  abstract  = {Ultrastructural changes including reduced electron density, reduction in polysemes and cisternae of rough endoplasmic reticulum occur in the cytoplasrn of endothelial cells and pericytes in the cerebellar cortex of senile virgin female Han: WIST-rats in cornparison to 3-month old virgin rats. Processes of pericytes cover less of the capillary surface in the cerebellar cortex of senile rats; moreover, arithmetic and harmonic mean thickness of the endothelium and relative volume of mitochondria in endothelial cells and pericytes are reduced, w hereas the luminal diameter of the capillaries, harmonic and arithmetic mean thickness of pericytes and their processes and of the basal laminae between endothelial cells and astrocytes (abbreviated BAL 1), pericytes and astrocytes (BAL 2) and endothelial cells and pericytes (BAL 3) increase. The increase in harmonic mean thickness of the basal laminae is statistically significant (α<=0.05) and compensates for a decrease in thickness of capillary endothelium. Consequently, the total barrier mass and thickness of cerebellar cortical capillaries in senile animals is higher than in young individuals.},

  abstract  = {The total cortical and striatal neurone and glial numbers were estimated in five cases of Huntington's disease (three males, two females) and five ageand sex-matched control cases. Serial 500-l-lm-thick gallocyanin-stained frontal sections through the left hemisphere were analysed using Cavalieri's principle for volume and the optical disector for cell density estimations. The average cortical neurone number of five controls (mean age 53±13 years, range 36-72 years) was 5.97x 109±320x 106 , the average number of small striatal neurones was 82 X 106± 15.8 X 106• The left striatum (caudatum, putamen, and accumbens) contained a mean of 273 X 106±53 X 106 glial cells (oligodendrocytes, astrocytes and unc1assifiable glial profiles). The mean cortical neurone number in Huntington's disease patients (mean age 49±14 years, range 36-75 years) was diminished by about 33 \% to 3.99x109±218x106 nerve cells (P ::;:::: 0.012, MannWhitney V-test). The mean number of small striatal neurones decreased tremendously to 9.72 X 106 ± 3.64 X 106 (-88 \% ). The decrease in total glial cells was less pronounced (193 X 106±26 X 106) but the mean glial index, the numerical ratio of glial cells per neurone, increased from 3.35 to 22.59 in Huntington's disease. Qualitatively, neuronal loss was most pronounced in supragranular layers of primary sensory areas (Brodmann's areae 3,1,2; area 17, area 41). Layer HIc pyramidal cells were preferentially lost in association areas of the temporal, frontal, and parietal lobes, whereas spared layer IV granule cells formed a conspicuous band between layer IH and V in these fields. Methodological issues are discussed in context with previous investigations and similarities and differences of laminar and lobar nerve cellloss in Huntington's disease are compared with nerve cell degent-ration in other neuropsychiatric diseases.},

  abstract  = {Background: Panic disorder is common (5\% prevalence) and females are twice as likely to be affected as males. The heritable component of panic disorder is estimated at 48\%. Glutamic acid dehydrogenase GAD1, the key enzyme for the synthesis of the inhibitory and anxiolytic neurotransmitter GABA, is supposed to influence various mental disorders, including mood and anxiety disorders. In a recent association study in depression, which is highly comorbid with panic disorder, GAD1 risk allele associations were restricted to females. Methodology/Principal Findings: Nineteen single nucleotide polymorphisms (SNPs) tagging the common variation in GAD1 were genotyped in two independent gender and age matched case-control samples (discovery sample n = 478; replication sample n = 584). Thirteen SNPs passed quality control and were examined for gender-specific enrichment of risk alleles associated with panic disorder by using logistic regression including a genotype6gender interaction term. The latter was found to be nominally significant for four SNPs (rs1978340, rs3762555, rs3749034, rs2241165) in the discovery sample; of note, the respective minor/risk alleles were associated with panic disorder only in females. These findings were not confirmed in the replication sample; however, the genotype6gender interaction of rs3749034 remained significant in the combined sample. Furthermore, this polymorphism showed a nominally significant association with the Agoraphobic Cognitions Questionnaire sum score. Conclusions/Significance: The present study represents the first systematic evaluation of gender-specific enrichment of risk alleles of the common SNP variation in the panic disorder candidate gene GAD1. Our tentative results provide a possible explanation for the higher susceptibility of females to panic disorder.},

The membrane- bounded pigment is composed ofthree elements: 1) electron-lucent homogeneaus droplets, 2) a granular matrix and 3) intensely osmiophilic patches. The proportians ofthese three components vary between cell types and one can grossly differentiate a neuronal and a gliallipofuscin. The lipofuscin granules of stellate and perivscular cells are different from lipofuscin of other cerebellar neurons and glia. lt can be concluded from these morphological observations that each cerebellar cell type has its distinct lipofuscin.},

  abstract  = {The quantitative postnatal changes of the cerebella of 65 Wistar rats aged 2-120 days have been examined. The cerebellar volume increases in two phases: The first phase lasts from birth to the seventh postnatal week. The second phase begins ten weeks post parturn and lasts for a Ionger period than the first phase. The cerebellar surface increases continuously from birth to the end of the seventh week. The volume of the external granular layer is maximal when the organ grows rapidly. The external granular layer has nearly disappeared 24 days after birth; the volume of the interaal granular layer is maximal at this time. Later on, the volume and the width of the interaal granular layer decrease. Myelinization of the cerebellar fibers and growth of the molecular layer run parallel to this decrease. The second late, but protracted growth of the cerebellum, ten weeks after birth, is due to an increase of the molecular and medullary layer. These findings are in good accord with histological, histochemical, and ultrastructural observations of other authors.},

  abstract  = {The total nerve cell numbers in the right and in the left human entorhinal areas have been calculated by volume estimations with the Cavalieri principle and by cell density determinations with the optical disector. Thick gallocyanin-stained serial frozen sections through the parahippocampal gyrus of 22 human subjects (10 female, 12 male) ranging from 18 to 86 years were analysed. The laminar composition of gallocyanin (Nissl)-stained sections could easily be compared with Braak's (1972, 1980) pigmentoarchitectonic study, and Braak's nomenclature of the entorhinal laminas was adopted. Cellsparse laminae dissecantes can more clearly be distinguished in Nissl than in aldehydefuchsin preparations. These cell-poor dissecantes, lamina dissecans extema (dis-ext), lamina dissecans 1 (dis-1) and lamina dissecans 2 (dis-2), were excluded from nerve cell nurober determinations. An exact delineation of the entorhinal area is indispensable for any kind of quantitative investigation. We have defined the entorhinal area by the presence of pre-alpha ceil clusters and the deeper layers of lamina principalis externa (pre-beta and gamma) separated from lamina principalis interna (pri) by lamina dissecans 1 (dis-1). The human entorhinal area is quantitatively characterized by a left-sided (asymmetric) higher pre-alpha cell number and an age-related nerve cell loss in pre as well as pri layers. At variance with other CNS cortical and subcortical structures, the neuronal number of the entorhinal area appears to decrease continuously from the earliest stages analysed, although a secular trend has to be considered. The asymmetry in pre-alpha cell number is discussed in the context of higher human mental capabilities, especially language.},
