    The MRI signs of spinal arachnoid diverticula (1997)
    Springer
    Neuroradiology 39 (1997), S. 446-449

    ISSN: 1432-1920

    Notes: Abstract Our goal was to find MRI signs of use for identifying a spinal arachnoid diverticulum. Three cases of spinal arachnoid diverticula, one extradural and two intradural, were examined on a 1.5 T imager. There was obvious mass effect on the adjacent structures in one case and increased signal intensity in the diverticulum on proton density- and T2-weighted images in two cases. Signal changes due to turbulent movement of the spinal fluid inside the diverticula were seen in all cases on sagittal fast spin-echo (FSE) proton density- and T2-weighted images; it was difficult to tell whether these signal changes imply a communication or are simply FSE artefacts. On contrast-enhanced studies, all cases showed partial enhancement inside the diverticula. There thus are four signs of diverticula: mass effect, the increased signal, signal void sign and partial enhancement; the last of these, the most reliable, has never been reported before.

    Central gadolinium enhancement of an acute spontaneous spinal epidural haematoma (1996)
    Springer
    Neuroradiology 38 (1996), S. S114 
    Details
    ISSN: 1432-1920
    Keywords: Key words Spine ; haemorrhage ; Gadolinium ; Magnetic resonance imaging
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract Spontaneous spinal epidural haematoma (SSEH) is uncommon, but central gadolinium (Gd) enhancement of the haematoma is even rarer. To our knowledge, only one case has been reported, but no explanation was given concerning the mechanism of this enhancement. We present a case of SSEH with unusual central Gd enhancement which we believe is due to oozing from the injured posterior internal venous plexuses. Therefore, although rare, central Gd enhancement of an epidural mass should not rule out the possibility of a haematoma.

    Salicylic acid inhibits the biosynthesis of ethylene in detached rice leaves (1993)
    Springer
    Plant growth regulation 12 (1993), S. 79-82 
    Details
    ISSN: 1573-5087
    Keywords: ethylene biosynthesis ; salicylic acid ; Oryza sativa

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract The effects of salicylic acid (SA) on ethylene biosynthesis in detached rice leaves were investigated. SA at pH 3.5 effectively inhibited ethylene production within 2 h of its application. It inhibited the conversion of ACC to ethylene, but did not affect the levels of ACC and conjugated ACC. Thus, the inhibitory effect of SA resulted from the inhibition of both synthesis of ACC and the conversion of ACC to ethylene.

    Changes in putrescine accumulation induced by agents affecting cytosolic pH in detached rice leaves (1993)
    Springer
    Plant growth regulation 13 (1993), S. 133-136 
    Details
    ISSN: 1573-5087

    Notes: Abstract Effects of compounds that influenced cytosolic pH on the level of putrescine in detached rice leaves were examined. Permeant weak acids, isobutyric acid and propionic acid, increased the level of putrescine in detached rice leaves. Procaine and trisodium citrate, known to be permeant weak bases, on the other hand, decreased the level of putrescine. It seems possible that the level of putrescine in detached rice leaves is regulated by the cytosolic pH.
