The present article reviews the relevant stereological estimators for obtaining reliable quantitative structural data from the lungs. Stereological sampling achieves reliable, quantitative information either about the whole lung or complete lobes, whilst minimising the workload. Studies have used systematic random sampling, which has fixed and constant sampling probabilities on all blocks, sect...

objective(s):the hippocampus has been implicated in pathophysiology of schizophrenia. prenatal stress is a contributing risk factor for a wide variety of neuropsychiatric diseases including schizophrenia. this study examined long-term effects of prenatal restraint stress on the stereological parameters in the cornu ammonis (ca) of adult male rats as an animal model of schizophrenia. materials a...

objective(s) in recent years concerns have been raised regarding the incidence of male reproductive disorders from exposure to endocrine disruptors. so, chronic effects of di(2-ethylhexyl)phthalate were studied on histological and stereological structure of testis in adult wistar rats. materials and methods thirty two adult wistar rats were randomly divided in four equal experiment groups; oil ...

BACKGROUND Digital image analysis (DIA) enables better reproducibility of immunohistochemistry (IHC) studies. Nevertheless, accuracy of the DIA methods needs to be ensured, demanding production of reference data sets. We have reported on methodology to calibrate DIA for Ki67 IHC in breast cancer tissue based on reference data obtained by stereology grid count. To produce the reference data more...

Neuronal injury and neurodegeneration are the hallmark pathologies in a variety of neurological conditions such as epilepsy, stroke, traumatic brain injury, Parkinson's disease and Alzheimer's disease. Quantification of absolute neuron and interneuron counts in various brain regions is essential to understand the impact of neurological insults or neurodegenerative disease progression in animal ...

wounds and wound healing have always been one of the most important subjects that experimental researches were dedicated to. simvastatin has been used for long as a common lipid lowering agent which was reported to have some pleiotropic effects such as antioxidation, anti-inflammation and immunomodulation. in this study we aimed to determine the effect of simvastatin on wound healing process in...

Quantitative data on lung structure are essential to set up structure-function models for assessing the functional performance of the lung or to make statistically valid comparisons in experimental morphology, physiology, or pathology. The methods of choice for microscopy-based lung morphometry are those of stereology, the science of quantitative characterization of irregular three-dimensional ...
