    Atopic dermatitis and congenital deafness (1978)

    Notizen: In a family with perceptive, non-progressive hearing loss several of the members suffered from atopic dermatitis. The proband had a severe atopic dermatitis and an extremely high IgE value. Some of the family members suffered from atopic dermatitis, others from deafness, and some from both diseases. The co-existence of these two disorders has been previously described in two families. Atopic dermatitis and perceptive, non-progressive congenital deafness might be genetically associated.

    Notizen: Zusammenfassung Dressurversuche zur Untersuchung der optischen Leistungsfähigkeit von Frettchen und Iltisfrettchen im Bereich der Wahrnehmung unterschiedlicher Figurengrößen erbrachten folgende Resultate: 1. Regelmäßige geometrische Figuren (Kreis, Quadrat) im Größenbereich 30–60 mm Ø werden aus 1 m Entfernung bis zu einer Flächendifferenz von 16,5% noch eben unterschieden, was einem Sehwinkel von 16′12″ entspricht. 2. Diese Leistung bleibt konstant im Helligkeitsbereich 260-0,1 Lux, dann sinkt sie rasch ab. 3. Im kritischen Wahlbereich wird typisches Konfliktverhalten beobachtet, unter anderem aggressive Verhaltensweisen und regressives Verhalten. 4. Bei einem Tier konnte vor der Umstellung auf rein optische Orientierung kinästhetische Orientierung (Umfahren des Merkmals mit der Schnauzenspitze) nachgewiesen werden, die „Speichelfiguren“ auf dem Merkmalsglas hinterließ.

    Contractile responses to direct stimulation of frog slow muscle fibres before and after denervation (1979)
    Springer
    Pflügers Archiv 382 (1979), S. 43-50 
    Details
    ISSN: 1432-2013
    Schlagwort(e): Slow fibres ; Contractile responses ; Effect of denervation

    Thema: Medizin
    Notizen: Abstract 1. The contractile responses of single slow muscle fibres were investigated under isometric conditions. The fibres were isolated from normal and denervated iliofibularis muscles ofRana temporaria. Direct stimulation was achieved by external application of electrical pulses or depolarizing solutions (40 mM K and acetylcholine 10\t-6 g/ml). 2. Upon electrical stimulation normal slow fibres developed contractions whose amplitude increased steadily with the strength of the pulses. These contractions did not exceed 0.22 kg/cm2, and their rates of rise and fall were approximately 1/6 of those observed in twitch fibres. During pulses of several 100 ms duration the tension continued to rise slowly until the end of the pulses. Application of 40 mM K or acetylcholine resulted in contractures which reached maximum values of 1.71 and 1.87 kg/cm2, respectively, after less than 1 min; little relaxation occurred during the following minutes. 3. The responses of slow fibres denervated for 9−76 days differed in several respects from those of normal slow fibres. a) The contractions elicited by electrical stimulation became faster but their amplitude decreased; the relationship between tension and pulse strength remained, however, essentially unchanged. b) Small and short contractions could be observed during and at the end of stimulating current pulses. Their amplitude was independent of the amplitude and duration of the stimuli; they were blocked by tetrodotoxin and must be attributed to action potentials. c) The ability to develop and maintain tension was reduced. Maximum values of K- and acetylcholine contractures were generally only 50% of those observed in normal slow fibres. Maintenance of tension was markedly reduced in some fibres, less so in others. 4. It is concluded that incorporation of Na channels into its membrane does not transform the slow fibre into a type of fibre which resembles a twitch fibre.

    Effect of nerve length and temperature on the induction of action potentials in denervated slow muscle fibres of the frog (1977)
    Springer
    Pflügers Archiv 372 (1977), S. 17-22 
    Details
    ISSN: 1432-2013
    Schlagwort(e): Slow muscle fibres ; Action potential ; Nerve stump ; Temperature
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Summary A. Pyriformis and extensor longus digiti IV muscles of Rana temporaria were denervated by cutting the sciatic or peroneal nerve at various distances from the muscles. Slow fibres were identified by their membrane time constants, and examined for their ability to produce action potentials in response to intracellularly applied current pulses. B. The slow muscle fibres acquired the ability to generate action potentials several days after denervation. The duration of this latent period depended on the length of the peripheral nerve stump, and on the temperature at which the frogs were kept after the operation. C. At 18°C the latent period increased by 0.36 days per mm of sciatic nerve stump. At 11.5° C the corresponding value was 0.7 days/mm. The effect of length of the peroneal nerve was smaller than that of the sciatic nerve. D. It is suggested that the peripheral nerve stump serves as a reservoir of ‘trophic’ material which is transported towards the slow fibres at a rate of 2.8 mm/day (at 18° C) and seems to block the formation of Na channels. TheQ 10 value of this transport system would be 2.7.

    Changes in envelope permeability during chloroplast development (1976)
    Springer
    Planta 129 (1976), S. 69-73 
    Details
    ISSN: 1432-2048
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie
    Notizen: Summary The permeability of the plastid envelope during the development of Avena sativa plastids was investigated by light scattering and uptake of various labelled compounds (malate, succinate, glutamate, α-ketoglutarate, citrate, glycine, sucrose). The results presented show that a primary event during greening is a change in permeability, thereby allowing an increased transport of metabolites across the membranes of very early etio-chloroplast stages. The results are discussed in view of an adaption of the plastid envelope permeability to the changing requirements of externally synthesized precursors and intermediates during development.

    Notizen: Summary 1. In the rabbit overdosage with cortexone and salt leads to a deterioration of general condition, sodium retention and potassium loss, muscular paralysis and effusions in the pleural, pericardial and peritoneal cavities. In general rabbits are more sensitive to overdosage with cortexone and salt than rats. 2. Contrary to the rat in none of the animals a definite increase of blood pressure has been observed. 3. Kidney extracts prepared from animals pretreated with cortexone and salt showed a loss of pressor activity if tested semiquantitatively in the nephrectomised rat. It can be concluded that the disappearance of pressor active material from the kidney (renin) is not responsible per se for the development of hypertension. 4. There are various factors which may be responsible for the lack of blood pressure response in the rabbit.
