Purpose: We developed a method to load lycopene into maltodextrin and cyclodextrin in an attempt to overcome the poor bioavailability and improve the anti-inflammatory effect of this polyphenol. Methods: Nanosized lycopenes were encapsulated into biodegradable amphiphillic cyclodextrin and maltodextrin molecules prepared using a high pressure homogenizer at 15,000~25,000 psi. Cell damage was induced by lipopolysaccharides (LPS) in a mouse macrophage cell line, RAW 264.7. The cells were subjected to various doses of free lycopene (FL) and nanoencapsulated lycopene (NEL). RT-PCR was used to quantify the tumor necrosis factor (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$), IL-6, inducible nitric oxide synthase (iNOS), and cyclooxigenase-2 (COX-2) mRNA levels, while ELISA was used to determine the protein levels of TNF-${\alpha}$, IL-$1{\beta}$, and IL-6. Results: NEL significantly reduced the mRNA expression of IL-6 and IL-$1{\beta}$ at the highest dose, while not in cells treated with FL. In addition, NEL treatment caused a significant reduction in IL-6 and TNF-${\alpha}$ protein levels, compared to cells treated with a similar dose of FL. In addition, mRNA expression of iNOS and COX-2 enzyme in the activated macrophages was more efficiently suppressed by NEL than by FL. Conclusion: Overall, our results suggest that lycopene is a potential inflammation reducing agent and nanoencapsulation of lycopene can further improve its anti-inflammatory effect during tissue-damaging inflammatory conditions.

In the present study, the possibility of whether the pharmacological effects of Scutellariae Radix Aqueous Extracts(SR) were favorably changed by report that lipopolysaccharide(LPS)-induced rat acute lung injury was treated with Red-Koji(Monascus purpureus 12002) fermentation. Three different dosages of Red-Koji fermented SR extract(fSR), 125, 250 and 500 mg/kg were orally administered once a day for 28 days before LPS(Escherichia coli 0111:B4) treatments, and then 5 hours after LPS treatment(500 ${\mu}g$/head, intra trachea instillation), all rats were sacrificed. Changes in the body weights, lung weights, pulmonary transcapillary albumin transit, arterial gas parameters(pH, $PaO_2$ and $PaCO_2$) bronchoalveolar lavage fluid(BALF) protein, lactate dehydrogenase(LDH) and proinflammatory cytokine tumor necrosis factor-${\alpha}$(TNF-${\alpha}$), interleukin-$1{\beta}$(IL-$1{\beta}$) contents, total cell numbers, neutrophil and alveolar macrophage ratios, lung malondialdehyde(MDA), myeloperoxidase(MPO), proinflammatory cytokine TNF-${\alpha}$ and IL-$1{\beta}$ contents were observed with histopathology of the lung, changes on luminal surface of alveolus(LSA), thickness of alveolar septum, number of polymorphonuclear neutrophils(PMNs). As results of LPS-injection, dramatical increases in lung weights, pulmonary transcapillary albumin transit increases in $PaCO_2$, decreases in pH of arterial blood and $PaO_2$, increases of BALF protein, LDH, TNF-${\alpha}$ and IL-$1{\beta}$ contents, total cells, neutrophil and alveolar macrophage ratios, lung MDA, MPO, TNF-${\alpha}$ and IL-$1{\beta}$ contents increases were detected with decreases in LSA and increases of alveolar septum and PMNs numbers, respectively as compared with intact control. Especially fSR 125 mg/kg showed quite similar favorable effects on the LPS-induced acute lung injuries as compared with 60 mg/kg of ${\alpha}$-lipoic acid and 250 mg/kg of SR. The results suggest that over 125 mg/kg of fSR extracts showed favorable effects on the LPS-induced acute lung injury mediated by their antioxidant and anti-inflammatory effects. Moreover, increases of the pharmacological effects of SR on LPS-induced acute lung injury were observed by Red-Koji fermentation in this study, at least 2-fold higher.

Bone resorption surrounding tooth root causes tooth loss in periodontitis patients. Osteoclast has bone resorption activity. Effects of Artemisia asiatica on bone resorption induced by periodontopathogens, Porphyromonas gingivalis and Treponema denticola, were examined using co-culture systems of mouse osteoblasts and bone marrow cells. Addition of A. asiatica ethanol extract to bacterial sonicate abolished bacteria-induced osteoclastogenesis. To determine inhibitory mechanism of A. asiatica against osteoclastogenesis, effects of A. asiatica on expressions of osteoclastogenesis-inducing factors such as receptor activator of NF-${\kappa}B$ ligand (RANKL), prostaglandin $E_2\;(PGE_2)$, interleukin (IL)-1, and tumor necrosis factor (TNF)-${\alpha}$, in osteoblasts were examined. A. asiatica suppressed expressions of RANKL, $PGE_2$, IL-$1{\beta}$, and TNF-${\alpha}$ increased by each bacterial sonicate. These results suggest inhibitory action of A. asiatica against osteoclastogenesis is associated with down-regulations of RANKL, $PGE_2$ IL-$1{\beta}$, and TNF-${\alpha}$ expressions.

Sparassis crispa is an edible mushroom with medicinal properties that contains more than 40% ${\beta}$-glucan. The role of S. crispa in regulating the functional activation of macrophages has yet to be fully elucidated. The objective of this study was to investigate the molecular mechanism underlying the immune-stimulatory function of S. crispa soluble ${\beta}$-glucan and extracts on macrophages. In this study, we showed that S. crispa soluble ${\beta}$-glucan was able to stimulate TNF-${\alpha}$ and IL-$1{\beta}$ production through NF-${\kappa}B$ activation in Raw 264.7 cells. We also showed that S. crispa extracts could not only enhance TNF-${\alpha}$ production in Raw 264.7 cells, but also suppress tumor growth in vivo. All of our results suggest that S. crispa could be developed as a promising immunostimulatory principle, applicable to cancer patients.

The essential oil fraction was obtained from the underground parts o of Ligusticum chuanxiong (Umbelliferae) by steam distillation, and its main components, Z-ligustilide and butylidene phthalide, were isolated by column chromatography. Its essential oil fraction and the isolated main components were examined for effects on their anti-inflammatory properties in RAW 264.7 macrophage cells to develop a new natural anti-inflammatory drug. The results showed that the L. chuanxiong essential oil fraction and its main components, Z-ligustilide and butylidene phthalide, inhibited the production of nitric oxide significantly in lipopolysaccharide (LPS)-treated RAW 264.7 cells. LPS-induced interleukin-$1{\beta}$ (IL-$1{\beta}$), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-$\alpha$) production was also decreased in a dose-dependent manner. In addition, western blot analysis revealed that the L. chuanxiong essential oil fraction and also its main components, Z-ligustilide, and butylidene phthalide reduced the expression levels of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS).

The purpose of this study was to observe the effects of Far-infrared on mice rheumatoid arthritis induced by type II collagen. The author peformed several experimental tests which were the hematoxylin-eosin tissue stain, the hind paw thickness, and ELSIA of cytokines(TNF-$\alpha$, IL-1$\beta$). On day 14 and 21, FIR-Tx. group decreased in synovial membrane thickness more than control II group FIR-Tx group decreased in hind paw thickness more than control II group. In the ELISA test of TNF-$\alpha$ concentration, control II group significantly increased in the concentration more than normal and FIR-Tx. group on day 7, 14, and 21. In the ELISA test of IL-$\beta$ concentration, FIR-Tx. group decreased in the concentration more than control II group on day 14 and 21. With J's Linear Function Data Process Program, researchers can get the estimated the concentration or the hind paw thickness from this experiment. The estimated results would be a good guide to therapists and researchers, planning Far-infrared application on the rheumatoid arthritis. These results indicated that far-infrared irradiating appeared to reduce the concentration of TNF-$\alpha$ and IL-1$\beta$ at mouse model of autoimmune arthritis. It would be considered that Far-infrared has an effect on relieving rheumatoid arthritis.

Ginger(Zingiber officinale Roscoe) has long been used as a food source in Korea, and it is widely used as a dietary condiment throughout the world. The present study focused on the immunomodulative effects of ginger extracts via in vitro experiments. To identify the immune-activation fractions of the plant, we performed the systematic fractionation of ginger with methanol, hexane, chloroform, butanol and water for separation and refining. The results showed that the chloroform fraction had the highest immune cell activation properties. In conclusion, this study suggests that ginger extracts may enhance immune function by regulating the splenocyte proliferation as well as the cytokine production capacity of activated macrophages.
