Primary malignant mesenchymal tumours were seen in 2.4 per cent of all autopsy cases with primary CNS-tumours. Primary leptomeningeal sarcomatosis is rare in this group of tumours. We discuss the rare disease on the basis of the case history of a 26-year-old patient.
Specimens from the area 10 of the frontal cortex collected out of 7 patients with severe mental retardation, aged 3 to 24 years and also 8 non-neuropsychiatric age-matched controls were processed according to the Golgi-Kopsch method. The total length of the apical side-dendrites and of the basal dendrites was measured on layer V pyramidal neurons. Compared… (More)
We investigated brain tissue from 7 deceased patients with Fahr's disease using X-ray-analysis for the determination of compositional differences between calcareous particles in different areas of brain or between the left and right sides in a brain and differences in composition of concrements in different brains. We found, in all areas of one brain no… (More)
In the present study an experimental rat model is presented enabling analysis of nerve regeneration in vivo through preformed tissue holes. The tissue space allows to bridge a gap about 10 mm. The neovascularization could follow the physiological course using the way through the epi- and perineurium in the chamber. The regeneration rate was investigated… (More)
Described in this paper is a new artificial chamber model to enable in vivo investigation of nerve fiber regeneration. Transection of the sciatic nerve of a rat was followed by analysis of axonal regeneration and revascularisation in the tissue chamber. Vascularisation of the endoneurium via the newly formed epineurium and perineurium was almost… (More)
After injuries innervationanomalies are observest. Are these anomalies mechanismen of adaption or an embryological malformation, is a still mansverst question. This paper tries some contributions to the answer. The use of modern muscleenzymhistochemistry in connection of histological findings of nerves in certain levels gives assertions on anomalies of… (More)
A brief account is given in this paper of latest knowledge on regeneration in peripheral nerve following axotomy. Structural changes are discussed together with metabolic peculiarities associated with such restoration. Separate reference is made to neurotrophic growth factors and their effects.
The deviation from anatomically described innervation can often occur. It is mainly described on muscles of the limbs. Constant attention should give to this fact during the process of diagnosis of peripheral nerve lesions. Electrophysiological methods (EMG, ENG with blockade of nerve, collision technique and simultaneous lead) can help to detect this… (More)
Since Plexus brachialis lesions mainly occur in young persons, their socio-medical significance is undisputed. While the diagnostic rules are largely standardised, the time and the kind of the surgical intervention is disputed. The enzymic-histochemical examination of the denervated muscles of nine patients confirm the trend towards an intervention as early… (More)
A syndrome with constant rest activity was observed in the EMG of a 28-years-old female patient. An H-reflex was detected for normal nerve conduction velocity. Hypomagnesemia was striking among the laboratory values. Bioptic investigation yielded centralisation of nuclei, variations in the diameter of muscle fibres and a predominance of type I fibres. The… (More)
