    Notes: Summary An autopsy case of human T lymphotropic virus I-associated myelopathy (HAM) of a duration of 28 years in a 61-year-old man with serological confirmation of HTLV-I infection was reported. The spinal cord was grossly atrophic. There was severe symmetrical degeneration of the lateral funiculi, particularly of the bilateral pyramidal tracts, involving all levels of the spinal cord, but anterior horn cells were relatively well preserved. In the most severely damaged middle and lower thoracic segments, the white matter degeneration also involved the anterior funiculi. In the degenerated white matter, both the myelin and axons were equally lost and had been replaced by glial scars. Marked adventitial fibrosis was commonly seen in small parenchymal vessls in both the white and gray matter. Although there was no evidence of inflammation in the spinal cord, mild lymphocytic infiltration was occasionally observed in the subarachnoid and perivascular spaces in the brain stem, cerebellum and cerebrum. This case was considered as a burnt-out case of HAM.

    Immunohistochemical Study of Steroidogenic Enzymes in the Ovary and Placenta During Pregnancy in the Dog (1999)

    Notes: Using the immunohistochemical technique, we attempted to identify the source of secretion of steroid hormones between the mid- and late-terms of gestation in dogs by investigating steroid converting enzymes such as cholesterol side-chain cleavage enzyme (SCC), 3 β-hydroxysteroid dehydrogenase/isomerase (3 β-HSD), 17 α-hydroxylase/C17, 20lyase (c17), and aromatase in the ovaries and placenta. Aromatase positive cells were slightly confirmed in luteal cells in the mid-term of gestation (day 40), whereas, in the late-stage (day 50 and 60), the number of aromatase positive cells had increased. However, the oestrogen precursor (c-17 positive cells), could barely be identified in the marginal regions of the corpora lutea (CL) and completely disappeared in the late-stage of gestation. The androgen precursors, convertase SCC and 3 β-HSD, were confirmed in all regions of the CL during the mid-stage of gestation (day 40), showing particularly strong cell reactions in the marginal region of the CL. Yet, these positive reactions of SCC and 3 β-HSD in the marginal region of the CL disappeared in the late-stage of gestation. Moreover, it was discovered that the number of SCC and 3 β-HSD positive cells had decreased in all regions of the CL. None of the enzymes were detected in the placenta. The above results indicated that the source of oestrogen secretion in pregnant dogs is considered to be the CL, and that, compared with the mid-stage of gestation, there was an increased number of oestrogen synthesizing cells within the CL in the late-stage. However, the biosynthetic site of oestrogen precursors from the luteal cells during the late-stage of gestation is still unknown.

    Surfactant effects on heterogeneous polymer reaction: Nucleophilic substitution of poly(vinyl chloride) in water (1973)

    Description / Table of Contents: Die Reaktionen von Polyvinylchlorid (PVC) mit einigen nucleophilen Agentien wie Azid-, Thiophenoxid-, und Dithiocarbamat-Ionen kommen in Wasser nicht zustande. Die heterogenen Reaktionen werden von kationenoberflächenaktiven Substanzen wirksam katalysiert. Harnstoff und Methylalkohol, die hydrophobe Bindungen zerbrechen, inhibieren die Reaktion. Auf Grund experimenteller Daten wird angenommen, daß die kationenoberflächenaktiven Substanzen von dem in Wasser suspendierten pulvrigen PVC adsorbiert werden und daß die positive Ladung die nucleophilen Agentien heranbringt.
    Notes: The reactions of poly(vinyl chloride) (PVC) with some nucleophiles such as azide, thiophenoxide and dithiocarbamate ions do not take place in water. These heterogeneous reactions are remarkably catalyzed by cationic surfactants. Urea and methanol which destroy hydrophobic bondings inhibit the reaction. On the basis of the experimental data it was assumed that the cationic surfactants are adsorbed on the surface of the suspended PVC powder and that the positive charges attract the nucleophiles.
