  • Experimental studies were done to research the clinical effects of Juglandis Semen aqua-acupuncture and acupuncture(BL13, BL17, BL13ㆍ17 and free points) on the anti-allergic inflammation response. The following results have been obtained ; JSAA was increased in the lymphocyte proliferation in cultured murine thymocytes and splenocytes. The production of IL-1β was decreased in Juglandis Semen aqua-acupuncture and acupuncture(BL13, BL17 and BL13ㆍ17) group. The production of IL-4 was decreased in Juglandis Semen aqua-acupuncture and acupuncture(BL13, BL17 and BL13ㆍ17) group. The production of total IgG was decreased in Juglandis Semen aqua-acupuncture(BL13 and BL13ㆍ17) and acupuncture(BL13, BL17 and BL13ㆍ17) group. According to the above results, Semen aqua-acupuncture and acupuncture(BL13, BL17 and BL13ㆍ17) both enhances the specific immune response in T and B cells and depress the allergic inflammation reaction.

  • Codium fragile is an edible seaweed in Asian countries that has been used as a thrombolytic, anticoagulant, antioxidant, anti-inflammatory, and immune-stimulatory agent. Ginseng has also been known to maintain immune homeostasis and to regulate the immune system via enhancing resistance to diseases and microorganisms. In this study, anionic macromolecules extracted from C. fragile (CFAM) were orally administered with red ginseng extract (100 mg/kg body weight) to cyclophosphamide-induced immunosuppressed male BALB/c mice to investigate the immune-enhancing cooperative effect of Codium fragile and red ginseng. Our results showed that supplementing CFAM with red ginseng extract significantly increased spleen index, T- and B-cell proliferation, NK cell activity, and splenic lymphocyte immune-associated gene expression compared to those with red ginseng alone, even though a high concentration of CFAM with red ginseng decreased immune biomarkers. These results suggest that CFAM can be used as a co-stimulant to enhance health and immunity in immunosuppressed conditions.

  • In fascioliasis, T-helper 2 (Th2) responses predominate, while little is known regarding early immune phenomenon. We herein analyzed early immunophenotype changes of BALB/c, C57BL/6, and C3H/He mice experimentally infected with 5 Fasciola hepatica metacercariae. A remarkable expansion of $CD19^+$ B cells was observed as early as week 1 post-infection while $CD4^+/CD8^+$ T cells were down-regulated. Accumulation of $Mac1^+$ cells with time after infection correlated well with splenomegaly of all mice strains tested. The expression of tumor necrosis factor (TNF)-${\alpha}$ mRNA in splenocytes significantly decreased while that of IL-4 up-regulated. IL-$1{\beta}$ expression was down-modulated in BALB/c and C57BL/6 mice, but not in C3H/He. Serum levels of transforming growth factor (TGF)-${\beta}$ were considerably elevated in all mice during 3 weeks of infection period. These collective results suggest that experimental murine fascioliasis might derive immune suppression with elevated levels of TGF-${\beta}$ and IL-4 during the early stages of infection.

  • Cryptococcus neoformans infection usually occurs in patients with advanced human immunodeficiency virus (HIV) infection or with a CD4 T lymphocyte count of <100 cells/µL. Pulmonary and central nervous system infections are the most frequently encountered forms of cryptococcosis; however, colonic cryptococcosis is uncommon. We describe the case of a 41-year-old antiretroviral-naïve man with HIV infection diagnosed eight years prior and intermittent diarrhea for 4 months who presented to the emergency department with a 1-day history of low-grade fever and confusion. Brain magnetic resonance imaging and cerebrospinal fluid analysis revealed normal results; however, he was diagnosed with Pneumocystis jirovecii pneumonia based on chest computed tomography and bronchoalveolar lavage analysis. Trimethoprim-sulfamethoxazole administration was initiated followed by antiretroviral treatment. Although his condition gradually improved, he developed fever and abdominal discomfort, and the diarrhea worsened. Endoscopy revealed a small ulcer in the distal transverse colon. Histopathological examination of a colon tissue sample revealed cryptococcal infection. He improved substantially during liposomal amphotericin B and fluconazole treatment. We encountered a rare case of colonic cryptococcosis that caused chronic diarrhea in a patient with advanced HIV infection. Colonic cryptococcosis should be considered when patients with acquired immune deficiency syndrome present with gastrointestinal symptoms.

  • Numerous efforts have been made to isolate immunologically active component from Mori Cortex Radicis, since it has been used in the treatment of bronchial asthma, and immune dis order in human. Recently, we reported the purification of an anti-allergic component of the Mori Cortex Radicis. Among the fractions we prepared in the previous study, a fraction was active in the proliferation of murine lymphocytes. The active component (HHM 3-1) was elucidated as a polysaccharade with a small amount of lignin. When it was subjected to MALDI-MS by using 3-hydroxypicolinic acid as a matrix, the molecular weight of the component was estimated as 792688.2dalton. Total hexose and protein content of the component were estimated as 62.6% and 0.51%, respectively and it was composed mainly of glucose, galactose and mannose. The remaining part of the component was estimated as ligin because of the characteristic functional groups in IR and UV spectra. Concomitant treatment of HHM 3-1 with known mitogens synergistically increased the proliferation of B-cells and T-cells.

  • Granzyme A (GzmA) was identified as a cytotoxic T lymphocyte protease protein expressed in the nucleus. A number of nuclear proteins are well known as GzmA substrates, and GzmA is related with caspase-independent apoptosis. Histones H1, H2B, and H3 were identified as GzmA substrates through in vitro experiment with purified nucleosome. Here, we demonstrated that histone H3 was cleaved by GzmA in vivo during staurosporine-induced cell death. Moreover, histone H3 cleavage was blocked by the GzmA inhibitor nafamostat mesylate and by GzmA knockdown using siRNA. Taken together, we verified that histone H3 is a real substrate for GzmA in vivo in the Raji cells treated by staurosporin.

  • DW-116, [1-(5-fluoro-2-pyridyl)-6-fluoro-7-(4-methyl-1-piperazinyl)-1,4-dihydro-4-oxoquino-line-3-carboxylic acid hydrochloride}, is a new quinolone antibiotic with a broad antibacterial spectrum against G(+) and G(-) bacteria. DW-116 was evaluated for the immunomodulating activities, which is one of the efforts to investigate the mechanism of action related to the good in vivo antibacterial efficacy. The results of in vitro studies revealed there was no statistically significant increase in B and T lymphocyte proliferation. But the results of in vivo studies showed that the number of plaque forming cells (PFC), the amount of polyclonal antibodies and delayed-type hypersensitivity (DTH) were significantly increased after the repeat administration with 12 and 60 mg/kg of DW-116. Taken together, these results proposed that immunostimulting effect of DW-116 could be one of the action mechanisms for demonstrating in vivo antibacterial activities under these experimental conditions.

  • The immunostimulatory effects of quaternary ammonium compounds(QACs) were investigated in leucocytes of eel(Anguilla japonica) in vitro. Proliferation of peripheral blood lymphocytes(PBLs) was no significantly affected by QACs, regardless of mitogen(PHA, ConA and LPS) and the concentration of QACs added. QACs heightened the leucocytes function such as respiratory burst activity, phagocytosis and pinocytosis, resulting in significantly increased the bactericidal activity of macrophages. These results suggested that QAC might modulate the immune responses by activation of leucocytes function but not by increment of immunocompetent cell numbers.

  • Red ginseng(RG, steamed and dried root of Panax ginseng C. A. Meyer, family Araliaceae) and fermented red ginseng(FRG, fermented red ginseng by yeast and lactic acid bacteria) are known to show different pharmacological effects by changed composition of saponins through fermentation. We examined the effects of RG and FRG on $\beta$-hexosaminidase secretion, ICAM-1 expression, the mitogen-induced proliferation of lymphocyte from mice in ex vivo systems and HaCaT cell(keratinocyte) proliferation to compare the anti-allergic and anti-inflammatory effects between both groups. RG groups showed inhibition of $\beta$-hexosaminidase secretion and ICAM-1 expression at $1{\mu}g/ml$, $10{\mu}g/ml$ and the same effects were observed at all concentrations in FRG groups. In our study, RG increased LPS-induced B cell proliferation at $1{\mu}g/ml$ and ConA-induced B cell proliferation at $100\;{\mu}g/ml$ but FRG decreased LPS- and ConA-induced lymphocytes at $100\;{\mu}g/ml$. We showed that FRG increased the proliferation of HaCaT at 1, $10{\mu}g/ml$ but not by RG. These findings suggest that RG and FRG might have anti-inflammatory and anti-allergic effects, which can be needed to proper clinical concentration to applied to various allergic diseases and inflammation.

  • For evaluation of immune stimulation effect of lacquer tree extracts, lymphocytes were counted by labeling of FITC-conjugated monoclonal antibody in the pheripheral blood of pigs that fed with a fodder supplemented by lacquer tree extracts. Populations of MHC-II+, CD4+, and CD8+T lymphocytes were increased more than 2% level after 1 week feed supply of the lacquer tree extracts. The increase of those T cells reached at maximum level after 2 weeks in the tested group. B lympyocytes with surface IgM were increased 5% after 1 week feed supply of the lacquer tree extracts, and their numbers reached maximum after 2 weeks in the tested group. For the assessment of cytotoxicity of the lacquer tree extracts, morphological changes were examined on the epithelial cells of small intestine from pigs fed with a fodder supplemented by 0.1 % lacquer tree extracts for 6 weeks (the tested group). Thin-sectioned tissue of small intestine was fixed with glutaraldehyde, then coated with gold particles, and the specimen was examined under scanning electron microscope. The villi on the mucus membrane of jejunum and ileum from the tested pigswere enlarged on the tip and were linked each other.
