  • The purpose of this study is to investigate effects of White Ginseng-Ejung-tang water extract (EJ) on production of various cytokines such as interleukin (IL)-2, IL-5, IL-6, IL-10, IL-12p70, macrophage inflammatory protein (MIP)-2, vascular endothelial growth factor (VEGF), keratinocyte-derived chemokine(KC), tumor necrosis factor (TNF)-${\alpha}$, and granulocyte macrophage colony-stimulating factor (GM-CSF) in RAW 264.7 mouse macrophages stimulated by lipopolysaccharide (LPS). Levels of cytokines were measured by High-throughput multiplex bead array cytokine assay based on xMAP (multi-analyte profiling beads) technology. EJ significantly decreased levels of IL-2, IL-12p70, IL-5, MIP-2 for 24 h incubation at the concentrations of 25, 50, and 100 ${\mu}g/mL$ in LPS-induced RAW 264.7 (P < 0.05). EJ significantly decreased levels of IL-6 at the concentrations of 50 and 100 ${\mu}g/mL$ (P < 0.05). EJ significantly decreased levels of IL-10 and VEGF at the concentrations of 25 and 100 ${\mu}g/mL$ (P < 0.05). EJ significantly decreased levels of KC at the concentrations of 100 ${\mu}g/mL$ (P < 0.05). EJ did not show any significant effect on TNF-${\alpha}$ and GM-CSF production. These results suggest that EJ has anti-inflammtory property related with its inhibition of IL-2, IL-5, IL-6, IL-10, IL-12p70, MIP-2, VEGF, and KC production in LPS-induced macrophages.

  • Theaflavins (TF) and thearubigins (TR) are constituents of tea pigments which are polyphenols derived from Korean fermentation tea. After TF, TR and [(-) epigallocatechin-3-gallate](EGCG) have been applied to macrophage cell line (RAW264.7) nitric oxide (NO) synthesis and cytokines production were estimated. Cytokines production by enzyme linked immune-sorbent assay (ELISA) determined. NO production was increased by about 1.5-folds at the dose of $80\;{\mu}g/ml$ compared to control and lipopolysaccharide (LPS) stimulation when TF, TR and EGCG were applied to a RAW264.7 cell. Interleukin-6 (IL-6), Tumor necrosis factor ($TNF-{\alpha}$) and granulocyte-macrophage colony stimulating factor (GM-CSF) increased depended on concentrations of TF, TR and EGCG. The production of tumor necrosis $factor-{\alpha}$ increased highly in TR, TF and EGCG group with LPS. These results suggest that TF, TR and EGCG have immune-enhancement effect through the cytokine production. TF, TR and EGCG inhibited cancer cell viability, the anticancer effect of these polyphenols may explain the anti-tumor promotion action and antioxidant activity of these tea constituents.

  • Adipocytes are endocrine cells that release bioactive mediators called adipokines. In condition of obesity characterized by low-grade chronic inflammation, adipocytes release inflammatory adipokines, which is related to insulin resistance. Bojungchiseub-tang (BJCST) has been used in symptoms and signs of edema, dampness-phlegm, kidney failure, and so on in Korean medicine. BJCST is also expected to have anti-obesity activities. In the present study, we examined whether BJCST modulate the production of inflammatory adipokines and the activations of the mitogen-activated protein kinases (MAPK) signaling pathway related to induce adipocyte inflammation to elucidate the effects and its mechanism of BJCST on lowering the content of inflammatory adipokines in 3T3-L1 adipocytes. As a result, BJCST suppressed the production of proinflammatory cytokines, tumor necrosis factor (TNF) $-{\alpha}$, interleukin (IL) $-1{\beta}$, IL-6, interferon (IFN) -${\gamma}$, granulocyte-macrophage colony-stimulating factor (GM-CSF), monocyte chemoattractant protein-1 (MCP-1), and the production of other inflammatory mediators, prostaglandin $E_2(PGE_2)$ and nitric oxide(NO)viadownregulationofcyclooxygenase-2(COX-2)andinducible NO synthase (iNOS) gene expressions. In addition, BJCST decreased the phosphorylation of MAPK that promotes the production of inflammatory adipokines in 3T3-L1 mature adipocytes. In conclusion, BJCST could regulate the production of inflammatory adipokines and MAPK signaling pathway related to induction of adipose inflammation.

  • Aspergillus niger has been used as a host to express many heterologous proteins. It has been known that the presence of an- abundant protease is a limiting factor to express a heterologous protein. The protease deficient mutant of A. niger was obtained using UV-irradiation. A total of $1{\times}10^5$ spores were irradiated with $10{\sim}20%$ survival dose of UV, 600 $J/m^2$ at 280 nm, and the resulting spores were screened on the casein-gelatin plates. Ten putative protease deficient mutants showing the reduced halo area around colonies were further analyzed to differentiate the protease deficient mutant from other mutant types. Among ten putative mutants, seven mutants showed significant growth defect on nutrient rich medium and two mutants appeared to be the secretory mutants, which resulted in the impaired secretion of extracellular proteins including proteases. A mutant $pro^--20$ showed reduced halo zone without any notable changes in growth rate. In addition, the starchdegrading and glucose oxidase activities in the culture filtrate of $pro^--20$ mutant showed the similar range as that of the parental strain, which suggested that the $pro^--20$ mutant ought to be the protease deficient mutant rather than a secretory mutant. The reduced proteolytic activity of the $pro^--20$ was demonstrated using SDS-fibrin zymography gel. The reduced extracellular proteolysis was quantified by casein degradation assay and, comparing with the parental strain, less than 30% residual extracellular protease activity was detected in the culture filtrate of the $pro^--20$ mutant. The bio-activity of an exogenously supplemented hGM-CSF(human Granulocyte-Macrophage Colony Stimulating Factor) in the culture filtrate of $pro^--20$ mutant was detected until eight times more diluted preparations than that of the parental strain.

  • Objective: Pegfilgrastim is recently introduced that is long acting G-CSF for prophylaxis of febrile neutropenia. Treatment of non-Hodgikin's lymphoma (NHL) with R-CHOP is classified with relative high risk of febrile neutropenia. The study evaluated the prophylactic effect of pegfilgrastim to reduce the incidence of febrile neutropenia associated with R-CHOP of patient in NHL. And the risk factors associated with the incidence of FN and related events were evaluated. Methods: This retrospective study reviews the Electronic Medical Record of 68 NHL patients who received R-CHOP chemotherapy in single center between September 2013 and August 2014. These patients were classified who receive prophylaxis pegfilgrastim or no prophylaxis. Results: Sixty eight patients received R-CHOP with NHL. In 144 cycles of patients receiving pegfilgrastim, compared with no prophylaxis 178 cycles, had a lower incidence of febrile neutropenia (5.5% vs. 23.6%, p = 0.001), grade 3 or grade 4 neutropenia (14.4% vs. 89.8%, p < 0.001) and neutropenia related events (p < 0.05). The risk of febrile neutropenia after prophylaxis was significantly associated with age ${\geq}65$ (OR: 5.87, 95% CI 1.07-32.27, p = 0.042), $IPI{\geq}3$ (OR: 7.2, 95% CI 1.31-39.6, p = 0.023), S.alb < 3.5 g/dL (OR: 31.01, 95% CI 6.32-152.17, p < 0.0001). In multiple logistic regression analysis, lower baseline serum albumin (OR: 21.1, 95% CI 3.8-116.98, p = 0.001) was significantly associated with occurrence of febrile neutropenia. Conclusion: The study recommends prophylactic pegfilgrastim through risk assessment of febrile neutropenia in patients with non-Hodgikin's lymphoma receiving R-CHOP.

  • The expression profiles of inflammatory cytokines viz. interleukins (IL)-6, IL-8, IL-12, granulocyte macrophage-colony stimulating factor, interferon-${\gamma}$ and tumor necrosis factor-${\alpha}$ in response to subclinical mastitis in indigenous cattle breed Kankrej (n = 6), Gir (Bos indicus) (n = 12) and crossbred (Bos taurus${\times}$Bos indicus) (n = 7) were investigated using quantitative real time PCR. Significant correlation (p < 0.05) was observed between total bacterial load and somatic cell count (SCC) in all three breeds of cattle. All the cytokines were observed to be up-regulated compared to cows with healthy quarters, however, level of their expression varied among three breeds of cattle. In Kankrej most cytokines were found to be transcribed to higher levels than in other two breeds; the milk had higher load of bacteria but not so high SCC, implying that Kankrej has a higher inherent resistance against mastitis. The results of present study indicated that mammary glands of crossbred cattle are more sensitive to bacterial infection than indigenous breed of cattle as they elicit immune response at lower bacterial load and result into higher SCC. Research on identification of factors responsible for differentially expressed cytokines profiles and use of cytokines as immunomodulatory tools can pave way for formulating control strategies against bovine mastitis.

  • Background : Production of cytokines by bronchial epithelial cells may contribute to the local accumulation of inflammatory cells in patients with bronchial asthma. In many recent studies, molecular biological methods have been used to investigate the role of cytokines in pathogenesis and new therapeutic targets of asthma. Objective : We aimed to identify the dose-dependent inhibitory effects of Socheongryong-tang and Socheongryong-tang plus Sasam (Adenophorae Radix) on the mRNA expressions of Interleukin (IL)-6, IL-8 and granulocyte macrophage colony stimulating factor (GM-CSF) involved in the asthma model. Materials and Methods : In this study, BEAS-2B cell lines, human epithelial cells, were used. These cells were stimulated by tumor necrosis factor $(TNF)-{\alpha},{\;}IL-1{\beta}$ and histamine for artificial inflammatory expression. ${\beta}-actin$ messenger RNA (mRNA) was used for the internal standard. After each 24 hours of the Socheongryong-tang (小靑龍湯) and Socheongryong-tang plus Sasam (小靑 龍湯加沙蔘) treatment, total cellular RNAs were collected by applying RNAzol directly to the living cells. Then the transcriptional activities of IL-6, IL-8 and GM-CSF were measured by RT-PCR with electrophoresis. Results : In the Socheongryong-tang (小靑龍湯) study, the mRNA expressions of IL-6, IL-8 and GM-CSF were significantly inhibited compared to that of the control group (p<0.05). In the Socheongryong-tang plus Sasam (小靑龍湯加沙蔘) study, the mRNA expressions of IL-6, IL-8 and GM-CSF were significantly inhibited compared to that of the control group (p<0.05). Conclusions : This study shows that Socheongryong-tang (小靑龍湯) and Socheongryong-tang plus Sasam (小靑龍湯加沙蔘) have dose-dependent inhibitory effects on the mRNA expressions of IL-6, IL-8 and GM-CSF in human epithelial cells, so these herbal medicines may inhibit the inflammatory process of asthma. Advanced studies are required to investigate the mechanisms of inhibition by herbal medicine in the asthma model.

  • Objective : Radiodermatitis is a common sequelae in 95% of patients receiving radiation therapy, which is important to be well managed as it can affect the patient's quality of life as well as the cancer treatment schedule. The aim of this study is to review and summarize the interventions available for the treatment of acute radiodermatitis, including traditional Korean medicine, and to propose treatment algorithms for clinicians. Methods : To collect studies about managements for radiodermatitis, domestic and foreign database were used such as Korean journal of traditional knowledge portal (KTKP), Korean studies information service system (KISS), national discovery or science leaders (NDSL), and oriental medicine advance searching integrated system (OASIS), Pubmed, Google scholar and Scopus. Results : Thirty-two studies were selected. There were nine studies on usual care and dressing, eleven studies on chemical agents, two studies on biological preparations, and ten studies on herbal medicines. Conclusion : Hygienic options and dressings have proved to be useful in the management of radiodermatitis. Chemical agents such as corticosteroid, statin, and topical antibiotic agent have proved to alleviate symptoms and severity, regenerate damaged skin, and prevent secondary infection. In biological preparations, EGF (epidermal growth factor) and GM-CSF (granulocyte-macrophage colony-stimulating factor) could be used to protect skin and prevent radiodermatitis. For herbal medicines, Calendula, catechin, β-sitosterol, and Jaungo (紫雲膏) may be effective for symptoms including pain, itching, and burning sensation induced by radiation therapy. Because of some research with conflicting results, further studies are needed to propose an algorithm for more optimal treatments.

  • Background: A combination of rituximab to cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) is one of the most effective front-line therapies to treat B-cell non-Hodgkin's lymphoma (NHL). The aim of this trial was to evaluate overall survival (OS), progression free survival (PFS) and toxicity of R-CHOP-14 compared to R-CHOP-21 in untreated stage III and IV B-cell NHL patients with Iranian ethnicity. Materials and Methods: In phase III trial, patients with previously untreated stage III and IV indolent and aggressive B-cell NHL were randomly assigned by using a minimization method to receive six to eight cycles of either R-CHOP-21 (administered every 21 days) or R-CHOP-14 (administered every 14 days with granulocyte colony-stimulating factor). Results: A total of 143 patients were randomly enrolled in our study (66 patients in R-CHOP-14 group and 77 patients in R-CHOP-21), between 2011 and 2014. The mean follow-up was 45 months at the time of treatment analysis. The 2-year and 5-year PFS rates for the R-CHOP-14 group were 83.6% vs 73.6% and for R-CHOP-21 group were 75% vs 54%. The 2-year and 5-year OS rates for R-CHOP-14 group were 98% vs 89% and for R-CHOP-21 group were 84.4% vs 67.5%. There was a significant correlation for PFS and OS in the two arms. There was no significant difference between adverse events with the two regimens. Conclusions: In our research improved survival was found with CHOP-14 as compared to CHOP-21. It is possible that drug metabolism in different races/ethnicities may be one important factor.

  • Korean red ginseng has shown therapeutic effects for a number of disease conditions. However, little is known about the anti-inflammatory effect of Korean red ginseng saponin fraction (RGSF) in vitro and in vivo. Therefore, in this study, we showed that RGSF containing 20(S)-protopanaxadiol type saponins inhibited nitric oxide production and attenuated the release of tumor necrotic factor (TNF)-${\alpha}$, interleukin (IL)-6, granulocyte monocyte colony stimulating factor (GMCSF), and macrophage chemo-attractant protein-1 in lipopolysaccharide (LPS) stimulated murine macrophage RAW264.7 cells. Moreover, RGSF down-regulated the mRNA expressions of inducible nitric oxide synthase, cyclooxyginase-2, IL-$1{\beta}$, TNF-${\alpha}$, GMCSF, and IL-6. Furthermore, RGSF reduced the level of TNF-${\alpha}$ in the serum and protected mice against LPS mediated endotoxic shock. In conclusion, these results indicated that ginsenosides from RGSF and their metabolites could be potential sources of therapeutic agents against inflammation.
