Surface modified poly ${\text\tiny{L}}$-lactic acid (PLLA) samples with hydroxyapatite (HA), heparin and bone morphogenetic protein-2 (BMP-2) mediated by polydopamine (pDA) coating (PLLA/pDA/HA/Hep/BMP-2) were prepared, and their effects on the enhancements of bone formation and osseointegration were evaluated in vitro and in vivo as compared to PLLA, PLLA/pDA/HA, and PLLA/pDA/Hep/BMP-2. The changes in surface chemical compositions, morphologies and wettabilities were observed by X-ray photoelectron spectroscopy (XPS), field-emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM) and water contact angle measurements. Pre-coating of HA particles with pDA provided uniform and homogeneous anchoring of particles to PLLA surface. In addition, the strong ionic interaction between heparin and pDA led PLLA surface readily heparinized for loading of BMP-2. In vitro experiments revealed that the levels of alkaline phosphatase (ALP) activity, calcium deposition, and osteocalcin (OCN) gene expression were higher in MG-63 human osteosarcoma cell lines grown on PLLA/pDA/HA/Hep/BMP-2 than on control PLLA, PLLA/pDA/HA, and PLLA/pDA/Hep/BMP-2. In vivo studies using micro-computed tomography (micro-CT) also showed that PLLA/pDA/HA/Hep/BMP-2 screw exhibited greatest value of bone volume (BV) and bone volume/tissue volume (BV/TV) among samples. Histological evaluations with H&E and Von Kossa staining demonstrated that a combination of HA and BMP-2 contributed to the strong osseointegration.

Chan-Su (Venenum bufonis) has long been for a variety of other purposes including treatment of inflammation in the folk medicine recipe. Since nitric oxide (NO) is one of the major inflammatory parameters, we first studied the effects of Chan-Su on NO production in lipopolysaccharide (LPS)-stimulated BV2 microglial cells, Chan-Su inhibited the secretion of NO in BV2 microglial cells, without affecting cell viability, The protein level of inducible nitric oxide synthase (iNOS) was decreased by Chan-Su, And Chan-Su also inhibited production of prostaglandin E2 (PGE2) and expression of cyclooxygenase (COX)-2. Proinflammatory cytokines, such as tumor necrosis factor $(TNF)-{\alpha}$, interleukin $(IL)-1{\beta}$ and IL-12, were inhibited by Chan-Su in a dose-dependent manner. And Chan-Su inhibited the degradation of ${IkB-\alpha}$, which was considered to be inhibitor of nuclear factor $(NF)-{\kappa}B$, one of a potential transcription factor for the expression of iNOS, COX-2 and proinflammatory cytokines. These results suggest that Chan-Su could exert its anti-inflammatory actions by suppressing the synthesis of NO through inhibition of $I{\kappa}B-{\alpha}$ degradation.

Objectives: This study was performed to analyse four week repeated dose toxicity of Sweet Bee Venom(Sweet BV) extracted from the bee venom in Beagle dogs. Methods: All experiments were conducted under the regulations of Good Laboratory Practice (GLP) at Biotoxtech Company, a non-clinical study authorized institution. Male and female Beagle dogs of 5-6 months old were chosen for the pilot study of four week repeated dose toxicity of Sweet BV which was administered at the level of 0.56mg/kg body weight which is eighty times higher than the clinical application dosage as the high dosage, followed by 0.28 and 0.14mg/kg as midium and low dosage, respectively. Equal amount of excipient(normal saline) to the Sweet BV experiment groups was administered as the control group every day for four weeks. Results: 1. No mortality was witnessed in all of the experiment groups. 2. All experiment groups were appealed pain sense in the treating time compared to the control group, and hyperemia and movement disorder were observed around the area of administration in all experiment groups, and higher occurrence in the higher dosage treatment. 3. For weight measurement, Neither male nor female groups showed significant changes. 4. In the urine analysis, CBC and biochemistry didn't show any significant changes in the experiment groups compared with control group. 5. For weight measurement of organs, experiment groups didn't show any significant changes compared with control group. 6. To verify abnormalities of organs and tissues, thigh muscle which treated with Sweet BV, cerebrum, liver, lung, kidney, and spinal cords were removed and conducted histologocal observation with H-E staining. In the histologocal observation of thigh muscle, cell infiltration, inflammatory, degeneration, necrosis of muscle fiber, and fibrosis were found in both thigh tissue. And the changes were depend on the dose of Sweet BV. But another organs were not detected in any abnormalities. 7. The proper high dosage of Sweet BV for the thirteen week repeated test in Beagle dogs may be 0.28mg/kg in one time. Conclusion: Above findings suggest that Sweet BV is relatively safe treatment medium. Further studies on the subject should be conducted to yield more concrete evidences.

Objectives : In this study, we compared the anti-oxidant and anti-inflammatory activities of Curcumae longae Radix (CLRa) and Curcumae longae Rhizoma (CLRh). Methods : We performed 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and 2,2-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) cation scavenging assays, and determined total polyphenolic content to examine the anti-oxidant effects of CLRa and CLRh. We also evaluated the anti-oxidant effects of CLRa and CLRh against hydrogen peroxide ($H_2O_2$)-induced toxicity in PC12 cells using thiazolyl blue tetrazolium bromide (MTT) and reactive oxygen species (ROS) assays. Next, to compare the anti-inflammatory effects of CLRa and CLRh against lipopolysaccharide (LPS)-induced inflammation in microglia BV2 cells, we measured nitric oxide (NO) assay and inducible nitrite synthase (iNOS) using Western blotting analysis. Results : CLRa showed higher activity in DPPH and ABTS assays and lower total polyphenolic contents compared with CLRh. In PC12 cells, CLRa and CLRh showed no difference in H2O2-induced cell toxicity and ROS overproduction. In BV2 cells, CLRa showed higher effect than CLRh in NO and iNOS production induced by LPS. Conclusions : These results demonstrate that CLRa has higher radical scavenging activities and anti-inflammatory effect in BV2 cells comparing CLRh. However, CLRa and CLRh have no effect and no difference in $H_2O_2$-induced toxicity.
Objectives : The root of Zingiber officinale ROSC. (Zingiberis Rhizoma Recens; Ginger) has been widely used as one of folk remedies and food materials in many traditional preparations. Ginger is known as an effective appetite enhancer and anti-inflammatory agent. This study was performed to investigate the effect of ginger chloroform fraction (GCF) in microglia which play a central role on brain inflammation in neurodegenerative diseases. Methods : Dried ginger was extracted with 80% methanol, and then fractionated with chloroform. BV2 mouse microglial cells were cultured with different concentrations of GCF and then stimulated with LPS (1 ${\mu}g/m{\ell}$) at indicated times. The cell toxicity of GCF was determined by MTT assay. The concentrations of NO, PGE2 and cytokines were measured by Griess assay and enzyme-linked immunosorbant assay. The mRNA and protein expressions of iNOS, COX-2 and cytokines were determined by RT-PCR and Western blotting. The phosphorylation of three MAPKs (p38 MAPK, ERK1/2 and JNK) and $NF-{\kappa}B$ activation were determined by Western blotting. Results : GCF significantly inhibited LPS-induced production of inflammatory mediators, NO, $PGE_2$ and proinflammatory cytokines ($TNF-{\alpha}$ and $IL-1{\beta}$) in a dose-dependent manner. GCF attenuated LPS-induced expression of mRNA and protein of inflammatory enzymes, iNOS, COX-2 and proinflammatory cytokines through suppressing the phosphorylation of ERK1/2 and p38 MAPK and the activation of p65 $NF-{\kappa}B$ in BV2 cells. Conclusions : This study suggests that GCF may have an anti-inflammatory property through suppressing the inflammatory mediator production released by activated microglia after the brain injury.
Background: The purpose of this study was to prospectively evaluate the predictive value of perfusion computed tomography (CT) for response of local advanced esophageal carcinoma to radiotherapy and chemotherapy. Materials and Methods: Before any treatment, forty-three local advanced esophageal squamous cell carcinomas were prospectively evaluated by perfusion scan with 16-row CT from June 2009 to January 2012. Perfusion parameters, including perfusion (BF), peak enhanced density (PED), blood volume (BV), and time to peak (TTP) were measured using Philips perfusion software. Seventeen cases received definitive radiotherapy and 26 received concurrent chemo-radiotherapy. The response was evaluated by CT scan and esophagography. Differences in perfusion parameters between responders and non-responders were analyzed, and ROCs were used to assess predictive value of the baseline parameters for treatment response. Results: There were 25 responders (R) and 18 non-responders (NR). Responders showed significantly higher BF (R:34.1 ml/100g/min vs NR: 25.0 ml/100g/min, p=0.001), BV (23.2 ml/100g vs 18.3 ml/100g, p=0.009) and PED (32.5 HU vs 28.32HU, P=0.003) than non-responders. But the baseline TTP (R: 38.2s vs NR: 44.10s, p=0.172) had no difference in the two groups. For baseline BF, a threshold of 36.1 ml/100g/min achieved a sensitivity of 56%, and a specificity of 94.4% for detection of clinical responders from non-responders. Conclusions: The results suggest that the perfusion CT can provide some helpful information for identifying tumors that may respond to radio-chemotherapy.
