1. Avaliação do efeito de extratos de plantas da flora catarinense sobre a proliferação de células mononucleares humanas / Evaluation of the effect of plant extracts from flora of Santa Catarina on human mononuclear cell proliferation
Muitas são as plantas utilizadas na medicina popular, a maioria delas desconhecidas quanto ao efeito sobre o sistema imune. A identificação e caracterização de compostos naturais obtidos a partir de plantas e que apresentam atividade imunomodulatória vem sendo área de estudo em vasto desenvolvimento. O teste de linfoproliferação é um dos métodos u

2. Longitudinal study of immune response in human Chagas' disease.
Immune response, clinical status, and reactivity to heart tissue were studied longitudinally for 1 year in 42 patients with Chagas' disease (South American trypanosomiasis). The patients were divided into two groups. Group 1 was composed of patients with chagasic infection with no evidence of heart disease. Group 2 patients had chagasic infection and cardiom

3. Expression of the C3d-binding protein (CR2) from Candida albicans during experimental candidiasis as measured by lymphoblastogenesis.
The complement C3d-binding protein (CR2) of Candida albicans has been purified by immunoaffinity chromatography, and its specificity has been characterized by immunoblotting with monoclonal antibodies to the C. albicans CR2 and the mammalian CR2. Recent studies with immunoelectron microscopy indicated that the CR2 was expressed during a systemic infection in

4. Delayed hypersensitivity to heart antigens in Chagas' disease as measured by in vitro lymphocyte stimulation.
Reactivity to Trypanosoma cruzi antigens and autoreactivity to heart antigens were evaluated in 27 patients with Chagasic cardiomyopathy (group I), 52 patients without evidence of cardiac dysfunction (group II), and 36 selected controls, either healthy patients or patients with other heart diseases (group III). The in vitro lymphoblastogenesis response to T.

5. Results of surgery on 6589 gastric cancer patients and immunochemosurgery as the best treatment of advanced gastric cancer.
Results of 6589 gastric cancer operations at the Department of Surgery, Seoul National University Hospital, from 1970 to 1990 were reported. About two thirds (76.6%) were advanced gastric cancer (stages III and IV). The 5-year survival rate of operated stage III gastric cancer was only 30.6%, with frequent recurrence. Conversely, cell-mediated immunities of

6. Opposite Effects of BCG on Spleen and Lymph Node Cells: Lymphocyte Proliferation and Immunoglobulin Synthesis
C57BL/6 mice were immunized intravenously (i.v.), intraperitoneally (i.p.), or subcutaneously with one dose of Bacillus Calmette-Guérin (BCG). At various time intervals after injection, the lymphocyte response, as measured by thymidine incorporation into DNA, and the number of immunoglobulin-secreting cells were determined in vitro before and after mitogeni
