The purpose of this study was to analyze women's health problems using Green & Kreuter's(1991) PRECEDE model and to develop health education program for women's health. The subjects were recruited women from Wonju city 18 years or older. 1. The results showed that about 50% of the women were satisfied with their lives as women, 23% of the sample felt there was a need for a women's health care center. The mean number of health problems was 3.1 and the prevalence rate, 44.4%. 2. We developed on educational program according to group differences related to health problems, diagnosis of disease, variables influencing health promotion behavior, and programs which each group wanted. Also we stressed self-efficacy and self-help group for the management of individual health to all groups. 3. The diagnoses of diseases that were experienced premarital over the past year were gastritis, bronchitis, spinal disk, and fracture, for the childbearing/rearing group, gastritis, vaginitis and cervicitis, cervical cancer and cystitis and nephritis and arthritis and for the middle-aged/elderly group arthritis, gastritis, vaginitis and cervicitis, and spinal disk. Of the sample 30.5% did not have a health exam in the past year, and only 10% of the premarital group, 12.5% of the childbearing/child-rearing group, and 18.3% of the middle aged-elderly group were concerned about their health and did something for their health. 4. The average score on the HPLP was 2.41. the HPLP was scores according to group were found to have significant differences. self-efficacy, family functions, health attention and were considered important variables in the premarital group, in the childbearing/child-rearing group self-efficacy, family functions, internal locus of control, health attention, and health perception and power others locus of control and then for the middle aged-elderly group self-efficacy, health attention, internal locus of control, family functions and health perception. 5. There are a few educational programs in the city provided by the Wonju Health Center and by community health nurse practitioners. The premarital group requested the educational programs on diet, health exercise, family health and stress management. Also the childbearing/child-rearing group wanted programs on diet, family health, stress management, and health exercise, and the middle-aged/elderly group wanted that of family health, diet, climacteric changes stress management and health exercise. The program suggested that this program should be applied to women in the community to insure adequate management of women's health. Follow-up research with PROCEED is needed to analyze health outcomes, also, a women's health nursing specialist system is required to develop health promotion, and improve the quality of life for women.

Background and Objectives The representative mucin genes in the human airway are MUC5AC and MUC5B, which are regulated by several inflammatory and anti-inflammatory substances. Triptolide (TPL), udenafil, betulinic acid, changkil saponin, and glucosteroid are some of the many anti-inflammatory substances that exist. TPL is a diterpenoid compound from the thunder god vine, which is used in traditional Chinese medicine for treatment of immune inflammatory diseases, such as rheumatoid arthritis, systemic lupus erythematosus, nephritis and asthma. However, the effects of TPL on mucin expression of human airway epithelial cells have yet to be reported. Hence, this study investigated the effect of TPL on lipopolysaccharide (LPS)-induced MUC5AC and MUC5B expression in human airway epithelial cells. Subjects and Method The NCI-H292 cells and the primary cultures of human nasal epithelial cells were used to investigate the effects of TPL on LPS-induced MUC5AC and MUC5B expression using real-time polymerase chain reaction, enzyme immunoassay, and Western blot. Results TPL significantly decreased the LPS-induced MUC5AC and MUC5B mRNA expression and protein production. TPL also significantly decreased the nuclear factor-kappa B (NF-kB) phosphorylation. Conclusion These results suggest that TPL down regulates MUC5AC and MUC5B expression via inhibition of NF-kB activation in human airway epithelial cells. This study may provide important information about the biological role of triptolide on mucus-secretion in airway inflammatory diseases and the development of novel therapeutic agents for controlling such diseases.

Purpose: The long-term efficacy and safety of infliximab (IFX) in children with ulcerative colitis (UC) have not been well-evaluated. Here, we reviewed the long-term durability and safety of IFX in our single center pediatric cohort with UC. Methods: This retrospective study included 20 children with UC who were administered IFX. Results: For induction, 5 mg/kg IFX was administered at weeks 0, 2, and 6, followed by every 8 weeks for maintenance. The dose and interval of IFX were adjusted depending on clinical decisions. Corticosteroid (CS)-free remission without dose escalation (DE) occurred in 30% and 25% of patients at weeks 30 and 54, respectively. Patients who achieved CS-free remission without DE at week 30 sustained long-term IFX treatment without colectomy. However, one-third of the patients discontinued IFX treatment because of a primary nonresponse, and one-third experienced secondary loss of response (sLOR). IFX durability was higher in patients administered IFX plus azathioprine for >6 months. Four of five patients with very early onset UC had a primary nonresponse. Infusion reactions (IRs) occurred in 10 patients, resulting in discontinuation of IFX in four of these patients. No severe opportunistic infections occurred, except in one patient who developed acute focal bacterial nephritis. Three patients developed psoriasis-like lesions. Conclusion: IFX is relatively safe and effective for children with UC. Clinical remission at week 30 was associated with long-term durability of colectomy-free IFX treatment. However, approximately two-thirds of the patients were unable to continue IFX therapy because of primary nonresponse, sLOR, IRs, and other side effects.

Purpose : The cause and pathogenesis of Henoch-Sch$\ddot{o}$nlein purpura (HSP) are unknown, but recently the hypothesis that immunoglobulin A may have an important role in the pathogenesis of HSP is being published and HSP associated with mycoplasma infection has been also reported. The aim of this study is to discover relation between HSP and mycoplsma infection. Methods : From Jan. 2002 to Dec. 2005, we retrospectively evaluated 98 children who were diagnosed as HSP at Ilsan Paik Hospital. 84 patients were not associated with mycoplasma infection (group A) and 14 patients were associated with mycoplasma infection (group B). We compared both groups about clinical features. Results : The ratio of male to female patients in group A and B were 1.21:1 and 1.80:1. The number of patients in group A was most in November and December, and in group B was most in November. All patients had non-thrombocytopenic purpura concentrated on the buttocks and lower extremities and joint involvement was most common on the feet and ankle in both groups. 57 (67.9%) cases in group A and 9 (64.3%) cases in group B complained of abdominal pain. And 21 (25.0%) cases in group A and 5 (35.7%) cases in group B had nephritis. Elevated mycoplasma antibody titer (${\geq}1:320$) or 4 fold-rise were noted in 14 of 98 patients (14.3%). In this study, there was one child with HSP preceded by typical mycoplasma pneumonia (mycoplasma antibody titer 1:1280). Conclusion : In this study, elevated mycoplasma antibody titer (${\geq}1:320$) or 4 fold-rise were noted in 14 of 98 patients and the difference of clinical features between group A and B was not specific. The role of mycoplasma infection in the etiology of HSP may have been implicated, so the association with mycoplasma infection should have to be proved by further controlled studies.

This retrospective study was designed to evaluate the prognostic value and histologic correlation of sonography in childhood nephrotic syndrome. Sixty-nine patients with proteinuria over 2g per day at the time of presentation who were treated at the Korea University Hospital were included in this review. They were 1 to 15 years old(mean age, 7.8 years) with 49 males and 20 females. In each patient an ultrasound examination was done using SPA 1000(Diasonics, C.A., U.S.A.) on admission. Tissue specimens were obtained from 46 patients. The paraffin-embedded specimens were reviewed with special reference to interstitial edema, interstitial fibrosis, tubular atrophy, global sclerosis or inflammatory cell infiltrates. Biopsy proven renal disease were minimal change disease(n=20), focal segmental glomerulosclerosis(n=7), membranous glomerulonephritis(n=2), membranoproliferative glomerulonephritis(n=1), $Henoch-Sch\"{o}nlein$ purpura nephritis(n=6), IgA nephropathy(n=5), poststreptococcal glomerulonephritis(n=2), systemic lupus erythematosus(n=1) and Alport syndrome(n=2). There was a significant relationship between increased cortical echogenicity and global sclerosis or tubular atrophy(P<0.05). But no significant relationship was found between increased cortical echogenicity and interstitial fibrosis, interstitial edema, or inflammatory cell infiltration. In biopsy-proven primary nephrotic syndrome(n=30), no significant relationship was found between the increased conical echogenicity and the interstitial edema, interstitial fibrosis, global sclerosis, tubular atrophy or inflammatory cell infiltration. But there was a significant relationship between increased cortical echogenicity and resistance to corticosteroid (P<0.05). These results suggest that increased cortical echogenicity may be due to tubular atrophy or global sclerosis in patients with proteinuria and may be an effective indicator of resistance to corticosteroid in primary nephrotic syndrome.(J Korean Soc of Pediatr Nephrol 2:26-33, 1998)

Purpose: Alport SD., the most common herectitary rephriris, is a renal disease with rapid progression. Deafness, ocular abnormalities and a specific EM finding may be associated in addition to a family history. We have aralyged retrospectively. Methods: We observed 12 children with Alport syndrome who were diagnosed at Dept. of pediatrics in Kyunghee Univ., College of Medicine, from Apr. 1991 until Jun. 1999. We used four criteria for diagnosis: renal disease, family history, deafness or eye abnormalities, and a specific finding in electron microscopy Results: 2 of 12 patients had all features of the four diagnostic criteria. We could not trace an exact family history in 3 patients, and 6 patients did not exhibit deafness or eye abnormality. One could not have renal biopsy because offer chronic renal failure. Other three criteria were observed in her. The ratio of male to female observed was 1:2 respectively and the mean age of initial renal symptom was 5.6 years. 9 of 12 patients had a family history of renal disease. In the audiogram and ocular examination for 11 of 12 cases, sensorineural hearing loss was observed in 6 and ocular abnormality in 2 cases. In electron microscopic finding, irregular thickness of the capillary basement membranes with lamination of lamina densa and foot process obliteration was noted in 9 of 11 and thin basement membrane with splitting and foot process obliteration was noted in the other 2. The mean period of follow-up was 3 6/12 years. And one patient developed the chronic renal failure until now and had kidney transplantation. Conclusion: For the diagnosis of Alport syndrome, the following four diagnostic criteria are very important : renal disease, family history, deafness or eye abnormalities, and a specific finding on electron microscopy. We expect that more patients can be detected through the analysis of these characteristics.

Purpose: Rapidly progressive glomerulonephritis (RPGN) is a clinicopathologic entity characterized by extensive crescent formation and rapid deterioration of renal function within few months. For better understanding of its clinical course and designing better treatment strategies, a clinicopathological study of childhood RPGN was performed. Methods: The clinical manifestations and pathological findings were reviewed retrospectively in 12 children who were diagnosed as having RPGN by clinical manifestations and renal biopsy during a period from 1991 to 2003. Several clinicopathological parameters were analyzed as prognostic factors. Results: Among a total of 12 patients, 4 were male and 8 were female. The median onset age was 11.5 years(range 5.5-14.6 years), and the median period of follow-up was 25 months(range 7 months-6.6 years). According to the pathological classification, 10 patients (83%) were type II RPGN(immune-complex mediated glomerulonephritis), 2 patients were type III RPGN(pauci-immune glomerulonephritis), and none was type I RPGN(anti-glomerular basement membrane nephritis). All patients were treated with oral steroid in various combinations with methylprednisolone pulse therapy(10 patients, 83%), cyclophosphamide(8 patients, 67%), or plasmapheresis(4 patients, 33%). Clinical outcomes of 12 patients were complete remission in 1(8%), end-stage renal disease in 2(17%), chronic renal insufficiency with persistent proteinuria in 2(17%), and normal renal function with persistent proteinuria in 7(58%) at the last follow-up. Poor prognosis is associated with increased serum creatinine level, severe anemia and younger age at the time of diagnosis. Conclusion: Immune-complex mediated glomerulonephritis is the major cause RPGN in children and most cases showed improvement of renal function with aggressive management. For better understanding of this rare disease, a prospective multicenter study should be done.

Purpose: The prevalence of childhood renal diseases including the nephrotic syndrome in Korea has not been well established. In priority to this point, we analyzed ninety-six nephrotic children of the annual incidence, the ratio of them to all inpatients and estimated incidence of childhood nephrotic syndrome under 15 years of age in Taejon, Korea. Also we classified them by clinical and histopathological findings. Methods: we analyzed the admission and outpatient records retrospectively between June 1986 and December 1998. For the estimation of incidence, we were assisted with three other general hospitals in Taejon Results: The mean annual number and the ratio to inpatients were $7.4{\pm}2.1,\;0.3{\pm}0.11%$ respectively. The latter showed a tendency to decrease during the recent three years. The estimated annual incidences of childhood nephrotic syndrome in Taejon were 5.6 in 1988, 5.5 in 1993 and 4.8 in 1998 per 100,000 for children aged up to 15 years. The mean age of our patients was $6.8{\pm}3.5$ tears, 1-7 years of age was 55 cases(57.3%), and male to female ratio was 3.6:1. By the clinicopathologic classification, 89 cases(92.7%) were classified as primary nephrotic syndrome, and 7 cases(7.3%) as secondary nephrotic syndrome. Among the primary nephrotic syndrome, there was 79.8% of minimal change nephrotic syndrome, focal segmental glomerulosclerosis 11.2%, mesangial proliferation 4.5%, membranoproliferative glomerulonephritis 3.4%, and membranous nephropathy 1.1%. $Henoch-Sch\"{o}nlein$ nephritis was the most frequent of 3 cases in the secondary nephrotic syndrome. Respones to steroid therapy of 71 cases minimal change were classified as non-relapse 22.5%, non-frequent relapse 49.3%, frequent relapse 18.3% and steroid-dependence 9.9%. Conclusion: The estimated incidence of childhood nephrotic syndrome was about 5 per 100,000 for children aged up to 15 years and it showed little changes during 10 years in Taejon, Korea. Our results of clinicopathologic study was little difference from the results reported in other literatures.

Purpose : Henoch-$Sch{\ddot{o}}nlein$ purpura(HSP) is a systemic vasculitis, characterized by cutaneous palpable purpura, gastrointestinal(GI) symptoms, arthritis and renal involvement. In general, the prognosis is determined by GI complication as well as the severity of nephritis. In this study, we analyzed the statistical relationship between the GI symptom and other clinical findings for assessing the prognosis, and evaluated abdominal ultrasonographic findings for early diagnosis of this disease with atypical clinical presentation and early detection of serious GI complications. Methods : One hundred seventy seven patients with HSP in the Department of Pediatrics, Wonkwang University Hospital from January 1994 to June 2004, were enrolled. We retrospectively analyzed charts about clinical and abdominal ultrasonographic findings, and classified our patients into two groups(GI-Sx(-), GI-Sx(+)) for statistical analysis. Results : The ratio of female to male is 1.5 : 1. The peak age incidence was five to eight years in 95 cases(53%). The GI symptoms appeared in 117 cases(66%), which include abdominal pain 115 (98 %), tenderness 45(38%), nausea and vomiting 35(30%), bloody stool 10(8.5%), diarrhea four(3.4%), rebound tenderness four(3.4%), and also intussusception and appendicitis were complicated in five and two cases respectively. GI-Sx(+) group had an increased risk of renal involvement and relapse than the GI-Sx(-) group. But there were no relationships about sex and age incidence, or other clinical and laboratory findings between two groups. Ultrasonographic findings in 98 patients with GI symptoms included small bowel thickening in 70 cases(71%) in which duodenum, jejunum and ileum were involved in 71%, 45.7%, 40% respectively, small bowel dilatation in 41 cases(42%), lymph node swelling in 46 cases(47%), and ascites in 25 cases(25.5%). Conclusion : GI symptoms in patients with HSP suggested increased risk of renal involvement and relapse. Abdominal ultrasonography could be helpful in the early diagnosis on atypical clinical presentation and early detection of serious GI complication in these patients.

Purpose : The isolated microscopic hematuria is the most common abnormality detected by school urinary screening, but there is no consensus about the range of investigations and long-term outcomes of isolated hematuria in children yet. This study aims to elucidate the prognosis of hematuria and the range of diagnostic studies by follow-up results. Methods : Students with isolated hematuria who were referred to the Department of Pediatrics, Asan Medical Center from Aug. 1990 to Feb. 2004 were analysed retrospectively. Cases that presented Through significant proteinuria(>250 mg/day), other symptoms of nephritis or renal dysfunction (creatinine clearance <85 mL/min/$1.73m^2$) were excluded. Follow-up was done every six months with checking urinalysis, serum creatinine, protein and albumin. When albuminuria was detected, 24 hour urine protein was checked. Renal biopsy was done when urine protein was over 500 mg/day. Results : A total of 331 students were enrolled in this study. There were 157 males and 174 females. The mean age at presentation was $9.9{\pm}2.3$ years(7-15 years) and mean follow-up period was $2.2{\pm}1.6$ years(1-10 years). Seventy five(22.7 percent) patients showed the resolution of microscopic hematuria. The mean resolution period was $2.6{\pm}1.7$ years(1-8 years). Eight(2.4 percent) patients developed significant proteinuria and renal biopsy was done in four of them. Two cases of mild IgA nephropathy and two of minimal change were detected. None of them developed hypertension. At the end of the follow-up, renal function had remained stable in all subsets of patients. Conclusion : The prognosis of isolated microscopic hematuria was good. This study suggests that invasive studies including renal biopsy are not necessary and a regular follow-up of urinalysis is enough for children with isolated microscopic hematuria.
