目的以SHR和WKy大鼠为实验对象,通过测量相关指标,观察复方钩藤降压片对p2y6受体的表达及炎症水平的影响。方法60只SHR随机分为5组,即模型对照组、缬沙坦组、阻断剂组、钩藤组、中西药组,另12只WKy大鼠设置为空白对照组,按相应的处理方法连续干预8周后取材,测算HMI和LVMI、HE染色观察左室心肌形态、免疫组化法检测心脏IL-1β、IL-6和TNF-α的蛋白表达、RT-pCR法测定IL-6、TNF-α、IL-1β、p2y6 mRNA的表达、Western-Blotting法测定心肌IL-6、TNF-α、IL-1β、p2y6的蛋白表达。结果⑴自发性高血压大鼠心室重量及左室质量较正常大鼠明显增加,是良好的高血压LVH的研究模型;⑵自发性高血压大鼠炎症因子IL-6、TNF-α、IL-1β血清浓度增加,相应的mRNA及蛋白表达增强,提示自发性高血压大鼠炎症活动增强;⑶阻断p2y6受体,IL-6、TNF-α、IL-1β血清浓度、mRNA及蛋白表达均明显降低,提示p2y6受体可能是自发性高血压大鼠炎症反应的关键位点;⑷经复方钩藤降压片治疗后,IL-6、TNF-α、IL-1β血清浓度、mRNA及蛋白表达均降低,提示复方钩藤降压片一定程度上能阻断p2y6受体的表达,且与西药缬沙坦表现出协同作用。结论复方钩藤降压片一定程度上能阻断p2y6受体的表达,从而降低SHR的慢性炎症水平。

Tribological properties of electroless Ni-p-SiC composite coatings in rolling/sliding contact under boundary lubrication

International Journal of Minerals,Metallurgy and Materials 2007年第2期14卷 167-172页

作者： Shu-Hue Hsieh Shen-Jenn Hwang Ting-kan Tsai Wen-Jauh Chen Department of Materials Science and Engineering Formosa UniversityHuwei China Taipei Department of Mechanical Design Engineering Formosa UniversityHuwei China Taipei Department of Materials Engineering Pingtung University of Science and TechnologyPingtung China Taipei

Ni-p-SiC composite coatings were prepared under a given bath composition and operation parameters of electroless plating. The tribological properties of the Ni-p-SiC composite coatings after annealing at 400°C for 1 h were tested in rolling/sliding contact under boundary lubrication condition using a two-roller tribometer. The measurement contained friction coefficient, contact surface temperature, contact electrical resistance, and wear rate of the Ni-p-SiC composite coatings under various slide to roll ratios, loads, and rolling speeds. For the simultaneous examination of the effect of the chosen parameters on the tribological properties of the Ni-p-SiC composite coatings, an orthogonal regression experimental design method was used.
