甲基苯丙胺和乙醇在染毒大鼠体内联用的实验研究

目的研究甲基苯丙胺（MA）和乙醇联合应用在急性、亚急性染毒大鼠体内的情况。方法以MA1.0 mg/kg剂量对慢性自由饮酒大鼠多次腹腔注射,分别建立急性、亚急性染毒大鼠模型;处死后即时检测血中乙醇浓度、体液和组织样品中MA的浓度。结果多次注入MA药后,亚急性中毒大鼠体内的MA浓度高于急性中毒大鼠;急性和亚急性联合中毒大鼠体内MA浓度均高于急性和亚急性单一药物组。结论无论是否联用乙醇,14d内增加注射次数会在大鼠体内产生不同程度的MA残留;与乙醇联用可加速MA在大鼠体内的吸收,其药物浓度的升高程度随生物样品不同存在差异。     

重伤家兔体内Cu及代谢酶变化与MOF及死亡关系

目的探讨兔重伤后机体内铜（Cu）含量及其代谢酶铜锌超氧化物歧化酶（Cu/Zn-SOD）、细胞色素c氧化酶（CCO）活性变化与继发性多器官衰竭（MOF）及死亡的关系。方法参照国际通用的创伤程度量化评分标准（ISS）,建立致MOF的家兔重伤模型,检测伤后不同时段血清及组织Cu含量与Cu/Zn-SOD和CCO的活性,分析其变化规律与继发MOF及死亡的关系。结果①重伤组家兔（包括死亡组家兔）血清Cu含量在伤后12h显著下降,36h后逐步回复;脑、心、肺组织中Cu含量伤后下降,肝脏组织Cu含量于伤后12h显著升高,36h后回落。伤后死亡组家兔脑、心、肺、肝Cu含量均较对照组降低,其中脑、肝组织Cu含量下降显著。②重伤组家兔血清Cu/Zn-SOD活性伤后12h下降3,6h之后呈升高的趋势,肝脏组织中的Cu/Zn-SOD活性伤后持续显著升高。③重伤后家兔（包括死亡组家兔）大脑皮质、心、肝CCO活性变化不明显,但脑干组织CCO活性显著升高。伤后死亡组家兔脑、心、肺、肝等器官的大体及组织学呈MOF改变。结论严重创伤可引发兔血清和组织Cu水平及Cu/Zn-SOD、CCO活性变化,这些变化可能与继发多器官衰竭和死亡相关。

‘The sleep has been rubbed from their eyes’: social citizenship and the reproduction of local hierarchies in rural Hungary and Romania

In this paper, we make three interrelated points. First, while much of the recent literature on new forms of citizenship has focused on the diversity of large cities and new forms of migration, we seek to establish rural sites as important arenas for negotiating citizenship. We stress that far from being homogeneous, villages in their struggles over belonging are affected by long-standing diversity as well as global discourses. Second, we seek to complicate the interpretation of the demise of socialism as a radical break manifested in a diminished role of the state. We show that if the central state retreats, local state actors may gain in importance for local negotiations of citizenship. Third, we explore how the local state actors sometimes use their new powers over social rights to recreate boundaries of belonging through public performances tied to the administration of these rights. We go on to explore the normative basis for these performances and indicate that membership is still based on a contribution of work to the common good. This can best be conceptualised as a shifting continuity rather than a sharp break after 1989.     

Dual citizenship and theories of democracy

Dual/multiple citizenship has become a widespread phenomenon in many parts of the world. This acceptance or tolerance of overlapping memberships in political communities represents an important element in the ongoing readjustment of the relationship between citizens and political communities in democratic systems. This article has two goals and parts. First, it evaluates dual citizenship from the perspective of five normative theories of democracy. Liberal and republican as well as multicultural and deliberative understandings of democracy deliver a broad spectrum of arguments in favour of dual citizenship. Only communitarians fear that dual citizenship endangers national democracies. Nevertheless, empirical evidence and national policies largely contradict these fears. The second part of the article reverses the perspective and shows that most theories of democracy do not only legitimate and facilitate the acceptance of dual citizenship – the phenomenon of multiple citizenships induces innovation in democratic theory in turn. A second look at the relationship between dual citizenship and theories of democracy reveals that dual citizenship stimulates refinements, expansions and reconceptualisations of these theories for a transnationalising world.
