Clin Exp Pediatr. 2004;47(7):735-739.   Published online July 15, 2004
Purpose : Respiratory distress syndrome(RDS) is caused by a deficiency of pulmonary surfactant, which is a lipoprotein complex. Both low levels of surfactant protein A(SP-A) and SP-A alleles have been associated with RDS. However, the genes underlying susceptibility to RDS are insufficiently known. The candidate-gene approach was used to study the association between the SP-A gene locus and RDS in...

Pathophysiology of Persistent Pulmonary Hypertension of the Newborn
Yong Hoon Jun
Clin Exp Pediatr. 2004;47(7):707-715.   Published online July 15, 2004
Persistent pulmonary hypertension of the newborn(PPHN) is a disorder characterized by persistence of the pattern of fetal circulation after birth due to a sustained elevation of pulmonary vascular resistance. The two primary events in the pathophysiology of neonatal pulmonary hypertension are hypoxic pulmonary vasoconstriction(HPV) and hypoxic pulmonary vascular remodeling(HPR). Chronic hypoxemia may cause increased muscularity of the pulmonary arteries and...

Angiotensin Converting Enzyme Inhibition Modulates Mitogen Activated Protein Kinase Family Expressions in the Neonatal Rat Kidney
Byung Min Choi, Mee-Hye Oh, Kee Hwan Yoo
Clin Exp Pediatr. 2004;47(3):325-331.   Published online March 15, 2004
Purpose : In a developing kidney, the renin-angiotensin system(RAS) is markedly activated and is thought to play an important role in postnatal renal growth and maturation. We previously demonstrated that angiotensin converting enzyme(ACE) inhibition in a developing rat kidney increases apoptosis and decreases its related gene expressions, which may account for renal growth impairment. Among the mitogen-activated protein kinases(MAPK) family...
