    Use of neodymium nitrate in electron microscopic histochemical demonstration of ATP-ase (1974)
    Springer
    Histochemistry and cell biology 42 (1974), S. 265-269

    Notes: Summary Neodymium nitrate has been used instead of lead nitrate in the modified Wachstein-Meisel incubation solution. Neodymium reacts easily with the anorganic phosphate groups. The rare earth metal has strong electron scattering property. It was used in 3,0 mM concentration in the incubation solution. The histochemical precipitate obtained, appeared to be selective and was well localizable. Neodymium nitrate seems to be suitable for the electron microscopic histochemical demonstration of hydrolytic enzymes.

    Localizing acethyl-serotonin transferase by electron microscopy (1975)

    Notes: Summary N-acethylserotonin, the substrate of hydroxy-indol-o-methyl-transferase (HIOMT) is being synthetized by the serotonin-acethyl-transferase. The localization of the enzyme in the pineal gland has been studied by uranyl and copper ferrocyanide methods. Both methods revealed a mitochondrial localization. The reaction precipitate was situated on the outer and inner membrane as well as in the inner compartment of the mitochondrium. Without acethyl-Co A the reaction failed to take place. Copper ferrocyanide was found more favourable than the uranyl ferrocyanide. No specific reaction, extramitochondrial precipitate occured.

    A new method for cytochemical demonstration of calcium in heart muscle (1982)
    Springer
    Histochemistry and cell biology 75 (1982), S. 425-436

    Notes: Summary The ortho-cresolphtalein complex was successfully adapted for the electron microscopic cytochemical demonstration of calcium. The reaction product is of granular nature with sufficient electron density for finer localization. Intense precipitation was found on the sarcolemma and transverse tubules and in the sarcoplasmic reticulum. Myofilaments, mitochondria and capillary endothelial cells also showed a positive reaction. The electron microprobe analysis of the precipitate proved the presence of calcium. Disturbing effects of magnesium ions were prevented by the incorporation of 8-hydroxyquinoline in the incubation medium.

    Intracisternal virus-like particles in a human pituitary adenoma (1976)
    Springer
    Journal of cancer research and clinical oncology 85 (1976), S. 111-115 
    Details

    Topics: Medicine
    Notes: Summary Electron microscopy revealed the presence of intracisternal virus-like particles in a mixed pituitary adenoma consisting of growth hormone cells and prolactin cells. The tumor was removed by surgery from a 48 year old man with a multiple endocrine adenomatosis type I syndrome. The significance of virus-like particles in the pathogenesis of pituitary adenomas remains to be elucidated.
