Purpose : Allergic proctocolitis is a major cause of bloody stool in early infancy. This study was aimed at ascertaining the clinical courses, sigmoidoscopic and histologic findings of allergic proctocolitis. We also analyzed the relationship between peripheral eosinophilia, the age at symptom onset, and sigmoidoscopic and histologic findings. Methods : We reviewed 25 infants retrospectively who had sigmoidoscopy and biopsy performed with a clinical diagnosis of allergic proctocolitis from April 2003 to April 2007. Results : The mean age at symptom onset was $15.2{\pm}13.2$ weeks. Fourteen infants (56.0%) were breast fed, one (4.0%) was formula fed, six (24.0%) were on combined formula, and four (16.0%) were on a weaning diet. Peripheral eosinophilia (${\geq}250/mm^3$) was seen in eighteen infants (75.0%), but total serum IgE was increased only in six (24.0%). Sigmoidoscopic findings were variable from normal (8.0%), erythema or edema (20.0%), lymphoid hyperplasia (8.0%), erosion (12.0%), hemorrhage and ulcer (4.0%) to lymphoid hyperplasia with erosion, hemorrhage, or ulcer (48.0%). Histologic findings showed focal infiltration of eosinophils in lamina propria (96.0%) and crypt epithelium (96.0%). In twenty four infants (96.0%), the number of eosinophils in mucosa was increased by a more than 60/10 high power field. There was a negative correlation between peripheral eosinophilia and the age at symptom onset. Among the twelve breast fed infants, bloody stool disappeared in ten (83.0%) with a maternal elimination diet of major food groups, but two improved spontaneously. Conclusion : Allergic proctocolitis should be considered as one of the major causes of bloody stool in healthy appearing infants. To confirm the diagnosis it is necessary to perform sigmoidoscopy and biopsy but histologic findings are more informative than sigmoidoscopic findings. Peripheral eosinophilia was prominent in the infants with an early onset of symptoms. Most infants experienced benign courses and recovered with the elimination of causative foods but did not need exclusive food restrictions.

The effects of protein-bound polysaccharides (A-PBP and L-PBP) that were extracted from the mycelia of two edible mushrooms, namely Agaricus blazai and Lentinus edodes, on serum cholesterol and body weight were investigated in mice and female volunteers. Six groups of Male Balb/c mice were fed six kinds of diet supplement- solutions composed of L-PBP, A-PBP, chitosan, and other fiber constituents, for 30 days under the normal diet. Ninety female volunteers were also supplemented for 8 weeks with six kinds of capsules including control and five test groups as the same manners (two times a day, 4 capsules). From 12 days after feeding of L-PBP (Group I) and A-PBP (Group II), the weight of mice began to reduce as compared with control, whereas that of Group III fed chitosan was decreased 15 days after feeding. Group W and Group V which were fed mixture of L-PBP, A-PBP, chitosan, and other dietary fiber, were more significant in lowering weight. After 4 weeks of the supplementation in women, their serum LDL-cholesterol level and body weights in Group I and II were reduced, but Croup 111 taken with chitosan capsule showed weaker effect than Group I and II. After 8 weeks, LDL-cholesterol content in the sera of Group I (132.5 mg/dL) and II(131.5 mg/dL) was decreased to ideal level (125.4 and 122.8 mg/dL) for healthy blood vessel. In the case of Group W supplemented with mixture of L-PBP, A-PBP, and chitosan, the weight-reduction effect (11.8%) and hypocholesterolemic effect (11.0%) was most significant, indicating their synergistic action. These data suggested that the weight-controlling and hypolipidemic effect of L-PBP and A-PBP was involved, at least in part, in absorption of cholesterol as their role of dietary fiber, as well as cholesterol metabolism.

Objective: This study was performed to identify associations between the practice of health behaviors and awareness of metabolic syndrome (MetS) among adults aged 19 to 64 years in the Gwangju-Jeonnam area. Methods: This study utilized data from the 2010 Community Health Survey (CHS). Health behaviors considered in this study were smoking, alcohol drinking, physical activity, low-salt diet, and perception of stress. The index for the health behaviors was calculated as the sum of the practice of each health behavior (range: 0-5). The analysis was weighted with a complex sampling design, and the chi-square test and multiple logistic regression analysis were used to identify the association between the practice of health behaviors and awareness of MetS. Results: A total of 19.8% of the population were aware of MetS. The perception of MetS was statistically significantly associated with healthy behaviors, including nonsmoking (aOR = 1.33, 95% CI = 1.14-1.56), non-high-risk drinking (aOR = 1.54, 95% CI = 1.27-1.88), engagement in physical activity (aOR = 1.48, 95% CI = 1.28-1.72), and a low-salt diet (aOR = 1.30, 95% CI = 1.13-1.51). The ORs of the perception of MetS were significantly higher in patients with a health behavior index of 2 to 3 (aOR = 1.64, 95% CI = 1.01-2.66) and in those with an index of ${\geq}4$ (aOR = 2.47, 95% CI = 1.51-4.04) than in those with an index of 0. Among all health behaviors, physical activity had the highest OR for the perception of MetS (aOR = 1.50, 95% CI = 1.29-1.74). Conclusions: This study revealed associations between health behaviors, especially physical activity, and awareness of MetS. Therefore, integrated health promotion programs may be needed to enhance awareness of MetS and to effectively prevent MetS and non-communicable diseases.

Objective: In this study, we investigated the adverse effects of dietary zearalenone (ZEA) (0.5 to 1.5 mg/kg diet) on the localization and expression of the growth hormone receptor (GHR) in the uteri of post-weaning gilts and explored alternative mechanism of the reproductive toxicity of ZEA on piglets. Methods: A total of forty healthy piglets (Duroc${\times}$Landrace${\times}$Large White) aged 28 d were selected for study. Piglets were transferred to single cages after 10 days' adaptation on an obstetric table. The animals were allocated to one of four treatments: a normal basal diet supplemented with 0 (Control), 0.5 (ZEA0.5), 1.0 (ZEA1.0), or 1.5 (ZEA1.5) mg/kg purified ZEA, and fed for 35 d after the 10-d adaptation. Analyzed ZEA concentrations in the diets were 0, $0.52{\pm}0.07$, $1.04{\pm}0.03$, and $1.51{\pm}0.13mg/kg$, respectively. At the end of the feeding trial, piglets were euthanized after being fasted for 12 h. Two samples of uterine tissue from each pig were rapidly collected, one of which was stored at $-80^{\circ}C$ for analysis of the relative mRNA and protein expression of GHR, and the second was promptly fixed in Bouin's solution for immunohistochemical analysis. Results: The relative weight of the uteri and thickness of the myometrium and endometrium increased linearly (p<0.001) and quadratically (p<0.001) with an increasing level of ZEA. The results of immunohistochemical analysis indicated that GHR immunoreactive substance was mainly localizated in the cytoplasm of uterine smooth muscle, glandular epithelial, luminal epithelial, stromal, and vascular endothelial cells. In contrast, nuclear staining was rarely observed. The immunoreactive integrated optic density of GHR in the myometrium, luminal epithelium, glandular epithelium, and whole uteri of weaning gilts increased linearly (p<0.001) and quadratically (p<0.05) with an increasing level of ZEA. The mRNA and protein expression of GHR in the uteri of weaning gilts increased linearly (p<0.001) and quadratically (p<0.05) with an increasing level of ZEA. Conclusion: In conclusion, ZEA at a concentration of 0.5 mg/kg was sufficient to significantly thicken the myometrium and endometrium, and at a concentration of 1.0 mg/kg induced a high level of GHR expression to promote growth and development of the uteri. This revealed an alternative molecular mechanism whereby ZEA induces growth and development of the uteri and provides a theoretical basis for the revision of Chinese feed hygiene standards.

This study was designed to investigate the effect of supplementation of fish oil on serum apoprotein and platelet function in healthy young females. Eighteen female college students were divided into 3 groups. Each group fed a typical Korean diet supplemented with 15g, 12g, and 9g of fish oil respectively for 1-week. Blood samples were obtained 4 times, before supplementation, immediately after, 1-week after and 3-week after stopping supplementation. After 6-week break, the doses of fish oil were interchanged among 3 groups and the experiment was repeated to reduce interindividual variation. The concentration of apoprotein A, apoprotein B in the serum samples and the platelet adhesion, the platelet aggregation and bleeding time were determined immediately after supplementation of fish oil, 1-week after and 3-week after stopping supplementation and then the value compared with those of before supplementation period. The results obtained are summarized as follows: Serum apoprotein A levels decreased significantly(p<0.05), immediately after supplementation of fish oil in the 15g group. The serum apoprotein B levels did not show significant change. The platelet adhesion decreased significantly(p<0.05) 1-week after supplementation of fish oil in the 15g group. The platelet aggregation decreased significantly(p<0.01) immedeately after supplementation of fish oil in the 15g group.

The effect of kimchi pill supplementation on plasma lipid concentration of middle aged healthy people were studied. Freeze-dried mustard leaf added (30%) Korean cabbage kimchi and powdered glutinous parch were used to prepare kimchi and placebo pill, respectively. Experimental group if six participants took 3 g of freeze-dried kimchi as a pill daily for 6 weeks which is equivalent to 30 g of fresh kimchi and control group of six people took same amount of placebo. The diet intakes for the kimchi and placebo group fairly remained unchanged during 6 weeks of trial. When the effect of kimchi pill supplementation was expressed as average percentage changes based on each individual changes, the plasma triglyceride concentration of kimchi pill group was sig-nificantly decreased by 16.8% during trial (p<0.05)while that of placebo group increased by 9.8%, But no changes in plasma and LDL cholesterol concentrations of both groups were observed. HDL cholesterol of kimchi pill group significantly increased by 11.7%(p<0.05), therefore the ratio LDL/HDL cholesterol was significantly decreased by 6.7%(p<0.05) while that for the placebo group increased. The atherogenic index at the kimchi group was also significantly decreased by 10.8%(p<0.05). Kimchi supplementation seemed to have beneficial effects on controlling plasma triglyceride and HDL cholesterol in middle aged men.

This study was conducted to determine riboflavin status of young healthy Korean women. Eight subjects consumed general Korean diet for 3 weeks. Riboflavin intake was measured during the period and Erythrocyte Glutathione Reductase Activity coefficient (EGRAC) was analyzed at the end of experimental period. The subjects who showed EGRAC value above 1.20 were supplemented 6 mg riboflavin per day for 1 week. The average age of subjects was 22.1 years old, height was 154.4cm, weight was 49.2kg, chest circumference was 81.2cm, the sum of skinfold thickness of 3 parts was 79.5mm and Body Mass Index(BMI) was 20.6. Hemoglobin concentration was 13.0g/100ml, hematocrit value was 44.0% A/G ratio was 1.4, and the activity of sGOT, sGPT, alkaline phosphatase was 14.3, 11.0 and 6.5, respectively. The average daily intake of energy, protein and riboflavin was 1745kcal, 56.1g and 1.14mg, respectively. The mjor source of riboflavin were milk, egg, Korean cabbage, rice, beef and so on. The average EGRAC value was 1.2748. percentages of subjects who showed EGRAC value above 1.20 was 65.2%. After oral administration of 6mg riboflavin, the EGRAC value of all these subjects was returned to normal range. Riboflavin intake was correlated positively with energy as well as protein intake, and correlated negatively with EGRAC value. However, riboflavin intake per 1,000kcal was not correlated with EGRAC value.

Purpose Glomerular filtration rate(GFR) is an important indicator for the diagnosis, treatment, and follow-up of kidney disease and is also used by healthy individuals for drug use and evaluating kidney function in donors. The gold standard method of the GFR test is to measure by continuously injecting the inulin which is extrinsic marker, but it takes a long time and the test method is complicated. so, the method of measuring the serum concentration of creatinine is used. Estimated glomerular filtration rate (eGFR) is used instead. However, creatinine is known to be affected by age, gender, muscle mass, etc. eGFR formulas that are currently used include the Cockroft-Gault formula, the modification of diet in renal disease (MDRD) formula, and the chronic kidney disease epidemilogy collaboration (CKD-EPI) formula for adults. For children, the Schwartz formula is used. Measurement of GFR using ⁵¹Cr-EDTA (diethylenetriamine tetraacetic acid), ^99mTc-DTPA (diethylenetriamine pentaacetic acid) can replace inulin and is currently in use. Therefore, We compared the GFR measured using ^99mTc-DTPA with the eGFR using CKD-EPI formula. Materials and Methods For 200 kidney transplant donors who visited Asan medical center.(96 males, 104 females, 47.3 years ± 12.7 years old) GFR was measured using plasma(Two-plasma-sample-method, TPSM) obtained by intravenous administration of ^99mTc-DTPA(0.5mCi, 18.5 MBq). eGFR was derived using CKD-EPI formula based on serum creatinine concentration. Results GFR average measured using ^99mTc-DTPA for 200 kidney transplant donors is 97.27±19.46(ml/min/1.73m²), and the eGFR average value using the CKD-EPI formula is 96.84±17.74(ml/min/1.73m²), The concentration of serum creatinine is 0.84±0.39(mg/dL). Regression formula of ^99mTc-DTPA GFR for serum creatinine-based eGFR was Y = 0.5073X + 48.186, and the correlation coefficient was 0.698 (P<0.01). Difference (%) was 1.52±18.28. Conclusion The correlation coefficient between the ^99mTc-DTPA and the eGFR derived on serum creatinine concentration was confirmed to be moderate. This is estimated that eGFR is affected by external factors such as age, gender, and muscle mass and use of formulas made for kidney disease patients. By using ^99mTc-DTPA, we can provide reliable GFR results, which is used for diagnosis, treatment and observation of kidney disease, and kidney evaluation of kidney transplant patients.

In oder to study the correlation between daily urinary output of sodium chloride and blood pressure, twenty four hour urine samples were collected from 224 cases (70 male and 154 female) of healthy Koreans whose age varied from 18 to 70 years old. The volume and concentration of sodium, chloride and potassium and total nitrogen were measured, along with the resting blood pressure. Results obtained are summarized as follows; 1. Daily urinary output was increased as a function of age. However, daily urinary output per unit sulface area was maintained at approximately 800 to 900 $ml/m^2$ in all age groups of male and it increased as a function of age in female groups. There was no significant difference between male and female. 2. The daily urinary sodium concentration was decreased gradually acceding to age in both sexes. Daily excretion of sodium was constant regardless of age in both sexes but especially high in 25-39 year female age group, which was slightly greater in males than in females. 3. The daily urinary chloride concentration was at approximately 250 meq/L in all age groups of male and which decreased as a function of age in females. 4. Hence the daily urinary output of sodium chloride was constant in all age groups of males which increased as a function of age in female groups. However, daily excretion of sodium chloride per unit sulface area was maintained at approximately 11 $gm/m^2$ in males and which increased as a function of age in females. 5. The daily urinary excretion of potassium was constant regardless of age in both sexes. 6. Urinary K/Na ratio was maintained at approximately 0.27 in males and 0.33 in females. 7. The daily urinary output of total nitrogen amount was approximately $8{\sim}10$ gm in males and $7{\sim}9$ gm in females. However, daily urinary output of nitrogen per unit sulface area was constant regardless of age in both sexes. 8. The systolic blood pressure was increased gradually according to the age in both sexes and was higher for males than females under 40 years of age. However, there was no significant difference between both sexes in ages over 40 years. 9. Quantitative comparisons indicated that daily urinary output and sodium chloride excretion are higher while daily potassium output, nitrogen excretion and urinary K/Na ratio are significantly lower among Koreans than a among Occidentals. These findings suggest that average Koreans live on low-protein and high-salt diet throughout their livers. Statistical result obtained may he summarized as follows; 10. The relation between blood pressure and sodium concentration of urine. The correlation between systolic blood pressure and sodium concentration was negatively associated for both sexes and the correlation coefficient was significant for females $({\gamma}_1=-.19<-{\gamma}_{152},\;_{0.05}=-0.159)$ and it was not significant for males $({\gamma}_1=-.19>-{\gamma}_{68},\;_{0.05}=-0.232)$ tut may be due to the sample size for males. The correlation between diastolic blood Pressure and sodium concentration was negatively associated for both sexes and the correlation coefficient was significant for males $({\gamma}_1=-.37<-{\gamma}_{68},\;0.05=-0.232)$ and the relation was not significant for females $({\gamma}_1=-.11>-{\gamma}_{152},\;_{0.05}=-0.159)$. 11. The relation between blood pressure and daily urinary sodium chloride excretion. The association between systolic blood pressure and sodium chloride excretion was positively correlated for both sexes and the relation was significant for females $({\gamma}_1=.20>{\gamma}_{152},\;_{0.05}= 0.159)$ and it was insignificant for males $({\gamma}_1=.09<{\gamma}_{68},\;_{0.05}=0.232)$, The relation between diastolic blood pressure and sodium chloride excretion was positively associated and insignificant for both sexes males $({\gamma}_1=.17<{\gamma}_{68},\;_{0.05}=0.232)$ and females $({\gamma}_1=.09<{\gamma}_{152},\;_{0.05}=0. 159)$. 12. The relation between daily urinary nitrogen excretion and sodium chloride excretion. The association between daily nitrogen excretion and sodium chloride excretion was positively significant for both sexes, males $({\gamma}_1=.31>{\gamma}\;_{68},\;_{0.05}=0.232)$ and females $({\gamma}_1=.36>{\gamma}_{-152},\;_{0.05}=0.159)$.
