Background: Beneficial effects of Korean Red Ginseng (KRG) on polycystic ovarian syndrome (PCOS) remains unclear. Methods: We examined whether pretreatment (daily from 2 hours before PCOS induction) with KRG extract in water (KRGE; 75 and 150 mg/kg/day, p.o.) could exert a favorable effect in a dehydroepian-drosterone (DHEA)-induced PCOS rat model. Results: Pretreatment with KRGE significantly inhibited the elevation of body and ovary weights, the increase in number and size of ovarian cysts, and the elevation of serum testosterone and estradiol levels induced by DHEA. Pretreatment with KRGE also inhibited macrophage infiltration and enhanced mRNA expression levels of chemokines [interleukin (IL)-8, monocyte chemoattractant protein-1), proinflammatory cytokines (IL-1β, IL-6), and inducible nitric oxide synthase in ovaries induced by DHEA. It also prevented the reduction in mRNA expression of growth factors (epidermal growth factor, transforming growth factor-beta (EGF, TGF-β)) related to inhibition of the nuclear factor kappa-light-chain-enhancer of activated B cell pathway and stimulation of the nuclear factor erythroid-derived 2-related factor 2 pathway. Interestingly, KRGE or representative ginsenosides (Rb1, Rg1, and Rg3(s)) inhibited the activity of inflammatory enzymes cyclooxygenase-2 and iNOS, cytosolic p-IκB, and nuclear p-nuclear factor kappa-light-chain-enhancer of activated B in lipopolysaccharide-induced RAW264.7 cells, whereas they increased nuclear factor erythroid-derived 2-related factor 2 nuclear translocation. Conclusion: These results provide that KRGE could prevent DHEA-induced PCOS via antiinflammatory and antioxidant activities. Thus, KRGE may be used in preventive and therapeutic strategies for PCOS-like symptoms.

Objectives : The present study was examined to evaluate the anti-inflammatory effects of the Humulus japonicus MeOH extracts (HJE) in vivo. Methods : The effects of HJE on anti-inflammation were measured by production of NO, iNOS (inducible Nitric Oxide Synthase), COX-2, I$\kappa$B$\alpha$ (Inhibitor kappa B alpha), NF$\kappa$B (Nuclear Factor kappa B), TNF-$\alpha$ (Tumor Necrosis Factor-alpha) and IL-1$\beta$ (Interleukin-1$\beta$), IL-6 in Raw 264.7 macrophage cells stimulated with LPS. Results : 1. All concentrations of HJE(0.03 and 0.10 mg/ml) had no significant cytotoxicity in Raw 264.7 cell during the entire experimental period. 2. The level of NO and iNOS in culture medium was dramatically increased by LPS application. However, these increases were dose-dependently(0.03 and 0.10 mg/ml) attenuated by treatment with HJE. 3. HJE extract reduced PGE2 levels in a dose-dependent manner as a consequence of inhibition of COX-2 protein expression in Raw 264.7 macrophage cells stimulated with LPS. 4. 0.10 mg/ml HJE significantly inhibited the phosphorylation of I$\kappa$B$\alpha$ indicating the suppression of NF-$\kappa$B pathway in Raw 264.7 macrophage cells stimulated with LPS. 5. 0.10 mg/ml HJE significantly inhibited the production of TNF-$\alpha$ in Raw 264.7 macrophage cells stimulated with LPS. 6. All concentrations of HJE significantly inhibited the production of IL-1$\beta$, IL-6 in Raw 264.7 macrophage cells stimulated with LPS. Conclusions : These results provide evidences that therapeutic effect of HJE on heat syndrome, especially due to the acute inflammation, are partly due to the reduction of some of inflammatory factors by inhibiting iNOS and COX-2 through the suppression of p-I$\kappa$B$\alpha$. Moreover, it suggests that the mechanism of action of HJE comes from the suppression of inflammatory mediators, such as NO, PGE$_2$ and pro-inflammatory cytokines.

Objectives : The present study was conducted to evaluate the anti-inflammatory effects of the Gamroeum water extracts (GRE) in vivo and in vitro. Methods : The effects of GRE on anti-inflammation were measured by production of NO, $PGE_2$ (Prostaglandin $E_2$), iNOS (inducible Nitric Oxide Synthase), COX-2, $NF{\kappa}B$ (Nuclear Factor kappa B), TNF-$\alpha$ (Tumor Necrosis Factor-alpha) and IL-$1{\beta}$ (Interleukin-$1{\beta}$), IL-6 in Raw 264.7 macrophage cells stimulated with LPS. Results : 1. In machrophage cells, LPS displayed significant stimulatory effects on the production of NO and $PGE_2$. However, GRE showed significant inhibitory effects on NO and $PGE_2$ release. The level of NO and $PGE_2$ was decreased by GRE in a concentration dependent manner as compared with LPS only group. 2. Immunoblot analysis verified that LPS stimulation significantly increased the iNOS and COX-2 protein level, but GRE suppressed the induction of iNOS and COX-2 protein at a concentration dependent manner. 3. GRE reduced the elevated production of TNF-$\alpha$, IL-$1{\beta}$ and IL-6 by LPS. Moreover, the inhibitory effects of GRE was occurred in a dose-dependent manner. 4. GRE significantly reduced the expression of NF-${\kappa}B$ protein in nuclear fraction. 5. GRE effectively inhibited the increases of hind paw skin thicknesses and inflammatory cell infiltrations induced by carrageenan treatment. It, therefore, considered that GRE will be favorably inhibited the acute edematous inflammations. Conclusions : These results indicated that GRE could have anti-inflammatory capacity by inhibiting the production of NO, $PGE_2$ and cytokines in vitro and by reducing the formation of carrageenan-induced paw edema in vivo. Moreover, inhibitory effects of GRE on the macrophage activation were attributable to the reduction of some of inflammatory factors by inhibiting iNOS and COX-2 through the suppression of NF-${\kappa}B$.

Background: The molecular mechanisms linking breast cancer progression and inflammation still remain obscure. The aim of the present study was to investigate the possible association of angiopoeitin like protein 4 (ANGPTL4) and its regulatory factor, hypoxia inducible factor-$1{\alpha}$ (HIF-$1{\alpha}$), with the inflammatory markers nuclear factor kappa B/p65 (NF-${\kappa}B$/P65) and interleukin-1 beta (IL-$1{\beta}$) in order to evaluate their role in inflammation associated breast cancer progression. Materials and Methods: Angiopoietin-like protein 4 (ANGPTL4) mRNA expressions were evaluated using quantitative real time PCR and its protein expression by immunohistochemistry. DNA binding activity of NF-${\kappa}B$/P65 was evaluated by transcription factor binding immunoassay. Serum levels of ANGPTL4, HIF-$1{\alpha}$ and IL-$1{\beta}$ were immunoassayed. Tumor clinico-pathological features were investigated. Results: ANGPTL4 mRNA expressions and serum levels were significantly higher in high grade breast carcinoma ($1.47{\pm}0.31$ and $184.98{\pm}18.18$, respectively) compared to low grade carcinoma ($1.21{\pm}0.32$ and $171.76{\pm}7.58$, respectively) and controls ($0.70{\pm}0.02$ and $65.34{\pm}6.41$, respectively), (p<0.05). Also, ANGPTL4 high/moderate protein expression was positively correlated with tumor clinico-pathological features. In addition, serum levels of HIF-$1{\alpha}$ and IL-$1{\beta}$ as well as NF-${\kappa}B$/P65 DNA binding activity were significantly higher in high grade breast carcinoma ($148.54{\pm}14.20$, $0.79{\pm}0.03$ and $247.13{\pm}44.35$ respectively) than their values in low grade carcinoma ( $139.14{\pm}5.83$, $0.34{\pm}0.02$ and $184.23{\pm}37.75$, respectively) and controls ($33.95{\pm}3.11$, $0.11{\pm}0.02$ and $7.83{\pm}0.92$, respectively), (p<0.001). Conclusion: ANGPTL4 high serum levels and tissue expressions in advanced grade breast cancer, in addition to its positive correlation with tumor clinico-pathological features and HIF-$1{\alpha}$ could highlight its role as one of the signaling factors involved in breast cancer progression. Moreover, novel correlations were found between ANGPTL4 and the inflammatory markers, IL-$1{\beta}$ and NF-${\kappa}B$/p65, in breast cancer, which may emphasize the utility of these markers as potential tools for understanding interactions for axes of carcinogenesis and inflammation contributed for cancer progression. It is thus hoped that the findings reported here would assist in the development of new breast cancer management strategies that would promote patients' quality of life and ultimately improve clinical outcomes. However, large-scale studies are needed to verify these results.

Cardiopulmonary bypass (CPB) for cardiac surgery triggers the production and release of numerous chemotactic substances and cytokines, ensuing systemic inflammatory response that leads to postoperative major organ dysfunction. Traditionally, corticosteroids (steroid) have been administered to patients undergoing cardiac surgery to ward off these detrimental physiologic alterations. However, the majority of the studies have been performed on adult patients with high-dose steroid. We carried out a randomized, prospective, double-blind study to compare the efficacy of low-dose steroid with that of high-dose steroid and to determine the adequate dose of pretreated-steroid for prophylactic effects in pediatric cardiac surgery. Thirty pediatric patients scheduled for elective cardiac surgery were randomly assigned to two groups; fifteen patients received low-dose methylprednisolone (10mg/kg intravenously, n=15, low-dose group) and the others received high-dose methylprednisolone (30mg/kg intravenously, n=15, high-dose group) 1 hour prior to CPB. Arterial blood samples were taken before CPB (Pre-CPB), 10 minutes after start of CPB (CPB-10), and immediately after CPB-end (CPB-OFF) for measuring total leukocyte counts (T-WBC) and diff-counts, platelet counts, interleukin-6 (IL-6), myeloperoxidase (MPO), total antioxidant (TAO), neuron-specific enolase (NSE), troponin I (TNI), aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine, and blood urea nitrogen (BUN) levels. Other parameters such as volumes of urine output, pulmonary index $(PI,\;PaO_2/FiO_2)$, mechanical ventilating period, intensive care unit (ICU)-staying period, postoperative complications (fever, wound problem), postoperative 24 hrs and total volumes in blood loss, and hospitalized days were also assessed. All parameters were compared between two groups. There were no significant differences in T-WBC counts, monocyte fraction, platelet counts, TA levels, NSE levels, creatinine levels, BUN levels, the volumes of total urine output, PI, the incidences of fever and wound problem, postoperative 24hrs- and total-blood loss volumes and ICU-staying period between two groups (P>0.05). At CPB-OFF, neutrophil fraction, MPO level, TNI level, and AST level were higher in the high-dose group than in the low-dose group (P<0.05). IL-6 level at CPB-10 was higher in the high dose-group than in the low-dose group (P<0.05). Furthermore, mechanical ventilating periods and hospitalized days of the high-dose group were significantly longer than those of low-dose group (P<0.05). The high-dose group had significantly low lymphocyte fi-action at CPB-OFF compared with the low-dose group (P<0.001). These findings suggest that pretreatment of high-dose steroid is not superior to that of low-dose steroid regrading its potential benefits in pediatric cardiac surgery. Therefore, the conventional strategy of steroid treatment, high-dose pretreatment, should be modified in the cardiac surgery with CPB. However, further studies must be performed on the larger number of patients in as much as small number of patients in this study.
