catechins and wheat bran on growth performance, carcass characteristics and meat color using forty-eight Hanwoo steers. Each steer was randomly assigned to one of four treatments. Treatments were as follows: control, catechins, wheat bran, and catechins+wheat bran (CW). At the end of the feeding trial, blood samples were collected for analysis of hemoglobin and iron concentration, and then steers were slaughtered at a commercial abattoir. Catechins, wheat bran, and CW had no effect on growth performance and carcass characteristics. Percentage of myoglobin in M. longissimus dorsi was not affected by treatments. Percentage of oxymyoglobin was increased (p<0.05) by CW and maintained at the highest level (p<0.05) for CW during meat display time up to 24 h. Percentage of metmyoglobin was the lowest (p<0.05) for CW between 5 and 24 h during display time. Although blood iron concentration was not affected by treatments, total concentration of muscle iron was the lowest (p<0.05) for CW compared with that of other treatments. Therefore, the results of the present study suggest that CW may provide good protection against oxidation of myoglobin, and might be an effective dietary supplement for improving meat color in the late fattening period of Hanwoo steers.

The objective of this research was to evaluate the immune response to Salmonella Gallinarum experimentally infected layers fed with Guanosine 5'-monophosphate-chelated calcium and iron feed additives. Hy-Line brown, 34 week-olds layers were assigned to 3 groups; Group 1: basal diet feed, Group 2 (CaFe-GMP): basal diet feed mixed with chelated calcium and iron, and Group 3 (Fe-OCHT): basal diet feed mixed with chitosan for 4 weeks. There were challenged with 1.0×10⁸ CFU/mL of the cultured Salmonella Gallinarum (SG) by oral administration on 28th feeding days. After SG challenge, Flow cytometric profiles showed that the CD4+/CD8+ T lymphocyte activation of Group 2 was much higher than Group 1 and Group 3 (P<0.05). In addition, the levels of interleukin-2 (13.37 mg/dl) and interferon-γ (2.35 mg/dl) in Group 2 were higher than Group 1 and Group 2. Populations of Lactic acid bacteria (3.5×10¹⁰ CFU/g) from cecum was highest observed in group 2. Re-isolation of SG from cecum in group 2 (8×10⁵ CFU/g) was lower than group 1 (1.83×10¹⁰ CFU/g). The result of this study demonstrated that CaFe-GMP feed additive may be one of the potential candidates to control salmonellosis and functional feeds in layers.

In order to assess the effect of feeding raw or processed cotton (Gossypium) seed meal (CSM) on meat and wool production, 30 male crossbred lambs (3-4 months) of uniform body weight were assigned equally to five dietary treatments in a completely randomised design. The CSM was processed by three different methods i.e., cooking the meal at $100^{\circ}C$ for 45 minutes, treatment with 1% calcium hydroxide ($Ca(OH)_2$) for 24 h and iron treatment in the ratio of 1 part free gossypol (FG) to 0.3 parts of iron for 30 minutes. The lambs were fed isonitrogenous and isocaloric concentrate mixtures, containing 30% deoiled peanut meal (reference diet) and 40% of either raw, cooked, $Ca(OH)_2$ or iron treated CSM for 180 days. The raw and variously processed CSM replaced about 50% nitrogen of reference concentrate mixture. The concentrate mixtures were fed to meet 80% of the protein requirements (NRC, 1985) along with ad libitum chopped maize (Zea mays) hay. The slaughter weight, empty body weight and carcass weight was higher ($p{\leq}0.01$) in lambs fed cooked CSM incorporated diets, compared to diets containing deoiled peanut meal (DPNM). These parameters were not influenced by feeding diets containing either raw, $Ca(OH)_2$ or iron treated CSM in comparison DPNM diets. The carcass length, loin eye area and edible and inedible portion of carcass and the meat: bone ratio in whole carcass were also not affected by feeding CSM based diets. Among various primal cuts, the yield of legs was lower ($p{\leq}0.05$) from raw CSM fed lambs in comparison to DPNM fed lambs. The fat content in the Longissimus dorsi muscle was reduced ($p{\leq}0.05$) in lambs fed processed CSM based diets compared to those fed DPNM diet. Replacing DPNM with either raw or processed CSM based diets did not influence the sensory attributes and overall acceptability of meat. The wool yield was higher ($p{\leq}0.05$) in iron treated CSM fed lambs. The fibre length and fibre diameter were comparable among lambs on various dietary regimes. Among lambs fed variously processed CSM diets, the feed cost per kg of edible meat production was lower ($p{\leq}0.05$) on $Ca(OH)_2$ treated CSM, followed by cooked CSM diet and then on raw CSM based diets compared to DPNM diet. The CSM after 1% $Ca(OH)_2$ treatment or cooking for 45 minutes appears to be a satisfactory protein supplement in lamb diets for meat and wool production to replace at least 50% nitrogen of scarce and costly peanut meal.

We report a case of 15 year-old Jehovah's Witness patient with mild anemia who underwent a successful orthognathic two-jaw surgery. Jehovah's Witness patients refuse transfusion of blood or blood products even in life threatening situations. The use of recombinant human erythropoietin and iron supplement increased hemoglobin during preoperative period. Intraoperatively, meticulous surgical hemostasis, acute normovolemic hemodilution and induced hypotension enabled the completion of the operation without the use of blood products.

Following the previous report (Part I: For Sea-divers and Hwa-Jeon-Min) authers have conducted another nutrition survey for Buddhists (male and female) in a temple 'Soo Duk Sa' locating in ChungNam province. The following results were obtained: 1. Cereals, green vegetables and potatoes were staple foods for the Buddhists (male and female) and no any animal foods were eaten by them during the survey period. 2. Carbohydrate intake was very high and the calorie derived from it occupied approximately 80% of tatal calorie intaken. 3. All the nutrients except carotene, niacin and iron are low in their amounts of intake. Especially, protein and riboflavin intakes are low. 4. Buddhists are prohibited to eat animal foods. Therefore, nutrition education and guidance are needed for them to supplement the protein and some other problems.
