Ju Hee Seong, Hyeon Joo Lee, Hyun Kee Hong, Chong-Woo Bae, Yong-Mook Choi
Clin Exp Pediatr. 2003;46(11):1080-1084.   Published online November 15, 2003
Purpose : To compare perinatal characteristics, clinical courses, and overall morbidity between respiratory distress syndrome(RDS) with patent ductus arteriosus(PDA) and RDS without PDA in neonates. Methods : Eighty-three neonates who were diagnosed and treated for RDS in the neonatal intensive care unit(NICU) from Jan. 2000 to Dec. 2002 were included in this study. RDS was complicated with PDA(group A) in...
Case Report
A Case of Hemolytic Disease in a Newborn Due to Anti-Jkb
Dong-Kyun Park, Young-Min Kim, Chong-Woo Bae, Yong-Mook Choi, Woo-In Lee
Clin Exp Pediatr. 2003;46(7):718-721.   Published online July 15, 2003
The isoimmune hemolytic disease of newborn due to the incompatibility of minor blood groups is characterized by progressive neonatal hyperbilirubinemia and anemia caused by the IgG antibody transmitted from the mother to the fetus. Recently we had a case of hemolytic disease in a newborn due to anti-Jkb. There were no ABO and Rh(D) incompatibilities between mother and baby. The...

A Study of Surface Physical Properties of New Surfactant Using Synthetic Peptides of Surfactant Protein-B
Chong-Woo Bae, Yong-Mook Choi, Joo Hyun Kang, Sang-Chul Lee, Kil Lyong Kim, Kyung-Soo Hahm
Clin Exp Pediatr. 2000;43(8):1059-1067.   Published online August 15, 2000
Purpose : To produce a new generation of artificial pulmonary surfactant(PS), surfactant protein (SP)-B from human PSwas isolated, and the amino acid sequences of these proteins were studied. Artificial peptides of human SP-B were synthesized. New artificial PS preparations which were composed of phospholopids and two artificial synthetic SP-B peptides were made, and the surface physical properties of these new PS preparations were tested. Methods...
A Comparative Study of Red Blood Cell Indices and Anemia by Feeding Patterns
Pill-Jin Shin, Chong-Woo Bae, Yong-Mook Choi
Clin Exp Pediatr. 1999;42(8):1104-1110.   Published online August 15, 1999
Purpose : Iron-deficiency anemia is the most common nutritional deficiency in young infants. This study was designed to determine feeding patterns in infants, and determine a correlation between feeding patterns and incidence of anemia. Methods : This study was conducted by taking blood tests (hemoglobin, hematocrit, and red cell indices) by venipuncture with the electronic counters from 221 infants aged 9-12...

Nationwide Survey on Group A beta-Hemolytic Streptococcal Carrier Rate in Normal Korea School Children in 1996
Sung-Ho Cha, Yong-Mook Choi, Sei-Won Yang, Dong-Hwan Lee, Chong-Guk Lee, Chang-Ho Hong
Clin Exp Pediatr. 1998;41(5):585-592.   Published online May 15, 1998
Purpose : The accuracy of bacteriologic diagnosis of beta-hemolytic streptococcal pharyngotonsillitis depends on the degree of carrier rate in that area. It is the purpose of this study to obtain the carrier rate from seven different areas and to find results and epidemiologic factors. Methods : Throat swab was obtained from the tonsillar fossa of normal school children during March through...
Clinical Study and Diagnostic Value of the Lung Perfusion Scan in Foreign Body Aspiration
Gyo-Dang Koo, Young-Ho Rah, Chong-Woo Bae, Sa-Jun Chung, Yong-Mook Choi
Clin Exp Pediatr. 1998;41(1):74-80.   Published online January 15, 1998
Purpose : Early diagnosis of foreign body aspiration and removal of the inhaled material may save the patient from chronic illness and may prevent serious complications. At present the diagnostic problems of bronchial foreign bodies are being solved by using the lung scanning technique. Therefore, we investigated the clinical study and diagnositic value of the lung perfusion scan in foreign body aspiration. Methods : Eighteen...
The Correlation between a Semi-quantitative ASO(Antistreptolysin O) Assay by Rantz-Randall and a Quantitative ASO Assay by Nephelometry
Sung-Keun Park, Seok-Hee Ahn, Jung-Woo Lee, Byoung-Soo Cho, Sung-Ho Cha, Yong-Mook Choi
Clin Exp Pediatr. 1997;40(12):1670-1674.   Published online December 15, 1997
Purpose : Accurate diagnosis and prompt treatment of infection with Streptococcus pyogenes (group A streptococci) is required as it may cause many complications, and chronic serious sequelae, acute rheumatic fever and acute glomerulonephritis. Recently, the assay methods of ASO concentration tend to be changed into quantitatively from semi-quantitative or qualitative methods in this country. We would like to know relationships and degree of concurrences between...
Role of Serum Ca and 1,25(OH)2D3 as Predictor in Bone Metabolism Abnormality by Chronic Medication of Anticonvulsant
Ho-Soo Kim, Hyun-Ho Kang, Sa-Jun Chung, Yong-Mook Choi
Clin Exp Pediatr. 1997;40(11):1567-1571.   Published online November 15, 1997
목 적 : 항경련제의 장기복용에 의하여 저칼슘혈증, 구루병, 골연화증 등의 골대사 이상은 성 장기 소아의 중대한 문제점이 될 수 있으므로 조기발견 및 치료가 중요하다. 이에 본 저자들은 골대사 이상의 예측을 위한 지표로서 혈청 Calcium(이하 Ca), 1,25(OH)2D3에 대하여 연구를 시행하였다. 방 법 : 경희의대 소아과에서 경련성 질환으로 진단 받고 6개월 이상 항경련제를 복용한 48 명을 대상으로 하였다. 이들중 항경련제 단독복용은 37명, 두 가지 이상의 혼합복용군은 11명 이었으며,...
Surfactant Protein SP-A, B, and C: Purification and Biochemical Characterization
Chong-Woo Bae, Yong-Mook Choi, Joo Hyun Kang, Kil Lyong Kim, Kyung Soo Hahn
Clin Exp Pediatr. 1996;39(2):218-229.   Published online February 15, 1996
Purpose : Several kinds of exogenous pulmonary surfactants (SF), either synthetic or animalderived, are being used for the replacement therapy in respiratory distress syndrome (RDS) of newborn, especially in premature infants, and improved the neonatal mortality and morbidity. Because synthetic preparations are lack of surfactant protein (SP) and animal-derived preparations cause immunogenecity of heterogenous SP, there have been great necessity for the development of next...
Sequential Changes of Chest Radiographic Finding after Exogenous Surfactant Replacement Therapy in Neonates with RDS

Clin Exp Pediatr. 1995;38(2):151-158.   Published online February 15, 1995
Purpose : The chest radiograph is useful and reliable in assessing the severity and progres-sion of neonatal respiratory distress syndrome. To evaluate the effect of exogenous surfactant r eplacement therapy, we performed sequential observation of chest radiogratphic findings in ne-onates with respiratory distress syndrome. Methods : Two groups of infant with RDS in mechanical ventilation therapy were studied. S-urfactant(S-Tx) group(n=36) was...
