The claustrocortical connections in the rabbit were assessed for the first time by the method of axonal retrograde transport of two fluorescent tracers (Fast Blue and Diamidino Yellow). The material consisted of 23 adult New Zealand rabbits. Projection zones of spindle-like form, connected with the precentral, postcentral, temporal and occipital cortices(More)
The claustrum is a subcortical structure lying under the insular and piriform cortices, whose function is still not clear. Although data exist on connections of the claustrum and the limbic cortex, the topography of the limbic zone in the rabbit and rat claustrum has not been studied extensively. The study was performed on 17 adult Wistar rats and 12 New(More)
The retrograde axonal transport method was used to compare the topography and organization of the visual zone of the claustrum in rat, guinea pig, rabbit and cat. First, massive Fluoro-Gold injections were placed into the primary visual cortex and the secondary areas. Experiments showed differences in the location of the visual zone among the animals under(More)
The quantitative analysis of the claustrocortical connections labeled with the fluorescent retrograde tracer Fluoro-Gold (FG) was conducted on 90 rabbits subdivided into the following age groups (P2, P7, P14, P21, P30, P60, P90, P120, P180). The equal volumes of retrograde fluorescent tracer FluoroGold (FG) were injected into the selected regions of the(More)
The quantitative analysis of the claustrocortical connections in the rabbit, labeled with the fluorescent retrograde tracer Fluoro-Gold (FG), was conducted by means of unbiased stereology. The FG was injected into selected regions of the motor, somatosensory, auditory and visual cortices and then a comparison of the various claustrocortical projections was(More)
Intracerebral haematoma was produced in 25 adult rats by infusion of 100 microl of autologous blood into the striatum. The animals' brains were removed at 1, 3, 7, 14 and 21 days after production of the haematoma. The TUNEL method was used to detect DNA fragmentation and TUNEL-positive cells were qualified. TUNEL-positive cells were already found on the(More)
Intracerebral haemorrhage is a strong stimulus for both microglial and astroglial activations. There are some important pathophysiological features during haemorrhage that do not occur in ischaemic or traumatic brain injuries, and may influence the dynamics and intensity of glial activation. Studies on the evolution of glial reaction may have practical(More)
BACKGROUND Microglial cells play an important role in the pathophysiology of intracerebral haemorrhage. We have examined the possible influence of sevoflurane on the reactivity of microglial cells during intracranial haemorrhage. METHODS Forty adult male rats were divided into two groups. All animals were anaesthetized with fentanyl, dehydrobenzperidol(More)
BACKGROUND Sevoflurane is one of the newest volatile anaesthetic agents. The effect of sevoflurane on ICP in conditions of intracranial pathology is essential from the clinical point of view but still not sufficiently clear. The aim of the study was to examine the effects of 1 MAC, 2 MAC, 3 MAC sevoflurane on intracranial pressure (ICP), mean arterial blood(More)
