    Notes: Bush beans, kale and soybeans were used as models for studying the effects of processing by canning and freezing upon 51Cr and 65Zn content. Plants were grown hydroponically, intrinsically labeled with 51Cr and 65Zn, and processed either by canning or freezing. Freezing resulted in 65Zn losses of 10.7% for kale, 8.6% for bush beans, and 6.7% for soybeans. A loss of 3.8% of 51Cr resulted during freezing of bush beans. Canning resulted in 65Zn losses of 23% for kale, 19.7% for bush beans, and 28.8% for soybeans. Canned bush beans and kale contained 40.7% and 62.7% respectively, less 51Cr than unprocessed samples. Freezing resulted in a greater mineral retention than canning. Less opportunity for leaching is available in freezing and reduction in radionuclide content of the vegetables by canning was accounted for by transfer to the drained liquid.

    Description / Table of Contents: Zusammenfassung Es wird über einen zwölfjährigen Jungen berichtet, der an einer akuten basalen Subarachnoidalblutung nach einer tätlichen Auseinandersetzung — von Augenzeugen nur als Rangelei bezeichnet — mit einem Klassenkameraden verstarb. Als Blutungsquelle wird eine Gefäßruptur im System der Vena cerebri magna Galeni und der Vv. cerebri parvae (internae) auf dem Boden einer möglichen mikrodysontogenetischen Vorschädigung der Gefäße diskutiert.
    Notes: Summary Report of the case of a 12-year-old boy who had died due to massive basal subarachnoid hemorrhage after moderate fight with a class mate. Findings at autopsy and by microscopic examination indicated that a lesion in the system of the great vein of Galen and the internal cerebral veins might have been the source of the bleeding. The nature of an underlying pre-existing vascular change favoring a rupture is discussed on the basis of the clinical history and the pathoanatomic findings.

    Notes: Summary The generalized form of von Winiwarter-Buerger's disease (WBD) occasionally involves the brain. However, pure cerebral forms of the disease were also described by Spatz and Lindenberg (“Spatz-Lindenberg's disease”, SLD). Both, the type I, which involves the large basal arteries, and the type II, which results in a sickle-shaped granular atrophy of the cerebral cortex, are often accompanied by (“vascular”) dementia, which Lindenberg and Spatz mainly attributed to the bilateral involvement of the second frontal gyrus by granular atrophy. Recently, synaptic deprivation of the cortical gray matter has been shown to occur in the dementia of Alzheimer type (DAT) and other neurodegenerative disorders. In DAT, the synaptic loss highly correlated with the degree of the mental impairment. We wanted to examine whether similar changes also occurred in dementia of vascular origin, for which SLD, although infrequent, is a typical example. In fact, we found that in three cases of typical SLD type II the synaptophysin immunoreactivity of the cortical neuropil in areas without overt infarcts or scar formation was as much reduced as in Alzheimer's disease. Although it must be taken into account that in the present cases the synapse loss might, at least in part, be due to secondary (Wallerian) degeneration as a result of the neuronal loss in the “watershed” regions of the arterial blood supply, it cannot be excluded that a decline of cortical synaptic contacts in areas without necroses or scars may occur as a primary event, contributing to the pathogenesis of the dementia. Final conclusions can only be expected from investigations into further cases of cerebro-vascular disorders with and without dementia.

    Description / Table of Contents: Summary The deflection of a plane turbulent jet in a crossflow is described by a model which takes the effects of entrainment as well as those of crossflow pressure into account. Using this model the centerline and the spread of the jet and the mean velocity averaged over its cross-section can be calculated. Asymptotic analytic solutions are given for the case where the velocity of the unperturbed crossflow is much smaller than that of the unperturbed jet. A comparison of the present calculations with experimental results of other authors shows good agreement.
    Notes: Übersicht Zur Beschreibung der Umlenkung eines ebenen turbulenten Freistrahles durch eine Querströmuug wird ein Modell entwickelt, bei dem sowohl die Einsaugwirkung des Strahles als auch die Druckwirkung der Querströmung auf den Strahl berücksichtigt werden. Hiermit können die Strahlmittellinie, die Strahlbreite und die über einen Strahlquerschnitt gemittelte Geschwindigkeit berechnet werden. Es werden analytische Näherungslösungen für die Fälle angegeben, in denen die Geschwindigkeit der ungestörten Querströmung wesentlich kleiner als diejenige des ungestörten Strahles ist. Ein Vergleich der berechneten Größen mit experimentellen Ergebnissen anderer Autoren zeigt gute Übereinstimmung.

    Notes: Summary Report of a 33-year-old man with a yearlong historory of low-back pain radiating into the left leg. Neurologic examination upon admission tto the hospital revealed a spinal compression syndrome at the lovel L5. Laminectomy at L4/5 revealed an encapsulated intradural tumor measuring 4×2.5×2.5 cm. The tumor was attached to the dorsal root L4 and extended downward to the conus region. Light and electron microscopy revealed features mostly consistent with a mixed chemodectoma and ganglioneuroma.

    Notes: Abstract Thin sections in the thickness range down to 3–5 μm were produced from bariumtitanate ferroelectric ceramics. The small signal dielectric constant, as well as hysteresis loops were measured. Significant deviations from the bulk properties were observed, when the thickness of the sample was decreased to the average diameter of the grains. The measured results are discussed proposing a model with internal stresses and a distorted surface layer.

    Description / Table of Contents: Zusammenfassung Die Inzidenz von ZNS-Shuntinfektionen und damit verbundenen Risikofaktoren wurde durch Auswertung von Krankenakten untersucht. Zwischen 1986 und 1989 wurden 350 Shunt-Operationen durchgeführt, wobei 273 Shunts ventrikuloperitoneal und 75 ventrikuloatrial plaziert wurden. Bei 25 Patienten kam es während eines mittleren Beobachtungszeitraumes von 20 Monaten zu 28 Shuntinfektionen (8 %). Für 204 Patienten konnte die Nachbeobachtungszeit bis September 1992 ausgedehnt werden, weitere Infektionsfälle wurden in dieser Gruppe nicht beobachtet. In 24 Fällen (85,7 %) konnte ein ursächlicher Erreger isoliert werden. Bei den Erregern handelte es sich um grampositive Kokken in 22 Fällen (78,6 %) und um gramnegative Stäbchen in zwei Fällen. Hauptsymptome und -Befunde waren Fieber, Shuntdysfunktion und meningeale Reizerscheinungen sowie Bauchschmerzen (letztere ausschließlich bei VP-Shunts). Bei 24 Infektionsfällen wurde der Shunt sofort entfernt und eine antibiotische Therapie begonnen, in den übrigen Fällen erfolgte ausschließlich eine antibiotische Therapie. Ursache des Hydrozephalus, Shuntlage, perioperative Antibiotikagabe, Alter und Geschlecht eines Patienten waren nicht mit einem erhöhten Infektionsrisiko assiziiert, jedoch ergab sich ein Trend, der ein erhöhtes Infektionsrisiko mit der Operationsdauer zeigte. Die Infektionsrate lag bei 13,6% für eine Operationsdauer von 〉90 Minuten, während sie bei 5,2 % für Eingriffe mit einer Dauer von 〈30 Minuten lag.
    Notes: Summary The incidence of shunt infections and possible risk factors was investigated by chart analysis. From 1986 to 1989 350 shunt procedures were performed including 273 ventriculoperitoneal shunts and 75 ventriculoatrial shunts. Twenty-eight infectious episodes (8%) occurred in 25 patients during a median follow-up time of 20 months. For 204 patients the follow-up time could be prolonged until September 1992. In these patients no infectious episodes occurred in the extended observation period. In 24 cases (85.7%) a causative organism could be isolated. The infecting organisms were gram-positive cocci in 22 cases (78.6%) and gram-negative bacilli in two cases. The main signs and symptoms were fever, shunt malfunction and meningeal irritation, and with VP-shunts only, abdominal pain. Twenty-four infectious episodes were treated with antibiotics and immediate removal of the shunt. The remaining were managed with antibiotics only. The risk for shunt infection did not correlate with age or sex of patients, nor with the etiology of hydrocephalus, type of shunt implanted or perioperative antibiotic prophylaxis. However, a trend showing a higher risk for shunt infections with prolonged operation time was noticed. The infection rate was 13.6% for an operation lasting more than 90 minutes versus 5.2% for procedures of less than 30 minutes' duration.

    Notes: Summary The purpose of the present study was to characterize the effects of mianserin at α2-adrenoceptors. Firstly, the action of mianserin on postganglionic sympathetic fibres has been studied using the tachycardia induced by stimulation of the cardiac nerve in dogs. Mianserin increased this tachycardia, but could not prevent the inhibitory effect of clonidine in this model. However, an antagonistic effect of mianserin against clonidine was observed when animals were pretreated with desipramine. Secondly, mianserin antagonized the inhibitory effect of clonidine on the electrically stimulated guinea-pig ileum. In high concentrations, mianserin reduced both electrically and acetylcholine induced contractions. Thirdly, mianserin antagonised the sleep induced by clonidine in chickens. These results are consistent with α2-adrenoceptor blocking properties of mianserin in peripheral noradrenergic fibres in dogs, in cholinergic fibres in guinea-pig ileum and in the central nervous system in chickens.
