Amacrine cells,bipolar cells and ganglion cells of the cat retina: A Golgi study

Neuronal types contributing to the inner plexiform layer of the cat retina are described based primarily on light microscopy of Golgi-impregnated retinal whole-mounts. Cells have been characterized on morphological criteria that include dendritic branching patterns, dendritic tree sizes, cell body sizes and stratification of processes in the inner plexiform layer. Nine different types of bipolar cell, 22 different types of amacrine cell and 23 different types of ganglion cell can be distinguished using one or more of these morphological criteria. The significance of the different morphological types of cells is discussed, particularly in relationship to the functional bisublamination of the cat inner plexiform layer.     

医院各区域内空气消毒效果及监测方法的探讨

目的探讨医院各区域内空气消毒效果及监测、培养所需时间.方法对3496份消毒后空气采用"平板暴露法”进行监测.第一组848份采样时平板暴露15min、置35C温箱培养48h,第二组2648份采样平板暴露5min、培养24h.结果第一组检测无菌生长率为2.6%、阳性检出率为97.4%、合格率为83.3%;第二组无菌生长率为l7.5%.阳性检出率为82.5%,合格率为88.4%.结论根据尘粒(1～10μ粒径)自然下降规律和所带细菌受损后修复需要时间,我们认为采用"平板暴露法”监测消毒后空气时以暴露15min培养48h为好.     

Two Way Prayer: A Lost Tool for Practicing the 11th Step

Two Way Prayer formed an essential part of Oxford Group and early Alcoholics Anonymous (AA) spiritual practices. Pioneer AA members considered it more essential for recovery than attendance at meetings; however, it was gradually lost as a component of contemporary 12-Step programs. The article gives an overview of its history and provides a model for a more contemporary form of its practice. Initial evaluation suggests promising outcomes among a sampling of youth and adults engaged in a peer-support group for drug and alcohol recovery. The article includes a discussion of its use with individuals not having a religious conception of spirituality.
