Objectives: This study was designed to examine the effect of Hominis Placenta Pharmacopuncture on the change in behavior, sleep-related hormones, inflammatory cytokines, anti-oxidants, weight, blood, and serum on rats given chronic physical stress. Methods: Wistar rats older than age 10 weeks were used in this experiment. They were divided into six groups. The normal group was not given stress. The control group was given only chronic physical stress and no treatment. The positive control group was given chronic physical stress and treated with zolpidem. Three Hominis Placenta Pharmacopuncture (HPP) groups were given chronic physical stress, then treated with different concentrations of HPP; HPP-0.5× (0.5 times diluted), HPP-1× (undiluted) and HPP-2× (2 times condensed). The changes of values of Nestlet Shredding results, weight, Melatonin, Gamma-aminobutylic Acid (GABA), Tumor Necrosis Factor Alpha (TNF-α), Interleukin-6 (IL-6), Superoxide dismutase (SOD), glutathione peroxidase (GPx), AST, ALT, BUN, Creatinine, and leukocytes were observed during the experiment. Results: The changes in chronic physical stress of the rat model were as follow. The Nestlet Shredding result increased in the control group compared to the normal group (p<0.05), and decreased in the HPP-1× and HPP-2× compared to the control group (p<0.05). The amount of weight gain showed increasing tendency in the HPP-2× compared to the control group since the second week. The GABA increased (p<0.05) and Melatonin also showed certain increasing tendency in the HPP-1× and HPP-2× compared to the control group. The TNF-α and IL-6 increased in the control group compared to the normal group (p<0.01), and decreased in all the HPPs compared to the control group (p<0.05). The SOD level decreased in the control group compared to the normal group (p<0.01), and increased in all the HPPs compared to the control group (p<0.05). GPx, AST, ALT, Bun, Creatinine and leukocytes showed no noticeable difference among all groups. Conclusions: Hominis Placenta Pharmacopuncture was effective in increasing weight, GABA, Melatonin, SOD, and decreasing Nestlet Shredding and inflammatory cytokines, suggesting that it consequently facilitates in relieving physical stress.

White adipose tissue is now recognized as an important endocrine organ which secretes various signal factors and proteins termed 'adipokine'. Haptoglobin (Hp), which has been known as an acute phase protein, belongs to the adipokine. However, the function of Hp in adipose tissue remains unclear. To verify the role of Hp in preadipocytes, in this study, 3T3-L1 preadipocyte cells were stably transfected with human Hp gene and Hp-overexpressing cells were made. The Hp had no effect on cell growth of preadipocytes. By RT-PCR and Western blot analysis, the Hp inhibited gene expression of IL-6 and COX-2 and enhanced HO-1 synthesis in preadipocytes. Moreover, invasion assay showed the Hp suppressed migration of monocytes to preadipocytes. These findings suggest that the Hp may inhibit an inflammatory reaction in adipose tissue by regulating the expressions of pro-inflammatory and anti-inflammatory mediators, and by repressing monocytes/macrophages infiltration.

This study demonstrated the immunological effects of methanol extracts from Doenjang added with wild plants (Pteridium aquilinum and Aster scaber) on bone-marrow derived macrophages and mouse splenocytes. Doenjang (DJ) and wild plant added Doenjang (WPDJ) extracts were treated to bone-marrow derived macrophages (BMDM) and splenocytes, and cell proliferation and cytokine production were measured. Cell proliferation of BMDM and splenocytes was more highly elevated in the WPDJ-treated group compared to the DJ-treated group. Cytokine [tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6, IL-$1{\beta}$, IL-10, and IL-12] production in BMDM also significantly increased in the WPDJ-treated group. Similarly, in the case of cytokine production in splenocytes, WPDJ treatment highly increased production of Th 1 type cytokines [interferon (IFN)-${\gamma}$ and IL-2] but did not affect production of Th 2 type cytokines (IL-4). These results suggest that wild plants could improve the immunomodulatory activity of Doenjang and may be effective for the development Doenjang.

Schisandra chinensis (SC) and Lycium chinense (LC) were widely distributed in Asia and the fruit has been used traditionally for medicinal herbs. The processing method was solid-state fermentation using Aspergillus oryzae for 48 h after stir-frying treatment at $220^{\circ}C$ for 12 min. In this study, in vitro the anti-inflammatory effect and in vivo hangover reduction were compared to unprocessed SC and LC water extract. Anti-inflammatory effects have been evaluated in pro-inflammatory mediators which were secreted by lipopolysaccharide (LPS)-induced RAW 264.7 macrophages. Nitric oxide (NO) was determined using Griess reaction. Proinflammatory cytokines such as tumor necrosis factor $(TNF)-{\alpha}$ and interleukin $(IL)-1{\beta}$ were measured by enzyme-linked immunosorbent assays (ELISA). Alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) activities were compared to processed SC or LC and mixtures thereof (1:1). In vivo study was compared to hangover relief in alcohol-fed mice. After administering a mixture of SC and LC (300 mg/kg) water extract (1:1), mice were fed 3 g/kg of ethanol. Serum was collected at 1, 3, and 5 h intervals to analyze ethanol and acetaldehyde levels using a colorimetric assay kit. The processed SC and LC water extracts compared to raw materials significantly inhibited LPS-induced NO and inflammatory cytokine production in RAW 264.7 cells. The results of the hangover mouse model are also consistent with anti-inflammatory effects. These results suggest that processed SC and LC extracts may be functional materials for the treatment of inflammation and hangover.

Unripe astringent persimmon (Diospyros kaki Thunb. cv. Cheongdo-Bansi) is a by-product produced when thinning out the superfluous fruit of persimmon. We investigated whether unripe astringent persimmon has antioxidative and anti-inflammatory effects. Unripe astringent persimmon extract was fractionated sequentially in n-hexane, chloroform, ethyl acetate, n-butanol, and water. The ethyl acetate fraction had the highest total phenolic content, total flavonoid content, and antioxidant capacity compared to those of the other fractions. Pretreatment of lipopolysaccharide-stimulated RAW 264.7 macrophages with the ethyl acetate fraction reduced nitric oxide, interleukin-6, and intracellular oxidative stress in a dose-dependent manner. Ultra-high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry analysis revealed gallic acid, protocatechuic acid, 4-hydroxybenzoic acid, quercetin-3-O-glucoside, quercetin, and p-coumaric acid as the phenolic compounds of the ethyl acetate fraction. Collectively, these findings suggest that unripe astringent persimmon is a source of functional materials that can promote antioxidative and anti-inflammatory effects.

Aster yomena (Kitam.) Honda is an edible vegetable and perennial herb belonging to the Asteraceae family, and has been used for a long time for the prevention and treatment of various diseases. Although leaf extracts of A. yomena are known to have antioxidant and anti-inflammatory effects, accurate efficacy assessments are still inadequate. In this study, we investigated whether the antioxidant efficacy of ethanol extract of A. yomena leaf (EEAY) is correlated with the anti-inflammatory effect in RAW 264.7 macrophages. The results showed that EEAY significantly inhibited the hydrogen peroxide ($H_2O_2$)-induced growth inhibition in RAW 264.7 cells, which was associated with increased expression of nuclear factor erythroid 2-related factor-2 (Nrf2) and heme oxygenase-1 (HO-1). EEAY pretreatment also effectively prevented $H_2O_2$-induced reactive oxygen species generation and apoptosis through inhibition of caspase-3 activation and poly (ADP-ribose) polymerase degradation. Additionally, EEAY significantly increased the expression and production of interleukin-10, a representative anti-inflammatory cytokine, which was associated with increased expression of toll-like receptor 4 and myeloid differentiation factor 88 at transcriptional and translational levels. Furthermore, the increased production of nitric oxide (NO) by lipopolysaccharide was markedly abolished under the condition of EEAY pretreatment, and the inhibitory effect of NO production by EEAY was further increased by hemin, an HO-1 inducer. Overall, our results suggest that EEAY is able to activate the Nrf2/HO-1 signaling pathway to protect RAW 264.7 macrophages from oxidative and inflammatory stress.

BACKGOURND/OBJECTIVES: Vascular inflammation is an important feature in the atherosclerotic process. Recent studies report that leaves and branches of Carpinus turczaninowii (C. turczaninowii) have antioxidant capacity and exert anti-inflammatory effects. However, no study has reported the regulatory effect of C. turczaninowii extract on the arterial inflammatory response. This study therefore investigated modulation of the arterial inflammatory response after exposure to C. turczaninowii extract, using human aortic vascular smooth muscle cells (HAoSMCs). MATERIALS/METHODS: Scavenging activity of free radicals, total phenolic content (TPC), cell viability, mRNA expressions, and secreted levels of cytokines were measured in LPS-stimulated (10 ng/mL) HAoSMCs treated with the C. turczaninowii extract. RESULTS: C. turczaninowii extract contains high amounts of TPC ($225.6{\pm}21.0mg$ of gallic acid equivalents/g of the extract), as well as exerts time-and dose-dependent increases in strongly scavenged free radicals (average $14.8{\pm}1.97{\mu}g/mL$ $IC_{50}$ at 40 min). Cell viabilities after exposure to the extracts (1 and $10{\mu}g/mL$) were similar to the viability of non-treated cells. Cytokine mRNA expressions were significantly suppressed by the extracts (1 and $10{\mu}g/mL$) at 6 hours (h) after exposure. Interleukin-6 secretion was dose-dependently suppressed 2 h after incubation with the extract, at $1-10{\mu}g/mL$ in non-stimulated cells, and at 5 and $10{\mu}g/mL$ in LPS-stimulated cells. Similar patterns were also observed at 24 h after incubation with the extract (at $1-10{\mu}g/mL$ in non-stimulated cells, and at $10{\mu}g/mL$ in the LPS-stimulated cells). Soluble intracellular vascular adhesion molecules (sICAM-1) secreted from non-stimulated cells and LPS-stimulated cells were similarly suppressed in a dose-dependent manner after 24 h exposure to the extracts, but not after 2 h. In addition, sICAM-1 concentration after 24 h treatment was positively related to IL-6 levels after 2 h and 24 h exposure (r = 0.418, P = 0.003, and r = 0.524, P < 0.001, respectively). CONCLUSIONS: This study demonstrates that C. turczaninowii modulates the arterial inflammatory response, and indicates the potential to be applied as a therapeutic use for atherosclerosis.

Objectives. Regenerative treatment using stem cells may serve as treatment option for empty nose syndrome (ENS), which is caused by the lack of turbinate tissue and deranged nervous system in the nasal cavity. We aimed to assess the efficacy and safety of the autologous stromal vascular fraction (SVF) in the treatment of ENS. Methods. In this prospective observational clinical study, we enrolled 10 ENS patients who volunteered to undergo treatment of ENS through the injection of autologous SVF. Data, including demographic data, pre- and postoperative Sino-Nasal Outcome Test-25 (SNOT-25) scores, overall patient satisfaction, and postoperative complications, were prospectively collected. Nasal secretion was assessed using the polyurethane foam absorption method, and the levels of biological markers were analyzed in both ENS group and control group using enzyme-linked immunosorbent assay. The SVF extracted from abdominal fat was diluted and injected into both inferior turbinates. Results. Among the 10 initial patients, one was excluded from the study. Subjective satisfaction was rated as "much improved" in two and "no change" in seven. Among the improved patients, the mean preinjection SNOT-25 score was 55.0 and the score at 6 months after injection was 19.5. However, the average SNOT-25 score of nine participants at 6 months after injection (mean${\pm}$standard deviation, $62.4{\pm}35.8$) did not differ significantly from the baseline SNOT-25 score ($70.1{\pm}24.7$, P>0.05, respectively). Among the various inflammatory markers assessed, the levels of interleukin $(IL)-1{\beta}$, IL-8, and calcitonin gene-related peptide were significantly higher in ENS patients. Compared with preinjection secretion level, the nasal secretions from SVF-treated patients showed decreased expressions of $IL-1{\beta}$ and IL-8 after injection. Conclusion. Although SVF treatment appears to decrease the inflammatory cytokine levels in the nasal mucosa, a single SVF injection was not effective in terms of symptom improvement and patient satisfaction. Further trials are needed to identify a more practical and useful regenerative treatment modality for patients with ENS.

Background: The purpose of this study was to investigate the anti-oral microbial activity and anti-inflammatory effects of rosmarinic acid (RA) in lipopolysaccharide (LPS)-stimulated MC3T3-E1 osteoblastic cells on a titanium (Ti) surface during osseointegration, and to confirm the possibility of using RA as a safe natural substance for the control of peri-implantitis (PI) in Ti-based dental implants. Methods: A disk diffusion test was conducted to confirm the antimicrobial activity of RA against oral microorganisms. In order to confirm the anti-inflammatory effects of RA, inflammatory conditions were induced with 100 ng/ml of LPS in MC3T3-E1 osteoblastic cells on the Ti surface treated with or without 14 ㎍/ml of RA. The production of nitric oxide (NO) and prostaglandin E2 (PGE2) in LPS-stimulated MC3T3-E1 osteoblastic cells on the Ti surface was confirmed using an NO assay kit and PGE2 enzyme-linked immunosorbent assay kit. Reverse transcription polymerase chain reaction and western blot analysis were performed to confirm the expression of interleukin (IL)-1β and tumor necrosis factor (TNF)-α in total RNA and protein. Results: RA showed weak antimicrobial effects against Streptococcus mutans and Escherichia coli, but no antimicrobial activity against the bacteria Aggregatibacter actinomycetemcomitans and the fungus Candida albicans. RA reduced the production of pro-inflammatory mediators, NO and PGE2, and proinflammatory cytokines, TNF-α and IL-1β, in LPS-stimulated MC3T3-E1 osteoblastic cells on the Ti surface at the protein and mRNA levels. Conclusion: RA not only has anti-oral microbial activity, but also anti-inflammatory effects in LPS-stimulated MC3T3-E1 osteoblasts on the Ti surface, therefore, it can be used as a safe functional substance derived from plants for the prevention and control of PI for successful Ti-based implants.

Objective: This research aimed to study the effects of Artemisia argyi flavonoids (AAF) supplemented in diets on the growth performance and immune function of broiler chickens challenged with lipopolysaccharide (LPS). Methods: A total of one hundred and ninety-two 1-d-old broiler chicks were assigned into 4 treatment groups, which were, respectively, fed a basal diet (control), fed a diet with 750 mg/kg AAF, fed a basal diet, and challenged with LPS, fed a diet with 750 mg/kg AAF, and challenged with LPS. Each treatment had six pens with 8 chicks per pen. On days 14, 16, 18, 20 (stress phase I) and 28, 30, 32, 34 (stress phase II), broilers were injected with LPS (500 ㎍/kg body weight) or an equivalent amount of saline. Results: The results demonstrated that dietary AAF significantly improved the body weight (d 21) and alleviated the decrease of average daily gain in broilers challenged with LPS on d 21 and d 35 (p<0.05). Dietary AAF increased bursa fabricius index, and dramatically attenuated the elevation of spleen index caused by LPS on d 35 (p<0.05). Furthermore, serum interleukin-6 (IL-6) concentration decreased with AAF supplementation on d 21 (p<0.05). Diet treatment and LPS challenge exhibited a significant interaction for the concentration of IL-1β (d 21) and IL-6 (d 35) in serum (p<0.05). Additionally, AAF supplementation mitigated the increase of IL-1β, IL-6 in liver and spleen induced by LPS on d 21 and 35 (p<0.05). This study also showed that AAF supplementation significantly reduced the expression of IL-1β (d 21) and nuclear transcription factor kappa-B p65 (d 21 and 35) in liver (p<0.05), and dietary AAF and LPS treatment exhibited significant interaction for the gene expression of IL-6 (d 21), toll like receptor 4 (d 35) and myeloid differentiation factor 88 (d 35) in spleen (p<0.05). Conclusion: In conclusion, AAF could be used as a potential natural immunomodulator to improve growth performance and alleviate immune stress in broilers challenged with LPS.
