High-intensive endurance exercises induce cell changes in body, changes in structures and functions of the heart, the muscles, the cartilages, and the liver, as well as increase of inflammatory cytokine. The purpose of this study was to estimate the biochemical changes in the liver and muscles during ultra-marathon race (100 km) by sections. The blood of the subjects was collected before the marathon as a control in order to analyze serum creatine kinase (CK), lactic dehydrogenase (LDH), asprtate aminotransferase (AST), alanine aminotransferase (ALT), total(T)-bilirubin, direct(D)-bilirubin, total protein, albumin, uric acid, gamma-glutamyltranspeptidase (${\gamma}$-GTP), alkaline phosphatase (ALP), creatinine, blood urea nitrogen (BUN), and high sensitive C-reactive protein (hs-CRP) concentrations. The CK, LDH, D-bilirubin, AST and ALT concentrations at 50 km and 100 km were significantly increased compared to the control (P<0.05). The markers at 100 km were higher than those at 50 km (P<0.05). The T-bilirubin and hs-CRP concentrations showed no difference among the groups, whereas the markers at 100 km were higher than those of the control and at 50 km (P<0.05). In conclusion, this study shows that the ultra-marathon race (100 km) may induce the damage of the skeletal muscle, liver and kidney, intravascular hemolysis and inflammatory responses.

Tumor necrosis facto-related apoptosis-inducing ligand (TRAIL) is a recently identified member of the tumor necrosis factor cytokine superfamily. TRAIL has been shown to induce apoptosis in a number of tumor cells whereas cells from most of normal tissues are highly resistant to TRAIL-induced apoptosis. These observations have raised considerable interest in the use of TRAIL in tumor therapy. In this study we report the biodistribution fates and serum expression pattern of plasmid DNA encoding TRAIL (pTRAIL) delivered in erythrocyte ghosts (EG). pTRAIL was loaded into EG by electroportion in a hypotonic medium The mRNA expression of pTRAIL was prolonged following delivery in EG-encapsulated forms. EG containing pTRAIL showed significant levels of mRNA expression in the blood over 9 days. The organ expression patterns of pTRAIL delivered via EG, however, did not significantly differ from those of naked pTRAIL, indicating that the expression-enhancing effect of EG containing pTRAIL was localized to the blood. These results suggest that pTRAIL-loaded EG might be of potential use in the treatment of hematological diseases such as TRAIL-sensitive leukemia.

Purpose : Salviae Miltiorrhizae Radix is a herb with an effect on extravasated blood and is widely used in gynecology. This study examine, the effects of Salviae Miltiorrhizae Radix on endometriosis. Methods : Rats with surgically induced endometriosis were administered Salviae Miltiorrhizae Radix for 40 days. The size of the ectopic uterine implants at the serosal wall and the concentration of progesterone, estradiol, TNF-${\alpha}$ and IL-2, 4, 6 and 10 in the blood were examined and compared with the control group. Results : The size of the ectopic uterine implants in the treated group was much smaller than that in the control group. The estradiol concentration was significantly lower in the experimental group than in the control group. The IL-10 level was significantly higher in the experimental group than in the control group. The TNF-${\alpha}$ level was lower in the experimental group than in the control group but the difference was not significant. The progesterone, IL-2, 4, 6 levels were similar in the experimental and control groups. Conclusion : These results indicate that Salviae Miltiorrhizae Radix reduces the size of ectopic uterine implants at the serosal wall and inhibits the growth of ectopic uterine implants. This suggests that Salviae Miltiorrhizae Radix is an effective treatment for endometriosis.

To investigate the effect of fluoxetine, one of selective serotonin reuptake inhibitors (SSRIs), on the immune system, human peripheral blood mononuclear cells (PBMC) were treated with fluoxetine $(10^{-7}\;M)$ for 24 h, and immune-related genes were analyzed by cDNA microarray. Expression of the immunerelated genes such as CD107b (LAMP-2), CD47 receptor (thrombospondin receptor), CD5 antigen-like (scavenger receptor cysteine rich family), copine III (CPNE3), interleukin (IL)-18 (interferon-gammainducing factor), integrin alpha 4 (CD49d), integrin alpha L subunit (CD11a), IL-3 receptor alpha subunit, L apoferritin, and small inducible cytokine subfamily A (Cys-Cys) member 13 (SCYA13) was induced by fluoxetine. This result suggests that fluoxetine may affect the immune system, and provides fundamental data for the involvement of SSRIs on immunoregulation.

Alzheimer's disease (AD) is a chronic neurodegenerative disease characterized by the accumulation of amyloid plaques and neurofibrillary tangles in the brain. The AD pathophysiology entails chronic inflammation involving innate immune cells including microglia, astrocytes, and other peripheral blood cells. Inflammatory mediators such as cytokines and complements are also linked to AD pathogenesis. Despite increasing evidence supporting the association between abnormal inflammation and AD, no well-established inflammatory biomarkers are currently available for AD. Since many reports have shown that abnormal inflammation precedes the outbreak of the disease, non-invasive and readily available peripheral inflammatory biomarkers should be considered as possible biomarkers for early diagnosis of AD. In this minireview, we introduce the peripheral biomarker candidates related to abnormal inflammation in AD and discuss their possible molecular mechanisms. Furthermore, we also summarize the current state of inflammatory biomarker research in clinical practice and molecular diagnostics. We believe this review will provide new insights into biomarker candidates for the early diagnosis of AD with systemic relevance to inflammation during AD pathogenesis.

Ancylostoma ceylanicum is a zoonotic soil-derived nematode that parasitizes the intestines of humans and animals (dogs and cats), leading to malnutrition and iron-deficiency anemia. Helminth parasites secrete calreticulin (CRT), which regulates or blocks the host's immune response. However, no data on A. ceylanicum calreticulin (Ace-CRT) are available. We investigated the biological function of recombinant Ace-CRT (rAce-CRT). rAce-CRT showed reliable antigenicity and stimulated the proliferation of mouse splenocytes and canine peripheral blood mononuclear cells. Quantitative reverse-transcription PCR assays revealed that rAce-CRT primarily promoted the expression of T helper 2 cytokines, particularly IL-13, in canine peripheral blood lymphocytes. rAce-CRT inhibited complement-mediated sheep erythrocyte hemolysis in vitro. Our findings indicate that Ace-CRT plays an immunomodulatory role and may be a promising candidate molecule for a hookworm vaccine.

The morphological characteristics of newly isolated Cordyceps hepialidicola were characterized, and the phylogenetic relationships with other Cordyceps species were investigated using a sequence analysis of the internal transcribed spacer (ITS). The PCR product of 592 bp showed a homology of 92 and 91% with C. militaris and C. nutans, respectively, In an in vitro model using mouse peripheral blood mononuclear cells (PBMC), a methanol extract of C. hepialidicola induced multiple cytokines, including IFN-${\gamma}$ IL-4, and IL-18. The extract also enhanced the percentages of the CD4$\^$+/ and CD8$\sub$+/ T cells in the healthy murine PBMCs to 56.1% and 13.0%,respectively. The percentages of CD4$\^$+/ and CD8$\^$+/ in the untreated controls were 28.4 and 7.3%, and concanavalin A-treated positive controls were 62.4 and 18.3%, respectively.

Amorphous silica particles, whose applications are increasing in many biomedical fields, are known to be less toxic than crystalline silica. In this study, the inflammatory effects of amorphous silica nanoparticles were investigated using 30-nm amorphous silica nanoparticles and human peripheral blood mononuclear cells (PBMCs) or purified monocytes. As a result, production of IL-$1{\beta}$ and IL-8 were increased. In addition, the mitochondrial reactive oxygen species (ROS) was detected, which may lead to mitochondrial membrane disruption. Most importantly, inflammasome formation was observed. Therefore, these results provide immunological information about amorphous silica nanoparticles and suggest that amorphous silica nanoparticles can evoke innate immune reactions in human monocytes through production of IL-$1{\beta}$ and IL-8.
