This study was performed to investigate the immunological side effects of chloramphenicol (CAP) on olive flounder, Paralichthys olivaceus. To investigate immunological effects on olive flounder, we determined the changes of chemiluminescence (CL) response of flounder kidney-derived leucocyte after the treatment of CAP in vivo and in vitro. The CL activity was significantly decreased in a dose-dependent manner during the treatment of CAP in vitro. Similarly, a dose-dependent reduction of CL response, although not significant, were observed during the treatment of CAP in vivo. The results suggest that CAP reduced the function of flounder phagocytosis in vivo and in vitro, indicating the immunosuppressive ability of CAP.

Immunosuppressive potential of 65 kDa buffalo placental protein (bPP65) on B-cell proliferation in vitro and antibody response in vivo was evaluated. B-cell proliferation was estimated by measuring incorporation of tritiated thymidine in buffalo lymphocytes while primary antibody responses against phytohaemagglutinin (PHA) or keyhole limpet haemocyanin (KLH) were evaluated in mice. bPP65 suppressed proliferation of lipopolysaccharide (a B-cell specific mitogen)-stimulated buffalo lymphocytes in vitro indicating suppression of B-cells. This suppression was dose dependent over the protein concentration range $25-100 {\mu}g/ml$. Primary antibody responses in mice against PHA and KLH in presence of bPP65 were lower as compared to in its absence but these were not statistically significant. Amino acid composition data of bPP65 and BSA suggested that bPP65 is different from BSA.

The herbal combination allergina has been used for the treatment of inflammatory diseases in South Korea. In this study. we investigated the immunosuppressive activities of allergina in more detail. Acute graft-versus-host disease (GVHD) is a major cause of morbidity and mortality in patients undergoing allogeneic bone marrow transplantation. (omitted)

The oriental herbal combination allergina has been shown to inhibit allergic inflammation. In the present study, we demonstrate that the oral administration of allergina markedly inhibits the progression of inflammatory diseases, such as graft-versus-host diseases (in the allogeneic bone marrow transplantation and the parent-into-F1 transplantation models), collagen-induced arthritis and sheep red blood cell-induced delayed type hypersensitivity. The immunosuppressive activity of allergina in vivo appears to be associated, at least in part, with the inhibition of tumor necrosis factor-a production. In conclusion, our results suggest that allergina could be useful as a immunosuppressive agent for the treatment of macrophage-related inflammatory disease.

The NFAT family of transcription factors plays pivotal roles in the development and function of the immune system. Their activation process is tightly regulated by calcium-dependent phosphatase calcineurin and has been a target of the immunosuppressive drugs cyclosporin A and FK-506. Although the clinical use of these drugs has dramatically increased the success of organ transplantation, their therapeutic use is limited by severe side effects. Recent studies for the calcineurin/NFAT signaling pathway have identified a number of cellular proteins that inhibit calcineurin function. Specific peptide sequences that interfere with the interaction between calcineurin and NFAT have also been characterized. Moreover, diverse approaches to identify small organic molecules that modulate NFAT function have been performed. This review focuses on the recent advances in our understanding of the inhibitory modulation of NFAT function, which may open up the additional avenues for immunosuppressive therapy.

Pyoderma gangrenosum is a rare inflammatory reactive dermatosis marked by painful cutaneous ulcers. Diagnosis of pyoderma gangrenosum is usually made based on past medical history and after the exclusion of other possible diseases based on the clinical manifestations of the lesion. Diseases that show rapid progression to necrosis and that should not be misdiagnosed as pyoderma gangrenosum include malignant neoplasms and necrotizing fasciitis. Immunosuppressive agents such as steroids and cyclosporine are considered first-line therapy. Surgical removal of the necrotic tissues is contraindicated, as it may further induce immune reaction and promote ulcer to enlarge. Here, we present a case to encourage plastic surgeons to consider pyodermagangrenosum in the differential diagnosis of idiopathic ulcers. Satisfactory outcomes for patients with pyodermagangrenosum may be expected when using steroids and immunosuppressive agents during the early stage of the disease.

Statin is commonly used for lowering cholesterols and can be myotoxic to cause drug-induced necrotizing myopathy. Statin-induced myopathy ranges from asymptomatic hyperCKemia to lethal rhabdomyolysis but is usually reversed by withdrawal of causative drugs. The patient in this study presented with statin-induced necrotizing myopathy, which was finally improved with immunosuppressive therapy, but not just with drug withdrawal. Since statin can induce myopathy through autoimmune processes, we should consider using immunomodulating agents in cases with statin-induced myopathy, which is refractory to drug withdrawal.

Strongyloides stercoralis is an intestinal nematode that occurs sporadically in temperate areas like Korea. People who are in the immunosuppressed state, over the age of 65 or under the corticosteroid therapy are at risk for developing Strongyloides hyperinfection syndrome. Acute respiratory distress syndrome (ARDS) with alveolar hemorrhage is a rare presentation of Strongyloides hyperinfection. A 78-year-old man had been irregularly injected corticosteroid on his knees, but did not have any immunosuppressive disease. He was initially diagnosed with ARDS and septic shock. Bronchoalveolar lavage (BAL) fluid was bloody and its cytology revealed helminthic larvae identified as S. stercoralis. Results of Cytomegalovirus polymerase chain reaction (PCR), Pneumocystis jirovecii PCR, and Aspergillus antigen testing of the BAL fluid were positive. The clinical progress quickly deteriorated with multiple organ failure, shock and arrhythmia, so he finally died. This is a rare case of ARDS in an older patient without any known immunosuppressive conditions, with alveolar hemorrhage and S. stercoralis being found via BAL.

The objective of the study is to estimate the potential of gintonin, as an immune enhancing agent through natural killer cell (NK cell) activity in cyclophosphamide (CY)-induced immunosuppressive animals. Accumulated results reveals that, gintonin attenuated CY-induced immunosuppression and it might modulate NK cell activity to boost the immunity.
