  • Diffuse infiltrative lymphocytosis syndrome is an autoimmune syndrome that is characterized by the oligoclonal expansion of CD8+ T-lymphocytes in response to human immunodeficiency virus (HIV) antigens. The clinical manifestations include bilateral enlargement of the parotid glands, lymphocytic interstitial pneumonitis, lymphocytic hepatitis, neurological involvement and systemic lymphadenopathies. In addition to a positive HIV test, the diagnostic histopathological findings are CD8+ T-lymphocytic infiltrations in the lymphnodes, liver, lung, muscle and the salivary or lacrimal glands without granulomatous or neoplastic involvement. We report a case of pulmonary involvement of diffuse infiltrative lymphocytosis syndrome that was associated with a human immunodeficiency virus infection.

  • We Previously reported that Polysaccharide Isolated from panax ginseng C. A. Meyer, stimulates murine splenocytes to proliferate and to be cytotoxic against a wide range of tumor cells in MHC non-restricted manner:) Therefore, we examined the cytokine mRNA expression induced by the ginseng polysaccharide in this paper. This study demonstrates that the ginseng polysaccharide stimulates Thl type cytosine expression such as IL-2 and IFNY, and macrophage type cytokine expression such as IL-lc and GM-CSF in a dose-dependent manner at different time: IL-2 mRNA was induced at 30 min, IL-la, GM-CSF mRNA at 3 hr, IFNY at 6 hr after the ginseng polysaccharide treatment. In contrast with these, Th2 type cytokine expression such as IL-4 and IL-5 was not induced. The generation of the ginseng polysaccharide-activated killer cells which was induced at the optimal doses of 50 pEyml was neutralized in the presence of anti-lL-2, anti-lFNy, anti-IL-l ${\alpha}$ antibodies, showing the importance of these cytokines produced by the ginseng polysaccharide. In flow cytometry analysis, the blastogenesis of IgM+ cells was induced on day 3 and the number of Thy 1.21 cells, CD4+ and CD8+ cells was increased on day 5. The ginseng polysaccharide also induced blastogenesis of T cells. In conclusion, the ginseng polysaccharide may have considerable antitumor immunotherapeutic modality by stimulating the cytokine production from Thl cells and macrophage and by proliferating lymphocytes.

  • Psoriasis is a common inflammatory disease of the skin marked by excessive scaling associated with inflammation, affecting 1-2% of the population. Although their etiologies remain unknown, the finding of CD4+ and CD8+ lymphocytes at sites of psoriasis has led many reports to hypothesize that psoriasis is a T lymphocyte-mediated disease directed against unknown autoantigens. The oriental medicine understands the cause of psoriasis as low humidity of skin tissues and functional deteriorations of the liver and lung. Gami-Yunbueum (GY) is a mixture of two previous prescription, which were used to the protection of liver and lung. We had prescribed the GY to the three psoriasis patients for 11 weeks and examined the effectiveness of the GY by PASI (Psoriasis Area and Severity Index) score. In our experiment, GY improved the symptoms of psoriasis in all cases. These results indicated that GY can apply to the treatment of psoriasis. Furthermore, the process for treatment of psoriasis is possible to provide humidity to skin and control the functions of liver and lung.

  • We here document discovery of a new and simple model of tumor seeding involving the mouse peritoneum. Irradiated tumor cells administered by i.p. injection provided effective vaccination against peritoneal carcinomatosis and distal metastasis with colorectal carcinomas. In flow cytometric analysis, CD4+ and CD8+ T lymphocytes, macrophages and myeloid-derived suppressor cells (MDSCs), which are easy to obtain in the peritoneal cavity, were revealed to have significant differences between immunized and non-immunized mice and these contributed to antitumor responses. We also observed that both serum and peritoneal lavage fluid harvested from immunized mice showed the presence of CT26-specific autoantibodies. In addition, increase in level of TGF-${\beta}1$ and IL-10 in serum but a decrease of TGF-${\beta}1$ in peritoneum was found. Taken together, these findings may provide a new vaccine strategy for the prevention of peritoneal and even systemic metastasis of carcinomas through induction of an autoimmune response in the peritoneum.

  • Rejection is one of the life-threatening complications after organ transplantation. An eight-month-old, intact male, mixed breed dog was presented with acute rejection after renal allograft. The heterotopic renal transplantation with bilateral nephrectomy was performed in the dog. The triple drug protocol for immunosuppression was applied for prevention of the acute rejection. Postoperative care was done according to the transplantation protocol of VMTH, Kangwon National University. The dog was euthanized when the serum creatinine concentration exceeded 5 mg/dL followed by tile signs of illness. The transplanted kidney was enlarged. The renal cortex lesions were characterized by necrosis of the renal tubules and the glomeruli. Interstitial lesions were characterized by hemorrhage and severe infiltration of lymphoid cells. Intrarenal arteries showed necrosis of the walls and infiltration of perivascular lymphoid cells. In immunohistochemical (IHC) findings, infiltration of the CD4 and the CD8 positive T lymphocytes was examined. In this case, acute rejection was shown by humoral and cellular immunity on the basis of histopathologic and IHC evaluation.

  • The purpose of this research was to investigate the effects of Kami Kwiryong Tang (KKT) on the immune cells in BALB/c mice. KKT (500mg/kg) was administerd p.o. once a day for 7 days. KKT decreased the proliferation of thymocytes, but did not affect the proliferation of splenocytes. KKT enhanced the subpopulation of Th (CD4+CD8- single positive cells) cells in splenic T-lymphocytes, but decreased the subpopulation of Th cells in thymocytes. KKT enhanced the production of ${\gamma}$-interferon and interleukin-2, but did not affect the production of interleukin-4 in mice serum. KKT did not affect the production of nitric oxide, but enhanced the phagocytic activity in peritoneal macrophages. These results suggest that KKT is a potent prescription on immune response via the production of cytokines from splenic Th1 cells and the increase of phagocytic activity in vivo.

  • Methanol extract prepared from the fruitbody of Phellinus linteus (EPL) showed anti-tumor and immune-stimulating activities. The invasion activity of Bl6-F10 melanoma cells through a reconstituted basement membrane to the collagen-coated lower surface of the filters was inhibited about 67% by EPL (100 $\mu\textrm{g}$/ml). Also, EPL inhibited the expression of the mRNA for MMP-2 and MMP-9. In vivo treatment of C57BL/6 mice (150 mg/kg) with EPL for 14 days, the pulmonary colonization was found to be inhibited about 75%. Using reverse transcriptionpolymerase chain reaction (RT-PCR) analysis, we found that cytokine IL-12 and INF-${\gamma}$ genes were induced by EPL. Furthermore, EPL stimulated the proliferation of CD4$\^$+/(33.5%) and CD8$\^$+/(17.7%) in mouse splenocytes.

  • Synthetic cannabinoids are one of most abused new psychoactive substances. The recreational use of abused drug has aroused serious concerns about the consequences of these drugs on infection. However, the effects of synthetic cannabinoid on resistance to tetanus toxin are not fully understood yet. In the present study, we aimed to determine if the administration of synthetic cannabinoids increase the susceptibility to tetanus toxin-induced motor behavioral deficit and functional changes in cerebellar neurons in mice. Furthermore, we measured T lymphocytes marker levels, such as CD8 and CD4 which against tetanus toxin. JWH-210 administration decreased expression levels of T cell activators including cluster of differentiation (CD) $3{\varepsilon}$, $CD3{\gamma}$, CD74p31, and CD74p41. In addition, we demonstrated that JWH-210 induced motor impairment and decrement of vesicle-associated membrane proteins 2 levels in the cerebellum of mice treated with tetanus toxin. Furthermore, cerebellar glutamatergic neuronal homeostasis was hampered by JWH-210 administration, as evidenced by increased glutamate concentration levels in the cerebellum. These results suggest that JWH-210 may increase the vulnerability to tetanus toxin via the regulation of immune function.

  • Background: Polysaccharides are the most important functional constituent in Astragalus membranaceus. The purpose of the present study was to evaluate the effect of polysaccharides isolated from the aboveground parts of A. membranaceus (AMA) and polysaccharides isolated from the roots of A. membranaceus (AMR) immune function by modulated cytotoxic T cell and Th1- and Th2-related cytokines kinetics. Methods and Results: Sprague-Dawley rats were randomly divided into exhaustive exercise case groups and non-exercise case, AMA and AMR samples were administered orally for 30 days (500 mg/kg/day and 10 mg/kg/day, respectively) and were compared to those rats in the groups fed commercial sports drink (SPD) and vehicle. Both exhaustive exercise groups and non-exercise groups had a lower ratio of $CD4^+$ and $CD8^+$ cells in the spleens of the rat fed AMA and AMR compared to those in the rats fed SPD and vehicle group. These results suggested that AMA and AMR promote an increase in the proportion of cytotoxic T cells. The IL-4-producing T lymphocytes decreased significantly in the AMR (10 mg/kg/day) group compared to SPD and vehicle, whereas the AMA group increased the IL-4 concentration more than the SPD and vehicle in exhaustive exercise group. However, the populations of IFN-${\gamma}$-producing T lymphocytes of AMR and AMA increased. AMA decreased the concentration of IFN-${\gamma}$ to inhibit the Th1 response and thereby increased the concentration of IL-4 to induce a Th2 response that was related to humoral immunity in the non-exercise group. Conclusions: These results showed that, in addition to Th1/Th2 regulation, AMR and AMA played an important immuno-modulatory role after exhaustive exercise-induced Th1/Th2 lymphocyte imbalance, which might be correlated with cytokine producing immunoregulatory cells.
