Cholestatic liver disease is a frequent complication of prolonged parenteral nutrition, especially in premature infants. Numerous factors have been cited as contributing to TPN associated cholestasis. However the exact etiology remains obscure. Ursodeoxycholic acid (UDCA) has been reported to be beneficial far children and adults with various chronic cholestatic liver disease. The aim of this prospective, randomized, double-blind, placebo-controlled study was to determine the preventive effects of UDCA administration during TPN. Seventeen pediatric patients (8 boys and 9 girls) undergoing TPN were assigned randomly to two groups, UDCA and placebo group. UDCA group (n=9) received 15 mg/kg/day UDCA and placebo group (n=8) received 15 mg/kg/day placebo enterally during the TPN period. Liver function tests (total bilirubin, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase) were per-formed before TPN and weekly or three times a week. The patients' weights, complete blood count, composition of TPN, and the infusion rate of TPN and lipid were monitored everyday. Calcium and phosphate were monitored twice a week. Between the UDCA and placebo groups, there were no differences in weight at the onset of TPN, birth weight, duration of TPN, respiratory distress syndrome associated with prematurity, age at the onset of TPN, gestational age, the number of days the patients received antibiotics, the number of patients received enteral nutritions and the composition of TPN. In contrast, there was a significant difference between the UDCA and placebo groups in alanine aminotransferase levels during TPN. It doesn't seem that UDCA administration during TPN correlates directly with improvement of liver function. But the preventive administration of UDCA may be effective in reducing liver enzyme, alanine aminotransferase and has no adverse effects.

This study investigated the utilization of activated calcium (AC) as preservatives for wet noodle manufacturing. The quality characteristics and shelf-life of wet noodle made with sterilized distilled water, 5% alcohol, 0.1% AC plus 5% alcohol, 0.2% AC plus 5% alcohol, and 0.2% AC were evaluated. The total microbial count and pH value of wet noodle were determined during storage at $10^{\circ}C$. During storage at $10^{\circ}C$ for 42 days, pH of wet noodles was slightly decreased with increased storage periods. The pH values of wet noodles made with AC were higher than the others. Instrument textural characteristics (hardness, adhesiveness, springiness, cohesiveness, gumminess, and chewingness) were measured and were not significantly changed during storage period. The total microbial counts in wet noodles increased with extended storage duration. With AC, microbial growth rate were decreased compared to the control for whole storage period. In sensory evaluation, a little difference was shown between control and AC or alcohol containing wet noodles and no significant differences during the storage period. It was concluded that shelf-life of wet noodles was extended two-fold or more by adding AC for storage at $10^{\circ}C$.

This study was to examine the shelf life and qualities of castellas added with mixture of Morus alba root bark (MA), Ecklonia stolonifera (ES), and Curcuma aromatica (CA) extracts (MECE). The result of total microbial cell count showed that castellas with MECE were increasing storage time, especially at the rate of MA : ES : CA=0.75:0.75:0.5, and was reduced about 3 log cycle as compared to that of control. Also castellas with MECE were shown to have the highest antioxidant effect by Rancimat method. In the color, redness of castellas diminished with increasing amounts of MECE in castellas while conversely, lightness and yellowness increased. In sensory evaluation, the castella containing MA 0.25%, ES 0.25% and CA 0.125% were preferred than the control. These results suggest that the addition of MA 0.25%, ES 0.25% and CA 0.125% in castella positively improved the preservation and development of quality.
A Theileria sergenti soluble merozoite preparation containing the 29, 34, 35 and 105 KD as the immunodominant polypeptides, was evaluated for efficacy, safety and protectivity in Holstein calves against virulent field tick challenge. The soluble antigens (100 mg/dose) were fortified with either complete or incomplete Freund's adjuvant. Twenty naive calves, aged one month, were subcutaneously inoculated with the preparation and a booster dose was administered 4 weeks later. Twenty additional calves served as controls. Five weeks after the booster dose, vaccinates and uninoculated controls were moved to a pasture, a heavily tick infested area in Cheju-do, Korea. The vaccinates showed negligible change in hematocrit and total RBC count whereas control animals showed significant (p<0.05) hematological changes and associated anemia. Only 30% of vaccinates required chemotherapy after the experiment was terminated. All control animals required chemotherapy and 25% received blood transfusion. The highest percent parasitized erythrocytes in vaccinated cattle was 0.4% as compared with 3.6% among controls during the month of July. A significant difference (p<0.05) was observed in the rate of body weight increase. Significant difFerences were also noted in serum albumin, aspartate aminotransferase, total protein and bilirubin. Significantly more vaccinated cattle maintained normal ranges of hematological and biochemical values as compared with the control group. It is suggested that soluble merozoite T. sergenti antigens may be potential vaccine candidates for developing a genetic vaccine in Korea.

Near infrared spectroscopy (NIRS) was employed to qualify and quantify on survival, the injury rate and apoptosis of the human breast cancer cell line MCF-7 cells. MCF-7 cells were cultured in RPMI medium supplemented with 10% FCS in a 95% air and 5% CO2 atmosphere at 37$^{\circ}C$. For the viable cells preparation, cells were de-touched by 0.1% of trypsin treatment and washed with RPMI supplemented with 10% FCS medium by centrifugation at 1000 rpm for 3min. For the dead cells preparation, cells were de-touched by a cell scraper. The cells were counted by a hemacytometer, and the viability was estimated by the exclusion method with frypan blue dye. Each viable and dead cells were suspended in PBS (phosphate bufferred saline) or milk at the cell density desired. For the quantitative determination of cell death by measuring the LDH (lactate dehydrogenase) activity liberated from cells with cell membrane injuries, LDH-Cytotoxic Test Wako (Wako, Pure Pharmaceutical Co. Ltd., Japan) was used. We found that NIRS measurement of MCF-7 cells at the density range could evaluate and monitor the different characteristics of living cells and dead cells. The spectral analysis was performed in two wavelength ranges and with 1,4, 10 mm pathlength. Different spectral data pretreatment and chemometrics methods were used. We applied SIMCA classificator on spectral data of living and dead cells and obtained good accuracy when identifying each class. Bigger variation in the spectra of living cells with different concentrations was observed when compared to the same concentrations of dead cells. PLS was used to measure the number of cells in PBS. The best model for measurement of dead cells, as well as living cells, was developed when raw spectra in the 600-1098 nm region and 4 mm pathlength were used. Smoothing and second derivative spectral data pretreatment gave worst results. The analysis of PLS loading explained this result with the scatter effect found in the raw spectra and increased with the number of cells. Calibration for cell count in the 1100-2500 nm region showed to be very inaccurate.

Objectives: This study was attempted to identify the relationship between white blood cell counts and the metabolic syndrome. Methods: This study included 394 adults who visited the medical checkup center placed in Gwangju, January 1, 2008 to December 31, 2008. Index of blood test and physical checkup were performed on the study such as triglyceride, HDL-cholesterol, fasting sugar and white blood cell counts. Logistic regression analysis was used to evaluate the association between white blood cell counts, white blood cell differential count and metabolic syndrome with an adjustment age and smoking status. Results: The prevalence rate of metabolic syndrome was 25.3% among males and 13.3% among females, and was particularly high among males in their 40s. The increase in white blood cell counts lead to high prevalence of metabolic syndrome for both males and females. As white blood cell counts increased, the values of body mass index and cardiovascular risk factors were increased significantly. The odds ratio for elevated white blood cell counts increased significantly in the subjects with each components of the metabolic syndrome compared to the subjects without them. The lymphocyte counts in the white blood cell differential counts were higher in patients with metabolic syndrome than in those without. Conclusions: High level of white blood cell counts in normal range can be used as indicator in chronic inflammation. Increased white blood cell counts were significantly associated with metabolic syndrome.
Alaska pollack caught in the Northern Pacific Ocean and frozen aboard vessel are skipped to the plant and processed into frozen fillets. In the present paper quality changes during thwaing, refreezing and storage at $-20^{\circ}C$ are discussed. Natural, running-water, vacuum and steam thawing were employed as thawing methods. And contact plate, air blast, immersion in dry ice-alcohol solution freezing and storage at $-5^{\circ}C$ were applied to refreeze the thawed fillets. As quality factors content of drip released, salt-extractable protein, VBN, DNA in the drip and pH were determined. In addition, bacteriological tests were also carried out along with the whole process. In thawing of round material, the vacuum thawing was more effective than any other method, resulting in drip, salt-extractable protein $(N\%)$, VBN and DNA as $4.4\%,\;1.82\%,\;16.21mg\%$ and $13.70\;{\mu}g/ml$, respectively. Storage at $-5^{\circ}C$ as refreezing method yielded lower in drip and DNA content but similar to or slightly higher in both salt-extractable protein and VBN, which might postulate that the quality of the frozen fillet depends not largely on the secondary freezing but on the conditions of thawing and primary freezing. It seemed that most of the bacterial flora in thawed fillet came from skin and viscera of fish, worker's hands, utensils and other processing facilities, since sanitary indicative bacteria were not detected in the frozen flesh of round Alaska pollack. Bacterial quality of fillet varied with thawing methods, vacuum thawing appeared more sanitative compared with other methods as natural, running-water, and steam thawing. Bacterial colonies isolated from the thawed fillet were composed of $73.8\%$ Gram negative rod shape, $4.9\%$ Gram positive rod shape, $18.0\%$ cocci, and $3.3\%$ yeast. Decreasing rate of coliform group of the fillet during the storage at $-20^{\circ}C$ for 30 days was more than $70\%$ and that of plate count was less than of coliform group.
A general survey of 82 perschool children and 473 school children (from 1st to 3rd grade) residing in the Dongnae area of Shindong Myun, choonseoung Gun, Kangwon Province was conducted from June 12 to 21, 1973, to obtain information concerning nutritional status, especially the protein and iron nutrition of preschool and school children in a rural area of Korea. A sample of 58 children 2 to 9 years old was selected from these 555 children for hematological, biochemical and parasitological tests. The results of these tests are presented below, 1) Both the mean body height and mean body weight of these children were higher and heavier than the averages in the Korean Physical Standards. About 39 per cent were above the 90 th percentile of the Korean Physical Standards of height and 35 per cent were above the 90th percentile of the Korean Physical Standards of weight. 2) The rate of infestation by helminthes was 67.6 per cent and there were no cases of hookworm infestation Among the ascaris-infected children, 61.6 per cent fell within an Ascaris E.P.G. count range of $501{\sim}2,000$. This was considered a rather mild intensify of ascaris infection. Nutrient loss due to helminthes was also estimated to be low. 3) The mean hemoglobin level was 11.3gm% $({\pm}0.94)$, and 68.4 per cent of the children were anemic (less than 11gm% among those 5 years old or less, less than l2gm% among those 6 years old or more). The average hematocrit value was 36.1% $({\pm}2.36)$, and only 3.5 per cent showed more than 34% on the M.C.H.C. test. These results showed that the incidence of anemia, in these rural children was high, and that in general it displayed hypochromic characteristics. 4) The average serum iron level was $78.2{\mu}g%$\;({\pm}29.8). The Proportion of the children showing less than $50{\mu}g% in the serum iron level was 5.6 per cent, while 41.8 percent revealed $450{\mu}g% or more in the TIBC determination. Transferrin saturation was below 15% in 71.4 percent of the preschool children, and in 28.6 percent of the school children. Those who had a serum iron level of $50{\mu}g% or less and a TIBC of more than $450{\mu}g% constituted 11.9 percent of the children examined. From these results, it was concluded that especially preschool children were low in iron nutrition, and that most of the anemia might be iron-deficiency anemia. 5) The mean values of total serum protein and albumin were 6.98gm% and 4.99gm% respectively. Especially in serum albumin, all children stowed more than 4 gm%. 6) The mean urinary urea nitrogen Per creatinine ratio was 11.5 $({\pm}4.2)$, and 21.8 percent had a ratio of more than 15. Considering these results, it was suggested that protein nutrition in these children was relatively good.
Purpose : HUS usually occurs in children after infection with shiga toxin-producing microorganism(D+HUS). In contrast, non-postdiarrheal(D-) HUS occurs at any age and has a high rate of relapse and a poor prognosis. The clinical presentation of D-HUS is similar to that of thrombotic thrombocytopenic purpura(TTP). Recently severe deficiencies of ADAMTS13 were reported not only in TTP and D- HUS but also in D+ HUS during their acute phase. The purpose of the study is to evaluate the plasma ADAMTS13 activity in D+ and D-HUS. Methods : Nineteen children with HUS(D+ HUS 12 and D- HUS 7) were enrolled. The assays of plasma ADAMTS13 activity were performed during the acute stage in the D+ HUS and at various stages of relapsing courses in the D- HUS patients by multimer assay, based on electrophoresis. Results : The median plasma activity of ADAMTS13 in D+ HUS and D- HUS were 80.9%(37.8-132.4%) and 53.9%(1.0-94.1%), respectively, which were not statistically significantly different from control(86.4%, 34.2-112.3%)(P>0.05). One boy with D- HUS had severe deficiency of ADAMTS13(1.0%). His platelet count was normalized temporarily by fresh frozen plasma infusion. Conclusion : We have demonstrated that there is no significant difference of the plasma ADAMTS13 activity between D+ HUS, D- HUS and control. We detected severe deficiency of ADAMTS13 in one boy who presented with relapsing episodes of D- HUS. ADAMTS13 deficiency should be considered in the subgroup of D- HUS especially with early onset and recurrent courses. Plasma therapy can be beneficial in this subgroup.

Primary spinal epidural lymphoma(SEL), i.e. occurring in the absence of any detectable extraspinal lymphoproliferative disorder, is an unusual cause of spinal cord compression. The authors report a 48-year-old, diabetic woman presented with back pain followed by acute paraparesis and voiding difficulty. She had been treated with acupunctures on her back before admission, and complete blood count showed leukocytosis with neutrophilia and increased erythrocyte sedimentation rate(ESR). Thoracic spine magnetic resonance imaging(MRI) revealed an epidural mass extending from T5 to T8 with compression of the spinal cord. Emergency decompressive laminectomy was performed with a tentative diagnosis of spinal epidural abscess, but a B-cell lymphoma was final pathologic diagnosis. Further staging showed no other sites of lymphoma, and the spinal lesion was treated by chemotherapy and radiotherapy. The authors stress that primary SEL can mimic spinal epidural abscess(SEA) in the diabetic patient and should be a diagnostic consideration in patients with a syndrome of acute spinal cord compression manifested by a prodrome of back pain and neuroimaging consistent with an epidural compressive lesion, especially in a diabetic.
