Complex microbial communities play an important role in the human health and co-evolved with human in the form of symbiosis. Many literatures provide new evidences that the increased prevalence of obesity cannot be attributed solely to changes in the human genome, nutritional habits, or reduction of physical activity in our daily lives. The intestinal flora was recently proposed as an environmental factor responsible for the control of body weight and energy metabolism. A number of studies suggest that the modulation of gut microbiota affects host metabolism and has an impact on energy storage and demonstrated a role for the gut microbiota in weight gain, fat increase, and insulin resistance. Variations in microbiota composition are found in obese humans and mice and the microbiota from an obese mouse confers an obese phenotype when transferred to an axenic mouse. As well, the gut microbial flora plays a role in converting nutrients into calories. Specific strategies for modifying gut microbiota may be a useful means to treat or prevent obesity. Dietary modulations of gut microbiota with a view to increasing bifidobacteria have demonstrated to reduce endotoxemia and improve metabolic diseases such as obesity. The fermentation of medicinal herbs is intended to exert a favorable influence on digestability, bioavailability and pharmacological activity of herbal extract. Therefore we also expect that the fermented herbal extracts may open up a new area to treat obesity through modulating gut microbiota.

Purpose : This study was performed to evaluate anti-thrombotic and anti-inflammatory effects of BokbangHongdeungPaejangSan water extract (BHPS). Methods : BHPS was investigated using cultured cells and a 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 : In experiment of anti-thrombotic effect, BHPS inhibited the platelet aggregation induced by ADP and epinephrine, and inhibited pulmonary embolism induced by collagen and epinephrine. BHPS increased Platelet number and fibrinogen amount, and shortened PT and APTT in thrombus model induced by dextran. In experiment of anti-inflammatory effect, BHPS 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. BHPS 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. BHPS increased survival rate at the 3th day in ICR mice with lethal endotoxemia induced by LPS. Conclusion : These results suggest that BHPS can be used for treating diverse female diseases caused by thrombosis and inflammation such as endometriosis, pelvic pain, cervicitis, pelvic inflammatory disease and pelvic tuberculosis and so forth.

A $2{\times}3$ factorial arrangement of treatments was used in a completely randomized design to determine the effects of dietary Zn on performance and immune response of acutely endotoxemic growing pigs (n=96, mean BW=24.9 kg). Factors included 1) intramuscular injection of $10{\mu}g/kg$ BW of Escherichia coli lipopolysaccharide (LPS) or control and 2) supplemental Zn at 10, 50, or 150 ppm. Diets were fed beginning after weaning (initial body weight=7.6 kg) in the nursery and continued for 16 d into the grower phase. The basal corn-soybean meal grower diet contained 1% lysine and 34.3 ppm Zn. Pigs were acclimated for 12 d in the growerfinishing facility before LPS treatment on d 13. Gain, feed intake, and feed efficiency were unaffected by dietary Zn. Feed intake decreased (p<0.10) and gain/feed was greater (p<0.10) from d 13 to d 16 for pigs injected with LPS. Serum Zn and alkaline phosphatase activity increased (p<0.05) with increasing Zn levels. The febrile response to LPS peaked at 6 h post exposure and pigs were afebrile within 12 h. Rectal temperature was greater (p<0.05) in pigs receiving 50 and 150 ppm Zn than in pigs supplemented with 10 ppm Zn. In vivo cellular immune response, measured on d 13 by skin thickness response to phytohemagglutinin (PHA), was greater after 6 h (p<0.05) in pigs fed 10 ppm Zn and exposed to LPS compared to all other treatments, but was not affected at 12, 24 or 48 h. Zinc did not affect mitogen induced lymphocyte proliferation. Zinc supplemented at 50 or 150 ppm resulted in an enhanced febrile response in pigs subjected to iatrogenic endotoxemia, but did not affect pig performance or immune response measurements.

In the previous studies, we isolated the compound K rich fractions (CKRF) and showed that CKRF inhibited Toll-like receptor (TLR) 4- or TLR9-induced inflammatory signaling. To extend our previous studies,1) we investigated the molecular mechanisms of CKRF in the TLR4-associated signaling via nuclear factor (NF)-${\kappa}B$, and in vivo role of CKRF for induction of tolerance in lipopolysaccharide (LPS)-induced septic shock. In murine bone marrow-dervied macrophages, CKRF significantly inhibited the induction of mRNA expression of proinflammatory mediators such as tumor necrosis factor-${\alpha}$, interleukin-6, cyclooxygenase-2, and inducible nitric oxide synthase. In addition, CKRF significantly attenuated the transcriptional activities of TLR4/LPS-induced NF-${\kappa}B$. Nuclear translocation of NF-${\kappa}B$ in response to LPS stimulation was significantly abrogated by pre-treatment with CKRF. Furthermore, CKRF inhibited the recruitment of p65 to the interferon-sensitive response element flanking region in response to LPS. Finally, oral administration of CKRF significantly protected mice from Gram-negative bacterial LPS-induced lethal shock and inhibited systemic inflammatory cytokine levels. Together, these results demonstrate that CKRF modulates the TLR4-dependent NF-${\kappa}B$ activation, and suggest a therapeutic role for Gram-negative septic shock.

In the present study, the inhibitory effect of neem leaf extract (NLE) on lipopolysaccaride (LPS)-induced nitric oxide (NO) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) production was examined both in vitro and in vivo. In vitro study revealed that NLE treatment ($100{\mu}g/ml$) inhibits LPS (100 ng/ml)-induced NO production by 96% and TNF-${\alpha}$ production by 32%. The reduction in NO production is probably conferred by the complete suppression of inducible nitric oxide synthase (iNOS) expression. Interestingly, in vivo NLE significantly improved the survival rate of mice in an experimental sepsis model. Administration of NLE (100 mg/kg) 24 h before LPS treatment (20 mg/kg) improved the survival rate of mice by 60%. The inhibition of plasma NO and TNF-${\alpha}$ production by NLE is likely to account for the improved survival of mice. Our results suggest that NLE may present a promising avenue in the development of therapeutic agents for the treatment of inflammatory diseases.

Linarin is a main compound from Chrysanthemum zawadskii var, latilobum. However, the biological mechanisms of these activities are unclear. Because of this wide diversity of effects, it is believed that they may be exerted through pluripotent effectors of linarin. In our previous screening study, the effects of linarin on the mouse macrophages cell line, RAW 264.7 cells, were investigated. It was found that linarin could stimulate macrophages activation by the production of tumor necrosis factor (TNF). The linarin (6.25∼12.5 $\mu\textrm{g}$/mι) inhibited the production of NO in LPS-activated RAW 264.7 cells and linarin became an useful candidates for the development of new drug to treat endotoxemia and inflammation accompanied by the overproduction of NO. However, linarin-treated total lymphocyte showed cytotoxicity in a dose dependent manner between 20 $\mu\textrm{g}$/mι and 40 $\mu\textrm{g}$/mι. In this study, linarin derivative (acetylated linarin) was synthesized in order to obtain less-cytotoxicity of linarin and evaluated for their in vitro cytotoxic activity aganist mouse total lymphocyte. There was no cytotoxic activity in a dose dependent manner (20∼40 $\mu\textrm{g}$/mι) of acetylated linarin whereas linarin showed. The production of NO, however, was not the case by this modified linarin. The cell morphological change was not significantly changed in response to acetylated linarin alone and these effects were potentiated by the addition of LPS. These results suggest that acetylated linarin may be developed to be a promising new drug candidate without cytotoxicity on the basis of its activity of macrophage activation.

The purpose of this research was to investigate the anti-inflammatory effects of Yongdamsagantanghaphwangryunhaedogkagam(YSHHK) which has been medicated the patient such as breast cellulitis. YSHHK did not show any cytotoxic effect on mouse lung fibroblast cells at any of the concentrations evaluated(200, 100, 50, 10, 1 ${\mu}g/m{\ell}$). YSHHK in RAW264.7 cell inhibited $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, COX-2 and NOS-II mRNA genes expression in a concentration-dependent manner. YSHHK inhibited NO production significantly at the concentration of 100, 50 ${\mu}g/m{\ell}$ and ROS production in a concentration-dependent manner. YSHHK inhibited $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production significantly in serum of mice with LPS-induced acute inflammation. YSHHK increased survival rate of mice with LPS-induced lethal endotoxemia, compared to the control group, from the 3rd day onward. These results suggest that Yongdamsagantanghaphwangryunhaedogkagam(YSHHK) can be useful in treating mammary diseases caused by inflammation such as breast cellulitis.

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.
