Eosinophil disorders
Sun Young Kim
Clin Exp Pediatr. 2009;52(6):643-648.   Published online June 15, 2009
Blood eosinophilia can be classified as either familial or acquired. Familial eosinophilia is a rare autosomal dominant disorder characterized by a stable eosinophil count. Acquired eosinophilia is classified further into a primary or secondary phenomenon depending on whether eosinophils are considered integral to the underlying disease. Primary eosinophilia is considered clonal in the presence of either a cytogenetic abnormality or...

Renal cell carcinoma (RCC) arising from epithelial cells of the renal tubules is a highly aggressive and malignant tumor in all ages; however, it rarely occurs in children. the standard treatment for RCC is radical nephrectomy with lymph node dissection when the tumor is localized and can be completely resected. Adjuvant chemotherapy, radiotherapy, and immunotherapy are used for pediatric patients...

Hye Young Jin, Kyoung In Kang, Sun Young Kim, You Sook Youn, Joon Won Kang, Deog Yeon Jo, Kye Chul Kwon, Kyung Duk Park
Clin Exp Pediatr. 2008;51(1):73-77.   Published online January 15, 2008
Purpose : p16 gene, mapped to the 9p21 chromosomal region, has emerged as a candidate tumor suppressor gene in human neoplasm. It is an inhibitor of cyclin-dependent kinase and inhibits Rb phosphorylation. In a variety of tumors including childhood acute lymphoblastic leukemia (ALL), deletion and/or mutation of the p16 gene has been found. Despite their high frequency, the prognostic importance...
Effect of intravenous deferoxamine in multiply transfused patients
Sang Min Oh, Joon Won Kang, Sun Young Kim
Clin Exp Pediatr. 2007;50(12):1225-1230.   Published online December 15, 2007
Purpose : Multiple transfusions in patients with chronic anemia can result in excessive iron deposition in tissues and organs. Effective iron chelation therapy in chronically transfused patients can only be achieved when iron chelators remove sufficient amounts of iron equivalent to those accumulated in the body from transfusions, thus leading to maintain body iron load at a non-toxic level. This...

Clin Exp Pediatr. 2006;49(4):431-438.   Published online April 15, 2006
목 적 : 새로운 암억제 유전자로 알려진 IGFBP-3의 주요 기능은 IGF-I과 IGF-II와 결합을 하여 IGF의 기능을 조절하는 IGF dependent mechanism과 IGFBP-3 자체가 IGF와 결합과는 무관하게 세포의 apoptosis를 유도하는 IGF independent mechanism이 보고되었다. 암억제 유전자 p53의 대표적인 항암기전의 하나는 직접 IGFBP-3의 발현을 증가시키며, 발현된 IGFBP-3는 암세포의 apoptosis를 유도시킨다. IGFBP-3의 항암작용은 보고되었지만, IGFBP-3의 변역 후 변형에 의한 항암기전은 전혀 밝혀져 있지 않다....
