Clin Exp Pediatr. 1996;39(9):1260-1270.   Published online September 15, 1996
Purpose : Pertussis, a respiratory tract infection caused by Bordetella pertussis, is an important cause of morbidity in children. But diagnosis of pertussis is often delayed because of late development of typical symptoms and difficulties in culture. There has been no bacteriologically confirmed case of B. pertussis infection in Korea. Lower respiratoy tract may be involved in pertussis. We performed the polymerase chain reaction(PCR)...

Plasma Somatomedin C Levels in Normal Children
Bo Young Yun, Hoan Jong Lee
Clin Exp Pediatr. 1992;35(11):1493-1500.   Published online November 15, 1992
Somatomedin C, the insulin-like growth factor I is suggested to mediate the growth-promoting effect of growth hormone. Sm-C, mostly bound to plasma protein forming an IGF-I protein complex, is slowly cleared from plasma and thus its plasma concentration is quite constant. A single sampling of blood for Sm-C is sufficient for the measurement of its concentration. For the evaluation of...
