Postnatal expression of Doublecortin (Dcx) in the developing cerebellar cortex of mouse.

We have investigated the expression of Doublecortin (Dcx) protein in the developing cerebellum of mouse from postnatal 2nd day to postnatal 22nd day and in young adults by immunohistochemistry. Strong expression of Dcx was present in the inner zone of the external granule cell layer, and remained strong while postmitotic granule cell precursors were present in this transitory layer. Descending granule cell precursors exhibited Dcx immunostaining not only while migrating but for a short time also after their settlement.

Postnatal expression pattern of doublecortin (DCX) in some areas of the developing brain of mouse.

We have investigated the spatio-temporal expression pattern of doublecortin (DCX) protein from postnatal day (P) 2 to postnatal day (P) 22 in the brain of developing mouse. We compared the expression of DCX in the rostral migratory stream (RMS) and dentate gyrus of the hippocampus (DG). Weak expression of DCX was detected in the RMS at P5, it became gradually stronger during the second postnatal week and reached its strongest expression by P18-P22.

Calretinin-immunoreactive unipolar brush cells in the developing human cerebellum.

We have studied the temporal and spatial characteristics of the development of unipolar brush cells (UBCs) in the human cerebellar vermis. Consistently with previous studies in rodents and cat, we have found that unipolar brush cells appear at a relatively late phase of cerebellar development and their development continues up to and beyond the first postnatal year. A series of 23 normal human brains, including 5 adult and 18 fetal or infant brains (between the 24th gestational week and the 11th postnatal month) were used.

Delayed postnatal settlement of cerebellar Purkinje cells in vermal lobules VI and VII of the mouse.

The postnatal development of the ganglionic (Purkinje) layer was studied in the mouse cerebellum from P0 to young adulthood with special emphasis to vermal lobules VI-VII (oculomotor vermis) in the mouse. In order to visualize Purkinje cells (PCs), toluidine blue staining of resin-embedded semithin sections and calbindin immunohistochemistry were utilized. The number of PCs in the whole cerebellum was 199,080+/-2966 at postnatal day eight (P8), 222,000+/-2979 at P20 and nearly the same, 225,800+/-7549 in young adults; i.

Quantitative analysis of the postnatal development of Purkinje neurons in the cerebellum of the cat.

We have studied the postnatal quantitative changes of cortical Purkinje neurons in the cerebellum of the cat at the following postnatal groups of age: P0, P42, P72 and adults. An unbiased counting method, the optical fractionator was used for the estimation of Purkinje cell numbers. A significant increase of Purkinje cell number was found between P0 (1.

Distribution of mGluR1alpha and SMI 311 immunoreactive Lugaro cells in the kitten cerebellum.

The Lugaro cell is a feedback interneuron of the cerebellar cortex, recognizable by its characteristic morphology. Postnatal neuronal migration to the cortex has been described for several cerebellar interneurons. Since in our previous studies we observed Lugaro-like cells (LCs) in the white matter (WM) and internal granular layer (IGL) of the cerebellum of young cats, we assumed that a proportion of these cells migrate also postnatally to their destination.

Reorganization of monoaminergic systems in the earthworm, Eisenia fetida, following brain extirpation.

The present study describes the major aspects of how monoaminergic (serotonin, dopamine) systems change in the course of regeneration of the brain in the earthworm (Eisenia fetida), investigated by immunocytochemistry, HPLC assay, and ligand binding. Following brain extirpation, the total regeneration time is about 80 days at 10 degrees C. On the 3rd postoperative day serotonin, and on the 11th postoperative day tyrosine hydroxylase-immunoreactive neurons can be observed in the wound tissue.

Number of GABA immunonegative and GABA immunopositive neurons in human epileptic temporal cortex.

The number of neurons, both GABA immunopositive and immunonegative, was determined in temporal epileptic foci of 7 patients after temporal lobectomy, and compared to neuronal numbers in temporal cortex of two controls taken from tumor operated patients. The thickness of the cortex of the epileptic cortex diminished by about 10%, while the number of nerve cells decreased to 67% of that of the control value: it was 19.000/mm(3) vs.

Distribution and action of some putative neurotransmitters in the stomatogastric nervous system of the earthworm, Eisenia fetida (Oligochaeta, Annelida).

The chemical neuroanatomy of the stomatogastric nervous system of the earthworm, Eisenia fetida, has been investigated, using antibodies raised against serotonin, tyrosine hydroxylase, octopamine, GABA, FMRFamide, proctolin, Eisenia tetradecapeptide and neuropeptide Y. Neurons immunoreactive to these antibodies can be observed in the stomatogastric ganglia. The labelled cells comprise altogether 95.

Reorganization of peptidergic systems during brain regeneration in Eisenia fetida (Oligochaeta, Annelida).

After the extirpation of the brain reorganization of the peptidergic (FMRFamide, neuropeptide Y, proctolin) systems was studied in the newly forming cerebral ganglion of the annelid Eisenia fetida. During regeneration, all immunoreactive fibres appear on the 1st-2nd postoperative day. At the beginning of regeneration, immunoreactive neurons and fibres form a mixed structure in the wound tissue.

Distribution of Eisenia tetradecapeptide immunoreactive neurons in the nervous system of earthworms.

A detailed mapping of Eisenia-tetradecapeptide-immunoreactive neurons in the central and peripheral nervous system combined with quantitative morphological measurements was performed in Eisenia fetida and Lumbricus terrestris. In Eisenia, most labelled neurons were observed in the ganglia of the ventral cord (20.38% of the total cell number of the ganglion) and 15.

Postnatal development of unipolar brush cells in the cerebellar cortex of cat.

The postnatal developmental distribution pattern of metabotropic glutamate receptor (mGluR1a) immunoreactive unipolar brush cells (UBCs) was studied in the cerebellar cortex of kittens. On the day of birth (P0) UBCs are already present in the white matter in lobule X of the vermis, but only a few of these cell seemed to migrate to the deeper region of the internal granular layer. By the end of the first week (P8) UBCs were seen to invade the white matter + internal granular layer of lobules IX, VIII, I, and II of the vermis, and they spread further in the transitory area medio-laterally from the vermis toward the cerebellar hemispheres.

Innervation of a single vibrissa in the whisker-pad of rats.

Innervation of the gamma straddler vibrissa and distribution of individual gamma vibrissal sensory nerve fibers within infraorbital nerve branches were investigated in adult rats. In the close vicinity (2 mm) of the whisker-pad, one-fifth of the nerve fibers innervating the gamma vibrissa were still located in nerves to neighboring (beta, delta, C1 and D1) whiskers, while one-tenth of the innervating fibers were placed in nerves of more distant sinus hairs. This convergence of gamma vibrissal sensory nerve fibers to single vibrissa from neighboring nerves is suggested to be a consequence of overlapping vibrissal representation in the Gasserian ganglion.

Immunocytochemical mapping of NPY and VIP neuronal elements in the cat subcortical visual nuclei, with special reference to the pretectum and accessory optic system.

The aim of this study was to describe the distribution patterns of neuropeptide Y (NPY) and vasoactive intestinal polypeptide (VIP)-immunoreactive (ir) neuronal elements in subcortical visual centers of the cat. Numerous NPY-ir neurons were present in the feline nucleus of the optic tract and in the anterior pretectal nucleus. Only a few NPY-ir neurons were found in the posterior, medial and olivary pretectal nuclei and in the accessory optic nuclei.

Metabotrop glutamate receptor type 1a expressing unipolar brush cells in the cerebellar cortex of different species: a comparative quantitative study.

Morphology, distribution and number of unipolar brush cells (UBCs) was studied in the cerebellar vermal lobules I-X of the chicken, rat, guinea pig, cat, and monkey using monoclonal mGluR1a antibody as a marker to visualise these recently described nerve cells (Mugnaini and Floris [1994] J. Comp. Neurol.

Contralateral cortical projection to the mediodorsal thalamic nucleus: origin and synaptic organization in the rat.

The origin of the corticothalamic projections to the contralateral mediodorsal nucleus, the collateralization of cortical fibers and their synaptic organization in the ipsi- and contralateral mediodorsal nuclei were investigated in adult rats with double retrograde fluorescent and anterograde tracing. After tracer injections in the mediodorsal nuclei on either side, neurons were retrogradely labeled in all the areas of the contralateral prefrontal cortex in which ipsilateral labeling was also observed. Contralateral corticothalamic cells accounted for 15% of the labeled neurons in the orbital and agranular insular areas, while their proportion was lower (3%) in the anterior cingulate cortex.

Octopamine-containing neurons in the alimentary tract of the earthworm (Eisenia fetida).

Octopamine-containing nerve cells have been demonstrated in the enteric plexus of the earthworm (Eisenia fetida), applying immunocytochemistry and HPLC assay. A few octopamine-immunoreactive neurons occurred in the fore- and hindgut, whereas their number in the midgut was considerably greater. Octopamine levels detected by HPLC correlated with the distribution of octopamine-containing nerve cells.

Distribution of metabotropic glutamate receptor type 1a in Purkinje cell dendritic spines is independent of the presence of presynaptic parallel fibers.

The metabotropic glutamate receptor type 1a (mGluR1a) is expressed at a high level in the molecular layer of the cerebellar cortex, where it is localized mostly in dendritic spines of Purkinje cells, innervated by parallel fibers. Treatment with methylazoxymethanol (MAM) of mouse pups at postnatal days (PND) 0 + 1 or 5 + 6 results in the partial loss of granule cells, the extent of which depends on the age of the animal at the time of injection. As a consequence of hypogranularity, the number of parallel fibers is decreased to such an amount that many of the postsynaptic Purkinje cell dendritic spines are devoid of axonal input, and only a limited number of spines participate in the formation of parallel fiber synapses, or, infrequently, in heterologous or heterotopic synapses with other presynaptic partners.

Light and electron microscopic demonstration of mGluR5 metabotropic glutamate receptor immunoreactive neuronal elements in the rat cerebellar cortex.

The cellular and subcellular localization of the mGluR5 metabotropic glutamate receptor subtype was studied in the rat cerebellar cortex, by using the preembedding immunoperoxidase and immunogold techniques. Light microscopic observations revealed an abundant, intense labeling of neurons in the granular layer as well as in the molecular layer. Lugaro and Golgi cells exhibited an intense mGluR5 immunoreactivity, while only a fraction of the neurons in the molecular layer were found to be mGluR5 immunopositive.

Surgical treatment of pancreatic head and periampullary tumors.

The aim of this study was the comparison of the postoperative results of standard Whipple pancreatoduodenectomy (WP), pylorus preserving pancreatoduodenectomy (PPPD) and palliative bypass operation performed for treatment of pancreatic head and periampullary tumors. In the period from Jan. 1992 to 1996 106 patients had tumors located in the head of pancreas and 21 patients had periampullary tumors.

The role of different tumor markers in the early diagnosis and prognosis of pancreatic carcinoma and chronic pancreatitis.

The examination of tumor markers in the diagnosis and in the evaluation of progression of tumors has got an increasing significance. The serum level changements of three tumor markers (CEA, CA 19-9, CA 125) were examined before and after the operation in 94 patients operated for pancreatic carcinoma (PC) and chronic pancreatitis (CP) between March 1994 and December 1996 at the 2nd Dept. of Surgery of Debrecen Medical University.

Morphogenetic plasticity of neuronal elements in cerebellar glomeruli during deafferentation-induced synaptic reorganization.

Reorganization of the cerebellar glomerulus, the main synaptic complex within the granule cell layer, was investigated using quantitative morphological techniques. All afferents to the cerebellar cortex, including mossy-fibers, were surgically destroyed by undercutting the cerebellar vermis. Fifteen days after the operation, which resulted in the removal of the main excitatory afferent to the glomerulus, a significant reorganization of the whole synaptic complex was observed, whereas the structural integrity of the glomerulus was remarkably well preserved.

Immunocytochemical visualization of the mGluR1a metabotropic glutamate receptor at synapses of corticothalamic terminals originating from area 17 of the rat.

Pre-embedding immunogold histochemistry was combined with Phaseolus vulgaris leucoagglutinin anterograde tract tracing in order to analyse the relationship between the subcellular localization of the GluR1a metabotropic glutamate receptors and the distribution of corticothalamic synapses in the dorsal lateral geniculate nucleus (dLGN) and the lateral posterior nucleus (LP) of the rat. The injection of the tracer into area 17 labelled two types of corticothalamic terminals: (i) the small boutons constituting the majority of the labelled fibres which form asymmetrical synapses both in the dLGN and LP; and (ii) the giant terminals typically participating in glomerulus-like synaptic arrangements and found exclusively in the lateral posterior nucleus. The small corticothalamic terminals often established synapses with mGluR1a-immunopositive dendrites, with immunometal particles concentrated at the periphery of their postsynaptic membranes.
