After the first description of IgA nephropathy by Berger in 1968, the prognosis of this disease was considered favourable. However recent studies have revealed that IgA nephropathy result in end stage renal desease in 25-30% by 20 years. Heavy proteinuria, hypertension, histological high class are regarded as poor prognostic factors. In 1996, Yagame et al reported the new histopathologic grading with a strong correlation between the grading, heavy proteinuria, high s-Cr level and renal survival. The aims of this study are to determine whether the pathological grading and other clinical parameters could contribute to predicting the outcome of this disease eventhough pediatric patients. Seventy nine patients (59 males, 20 females) with IgA nephropathy were examined. Patients were 2.08-15.17 years of age ($9.85{\pm}2.83$). The mean follow-up duration were $27{\pm}28$ months. Six of seventy nine patients progressed to chronic renal failure during the follow-up periods. High 24h urinary protein excretion at diagnosis were significantly higher in chronic renal failure patients (p<0.05). Hypertension at diagnosis were the significant associated factors in progression of chronic renal failure (p<0.05). Histological changes of IgA nephropathy in light microscopy were classified into five classes by WHO classification, four grades in Yagame's gradings. Among the seventy nine patients, 24 were as class 1, 30 as class 2, 23 as class 3; 4 as class 4, 0 as class 5 by WHO classification. 23 were classified grade 1, 31 as grade 2, 24 as grade 3, 1 as grade 4 by Yagame's grading. Among six patients who progressed to chronic renal failure, 1 clssified as class 1, 1 as class 2, 3 as class 3, 1 as class 4, 0 as class 5 by WHO Classification. 1 patients were classified as grade 1, 1 as grade 2, 3 as grade 3, 1 as grade 4 by Yagame's grading. (p>0.05) In conclusion, hypertension and heavy proteinuria at initial presentation were significantly associated with progression of chronic renal failure. The classification of WHO & Yagame's grading has no significant association with the progression of chronic renal failure in pediatric patients.

Purpose : We intended to decrease late CNS reaction after radical radiotherapy for an intracranial germinoma by using combined neoadjuvant chemotherapy and involved-field radiotherapy. The efficacy in terms of its acute toxicity and short-term relapse patterns was analyzed. Materials and Methods : Eighteen patients were treated with combined neoadjuvant chemotherapy and radiotherapy between 1995 and 2001. The chemotherapy regimen used was the Children's Cancer Group (CCG) 9921A (cisplatin, cyclophosphamide, VP-16, vincristine) for 5 patients younger than 16 years, BEP (bleomycin, VP-16, cisplatin) for 12 patients, and EP (VP-16, cisplatin) for 1 patient. The radiotherapy covered the whole craniospinal axis for 5 patients, the whole brain for 1, and the partial brain (involved field) for 12. the primary lesion received tumour doses between 3,960 and 5,400 cGy. Results : The male to female ratio was 16:2 and the median age was 16 years old. The tumors were located in the pineal gland in 12 patients, in the suprasellar region in 1, in the basal ganglia In 1, in the thalamus in 1. Three patients had multiple lesions and ventricular seedings were shown at MRI. In 3 patients, tumor cells were detected in the cerebrospinal fluid and MRI detected a spinal seeding in 2 patients. The response to neoadjuvant chemotherapy was complete remission in 5 patients, partial remission in 12, and no response in 1. However, after radiotherapy, all except 1 patient experienced complete remission. The toxicity during or after chemotherapy greater than or equal to grade III was remarkable; hematologic toxicity was observed in 11 patients, liver toxicity in none, kidney toxicity in none, and gastrointestinal toxicity in one. One patient suffered from bleomycin-induced pneumonitis. Radiotherapy was therefore stopped and the patient eventually died of respiratory failure. The other 17 are alive without any evidence of disease or relapse during an average of 20 months follow-up. Conclusion : A high response rate and disease control was experienced, which was the same as observed other studies and the morbidity from chemotherapy-induced toxicity was similar. With these results, the results from adjuvant chemotherapy and involved-field radiotherapy cannot be concluded to be equal to those from extended-field radiotherapy. The long term follow-up study on later complications are required in order to draw definite conclusions on the optimal management with minimum side effects.

Purpose : Effects to predict tile progression of chronic renal failure (CRF) in children, using mathematical models based on transformations of serum creatinine (Scr) concentration, have failed. Error may be introduced by age-related variations in creatinine production rate. Height (Ht) is a reliable reference for creatinine production in children. Thus, Scr, factored for Ht, could provide a more accurate predictive model. We examined this hypothesis. Methods : The progression of of was detected in 63 children who proceeded to end-stage renal disease. Derivatives of Scr, including 1/Scr, log Scr & Ht/Scr, were defined fir the period Scr was between 2 and 5 mg/dl. Regression equation were used to predict the time, in months, to Scr > 10 mg/dl. The prediction error (PE) was defined as the predicted time minus actual time for each Scr transformation. Result : The PE for Ht/Scr was lower than the PE for either 1/Scr or log Scr (median: -0.01, -2.0 & +10.6 mos respectively; P<0.0001). For children with congenital renal diseases, the PE for Ht/Scr was also lower than for the other two transformations (median: -1.2, -3.2 & +8.2 mos respectively; P<0.0001). However, the PEs for children with glomerular diseases was not as clearly different (median: +0.9, +0.5 & +9.9 respectively). In children < 13 yrs, PE for Ht/Scr was tile lowest, while in older children, 1/Scr provided the lowest PE but not significantly different from that for Ht/Scr. The logarithmic transformation tended to predict a slower progression of CRF than actually occurred. Conclusion : Scr, floored for Ht, appears to be a useful model to predict the rate of progression of CRF, particularly in the prepubertal child with congenital renal disease.

Purpose : Several studies have reported the recent increase in the incidence of acute poststreptococcal glomerulonephritis(APSGN). The objective of this study is to see changes of clinical findings/manifwstation in children with APSGN. Methods : Medical records of 63 children who were diagnosed with APSGN in the deparment of Pediatrics, Kyungpook National University Hospital, between January 1992 and December 2006 were reviewed retrospectively. We analyzed various clinical characteristics such as age, sex, degrees of proteinuria, degrees of hematuria, and presence or absence of histories of systemic antibiotic use in children with APSGN, and compared the children with APSGN who were diagnosed between 1992 and 2000 to those who were diagnosed between 2001 and 2006. Results : Age of the patients ranged from 2-14 years(median 7.11 years) at the time of disease onset. Study patients consisted of 41 boys and 22 girls. APSGN followed infection of the throat in 87% of cases. Patient developed an acute nephritic syndrome 12 days after an antecedent streptococcal pharyngitis. Forty patients presented with gross hematuria. Fortyone patients had hypertension at the time of diagnosis. Hypertension disappeared within 7.8$\pm$8.2 days, gross hematuria within 11.3$\pm$17.2 days and microscopic hematuria within 3.5$\pm$3.9 months from the disease onset. Patients in 2001-2006 had significantly higher increase of antistreptolysin O(ASO) titer. However, no significant differences in clinical characteristics were observed. Age, sex, severity of proteinuria, gross or microscopic hematuria, antibiotic therapy did not affect the clinical manifestations of glomerulonephritis. In other words, hypertension, duration of hematuria, recovery of serum C3 level are not different between the two time periods. Conclusion : Our data indicates that patients in 2001-2006 had significantly higher level of ASO titer. However, they did not show significant clinical differences. To evaluate the causes of the resurgence of APSGN, a national epidemic is needed.

Young black men(YBM) have the most severs levels of high blood pressure(HBP) and, in all reports but one, the lowest of HBP control of any age /sex /race group. To increase entry into care, remaining in care, and BP control for young(18-49 years) Black men, It is needed to review socio-demographic, medical characteristics, and behaviors(importance of and difficulty with HBP control behaviors, or worry about mdication) for experimental intervention study(educational- behavior strategies) of hypertensive urban young black men. The 204 participants had an average age of 38.8+7.0 years and an average educational level of $11.0{\pm}2.4$ years; only 23.1% were employed full- or part-time while 26% were on disability ; and 6% were married. Only 35.3% had an MD for HBP care and 37.3% had some form of health insurance. The average BP of those men currently being in care on medication(35.3%) was $148.2/95.1{\pm}19.5/11.3$ compared to those men not taking HBP care $153.7/99.1{\pm}14.0/9.8(p<.05)$. The average creatinine level was 1.3(excluding 3 marked elevations of 15.9, 9.6, and 7.7) for the 163 men consenting to have their blood drawn. Self-reported co-morbidity induded heart disease 7.8%, diabetes 8.9%, high cholesterol 18.2%, CVA 3.4%, alcohol and drug related problems 27.9% and 22.5% respectively. The kidney disease of those men currently being in care & on medication was 9.7 compared to those men not taking HBP care 0.8(p<.05). The problems of with sex life, physicl activity and dearly thinking of those men currently being in care & on medication was higher compared to those men not taking HBP care(p<.05). Questions of 'during the past month, on how many days did you have 5 or more drinks (bottles) of any alcoholic beverag?' and smoking of those men currently being in care & on medication was 18.1% and 72.2% compared to those men not taking HBP care 27.3 and 82.6%, respectively. HBP control behaviors was assessed with 1-5 point Likert subscales(5=extreme, 1-none at all), In general, th men reportd low levels of perceived psychological barrier to HBP care and control behaviors; importance of and difficulty with HBP control behaviors, or worry about mdication. For example, on a five point scale(1=none at all, 5=extreme), average ratings for perceived important and difficulty with BP care and behaviors were 2.8(SD=1.2) and 2.5(SD=1.1). Average ratings for perceived benefit with BP care and behaviors worry about medication of those men currently being in care on medication was 4.0(SD=0.9) and 2.2(SD=1.1) compared to those men not taking HBP care 3.6(SD=0.8), 2.8 (SD=1.6) respectively(p<.05). These data support the need for educational-behavioral strategies of community health nurse to improve high blood pressure control in this high risk group through perceived barriers to treatment, health care skills and use of resources, and social support.

Purpose : This study was peformed to study normative blood pressure data in full-term neonates that may be used to facilitate Identification of neonatal hypertension.Methods : 383 newborns born in our hospital from May 2003 to January 2004 were enrolled in this study Using an oscillometric device(BP-88 NEXT, COLIN Corp.), their blood pressures were measured more than one time within a week after birth. According to each clinical variable such as sex, delivery mode, birth weight, gestational age and presence of maternal disease or perinatal problems, we divided the population into groups and calculated the mean blood pressures of each group. We compared mean blood pressures between the divided groups according to each clinical variable statistically.Results : Mean systolic and diastolic blood pressure of the Population was 70.8$\pm$ 10.9 mmHg and 43.4 $\pm$ 8.0 mmHg, respectively. There was no satistically significant difference in blood pressure according to clinical variables. Mean systolic pressure showed positive correlation with birth weight and gestational age(r=0.1420, 0.03130).Conclusion : Our results are almost in agreement with Zubrow's data from 695 newborns in U.S.A, 1995. Our data may be helpful for early detection and management of neonatal hypertension, thereby maintaining renal function ,and preventing possible complications of renal disease.

Purpose: In children, 24-hour urine collections are unreliable for evaluating glomerular filtration rate (GFR) because of the difficulty of regulating voiding and the daily variation of urinary creatinine up to 25%. Additionally, creatinine clearance (Ccr) based on urinary creatinine is considered inaccurate. The purpose of this study was to compare estimated GFR determined using Ccr, formulas with serum cystatin C and creatinine, and $^{99m}Tc$-mercaptoacetyltriglycine (MAG3) dynamic renal scintigraphy. Methods: This retrospective study included 101 patients (age, <18 years) who visited Chung-Ang University Hospital between July 2011 and August 2012. GFR was estimated using 24-hour urinary creatinine, five formulas with serum creatinine and cystatin C, and $^{99m}Tc$-MAG3 renal scan. Results: Of the 101 patients, glomerular renal diseases were present in 60 patients (59.4%) and non-glomerular diseases were present in 41 patients (40.6%). There was a significant correlation between estimated GFR determined using $^{99m}Tc$-MAG3 renal scan and Ccr (r=0.389, P <0.001). The correlation values between estimated GFR determined using $^{99m}Tc$-MAG3 renal scan and each formula of Schwartz, Counahan-Barratt, Cockcroft-Gault, Filler and Lepage, and Bokencamp were 0.265 (P=0.007), 0.128 (P=0.044), 0.230 (P=0.021), 0.356 (P<0.001), and 0.355 (P <0.001), respectively. $^{99m}Tc$-MAG3 renal scan was correlated with estimated-GFR by all formulas in decreased renal function. Conclusion: Estimated GFRs determined using serum creatinine and cystatin C, and $^{99m}Tc$-MAG3 renal scan correlated well with estimated GFR determined using Ccr. $^{99m}Tc$-MAG3 renal scan may be replaced for evaluation of renal function with convenience in patients with renal disease and decreased renal function in childhood.

This study was aimed to investigate the effects in different immersion doses of garlic, Allium sativum, juice to modulate on the nonspecific immune responses of the olive flounder, Paralichthys olivaceus, artificially prechallenged with Streptococcus iniae BS10 and Edwardsiella tarda KE-1, respectively. The nonspecific immune responses of the tested fish were assessed in term of skin mucus lysozyme activity, the change of bacterial cell counts in organs, the number of lymphocytes and neutrophils in blood, and SOD activity. Almost groups of the prechallenged with either S. iniae BS10 or E. tarda KE-1 fish which had been immersed in garlic juice showed the enhanced skin mucus lysozyme activity, the number of lymphocytes and neutrophils in blood, and SOD activity in the kidney but the decreased the number of bacterial cell in surveyed organs. RPS in the group immersed in 0.25 g/L of garlic juice was much higher than in other immersed test groups. These results suggested that the garlic juice immersion can be effective on enhancement of the nonspecific immune responses and the protective ability of olive flounder to the artificial challenge with S. iniae BS10 and E. tarda KE-1.

The innate immune response is fundamental defense response of vertebrates and invertebrates. Especially, the innate immune response important for larvae that lack of resistance to infectious diseases in the early stages. Galectin is one of the kinds of lectin and presents in the fish mucous that involves innate immune response. Galectin have been studied from various fishing species, but expression analysis of galectin is still unclear during early developmental stage in olive flounder. In this study, we investigated gene expression of galectin-1 from various developmental stage and tissues. We excised several tissues including the muscle, fin, eye, gill, brain, stomach, intestine, kidney, spleen and liver from adult olive flounder and confirmed gene expression of galectin-1 using RT-PCR and quantitative real-time PCR. Expression of galectin-1 was significantly higher in muscle, stomach and intestinal tissue than other tissue in adult fish (5 and 29 months). Also, galectin-1 gene was detected from 0 DAH and gradually increased to 35 DAH and since then decreased after stomach development period. Induction of galectin-1 during the early developmental stage suggest that muscle, fin and eye tissue is formed and begins the secretion of galectin this period. In addition, increased expression levels at 35 DAH suggest that due to complete formation of stomach and intestine, increase of secretion and activation of enzyme. This study shows that expression of galectin-1 during early developmental stages and adult period in olive flounder and can be expect that galectin-1 play essental role in the innate immune system throughout the whole life time. Galectin-1 is primary barrier such as skin and digestive tissue against pathogen infection, also digestive tract developmental period is important for pathogen invasion can be expected that it will serve. Mass mortality due to the disease in seed production is continuing damage, therefore these result will be meaningful about infectious disease during early developmental stages as a basic data for the study.

Among the employer-supported subscribers to the National Health Insurance Service, 6,797 people with mild disabilities with western ages of 20 and up and who received health checkups were investigated. Of these 6,797 people, 3,186 and 3,611 received health checkups in 2009 and 2013, respectively. Those people who were diagnosed with physical handicaps, brain lesions, visual impairment, hearing impairment, intellectual disabilities, mental disorders, kidney disorders or other disorders according to the classification standard for people with disabilities were classified into disability groups of the 3rd through 6th degrees. The purpose of this study was to examine the dangerous influence of obesity of people with mild disabilities on their hyperglycemia, hypertension and high cholesterol. The items measured in this study were abdominal obesity, body mass index, fasting glucose, total cholesterol, systolic blood pressure and diastolic blood pressure. To look for connections between the obesity level and at-risk groups for each disease, cross tabulation and multinomial logistic regression analyses were utilized. Higher levels of abdominal obesity and BMI were found among those who were male, were younger and had higher incomes. The risks of abdominal obesity and BMI were higher in the abnormal groups for each disease. In 2009, the obesity group whose BMI was higher had a 1.51-fold higher risk of hypertension than the normal group. The abdominal obesity group had a 1.59-fold higher risk of high cholesterol, a 1.26-fold higher risk of hypertension and a 1.54-fold higher risk of hyperglycemia than the normal group. In 2013, the obesity group whose BMI was higher had a 1.72-fold higher risk of high cholesterol and a 1.43-fold higher risk of hypertension than the normal group. Those with abdominal obesity had a 1.59-fold higher risk of hyperglycemia than the normal subjects. As the risk of obesity was higher in those with disabilities than in those without disabilities, the former should be encouraged to undergo health checkups on a regular basis, and the coverage of the health checkups should be extended to keep track of their illness. In addition, appropriate education and concern are both required to prevent obesity.
