This study was peformed to evaluate antithrombotic activities and anti-inflammatory effects of Kami-BoyangHwanoh-Tang(KBHT). The major findings were summarized as follows. In experiment of anti-thrombotic effect; KBHT inhibited human platelet aggregation induced by ADP and epinephrine as compared with the control group and inhibited pulmonary embolism induced by collagen and epinephrine (inhibitory rate is 50 %). KBHT increased platelet number significantly and also KBHT shortened PT and APTT significantly as compared with the control group in thrombus model induced by dextran. In experiment of anti-inflammatory effect; KBHT inhibited $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, COX-2 and NOS-II mRNA expression as compared with the control group in a concentration-dependent degree, and inhibited NO production significantly at 50, $100\;{\mu}g/^{ml}$, and also inhibited ROS production in a concentration-dependent degree as compared with the control group in RAW 264.7 cell line. KBHT inhibited $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production significantly in serum of acute inflammation-induced mice, and decreased $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production in spleen tissue, and also decreased IL-6 and $TNF-{\alpha}$ production in liver tissue, but increased $IL-1{\beta}$ production in liver tissue of acute inflammation-induced mice. KBHT increased survival rate at 3rd day in mice with lethal endotoxemia induced by LPS. These results suggest that KBHT can be useful in treating diverse female diseases caused by thrombosis and inflammation such as endometrosis, myoma, pelvic congestion, chronic cervicitis, chronic pelvic inflammatory disease and so on.

Vibrio harveyi, one of the major causal agent of vibriosis, affects a diverse range of marine vertebrates and invertebrates over a wide geographical area. The aims of this study were to investigate the characteristics of extracellular products (ECPs) from an isolate of the pathogenic non‐luminous V. harveyi and the luminous V. harveyi. And ECPs of V. harveyi were examined the pathogenicity to the black rockfish, Sebastes schlegeli, and histopathological traits of internal organs injected by ECPs. Four strains of V. harveyi cultures produced ECPs showing various enzymatic activites (caseinase, gelatinase, phospholipase, lipase, haemolysin). The ECPs showed strong cytotoxicity on macrophages of black rockfish, Sebastes schlegeli and olive flounder, Paralichthys olivaceus. Especially, the virulence of ECPs from the isolate of V. harveyi FR 2 was higher in the intraperitoneally injected black rockfish. Also, the ECPs of V. harveyi FR 2 caused the expansion of sinusoids in the liver, the activation of ellipsoid in the spleen and the sloughing of the epidermal cell in the intestine. It was suggested that the ECPs from V. harveyi play an important role in the pathogenicity process of the V. harveyi.

The Interferon stimulated gene 15 (ISG15) is strongly induced in many cell types by IFNs, viral infections, and double-stranded RNA (poly I:C). The ISG15 homologue cDNA was isolated from the rock bream LPS stimulated leukocyte cDNA library. The rock bream ISG15 homologue was found to consist of 833 bp encoding 157 amino acid residues. Compared with other known ISG15 peptide sequences, the most conserved regions of the rock bream ISG15 peptide were found to be the tandem ubiquitin-like domains and a C-terminal LRLRGG conjugating motif, characteristic of mammalian and non-mammalian ISG15 proteins. Phylogenetic analysis based on the deduced amino acid sequence revealed a homologous relationship between the ISG15 sequence of rock bream and that of Atlantic salmon, Atlantic cod, northern snake head, black rockfish and olive flounder. The expression of the rock bream ISG15 molecule was induced in the peripheral blood leukocytes (PBLs) from 1 to 24 h following poly I:C stimulation, with a peak at 3 h post-stimulation. The rock bream ISG15 gene was predominantly expressed in the PBLs, spleen and gill.

BACKGROUND/OBJECTIVES: Oligonol, mainly found in lychee fruit, is an antioxidant polyphenolic compound which has been shown to have anti-inflammatory and anti-cancer properties. The detailed mechanisms by which oligonol may act as an anti-aging molecule have not been determined. MATERIALS/METHODS: In this study, we evaluated the ability of oligonol to modulate sirtuin (SIRT) expression in human lung epithelial (A549) cells. Oligonol was added to A549 cells and reactive oxygen species production, mitochondrial superoxide formation, and p21 protein levels were measured. Signaling pathways activated upon oligonol treatment were also determined by western blotting. Furthermore, the anti-aging effect of oligonol was evaluated ex vivo in mouse splenocytes and in vivo in Caenorhabditis elegans. RESULTS: Oligonol specifically induced the expression of SIRT1, whose activity is linked to gene expression, metabolic control, and healthy aging. In response to influenza virus infection of A549 cells, oligonol treatment significantly up-regulated SIRT1 expression and down-regulated viral hemagglutinin expression. Oligonol treatment also resulted in the activation of autophagy pathways and the phosphorylation of AMP-activated protein kinase (AMPK). Furthermore, oligonol-treated spleen lymphocytes from old mice showed increased cell proliferation, and mRNA levels of SIRT1 in the lungs of old mice were significantly lower than those in the lungs of young mice. Additionally, in vivo lethality assay revealed that oligonol extended the lifespan of C. elegans infected with lethal Vibrio cholerae. CONCLUSIONS: These data demonstrated that oligonol may act as an anti-aging molecule by modulating SIRT1/autophagy/AMPK pathways.

Purpose: This study was performed to evaluate anti-thrombotic and anti-inflammatory effects of NeungaSoJeokTang water extract (NSJT). Methods: In the study of anti-inflammatory effects, NSJT was investigated using cultured cells and murine models. As for the parameters of inflammation, levels of several inflammatory cytokines and chemical mediators which are known to be related to inflammation were determined in mouse lung fibroblast cells(mLFC) and RAW 264.7 cells. Results: Prior to the experiment, we evaluated sGOT, sGPT, BUN and creatine after the treatment. As a result, NSJT was innoxious on liver and kidney. In experiment of anti-thrombotic effect, NSJT inhibited the platelet aggregation induced by ADP and epinephrine, and inhibited pulmonary embolism induced by collagen and epinephrine. NSJT did not affect significantly the blood flow rate both in vitro and in vivo. NSJT increased platelet number and fibrinogen amount, and NSJT shortened PT and APTT in thrombus model induced by dextran. In experiment of anti-inflammatory effect, NSJT inhibited $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, COX-2 and NOS-II mRNA expression in a concentration-dependent manner in RAW 264.7 cell line, and inhibited significantly NO production at 50, 100 ${\mu}g/ml$, and also inhibited ROS production in a concentration-dependent manner. NSJT inhibited $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production significantly in serum of acute inflammation-induced Balb/c mice, and decreased $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production in spleen tissue, but increased $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production in liver tissue. NSJT increased survival rate at the 3th day in ICR mice with lethal endotoxemia induced by LPS. Conclusion: These results suggest that NSJT can be used for treating diverse female diseases caused by thrombosis and inflammation such as pelvic pain, pelvic inflammatory disease as well as vulvar pain due to vulvitis, vulvar vestibulitis and so on.

Background: Korean Red Ginseng (KRG) has been widely used as an herbal medicine to normalize and strengthen body functions. Although many researchers have focused on the biological effects of KRG, more studies on the action mechanism of red ginseng are still needed. Previously, we investigated the proteomic changes of the rat spleen while searching for molecular signatures and the action mechanism of KRG. The proteomic analysis revealed that differentially expressed proteins (DEPs) were involved in the increased immune response and phagocytosis. The aim of this study was to evaluate the biological activities of KRG, especially the immune-enhancing response of KRG. Methods: Rats were divided into 4 groups: 0 (control group), 500, 1000, and 2000 mg/kg administration of KRG powder for 6 weeks, respectively. Isobaric tags for relative and absolute quantitation was performed with Q-Exactive LC-MS/MS to compare associated proteins between the groups. The putative DEPs were identified by a current UniProt rat protein database search and by the Gene Ontology annotations. Results: The DEPs appear to increase the innate and acquired immunity as well as immune cell movement. These results suggest that KRG can stimulate immune responses. This analysis refined our targets of interest to include the potential functions of KRG. Furthermore, we validated the potential molecular targets of the functions, representatively LCN2, CRAMP, and HLA-DQB1, by Western blotting. Conclusion: These results may provide molecular signature candidates to elucidate the mechanisms of the immune response by KRG. Here, we demonstrate a strategy of tissue proteomics for the discovery of the molecular function of KRG.

Placenta specific 8 (PLAC8, also known as ONZIN) is a multi-functional protein that is highly expressed in the intestine, lung, spleen, and innate immune cells, and is involved in various diseases, including cancers, obesity, and innate immune deficiency. Here, we generated a Plac8 knockout mouse using the CRISPR/Cas9 system. The Cas9 mRNA and two single guide RNAs targeting a region near the translation start codon at Plac8 exon 2 were microinjected into mouse zygotes. This successfully eliminated the conventional translation start site, as confirmed by Sanger sequencing and PCR genotyping analysis. Unlike the previous Plac8 deficient models displaying increased adipose tissue and body weights, our male Plac8 knockout mice showed rather lower body weight than sex-matched littermate controls, though the only difference between these two mouse models is genetic context. Differently from the previously constructed embryonic stem cell-derived Plac8 knockout mouse that contains a neomycin resistance cassette, this knockout mouse model is free from a negative selection marker or other external insertions, which will be useful in future studies aimed at elucidating the multi-functional and physiological roles of PLAC8 in various diseases, without interference from exogenous foreign DNA.
