Purpose : FSGS do not respond well to any kind of therapy and gradually progress to end-stage renal disease. This study was conducted to investigate the difference of protein expression between MCNS and FSGS as a preliminary study for understanding the pathophysiology of FSGS. Methods : Renal biopsy samples of MCNS and FSGS were obtained, which was diagnosed by one pathologist. They were solubilized with a conventional extraction buffer for protein extraction. The solution was applied on immobilized linear gradient strip gel (pH 4-7) using IPGphor system. Silver staining was carried out according to standard method. Protein identification was done by searching NCBI database using MASCOT Peptide Mass Fingerprint software. Results : The differences in protein expressions between MCNS and FSGS were shown by increased or decreased protein spots. Most prominently expressed spot among several spots in FSGS was isolated and analyzed, one of which was glutathione S-transferase (GST) P1-1, whereas it was not found in MCNS. So GSTP1-1 was considered as the one of the key biomarkers in pathogenesis of FSGS. Conclusion : This result would be helpful in diagnosing FSGS and researching FSGS. Further studies for glutathione S-transferase P1-1 might be necessary to elucidate the mechanisms regarding FSGS.

Purpose : Corticosteroid has been used as the mainstay therapy of childhood NS. But SIO is one of the serious complications of long-term steroid therapy, especially in growing children. Recently calcium, calcitonin, PTH, vitamin D and bisphosphonate has been used to treat or prevent SIO in adult, which is rare in children with NS. We studied the effect of $1{\alpha}-(OH)D_3$ and Pamidronate on SIO using dual energy X-ray absorptiometry (DEXA). Patients and methods : We studied thirty patients who admitted in the Dept. of Pediatrics of Kyung Hee Medical Hospital with NS. All patients was received longterm steroid therapy. There was no history of bone, liver, or endocrine disease. The samples, serum protein, albumin, BUN, creatinine, calcium, phosphorus, and BMD were obtained before and the six months after the dose of $1{\alpha}-(OH)D_3$ and Pamidronate, respectively Results : The mean age was $6.9{\pm}3.3\;and\;6.5{\pm}2.5$ years old. The mean duration of steroid therapy was $28.8{\pm}1.8\;and\;27.6{\pm}1.0$ months. The changes of serum protein, albumin, BUN, creatinine, calcium and phosphorus level between pre-treatment and post-treatment did not show statistical significance in both $1{\alpha}-(OH)D_3$ and Pamidronate treatment group. However, BMD was increased in both from $0.472{\pm}0.12\;and\;0.457{\pm}0.10\;g/cm^2\;to\;0.533{\pm}0.12$ and $0.529{\pm}0.09\;g/cm^2$ after treatment. (P<0.05) Conclusion : Both $1{\alpha}-(OH)D_3$ and Pamidronate appears to be effective in treating and preventing SIO in children with nephrotic syndrome requiring long-term steroid therapy.

Purpose: We studied to find out apo-E genotype polymorphism in minimal change nephrotic syndrome(MCNS) and IgA nephropathy(IgAN) and to determine the relationship between apo-E genotype and clinical course of MCNS. Materials and Method: 43 MCNS patients and 15 IgAN patients were examined for apo-E polymorphism. 50 healthy blood donors were examined for apo-E genotype as control. Genomic DNA was prepared front peripheral blood leukocytes according to standard procedures. Results: As compared with control group, e4 allele frequency was significantly increased in MCNS (p<0.01). However, in IgAN e2 allele frequency, however, was 2.6 times higher than normal control (P<0.01). The frequency of e4 allele of frequent relapser group was 4.6 times higher than normal control and was 2 times higher than infrequent relapser group. Conclusion: We think that apo-E typing might be one of the parameters, which should be considered to predict the course of MCNS in children. MCNS with risky HLA profile and E4/4 genotype could indicate the need for a longer steroid administration. And apo-E genotype needs to be considered for the evaluation of therapeutic responses to other drugs. (J, Korean Soc Pediatr Nephrol 2001 ; 5 : 87-99)

Purpose: Propose model to diagnose and assess National Defense Industry and quality management by investigating and analyzing established standard model. Methods: Research on established internal model including MB, EQA and JQA model and make standard index for quality index extraction and quantitative index to test objectively for internal state. Results: Extract advantage and disadvantage by performance of National Defense Industry level diagnose and build foundation for quality management policy and road map. Conclusion: Due to result of diagnostic assesment of quality management of national defense industry, dependability, SCQM and safety part shows vulnerability and require improvement and support.
