This study was performed to investigate the immunopotentiative effects of conjugated linoleic acid on mice immunosuppressed by administratin corticoids. Mice were divided into four groups of 8 mice. Two groups (C, CP) were given diet supplemented with 1% linoleic acid (CLA) and the other two groups (L, LP) were given diet supplemented with 1% linoleic acid (LA) instead of CLA. Prednison was administered to two groups (CP, LP) for immune depression. After feeding diets for 3 weeks containing PDS injection for last 1 week. Serum and gut lumen lavage were taken. Measurement of total Ig were executed using sandwich ELISA. Serum levels of IgA, IgG, and IgM showed some trend which groups fed with CLA were higher than groups fed with LA while IgE was reduced in those fed the CLA intake, and groups administered with PDS were lower than groups administered with saline. However, no significant differences were seen in the proportion of total immunoglobulin in serum. In case of secretory IgA, Group C and CP were significantly higher than group L and LP. Especially between CP and LP, it can be seen effects of CLA. In addition that the CLA treated group weighted a significantly lower level than the one's that have not been treated with CLA. These result support the view that CLA potentiate the immune response and prevent immune depression caused by administrating of corticoids. In conclusion, CLA produced a situation favorable for immunopotentiative effects. Thus, the clinical application of CLA is warranted.

Objective : To observe the efficacy and safety of CheungYeolYiSeup-tang and Hwangbaek external dressings on dampness-heat pattern atopic dermatitis(AD) in a non-comparative study. Methods : 10 patients with AD were included for 4 weeks of treatment. Efficacy and safety assessment included the scoring atopic dermatitis index(SCORAD), typical signs and symptoms of AD, results of some laboratory tests related to toxicity, and the incidence of adverse events. Results : Improvements in efficacy parameters were observed and produced no significant changes in laboratory tests related to toxicity in these patients. Their SCORAD results significantly decreased after 4weeks(P value<.01, according to the Wilcoxon sum of ranks test). Similarly, significant reductions from baseline in subjective pruritus scores and (P value<.05 by the Wilcoxon sum of ranks test) and the mean average of individual signs and symptoms of AD were reported after 4 weeks(P value<.05, P<0.01 by the Wilcoxon sum of ranks test). There were no significant changes in eosinophil, neutrophil, lymphocyte, immunoglobulin E and ESR in blood serum by paired ttest. Conclusion :CheungYeolYiSeup-tang administration and Hwangbaek external dressings are an effective and safe treatment for the management of dampness-heat pattern atopic dermatitis.

Lupus anticoagulant-hypoprothrombinemia syndrome (LAHPS), a very rare disease that is caused by the presence of antifactor II antibodies, is usually counterbalanced by the prothrombotic effect of lupus anticoagulant (LAC). Patients with LAHPS are treated using fresh frozen plasma, steroids, immunosuppressive agents, and immunoglobulins for managing the disease and controlling hemorrhages. Notably, steroids are the important treatment for treating hypoprothrombinemia and controlling the bleeding. However, some patients suffer from severe, life-threatening hemorrhages, when factor II levels remain very low in spite of treatment with steroids. Here, we report a case of LAHPS in a 15-year-old girl who experienced pulmonary hemorrhage with rapid progression. She was referred to our hospital owing to easy bruising and prolonged bleeding. She was diagnosed with LAHPS that presented with pancytopenia, positive antinuclear antibody, proloned prothrombin time, activated partial thromboplastin time, positive LAC antibody, and factor II deficiency. Her treatment included massive blood transfusion, high-dose methylprednisolone, vitamin K, and immunoglobulin. However, she died due to uncontrolled pulmonary hemorrhage.

Asthma, remains symptomatic despite ongoing treatment with high doses of inhaled corticosteroids (ICS) in conjunction with long-acting beta-agonists (LABA), is classified as "severe" asthma. In the course of caring for those patients diagnosed with severe asthma, stepping up from ICS/LABA to more aggressive therapeutic measures would be justified, though several aspects have to be checked in advance (including inhaler technique, adherence to therapy, and possible associated comorbidities). That accomplished, it would be advisable to step up care in accordance with the Global Initiative for Asthma (GINA) recommendations. Possible strategies include the addition of a leukotriene receptor antagonist or tiotropium (to the treatment regimen). The latter has been shown to be effective in the management of several subgroups of asthma. Oral corticosteroids have commonly been used for the treatment of patients with severe asthma in the past; however, the use of oral corticosteroids is commonly associated with corticosteroid-related adverse events and comorbidities. Therefore, according to GINA 2017 these patients should be referred to experts who specialize in the treatment of severe asthma to check further therapeutic options including biologics before starting treatment with oral corticosteroids.

In order to investigate the therapeutic effect of SSC, NC/Nga animal model resembling the AD-like symptoms were used to measure the changes in cytokines and histology. SSC prescription group showed significant decrease in the atopic dermatitis clinical index by 40.2% compared to that of the control. The SSC prescription had significant effect on immune cells that are related to inducing AD symptoms. SSC prescription also increased the ratio of immune cells in DLN that were not directly involved in AD symptoms. SSC prescription group showed significant decrease in the level of cytokines within spleen cells and DLN. The prescription also decreased the level of immunoglobulin IgE levels in serum by 25.3%. The thickness of epidermis and dermis as well as the precipitation of erythrocytes were also observed. The results indicate the therapeutic effect of SSC in the treatment of atopic dermatitis through immune modulation. The study will provide a broader applications in the treatment of atopic dermatitis. Particularly, skin regeneration effect and supplemental use of topical application of SS in atopic dermatitis treatment had been reported previously, and further investigation on the dose dependent effect as well as skin irritation studies of SS should be followed.

In this report, we investigated the effect of aqueous extract of vinegar treated small black soybean (Glycine max Merr.) (Leguminosae) (VSBS) on mast cell-mediated allergic reaction and pro-inflammatory cytokine secretion. VSBS inhibited compound 48/80-induced systemic reactions. VSBS attenuated immunoglobulin (Ig) E-mediated passive cutaneous anaphylaxis. In addition, VSBS decreased the phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated secretion of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6 and interleukin (IL)-8 in human mast cells. Our findings provide evidence that VSBS inhibits mast cell-derived allergic reactions.

Inflammation that is considered to be mainly related to pathogenesis of atopic dermatitis (AD) is the biological response of a host to stimuli, such as cellular injury or infection. In this study, we investigated the anti-inflammatory and anti-oxidative activities of white ginseng roots by ultra high pressure extraction (Gin-UHP), fermentation followed by ultra high pressure extraction (Gin-UHPF), and polyol extraction (Gin-POL). As a result, ginseng extracts were able to decrease the secretion of pro-inflammatory cytokines (interleukin-8 and tumor necrosis factor-alpha) and immunoglobulin E. Also, Gin-POL had the highest DPPH radical scavenging activity and when we compared the SOD-like activity, Gin-UHP had the highest. Moreover, we looked into the effect of these ginseng extracts on anti-aging to show the possible usefulness as a raw material of cosmetics. As a result, ginseng extracts were able to reduce the production of melanin, and inhibit the tyrosinase and elastase activities in a dose-dependent manner. The extracts also decreased the expression of MMP-1 and had a significant hyaluronidase inhibitory activity. Taken together, these results demonstrate that ginseng extracts may have an improvement effect on AD by using its anti-inflammatory and antioxidant properties.

Allergic asthma, is a common chronic inflammatory disease of the airway presenting with airway hyperresponsiveness and airway remodelling. T helper cells-derived cytokines are critically associated with asthma pathogenesis. Janus kinase-signal transduction and activation of transcription (JAK/STAT) signaling is found to be involved in asthma. Magnolol is a plant-derived bioactive compound with several pharmacological effects. The study aimed to assess the effects of magnolol in ovalbumin (OVA)-induced asthmatic model. BALB/c mice were sensitized and challenged with OVA. Magnolol (12.5, 25, or 50 mg/kg body weight) was administered to separate groups of animals. Dexamethasone was used as the positive control. Cellular infiltration into the bronchoalveolar lavage fluid (BALF) were reduced on magnolol treatment. The levels of Th2 and Th17 cytokines were reduced with noticeably raised levels of interferon gamma. Lung function was improved effectively along with restoration of bronchial tissue architecture. OVA-specific immunoglobulin E levels in serum and BALF were decreased by magnolol. Magnolol reduced Th17 cell population and effectively modulated the JAK-STAT and Notch 1 signaling. The results suggest the promising use of magnolol in therapy for allergic asthma.
