    Notes: Summary Ultrastructural studies of the middle ear mucosa appear to be of significant value in better understanding the pathology of otitis media with effusion (OME). Our present study was undertaken in order to take advantage of the use of electron microscopy in investigating all areas of the middle ear mucosa. Tissues studied were obtained from the fresh postmortem temporal bones of three patients with OME and terminal head and neck malignancies. In the mucoid type of effusion (cases 1 and 2), goblet cells were seen to proliferate and secretory activity was greatly enhanced. In contrast, there was no evidence of secretory cell proliferation in the serous type of effusion. It was noteworthy that accumulated fluid was not homogeneous in the same ear, as exemplified by case 1, in which both mucoid and serous effusions were present. This occurrence was possibly the result of topographic diversity involving the secretory activity of the middle ear.

    Mitosis in the dermatophyteMicrosporum canis as revealed by freeze substitution electron microscopy (1985)
    Springer
    Protoplasma 129 (1985), S. 198-213 
    Details
    ISSN: 1615-6102

    Notes: Summary Mitosis in the dermatophyteMicrosporum canis was studied by freeze substitution and electron microscopy, and analyzed by three dimensional reconstruction from serial sections of the mitotic nuclei. The interphase nucleus has associated nucleus-associated organelle (NAO) on a portion of the outer surface of the nuclear envelope, subjacent to which there was dense intranuclear material. The NAO divided and separated on the envelope, and a spindle was formed. The spindle was composed mostly of microtubules extended between opposite NAOs. Pairing of kinetochores was observed in the spindle from an early stage of development, when chromosomes were not so condensed, and remained unchanged while chromosome condensation proceeded until metaphase. Before the completion of nuclear division, daughter nuclei were connected by a narrow spindle channel, and then the nucleolus, whose structure underwent minimal change during mitosis, was eliminated into the cytoplasm.

    Quantitative surface chemical analysis of Au—Cu alloys with aes (1988)

    Notes: The Japanese VAMAS-SCA working group is composed of 19 institutes. Three kinds of Au-Cu alloys (Au25 at%-Cu75 at%, Au50 at%-Cu50 at%, Au75 at%-Cu25 at%) were prepared, and these specimens were distributed to the members of Japanese VAMAS-SCA working group and Auger peak amplitude ratios were measured to clarify the correlation factor of different types of spectrometers. The comparison was carried out by using the relative sensitivity factor for Au and Cu. The relative sensitivity factor for lower energy varied from spectrometer to spectrometer, but that for higher energy did not vary so much. Therefore, to carry out the inter-laboratory comparison of the data, the transfer of the data of peak amplitude at higher energy should be recommended.
