Brine mineral water (BMW) is groundwater near the deep sea, and the mineral component of the BMW is different from the water of the deep sea because the components of BMW are derived from the unique geographical features surrounding it. Recently, BMW has attracted attention due to the unique health-related minerals it possesses; however, the influence of BMW on physiological function has not yet been determined in domestic animals. Therefore, this experiment investigated the influence of BMW on the growth performance, water intake, blood properties, and immunoglobulin (Ig) levels of serum in growing-finishing pigs. A total of 64 pig barrows (Landrace × Yorkshire × Duroc) with an average initial weight of 40.56 ± 0.17 kg were used in the experiment, and 0%, 2%, 3%, and 5% samples of BMW diluted with freshwater were provided to experimental animals during the 56 days. We found that the gain/feed ratio in the 3% BMW group was significantly higher than that in the 5% BMW group of growing-finishing pigs (p < 0.05). The water intake was significantly increased in the 5% BMW group compared with the other groups (p < 0.05) of growing-finishing pigs. Additionally, the concentrations of red blood cells (RBCs), hemoglobin (HGB), and hematocrit (HCT) were significantly higher in the 3% BMW group than in the control group. The level of high-density lipoprotein cholesterol was higher in the 3% BMW group than in the 5% BMW group (p < 0.05). Furthermore, IgG and IgM levels in the serum were significantly higher in the 2% and 3% BMW groups than in the control group (p < 0.05). These results suggest that a dilution of 3% BMW in the intake water could improve the levels of RBCs and serum Igs in growing-finishing pigs.

Background: Immunoglobulin (Ig) light chain repertoire has been implicated as a critical determinant in regulation of autoreactive B cells and production of pathogenic anti-DNA antibodies in systemic lupus erythematosus (SLE). We analyzed the impact of Ig ${\lambda}$ chain repertoire on development of autoimmunity in patients with SLE. Methods: We obtained genomic DNA from individual peripheral CD19+ B cells of 3 untreated active SLE patients, and amplified $V{\lambda}$ rearrangements from each single cell by polymerase chain reaction. Results: A total number of 208 $V{\lambda}J{\lambda}$ rearrangements were analyzed. Analyzed sequences included 158 productive rearrangements and 50 nonproductive rearrangements. The differences in $V{\lambda}$ gene usage in the productive and nonproductive repertoire of SLE patients were found compared to the non-autoimmune individuals. $V{\lambda}$ gene, 9A was significantly overrepresented in nonproducative repertoire of SLE patients (P=0.016). In the productive repertoire, $V{\lambda}$ genes, 3L and 1E were found more often in the SLE patients (P=0.001, P=0.043). When the productive and the nonproductive repertoires were compared, 9A was found significantly less in the productive repertoire in the SLE patients (P=0.000). There were no significant differences in the $J{\lambda}$ gene usage between SLE patients and non-autoimmune individuals, but $J{\lambda}2/3$ gene was the most frequently used in SLE, whereas $J{\lambda}7$ gene was the most frequently used in the normal subjects. In the productive SLE $V{\lambda}$ repertoire, 9.4% of the total sequences employed identical CDR3. It was particularly striking to find 7 identical versions of the 1G-$J{\lambda}2/3$ $V{\lambda}J{\lambda}$ rearrangements from one patient and 3 of the same sequence from another patient. Notably, identical $V{\lambda}$ junctions in the SLE patients utilized significantly more homologous joining compared to $V{\lambda}$ junctions of the normal adults (P=0.044). Conclusion: These data demonstrate regulation of ${\lambda}$ light chain expression in the SLE patients by selection of unique $V{\lambda}$ genes. Also, biased selection and clonal expansion of particular $V{\lambda}$ rearrangements are apparent in the SLE ${\lambda}$ repertoire.

Purpose: This study was conducted to investigate the immune responses of children with moderate and severe novel influenza A virus (H1N1) pneumonia, and to compare their clinical and immunological findings with those of control subjects. Methods: Thirty-two admitted patients with H1N1 pneumonia were enrolled in the study. The clinical profiles, humoral and cell-mediated immune responses of the 16 H1N1 pneumonia patients who were admitted to the pediatric intensive care unit (severe pneumonia group), 16 H1N1 pneumonia patients admitted to the pediatric general ward (moderate pneumonia group) and 13 control subjects (control group) were measured. Results: Total lymphocyte counts were significantly lower in patients with H1N1 pneumonia than in the control group (P=0.02). The number of CD4+ T lymphocytes was significantly lower in the severe pneumonia group ($411.5{\pm}253.5/{\mu}L$) than in the moderate pneumonia ($644.9{\pm}291.1/{\mu}L$, P=0.04) and control ($902.5{\pm}461.2/{\mu}L$, P=0.01) groups. However, the number of CD8+ T lymphocytes was significantly higher in the severe pneumonia group ($684.2{\pm}420.8/{\mu}L$) than in the moderate pneumonia ($319.7{\pm}176.6/{\mu}L$, P=0.02) and control ($407.2{\pm}309.3/{\mu}L$, P=0.03) groups. The CD4+/CD8+ T lymphocytes ratio was significantly lower in the severe pneumonia group ($0.86{\pm}0.24$) than in the moderate pneumonia ($1.57{\pm}0.41$, P=0.01) and control ($1.61{\pm}0.49$, P=0.01) groups. The serum levels of immunoglobulin G, immunoglobulin M and immunoglobulin E were significantly higher in the severe pneumonia group than in the 2 other groups. Conclusion: The results of this study suggest that increased humoral immune responses and the differences in the CD4+ and CD8+ T lymphocyte profiles, and imbalance of their ratios may be related to the severity of H1N1 pneumonia in children.

The antagonistic activities against animal entero-pathogenic bacteria were investigated with 444 natural substances fermented by various probiotics. A white rice product fermented (FWR) by Clostridium butyricum IDCC 9207 with a high growth inhibition of Salmonella typhimurium KCTC 2054 and Escherichia coli O157:H7 was selected. Also, a FWR was shown to suppress 8 among 21 pathogenic bacteria. In a mouse model with salmonella (${\times}10^9$ CFU/mouse) infection, 5 samples (200 ${\mu}{\ell}$/mouse/day) were fed to mice (n = 25) for 18 days. A fermented white rice containing C. butyricum IDCC 9207 (FWRCb9207) among 5 samples significantly inhibited the growth of salmonella, while in the control group (PBS, tetracycline) the number of salmonella increased. And the treatment with FWRCb9207 was found to increase the secretory immunoglobulin A (sIgA) level in the feces of salmonella-infected mice. The results obtained in this study suggest that a FWRCb9207 might be utilized as a feed additive in pigs and poultry diets.

Purpose: T-cell immunoglobulin and mucin domain-containing molecule 3 (TIM-3) is an emerging immune response molecule related to T-cell anergy. There has been tremendous interest in breast cancer targeting immune checkpoint molecules, especially in the triple-negative breast cancer (TNBC). This study was designed to investigate TIM-3 expression on tumor infiltrating lymphocytes (TILs), its relationships with clinicopathological parameters and expression of programmed death receptor 1 (PD-1)/programmed death receptor ligand 1 (PD-L1), and its prognostic role. Methods: Immunohistochemistry on tissue microarray blocks produced from 109 samples of invasive ductal carcinoma type TNBC was performed with antibodies toward TIM-3, PD-1, PD-L1 and breast cancer-related molecular markers. Associations between their expression and clinicopathological parameters as well as survival analyses were performed. Results: TIM-3 was expressed in TILs from all 109 TNBCs, consisting of 17 cases (<5%), 31 cases (6%-25%), 48 cases (26%-50%), and 13 cases (>51%). High TIM-3 was significantly correlated with younger patients (p=0.0101), high TILs (p=0.0029), high tumor stage (p=0.0018), high PD-1 (p=0.0001) and high PD-L1 (p=0.0019), and tended to be associated with higher histologic grade, absence of extensive in situ components and microcalcification. High TIM-3 expression was significantly associated with a combinational immunophenotype group of high PD-L1 and high PD-1 (p<0.0001). High TIM-3 demonstrated a significantly better disease-free survival (DFS) (p<0.0001) and longer overall survival (OS) (p=0.0001), together with high TILs and high PD-1. In univariate survival analysis, high TIM-3 showed reduced relapse risk (p<0.0001) and longer OS (p=0.0003), together with high PD-1 expression. In multivariate analysis, high TIM-3 was statistically significant in predicting prognosis, showing better DFS (hazard ratio [HR], 0.0994; 95% confidence interval [CI], 0.0296-0.3337; p=0.0002) and longer OS (HR, 0.1109; 95% CI, 0.0314-0.3912; p=0.0006). Conclusion: In this study, we demonstrate that TIM-3 expression is an independent positive prognostic factor in TNBC, despite its association with poor clinical and pathologic features.

This study was conducted to investigate the effects of dietary quercetin on growth performance, blood biochemical parameters, immunoglobulin, and blood antioxidant activity in broiler chickens. Three hundred twenty one-day old Ross broilers were divided 8 treatments (C(-), basal diet; C(+), basal diet with antibiotics; vitamin E 20 IU; vitamin E 200 IU; quercetin 20 ppm; quercetin 200 ppm; methoxylated quercetin 20 ppm; methoxylated quercetin 200 ppm) with 4 replicates and 10 birds per replicate. Birds were reared for 35 days and their feed intake and weight gain were measured weekly. At 35d, eight birds of average weight from each replicate were selected for blood collection and analysis. Weight gain of birds in the groups fed quercetin was higher when compare to NC but there was no significant difference. In the serum, creatinine, BUN and AST in quercetin groups significantly decreased compared to those of control (NC and PC) (P<0.05). The contents of IgA and IgM were significantly lower in quercetin groups than those of NC (P<0.05). SOD like activity and MDA content tended to decrease in quercetin groups, however, there was no significant difference among treatments. In conclusion, supplemental quercetin to poultry diet could be positive aspect on performance and blood metabolites. Optimum adding levels was more than 20 ppm.

Guillain-$Barr{\acute{e}}$ syndrome and acute transverse myelitis manifest as demyelinating diseases of the peripheral and central nervous system. Concurrency of these two disorders is rarely documented in literature. A 4-year-old girl presenting with cough, fever, and an impaired walking ability was admitted to hospital. She had no previous complaints in her medical history. A physical examination revealed lack of muscle strength of the lower extremities and deep tendon reflexes. MRI could not be carried out due to technical problems; therefore, both Guillain-$Barr{\acute{e}}$ syndrome and acute transverse myelitis were considered for the diagnosis. Intravenous immunoglobulin treatment was started as first line therapy. Because this treatment did not relieve the patient's symptoms, spinal MRI was carried out on the fourth day of admission and demyelinating areas were identified. Based on the new findings, the patient was diagnosed with acute transverse myelitis, and high dose intravenous methylprednisolone therapy was started. Electromyography findings were consistent with acute polyneuropathy affecting both motor and sensory fibers. Therefore, the patient was diagnosed with concurrency of Guillain-$Barr{\acute{e}}$ syndrome and acute transverse myelitis. Interestingly, while concurrency of these 2 disorders is rare, this association has been demonstrated in various recent publications. Progress in diagnostic tests (magnetic resonance imaging and electrophysiological examination studies) has enabled clinicians to establish the right diagnosis. The possibility of concurrent Guillain-$Barr{\acute{e}}$ syndrome and acute transverse myelitis should be considered if recovery takes longer than anticipated.

House dust mites (HDMs) play an important role in the occurrence of allergic diseases such as asthma and atopic dermatitis. Dermatophagoides pteronyssinus (Der p) is one of the most prevalent HDMs. It mediates the activation of T cells and monocytes, and induces the elevation of immunoglobulin E levels in allergic diseases. However, the effects of Der p on human monocytes have not been fully understood. In the present study, we investigated whether or not Der p has a great effect on the chemotactic activity of the human monocytic cell line, THP-1 cells, as induced by CC chemokines. We also show that the Der p extract (DpE) increased the chemotactic activity of THP-1 cells in response to MCP-1, RANTES, MIP-1${\alpha}$, and TARC, but had no effect on the expressions of CC chemokine receptors (CCRs) binding to CC chemokines in THP-1 cells. Protease inhibitors, such as aprotinin and E64, blocked the increased chemotaxis, while cytoplasmic $Ca^{2+}$ influx mediated by these chemokines was inhibited by DpE. These results indicate that DpE increases the chemotactic activity of THP-1 cells in response to CC chemokines by regulating the cells' protease-dependent mechanism. This finding may be useful in identifying the pathogenesis of allergic diseases induced by Der p.

Purpose: Celiac disease (CD) is an autoimmune disorder of the small intestine caused by an abnormal immune response to gluten proteins and is often characterized by gastrointestinal symptoms. Food allergy (FA) is an adverse immune sensitivity to ingested food proteins leading to inflammation in various organs including the gastrointestinal tract. The relationship between CD and FA remains unclear. This study aimed to assess the prevalence and clinical relevance of immunoglobulin E (IgE)-mediated food sensitization in children with CD. Methods: Fifty-nine children diagnosed with CD were reviewed for clinical symptoms and evidence of IgE-sensitization to food and airborne allergens using the PolyCheck method. Results: IgE-mediated sensitization has been diagnosed in 20.3% of children with CD (CD/A). In the CD/A group, 58.3% of children were sensitized to food and 66.7% to airborne allergens. Further, 41.7% of patients with CD and allergy reported gastrointestinal tract symptoms associated with the ingestion of sensitizing foods. Analysis of the clinical status revealed that the incidence of other allergic disorders in the CD/A group was as follows: atopic dermatitis (33.3%), asthma (25.0%), and allergic rhinitis (16.7%). The percentage of eosinophils was significantly higher in the CD/A group than in the CD group (0.33±0.25 vs. 0.11±0.09; p=0.006). Conclusion: The diagnosis of CD does not exclude FA. The gastrointestinal symptoms in children with CD may be the result of both CD and FA; therefore, children with CD should be evaluated for the presence of FA regardless of age.

The efficacies of anti-atopic preparations were investigated in hairless mice suffering from 2,4-dinitro-chlorobenzene (DNCB)-induced atopic dermatitis-like lesion. Solid lipid nanoparticle (SLN) containing ceramide and astaxanthin was prepared by a melt-homogenization method using Aminsoft-CT 12 (Cocoyl glutamate) as an emulsifier. And then, the SLNs were coated with silk fibroin (SF) by taking advantage of an electrostatic interaction between the surface of SLNs and SF. SLNs were included in lotion (FL) and cream (FC) types of preparations. Anti-atopic efficacies of the preparations were investigated in terms of appearance of skin surface, spleen index, serum IgE level, and serum cytokine level. SLN-containing preparations suppressed IgE production and IL-4 expression, but promoted $IFN-{\gamma}$ expression.
