    Early receptor potential from the pineal photoreceptor (1975)

    Notizen: Summary Rapid photoresponses were obtained from the pineal organ ofRana catesbeiana andRana esculenta comparable to the early receptor potential (ERP) of the retina of their lateral eyes. Light source was a xenon filled discharge tube with a maximum energy input of 365 J. The flash duration was 600 μsec measured at 1/3 peak amplitude. The response pattern of the ERP of the exposedEpiphysis cerebri (intracranial portion of the frog's pineal organ) resembled the ERP of the isolated retina and the R1 deflection of the ERP of the eye-cup. It was greatly diminished during consecutive flashes and was absent during light adaptation. It was confined to theEpiphysis cerebri and was similar in time course and shape to, though smaller as, the ERP of the isolated retina. The photoresistant component of the ERP in the eye-cup was lacking in theEpiphysis cerebri and in the isolated retina. The action spectrum of the ERP of theEpiphysis cerebri closely resembled the photopigment absorption of rhodopsin indicating that the structural cones of the pineal organ contain a photopigment different from the retinal cones of the frog's lateral eye.

    Some comments on the urethral syndrome (1976)
    Springer
    International urology and nephrology 8 (1976), S. 47-54 
    Details

    Thema: Medizin
    Notizen: Abstract In three-quarters of the patients with urethral syndrome, chronic urethritis was found endoscopically. Of the remainder some percentage could be said to have a psychosomatic disorder. Therefore, the patients with unexplained urethral syndrome were unexpectedly few. Although urethral syndrome attacks adult females of all ages, the incidence was highest in the middle age range. Against this, chronic bacterial cystitis was spread evenly over the entire age range. The urethra was rather narrow in women with urethritis, but of normal size in those without urethritis, even if they had urethral syndrome. A satisfactory result was obtained through the topical administration of steroid solution, even where general treatments, including the use of antibiotics, have failed.

    Histological investigation on the so-called urethral syndrome (1979)
    Springer
    International urology and nephrology 11 (1979), S. 95-102 
    Details
    ISSN: 1573-2584

    Thema: Medizin
    Notizen: Abstract The urethral syndrome is generally not associated clinically with urethral changes, however, histology often reveals inflammatory or degenerative alterations. The conventionally diagnosed urethral syndrome can certainly be considered to be a synonym of chronic urethritis in adult females. The remarkable histological lesions were rupture of elastic fibers in the submucosa and the vascular wall, and a decrease of acid mucopolysaccharides in each layer of the urethra, accompanied by lymphocytic infiltration.

    Casting of organic glass by radiation-induced polymerization of glass-forming monomers at low temperatures. VI. Casting polymerization of methyl methacrylate prepolymer by irradiation (1978)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 22 (1978), S. 43-52 
    Details
    ISSN: 0021-8995
    Schlagwort(e): Chemistry ; Polymer and Materials Science

    Thema: Chemie und Pharmazie , Maschinenbau , Physik
    Notizen: Casting of methyl methacrylate prepolymer by irradiation at relatively low temperatures was studied. It was difficult to completely glassify the methyl methacrylate monomer and prepolymer, and so the casting was carried out at temperatures above its melting point (-48°C). The optical strain formed in this stream remained of the stress type, and optical strain formation was reduced with increasing prepolymer concentration and decreasing temperature.
