Mycobacteria cause diseases which occur the world over and whoich carry a considerable burden in morbidity, mortality and social problems. A battery of monoclonal antibodies specific for mycobacterial antigens would provide a useful tool for rapid diagnosis of mycobacterial diseases. Fourtenn monoclonal antibodies to perchloric acid soluble antigne of M. tuberculosis were produced. Immunoglobulin isotypes of monoclonal antibodies were ten... |
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... |
Systemic lupus erythematousus(SLE) is a disease affecting blood vessels and connective tissue, which are damaged by deposition of pathogenic autoantibodies and immune complexes.Although a complex disease, SLE provides a number of insights into autoimmune pathogenesis. Autoimmune disease, in general, is characterized by B cell hyperactivity which results in hypergammaglobulinemia and production of a variety of autoantibodies reactive to organ-nonspecific antigens... |
Kawasaki disease has been known as an acute febrile mucocutaneous lymph node syndrome since 1967. But its definite pathophysiology still remains unclear. In order to study the immunologic basis for immunologic abnormalities in this disease, we studied the level of soluble interleukin-2 receptor (sIL-2R), interleukin-6 (IL-6) and C-reactive protein (CRP) at the acute and convalescent phases of the disease, comparing... |
Severe combined immunodeficiency disease is caused by a group of genetic disease characterized by abnormal function of T and B lymphocytes. The treatment of choice for severe combined immunodeficiency disease is a HLA mached bone marrow transplant, but transplantation of cultured thymus epithelium was used to treat severe combined immunodeficiency disease in case of that mached, related bone... |

Maximal augmentation was observed after 72 hours... |
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... |
We have previously reported several methods of in vitro immunization using different conditioned media, and the highest antibody titer was observed when a mixture of three conditioned media[PHA-stimulated adherent splenocytes conditioned medium (ASM-P), ASM-p-stimulated non-adherent splenocyte conditioned medium (NASM-A), ASM-P-stimulated thymocyte conditioned medium (TM-A)] was used. In this experiment, thymocytes and/or bone marrow cells was added instead of above conditioned media... |
Kawasaki disease is an acute multisystemic disease affecting infants and children with prominent vasculitic features. Although there has been considerable progress in understanding the pathogenesis of this disease, the inciting cause remains unclear. It has been noticed that there were many immunologic abnormalities during the acute stage of Kawasaki disease. In the pres-ent study, we studied serum interleukin-6(IL-6), C-reactive protein(CRP),... |
We had developed a method of in-vitro immunization to increase antibody titer using several cnditioned media which were developed from mouse splenocyts and thymocytes. Using fetal calf serum, the splenocytes of the mouse were divided into two types; adherent cells and non-adherent cells. We used PHA to stimulate the adherent cells to produce PHA-stimulated adherent cell conditioned medium (ACSM-P). Non-adherent... |
To investigate the effect of dietary fats on cellular immune response in the immunosuppressed rats, different compositions in the quality and quantity of dietary fats were fed to sublethally irradiated male rats.
