the role of the alveolar macrophage in the clearance of bacteria from the lung.pulmonary clearance of bacteria was studied using histologic, bacteriologic, and radiotracer methods. when mice were exposed to an aerosol of p(32)-tagged staphylococcus aureus or proteus mirabilis, and the rate of disappearance of viable bacteria compared with the rate of their mechanical removal, it was found that bacterial viability declined 80 to 90 per cent in 4 hours, whereas radioactivity declined by only 14 to 20 per cent. the marked disparity in these rates indicated that mechanical rem ...196414113111

the content and relative base ratios of ribonucleic acid in amoeba.the amount and relative base ratios of ribonucleic acid (rna) in the nucleus and cytoplasm of amoeba proteus and a. dubia, and of homospecies cells obtained by nuclear transfer with a. proteus, have been determined by microelectrophoresis. in a. proteus the average amounts of rna in the nucleus and the cytoplasm were 134. micromicrograms and 2520. micromicrograms; in a. dubia the averages for the nucleus and cytoplasm were 67. micromicrograms and 1427. micromicrograms. the relative base ratio of ...196414105213
electron microscopy of mitosis in a radiosensitive giant amoeba.various aspects of the ultrastructure of the dividing nuclei in the large radiosensitive amoeba pelomyxa illinoisensis are demonstrated. evidence of nuclear envelope breakdown is presented, and membrane fragments are traced throughout metaphase to envelope reconstruction in anaphase and telophase. annuli in the nuclear envelope and its fragments are shown throughout mitosis. during metaphase and anaphase some 15 to 20 mitochondria are aligned at each end of the spindle, and are called polar mito ...196414105218
