查询词典 isolated singular point

All the compounds were isolated and identified from the bituminous coals for the first time, bis(2-ethylheptyl) terephthalate and 18-ethyl-17-(hexan-2\'-yl) docosanoic acid are new compounds.Further more, a Colourless Oil Liquid, a white acerate crystals containing some alkanes, a white tabular crystals consisting of some fatty acid esters and a white powder crystals in which some fatty acids exist were isolated and analysed by GC/MS for the first time.Through this research, a study method of"classification extract of bituminous coal- separation with silica-gel and gelatin column chromatographies- identification of the isolated compounds by FTIR, GC/MS, LC/MS, 1H NMR and 13C NMR analyses"was established and proved to be a practical approach toward separable and non-destructive identification of some organic compounds in bituminous coals for coal chemistry research.

The protozoa were isolated from field animal blood, vectors, pathogenic tissue and secretions. Based on differences of the pathogen morphology, vector species, experimental infected animals, single parasite clone and parasitic tissues, protozoiasis pathogens from different areas and animals in China were isolated and the vectors and transmission mode were also determined by vector transmission trial. Sequence analysis of 18S rRNA gene was used to study the phylogeny of partial isolated protozoa.

自野外采集动物血液、传播媒介、相关组织、排泄物等，根据对病原形态鉴定、传播媒介鉴定、实验性感染易感动物、单一虫株克隆、不同致病部位等方法，对我国不同地区、不同家畜的原虫病病原进行分离，并通过媒介传播试验确定传播媒介的种类与传播方式；采用18S rRNA基因测序方法，对本实验室已分离的部分原虫进行进化关系研究。

Results MRSA strains were isolated from the burn wounds in 22 of 41 (53.7%) patients, and 5 from the nasal vestibules. Moreover,among 19 medical staffs,MRSA strains were isolated from the hands of 9 persons, but not from the nasal vestibules. From the hands in 9 of 43 lay attendants and the nasal vestibules in 2 MRSA strains were found. Thirteen MRSA strains were isolated from 193 specimens from the surrounding items.

结果 53.7％(22/41)的患者创面分离出MRSA，其中5例鼻前庭分离出MRSA；19名工作人员中，3人手分离出MRSA，工作人员鼻前庭未分离到MRSA；43例患者陪护家属中有9人手上分离出MRSA，2人鼻前庭分离出MRSA；193份环境标本共分离MRSA 13株。

Methods Five hundred and four specimens were isolated from the wounds and nasal vestibules of burn patients ,the hands and nasal vestibules of medical staffs and lay attendants and the surfaces of various equipments. From these specimens,58 strains of MRSA and 43 methicillin- sensitive staphylococcus aureus were isolated. The genome DNA of isolated MRSA strains was analyzed by repetitive DNA - sequence- based PCR analysis.
