Purpose : This study is to examine the effects of Hwaganjeon water extract(HGJ) on immobilization-stress or cold-stress in BALB/C mice. Methods : We have Hwaganjeon water extract(HGJ) by freeze-dryer & melt it by a saline solution. We feed HGJ 500mg/Kg to 5mice, and add immobilization-stress by putting mice in plastic cylinder 10 hours, and add cold-stress by putting mice in $4^{\circ}C$ cold room 6 hours. Results : 1. HGJ decreased the serum level of histamine and corticosterone increased by immobilization-stress or cold-stress. HGJ inhibited the release of histamine from mast cells at the concentration of 1 mg/ml. 2. HGJ did not affect the cell viability of thymocytes decreased by immobilization-stress or cold-stress, but increased the cell viability of splenocytes decreased by immobilization-stress or cold-stress. 3. HGJ decreased the population of splenic $CD4^{+}$ and $CD8^{+}$cells increased by immobolization-stress or cold-stress. 4. HGJ enhanced the production of ${\gamma}$-interferon(IFN) and interleukin(IL)-2 decreased by immobilization-stress or cold-stress. Conclusion : These results indicate that HGJ may be useful for the prevention and treatment of stress via suppression of serum histamine and corticosterone level and enhancement of immune response.

The purpose of this study was to investigate the anti-allergy activities of persimmon leaf extract (PLE) on a phthalic anhydride (PA)-induced allergic mouse model. A human leukemic mast cell line (HMC-1) was used to examine the inhibitory activity of PLE on the histamine release by human leukemic mast cells. PLE inhibited histamine release from HMC-1 cells in response to cross-linkage of high-affinity IgE receptor-${\alpha}$ ($Fc{\varepsilon}RI{\alpha}$). Additionally, a PA-induced allergic mouse model was used to investigate the effects of PLE in vivo. Mice were orally administrated with or without PLE of single dose (250 mg/kg/day) for 31 days. Oral intake of PLE significantly inhibited passive cutaneous reactions. Oral administration of PLE to PA-induced allergic mice also led to a striking suppression of the development of contact dermatitis, ear swelling and lymph node weight. In addition, PA-specific IL-4 production of draining lymph node cells was markedly diminished by PLE oral administration, but not IFN-${\gamma}$. Furthermore, PLE treatment suppressed PA-induced thymus and activation-regulated chemokine (CCL17) and cutaneous T cell-attracting chemokine (CCL27) expressions in ear tissues. Based on these results, we suggest that PLE may have therapeutic potential as an effective material for management of irritant contact dermatitis or related inflammatory diseases.

Cyclic AMP-responsive element binding protein (CREB) is known to be associated with angiogenesis. In the present study we investigated the possible role of CREB in the expression of vascular endothelial growth factor (VEGF) by mouse macrophages. Over-expression of CREB increased VEGF secretion by cells of the RAW264.7 mouse macrophage cell line. It also increased the promoter activity of a mouse reporter driven by the VEGF promoter, while a dominant negative CREB (DN-CREB) abrogated the activity, suggesting that CREB mediates VEGF transcription. Forskolin, an adenylyl cyclase activator, stimulated VEGF transcription, and the PKA inhibitor H89 abolished this effect. IFN-${\gamma}$, a potent cytokine, stimulated VEGF expression only in part through the PKA-CREB pathway. These results indicate that PKA phosphorylates CREB and so induces VEGF gene expression. An analysis of mutant promoters revealed that one of the putative CREB responsive elements (CREs), at -399 ~ -388 in the promoter, is critical for CREB-mediated VEGF promoter activity, and the significance of this CRE was confirmed by chromatin immunoprecipitation assays.

House dust mite (HDM) as a major allergen and damage-associated molecular pattern (DAMP) such as S100A8 and S100A9 trigger the pathogenesis and severity of allergic disease such as asthma. Regulation of neutrophil apoptosis is an important immune response and its dysregulation is involved in pathogenesis of allergic diseases. In this study, we examined the effects of HDM, S100A8 and S100A9 on spontaneous apoptosis of normal neutrophils. We considered the importance of the difference between in vitro and in vivo results and developed a new in vitro system consisting of a combination of immune cells and T helper (Th) cytokines. Extract of Dermatophagoides pteronyssinus (DP), S100A8, and S100A9 inhibited neutrophil apoptosis in culture of neutrophils alone without other leukocytes. DP and S100A8 more strongly suppressed neutrophil apoptosis in combinations of neutrophils, eosinophils, lymphocytes or monocytes than in a culture of neutrophils alone. Anti-apoptotic effect of S100A9 in the mixture of immune cells was similar to that in neutrophils. DP, S100A8, and S100A9 blocked neutrophil apoptosis, regardless of pretreatment with a T helper (Th) 1 cytokine (IFN-$\gamma$), Th2 cytokines (IL-4 and IL-10), a Th9 cytokine (IL-9), a Th17 cytokine (IL-17), a Treg-producing cytokine (TGF-$\beta$). These findings may enable elucidation of allergy pathogenesis due to HDM and DAMP.

Atopic dermatitis (AD) is a chronic inflammatory skin disease with a complex etiology that encompasses immunologic responses. AD is frequently associated with elevated immunoglobulin (Ig) E levels, and common environmental factors contribute to its pathogenesis. Several recent studies have documented the role of specific lactic acid bacteria in the treatment and prevention of AD in humans and mice. In this study, the efficacy of Duolac ATP, a probiotic preparation, was determined in a mouse model with AD-like skin lesions. Alterations in the cytokine levels and histological staining suggested the alleviation of AD. The in vivo test showed that T helper (Th)2 cytokines, IgE, interleukin (IL)-4, and IL-5, were significantly downregulated, whereas Th1 cytokines, IL-12p40 and interferon (IFN)-${\gamma}$, were upregulated in all groups of mice treated with Duolac ATP compared to that observed in the group of mice treated with 1-chloro-2,4-dinitrobenzene (DNCB) alone. Moreover, the scratch score decreased in all mice treated with Duolac ATP. Staining of the dorsal area of the mice in each group with hematoxylin and eosin and toluidine blue further confirmed the alleviation of AD in mice orally treated with Duolac ATP. These results suggest that Duolac ATP inhibits the development of AD-like skin lesions in NC/Nga mice by suppressing the Th2 cell response and increasing the Th1 cell response. Thus, Duolac ATP is beneficial and effective for the treatment of AD-like skin lesions.

Objectives: This study was aimed to analyze the correlation of clinical characteristics of cancer patients treated with Korean Medicine and their natural killer cell activity (NKA). Methods: The medical records of 52 cancer patients who conducted NKA test at Cheonan Korean Medicine Hospital of Daejeon University from March 2016 to May 2018 were reviewed. NKA was determined at Seegene Medical institute using NK Vue Gold(R) kit, evaluating activated $IFN-{\gamma}$ by enzyme immunoassay after incubation of whole blood. Careful investigations were conducted by categorizing the patients by their sex, origin, stage, ECOG scale, and conventional treatment type. We used data from the medical records and statistical analysis using SPSS 25.0 V. Results: The average NKA of all patients was $623.1{\pm}722.0pg/mL$. The NKA value was higher for females than for males. No correlation was evident between age and NKA, but patients aged over 70 years had the lowest NKA average result. Stage III and IV patients showed clearly lower NKA values when compared to stage I and II patients. NKA and ECOG scale values showed no evident relationship. Conclusions: This study presented the characteristics of NKA in cancer patients treated with Korean medicine. The NKA result differed by gender and stage. Based on these findings, further study is needed regarding the clinical meaning of NKA.

The object of this study was to observe anticancer and related immunomodulatory and anticachexic effects of Insamyangyoung-tang aqueous extracts (ISYYTe) on non-small cell lung carcinoma (squamous epithelial carcinoma), NCI-H520, xenograft Balb/c nu-nu nude mice. Changes on the tumor volume and weights, lymphatic organ(spleen and popliteal lymph node), serum interferon (IFN)-${\gamma}$ levels, splenocytes and peritoneal macrophage activities (NK cell activity), splenic tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$ and IL-10 contents, splenic T-lymphocyte subsets (CD3+, CD4+ and CD8+) and TNF-${\alpha}+$ cells were observed with tumor mass and lymphatic organ histopathology to detect anticancer and immunomodulatory effects. In addition, changes on the body weights, epididymal fat weights and serum IL-6 levels were also detected with the thicknesses of deposited cervical brown adipose tissue and their mean diameters to monitor the tumor-related anticachexic effects. The results obtained in this study suggest that over 50 mg/kg of ISYYTe showed favorable anticancer effects on the NCI-H520 cell xenograft with immunomodulatory and anticachexic effects. However, detail mechanism studies should be conducted in future with the screening of the biological active compounds in this herb.

In order to screen new allogeneic mixed lymphocyte culture (allo-MLR) inhibitor which is expected to be immunomodulating drug lead, we have investigated allo-MLR inhibitory activity on the marine-derived symbiotic microorganisms (1,895 strains) from the marine algae. The potent inhibitory activities (over 45% inhibition of proliferation at 10 and 2 ${\mu}g/ml$) without cytotoxicity were observed in the extracts of 46 strains. While, the significant stimulating activities (over 100% proliferation at 10 and 2 ${\mu}g/ml$) without cytotoxicity were observed in the extracts of 5 strains. In the second assay using 46 bioactive strains, 14 strains exhibited again significant allo-MLR inhibitory activity. Finally, 11 strains among the 14 strains inhibited proliferation and IFN-${\gamma}$ production of CD4+ T cells during the stimulation with specific antigen in the third assay. On the basis of above results, the marine algae is nice source for isolation of immunomodulating microorganism, and the marine algae-associated microorganism is also nice target for development of the new immunomodulating drug lead.
