制药工程专业微生物学教学改革与实践

针对制药工程专业的培养目标,对微生物学的教学内容、教学方法进行了改革,建立了＂基础＋专业＂的内容体系和多样式互动教学方法,结果表明,新的教学模式有利于培养学生的学习主动性和兴趣,取得了较好的教学效果。     

Q fever in the Mordvinian ASSR]

In the serological (CFT) examination of patients with elevated temperature for Q fever positive results were obtained in 8.2--14% of cases. The number of positive results of the CFT in rural districts was higher (16%) than in urban districts (10.2%). A considerable percentage of positive results was observed among the workers of a meat-packing plant (25%) and among persons who regularly received milk at their work as a special diet (25--39.2%). In the Mordovian ASSR the infection seemed to be transmitted mainly by the alimentary and contact ways.     

深海微生物的研究与开发

深海是全球最大的独立生态系统,其中蕴涵着丰富并且独特的微生物资源有待我们开发。对深海微生物及其所处生态系统的研究将提升我们对地球早期环境及其变化过程的认识,为研究生命起源,甚至探索域外生命或其他潜在生命形式提供新的线索。对深海微生物研究开发的历史和进展进行了概述,并对这一研究领域的前沿及影响进行了讨论。     

Global trends in research resources and scientific output in microbiology in Spain (1998-2007)

This work assesses the main features of microbiological research developed in Spain over the last decade (1998-2007), observing its changes and trends along the time and comparing them to those which have taken place in other life sciences. This analysis encompasses the entire scientific cycle: the organizations involved (basically, universities, research centers, scientific societies, and companies), resources invested (human and economic), and outputs or results obtained (journals, articles, doctoral theses, and other documents or publications). Summarizing, there is a positive trend in Spanish microbiology regarding research projects and scientific articles; the scientific output (research articles) of Spanish microbiologists ranks 6th in the world, which is higher than the ranking of Spain with respect to economic development.     

Latitudinal variations in the composition and structure of vegetation in the northwestern Tatar Strait

The pattern of the latitudinal distribution of the floristic composition and structure of the submerged vegetation cover in the western Tatar Strait (within Khabarovsk Krai) is studied using the published data and original materials. Irregularities of the floristic composition have been found within limited areas of bays in this region, where they do not form any distinct borders or gradients. In the vegetation cover, vice versa, borders and gradients have been shown to form various combinations. The specific biomasses of most of the dominant species are significantly increasing, whereas the width and depth of the vegetation belt decreases from the south to the north. Their regression lines intersect at the latitude of 50° N (Cape Syurkum). Discrete coenotic variations are manifested most clearly as well at this point, where the dominance of Saccharina japonica, observed south of the cape, changes for S. cichorioides north of it. This allows establishing the phytocoenotic border here. The revealed features correspond to the direction of the temperature gradient, as well as to the variations in topical conditions and the level of hydrodynamic load along the coast.     

Determination of natural foci of tularemia in the Tuva ASSR]

Eleven strains of tularemia causative agents were isolated in 1974 in bacteriological study of ixodes ticks Dermacentor nuttalli (13088 in all) by biotests on albino mice. Tularemia was confirmed retrospectively in two humans who contracted the disease from ondatra cadavers. Skin allergic test with tularin was used to examine 1733 residents of seven populated localities; a positive result was obtained in 2 persons. Finally, in examination of 240 sera of cattle agglutination reaction proved to be positive in 6 cases in titres of from 1:20 to 1:80. Thus, natural nidality of tularemia in Tuva was established for the first time.
