Purpose: The purpose of this study was to determine the efficacy of early low-dose iron supplementation in term breast-fed infants. Methods: Eighty-seven healthy term infants were divided into 3 groups: A, formula-fed; B, breast-fed only; S, breast-fed with iron supplementation (5 mg/day from 2 months of age). We measured ferritin, iron, total iron binding capacity (TIBC), transferrin saturation rate (TFSAT), hemoglobin (Hb), hematocrit (Hct), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and red cell distribution width (RDW) at birth, 6 months of age, and 12 months of age. Results: 1) At 6 months of age, ferritin, iron, TFSAT, and Hb in Group B were the lowest among the 3 groups, whereas TIBC and RDW were the highest. The incidences of iron deficiency (ID) and iron deficiency anemia (IDA) in Group B were 33% and 30%, respectively, significantly higher than those seen in Groups A (5% and 8%, respectively) and S (7% and 5%, respectively). 2) At 12 months of age, ferritin, TFSAT, Hb, MCV, and MCH in Group B were the lowest among the 3 groups, whereas TIBC and RDW were the highest. Iron and Hct did not differ among the 3 groups. The incidences of ID and IDA in Group B were 64% and 50%, respectively, again significantly higher than those seen in Groups A (4% and 3%, respectively) and S (9% and 7%, respectively). Conclusion: The prevalences of ID and IDA were higher in breast-fed infants than in formula-fed infants, even at 6 months of age. Early and low-dose iron supplementation in breast-fed infants improved iron status and lowered the incidence of iron deficiency anemia in early infancy.

Background: China carries a heavy burden of cervical cancer (CC) and substantial disparities exist across regions within the country. In order to reduce regional disparities in CC, the government of China launched the National Cervical Cancer Screening Program in Rural Areas (NCCSPRA) in 2009. Critical to the success of the program are the health care workers who play a pivotal role in preventing and managing CC by encouraging and motivating women to use screening services and by providing identification and treatment services. This study aimed to assess cervical cancer knowledge among these health care workers at the county level in maternal and child health (MCH) hospitals across different socio-economic regions of China. Materials and Methods: A cross-sectional survey was conducted and self-administered questionnaires were sent to all health care workers (a total of 66) providing cervical cancer screening services in 6 county level MCH hospitals in Liaoning, Hubei and Shaanxi provinces, representing eastern, central and western regions of China; 64 (97.0%, 64/66) of the workers responded. ANOVA and Chi-square test were used to compare the knowledge rate and scores in subgroups. Results: The knowledge level of the respondents was generally low. The overall combined knowledge rate was 46.9%. The knowledge rates for risk factors, prevention, clinical symptoms, screening and diagnostic tests and understanding of positive results were 31.3%, 37.5%, 18.1%, 56.3% and 84.4%, respectively. Statistically significant differences in scores or rates of CC knowledge were seen across the different regions. The total and sectional scores in the less developed regions were statistically significantly lower than in the other regions. Conclusions: The majority of the health care workers who provide CC screening service in NCCSPRA at county level MCH hospitals do not have adequately equipped with knowledge about CC. Given the importance of knowledge to the program's success in reducing CC burden in rural women in China, efforts are needed to improve the knowledge of health care workers, especially in less developed regions.

The purpose of this study was to compare nutrient intakes and the serum iron status of 74 Food and Nutrition major, and 45 non-major, female students at a university in Incheon. This cross-sectional survey was conducted using a self-administered questionnaire and the data were analyzed by the SPSS 10.0 program. The nutrient intake data collected from three-day dietary recalls were analyzed by the Computer Aided Nutritional Analysis Program. Anthropometric data and hematological indices of iron in the blood were measured. Average heights, weights, body fat and mid-upper arm circumference of Food and Nutrition major and non-major female students were 160.3 cm, 53.5kg, 25.8%, 23.7cm and 159.8cm, 55.5kg, 28.9%, 24.8cm, respectively. There were significant differences in body fat percentage and mid-upper arm circumference between the major and non-major students. In all subjects, daily dietary intakes of nutrients- except protein, vitarrlin B1, vitamin C and phosphorus - were lower than the Korean RDA. In particular, calcium and iron intakes of all subjects were under 60% of the Korean RDA. Values of RBC (red blood cell) count, Hb (hemoglobin), Hct (hematocrit), MCV (mean cell volume), MCH (mean cell hemoglobin), and MCHC (mean corpuscular hemoglobin concentration) of the non-major students were significantly higher compared to those of the major students. The diastolic blood pressure of the major students was negatively correlated with MCV, MCH, TS, and serum iron levels. Triceps skinfold thickness, mid-upper arm circumference and waist-to-hip ratios of the non-major students were negatively correlated with TIBC. Fat intake was positively correlated with RBC, Hb, Hct, and TIBC (total iron binding capacity) in the major students. Vitamin C intake was positively correlated with serum iron in the major students. Carbohydrate intake was positively correlated with Hb, Hct, and MCHC in the non-major students. Niacin and iron intakes were positively correlated with Hb and Hct in the non-major students. Therefore, nutrition education is necessary for female university students to improve nutritional status and to practice optimal nutrition strategies. (Korean J Nutrition 35(9) : 952~961, 2002)

Purpose: The purpose of this study was to examine the relationship between pigmental reaction and blood components, such as white blood cell (WBC), lymphocyte, monocyte, red blood cell (RBC), hemoglobin, mean corpuscular index (mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC)), hematocrit, platelet and neutrophil segment, after Cupping Glass Therapy (CGT). Subjects: Twenty-five healthy adults participated in this study; Methods: Subjects had undergone CGT for 5 days and were divided into two groups (dark color (DCG) and light color (LCG)) depending the level of pigmental reaction. Blood was collected from each subject at the beginning of this study and recollected after 5 day s'CGT. Results: The percentage of lymphocytes was higher in LCG than in DCG after CGT (p<.01) and was significantly increased in LCD after CGT (p<.01), The number of RBC was more in DCG than in LCG both before (p<.01) and after CGT (p<.05). The amount of hemoglobin was more in DCG than in LCG both before (p<.01) and after CGT (p<.01) and was significantly increased in LCD after CGT (p<.01). Mean corpuscular index showed that both MCH (p<.05) and MCHC (p<.01) were higher in DCG than in LCG after CGT, but only MCHC before CGT (p<.01). It also showed either decreased MCV (p<.01) or increased MCHC in LCD after CGT (p<.01). Hematocrite was higher in DCG than in LCG both before (p<.01) and after CGT (p<.01). The percentage of neutrophil segments was higher in BCG than In LCG after CGT (p<.01) and was significantly decreased in LCD after CGT (p<.05). However, neither the number of WBC and platelets nor the percentage of monocytes was significantly different between DCG and LCG either before or after CGT. Conclusion: Pigmental reaction was significantly related to the changes of blood conponents after CGT. The results of this study suggest that CGT may have an effect on the components of blood cells.

The objective of this study was to investigate the effects of BPA on reproductive characteristic and blood hematological and chemical values in mice. The male mice were intraperitoneally injected BPA in native control(no treatment), positive control(corn oil, 3$m\ell$/kg B.W), 0.05, 0.5 and 5.0mg BPA/kg B.W and female mice were injected BPA in control(corn oil, 3$m\ell$/kg B.W), 0.05, 0.5 and 5.0mg BPA/kg B.W with 5 times at 3 days interval for 14 days. The administration of BPA in male mice didn't affect the body and reproductive organ weight such as testis, epididymis, vesicular gland and coagulating gland. We found that the 5.0mg BPA group was significantly reduced the sperm concentration and increased the sperm abnormality compared to native, positive control and 0.05mg BPA groups(P<0.05), but any other effects were not found in sperm viability and motility in BPA treatment groups. The RBC, HB, HT, MCV, MCH, MCHC, albumin, BUN and total protein of blood hematological and chemical values in male were not different in all experimental groups(P>0.05). However, the value of WBC was slightly lower in BPA treatment groups than that of control groups and PLT was slightly higher in BPA groups than that of control groups, but not significantly defference among the experimental groups(P>0.05). In female mice, the effects of BPA on body weight didn’t affect in all experimental groups, but ovary weights in 0.5 and 5.0mg BPA groups were significantly increased compared to those in control and 0.05mg BPA group(P<0.05). The uterine weight in BPA groups was slightly higher than that of control group, but not significantly different in all experimental groups(P>0.05). The RBC, Hb, HT, MCV, MCH, MCHC, albumin and total protein of blood hematological and chemical values in female were not different in all experimental groups(P>0.05). The values of WBC and PLT in BPA groups were slightly higher than that of control, but not significantly different among the experimental groups. The concentration of BUN was the higher in BPA groups than that of control group. The histological evaluation of testis, ovary and uterus were not different in all experimental groups.

Lead is a ubiquitous environmental and industrial pollutant that causes a major health concerns. It is known to induce a broad range of physiological, biochemical, and behavioral dysfunctions in laboratory and humans, including hematopoietic system, kidneys, liver, and reproductive system. This study was conducted to investigate the effect of Saengshik supplementation on the lead-induced toxicity in rats. Five week old male Sprague­Dawley rats were randomly assigned to five groups for six weeks as followings: control group (CT), lead acetate treated group (PT), and lead acetate groups administered with three different dosages of Saengshik $(SI2.5-12.5\%,\;S25-25\%,\;and\;S50-50\%).$ Lead acetate (12 mg/rat) was intragastrically administered daily for 6 weeks. The results were summarized as follows; Weight gain and food efficiency ratio were significantly lower (p<0.05) in lead administered group compared with those of the control group. Also, significant lead-induced alteration in blood hemoglobin (HGB), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and reticulocyte distribution width (RDW) were observed. In the liver of lead-exposed animals, there was an increase in the lipid peroxidation (MDA) and the level of glutathione (GSH), but superoxiede dismutase (SOD) activity did not change. Lead-exposed animals with $25\%\;and\;50\%$ Saengshik supplementation showed marked improvements in the values of MCH, MCV, and RDW. Also, the level of HCT was significantly increased by $50\%$ Saengshik supplementation. The levels of liver MDA in $12.5\%\;and\;50\%$ Saengshik administered groups and GSH level in $50\%$ Saengshik administered group were significantly decreased compared to the lead administered group. Also, hepatic SOD activity tended to increase in the presence of Saengshik supplementation. Furthermore, the accumulation of lead in liver and kidney was reduced by presence of Saneghshik supplementation. Liver lead concentration was significantly reduced by both $25\%\;and\;50\%$ Saengshik supplementations and kidney lead concentration was significantly reduced by the $25\%$ Saengshik supplementation. These results show that Saengshik may have a protective effect against lead intoxication but the mechanism of their effects remains unclear.
