目的:探寻医疗微生物实验室生物安全管理以及疾病预防控制系统的建设。方法:分析当前生物安全出现的原因及预防措施,采用列举的方法,对相关体系的完善提出建议。结果:由于传染病毒具有扩散块、毒力强的特点,因此生物安全的建设逐步受到社会的重视,其中疾病控制、疾病预防系统的建设及实验室的医疗安全检测具有格外重要的意义。通过调查发现,加强二者的安全管理,必须加强五个方面的建设,即严格遵守疾病控制系统与实验室安全管理规定,对有关的实验设备进行完善与升级,对实验室病菌实验严格把控,对医疗人员、技术人员及检验人员进行定期的安全培训,对实验室废弃物进行管理。讨论:由于当前传染病毒的危害越来越严重,因此,关注生物安全,完善相关的体系建设具有十分重要的意义,国家及医疗部门需要对此给予足够的重视。 相似文献

目前,我国已有两家生物安全四级实验室和五十多家生物安全三级实验室完成建造并通过实验室认可。生物安全管理体系的技术要素和管理要素是确保高级别生物安全实验室生物安全的关键。本文探讨了高级别生物安全实验室区别于其他体系实验室(如ISO 17025检测和校准实验室与ISO 15189医学实验室)的若干个特征性管理要素,这些要素包括潜在污染的周期性评估、失活验证实验、分子诊断实验的无生物风险的阳性对照、微生物的不同封闭措施及生物安全文化。潜在污染的周期性评估与失活验证实验是高级别生物安全实验室日常管理的强制性措施。分子诊断实验的无生物风险的阳性对照与微生物的不同封闭措施应用于微生物实验(尤其是病毒学实验)从而降低暴露风险。生物安全文化应全面施行,以预防生物安全事件的再次发生。 相似文献

Although the importance of the endosperm as a food store inmany angiosperm seeds is well known, its significance duringearly embryogenesis has been neglected. In many interspecifichybrids, and in some other situations, embryos do not developfully and abort. It has often been stated that this is causedby the endosperm failing to conduct sufficient nutrients tothe embryo, but seldom has it been suggested that the endospermactively controls most of the early stages of morphogenesisof the embryo. Information gleaned from a broad survey of theliterature, combined with additional evidence presented here,obtained fromSolanum incanumand interspecific hybrids, indicatethat the endosperm is dynamic and very active in regulatingearly embryo development. This requires highly integrated geneticcontrol of rapidly changing metabolism in the endosperm. Ininterspecific hybrids, lack of coordination may cause unbalancedproduction of growth regulating substances by the endospermand hence abortion of the embryo, or even unregulated productionof nucleases and proteases resulting firstly in autolysis ofthe endosperm and then digestion of the embryo. The endospermmay thus serve to detect inappropriate hybridization of speciesor ploidy levels and so prevent waste of resources by producingseeds that would result in sterile hybrids or unthrifty subsequentgenerations.

For most organisms oxygen is essential fo life. When oxygen levels drop below those required to maintain the minimum physiological oxygen requirement of an organism or tissue it is termed hypoxia. To counter act possible deleterious effects of such a state, an immediate molecular response is initiated causing adaptation responses aimed at cell survival. This response is mediated by the hypoxia-inducible factor-1 (HIF-1), which is a heterodimer consisting of an alpha- and a beta-subunit. HIF-1 alpha protein is stabilized under hypoxic conditions and therefore confers selectivity to this response. Hypoxia is characteristic of tumors, mainly because of impaired blood supply resulting from abnormal growth. Over the past few years enormous progress has been made in the attempt to understand how the activation of the physiological response to hypoxia influences neoplastic growth. In this review some aspects of HIF-1 pathway activation in tumors and the consequences for pathophysiology and treatment of neoplasia are discussed. 相似文献

Studies of human constitution and mental features are traditionally among the main concepts of anthropological research. In
this research, we attempted to discover connections between morphological and constitutional features and self-esteem in children
and adolescents. Such a connection was discovered in some studied age groups. The obtained results could serve as a basis
for further studies in this field. 相似文献
