净化液处理对豇豆采后多环芳烃(PAHs)的净化效果研究

为降低蔬菜采后体内多环芳烃(PAHs)对人体的危害风险,以豇豆为材料,利用不同浓度洗洁精、食盐、米酒、米醋、植物油及清水分别对豇豆豆荚进行浸洗,通过高效液相色谱-质谱联用法检测豇豆采后体内PAHs的含量,并筛选出豇豆体内PAHs的最佳净化方法。结果表明,米酒和米醋处理对豇豆体内PAHs的去除效果基本一致,其中米酒处理组的∑PAHs（美国环保局公布的优先监测的16种多环芳烃的含量总和）降低68.92%,米醋处理组的∑PAHs降低73.88%,且对萘、二苯并(a,h)蒽和茚并(1,2,3-c,d)芘等均有明显的去除效果;清水浸洗可有效降低豇豆体内的茚并(1,2,3-c,d)芘含量,但会使菲的含量增加;食盐处理使∑PAHs增加了77.15%,主要表现在增加了2、3环PAHs在豇豆体内的积累;植物油处理可降低个别PAHs单体含量,但会引入其他PAHs单体,同时增加∑PAHs含量。毒性当量计算结果表明,米酒能有效降低豇豆体内的PAHs毒性,同时食盐处理也使豇豆体内的PAHs毒性当量降低。米酒和米醋能有效降低豇豆体内∑PAHs和二苯并(a,h)蒽的含量及其毒性当量。

Acupuncture for general veterinary practice.

Since the International Society of Veterinary Acupuncture (IVAS) was founded in 1974, acupuncture (AP) has received greater acceptance by veterinary professionals throughout the world. This article introduces some important animal diseases that respond well to AP therapy. These include resuscitation of small animals, treatment of anoestrous gilts and sows, bovine reproductive disease, canine vertebral problems and equine backpain, etc. Conventional medicine considers these to be difficult cases to treat. Veterinarians have become more aware of the benefits of AP especially for those diseases, thanks to the efforts of experienced practitioners and scientists, and the many published reports on veterinary AP that have introduced some good indications for AP therapy in veterinary practice. Possible mechanisms behind the effectiveness of AP are discussed. This article aims to introduce veterinarians to good indications for AP to initiate their interest in the practice of AP. Although this is a rapidly expanding field, a long march must begin with one step. We wish this article to be the shoes for such a march. For more information on veterinary AP, contact IVAS , P.O. Box 1478, Longmont, CO.. 80502, USA (http://www.ivas.org), or your national veterinary acupuncture society (http://www.komvet.at/ ivadkom/vapsocs.htm).     

Genotype evaluation,muscle histopathology and ultrastructure in a Duchenne muscular dystrophy animal model

AIM: To evaluate the genotype , muscle histopathology and ultrastructure in dko mice. METHODS: Dystrophin/Utrophin-deficient double knockouts (dko) mice were obtained from university of Oxford, UK. Genotype of filial generation of heterozygote was evaluated by PCR-SSP. HE staining and fluorescent immunohistochemistry by SABC-Cy3 were used to detect striated muscle of dko mouse, and the muscle ultrastructure was observed by transmission electron microscope(TEM). RESULTS: In 112 filial generation mice, there were 28 mdx (25.0%), 26 dko (23.2%) and 58 heterozygote (51.8%), which coincided with the law of Mendelian inheritance. HE staining showed that the myocytes were not very uniform, there were phenomenon of round outline, centrally nucleated fibers, widening interspace, inflammatory cell infiltration and connective tissue proliferation in dko mice. There were no any immunofluorescent expression of dystrophin and utrophin in sarcolemma in dko mice. TEM showed sarcolemma breakage, separation and edema, and loose myofibril texture, inflammatory cell infiltration and connective tissue proliferation in dko mice. CONCLUSION: PCR-SSP is a very quick and accurate way for genotype evaluation of filial generation. The pathophysiology of dko mouse was very similar to Duchenne muscular dystrophy (DMD), and dko mouse is an ideal animal model for study of DMD clinical therapy.     

森林消防人员心理服务研究

分析了森林火灾的突发性、不可预知性、破坏性、持续性和失控性等特点,从灾难心理学的角度提出森林消防人员是森林火灾的间接受害人.森林火灾作为一种自然灾难,时森林消防人员会产生不同程度的影响,使森林消防人员产生创伤后应激障碍,需要对森林消防人员进行灾后的心理干预服务,同时对他们在日常生活学习进行心理辅导,以提高他们的心理应激能力,培养森林消防人员优秀的心理素质.     

混凝土结构表面蜂窝麻面成因及其防治措施

随着建筑业的飞速发展和科技水平的不断提高,工程对混凝土的各种性能要求越来越高,不仅要求混凝土工作性能好、强度指标高、耐久性好等,而且还要求混凝土结构表面无蜂窝麻面光洁如镜的外观,尤其是清水混凝土结构要求更为严格,为此我们必须加以防范,给予重视。
