Stereological quantitation of Leydig and Sertoli cells in the testis from young and old men
Peter M. Petersen, Bente Pakkenberg
Izvirni znanstveni članek
Oznake:
One of the newer stereological methods, the optical fractionator, was applied to the study of the effects of ageing on the human testis. The estimated totalnumber of Sertoli and Leydig cells per testis in men younger than 30 years were 430x10(6) (CV = SD/mean = 0.35) and 117x10(6) (CV = 0.53), respe ...

Neuron and glial cell numbers in the mediodorsal thalamic nucleus in brains of schizophrenic subjects
Rune Damgaard Nielsen, Maja Abitz, Bente Pakkenberg
Izvirni znanstveni članek
Oznake:
Several stereological studies of schizophrenic subjects have shown reduction in both the total number of neurons and in the total volume of the mediodorsalthalamic nucleus (MD). This is in contrast to other studies in thatno differences have been found. Using systematic random sampling and an optica ...

Efficient and unbiased tools for quantitating Leydig and Sertoli cells in the testis from testes biopsies
Bente Pakkenberg, Peter M Petersen, Aleksander Giwercman, Hans J Gundersen
Izvirni znanstveni članek
Oznake:
The possibility of obtaining reliable estimates of the total number of Sertoliand Leydig cells from biopsies by use of the optical fractionator method was tested. The total number of Sertoli and Leydig cells was 522x106 (CV=0.27) and 89x106 (CV=0.34), respectively, when sampling in the entire testis ...

Stereology of neuronal connections (myelinated fibers of white matter and synapses of neocortex) in human brain
Yong Tang, Jens Randel Nyengaard, Bente Pakkenberg, Hans Jørgen G. Gundersen
Izvirni znanstveni članek
Oznake:
Unbiased stereological sampling and counting techniques for estimating the total length, total volume and diameter distribution of myelinated nerve fibers in white matter and the total number of synapses in neocortex of human autopsy brains were described. Uniform random sampling of tissues from ent ...

Total cell number in fetal brain
Grethe Badsberg-Samuelsen, Nenad Bogdanović, Henning Laursen, Niels Graem, Joergen Falck-Larsen, Bente Pakkenberg
Izvirni znanstveni članek
Oznake:
In this study the material comprises brains from three aborted fetuses and twofullterm infants who died at birth. The gestational ages ranged from the 22nd week to term. All cases were without malformations, known chromosomal abnormality, hydrops, and systemic infections, and all had normal birth we ...
