The effects of early allergen/endotoxin exposure on subsequent allergic airway inflammation to allergen in mouse model of asthma
Yeong-Ho Rha, Sun-Hee Choi
Clin Exp Pediatr. 2010;53(4):481-487.   Published online April 15, 2010
Purpose : Recently many studies show early exposure during childhood growth to endotoxin (lipopolysaccharides, LPS) and/or early exposure to allergens exhibit important role in development of allergy including bronchial asthma. The aim of this study was to evaluate the role of endotoxin and allergen exposure in early life via the airways in the pathogenesis of allergic airways inflammation and airway hyperresposiveness...

Stevens-Johnson syndrome (SJS) presents with widespread blisters, erythematous or purpuric macules, and one or more mucous membrane erosions. Various etiologic factors, including infection, vaccination, drug administration, systemic diseases, physical agents, and food have been implicated as causes of SJS. Mycoplasma pneumoniae is the most common infectious agent to cause SJS in children. In recent literature, M. pneumoniae-induced SJS with mucositis...
A case of recurrent respiratory infection resulting from a congenital anomaly of the bronchial tree tracheal bronchus
Ah-Reum Choi, Sun-Hee Choi, Seong-Wan Kim, Dong-Wook Sung, Yeong-Ho Rha
Clin Exp Pediatr. 2008;51(6):660-664.   Published online June 15, 2008
The term tracheal bronchus refers to an abnormal bronchus that comes directly off of the lateral wall of the trachea (above the carina) and supplies ventilation to the upper lobe. Tracheal bronchi occur almost exclusively on the right trachea and are associated with other congenital anomalies. In addition, tracheai bronchus may be related to other inflammatory conditions with persistent wheezing,...

Relationship between exhaled nitric oxide and pulmonary function test in children with asthma
Han-Seok Ko, Sung-Hoon Chung, Yong-Sung Choi, Sun-Hee Choi, Yeong-Ho Rha
Clin Exp Pediatr. 2008;51(2):181-187.   Published online February 15, 2008
Purpose : Asthma is characterized by reversible airway obstruction and bronchial hyperresponsiveness result from airway inflammation. Fraction of nitric oxide in expired air (FeNO) has recently been investigated as a noninvasive measure of airway inflammation. FeNO has been reported to correlate with induced sputum eosinophilia and methacholine challenge test that it is represent severity of asthma. The purpose of this...
Serological Analysis and Epidemiologic Characteristics of Group A Streptococci in Seoul(1998-2000)
Sun-Hee Choi, Yun-Ho Kim, Sung-Ho Cha, Ki-Sang Kim, Young-Hee Lee
Clin Exp Pediatr. 2002;45(11):1368-1372.   Published online November 15, 2002
Purpose : Group A streptococci have a cell wall which consists of M protein and T protein. T protein is known to be helpful in the understanding of the epidemiology of group A streptococci. To study the epidemiologic characteristics, we serotyped T protein of group A streptococci obtained from patients admitted to hospitals, or who visited OPD in five districts...
