Building characteristics associated with moisture related problems in 8,918 Swedish dwellings

Moisture problems in buildings have in a number of studies been shown to increase the risk for respiratory symptoms. The study Dampness in Buildings and Health (DBH) was initiated with the aim to identify health relevant exposures related to dampness in buildings. A questionnaire study about home environment with a focus on dampness problems and health was conducted in one county of Sweden (8,918 homes, response rate 79%). Building characteristics that were associated with one or more of the dampness indicators were for single-family houses, older houses, flat-roofed houses built in the 1960s and 1970s, houses with a concrete slab on the ground that were built before 1983. Moreover, tenancy and earlier renovation due to mould or moisture problems was strongly associated with dampness. A perception of dry air was associated with window-pane condensation, e.g. humid indoor air.     

湿润烧伤膏联合乳酸依沙吖啶湿敷在高龄患者慢性伤口中的应用

慢性伤口是指愈合时限延长，不能正常自愈，而需借助外力才能愈合的伤口，多发于长期卧床、身体状况较差的高龄患者。伤口迁延不愈，严重影响了患者的生活质量。     

论细菌病毒湿热交换呼吸通路过滤器HMEF的选择使用

在手术室环境中，充满潜在的病原体和感染源。已有研究显示。与普通人群相比，医护人员．尤其是呼吸系统的医疗人员。有较高的气道反应性疾病或肺结核。本文拟寻找危险因子的源头，并探讨降低其对患者和医护人员危险性的方法。 使用细菌病毒湿热交换呼吸通路过滤器能降低患者感染的危险性．从而也可能降低医护人员的危险性。

Effects of moisture on the pressing of pharmaceutical powders

The effects of moisture on the rheological and elastic-plastic characteristics of compressible powders and the qualitative characteristics of tablets of aspartame-containing sweetener were studied. Theoretical and experimental studies identified the need for additional stages of moistening tableting material in pressing techniques.

Preformulation Studies Involving Moisture Uptake in Solid Dosage Forms

The rates of moisture sorption and the resultant effect on stability of a moisture-sensitive drug blended or formulated with different components are addressed. Total moisture increase was determined by weight gain, and change in mobile water level by water activity measurements. Equilibrium relative humidity is a useful tool in predicting the stability of a moisture-sensitive drug in solid dosage forms. Since immobile water is perceived not to react chemically, the amount of mobile water rather than total water is the critical parameter in degradation reactions involving hydrolysis. Materials that have a high capacity for binding water equilibrate more slowly to higher levels of mobile water and consequently show greater chemical compatibility with a moisture-sensitive drug than materials with lower binding capacities for water.     

不同含水量打捆贮藏对苜蓿干草营养组成和产量的影响

试验研究苜蓿干草在不同水分条件下打捆对苜蓿草产量和粗蛋白产量的影响.结果表明:随着打捆前含水量的逐渐下降,茎叶比增加,叶片损失率增大,对于茎叶未经压裂的苜蓿,其含水量与茎叶比成一元线性相关;茎秆压裂后,其茎叶比与含水量之间的关系呈指数曲线的变化趋势.采用小捆型、高水分打捆贮藏,产草量、干物质和粗蛋白含量分别提高2025kg/ha,1140kgha和247kg/ha.     

Damage of cells by cryopreservation

Reproducible and reliable cryopreservation of blood cells by freeze-drying is a difficult goal to achieve. During the freeze-drying process of cells, their cell membrane or macromolecular contents are susceptible to damage. In this paper, the general process of freeze-drying as a means to achieve cryopreservation is described.In order to guarantee reproducible and reliable cryopreservation by freeze-drying, it is essential to: (a) recognise the physicochemical and technical parameters which affect the quality/activity of freeze-dried blood cells and constituents and (b) have knowledge of the quantitative interrelationships between these parameters.To ensure an optimal process it is necessary for instrumentation to be supplemented with computer control and vacuum lock sampling. In the preservation of structural and functional integrity of cells, residual water left after freeze-drying is crucial. Using curves relating activity to residual moisture content, an optimum can often be found.     

湿热交换过滤器预防术中病人低体温的临床研究

目的：探讨湿热交换过滤器（heat and moisture exchanger and filter,HMEF）预防术中全麻病人低体温的临床应用价值。方法：择期颅脑手术的成年病人60例，随机分为A、B两组，每组30例。置入直肠温度探测头接Datex Ⅱ型多功能监测仪持续监测体温。观察组（A组）在气管导管与呼吸回路间安置HMEF，对照组（B组）则不放置。将两组间体温的变化进行比较。结果：A组在诱导后、术中于术毕体温也有下降，但组间各期比较无显著差异（P＞0．05）。B组在诱导后60分钟时体温下降最为明显,为2．6℃，与A组（1．4℃）同期比较有非常显著意义（P＜0．01）。术毕寒战发生率两组间相比也有显著差异（P＜0．05）。结论：使用湿热交换过程过滤器的预防术中低体温的作用。
