| 1 | Potential immunomodulation effect of the extract of Nigella sativa on ovalbumin sensitized guinea pigs显示文摘Several different pharmacological effects have been described for Nigella sativa(Siah-Daneh) ,including an anti-inflammatory effect.In the present study,the effect of the extract of N.sativa on lung pathology and blood interleukin-4(IL-4) and interferon-γ(IFN-γ) of sensitized guinea pigs was examined.Three groups(n=8 for each group) of guinea pigs sensitized to ovalbumin(OA) were given drinking water alone,and drinking water containing low and high concentrations of the plant extract,respectively.The animals of the control group(n=8) were treated with saline instead of OA and were given drinking water.The pathological changes of the lung,including infiltration of eosinophils and lymphocytes,local epithelial necrosis,the presence of oedema,thickening of the basement membrane,smooth muscle layer hypertrophy,mucosal secretion,and the presence of mucosal plug,and blood IL-4 and IFN-γof sensi-tized guinea pigs were evaluated.The lungs of the sensitized group showed significant pathological changes(P<0.001) .Blood IL-4 and IFN-γwere increased in sensitized animals compared to the controls(P<0.01 and P<0.001,respectively) .Treatment of sensitized animals with the extract led to a significant decrease in pathological changes of the lung(P<0.01 to P<0.001) ,except for the oedema in the sensitized group treated with low concentration of the extract,but an increased IFN-γ.These results confirm a preventive effect of N.sativa extract on lung inflammation of sensitized guinea pigs. | Mohammad-Hossein BOSKABADY Rana KEYHANMANESH Saeed KHAMENEH Yousef DOOSTDAR Mohammad-Reza KHAKZAD | 2011 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2011，12，3： | 2 |

| 18 | The Study of the Grit-blasting Parameters and Their Effects on the Adhesive Strength of the Plasma Sprayed Coatings显示文摘Surface Preparation is very important in adhesive b on ding of spray coatings to the surface of a work piece. The common practice is gr it-blasting of the surface before subjecting it to the spray coating process. In this study, grit-blasting of an AISI 4130 steel (of different heat treatmen ts) with Al 2O 3 particles was studied. Various grit-blasting parameters such as blasting particle size, the distance between blasting nozzle and the work pi ece (25, 30 and 40 cm.), blasting pressure (3,4,5,6 and 7 bars), blasting time ( 3, 6 and 10 seconds), and the blasting angle (45° and 90°) were examined in or der to find the optimum roughness. The mean roughness (Ra) of the grit-blasted surfaces were measured and the vari ations of the roughness with respect to the above mentioned variables were studi ed. The results show that by increasing blasting time, surface roughness increas es up to a maximum and then slightly decreases it with further duration of t he process. On the other hand a lengthy blasting causes some undesirable results such as an increase in residual particles between surface irregularities. There fore an optimum blasting time is of great importance. Increasing the blasting pr essure also provides a rougher surface, but in grit blasting of harder specimens the surface roughness decreases when the pressure reaches a certain limit. About the blasting angle, it was noticed that an angle of 45° results in less r esidual particles between the surface irregularities, in comparison to the angle of 90°. After grit-blasting, the specimens were plasma spray coated with 80% ZrO 2-20 % Y 2O 3 powder. The adhesive strength of the coating to the substrate was the n measured according to the DIN 50160 standard. The results show that for a certain base metal, the adhesive strength is directl y related to the surface roughness of the base material. Residual particles afte r grit-blasting the surface of the specimens can also have a strong deteriorati ng effect on adhesive strength. Finally, it was shown that the hardness of the b ase material had a direct effect on the adhesive strength of the sprayed coating s. | M Heydarzadeh Sohi M Frooghieh Sh Khameneh Asl | 2002 | 厦门大学学报(自然科学版)2002，41，S1： | 0 |
