    Ultrastructure of muscle in Stiff-man syndrome (1974)
    Springer
    Virchows Archiv 362 (1974), S. 207-221

    Notes: Summary Ultrastructural changes observed in a muscle biopsy from a patient suffering with “Stiff-man” syndrome are described. In addition to nonspecific degenerative and regenerative changes in the myofibers, the site of maximal pathology seems to be the myoneural junction, with mainly hypertrophic and hyperplastic changes of the motor end plates. The possible pathophysiological factors causing these inductive changes are discussed.

    Effect of specimen preparation on intracellular myocardial calcium (1974)
    Springer
    Histochemistry and cell biology 38 (1974), S. 143-153

    Notes: Summary Calcium concentration and intracellular localization were investigated using the electron microscopic X-ray analyser (EMMA-4) in preparations of dog myocardial tissues fixed either in glutaraldehyde, osmium tetroxide or potassium pyroantimonate plus osmium tetroxide. Calcium could be detected with all the fixatives, but at varying efficiency. Glutaraldehyde fixation showed small detectable amounts of calcium and without special localization except in the nucleus. Osmium fixation showed much higher, but still poorly localized concentrations. The pyroantimonate technique produced the highest calcium concentrations and loci of statistically significant concentrations. Preparations stained with uranyl acetate or lead citrate showed well-visualized precipitates but no detectable calcium concentrations.
