Purpose: We evaluated whether it was necessary to perform whole body acquisition of $^{18}F$-FDG PET/CT including whole skull and lower extremity (LE) distal to mid-thigh (MT) in patients with multiple myeloma (MM). Materials and Methods: Thirty patients underwent 45 whole body $^{18}F$-FDG PET/CT scans including skull and LE distal to MT. PET scans were divided by 2 subgroups according to the presence of abnormal focal $^{18}F$-FDG uptake in skull or LE distal to MT. Clinical characteristics including age, sex, and stages were compared between the 2 subgroups. Results: Of total 45 whole body PET/CT scans, focally increased abnormal FDG uptake in the skull or LE distal to MT suggesting myeloma involvement was found in 22 scans (48.9%) of 14 patients (46.7%). Skull lesions were more frequently observed than LE lesions distal to MT on PET (86.4% vs. 40.9%, p<0.005). There were no significant differences in age, sex, initial Durie/Salmon stage, and tumor burden at the time of PET scan suggested by serum hemoglobin level, serum calcium level, serum and urine paraprotein level, and serum creatinine level between the two subgroups. The presence of the skull or LE distal MT lesions on PET did not affect on the Durie/Salmon plus stage except only 1 case (1/22, 4.5%, p>0.05). Conclusion: Abnormal lesions in the skull or LE distal to MT on $^{18}F$-FDG PET/CT did not affect significantly on the tumor burden and Durie/Salmon plus stage of MM. Therefore, torso PET acquisition including head may be sufficient for evaluating patients with MM.

운동여부와 운동횟수 그리고 어체 크기에 대한 양식산 어종의 품질판정을 위한 지표를 검색하기 위하여 효소적 방법 즉 ATP 관련화합물과 양식산 활어의 건강한 상태와 칼슘의 노출, 염도의 감소, 산소의 부족, 궁핍 등과 같은 스트레스를 받은 상태를 판단하는 adenylate energy charge (AEC)를 근육의 품질판정을 위한 지표로써 조사하였다. 운동사육구와 비운동사육구에서의 참돔육에 대한 ATP 관련화합물의 변화는 운동 0일에는 ATP함량은 8.62 μmol/g이었지만 20일차에는 8.59 μmol/g으로 운동기간이 길어짐에 따라 ATP의 함량은 약간의 감소를 보였다. 이는 운동이라는 자극요인으로 인하여 ATP의 소모가 촉진되었을 것으로 판단된다. 또한 운동 0일차의 ADP함량은 0.72 μmo1/g이었지만 20일차에는 0.93μmol/g로 ATP의 소모만큼 약간의 증가를 보이고 있다. 반면, 비운동사육구에서 0일차의 ATP함량은 5.78 μmol/g이었지만 20일차에서는 6.31 μmol/g로 운동사육구와 대조적으로 기간이 길어짐에 따라 ATP함량이 약간의 증가를 보여주고 있다. 생리적으로 동물에 가혹한 환경에 두거나 스트레스를 가하면 adenylate energy charge (AEC)가 영향을 받아 변화게 된다. AEC는 (ATP ＋ ½ ADP)/(ATP ＋ ADP + AMP)의 비율로 정의되는데, AEC의 범위는 0∼1사이로써 0은 ATP 관련화합물이 AMP로 전환된 상태를 말하며, 1은 모든 ATP 관련 화합물이 ATP로 존재하는 것을 의미한다. 그러므로, 이들결합의 상관적인 정도는 개개의 세포에서 에너지의 효용성을 측정하는 것으로 이용되고 있다. AEC 수치는 운동수조에서 0.91∼0.92 건강상태가 좋았지만 비운동수조는 0.87∼0.88로 운동수조에 비해 값이 낮게 나왔다. 운동횟수에 관계없이 운동시킨 어육의 AEC는 0.90∼0.91로 건강한 상태였다. 어체크기에 따른 ATP 관련화합물의 변화는 0.7∼0.9kg의 크기를 가진 참돔에서는 ATP 함량이 7.88 μmole/g, 1.5∼l,7kg의 크기를 가진 참돔에서는 ATP함량이 9.61μmole/g로 많았고 다른 크기에서는 큰 차이를 나타내지 않았다. 그리고 ADP함량은 어체의 크기가 증가할수록 함량은 감소하였다. 그러나, 어체의 크기에 따른 ATP관련화합물의 변화는 거의 없었다. 건강도의 지표인 AEC는 0.89∼0.94로 전체적으로 건강상태로 나타났다. 하루 2회 운동시킨 육에서의 ATP함량은 0일차에 8.75 μmole/g, 10일차에 8.46 μmole/g, 20일차에 8.51μmole/g로 약간의 감소를 보여준다. ADP함량은 일까지는 증가하지만 그 이후에는 큰 변화를 보이지 않는다. 6시간 운동시킨 그룹의 ATP함량은 0일차에 8.63 μmole/g, 5일차에 8.52 μmole/g, 10일차에 8.4μmole/g, 20일차에 8.51 μmole/g로 10일까지는 감소하지만 그 이후에는 큰 변화를 보이지 않는다. ADP함량은 0일차에 0.72 μmole/g, 10일차 0.84 μmole/g, 20일차에 0.83 μmole/g으로 10일차까지는 약간 증가하지만 그 이후에는 큰 변화를 보이지 않았다. 참돔의 근원섬유에 있어서 Ca/sup 2+/이 존재할 때 Mg/sup 2+/-ATPase 활성의 변화는 운동시킨 참돔 근원섬유의 Mg/sup 2+/-ATPase 활성은 0.35μmol Pi/minㆍmg였으며, 비운동구에서 0.34μmol Pi/minㆍmg으로 운동시킨 참돔의 육에서 ATPase 활성이 약간 높은 것으로 나타났다. 운동사육시킨 참돔은 운동기간이 증가할수록 ATPase활성이 증가하여 운동 20일에는 0.42μmo1 Pi/minㆍmg의 함량을 나타내었으나, 비운동사육에서는 큰 차이를 보이지 않고 있다. 근원섬유의 Ca/sup 2+/가 첨가되지 않았을때의 Mg/sup 2+/-ATPase 활성을 나타내었다. 운동시키전에는 각각 0.10μmol Pi/minㆍmg, 0.14μmol Pi/minㆍmg 나타나 비운동구가 운동구에 비하여 Mg/sup 2+/(-Ca/sup 2+/)-ATPase 활성이 높았으며 사육기간동안 활성이 서서히 감소하는 경향을 나타내었다. Ca/sup 2+/-ATPase의 활성 또한 사육기간 동안 큰 변화를 보이지 않았다. 그러므로, 참돔의 운동여부에 따라서 ATPase활성을 살펴본 결과, 운동기간에 따른 약간의 차이는 보이고 있으나, 품질지표로써 사용하기가 어렵다고 판단된다. 효소적인 방법을 이용한 양식산 활어의 품질지표로써 ATP 관련화합물, ATPase 활성은 운동여부, 크기에 따라 객관적인 지표로써의 사용이 어려우므로, 건강도를 측정할 수 있는 AEC의 수치를 적용하는 것이 적합하다고 판단된다. 즉, 양식산 참돔의 AEC 수치가 1∼0.9의 범위에서는 건강한 활어로 상급의 등급을, 0.8∼0.7의 AEC 수치는 중급의 등급으로, 그 이하의 수치에서는 하급으로 적용가능 하다고 판단된다.

Infantile osteopetrosis is a rare congenital disorder caused by abnormal bone resorption. Patients with osteopetrosis can have severe anemia, thrombocytopenia, hepatosplenomegaly, rickets, visual impairment, and deafness. Cytomegalovirus also can cause a congenital infection with anemia, thrombocytopenia, hepatosplenomegaly, and calcifications in the brain. We report a 38-day-old infant with severe hepatosplenomegaly, thrombocytopenia, hypocalcemia, and growth failure. Real time polymerase chain reaction detected cytomegalovirus in the plasma. Skeletal radiography revealed generalized bone sclerosis. He was diagnosed with osteopetrosis along with cytomegalovirus infection. Only the test for mutation of the CLCN7 gene, representing the most common and heterogeneous form of osteopetrosis, was available, and the result was negative. With supportive care and antiviral treatment, severe thrombocytopenia due to the cytomegalovirus infection almost normalized despite the possible immunosuppression caused by osteopetrosis. We present the first report of an infant who suffered from osteopetrosis and CMV infection which was successfully treated by long term antiviral agent therapy.

Normal range has use mainly in the first phase of the diagnostic process, that is, to screen or to raise ideas about possible pathology. The traditional method of determining it is based on the probability paper or on the mean plus or minus two standard deviations. These methods are often turned out to be vague and impractical. The percentile method is adequate and flexible, though. The appropriate limit of lower and upper points should be chosen by considering medical aspects above all things and also the reliability of the range determined by the standard error. The results of normal range are interesting, strictly speaking, only for the hospital concerned. Differences exist between the normal ranges reported by various sources (Bezemer et al, 1983). It would be best to establish the normal range based on a population comparable to a group of individuals to whom the normal range is to serve as a norm.

This study was established to investigate the effects of Ca application on fruit mineral nutrients, quality, and browning of 'Fuyu' sweet persimmon (Diospyros kaki). Ca foliar application at 40ml/20L/tree had a greater fruit Ca concentration than did control, Ca fertigation (40ml/20L/tree), and Ca foliar application (40ml/20L/tree) coupled with IBA fertigation (40ml/20L/tree). Fruit mineral nutrient concentrations for Mg, B, and Mn were similar or lower in the foliar treatment compared to other treatments. Fruit color was not affected. Ca treatment, whether foliar applied or fertigated, was effective in maintaining fruit firmness and in decreasing the browning symptom in fruit after MA storage at $0^{\circ}C$ for 60 and 100 days. Although Ca foliar application + IBA fertigation treatment improved fruit firmness, the positive effect on the browning and decay occurrences in fruit was not shown.

The aim of this study was to investigate the association dining-out frequency, nutritional intake level and health risk factors related to metabolic syndrome among Korean women. The data in this study were obtained from the Korean National Health and Nutrition Examination Survey in 2013 (KNHANES VI). Sample of Korean women (n=3,413), aged over 20 with biochemical, dietary and health screening data, was divided into three groups according to dining-out frequency; "Rarely" (< 1 time / week), "Occasionally" (2~4 times / week) and "Frequently" (${\geq}5times/week$). The results showed that there were significantly different intake levels in energy, water, protein, fat, calcium, sodium and vitamin A according to the dining-out frequency. Each dining-out frequency group was significantly associated to obesity and Low HDL Cholesterolemia. In conclusion, this study found significant association between dining-out frequency, nutritional intake and health risk factors among Korean women. Further studies are necessary to examine subdividing into age and dining-out frequency and health risk factors related to metabolic syndrome among Korean.

Twelve Punchong sherds collected in Hakbongni, Kongju where the well known iron-painted on white slip were manufactured from late 15C to early 16C were analyzed for their composition and microstructure. The composition of the body was analyzed by X-ray fluorescence and that of glaze by electron probe micro-analyzer. Microstructure was observed by optical microscope, polarizing microscope, EPMA, and X-ray diffractometer. The results of composition of body and glaze of Hakbongni were compared with those of Punchong from Yongsuri, Boryong which was close to Hakbongni. The composition of body and glaze of these two areas were compared by principal component analysis using SPSS program. Hakbongni bodies have higher silica and flux materials but lower alumina and their glaze have higher silica, soda, iron oxide but lower alumina, calcia. Hakbongni punchong itself is divided into two groups. Their glaze is lime type. There are many remnant minerals, such as quartz, large feldspar mass with partially melted surrounding area, albite, biotite, and iron-oxide. From such a microstructure we can assume that preparation of raw material was rather crude and firing temperature quite low. Iron-painted material is identified as Mg/Fe/Al spinel by composition analysis and XRD pattern.

Di-2-ethylhexyl phthalate (DEHP) is a widely used plasticizer known to be a suspected xenoestrogen and a causative agent of oxidative damage to the RBC cell membrane ir vitro. We evaluated the toxic effects of a scarcely documented aquatic environmental pollutant, DEHP, on selected haematological endpoints in the bagrid catfish, Pseudobagrus fulvidraco. Bagrid catfish were exposed to DEHP (300, 1,000 mg DEHP kg body weight$^{-1}$) through thrice intraperitoneal injection and effects were assessed in blood of the exposed organisms. Haematological property, serum organic and inorganic chemistry were monitored in blood of Bagrid catfish. DEHP exposed-fish showed erythropenia; low hematocrit (Ht) and hemoglobin (Hb) content and red blood cell count showed a significantly higher than in that of the control group. The treatment group showed a significantly lower concentration of serum total protein, cholesterol and triglyceride compared with those in the control group. The value of calcium and osmolality were significantly decreased in the DEHP treatment group, compared with the control group.

This experiment was earned out with $^32$P labeled phosphate and lime to determine the optimum amount of phosphate and lime fertilizers to soybean under various types of soil. The determination was made by the index of absorption of phosphate by soybean plants. The index of phosphate was 854 (mg/100g) in non matured soil. Due to the capability of neutralization of calcium the PH of the soil was raised to 6.5. The highest yield was obtained in matured soil at the index of phosphate absorption at 5% level. The degree of contribution of phosphate in. non matured soil showed slightly higher tendancy than that in matured soil.

Purpose: The aim of this study was to explore the relationship of ready-to-eat cereal (RTEC) consumption with nutrition and health status. Examination of health status for this project included obesity, abdominal obesity, hypertension, hypertriglyceridemia, hypercholesterolemia, low-HDL-cholesterolemia, diabetes, anemia, and metabolic syndrome. Methods: Two groups, RTEC consumers and those who did not consume RTEC, were identified using 24-hour dietary recall data from the 2012 Korea National Health and Nutrition Examination Survey (KNHANES). Nutritional intakes and risk factors of the two groups were compared using covariates-adjusted statistical procedures. Statistical analyses were performed using SAS survey procedures, and strata, cluster, and weight were considered. Subjects of analysis of nutritional intake were between the ages of 1 and 75, and those considered in the risk factor analysis were between the ages of 19 and 75. Results: Results showed that 3.8% of the Korean population was RTEC consumers. Compared to the subjects who did not intake RTEC, RTEC consumers exhibited significantly higher intakes of calcium, thiamin, riboflavin, and vitamin C. It was also discovered that the percentage of people whose intakes were less than EAR decreased with RTEC consumption. RTEC consumption showed significant association with decreased systolic blood pressure, diastolic blood pressure, serum triglyceride, and serum total cholesterol. Consequently, prevalence of hypertension among RTEC consumers was significantly lower than that among non-consumers, and the odds ratio for hypertension was 0.19 after adjusting the models for covariates. Conclusion: Results of this study clearly suggest an association of RTEC consumption with improved nutritional status and cardiometabolic risk profile in Korean adults. Conduct of additional studies will be necessary in order to determine the nature of these relationships.
