    Superoxide dismutase from Mycobacterium species, strain Takeo (1976)

    Notes: Abstract Superoxide dismutase from Mycobacterium species, strain Takeo, has been purified to homogeneity as judged by disc gel electrophoresis and ultracentrifugation. The enzyme was found to have a molecular weight of approximately 61 500 by sedimentation equilibrium and to contain manganese by atomic absorption and electron spin resonance spectra. The amino acid composition was also determined. The enzyme was considerably stable to the treatment with sodium dodecyl sulfate; unless incubating at 80°C for 2 min, it was not completely dissociated into the subunits. The molecular weight of the subunit was found to be approximately 21 000. Antibodies against the superoxide dismutase were produced by immunization of rabbits with the enzyme, and the γ-globulin fraction was purified. Superoxide dismutase preparations obtained from various species of mycobacteria and nocardia cross-reacted to different degrees with these antibodies on the Ouchterlony double diffusion plates. Comparative immunological studies indicated that strain Takeo might be most closely related to Myobacterium smegmatis among species of mycobacteria and nocardia tested. The antibodies against superoxide dismutase may be used as a valuable tool for the classification of mycobacteria.

    Effects of castration and androgen-substitution on the morphology of the epididymal epithelium of the Japanese monkey, Macacus fuscatus, as revealed by scanning electron microscopy (1976)

    Notes: Summary The caput epididymidis from castrated and androgen-supplemented, castrated Japanese monkeys was observed with the scanning electron microscope. The experimental findings were compared with the normal structures in control animals. The epididymal lumen of control animals was lined by a tall, pseudostratified columnar epithelium possessing long, slender stereocilia which were densely arranged in a tuft-like form. After castration, the epididymal epithelium was decreased in height to one-fifth of controls. The stereocilia were also considerably reduced in length and in number, resulting in a flattened epithelial surface with polygonal boundaries. Frequent projection of a long, single cilium from an epithelial cell into the lumen was also a prominent feature in the epididymal ducts of the castrated animals. Administration of testosterone to the castrated animals resulted in almost complete recovery of the epididymal epithelium as well as regeneration of the stereocilia which regained a tuft-like arrangement.

    Target velocity signals of visual tracking in vermal Purkinje cells of the monkey (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-08-17
    Description: Discharges of Purkinje cells were recorded from the vermis, lobules VI and VII, of a monkey trained to track a visual target. When the monkey tracked a sinusoidally oscillating target, cellular activity changes in phase with the velocity signal of the eye movement. When the monkey fixated a stationary point, almost identical modulation in activity occurred, reflecting the velocity signal of the motion of the retinal image of the target. The data suggest that the vermis participates in the control of smooth pursuit eye movements by providing the oculomotor system with the actual target velocity information which is the sum of eye velocity and retinal image velocity signals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kase, M -- Noda, H -- Suzuki, D A -- Miller, D C -- New York, N.Y. -- Science. 1979 Aug 17;205(4407):717-20.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/111350" target="_blank"〉PubMed〈/a〉
