Jeong Deok Hong, In Seok Lim
Clin Exp Pediatr. 2012;55(4):136-142.   Published online April 30, 2012
Purpose

Urinary excretion of N acetyl-beta-D glucosaminidase (NAG) and β2-microglobulin (β2-M) was increased in the presence of proximal tubular damage. Based on these urinary materials, we investigated the ability of expecting renal function in chronic glomerular diseases. In this study, we evaluated the relationship between glomerular filtration rate (GFR) urinary NAG, and urinary β2-M.

Methods

We evaluated 52 children with chronic kidney disease...

Comparison of various methods of glomerular filtration rate measurements in children
Na Mi Lee, In Seok Lim
Clin Exp Pediatr. 2009;52(9):999-1004.   Published online September 15, 2009

Purpose:Glomerular filtration rate (GFR) is a fundamental parameter in assessing renal function and predicting the progression of chronic renal disease. Because the use of serum creatinine has several disadvantages, many studies have investigated the use of cystatin C for estimating GFR. We compared creatinine clearance and GFR with formulas using serum creatinine and cystatin C. Methods:We retrospectively analyzed 211 patients...
The Relation between Obesity and Glomerular Filtration Rate in Children and Adolescents
Youngsu Jung, Dongwoon Kim, Inseok Lim
Clin Exp Pediatr. 2005;48(11):1219-1224.   Published online November 15, 2005
Purpose : The prevalence of obesity in children and adolescents has been rising rapidly in Korea because of changes of diet and lifestyle. As with adults, obesity in children and adolescents can cause diabetes mellitus, hyperlipidemia, cardiovascular diseases and renal diseases. The aim of the present study is to examine the relation of obesity, glomerular filtration rate(GFR) and serum cystatin...
The Value of Serum Concentration of Cystatin C as a Marker for Glomerular Filtration Rate in Children and Adolescents
Young-Su Jung, In-Seok Lim
Clin Exp Pediatr. 2005;48(6):614-618.   Published online June 15, 2005
Purpose : Cystatin C has been proposed for the assessment of glomerular filtration rate, being more accurate than creatinine determination. We measured serum cystatin C concentrations in the pediatric population, and analysed the correlation between cystatin C and glomerular filtration rate. Methods : Cystatin C and creatinine were measured by the particle enhanced nephelometric immunoassay and Jaff method, respectively, in...
Estimation of Glomerular Filtration Rate from Plasma Creatinine and Height in Premature and Fullterm Neonates.
Yeong Jee Kim, Keun Lee
Clin Exp Pediatr. 1986;29(7):723-729.   Published online July 31, 1986
In clinical practice, creatinine clearance(Ccr) remains the most commonly used laboratory assessment of glomerular function despite methodological and technical problems of urine collection. Schwartz et al. in 1976，reported that an accurate estimate of glomerular filtration rate (GFR) could be obtained from the simple determinations of plasma creatinine (Per) and body length(L):GFR(ml/min/1.73cm2)=k• L(cm)/Pcr(mg/100ml), (k=constant). The purpose of this investigation is to compare...
