Chang Hee Han, Jun Ho Huh, Un Seok Nho, Byung Ho Choi, Myung Chul Hyun, Sang Bum Lee
Clin Exp Pediatr. 1999;42(6):807-816.   Published online June 15, 1999
Purpose : To assess wall motion of the left ventricle in the various forms of congenital heart disease and to select appropriate methods by which to gauge left ventricular wall motion. Methods : We evaluated left ventricular function, including volume, global ejection fraction, and regional wall motion(Centerline method, Local Ejection Fraction, Curved Perimeter method and Radial method). The evaluation was done...

Transient tachypnea of the newborn(TTN) is a benign self-limited disease characterized by early onset and rapid recovery of tachypnea although it may occasionally have a more prolonged and protracted course. A retrospective clinical study was mad on 29 neonates with TTN admitted to NICU of Pohang St. Mary's Hospital from January 1992 to June 1993. The results were as follows: 1) TTN(36.2%) was...

Clin Exp Pediatr. 1991;34(3):303-310.   Published online March 31, 1991
The reliability of electrocardiographic detection of serum ionized Ca level was studied in 13 preterm and 32 full term infants. The concentration of ionized Ca was measured with a new ion-selected electrode, NOVA SP4 (NOVA Biomedical, Waltham, MA USA). The Q-oTc interval correlated with total Ca (r=o.553, p<0.01) and ionized Ca (r= -0.435, p< 0.01) but the Q-Tc interval did not correlate with total and...
Therapeutic Effect of Iron Deficiency Anemia.
Dong Suk Lee, Chang Hee Han, Kun Soo Lee
Clin Exp Pediatr. 1990;33(6):799-806.   Published online June 30, 1990
A prospective study was conducted to see the therapeutic effect of iron deficiency anemia on a different oral iron doses. Studied patients consisted of 48 children with iron deficiency anemia who were admitted to our Pediatric Department during January 1988 - September 1989. Three groups were consisted with Group A (element iron dose 3 mg/kg/d, 16 cases), Group B (3 mg/kg/d with vitamin C...
