The potential ability of ginger bioactive compounds in increasing the ratio of T-cell surface molecules of CD3+CD4+:CD3+CD8+ was investigated using dual tagging FITC and PE of monoclonal antibody anti-human with its fluorescence measured by flow cytometer. Oleoresin was extracted using sinkhole distillation technique. Its components namely, gingerol in fraction-1, shogaol in fraction 2 and zingeron in fraction-3 were separated by column vacuum chromatography method. The doses of oleoresin, gingerol, shogaol, and zingeron tested were 50, 100,150, 200, and 250 μg/ml. Lymphocytes (2x106 cell/ml) from human peripheral blood were isolated using ficoll density gradient technique, and cultured in the presence of the compounds in RPMI-1640 medium and phytohemaglutinin (PHA) mitogen for 96 h under normal conditions. Percentages of T-cell surface molecules (CD4+ and CD8+) were determined using dual-tagging FITC and PE fluorescents labeled on monoclonal antibody anti human. The fluorescence-labeled bands on the T-cell surface molecules were counted using flow cytometer. The experiment revealed that oleoresin and its three fractions increased the percentage of CD3+CD4+. The compound in fraction 3 of oleoresin at 200 μg/ml increased by the highest percentage of CD3+CD4+ of 9%, but slightly decreased the percentage of CD3+CD8+. These ginger bioactive compounds increased the ratio of CD3+CD4:CD3+CD8+ T-cells with the highest increment of 30% from effects of 200 μg/ml fraction 3 of oleoresin. This in vitro finding revealed that ginger bioactive compounds potentially increased cellular and humoral immune response. Further clinical studies are needed to confirm the benefits of these ginger bioactive compounds as a potential functional food for testing on HIV infected patients.

Objectives: Deep seawater (DSW) utilization technology has been developed for the fields of medicine and health, among others. To clarify the health effects of DSW as compared with surface seawater (SSW) or tap water (TW), we investigated the changes of immune cell distribution of the peripheral blood, or subjective judgment scores, after hot water bathing. Methods: Ten healthy young men were immersed for 10 min in DSW, SSW and TW heated to 42°C. Blood samples were collected before bathing, immediately after bathing and 60 min after bathing. Total and differential numbers of leucocytes and lymphocyte subsets (CD3, CD4, CD8, CD19, CD16, and CD56) were examined using an automated hematology analyzer and a flow cytometer, respectively. The subjective judgment scores were obtained by an oral comprehension test. Results: Since the pre-bathing leukocyte count in the TW group was significantly different from those in the DSW and SSW groups, we excluded the findings of TW bathing from consideration. In hot DSW bathing, CD8-lymphocytes increased significantly immediately after bathing (p<0.05), in contrast to hot SSW bathing, in which no significant changes were detected in the lymphocyte subsets. Additionally, there were no significant changes between repeated measurements in the subjective judgment scores, though the score of thermal sensation in SSW bathing showed a significantly higher value immediately after bathing than before bathing (p<0.01). Conclusions: Our findings suggest that increased CD8-lymphocytes in hot DSW bathing may improve human immune function as well as hot springs do, as compared with SSW bathing. Although hot DSW bathing may have the ability to change human immune cell distribution, well-designed studies are needed to clarify the health effects including not only DSW and SSW but also TW.

Recently, chimeric antigen receptors T cells (CAR T) have made a breakthrough in the treatment of lymphoma and leukemia, open a new path for the tumor cellular immunetherapy. It is the key for CAR T to take the gene which can identify the CD19 antigen of lymphoblastic leukemia into lymphocytes, enable it to kill leukemia cells with specific cell-surface loci. The same principle also applies to other aspects, if we find specific target genes of lymphocytes. Recent studies have found that high mobility group protein N2 (high mobility group chromosal protein N2, HMGN2) is the excellent target of tumor-associated antigen in lymphocytes, is the antitumor effector molecule of CD8(+) T cells, which has the ability of trends and specific identify/binding in myeloid leukemia, breast cancer, cervical cancer and other tumor cells. HMGN2 is expected to be used for the preparation of specific identification of tumor lymphocytes and to treat more leukemia and tumors. This article focuses on the strucure and function of HMGN and the chemotaxis and antitumor effect of HMGN2 in leukemia and tumors.

Graft-versus-host disease (GVHD) is a life threatening complication that may occur following allogenic bone marrow transplantation (BMT) in the patients with aplastic anemia, leukemia or genetic immunodeficiency. It has been known that GVHD occurs approximately 70% of recipients of BMT in western countries but no definite incidence has been reported in Korea. In our St. Mary's Hospital, GVHD occurs in about 30% of BMT recipients. Histopathologically the acute phase skin shows diffuse lymphocytic infiltrates in the upper dermis with extensive exocytosis. Scattered throughout the epidermis are many degenerated keratinocytes, which are often associated with one or more satellite lymphocytes (satellite cell necrosis). In the chronic phase, acanthosis, eosinophilic keratinocytes resembling colloid bodies and mononuclear cell infiltrates in the upper dermis are noted. We reviewed 5 cases of acute GVHD and 6 cases of chronic GVHD. All patients received allogenic BMT from Jan. 1, 1992 to July 1, 1993. Ten patients were male and one was female. The mean age was 34 (20-70). The pathologic diagnosis was 3 cases of CML, 2 of ALL, 2 of AML (FAB M2), 2 of aplastic anemia, 1 of CLL and 1 of AML (FAB M5). The interval from BMT to GVHD varied from 14 days to 4 years (median 220 days). The skin and GI tract were involved in all eleven cases. Ten cases were histologically proven by skin biopsies, and two cases by salivary gland and colonic biopsies, respectively. The histological findings of the skin, salivary gland and colonic biopsieds were described. Immunohistochemical stain of the skin was done using CD4, CD8, HLA DR and Leu 7 antibodies.

Vitiligo is an acquired, progressive depigmenting disorder of unknown etiology. In this study, to clarify pathogenesis of vitiligo, the marginal skin of actively spreading and stable vitiligo was examined using ICAM-1, HLA-DR, CD4 and CD8 monoclonal antibodies. In immunohistochemical study, ICAM-1 was expressed in four of five epidermis in active lesions, but not in stable lesion. Dermal ICAM-1 was also expressed in all active and stable lesions. HLA-DR was also expressed in all active epidermis in active lesions, but two of five epidermis in stable lesion. Dermal HLA-DR was also expressed in all active and stable lesion. CD4 lymphocytes were expressed more strongly in active lesion, but CD8 lymphocytes were not different in both lesions. There was no significant difference of degree of positivity with CD4 and CD8 in normal control specimens. In conclusion, we think that ICAM-1 and HLA-DR expression, cytokines released from keratinocytes, melanocytes or lymphocytes and infiltration of activated T-lymphocytes play an important role in disease activity.

OBJECTIVETo compare the in vivo immune reaction of transplanting porcine MSC-derived CLC with rabbit cardiomyocytes extracts induced differentiation or in vitro cultured porcine MSC.

METHODSAfter injecting the MSC-derived CLC or MSC to the original porcines, the number of CD4+, CD8+ T cells were determined by flow cytometry. The serum concentrations of IL-2, IL-4 were measured by ELISA, and the porcine spleen lymphocyte CTL cytotoxicity was determined by Cell Counting Kit-8 Assay.

RESULTSThe numbers of CD4+ and CD8+ T cells, the serum concentrations of IL-2, IL-4 and spleen lymphocyte CTL cytotoxicity were all similar in porcines received MSC-derived CLC induced by rabbit's CMs extract or MSC transplantation.

CONCLUSIONThe porcine MSC-derived CLC induced by rabbit's CMs extract did not induce extra immune reaction when injected back to the original porcine.

OBJECTIVETo determine the effect of early enteral nutrition (EN) on immune function of the patients after operation for severe abdominal trauma.

METHODSFourty patients who underwent operation for severe abdominal trauma were randomly divided into two groups, and received an early enteral nutrition (EN group, n=20) through jejunal nutritional tube from postoperative day 1, or parental nutrition (PN group, n=20) for 7 days. C3, IgA, IgM, IgG and CD3+, CD4+, CD8+, CD4+/CD8+ of the two groups patients were detected on the day before operation and the postoperative day 1 and 8. The infection complications were compared.

RESULTSAfter 7 days, the levels of C3+, IgA, IgG, CD3+, CD4+, CD8+, and CD4+/CD8+ in EN group increased significantly compared with those in PN group (P< 0.05). The incidence of infection was 10% in EN group, while 30% in PN group (P< 0.05).

CONCLUSIONEarly enteral nutrition can improve immune function and decrease postoperative infection after operation for severe abdominal trauma.
