Purpose

Previous studies suggest that the concentration of 25-hydroxyvitamin D [25(OH)D] in cord blood may show an inverse association with respiratory tract infections (RTI) during childhood. The aim of the present study was to examine the influence of 25(OH)D concentrations in cord blood on infant RTI in a Korean birth cohort.

Methods

The levels of 25(OH)D in cord blood obtained from 525 Korean...

Umbilical cord blood transplantation
Hong Hoe Koo, Hyo Seop Ahn
Clin Exp Pediatr. 2012;55(7):219-223.   Published online July 17, 2012

Since the first umbilical cord blood transplantation (CBT) in 1998, cord blood (CB) has now become one of the most commonly used sources of hematopoietic stem cells for transplantation. CBT has advantages of easy procurement, no risk to donor, low risk of transmitting infections, immediate availability and immune tolerance allowing successful transplantation despite human leukocyte antigen disparity. Several studies have...

Hematopoietic stem cell transplantation in children with acute leukemia: similar outcomes in recipients of umbilical cord blood versus marrow or peripheral blood stem cells from related or unrelated donors

Clin Exp Pediatr. 2012;55(3):93-99.   Published online March 16, 2012
Purpose

This study compared outcomes in children with acute leukemia who underwent transplantations with umbilical cord blood (UCB), bone marrow, or peripheral blood stem cells from a human leukocyte antigen (HLA)-matched related donor (MRD) or an unrelated donor (URD).

Methods

This retrospective study included consecutive acute leukemia patients who underwent their first allogeneic hematopoietic stem cell transplantation (HSCT) at Samsung Medical Center between...

A pilot study of neuroprotection with umbilical cord blood cell transplantation for preterm very low birth weight infants

Clin Exp Pediatr. 2007;50(9):882-890.   Published online September 15, 2007
Purpose : Preterm very low birth weight infant have high rate of adverse neurodevelopmental sequale. Recently, there have been lots of reports that human umbilical cord blood transplantation ameliorates functional deficits in animal models as hypoxic ischemic injury. This pilot study was undertaken to determine the clinical efficacy and safety of autologous umbilical cord blood cell transplantation for preventing neurodevelopmental...
Umbilical Cord Arterial Concentrations of Isoprostane(8-iso-PGF2α) in Newborn Infants
Kun Song Lee, Yoon Hee Ji, Young Pyo Chang
Clin Exp Pediatr. 2003;46(9):865-870.   Published online September 15, 2003
Purpose : We measured the umbilical cord arterial concentrations of isoprostane(8-iso-PGF2α) and intended to decide whether the umbilical cord arterial concentrations of isoprostane could be used as a useful parameter for lipid peroxidation in newborn infants. Methods : The isoprostane and malondialdehyde(MDA) concentrations of the umbilical cord were measured by enzyme immunoassay and TBARS(thiobarbituric acid reactive substance) assay in 33...
The Correlation between CD34+ Cell and Nucleated RBC Counts in Human Cord Blood
Seong Man Lee, Kyu Chan Kim, Sang Woo Kim
Clin Exp Pediatr. 1996;39(10):1422-1428.   Published online October 15, 1996
Purpose : Human umbilical cord blood as a potential source of hematopoietic stem cell for stem cell transplantation in children has recently been advocated. Clinical application of cord blood transplantation, however, requires adequate blood volume and number of stem cells. Currently, the number of stem cells in the cord blood is usually measured by flowcytometry, which requires strict quality control and high costs. Here,...
Stem Cell Transplantation in Umbilical Cord Blood(I) Expansion Effects of Stem Cells in Umbilical Cord Blood with Various Hematopoietic Growth Factors
Kyung Ha Ryu, Myung Hee Chung
Clin Exp Pediatr. 1995;38(5):675-684.   Published online May 15, 1995
Stem cell transplantation is used for the patients lacking the capability of production of hem-atopoitic cells. Recently, there have been a few studies using the umbilical cord blood as a sou-rce of stem cells, however it remains unclear whether umhhilical cord blood contains sufficient amount to reconstitute the patient. Our study was designed to know that umbilical cord blood is proper...
