Kyung Ha Ryu, Eun Ae Park, Kyung Hyo Kim, Gyung Hee Kim
Clin Exp Pediatr. 1998;41(1):12-18.   Published online January 15, 1998
Purpose : The neonate is susceptible to severe and overwhelming bacterial infections. One of the most important deficiency in the neonatal host defense system seems to be quantitative and qualitative deficiency of the myeloid and the phagocytic system. Granulocyte colony-stimulating factor(G-CSF) has been shown to induce neutrophilia and enhance mature effector neutrophil function. We examined serum levels of G-CSF in...

Dermatophagoides Pteronyssinus Specific IgG-subclass Antibodies in Allergic Children
Soo Ja Hwang, Kyung Hyo Kim, Young Mi Hong
Clin Exp Pediatr. 1997;40(5):701-707.   Published online May 15, 1997
Purpose : Although immunoglobulin E play a major role in immediate hypersensitivity reactions, some reaginic activity is associated with IgG. Part of the reaginic activity is associated with IgG1, IgG4. In contrast with this reaginic activity of IgG4, allergen-specific IgG4 antibody is allergen neutralizing antibody and contribute to the benificial effect of immunotherapy. The role of specific IgG antibody in allergic...

Clin Exp Pediatr. 1997;40(2):173-180.   Published online February 15, 1997
Purpose : Enzyme immunoassay (EIA) is now a widely used technique. We have described the application of enzyme amplification (sensitive ELISA) in the field of immunoassays of pediatric population. There are two issues with the sensitive ELISA. First is that one can minimize the serum volume, an important concern for pediatricians. The second is the problem of background signal. We demonstrate that it...

Kyung Hyo Kim, John Linton, Yunsop Chong, Dong Soo Kim
Clin Exp Pediatr. 1993;36(8):1107-1115.   Published online August 15, 1993
The immune response to M. tuberculosis engages T-cell medicated reactions which determine the degree of resistance and also the clinical pattern of disease. Although antibodies produced by the infected host have yet no proven protection, they are appilicable for alternative diagnostic tests in tuberculosis. Preparation of purified antigens from Mycobacteria with specific antigenic determinants would improve serological diagnosis in tuberculosis. The...

Kyung Hyo Kim, Dong Soo Kim
Clin Exp Pediatr. 1992;35(8):1059-1065.   Published online August 15, 1992
Tuberculosis has been an important world-wide infectious disease. The prevalence of radiologically active tuberculosis was 1.8% of population in Korea. Probably the most important aspect of the pathogenesis of tuberculosis is the nature and specificity of the response of the immune system to the antigens of tubercle bacilli. Preparation of purified antigens from Mycobacteria with specific antigenic deterninants would improve...
