Significance of Polymerase Chain Reaction Test for Diagnosis of Mycoplasma pneumoniae Pneumonia
Hae-kyung Lim, Young-Hun Chung
Clin Exp Pediatr. 1999;42(2):173-179.   Published online February 15, 1999
Purpose : Mycoplasma pneumoniae is a common cause of lower respiratory disease, especially in children and young adults. The diagnosis, in most cases, is confirmed by serology. M. pneumoniae is difficult to culture because of its fastidious nature, and growth is too slow for diagnostic use. In this prospective study, the sensitivity and specificity of the PCR assay was evaluated...
A Study on Spirometry Pattern of Normal Children
Hyoung-Shin Lee, Young-Hun Chung
Clin Exp Pediatr. 1997;40(9):1242-1249.   Published online September 15, 1997
Purpose : Pulmonary function test is one of the most important tools in the management of patients with respiratory tract diseases and allergic diseases. In recent years pulmonary function tests have had a wide application in clinical pulmonary diseases. But, there were a few trials of pulmonary function test in normal children. So We performed spirometry-based pulmonary function tests of normal children. Methods : We...
Studies on the B Cell Proliferation and Differentiation Factors in Human B Cell System
Kwang-Ju Lee, Young-Hun Chung, Jae-Ho Lee
Clin Exp Pediatr. 1994;37(10):1386-1396.   Published online October 15, 1994
We have studied the function of lymphokines on human tonsillar B cell proliferation and differentiation. B cells were stimulated with Staphylococcus aureus Cowan1(SAC) or anti-μ bead. The followings showed the results of this study. 1) In B cell activation, SAC induced B cell DNA synthesis but anti-μ bead did not. SAC could activate and proliferate B cells. Minimal number of B cells...
