Jing Song, Wenbo Wang, Catherine E Carr, Zhendong Dai, Yezhong Tang
Immunohistochemical techniques were used to describe the distribution of the calcium binding proteins calretinin, calbindin and parvalbumin as well as synaptic vesicle protein 2 in the vestibular nuclei of the Tokay gecko (Gekko gecko). In addition, tract tracing was used to investigate connections between the vestibular nerves and brainstem nuclei. Seven vestibular nuclei were recognized: the nuclei cerebellaris lateralis (Cerl), vestibularis dorsolateralis (Vedl), ventrolateralis (Vevl), ventromedialis (Vevm), tangentialis (Vetg), ovalis (VeO) and descendens (Veds)...

In the first part of this review the definition of vertigo/dizziness was discussed. The major difference between the two signs is the existence of the direction, which is specific for vertigo. Dizziness is a frequent complaint in the clinical practice. Its frequency is increasing with advance of age, to intimate the play of declining cognitive process in the pathogenesis of its. The popular health significance of vertigo is in the rowing number of the patients. The onset of the most cases with acute vertigo appears between secundums and minutes so the patients will be provided in circumstances of emergency department...

One year after neuritis vestibularis, 29% from a sample of 75 patients still complained of vertigo. The objective of this investigation was to study why patients suffer from persisting vertigo. The alternative hypotheses were that the vertigo experienced could be explained either by a persisting vestibular dysfunction or by psychopathological changes. To elucidate this question, patients were examined with dynamic posturography, the symptom check list (SCL 90 R), the state-trait anxiety inventory (STAI), the agoraphobic cognitions questionnaire (ALQ) and the body sensations questionnaire (BSQ)...

OBJECTIVE: Vertigo is one of the most frequent complaints in general medical practice and is often linked to psychiatric disorders. A longitudinal study of 67 patients with an acute vestibular disorder was undertaken to clarify if, after experiencing acute vestibular vertigo, certain patients have a higher likelihood of developing chronic, debilitating dizziness despite no evidence of a damaged peripheral vestibular system. METHOD: The severity of dizziness was determined in 67 patients with vestibular neuronitis, 6 months after their release from hospital, using the Vertigo Symptom Scale from Yardley et al...

BACKGROUND: Lyme disease has been described as one possible cause of sudden sensorineural hearing loss and vestibular neuronitis. The necessity of serological diagnosis and its therapeutic consequences have been discussed controversially. PATIENTS AND METHODS: 344 patients with acute sensorineural hearing loss and 66 patients with vestibular neuronitis were examined in retrospect. By means of ELISA (Enzygnost Borreliosis, Dade Behring Marburg) the specific prevalences of IgG- and IgM-antibodies against borrelia in serum were evaluated...

In mammals, sparse data illustrated the neuronal expression of S100 protein in central and peripheral nervous system. Similar studies have not been performed in other vertebrate species, in particular in birds. We provide here a detailed description of the distribution of the calcium-binding protein S100 in neuronal and glial elements in the central nervous system of an avian species, the Japanese quail (Coturnix japonica) largely used for neuroanatomical and functional studies. The distribution of S100-like immunoreactivity was analyzed by three different antisera: a polyclonal, against S100 protein, and two monoclonals, against the beta-subunit (S100beta) and the alpha-subunit (S100alpha) of this protein...

The vestibular apparatus provides information about the position and movements of the head. Craniocervical muscles position the head with respect to the upper part of the neck. Motoneurons innervating these muscles are located in the supraspinal nucleus and ventral horn of the rostral cervical cord. Premotor neurons of craniocervical muscles have been found in the medial two-thirds of the medullary reticular formation: the ventromedial part of the parvocellular reticular formation and the gigantocellular reticular formation...

It is well known that diseases of the vestibular system can be compensated by increased spontaneous activity of other systems engaged in maintaining equilibrium, i.e. proprioceptive and visual systems. A complex approach using multisensory stimulation is the optimal way to achieve vestibular compensation. The aim of our study was to determine the effect of vestibular rehabilitation therapy as measured by posturography in a group of 72 patients suffering from vestibular disorders: Ménière's disease (n = 31), neuritis vestibularis (n = 21) and vertebrobasilar insufficiency (n = 20)...

Interposito-vestibular connections were analysed, using the anterograde and retrograde tracer biotinylated dextran amine. The interposito-vestibular projections mainly arise from medial portions of the cerebellar nuclei interpositi anterior (NIA) and posterior (NIP), and reach each of the main vestibular nuclei, ipsilaterally. The highest density of projections is found throughout nucleus vestibularis lateralis. Fibres also reach the peripheral part of nucleus superior, the caudal part of nucleus inferior, and the lateral part of nucleus medialis...

The causality of vascular and parenchymal damage to the central nervous system (CNS) was examined in rats with thiamine deficiency. Male Sprague-Dawley rats were divided into two groups; one was given a thiamine-deficient diet (TDD) and injected intraperitoneally with 10 micrograms/100 g bodyweight pyrithiamine (PT) in order to analyze morphometrically the topographical and sequential relationship between vascular and parenchymal changes and vasodilatation, and the other was given a TDD and 50 micrograms/100 g bodyweight PT in order to determine hemorrhagic sites using serial sections...

The neuropeptide somatostatin is widely distributed in the central nervous system of rat and human. Somatostatin-containing neurons are particularly abundant in the hypothalamus, the cerebral cortex and the limbic system. Somatostatin is also present in a number of discrete structures in the brainstem and spinal cord. The localization of somatostatin receptors provides valuable information regarding the possible roles of the peptide in the brain. In the present study, we have investigated the precise distribution of somatostatin binding sites in the human lower brainstem by quantitative autoradiography, using [125I- Tyr0,DTrp8]S14 as a radioligand...

The distribution of serotonin (5-HT)-containing perikarya, fibers and terminals in the brain of the pigeon (Columba livia) was investigated, using immunohistochemical and immunofluorescence methods combined with retrograde axonal transport. Twenty-one different groups of 5-HT immunoreactive (IR) cells were identified, 2 of which were localized at the hypothalamic level (periventricular organ, infundibular recess) and 19 at the tegmental-mesencephalic and rhombencephalic levels. Ten of the cell groups were situated within the region of the midline from the isthmic to the posterior rhombencephalic level and constituted the raphe system (nucleus annularis, decussatio brachium conjunctivum, area ventralis, external border of the nucleus interpeduncularis, zona peri-nervus oculomotorius, zona perifasciculus longitudinalis medialis, zona inter-flm, nucleus linearis caudalis, nucleus raphe superior pars ventralis, nucleus raphe inferior)...

In order to elucidate the relationship between several structures of CNS and the vestibulo-sympathetic response (VSR) in rat, the technique of spike triggering average (STA) was used. The spike of the neuron which responded to the pendular rotation (pendular positive unit, PPU) was used to trigger the onset of averaged activities of the splanchnic nerve (SN). Making use of the spike of PPU of nucleus vestibularis medialis (NVM) as an indicator, the SN-STA had a latency of 33.28 +/- 3.1 ms. SN-STA triggered by PPU of reticular formation (RF) of caudal brain stem, a positive response with a latency of 11...

Recent evidence suggests that brain cells can synthesize steroids de novo. The steroidogenic enzyme 3 beta-hydroxysteroid dehydrogenase (3 beta-HSD) gene family of enzymes is involved in the biosynthesis of all classes of active steroids. In the present study, we have used in situ hybridization performed with a 35S-labeled cDNA-encoding rat type I 3 beta-HSD to localize the expression of member(s) of this gene family in the adult rat brain. A specific hybridization signal could only be detected in a restricted area of the medulla ventrally and laterally bordering the fourth ventricle...
