    Histochemical, cytochemical and autoradiographic studies on the rostellum ofHymenolepis diminuta (1981)
    Springer
    Parasitology research 64 (1981), S. 335-345

    Notes: Abstract Histochemical studies on the rostellum ofHymenolepis diminuta revealed diastase-stable, protein/neutral carbohydrate-rich material localized in the rostellum tegument. The remainder of the rostellum, primarily composed of the glycogen-rich myocytons of the rostellum musculature, is protein-poor, but rich in diastase-labile, neutral and acidic carbohydrates. Ultrastructural cytochemical studies, using the periodic acid-thiocarbohydrazideosmium (PATCO) technique, indicated that the granules of the rostellar tegumental cytons and distal cytoplasm are carbohydrate-rich. Lipids are present in the rostellar myocytons but not in the tegumental cytons. Autoradiography using a pulse-labeling with [3H]leucine revealed an apical translocation of tegumental granules, but at a slower rate than had been reported for the strobilar tegument of the same organism. Neither [3H]galactose nor [3H]glucose were incorporated into the rostellar tegumental granules. The function of the secretory glycoprotein(s) produced in the rostellar tegument and its (their) possible role in the regulation of maturation and/or strobilization remain enigmatic.

    Synthesis of the intranuclear crystals in Scolopendrium vulgare (L.) SM (1981)
    Springer
    Planta 152 (1981), S. 137-144

    ISSN: 1432-2048
    Keywords: Autoradiography ; Intranuclear crystals ; Nucleus, crystolo-Protein transfer-Pteridophytes ; Scolopendrium

    Notes: Abstract Proteinaceous intranuclear crystals are found in the fern Scolopendrium vulgare. During mitosis these crystals are eliminated from the nucleus into the cytoplasm, where they are dissolved. New crystals appear in the nucleus. The site of synthesis of intranuclear crystal proteins was investigated using quantitative ultrastructural autoradiography after incubation with tritiated lysine. The results suggest a migration of cytoplasmic proteins to the nucleus, part of which would then be incorporated into the intranuclear crystals.

    Evaluation of the effects of sensory denervation on osteoblasts by 3H-proline autoradiography (1981)
    Springer
    Cell & tissue research 217 (1981), S. 569-576 
    Details
    ISSN: 1432-0878
    Keywords: Autoradiography ; 3H-proline ; Osteoblasts ; Denervation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary The inferior alveolar nerve was unilaterally resected in 30-day-old mice; other animals were unilaterally sham-operated. At 15, 30, 60, 90, or 150 days after surgery, the mice were injected with 2μCi of 3H-proline (sp. act. 1.0 Ci/mM) per g of body weight and killed 15, 30, or 60 min later. Autoradiographs were prepared from 5μm decalcified sagittal sections of mandibles and grain counts made over periosteal osteoblasts mesial to the first molar. In denervated mandibles, osteoblasts incorporated less isotope compared to controls with differences being maximal at the early intervals. These differences became attenuated with time, possibly due to an intrinsic compensatory mechanism, secondary to neurotrophic regulation.

    Bilaterally asymmetrical uptake of [14C]2-deoxyglucose by the octavo-lateralis complexes in flatfish (1981)
    Springer
    Cell & tissue research 214 (1981), S. 659-662 
    Details
    ISSN: 1432-0878
    Keywords: Vestibular system ; Postural control ; Deoxyglucose method ; Autoradiography ; Flatfish

    Topics: Biology , Medicine
    Notes: Summary [14C]2-deoxyglucose uptake by neurons located in the octavo-lateralis complex of adult flatfish is asymmetrical on the two sides of the brain. It appears that the neuronal activity on the side oriented upward is higher than that on the side of the brain facing downward. This finding may be significant with respect to the mechanisms of metamorphosis of flatfish and may account for the peculiar fact that these animals swim on one body side during adult live.
