Tuberculous lymphadenitis is not uncommon in Korea. Therefore, an inexpensive, safe and rapid method is needed to diagnose the tuberculous lymphadenitis. Flne needle aspiration cytology Is a good method for this purpose, but has several limitations in the diagnosis of tuberculous lymphadenitis, especially when the presence of acid-fast bacilli is not proved. To evaluation the usefulness of the polymerase chain reaction with enzyme immunoassay technique in the detection of Mycobacterium tuberculosis (M. tuberculosis) In the cervical Iymph node asplrates, the authors performed fine needle aspiration cytology and M. tuberculosis PCR with enzyme immunoassay for mycobacterial DNA sequences from 15 cases of the fine needle aspirates. Cytomorphologically, the cases were categorized into three types: predominantly necrotic materials; typical epithelioid cell granulomas with or without slant cells and caseous necrosis; and non-tuberculous lesions, such as reactive lymphadenitis, abscess, metastatic carcinoma and malignant lymphoma. M. tuberculosis DNA was found in 8 of 15 cases by PCR with enzyme immunoassay. Negative findings on PCR were achieved in 7 cases, which revealed non-tuberculous tymphadenopathy. In conclusion, we suggest that M. tuberculosis PCR with enzyme immunoassay using the fine needle aspirates is a very useful tool for the diagnosis of tuberculous lymphadenitis.

This study was investigated the anti-allergic effect of SJSBT on DNCB induced atopic dermatitis in NC/Nga mice. We summerized as the follow. SJSBT significantly decreased the clinical manifestations of atopic dermatitis including itching, dryness, edema, hemorrhage, and lichenification in dose dependent manner. SJSBT markedly suppressed invasion and edema of leukocytes and mast cell in dorsal skin and ear tissue. SJSBT significantly reduced the number of CD11b+/Gr-1 cell compared with positive control, but it had no affect the number of CD3+ and CCR3+/CD3+ cell. SJSBT markedly suppressed the expression of cytokine and chemokine such as IL-6, $TNF-{\alpha}$, eotaxin and CCR3 compared with positive control group. SJSBT significantly decreased the invasion of CD4+ and CCR3+ cell in ear and dorsal skin tissue compared with positive control group by using immunohistochemical staining. Taken together, these findings suggested that SJSBT has an anti-allergic activity and this might be useful for the clinical application to treat allergic diseases such as atopic dermatitis.

Mubigangjang-Ju (MGJ) is a traditional wine, fermented extract of Cynanchum wilfordii, Angelicae gigantis and Epimedium koreanum etc. In the present study, we comparatively investigated the immune-enhancing effect of fermented extract (MGJ) and water extract (WE). Forced swimming test (FST) was performed as a model of activity test in mice and measured blood urea nitrogen (BUN), aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactic dehydrogenase (LDH), glucose (Glc) and total protein (TP) in the serum. Each extracts were orally administered into mice, 10 ㎖/kg, once per day for 7 days using a feeding atraumatic needle. After 3 days, on FST, the immobility time was decreased in the MGJ-fed group (133.7±18.6 s) in comparison with the saline-fed group (155.8±16.6 s). After 7 days, the immobility time was significantly decreased in the MGJ-fed group (105.3±12.7 s) in comparison with the saline-fed group (171.3±8.1 s). In addition, the content of AST was significantly decreased and the contents of BUN, ALT and LDH in the blood serum was also decreased. Whereas, the content of Glc tend to increase and TP level was not changed. However, WE had no effect on all experiments. The present results suggest that fermented extract was more effective than water extract and it may be useful for the immune-enhancing agent.

In the present study, the effects of different photoperiods on stress, immunity, and hematological parameters in ICR mice were evaluated. Fifty male ICR mice 7 weeks old (body weight, $27.3{\pm}2.5g$) were divided into five groups: DP-0 (0/24-h light/dark cycle), DP-6 (6/18-h light/dark cycle), DP-12 (12/12-h light/dark cycle), DP-18 (18/6-h light/dark cycle), and DP-24 (24/0-h light/dark cycle). During the experimental period, no significant differences in body weight or feed intake were observed between the groups. Hematological analysis revealed that white blood cell, red blood cell, and hemoglobin values for the DP-0 group were significantly different compared to those of the other groups. After 28 days, no significant difference in serum cortisol concentration was observed among the groups, but serum cortisol levels increased in a light exposure-dependent manner. Total serum immunoglobulin G (IgG) concentrations of the DP-0 and PD-6 groups were significantly increased compared to those of the other groups (p < 0.05), and serum total IgG levels decreased in a light exposure-dependent manner. Results of the present study indicated that various photoperiods affect hematological parameters and total serum IgG levels in ICR mice while having no significant effects on body weight, feed intake, or cortisol levels.

Background: Granulocyte colony stimulating factor (G-CSF) is known as a cytokine central to the hematopoiesis of blood cells and to modulate their cellular functions. Besides granulocytes and their precursors, monocytes/macrophages and endothelial cells are direct target cells of G-CSF action. G-CSF influences immune cells in an anti inflammatory way. Methods: To evaluate whether G-CSF has a potential for preventing or ameliorating diseases characterized by mucosal inflammation, we used a mouse model with trinitrobenzene sulfonic acid (TNBS)-induced inflammatory colitis. To the mice model G-CSF was administrated daily by intraperitoneal injection. Macroscopic evaluation and immunohistochemical analysis of colonic tissues were performed. Results: Re combinant human G-CSF significantly inhibited LPS-induced TNF-${\alpha}$ mRNA expression in THP-1 cells. As for in vivo relevance, G-CSF dramatically reduced the weight loss of mice, colonic damage, and mucosal ulceration that characterize TNBS colitis. Moreover, G-CSF suppressed the expression of tumor necrosis factor-${\alpha}$, interleukin-$1{\beta}$, and intercellular adhesion molecule-1 in TNBS colitis. Conclusion: Current results demonstrate that G-CSF may be an effective agent for the treatment of diseases characterized by mucosal inflammation.

This study was conducted to investigate the anti-inflammatory effects of Pruns mume, Schisandra chinensis, Chaenomeles sinensis-- Prunus mume mixtrue (PM) treatment on colitis induced in mice by dextran sodium sulfate (DSS) treatment. A total of 25 male BALB/c mice (average weight $20.7\;{\pm}\; 1.6 \;g$) were divided into 5 treatment groups and fed a commercial diet (A), PM administration (B), commercial diet + induced colitis by DSS (C), PM administration + induced colitis by DSS (D) and sulfasalazine + induced colitis by DSS (E). We found that PM treatment (D) and sulfasalazine (E) decreased the expression of $TNF-{\alpha}$ and COX-2 compared to the DSS-induced colitis group (C). The expression of IL-4, STAT6, $IFN-{\gamma}$, STAT1 was decreased in group D and group E compared to the colitis group (C), COX-2 and STAT1 were more decreased in group D. The serum IgE levels decreased in the PM treatment groups (C and D) compared to the non-PM treatment groups (A and B) although there was no significant difference between the PM treatment groups. It is notable that a therapeutic application of the PM extracts ameliorated DSS-induced colitis in mice.

In this study, the fiber-optic fluoro-immunosensor was designed to detect foodborne pathogens. The fabricated system is composed of the multimode optical fiber on which antibodies are immobilized. Then, a sandwich immunoassay is applied to the fabricated the fiber-optic fluoro-immunosensor. In the "sandwich" binding format, a primary or "capture" antibody is immobilized on the core surface of the multimode optical fiber and a secondary or named as "tracer" antibody is added to the bulk solution. A tracer is labeled FITC (fluorescein isothiocyanate; ${\lambda}ex$=492 nm, ${\lambda}em$= 520 nm). Different concentrations of antigens are tested in different fibers. The detection limit of the fabricated system is 5.08×103 cfu/ml for Vibrio antigen and $0.1{\mu}g/ml$, $0.05{\mu}g/ml$ in non-labeled monolayer phosphate buffered saline (NMP), non-labeled monolayer carbonate bicarbonate buffer (NMC), respectively.
