  • We designed the experiments to elucidate the anti-inflammatory effect of low power laser stimulation on acupoint or non-acupoint using arthrogenic solution induced poly arthritis animal model. In order to achieve the experimental purpose, change in body weight paw edema, pathological changes in inflammed pint and the serum interlukin-6 level were measured after arthritis induction in acupoint later stimulated group, non acupoint laser stimulated group and non treated control animal. The results were summerized as follows: 1. The consistent increase in body weight was observed in the normal animal during whole experimental period, while the induction of arthritis significantly suppressed increase in body weight from the 15 day after arthritis induction. Especially, non treated animal group showed more suppressive effect on increase in body weight as compared to that of low power laser stimulated groups (P<0.05). 2. Low power laser stimulation on acupoint (Zusanli) significantly inhibited edema in the left side paw from the 12th day after arthritis induction as compared to that of non treated animals. This suppressive effect on paw edema was maintained until the end of experiment. 3. Laser treatment on acupoint dramatically suppressed the radiological change (i.e. new bone proliferation and soft tissue swelling) caused by arthritis as compared to that of non treated group animals. 4. Low power laser treatment reduced the increase in serum interlukin-6 caused by arthritis induction to levels observed in the normal animals. In conclusion, the results of the present study demonstrated that low power laser stimulation on acupoint has potent anti-inflammatory effect on arthritis. Thus it is recommended that low power laser be used for long term treatment of arthritis induced inflammation. However, further study is necessary to clarify the possible side effect of laser treatment depending upon intensity and duration of stimulation.

  • Objective: To investigate the effect of intraoperative glucose fluctuation and postoperative interlukin-6 (IL-6), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), C-reactive protein (CRP) levels on the short-term prognosis of patients with intracranial supratentorial neoplasms. Materials and Methods: Eighty-six patients undergoing intracranial excision were selected in The Second Hospital of Jilin University. According to the condition of glucose fluctuation, the patients were divided into group A (glucose fluctuation <2.2 mmol/L, n=57) and group B (glucose fluctuation ${\geq}2.2mmol/L$, n=29). Glucose was assessed by drawing 2 mL blood from internal jugular vein in two groups in the following time points, namely fasting blood glucose 1 d before operation ($T_0$), 5 min after anesthesia induction ($T_1$), intraoperative peak glucose ($T_2$), intraoperative lowest glucose ($T_3$), 5 min after closing the skull ($T_4$), immediately after returning to intensive care unit (ICU) ($T_5$) and 2 h after returning to ICU ($T_6$). 1 d before operation and 1, 3 and 6 d after operation, serum IL-6 and TNF-${\alpha}$ levels were detected with enzyme-linked immunosorbent assay (ELISA), and CRP level with immunoturbidimetry. Additionally, postoperative adverse reactions were monitored. Results: There was no statistical significance between two groups regarding the operation time, anesthesia time, amount of intraoperative bleeding and blood transfusion (P>0.05). The glucose levels in both groups at $T_1{\sim}T_6$ went up conspicuously compared with that at $T_0$ (P<0.01), and those in group B at $T_2$, $T_4$, $T_5$ and $T_6$ were significantly higher than in group A (P<0.01). Serum IL-6, TNF-${\alpha}$ and CRP levels in both groups 1, 3 and 6 d after operation increased markedly compared with 1 d before operation (P<0.01), but the increased range in group A was notably lower than in group B (P<0.05 or P<0.01). Postoperative incidences of hypoglycemia, hyperglycemia and myocardial ischemia in group A were significantly lower than in group B (P<0.05), and respiratory support time obviously shorter than in group B (P<0.01). Conclusions: The glucose fluctuation of patients undergoing intracranial excision is related to postoperative IL-6, TNF-${\alpha}$ and CRP levels and those with small range of glucose fluctuation have better prognosis.

  • Banhabaikchulcheunma-tang (BBCT), a prescription composed of thirteen herbal mixtures, has been widely used in the treatment of brain disorders in Oriental Medicine. However, the mechanisms by which the formula affects on the production of pro-inflammatory cytokines in cerebral infarction (CI) patients remain unknown yet. The levels of secretory protein of pro-inflammatory cytokines, including tumor necrosis factor (TNF)-a, interlukin (IL)-1b, and IL-6, were significantly increased in lipopolysaccharide (LPS)-stimulated THP-1 differentiated macrophage-like (THP-1/M) cells and Peripheral blood mononuclear cells (PBMCs) from CI patients. However, pretreatment with BBCT significantly inhibited the secretion of pro-inflammatory cytokines, including TNF-a, IL-1b, and IL-6, in THP-1/M cells and PBMCs from CI patients with stimulus. Thus, these data indicate that BBCT may be beneficial in the cessation of inflammatory processes of cerebral infarction through suppression on the production of pro-inflammatory cytokines.

  • In this study, we established a radiodermatitis animal model and investigated the change in immune cell proportions in the secondary lymphoid organs. The cells responsible for the increased transforming growth factor-${\beta}1$ (TGF-${\beta}1$) and interleukin-10 (IL-10) production in the lesions following irradiation were also investigated. The radiodermatitis model was constructed by locally exposing the posterior dorsal region of hairless-1 (HR-1) mice to 10 Gy electron (E)-ray/day for six consecutive days. The change in immune cell proportions was analyzed by FACS. Immunohistochemistry was carried out to detect the expression of cytokines and cell-specific markers in the skin. The proportions of antigen-presenting cells, T cells, and B cells in the lymph nodes and spleen were affected by E-irradiation. After irradiation, TGF-${\beta}1$ and IL-17 were co-localized in the papillary region of the dermis with keratin-14 (K-14)-positive cells rather than with regulatory T cells (Treg). IL-10 was not co-stained with Treg, T helper 17 (Th17) cells, dendritic cells, or macrophages. Our data indicate that TGF-${\beta}1$ is over-expressed mainly by proliferated keratinocytes in the lesions of a radiodermatitis animal model.

  • To evaluate the anticolitic effect of red ginseng (RG, the steamed root of Panax ginseng CA. Meyer, Araliaceae), RG and its representative constituents, ginsenosides Rg3 and Rh2, were orally administered to dextran sulfate sodium (DSS)-induced colitic mice and inflammatory markers investigated. RG and its constituents, ginsenosides Rg3 and Rh2, inhibited colon shortening and myeloperoxidase activity induced by DSS. The ginsenosides Rg3 and Rh2 inhibited mRNA expression of interleukin (IL)-$1{\beta}$ as well as protein levels of IL-$1{\beta}$ and IL-6. These ginsenosides also inhibited the activation of a transcription nuclear factor (NF)-${\kappa}B$. Ginsenoside Rh2 was a more potent inhibitor than ginsenoside Rg3. The anticolitic effects of these ginsenosides were comparable with sulfasalazine.

  • In the present study, baicalin, baicalein, and wogonin, a major flavone isolated from Scutellaria Radix were examined for their effects on PMA-induced Interlukin-6 (IL-6), $interferon-\gamma(IFN-\gamma)$, tumor necrosis factor $(TNF)-\alpha$, IL-4, IL-10, and IL-13 productions in the PMA-stimulated $CD4^+$ Jurkat T cells. These three compounds inhibited PMA-induced Th1 cytokine $(IL-6,\;IFN-\gamma,\;TNF-\alpha)$ and Th2 cytokine (IL-4 and IL-13) productions in a concentration-dependent manner. But wogonin, but not baicalin baicalein, increased PMA-induced IL-10 production. These results suggest that baicalin, baicalein, and wogonin, a major flavone modulate Th1 and Th2 cytokine productions in $CD4^+$ Jurkat T cells and these properties may contribute to the anti-atopic dermatitis activity of Scutellaria Radix.

  • Halogenated organic compounds, such as 1-bromobutane (1-BB), have been used as cleaning agents, agents for chemical syntheses or extraction solvents in workplace. In the present study, immunotoxic effects of 1-BB and its conjugation with glutathione (GSH) were investigated in female BALB/c mice. Animals were treated orally with 1-BB at 375, 750 and 1500 mg/kg in corn oil once for dose response or treated orally with 1-BB at 1500 mg/kg for 6, 12, 24 and 48 hr for time course. S-Butyl GSH was identified in spleen by liquid chromatography-electrospray ionization tandem mass spectrometry. Splenic GSH levels were significantly reduced by single treatment with 1-BB. S-Butyl GSH conjugates were detected in spleen from 6 hr after treatment. Oral 1-BB significantly suppressed the antibody response to a T-dependent antigen and the production of splenic intracellular interlukin-2 in response to Con A. Our present results suggest that 1-BB could cause immunotoxicity as well as reduction of splenic GSH content, due to the formation of GSH conjugates in mice. The present results would be useful to understand molecular toxic mechanism of low molecular weight haloalkanes and to develop biological markers for exposure to haloalkanes.

  • Obesity is considered a mild inflammatory state, and the secretion of inflammation-related cytokines rises as adipose tissue expands. Inflammatory cytokines, including tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interlukin 6 (IL-6) and monocyte-chemoattractant protein 1 (MCP-1), are modulated by adipose tissue and known to play an important role in insulin resistance which is the common characteristics of obesity related disorders. In this study we analyzed the effects of Sasa borealis leaves extract on inflammatory cytokines and insulin resistance in diet induced obese C57/BL6J mice. The obese state was induced by a high fat diet for 20 weeks and then the mice were divided into two groups; obese control group (OBC, n = 7) and experimental group (OB-SBE, n = 7). The OBC group was fed a high fat diet and the OB-SBE group was fed a high fat diet containing 5% Sasa borealis leaves extract (SBE) for 12 weeks. We also used mice fed a standard diet as a normal control (NC, n = 7). The body weight and adipose tissue weight in the OB group were significantly higher than those in the NC group. The effects of the high fat diet were reduced by SBE treatments, and the body weight and adipose tissue deposition in the OB-SBE group were significantly decreased compared to the OBC group. The OBC group showed higher serum glucose and insulin levels which resulted in a significant increase of incremental area under the curve (IAUC) and HOMA-IR than the NC group. Also, serum leptin, TNF-${\alpha}$, and IL-6 levels were significantly higher in the OBC group than in the NC group. In contrast, the OB-SBE group showed a reversal in the metabolic defects, including a decrease in glucose, insulin, IAUC, HOMA-IR, TNF-${\alpha}$, IL-6 and leptin levels. These results suggest that BSE can suppress increased weight gain and/or fat deposition induced by a high fat diet and theses effects are accompanied by modulation of the inflammatory cytokines, TNF-${\alpha}$ and IL-6 secretion resulting in improved insulin resistance.

  • Adlay bran is a waste product previously thought to have no commercial value, Its methanolic extract was fractionated using n-hexane (ABM-Hex), ethyl acetate (ABM-EtOAc), 1-butanol (ABM-BuOH), and water (ABM-$H_2O$). The ABM-EtOAc fraction exhibited a strongest inhibition against growth of human lung cancer cell A549 and human colorectal carcinoma cells HT-29 and COLO 205. Inhibition of cell cycle progression at $G_0/G_1$ transition, increase of cells at the sub-$G_1$ phase, and DNA ladders were observed in cells treated with ABM-EtOAc. The ABM-BuOH fraction showed the strongest inhibition of proinflammatory cytokines tumor necrosis factor (TNF)-$\alpha$ and interlukin (IL)-$1{\beta}$ in stimulated RAW 264.7 macrophages. Further, ABM-EtOAc and ABM-BuOH inhibited cyclooxygenase (COX)-2 expression in A549 and HT-29 carcinoma cells, while COX-l expression was not affected. These results reveal that both ABM-EtOAc and ABM-BuOH may aid the prevention of cancers and the applications in cancer chemotherapy.

  • BACKGROUND: The aim of this study is to investigate the effects of Lycium chinense Miller fruit and its representative constituent betaine on reduction of immobility time and blood parameters in balb/c mice. METHODS AND RESULTS: We investigated the immobility time and the changes in aspects of blood biochemical parameters by the administration of L. chinense Miller fruit and its representative constituent betaine, after the forced swimming test. The immobility time was significantly reduced about 41.3% and 53.6%, respectively, in the animal of L. chinense Miller fruit and its representative constituent betaine-administrated group for 7 days, in comparison with that of the control group. The level of blood urea nitrogen was significantly decreased in L. chinense Miller fruit and its representative constituent betaine-treated group compared with the control group (P < 0.05), respectively. In addition, the interlukin-2 levels of mice in L. chinense Miller fruit and betaine treated group was increased compared with the control group. CONCLUSION: These results indicate that L. chinense Miller fruit and betaine might be helpful in the immune function improvement, enhance physical stamina, and fatigue recovery.
