Pathomechanism of Brain Oedema in Experimental Intracerebral Mass Haemorrhage

1988

The prognosis of intracerebral haemorrhage is extremely poor when arterial hypertension is present. We investigated elastance of the brain tissue and brain hydraulic conductivity in normotensive (MAP ~ 110 mmHg) and hypertensive (MAP ~ 170 mmHg/angiotensin infusion) cats following a stereotactically produced intracerebral haemorrhage. For 12 hours after the onset of haemorrhage we registered the course of ICP, subsequently the water content of cortex, white matter and basal ganglia as well as the interstitial concentration of serum proteins in the corresponding regions were determined (Evans-Blue, immunofluorescence). Hypertension was associated with a slight increase in ICP and tissue wate…

Role of mitochondria in parvovirus pathology.

2014

Proper functioning of the mitochondria is crucial for the survival of the cell. Viruses are able to interfere with mitochondrial functions as they infect the host cell. Parvoviruses are known to induce apoptosis in infected cells, but the role of the mitochondria in parvovirus induced cytopathy is only partially known. Here we demonstrate with confocal and electron microscopy that canine parvovirus (CPV) associated with the mitochondrial outer membrane from the onset of infection. During viral entry a transient depolarization of the mitochondrial transmembrane potential and increase in ROS level was detected. Subsequently, mitochondrial homeostasis was normalized shortly, as detected by rep…

Die Verteilung von Noradrenalin und Adrenalin im Herzen der Katze, des Kaninchens und der Ratte

1958

The concentration of noradrenaline in different parts of the heart was estimated in cats, rabbits, and rats. In each heart, the concentration of noradrenaline was much higher in the right atrium than in the left atrium and higher in the right ventricle than in the left one.

The action of iontophoretically applied acetylcholine and dopamine on single claustrum neurones in the cat.

1981

Abstract The effects of iontophoretically applied acetyl-choline (ACh) and dopamine (DA) on spontaneously active claustral neurones, in chloralose-anaesthetised cats, have been investigated. Acetylcholine had both facilitatory and inhibitory effects in almost the same proportions. The action of DA was prevalently inhibitory. Two types of inhibitory response to ACh and DA are described: short-lasting inhibition and long-lasting inhibition. The excitatory response always outlasted the period of drug application.

Die Konzentration von Noradrenalin und Adrenalin in den einzelnen Abschnitten des Herzens

1959

1. A method for the assay of noradrenaline and adrenaline in small pieces of heart tissue is described. The amines were extracted with acid ethanol and separated by paper chromatography. The regions containing the amines were eluted and the amount of amines in the eluates was determined by bioassay. Noradrenaline was assayed on the blood pressure of the pithed rat. Adrenaline was assayed on the isolated atropinized rat's uterus stimulated with oxytocin. 2. The identity of the substances tested by bioassay with noradrenaline and adrenaline was confirmed by a number of chemical and pharmacological tests. 3. The concentration of catechol amines in different parts of the heart was studied in ca…

The control of amygdaloid and temporal paroxysmal activity by the caudate nucleus

1971

In gatti curarizzati ed in gatti portatori di elettrodi a dimora e liberi di muoversi, la stimolazione ripetitiva ad alta frequenza del nucleo caudato inibisce la comparsa sia dei fenomeni bioelettrici parossistici focalizzati nell'amigdala e nella corteccia temporale sia dei fenomeni comportamentali omologabili all'epilessia psicomotoria.
