    Notes: Summary Nitric oxide (NO) is thought to be involved in neurodegenerative processes. Concerning Parkinson's disease (PD) it remains to be elucidated, if NO contributes to pathological alterations in the striatum. The present study evaluates the post-mortem putamen of PD patients and control subjects for distribution patterns of NO-synthase containing neurons, using the NADPH-diaphorase technique. The ratio of positively stained neurons and the total number of cells (control: 1,120±69 per mm2, n=5; PD: 575±164mm2, n=5) shows striking differences between controls and PD patients. Our findings give reason to conclude that NADPH-diaphorase positive structures may have pathogenetic importance in degenerative processes in PD putamen.

    Description / Table of Contents: On the Structure of a New Modification of Phosphorus Sulfide P4S9A new modification of P4S9 is formed by the reaction of phosphorus pentasulfide with isopropanol in a molar ratio 1:4. The pure substance can be isolated by repeated fractional crystallization from CS2. This modification crystallizes in the monoclinic space group P21/n with a = 855.5 pm, b = 1263.7 pm, c = 1245.3 pm, β = 104.94°, Z = 4. Normally the P4S9 I crystallizes from its melts, only by shorttime heating the cubic modification (P4S9 II) is yielded.
    Notes: Bei der Reaktion von Phosphor(V)-sulfid mit Isopropanol im Molverhältnis 1:4 bildet sich eine neue Modifikation des P4S9. Die reine Substanz läßt sich durch mehrfache fraktionierte Kristallisation aus CS2 isolieren. Diese Modifikation kristallisiert in der monoklinen Raumgruppe P21/n mit a = 855,5 pm, b = 1263, 7 pm, c = 1245,3 pm, β = 104,94°, Z = 4. Nach kurzzeitigem Aufschmelzen kristallisiert die kubische Modifikation (P4S9 II), während längeres Schmelzen zur Kristallisation des P4S9 I führt.
