Headache with paroxysmal vertigo were induced by cough in a case of the Arnold-Chiari type I malformation. The authors suggest that exertional headache and posterior cranial fossa symptoms of unclear aetiology may indicate presence of the syndrome, and the availability of magnetic resonance imaging made possible the detection of the malformation.
Position, shape and cytoarchitecture of the supraoptic nucleus were observed in 30 guinea pigs of both sexes, in serial frontal sections of the hypothalamus stained selectively for neurosecretion content, with regard to the sex of the animals examined and hypothalamus sides. Three morphological units of the nucleus were distinguished (parts: oral, principal… (More)
After 7 or 30 days of exposure to general vibration (frequency: 40 Hz, amplitude: 1 mm) for 3 hours per day, the prosencephalon of guinea pigs exhibited a wide range of morphological changes, including congestion, haemorrhages, the presence of the heterochromic neurons and perivascular spaces as well as diffuse spongiosis. In contrast, after 14 days'… (More)
The authors describe two cases of Shy-Drager Syndrome in the aspect of diagnostic difficulties. The simple tests for evaluation of automatic system function, especially orthostatic test are stressed.
Some disorders of the brain stem and spinal cord microcirculation were observed in male adult guinea pigs exposed to vertical vibration of frequency 40 Hz and amplitude 1 mm for 3 hours daily during 7, 14, 30 days. These changes after 7 days of vibration were seen as congestion with single small haemorrhages and after 14 days as diffuse spongiosis of the… (More)
In the spinal ganglia of guinea pigs exposed to general vibration of 40 Hz frequency and 1 mm amplitude for 3 hrs daily, gradually increasing morphological lesions were found after 7, 14, 30 and 90 days of the experiment. The animals exposed to vibration for up to 30 days exhibited a decrease in the cell nuclei volume, increase in the occurrence of… (More)
Position, shape and cytoarchitecture of the paraventricular nucleus were observed in 30 guinea pigs of both sexes, in serial frontal sections of the hypothalamus stained selectively for neurosecretion content, considering the sex of the animals examined and hypothalamus sides. Three morphological units of the nucleus were distinguished (parts: oral,… (More)
