The Sick Building Syndrome as a subjective perception-theoretical approach and assessment methods

The SBS is characterised by irritations of mucosa, vegetative complaints such as headache and fatigue as well as mental health impairment, depression and irritability (WHO definition). Since well-being is a subjective perception, the individual self report is mandatory. In the ProKlimA project a modular questionnaire was developed in which SBS symptoms, general aspects of well-being and function as well as psychosocial characteristics were included in a modular fashion. Assessment included sensory irritation (SI list), psychosocial characteristics (POMS) and bodily complaints, assessed with a standard German complaint list (BL). In addition the individual indoor-air perception, stress reactions, the perceived work-environment, health locus of control, life satisfaction and work related use were assessed. Analysis of the questionnaire filled out by 4596 employees at the first measure point showed a high consistency of responses. Psychometric testing showed a high reliability and acceptable validity of the questionnaire. The results suggests that well-being within the SBS complex can be assessed in a methodological way and that the developed questionnaire can be used to assess SBS symptomatology as well as psychosocial determinants also in further SBS studies.     

Flagellate and non-flagellate Proteus mirabilis in the development of experimental urinary tract infection

Three isolates of Proteus mirabilis from symptomatic human urinary tract infections (UTI) were tested for their ability to cause renal infection in mice. All three strains were fimbriated as tested by hemagglutination. One of the strains, Pr 988, did not possess flagella, whereas the other two did and were capable of swarming on solid rich media. We compared the capacity of these strains to infect mice in both the ascending and hematogenous mouse UTI models. Infection was assessed by counting viable bacteria in kidney and bladder homogenates in ascending UTI or by the presence of abscesses in the hematogenously inoculated mice. All three strains were able to infect mice in both UTI models. These results suggest that flagella are not absolutely necessary for virulence in these experimental models.     

胶束毛细管电泳测定豆粕及发酵豆粕中大豆异黄酮含量

 目的 建立测定豆粕及发酵豆粕中大豆异黄酮含量的毛细管电泳方法。方法 采用胶束毛细管电泳法(MECC),未涂层弹性石英毛细管(50 μm×60 cm,50 cm);压力进样,压力：3.0×103 Pa;进样时间：5 s;分离电压：17 kV;柱温：20 ℃;检测波长：254 nm;运行缓冲液：15 mmol·L-1 十二烷基硫酸钠、5%甲醇的10 mmol·L-1硼砂溶液(pH 9.4)。结果 测得6种大豆异黄酮组分在24 min内能完全分离并具有良好的线性关系;平均加样回收率（n=5）在 99.6%~103.5%之间,RSD为1.8%~2.3%。结论 方法准确、可靠、经济、操作简便,适合于豆粕及发酵豆粕中大豆异黄酮含量的测定。     

经支气管镜介入诊疗支气管结核探讨

目的探讨支气管镜对支气管结核的诊疗价值。方法分析经病理或刷检涂片、痰细菌学检查证实的113例支气管结核的临床表现、支气管镜检查所见,以及经支气管镜介入治疗的不同方法,探讨治疗效果。结果本组平均年龄37.3岁,男女比例为1:2.05。在支气管镜下显示左侧多于右侧,镜下具有多形态,多部位特点。炎症浸润型32例(28.3%),溃疡或干酪坏死型41例(36.3%),肉芽增殖型28例(24.8%),瘢痕狭窄型11例(9.7%),管壁软化型1例,(0.9%)。不同的介入治疗方法治疗不同类型的支气管结核均获得良好疗效。结论支气管镜检查是诊断支气管结核的主要手段,支气管镜介入治疗是有效的局部治疗方法。
