The growth and synthetic activities of fibroblasts are regulated by cytokines and growth factors derived from activated inflammatory cells. Stimulatory effect of low level laser (LLL) radiation on wound healing seems to be in part due to direct stimulatory action on cell proliferation and synthetic activities of fibroblasts. Also indirect stimulatory effect on the fibroblast function through inflammatory or immune cells is another possible mechanism of biostimulatory action of LLL. This study was performed to determine the growth rate of human gingival fibroblasts obtained biopsy and culture, fibroblast cell line, and immune cell line by using $[^3H]-$ thymidine incorporation test. And gene expression pattern was also analyzed by using the DNA probe such as Hsp70, IL-1$\beta$, MIP-1$\alpha$ and actin cDNA. Proliferation rate of gingival fibroblast was increased by LLL irradiation, but no more effect was added by LPS or IL-1$\beta$ pretreatment Enhanced Hsp70 gene expression was found from gingival fibroblasts and fibroblast cell line COS by LLL irradiation., which was not more increased by LPS or IL-1$\beta$ pretreatment. LLL-irradiated promyelcytic cell line HL-60 and macrophage cell line RAW264.7 showed significant stimulatory effect of proliferation rate when compared with respective control. However there were no changes in growth rate of other immune cell tested in this study, such as B cell line WR19n.l and 230, helper T cell line Jurkat and Hut78, cytolytic T cell line CTLL-r8. By LLL-irradiation Hsp70 gene expression was increased in RAW246.7 and HL-60, not in CTLL-R8. And IL-1$\beta$ and MIP-1$\alpha$ gene expression were induced only from LLL-irradiated RAW264.7. These results led us to presume that LLL radiation may affect to the immune cells, especially to macrophage, through which it might promote wound healing process.

Panax ginseng C. A. Meyer is well known as traditional herbal medicine, and ginseng berries are known to exhibit potential immune-enhancing functions. However, little is known about the in vivo immunomodulatory activity of Korean ginseng berries. In this study, crude Korean ginseng berries polysaccharides (GBP) were isolated and their immunomodulatory activities were investigated using cyclophosphamide (CY)-induced immunosuppressive BALB/c mice. In CY-treated mice, oral administration of GBP (50-500 mg/kg BW) remarkably increased their spleen sizes and spleen indices and activated NK cell activities. GBP also resulted in the proliferation of splenic lymphocytes (coordinating with ConA: plant mitogen which is known to stimulate T-cell or LPS: endotoxin which binds receptor complex in B cells to promote the secretion of pro-inflammatory cytokines) in a dose-dependent manner. In addition, GBP significantly stimulated mRNA expression levels of immune-associated genes including interleukin-1β (IL-1β), IL-2, IL-4, IL-6, tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), toll-like receptor 4 (TLR-4), and cyclooxygenase-2 (COX-2) in CY-treated mice. These results indicate that GBP is involved in immune effects against CY-induced immunosuppression. Thus, GBP could be developed as an immunomodulation agent for medicinal or functional food application.

Antimicrobial peptides/proteins are ancient and naturally-occurring antibiotics in innate immune responses in a variety of organisms. Additionally, these peptides have been recognized as important signaling molecules in regulation of both innate and adaptive immunity. During mycobacterial infection, antimicrobial peptides including cathelicidin, defensin, and hepcidin have antimicrobial activities against mycobacteria, making them promising candidates for future drug development. Additionally, antimicrobial peptides act as immunomodulators in infectious and inflammatory conditions. Multiple crucial functions of cathelicidins in antimycobacterial immune defense have been characterized not only in terms of direct killing of mycobacteria but also as innate immune regulators, i.e., in secretion of cytokines and chemokines, and mediating autophagy activation. Defensin families are also important during mycobacterial infection and contribute to antimycobacterial defense and inhibition of mycobacterial growth both in vitro and in vivo. Hepcidin, although its role in mycobacterial infection has not yet been characterized, exerts antimycobacterial effects in activated macrophages. The present review focuses on recent efforts to elucidate the roles of host defense peptides in innate immunity to mycobacteria.

Effects of the butanl fraction of Astragali Radix (BFAR) on the cellular and nonspecific immune responses were investigated in ICR mice. Mice were divided into 4 groups and BFAR at doses of 5, 25 and 125 mg/kg u ere administered orally to mice daily for 3 weeks, and the normal animals were given vehicle. The results of this study are summarized as follows; the relative weight of thymus was greatly increased by BFAR treatment, compared with that in mormal mice. However, the body weight gain was not affected. Delayed-type hypersensitivity (DTH) reaction to sheep red blood cells (SRBC) for cellular immunity was significantly enhanced by BFAR treatment, compared with those in normal mice. In these mice, BFAR also dose-dependently increased activities of phagocyte and natural killer (NK) cells as well as the number of leukocyte resulted from nonspecific immunity Thus, these results demonstrate that BFAF treatment results in a significant increase in both cellular and nonspecific immune responses to antigen in concentrations that enhance humoral immune function.

In this study, we investigated the immunopotent activities of lepidan, a water soluble proteoglycan from Lentinus lepideus. To examine whether lepidan may affect nonspecific immune responses, we determined the effect on the production of nitric oxide (NO). Lepidan effectively increased the NO production in IFN-${\gamma}$ and LPS triggered RAW 264.7 cells. To further demonstrate the evidence that lepidan activates various immune cells, we determined the alkaline phosphatase activity, plaque-forming cell number and secretion of interleukine-4 (IL-4) and granulocyte/macrophage-colony stimulating factor (GM-CSF) after lepidan treatment in murine splenocytes. The results showed that lepidan increased alkaline phosphatase activity and the number of plaque-forming cells, which indicates that lepidan can lead B lymphocytes to late stage of differentiation. Also, when the splenocytes were cultured with lepidan for 48 hr, the level of IL-4 and GM-CSF in the supernatant dramatically increased. Taken together, these data suggest that lepidan is a biological response modulator that is able to activate immune responses.

Objective : Immune potentiation including activation of T cells, B cells, macrophages, and dendritic cells is known to play a key role in prevention and treatment of patients with cancer. In this study, we investigated the effects of Acanthopanax sessiliflorus (AR) on the immune system, especially on thymocytes, splenocytes, and macrophages. Methods : We investigated the effects of AR on proliferation of splenocytes in normal mice, and the effects on proliferation of splenocytes and thymocytes in tumor-bearing mice. In addition, the effect of AR on NO production using macrophages was investigated. Results : Treatment with AR accelerated proliferation of splenocytes in vitro. AR also accelerated thymocyte proliferation, but did not affect splenocytes proliferation in normal mice. In contrast, AR accelerated proliferation of splenocytes and thymocytes significantly in tumor bearing mice. In addition, NO production level from macrophages was elevated by treatment with AR. Conclusion : These results demonstrate that AR has anti-cancer activities and related mechanisms are involved in immune potentiation such as acceleration of immune cell proliferation and elevation of NO production level in macrophages. In addition, we also demonstrate the possibilities of AR as complementary and alternative medicine to standard anti-cancer drugs.

Objectives: This study was performed to develop therapeutic prescription that is more significant than existing ones through extraction method and formulation changes. Methods: Yukmijihwangtang(YMJHT) was extracted in 80% ethanol, and their relative anti-oxidant activities as well as anti-inflammatory effects through immune modulation were measured. Results: Both water and ethanol extracted YMJHT showed does-dependent DPPH elimination activities. ROS inhibition activity was greater in water extracted YMJHT except for Moutan Cortex. NO inhibition assay results indicated that all groups showed higher NO inhibition activities in RAW 264.7 cells in dose dependent manner. Water extracted group showed higher NO inhibition activity than that of ethanol extracted group. TNF-${\alpha}$ secretion inhibition assay using RAW 264.7 cells, water extracted YMJHT showed higher activity than ethanol extracts. Growth rate of spleen cells was greater in all tested groups, with higher rate in YMJHT-EtOH than YMJHT-DW. Suppression of gene expression of IFN-r in spleen cells stimulated by Con A was higher in YMJHT-EtOH than YMJHT-DW. Suppression of gene expression of IL-10 in spleen cells stimulated by Con A was highest in YMJHT-DW with 40%. Suppression of gene expression of IL-4 in spleen cells stimulated by Con A were significant with 90% or higher in all groups and that of IL-12p35 were also higher than 90% in all cases. Conclusions: From the results, it shows that YMJHT has anti-inflammatory effects through immune modulation. However, the difference between YMJHT-EtOH and YMJHT-DW was not that significant. Further studies are needed to find out effective extraction methods of herbal medicine.

The study was performed using of ethanol and water extracts of Fatsia japonica Decne. et Planch. in anticancer and immune activities. All extracts of 1.0 $g/{\ell}$ concentration were increased in over 60% of the anticancer activites in A549 and MCF7 cells. Root barks inhibited 55%, 74% in A549 and MCF7 cell by adding ethanol extracts of $g/{\ell}$ concentration. The cytotoxicity of human lung nomal cell (HEL299) counted up to about 22% for ethanol extracts of root barks in 1 $g/{\ell}$ concentration. The activity of human immune T and B cells were increased up to $140{\sim}170%$ by adding ethanol extract of the root barks. Increasing trend of secretion of cytokine (IL-6, $TNF-{\alpha}$) from human B and T cell for 5 days cultivation has been abserved. From the results, the anticancer and immune-stimulatory activities of the roots extract were higher than the extracts of other parts.

Immune activities of two different extracts of Kadsura japonica Dunal. by typical extraction processes using water and ethanol at 60 $^{\circ}$C and 100 $^{\circ}$C were compared to them by ultrasofication system and through traditional fermemtation process. The fermented broth Kadsura japonica Dunal. definitely improved the growth of human B and T cell up to 30% and 22%, respectively, compared to the control. The secretion of TNF-${\alpha}$ and IL-60 was also enhanced by the addition of the fermented broth, up to 35%. NK cell activation was significantly improved up to 1.4 times higher than the case of adding other extracts. It was also found that this broth could yield higher nitric oxide production from macrophage than Lipopolysaccharides (LPS). It can be concluded that Kadsura japonica has immune activities and, in general, the culture broth from a conventional fermentation has higher immune activities, possibly by yielding immuno-modulatory compounds, not existed in typcial extraction systems as the result of HPLC analysis.
