Accumulation of toxic metals (Pb and Cd) in the sea urchin Diadema aff. antillarum Philippi, 1845, in an oceanic island (Tenerife,Canary Islands)

This document shows the results obtained from a study on the concentration of toxic heavy metals in the internal tissue and exoskeleton of sea urchins, collected from their natural habitat. The levels of lead and cadmium were measured by Graphite Furnace Atomic Absorption Spectrometry. The mean concentrations of lead and cadmium in the internal tissue were 304.04 and 260.54 μg/kg respectively, whereas in the shell they were 185.02 and 142.48 μg/kg. We also performed a statistical analysis of the differences in the distribution of metals between their exoskeleton and their internal content, a correlation study of the metal content in internal tissue and shell and sampling areas, and a correlation study between the metal content and sample size. Since the sea urchin Diadema antillarum presents a wide range of variation in metal content, this study suggests that this species is an excellent bioindicator of heavy metal contamination. © 2009 Wiley Periodicals, Inc.

体外细胞培养检验“方证对应”关系的方法学研究

目的通过在体外细胞培养中加入中药复方粗提制剂对具有典型的中医证型的肺癌患者的外周血淋巴细胞NK活性的影响，探索能否在体外实验中反映“方证对应”关系。方法以水煎醇沉法制备两种中药复方（益气养阴和健脾化痰）的粗提制剂，取具有典型的中医证型（气阴两虚或脾虚痰湿证型）的肺癌患者的外周血淋巴细胞，将同一个患者的标本分为四个体外实验组，即空白对照组，中药5mg／ml组及10mg／ml组，自细胞介素2（250^u/ml，阳性对照）组。按“辨证论治”原则加入相应的中药复方制剂。体外培养22h或94h，以MTT法检测各组的NK活性。结果无论培养22h或94h，中药组的NK活性与对照组比较皆无显著性差异（P〉0．05），而白细胞介素2（阳性对照）组的NK括性均明显升高（P〈0．05）。结论两种中药复方制剂都未能在体外反应出“方证对应”的效果，说明中药粗提制剂直接用于体外细胞培养，其结果的可靠性差。     

原发性高尿酸血症肾病的中西医治疗探讨

既往认为高尿酸血症肾病是西方国家的一种常见病,在中国少见。近年来,由于经济情况好转,饮食结构的变化,蛋白质及富含嘌呤成分的食物摄入量增加,中国发病率有增高的趋势。因此文章旨在通过探讨原发性高尿酸血症肾病的诊断及其中西医治疗方法,希望能够对临床及时正确的诊断和恰当周全的治疗该病提供一定的指导。     

Culturable and nonculturable bacterial symbionts in the toxic benthic dinoflagellate Ostreopsis lenticularis.

The toxic benthic dinoflagellate Ostreopsis lenticularis hosts a variety of symbiont bacterial flora. Laboratory cultured Ostreopsis clones require the presence of symbiotic Pseudomonas/Alteromonas bacterial strains for growth and toxicity development. Three culturable bacterial strains associated with Ostreopsis were identified as Pseudomonas/Alteromonas strain 1, Pseudomonas/Alteromonas strain 2 and Acinetobacter. Denaturing gradient gel electrophoresis (DGGE) analyses of extracted Ostreopsis associated bacterial DNAs indicated that there were three culturable and four non-culturable associated bacterial strains. The results presented here are the first report of the presence of unculturable bacterial symbionts in a toxic benthic dinoflagellate. Ostreopsis lost toxicity when exposed to elevated temperatures in the field and laboratory culture and subsequently recovered toxicity at reduced temperatures. Ostreopsis associated culturable Pseudomonas/Alteromonas bacterial strains were significantly reduced in dinoflagellate cultures exposed to elevated temperatures. The decreased toxicity of O. lenticularis exposed to elevated temperatures and their subsequent recovery of toxicity in periods of reduced thermal stress may have resulted from the effects of elevated temperature on the spectrum of culturable and unculturable bacterial species interacting with their Ostreopsis host.

To market! To market! A new dawn for community care?

The public sector in Britain has been subjected to over a decade of major reform aimed at breaking up public service monopolies, at containing costs while at the same time opening services up to greater consumer choice. Health and social services have not been exempt from this revolution in the organization and management of public sector services. The long-standing policy of care in the community is being subjected to market principles and the introduction of a ‘contract culture’ very similar to the NHS reforms introduced in 1991. This paper reviews the origins of these developments in the doctrines of ‘new public management’, a movement which has proved attractive to policy-makers in many countries. Local authority social services departments have been identified as the lead agency for the development of a mixed economy of care following a review of community care policy by the government's health adviser, Sir Roy Griffiths, and a subsequent white paper. This paper examines the limited empirical evidence available on how managers and providers are meeting the challenge bestowed upon them, and concludes that most authorities are moving ahead cautiously if at all. Only a handful of authorities studied have embraced the reforms with any degree of enthusiasm. The paper concludes with an assessment of the reforms from two perspectives: a pessimistic one and an optimistic one. There are many worrying features of the reforms, not least among these being a lack of clarity over their intended purpose. Tensions and contradictions are plentiful, which places in jeopardy the certainty of the reforms in becoming user led rather than provider driven. A more optimistic scenario is that the changes are leading to a loosening up of services and practices which have often suffered from sclerotic tendencies, paternalism and sometimes complacency. If the reform process is skilfully handled and not rushed and if the ends are clearly established and communicated then users and carers could prove to be the principal beneficiaries.     

Health policy, epidemiology and power: the interest web

The relation between epidemiological research results and policy-making is reviewed. Apparently, traditional models of policy-making(incrementalism, mixed scanning synoptic planning) do not explainwhy research findings are hardly used in policy-making procedures. It is suggested that this phenomenon is related to three determinantsof policy-making: (i) a bias stemming from sets of causal, finaland normative assumptions and presuppositions; (ii) interestwebs of groups in certain domains; and (iii) the power of organizationsto monitor and communicate. The conclusion is that epidemiologistsshould engage in the policy-making process more consciouslyand conscientiously.     

固体硅胶隆鼻术后感染排异的原因与预防探讨

感染及排异是固体硅胶隆鼻术较为严重的并发症。其发生原因主要在于手术适应证掌握不当；硅胶假体的质量不过关，假体的修雕成形不佳，假体消毒处理不严；手术操作及术后处理欠妥等。提出了加强术前体检及适应证的掌握，选择质量过关的硅胶假体，努力提高术者的审美及专业技术水平，设计修雕成形出恰当的假体，并注意规范假体的消毒处理，这都可有效减少感染及排异并发症的发生。强调手术操作时尽量减少局部组织的损伤，勿剥破鼻部的皮肤及粘膜，并做好术后的处理及护理，这同样也是减少感染排异并发症的关键。
