An Experimental Study on the Anticoagulant Effect of the Extract from Tick on Rabbits and Human Plasma

通过体外试验,观察牛蜱粗提物对家兔及人血浆的抗凝血效果.通过测定与比较加入牛蜱粗提物与未加牛蜱粗提物的兔血浆和人血浆的血浆复钙时间(RT)、凝血酶原时间(PT)、白陶土部分凝血酶激活时间(KPTT),发现牛蜱粗提物能使兔血浆及人血浆RT、PT、KPTT均显著延长,且其作用随着牛蜱粗提物用量的增大而增强.实验结果显示牛蜱粗提物具有明显的抗凝作用.Ticks are common ectoparasites of human and domestic animal and they are regarded as important vectors of zoonose disease due to their ability of transmitting a lot of pathogens to animal and people.As ticks obtain their nutrition from host by sucking their blood,their saliva must contain components to prevent the coagulation of the host blood. To investigate the anticoagulant effect of the extract from the tick on rabbits and human plasma,recalcification time(RT),prothrombin time(PT)and activated kaolin partial thromboplastin time(KPTT) were detected in vitro following the tick extract being added into the plasma of rabbits and human.Compare to the control group in the experiments,the results of RT,PT and KPTT of the test group which the tick extract was added in were shown prolonged significantly.And the anticoagulant effects were dosage dependent.The data showed that the tick extract has prominent anticoagulant effects on rabbits and human plasma.福建省青年科技人才创新项目(2002J051)资

Density and biomass of the meiofauna in the eastern sea of Xiamen and Anhai Bay

2007年6月对厦门东海域5个站位和晋江安海湾4个站位进行了小型底栖动物调查,分析了小型底栖动物的类群组成、密度和生物量.结果表明,从这两个海域样品中共鉴定出12个小型底栖动物类群,厦门东海域和安海湾自由生活海洋线虫分别占总数量的84.56%和98.19%.生物量组成和密度组成不同,厦门东海域多毛类(37.80%)、海洋线虫(33.32%)和底栖桡足类(18.64%)共同组成了小型底栖动物的生物量优势类群;安海湾生物量优势类群是由海洋线虫(67.64%)和多毛类(30.46%)组成.厦门东海域小型底栖动物的平均密度为22.67±10.21 Ind/CM2,平均生物量为23.01±10.41μg/CM2;安海湾的平均密度为31.48±45.58 Ind/CM2,平均生物量为18.28±25.69μg/CM2.The meiofauna was investigated in the eastern sea of Xiamen and Anhai Bay in July 2007.The results showed that the meiofauna density in the eastern sea of Xiamen was 22.67±10.21 ind/cm2,the average biomass was 23.01±10.41 μg/cm2.The density in Anhai Bay was 31.48±45.58 ind/cm2 and the average biomass was 18.28±25.69 μg/cm2.A total of 12 groups were recognized in the study and free-living marine nematode was the most dominant group accounting for 84.56% in the eastern sea of Xiamen and 98.19% in Anhai Bay,respectively.Based on the biomass,polychaetes(37.80%),marine nematodes(33.32%) and benthic copepods(18.64%) were the most important groups in the eastern sea of Xiamen while they were marine nematodes(67.64%) and polychaetes(30.46%) in Anhai Bay.福建省908专项资助项目(FJ908-01-01-HS);国家重点基础研究发展规划项目(2005CB422305);国家海洋局第三海洋研究所基本科研业务费专项资金资助项目(海三科2009030

Electrochemical Corrosion Behavior of Copper Clad Laminate in NaC1 Solution

应用线性极化、循环伏安(CV)及电化学阻抗谱(EIS)等电化学方法对覆铜板(CCL)和纯铜的腐蚀电化学行为进行了研究和比较.结果表明,覆铜板的耐蚀性弱于纯铜,其阳极溶解过程与纯铜有所不同;在较低电位下,CCL以铜的氯化络合物的形式溶解,CuCl_2~-的扩散为该过程的控制步骤;随着电位的升高,腐蚀产物CuCl在电极表面形成疏松多孔的膜,Cl~-在膜中的传输成为溶解过程的控制步骤.电极表面CuCl膜的消长过程是产生感抗弧的主要原因.Comparing with pure copper,the corrosion behavior of copper clad laminate(CCL)in NaCl solution was studied by using linear polarization,cyclic voltammetry(CV)and electrochemical impedance spectroscopy(EIS).It was shown that CCL had a different corrosion behavior and showed a lower corrosion resistance compared with the pure copper.At low polarization potential,CCL dissolves through the formation of CuCl_2~-,which may be a determined step in the anodic process.And when the polarization potential increased,a porous film containing CuCl formed on the CCL surface,and the transportation of Cl~- in the film became the controlling step in the corrosion process.An inductive loop at low frequency was observed in the EIS measurement,which was attributed to the modulation of CuCl film due to the competition between dissolution and growth processes on CCL surface.国家自然科学基金(50571085)资助项
