Stereological studies were performed on 27 pairs of adrenal glands of human fetuses (9-38 weeks of intra-uterine development). Medullary chromaffin cells were identified by immunostaining for chromogranin-A. The volume of adrenal medulla, average cell volume, and the number of chromaffin cells were calculated. The volume of adrenal medulla increased slowly up to the 20th week and afterwards it ...

Unbiased stereology is a method for accurately and efficiently estimating the total neuron number (or other cell type) in a given area of interest(1). To achieve this goal 6-10 systematic sections should be probed covering the entire structure. Typically this involves processing 1/5 sections which leaves a significant amount of material unprocessed. In order to maximize the material, we propose...

background wound healing is a dynamic process with inflammatory response and oxidative reaction in the damaged area. alpha ointment (ao) and arnebia euchroma (arnebia) are herbal medicines with antioxidant and anti-inflammatory effects that can be used as wound healing agents. ao is a commonly used ointment while arnebia is a newly introduced one. objectives we aimed to compare the effects of a...

Stereology applied on histological sections is the 'gold standard' for obtaining quantitative information on cancellous bone structure. Recent advances in micro computed tomography (microCT) have made it possible to acquire three-dimensional (3D) data non-destructively. However, before the 3D methods can be used as a substitute for the current 'gold standard' they have to be verified against th...

OBJECTIVE The aims of this study were to compare distinct brain frontal lobe parcellation methods across 90 brain magnetic resonance imaging scans and examine their associations with cognition in older age. METHODS Three parcellation methods (Manual, FreeSurfer, and Stereology) were applied to T1-weighted magnetic resonance imaging of 90 older men, aged ∼ 73 years. A measure of general fluid ...
