This study investigated the effects of vitamin C supplementation on immune status in smoking and nonsmoking male college students. Blood samples were obtained from 15 healthy smoking and from 15 healthy nonsmoking volunteers before and 4 weeks after vitamin C supplementation (1000mg/day). Daily nutrient intakes was also calculated. Plasma vitamin C, E, and A concentrations, white blood cells and subpopulations, lymphocytes and subpopulations, NK cell percentage,plasma immunoglobulin A, G, M and complement C3, plasma interleukin-2 , and prostagladin E2 were measured . Daily vitamin C consumption was lower in smokers than in nonsmokers. Vitamin C supplementation significantly increased plasma vitamin C in smokers, and increased NK cell percentage in smokers and nonsmokers. Plasma IL-2 concentrations were significantly increased by vitamin C supplementation in nonsmokers, and decreased helpe $r^pressor T cell ratio were decreased by vitamin C supplementatiion , but the differences were not significant. White blood cells and subpopulation percentage and plasma prostaglandin E2 concentration were not affected by smoking and vitamin C supplementation. These findings as nonsmokers.rs.

We have employed a DNA-native-polyacrylamide gel electrophoresis (DNA-native-PAGE) assay system to characterize the enzyme activity of the endonuclease secreted by human B lymphoblastic IM9 cells. Experimental results clearly demonstrated that the endonuclease activity of IM9 cell culture medium is distinct from that of DNase I in the DNA-native-PAGE assay system. Immunoprecipitation analysis using anti-DNase I antibody showed that the secreted endonuclease is not recognized by the antibody. The secreted endonuclease was estimated using supercoiled plasmid DNA as a substrate. The pH optimum required for the catalytic activity was determined to be in the range of pH 6.6-7.4. No significant difference in the endonuclease secretion was observed by stimulation of the IM9 cells with interferon-${\gamma}$ or interleukin-$1{\beta}$.

The present study was performed to assess the worth of using the by products for seaweed (Eucheuma spinosum) ethanol production process (SEPPB) as broiler feeds. For this purpose, 225 broiler chicks (white mini broilers) were used as experimental animals. The control (Control group) was fed with the broiler feeds. 5% mixture (5% SEPPB group) was fed with a 5% SEPPB mixture feeds, and the 10% mixture (10% SEPPB group) was fed with a 10% SEPPB group mixture feeds. The experiment was repeated for five times and 15 birds were assigned in each experiment and the experimental period was five weeks. There was no difference in the rate of weight gain until the second week of the 5% SEPPB group and 10% SEPPB group. However, the weight gain rate was increased to 6.2% for the 5% SEPPB group and 11.4% for the 10% SEPPB group as compared to the Control group at the third weeks of the experimental period. There was no statistical significant difference in terms of feed FCR and feed intake. Analyses of the quality of chicken breasts showed that pH was 2.5% higher in the 5% SEPPB group and 2.3% higher in the 10% SEPPB group. Shearing force was 31.3% lower in the 5% SEPPB group and 14.7% lower in the 10% SEPPB group, while heating loss was 14.4% lower for 5% SEPPB group and 10% SEPPB group when compared to the Control group. No significant differences were observed in terms of moisture, protein, and crude ash components in chicken breast analyses. However, crude fat was 36.8% higher in the 5% SEPPB group when compared to the Control group (P<0.05). Analyses of fatty acid in chicken breast meat showed that stearic acid was significantly higher in the 10% SEPPB group (P<0.05) and linolenic acid was significantly higher in 5% SEPPB group and 10% SEPPB group in comparison to the Control group (P<0.05). Interleukin-2 (IL-2) in blood serum was 44% higher in the 5% SEPPB group and 36% higher in the 10% SEPPB group (P<0.05). Interleukin-6 (IL-6) was similar in both the Control and the 5% SEPPB group, but it was 62% higher in the 10% SEPPB group in comparison to the Control group (P<0.05). Analyses of serum chemical values revealed that albumin was the highest in the 5% SEPPB group, followed by the Control group and then 10% SEPPB group.

In the progression of the Temporomandibular Joint Disorder(TMD), not only deformation and perforation of disc occur. But also fibrotic adhesion and inflammatory changes to the retrodiscal tissue can be seen in addition to the condylar degenerative change (e.g. osteoarthritis). However, the correct diagnosis,?planning for appropriate treatment, and prediction of prognosis are limited, because there are no means to stage the progression of the disorder. In this study relative signal intensity of retrodiscal tissue in MRI and the synovial fluid concentration of matrix metalloproteinase-2 (MMP-2), MMP-9, and Interleukin-6(IL-6) in the 23 temporomandibular joints(TMJ), from 17 patients with TMD were evaluated as a possible diagnostic marker. The relative signal intensity of retrodiscal tissue was referenced to brain gray matter with same region of interest(ROI) size. The concentrations of MMP-2, MMP-9, and IL-6 were evaluated by Enzyme Linked Immunosorbent Assay (ELISA). The collected data were compared with condylar degenerative change, joint effusion and disc position observed in MRI. The relative signal intensity of the retrodiscal tissue was increased significantly when degenerative changes were present. In addition, there was significantly high signal intensity in the presence of a disc displaced without reduction. The concentration of IL-6 was significantly increased when condylar degenerative change was no observed. And there were no changes in the levels of IL-6 according to disc position and joint effusion measurement. Moreover, there were no significant relevance between the concentration of total MMP-2 and active MMP-9 in synovial fluid, relative to degenerative changes in the mandibular condyle, to joint effusion, and to disc position observed on MRI images. In conclusion, the relative signal intensity of the retrodiscal tissue can be regarded as a mean of diagnosing the procession of TMD in a non-invasive manner. But more additional studies are required for the levels of MMP-2. MMP-9, and IL-6 to determine their potentials as a diagnostic marker for TMD.

Objective: The use of genetic markers can help to enhance reproduction in cattle, which is a very important trait for profitability in dairy production systems. This study evaluated the association between genotypes of leptin (LEP), toll-like receptor 4 (TLR4), and chemokine receptor of interleukin 8 C-X-C motif (CXCR1) genes and fertility traits in Czech Fleckvieh cattle. Methods: Phenotypic data from 786 Czech Fleckvieh cows raised on 5 farms in the Czech Republic were used, along with information from the 1st three parities. To determine genotype, the polymerase chain reaction-restriction fragment length polymorphism method was used. Results: Except for LEP g.-963C>T, all studied genotype frequencies of single nucleotide polymorphisms (SNPs) were distributed according to the Hardy-Weinberg equilibrium. Two LEP SNPs (g.-963C>T and c.357C>T) were associated with the age at the 1st calving, days open (DO), pregnancy rate after 1st service (PR), and calving interval (CLI). In LEP g.-963C>T the TT genotype heifers firstly calved 24 days earlier than CC genotype and the CT genotype cow showed a tendency for shorter DO and higher PR. In LEP c.357C>T we observed longer CLI and DO period in TT cows. In general, we can propose the TT genotype of g.-963C>T as favorable and the TT genotype of c.357C>T as unfavorable for a cow's fertility. Heterozygotes in TLR4 c.-226C>G were significantly associated with shorter CLI, and presented a nonsignificant tendency to be associated with higher PR. In CXCR1 c.777 C>G, we did not observe any relationship of this SNP with reproduction. Conclusion: Overall, the results showed that LEP could be an effective marker for improving reproduction in Czech Fleckvieh cattle. This study also provides novel insights into the relationship between TLR4 and CXCR1 SNPs and reproduction in dual-purpose cattle.

Interleukin-1${\beta}$ $(IL-1{\beta})$ is one of the key proinflammatory cytokines and it plays an important role for the antimycobacterial host defense mechanisms. In this study, we examined Mycobacterium tuberculosis (MTB)-stimulated induction of IL-1${\beta}$ and evaluated the associated signal transduction pathways. In PMA-differentiated THP-1 cells, MTB infection increased mRNA expression of IL-$1{\beta}$ in a dose-dependent manner. The expression of IL-1${\beta}$ mRNA began to be induced at 1.5 h after infection, and induced expression of IL-1${\beta}$ was retained for 48 h after MTB infection. The increase in expression of IL-1${\beta}$ caused by MTB was reduced in cells treated with Ro-31-8425 (an inhibitor of PK$C{\alpha}$, ${\beta}I$, ${\beta}II$, ${\gamma}$, ${\varepsilon}$) or PD98059 (an inhibitor of MEK1), meanwhile, pre-treatment with $G\ddot{o}6976$ (an inhibitor of $Ca^{2+}$ dependent PK$C{\alpha}$ and PK$C{\beta}I$) or Rottlerin (an inhibitor of PK$C{\delta}$) has no effect on MTB-induced expression of $IL-1{\beta}$ mRNA. These results show that the expression of $IL-1{\beta}$ mRNA caused by MTB may be mediated via MEK1 and PKC isoforms including PK$C{\beta}II$, $PKC{\gamma}$, or $PKC{\varepsilon}$. Further studies are required to determine whether other PKC isoforms $(PKC {\eta},\;{\theta},\;{\varepsilon},\;and\;{\lambda}/{\iota})$, except $PKC{\delta}$, $PKC{\alpha}$, and $PKC{\beta}I$, are also involved in $IL-1{\beta}$ mRNA expression after mycobacterial infection.

Breast cancer is the most frequent type of cancer diagnosed among women worldwide and also in Thailand. Estrogen and estrogen receptors exert important roles in its genesis and progression. Several cytokines have been reported to be involved in the microenvironment that promotes distant metastasis via modulation of immune and inflammatory responses to tumor cells. Estrogen receptor genetic polymorphisms and several cytokines have been reported to be associated with breast cancer susceptibility and aggressiveness. To investigate roles of genetic polymorphisms in estrogen receptor alpha (ESR1) and interleukin 6 (IL6), breast cancer patients and control subjects were recruited from the Division of Head, Neck and Breast Surgery (Siriraj Hospital, Bangkok, Thailand). Polymorphisms in ESR1 (rs3798577) and IL6 (rs1800795 and rs1800797) were evaluated by real-time PCR in 391 breast cancer patients and 79 healthy controls. Associations between genetic polymorphisms and clinicopathological data were determined. There was no association between genetic polymorphisms and breast cancer susceptibility. However the ESR1 rs3798577 CT genotype was associated with presence of lymphovascular invasion (OR=2.07, 95%CI 1.20-3.56, p=0.009) when compared to the TT genotype. IL6 rs1800795 CC genotype was associated with presence of extranodal extension (OR= 2.30, 95%CI 1.23-4.31, p=0.009) when compared to the GG genotype. Survival analysis showed that IL6 rs1800797 AG or AA genotypes were associated with lower disease-free survival. These findings indicate that polymorphisms in ESR1 and IL6 contribute to aggressiveness of breast cancer and may be used to identify high risk patients.

Objectives: The purpose of this study is to determine the stimulatory effects of herbal medicines extracts on cytokines release of immune response in immune cells, RAW 264.7 and TK-1 cell. Methods: In a total of 18 extracts, 9 water extracts and 9 ethanol extracts, of herbal medicines, the quantities of polyphenolic compounds were measured and anti-oxidation activities were determined by colorimetric assay. The herbal medicine extracts were treated on RAW 264.7 and TK-1, respectively, and then the releasing changes of tumor necrosis factor-${\alpha}$ ($TNF-{\alpha}$), interleukin-6, and interleukin-10 from both immune cells were determined by the enzyme-linked immunosorbent assay. Results: The polyphenol contents were measured to be 1.56~0.64 mg/g of solids in the two types of extracts with 9 kinds of herbal medicines, while antioxidant activities were found to be 95.62~31.46% as compared with ascorbic acid control. In RAW 264.7 cells treated with herbal medicines extracts, the secretion of $TNF-{\alpha}$ increased to 1.31~1.18 fold, and the amounts of IL-6 were 68.4~97.9% compared with the control group treated with LPS alone. In particular, the secretion amount of anti-inflammatory cytokine IL-10 was suppressed by treatment using herbal medicine extracts. In the case of TK-1 cells, $TNF-{\alpha}$ secretion was suppressed according to the concentrations of herbal extract. The released amounts of IL-10 were shown at 10~40 pg/ml, and increased in a dose-dependent manner. Conclusions: Herbal medicines extracts act on macrophages inducing the secretion of inflammatory cytokine, thereby enhancing the activity of innate immunity. When acting on T cells involved in adaptive immunity, the secretion of anti-inflammatory cytokine is increased to induce the inhibition of the innate immune response.

The aim of this research was to investigate the possible association between gastric carcinoma (GC) and polymorphisms of the IL-$1{\beta}$ gene in the Kashmiri population using peripheral blood DNA from 150 gastric carcinoma cases and 250 population controls with detailed data for clinicopathological characteristics of the disease. Two SNPs in the IL-$1{\beta}$ gene were selected for this study. Expression of IL-$1{\beta}$ was studied in 50 gastric carcinoma cases using immunohistochemistry and RT-PCR and then correlated with genotype. The frequency of the IL-$1{\beta}$-511 C allele was significantly higher in the GC case group (53.3%) than in controls (45.4%) with an odds ratio (OR) of 0.73 and a P value of 0.03. Multivariate regression analysis showed associations of gastric carcinoma with mutant form of IL-$1{\beta}$-511 TT (OR 0.309; P value <0.001) and the CC genotype of IL-$1{\beta}$-31 (OR 0.313; P value of 0.002). Haplotype analysis of IL-$1{\beta}$-31 and IL-$1{\beta}$-511 showed decreased association of IL-$1{\beta}$-31 T with IL-$1{\beta}$-511 C with gastric carcinoma (OR 0.728; P value 0.03). Expression study of 50 samples by immunohistochemistry (IHC) and RT-PCR showed association with grade III and stage III+IV. After correlating the expression with polymorphism no association was found.
