Regulatory T Cells and Allogeneic Transplantation
Dae Chul Jeong
Korean J Pediatr. 2004;47(9):919-925.   Published online September 15, 2004
Allogeneic organ or hematopoietic stem cell transplantation(HSCT) is the treatment of choice for end-stage organ diseases or various hematologic disorders. The induction of alloantigen specific T cell tolerance and its maintenance are critical for preventing immune responses, including graft rejection or graft-versus-host disease(GVHD) in allogeneic transplantation. CD4＋ T cells are classified as immune functions : Th1 CD4＋ cells for cellular...

Acquired Thyroid Disorders in Childhood
Ho-Seong Kim
Korean J Pediatr. 2004;47(9):926-932.   Published online September 15, 2004
Thyroid hormones influence growth and development, oxygen consumption, heat production, nerve function, and metabolism, thus play a critical role as a regulator of nervous system myelination, of growth and of puberty. Disorders affecting thyroid function may cause irreversible and permanent nervous system damage and developmental delay, especially in early infancy. Appropriate medical care of children with thyroid disorders requires refined...

Synergistic Cytotoxicity of Arsenic Trioxide and Sulindac Against Neuroblastoma
Du Young Choi
Korean J Pediatr. 2004;47(9):1002-1007.   Published online September 15, 2004

Like APL cells, neuroblastoma(NB) cells are thought to be arrested at an early stage of differentiation, and can respond with retinoic acid treatment. Sulindac, a nonsteroidal antiinflammatory drug, was reported to induce antitumor activity...

Korean J Pediatr. 2004;47(9):1020-1023.   Published online September 15, 2004
The deficiency of enzyme hypoxanthine-guanine phosphoribosyltransferase(HPRT) results in hyperuricemia and subsequently manifests in diverse symptoms. Lesch-Nyhan syndrome is a disorder characterized by hyperuricemia, mental retardation, choreoathetosis, spasticity and self-mutilation, resulting from complete deficiency of the enzyme, whereas partial deficiency of the enzyme shows symptoms of milder forms more often without abnormal neurologic signs. A 7-year-old boy with normal growth and...
