  • Objectives : This study was carried out to investigate the effects of Crataegi Fructus water extract(CFWE) on hair growth in an alopecia model of C57BL/6N mice and human dermal papilla cells(hDPCs). Methods : Six-week old mice were depilated and separated in 3 groups ; CON, MXD(2% Minoxidil), and CFWE. The treatments were applied twice a day for 18 days. The hair growth was determined photographically. The hair density, thickness and length were identified by Folliscope and the weights of body were measured. In dorsal skin tissue, the expression of hair growth-related protein was analyzed by Western blot. In hDPCs with/without $IFN-{\gamma}$, cell proliferation and the expression of hair growth-related genes were analyzed. Results : We observed that CFWE promoted hair growth compared to CON. CFWE improved the hair density, thickness and length compared to CON. CFWE increased the $Wnt/{\beta}$-catenin signaling in dorsal skin. In hDPCs, CFWE accelerated the cell proliferation and inhibited $IFN-{\gamma}$-induced hDPCs degeneration. CFWE increased the mRNA expression of ${\beta}$-catenin, Axin-2, BMP-4, FGF-7, FGF-10, and ALP compared to CON and $IFN-{\gamma}$ treated cells. Conclusions : These results suggest that CFWE has a hair regrowth activity via $Wnt/{\beta}$-catenin signaling and can be useful for the treatment of alopecia.

  • Purpose: The purpose of this study was to investigate the anti-inflammatory effects of the water extract of Omisodokeum (OMSDE) on peritoneal macrophages, Methods: To verify the anti-inflammatory mechanism of OMSDE, the activation of nuclear $factor-{\kappa}B$ $(NF-{\kappa}B)$ and the phosphorylation of MAPK were examined. Results: The extract of OMSDE suppressed the production of LPS-induced nitric oxide (NO), tumor necrosis factor $(TNF)-{\alpha}$, interleukin $(IL)-1{\beta}$, IL-6 and IL-12 in the macrophages. OMSDE inhibited the degradation of inhibitory ${\kappa}B-{\alpha}$ $(I{\kappa}B-{\alpha})$ and it suppressed the activation of extracellular signal-regulated kinase (ERK 1/2) but didn't inhibit c-Jun N-terminal kinase (JNK) and p38, indicating that OMSDE may inhibit the pro-inflammatory cytokine production process by inhibiting the activation of $NF-{\kappa}B$ and ERK 1/2. Furthermore, OMSDE inhibited the production of interferon $(IFN)-{\beta}$ but didn't inhibit of $IFN-{\alpha}$ in the LPS-stimulated macrophages through the down-regulation of interferon regulatory factor (IRF)-1 and IRF-7. The Oral administration of OMSDE inhibited LPS-induced endotoxin shock and the production of $TNF-{\alpha}$ in serum but didn't inhibit of $IL-1{\beta}$ and IL-6. Conclusion: These results suggest that OMSDE may be effective in the prevention and treatment of inflammatory diseases.

  • The present study aimed to show that pro-inflammatory cytokines [tumor necrosis factor (TNF)-${\alpha}$, interferon (IFN)-${\gamma}$, and interleukin (IL)-$1{\beta}$] synergistically induce the production of nitric oxide (NO) production in mouse mesangial cells, which play an important role in inflammatory glomerular injury. We also found that co-treatment with cytokines at low doses (TNF-${\alpha}$; 5 ng/ml, IFN-${\gamma}$; 5 ng/ml, and IL-$1{\beta}$; 1.25 U/ml) synergistically induced NO production, whereas treatment with each cytokine alone did not increase NO production at doses up to 100 ng/ml or 50 U/ml. Silymarin, a polyphenolic flavonoid isolated from milk thistle (Silybum marianum), attenuates cytokine mixture (TNF-${\alpha}$, IFN-${\gamma}$, and IL-$1{\beta}$)-induced NO production. Western blot and RT-PCR analyses showed that silymarin inhibits inducible nitric oxide synthase (iNOS) expression in a dose-dependent manner. Silymarin also inhibited extracellular signal-regulated protein kinase-1 and -2 (ERK1/2) phosphorylation. Collectively, we have demonstrated that silymarin inhibits NO production in mouse mesangial cells, and may act as a useful anti-inflammatory agent.

  • Lung fibrosis is a life-threatening disease caused by overt or insidious inflammatory responses. However, the mechanism of tissue injury-induced inflammation and subsequent fibrogenesis remains unclear. Recently, we and other groups reported that Th17 responses play a role in amplification of the inflammatory phase in a murine model induced by bleomycin (BLM). Osteopontin (OPN) is a cytokine and extracellular-matrix-associated signaling molecule. However, whether tissue injury causes inflammation and consequent fibrosis through OPN should be determined. In this study, we observed that BLM-induced lung inflammation and subsequent fibrosis was ameliorated in OPNdeficient mice. OPN was expressed ubiquitously in the lung parenchymal and bone-marrow-derived components and OPN from both components contributed to pathogenesis following BLM intratracheal instillation. Th17 differentiation of $CD4^+$ ${\alpha}{\beta}$ T cells and IL-17-producing ${\gamma}{\delta}$ T cells was significantly reduced in OPN-deficient mice compared to WT mice. In addition, Th1 differentiation of $CD4^+$ ${\alpha}{\beta}$ T cells and the percentage of IFN-$\gamma$-producing ${\gamma}{\delta}$ T cells increased. T helper cell differentiation in vitro revealed that OPN was preferentially upregulated in $CD4^+$ T cells under Th17 differentiation conditions. OPN expressed in both parenchymal and bone marrow cell components and contributed to BLM-induced lung inflammation and fibrosis by affecting the ratio of pathogenic IL-17/protective IFN-$\gamma$ T cells.

  • Background: Nitric oxide is a short-lived effector molecule derived from L-arginine by the nitric oxide synthase(NOS). Nitric oxide plays a role in a number of physiologic and pathophysiologic functions including host defense, edema formation, and regulation of smooth muscle tone. Some kinds of cells including macrophage are known to produce large quantities of nitric oxide in response to inflammatory stimuli such as interleukin-$1\beta$(IL-$1\beta$), tumor necrosis factor-$\alpha$(TNF-$\alpha$), interferon-$\gamma$(IFN-$\gamma$) and lipopolysaccharide(LPS). Reactive oxygen species are also known to be important in the pathogenesis of acute cell and tissue injury such as acute lung injury model Methods: Using the RA W264.7 cells, we have examined the ability of oxidant hydrogen peroxide($H_2O_2$) to stimulate nitric oxide production and inducible NOS mRNA expression. Also, we have examined the effects of NOS inhibitors and antioxidants on $H_2O_2$ induced nitric oxide production. Results: Stimulation of RAW264.7 cells with combinations of 100 ng/ml IL-$1\beta$, 100 ng/ml TNF-$\alpha$, and 100 U/ml IFN-$\gamma$ or 100 U/ml IFN-$\gamma$ and $1{\mu}g/ml$ LPS induced the synthesis of nitric oxide as measured by the oxidation products nitrite($NO_2^-$) and nitrate($NO_3^-$). Addition of $250 {\mu}M-2$ mM $H_2O_2$ to the cytokines significantly augmented the synthesis of $NO_2^-$ and $NO_3^-$(p<0.05). When cells were incubated with increasing concentrations of $H_2O_2$ in the presence of IL-$1\beta$, TNF-$\alpha$ and IFN-$\gamma$ at constant level, the synthesis of $NO_2^-$ and $NO_3^-$ was dose-dependently increased(p<0.05). $N^G$-nitro-L-arginine methyl ester(L-NAME), dose dependently, significantly inhibited the formation of $NO_2^-$ and $NO_3^-$ in cells stimulated with LPS, IFN-$\gamma$ and $H_2O_2$ at constant level(p<0.05). Catalase significantly inhibited the $H_2O_2$-induced augmentation of cytokine-induced $NO_2^-$ and $NO_3^-$ formation(p<0.05). But, boiled catalase did not produce a significant inhibition in comparison with the native enzyme. Another antioxidant 2-mercaptoethanol and orthophenanthroline dose-dependently suppressed $NO_2^-$ and $NO_3^-$ synthesis(p<0.05). Northern blotting demonstrated that H:02 synergistically stimulated the cytokine-induced iNOS mRNA expression in RA W264.7. Conclusion: These results suggest that $H_2O_2$ contributes to inflammatory process by augmenting the iNOS expression and nitric oxide synthesis induced by cytokines.

  • The purpose of this research was to investigate the effects of Indongdeungjikolpitang water extract(IJTE) on the complication of diabetes. IJTE did not affect the level of blood glucose in alloxan- or streptozotocin-induced hyperglycemic mice, but inhibited the motility of gastrointestine. IJTE inhibited the writhing syndrome induced by acetic acid, the permeability of evans blue into peritoneal cavity induced by acetic acid, the paw edema induced by histamine, and the formation of cotton pellet granuloma. IJTE increased the cell viability of thymocytes and splenocytes. IJTE decreased the release of ${\gamma}-interferone$(${\gamma}-IFN$) and interleukin-2(IL-2), but did not affect the release of interleukin-4(IL-4) from murine thymocytes. IJTE increased the release of IL-4 and decreased the release of tumor necrosis $factor-{\alpha}$($TNF-{\alpha}$) and $interleukin-1{\beta}$($IL-1{\beta}$), but did not affect of ${\gamma}-IFN$ and IL-2 from murine splenocytes. IJTE decreased the release of $TNF-{\alpha}$ and $IL-1{\beta}$ from murine peritoneal macrophages. IJTE decreased the production of niric oxide(NO) from murine peritioneal macrophages and increased the phagocytic activity of murine peritoneal macrophages. These results suggest that IJTE has an anti-inflammatory action via the inhibition of $TNF-{\alpha}$, $IL-1{\beta}$ and NO production from immune cells.

  • This study was to investigate the effect of high-fat diet on macrophage immunocompetence in C57BL/6 mice. C57BL/6 male mice (4 weeks aged, n=16) were divided into two groups. HD groups fed high-fat diet (45% of fat) and ND groups fed chow diet (10% of fat). Peritoneal macrophages were obtained from each mouse intra-peritoneal by sterile lavage method. Macrophage were stimulated with $1{\mu}g/ml$ of lipopolysaccharide (LPS) for 24 hr. Body weight was significantly increased by high-fat diet. Macrophage phagocytosis of HD was significantly lower than that of ND. After 24 hr of LPS stimulation, NO, IL-$1{\beta}$ and IFN-${\gamma}$ production of HD were significantly lower than those of ND. There were no significant differences in the production of TNF-${\alpha}$ and IL-12 between HD and ND. These findings suggest that high fat diet-induced obesity is associated with decreased Immunocompetence and antigen-stimulated sensitivity of peritoneal macrophage, and lower production of NO, IL-$1{\beta}$ and IFN-${\gamma}$ may contribute to these changes.

  • It confirmed the applicability as an anti-inflammatory material from Rubus occidentalis seed (RSE) extract. In HaCaT cells to evaluate the anti-inflammatory potential as a material RSE extract on the activity of the inflammatory factors caused by UVB and $IFN-{\gamma}/TNF-{\alpha}$. We measured the activity of ROS, interleukin-$1{\beta}$ ($IL-1{\beta}$), interleukin-6 (IL-6) and interleukin-8 (IL-8) by ROS-Glo $H_2O_2$ assay and ELISA kit. Our results showed that the RSE extracts inhibit the UVB and $IFN-{\gamma}/TNF-{\alpha}$-induced ROS activities and expression of $IL-1{\beta}$, IL-6 and IL-8 in a dose-dependent manner. Also it was found that inflammatory mediators of the expression of cyclooxygenase-2 (COX-2) inhibition were also brought, the expression of which is increased $PGE_2$ by COX-2 also inhibited. Finally RSE extracts measure the seed expression of filaggrin in the skin barrier, the main factor of the extract could be confirmed to increase the expression of the filaggrin damaged as a result of this concentration-dependent manner. Through this, it was able to confirm that the efficacy RSE extract to protect the inflammation by restoring the damaged layers of the epidermis. Results from more than RSE extract was able to confirm that the extract that has anti-inflammatory effects by improving the inflammation being produced from UVB.

  • Background: Cirrhosis is regarded as a possible end stage of many liver diseases, including viral infection. It occurs when healthy liver tissue becomes damaged and is replaced by scar tissue and finally may lead to hepatocellular carcinoma. Interferons (IFNs)are two general categories, type I and II. Type I includes one beta interferon and over 20 different alpha interferons. Alpha interferons are very similar in how they work, interacting with other proteins on cells like receptors. The main objective of this study was to compare Mx gene productivity post different cell line treatment with imported and Egyptian biosimilar locally produced IFNs, as well as the efficacy of those tested IFNs. Also, an assessment was made of sensitivity of different cell lines as alternatives to that recommended for evaluation of antiviral activity. Materials and Methods: Different cell lines (Vero, MDBK and Wish) were employed to evaluate cytotoxicity using the MTT assay. Antiviral activity was evaluated compared with standard IFN against VSV, Indiana strain -156, on tested rh-IFNs (imported; innovated and Egyptian biosimilar locally produced IFNs) in the pre-treated cell lines previously mentioned. The virus was propagated in the Wish cell line as recommended. Finally we estimated up-regulation of the Mx gene as a biomarker. Results: Data recorded revealed that test IFNs were safe in test cell lines. Viability was around 100%. Locally tested interferon did not realize the international potency limits, while the imported one was accepted compared with the standard IFN. These results were the same either using infectivity titer reduction assay or crystal violet staining of residual non- infected cells. Mx protein production was cell type related and confirmed by the detected Mx gene expressed in imported and locally produced IFN pre-treated cell lines. The expression of the gene was arranged in the order of Vero> wish > MDBK for the imported IFN, while for the Egyptian biosimillar locally produced one it was MDBK> Vero> wish. With regard to the antiviral activity there was a significant difference of imported IFN potency compared with the locally produced IFN (P<0.05), the IFN potential (antiviral activity) was not cell line related and showed non-significant difference for each separate product. Conclusions: Vero cells can be used as an alternative cell line for evaluation of IFN potency in case of unavailable USP recommended cell lines. Alternative potency evaluation assay could be used and proved significant difference in IFN potency in case of local and imported agents. Evaluation of antiviral activity could be used in parallel to viral infectivity reduction assay for better accuracy. Mx gene can be used as a marker for IFN potential.
