Background: Circulating lymphocyte subsets reflect the immunological status and might therefore be a prognostic indicator in cancer patients. Our aim was to evaluate the clinical significance of circulating lymphocyte subset in gastric cancer (GC) cases. Methods: A retrospective study on a prevalent cohort of 846 GC patients hospitalized at Hospital from Aug 2006 to Jul 2010 was conducted. We calculated the patient's disease free survival (DFS) after first hospital admission, and hazard ratios (HR) from the Cox proportional hazards model. Results: Our findings indicated a significantly decreased percentage of CD3+, and CD8+ cells, a significantly increased proportion of $CD4^+$, $CD19^+$, $CD44^+$, $CD25^+$, NK cells, and an increased $CD4^+/CD8^+$ ratio in GC patients as compared with healthy controls (all P < 0.05). Alteration of lymphocyte subsets was positively correlated with sex, age, smoking, tumor stage and distant metastasis of GC patients (all P<0.05). Follow-up analysis indicated significantly higher DFS for patients with high circulating $CD19^+$ lymphocytes compared to those with low $CD19^+$ lymphocytes (P=0.037), with $CD19^+$ showing an important cutoff of $7.91{\pm}2.98%$ Conclusion: Circulating lymphocyte subsets in GC patients are significantly changed, and elevated CD19+ cells may predict a favorable survival.

Objectives: Three yin-tonifying formulae (Ssanghwa-tang, Yukmijihwang-tang and Jaeumganghwa-tang) were applied to investigate their immunological activities on antigen (Ag)-specific or Ag-non-specific immune responses in the murine macrophage cell line (RAW 264.7) and in ovalbumin (OVA)-immunized mice. Methods: This study was carried out in nitricoxide (NO) synthesis in RAW 264.7 cells and cellular proliferation in mouse splenocytes in association with three herbal formulas. C57BL/6 mice were immunized intraperitoneally with OVA/aluminum ($100\;{\mu}g/200\;{\mu}g$/mouse) on days 1, 8, and 15. Three herbal formulas were administrated to mice orally for 3 weeks from day 1. On day 22, OVA-, lipopolysaccharide (LPS)-, and concanavalin A (Con A)-stimulated splenocyte proliferation and antibodies (OVA-specific antibodies of the IgG, IgG1, and total IgM classes) in plasma were measured. Results: All three yin-tonifying formulas significantly enhanced cellular proliferation by LPS and Con A in splenocytes from OVA-immunized mice (p<0.001). Also, these herbal formulas all significantly enhanced plasma OVA-specific IgG, IgG1, and total IgM levels compared with the OVA/Alum group. Conclusion: These results suggested that the three yin-tonifying formulae could be used as stimulators of immune response.

Garlic generally becomes coinfected with several types of viruses belonging to the Potyvirus, Carlavirus, and Allexivirus genera. These viruses produce characteristically similar symptoms, they cannot be easily identified by electron microscopy (EM) or immunological detection methods, and they are currently widespread around the world, thereby affecting crop yields and crop quality adversely. For the early and reliable detection of garlic viruses, virus-specific sets of primers, including species-specific and genus-specific primers were designed. To effectively detect the twelve different types of garlic viruses, primer mixtures were tested and divided into two independent sets for multiplex polymerase chain reaction (PCR). The multiplex PCR assays were able to detect specific targets up to the similar dilution series with monoplex reverse transcription (RT)-PCR. Seventy-two field samples collected by the Gyeongbuk Agricultural Technology Administration were analyzed by multiplex RT-PCR. All seventy two samples were infected with at least one virus, and the coinfection rate was 78%. We conclude that the simultaneous detection system developed in this study can effectively detect and differentiate mixed viral infections in garlic.

Background : Asthma is a chronic inflammatory disorder under immunological influence. Gamichunggumgangwha-tang (CG, Jiaweiqingjinjianghuo-tang) and Gamiyukmigiwhang-tang (YM, Jiaweiliuweidihuang-tang) are herbal tonics for asthma from traditional herbal medicine. Objective : To evaluate the effect of CG and YM on immune cell & serum OA-specific IgE in broncho-alveolar lavage fluid (BALF) in a rat asthma model. Materials and Methods : Rats were sensitized with OA; at day I sensitized group and CG and YM groups were systemically immunized by subcutaneous injection of 1mg OA and 300mg of Al(OH)3 in a total volume of 2ml. At the same time, 1 ml of 0.9% saline containing $6{\times}10^9$ B. pertussis bacilli was injected by Lp. 14 days after the systemic immunization, rats received local immunization by inhaling 0.9% saline aerosol containing 2% (wt/vol) OA. A day after local immunization, BALF was collected from the rats. Rats were orally administered with each of CG and YM extract for 14 days since the day after local immunization. Lymphocyte, CD4＋ T cell and CD8＋ T cell counts, CD4＋/CD8＋ ratio in BALF, change of serum OA-specific IgE level, CD4＋ T cell and CD8＋ T cell percentages in the peripheral blood were measured and evaluated. Results : CG and YM showed an alleviating effect on asthmatic responses of rats. CG decreased total cell, lymphocyte, CD4＋ T cells in BALF, and serum OA-specific IgE level as compared with the control group. YM decreased lymphocytes as compared with the control group. CD4＋/CD8＋ ratio in BALF from the CG and YM groups and serum OA-specific IgE level from the YM group didn't show any significant variation from the control group. Conclusion : CG alleviated asthmatic hyperreactivity of the immune system through CD4＋ T cells and serum IgE. Further the study of this immune system modulating mechanism is expected.

Objectives: Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive disorder. These patients lose their teeth at a young age and are in need of prosthetic rehabilitation. The aim of this systematic review was to assess the success of dental implant placement in these patients. Materials and Methods: An electronic search was performed in PubMed Central, Scopus, and Web of Science using the keyword "Papillon-Lefèvre syndrome" AND "dental implant" OR "prosthodontics". Articles reporting implant placement in patients with PLS until July 2019 were included. Results: Assessment of the included 11 articles reporting 15 cases showed 136 implant placements in these patients. Implant failure occurred in 3 patients (20 implants). The peri-implantitis and failure rate was higher in the maxilla. Meta-analysis showed the probability of failure to be 7% (95% confidence interval [CI] 0%-31%) for maxillary implants and 2% (95% CI 0%-9%) for mandibular implants. The follow-up time ranged between 1 and 20 years. Healing after bone graft and implant placement in these patients was uneventful. Conclusion: Dental implants may be a viable treatment option for PLS patients. Implantation can help preserve alveolar bone if the patients' immunological and growing conditions are well-considered and proper oral hygiene and compliance with the maintenance program are continued.

Purpose: To evaluate whether the levels of immunoglobulin G (IgG) antibody to Tanerella forsythia are associated with periodontal status. Methods: Patients with a diagnosis of chronic periodontitis were considered candidates for the study; thus 80 chronic periodontitis patients and 28 healthy persons (control group) were invited to participate in this investigation. The presence of T. forsythia was detected by polymerase chain reaction (PCR) analysis using primers designed to target the respective 16S rRNA gene sequences. Peripheral blood was collected from each subject to identify the IgG1 and IgG2 serum antibodies against T. forsythia. All microbiological and immunological laboratory processes were completed blindly, without awareness of the clinical status of the study patients or of the periodontal sites tested. Results: The bivariate analysis showed that lower mean levels of clinical attachment level (CAL) and probing depth were found in the presence of the IgG1 antibody titers against whole-cell T. forsythia; however, only the difference in CAL was statistically significant. In the presence of the IgG2 antibody titers against whole-cell T. forsythia, the periodontal parameters evaluated were higher but they did not show statistical differences, except for plaque. The unadjusted linear regression model showed that the IgG1 antibody against whole-cell T. forsythia in periodontitis patients was associated with a lower mean CAL (${\beta}=-0.654$; 95% confidence interval [CI], -1.27 to -0.28; P<0.05). This statistically significant association remained after adjusting for possible confounders (${\beta}=-0.655$; 95% CI, -1.28 to -0.29; P<0.05). On the other hand, smoking was a statistically significant risk factor in the model (${\beta}=0.704$; 95% CI, 0.24 to 1.38; P<0.05). Conclusions: Significantly lower mean levels of CAL were shown in the presence of the IgG1 antibody titers against whole-cell T. forsythia in periodontitis patients. Thus, the results of this study suggest that IgG1 antibody to T. forsythia may have been a protective factor from periodontitis in this sample.

Objectives : The aim of this study was to investigative the effects of Gagambojungikgi-tang (GBT), a Korean herbal medicine, on the immune mediators, T cell proliferation and wound healing in the recombinant Sj26 (rSj26) antigen induced atopic dermatitis(AD) model mice. Methods : GBT is the water extracts prepared from mixture of Ginseng Radix, Astragali Radix, Angelicae gigantis Radix, Atractylodes Rhizoma alba, Aurantii nobilis Pericarpium, Glycyrrhizae Radix, Artemisia iwayomogi Herba, Scutellaria Radix, Lonicera japonica Flos. This is a modified prescription of Bojungikgi-tang, which has been used for the treatment of indigestion, and immunological disease in east-asian countries. GBT was orally administered or externally applied at difference doses. The levels of immune mediators [(IgE, IgG1, prostaglandin E2 (PGE2), Th1/Th2 cytokines], T cell proliferation, and wound healing in the rSj26 or chemical antigen induced AD model BALB/c were investigated. Results : GBT dose-dependently suppressed the release of TNF-${\alpha}$, IL-$1{\beta}$ (Th1 cytokines), IL-4, IL-10 (Th2 cytokines), PGE2 (inflammatory mediators) and T cell proliferation. But GBT increased the production of IFN-${\gamma}$ (Th1 cytokine). Furthermore, A wound healing effect of GBT was similar to external application of dexamethasone. Conclusions : These results suggest that GBT suppresses the inflammatory mediators and regulates the Thl/Th2 cytokines, and promotes the wound healing. Therefore, these properties may contribute to the strong anti-AD effect of GBT.

Purpose : This study was to investigate the effects of Dohongsamul-tang extract on the rat with an surgically induced endometriosis. Methods : Four weeks after the operation for inducing the endometriosis to a matured female rat, the normal hyperplasia of the transplanted endometrium was identified in anatomico-histological aspects. By dividing each of the control group and Dohongsamul-tang administered experimental group into 8 rats, Dohongsamul-tang concentrates were administered orally to the experimental group with 1g/1ml/200g everyday for 40 days and then images were taken from the macroscopic tissues which were transplanted to the mesenterium, and the concentrations of progesterone, estradiol, tumor necrosis $factor-{\alpha}(TNF-{\alpha})$, and interleukin(IL)(-2, -4, -6, and -10) in the serum were measured. Results : Transplanted endometrium tissues showed the histological findings in accordance with the normal endometrium tissues and from the macroscopic findings the size of transplanted endometrium tissues showed a definite decrease. Compared to the control group, the experimental group showed significant decreases in the values of $TNF-{\alpha}$,IL-2, and IL-4 and significant increases in the values of IL-10. However, there were no significant differences in progesterone, estradiol and IL-6. Conclusion : From the above results, Dohongsamul-tang showed the strengthening of immunological function and anti-inflammatory effect. Therefore it is considered that Dohongsamul-tang will be very effective on the treatment of inflammation developed endometriosis, especially to treat the endometriosis without affecting the ovary functions.

Although several methods have been developed and applied to control swine respiratory diseases, the disease induces severe economic impact to swine industry worldwide. As one of the new trials, application of egg yolk antibody(IgY) was attempted for the purposes and immune response in sera and egg yolk was analysed with ELISA in previous study. In this study, immunological specificity of the IgY was analysed by Western blot analysis. In the analysis of causative agents of atrophic rhinits, B bronchiseptica and P multocida 4D, proteins of 33, 40, 43, 67 and 141 kDa were specifically reacted with IgY Also, 40 and 110 kDa proteins were identified as the major immunogens in P multocida 3A. In A pleuropneumoniae serotypes 2 and 5, 40 kDa and 47 kDa proteins were found to be the major reactive ones. These results suggested that egg yolk antibodies from immunized hens was specific with antigens injected into hens and partially purified antigens, outer membrane proteins and dermonecrotic toxin, were more effective than bacterin for the production of specific antibody.
