This study has been designed to estimate the volume fraction of the brain ventricles volume to total brain volume and to correlate them with gender and age in normal subjects. Cranial computed tomography (CT) images of 80 normally evaluated subjects (five female and five male for each decade) were selected from 1,073 CT examinations. The volumes of total brain, cerebral aqueduct, fourth, third,...

Platelet-rich plasma (PRP) as a source of growth factors may induce tissue repairing and improve fibrosis. This study aimed to assess the effects of PRP on kidney regeneration and fibrosis in gentamicin (GM)-induced nephrotoxicity rat model by stereological study. Thirty-two male rats were selected. Nephrotoxicity was induced in animals by administration of GM (80 mg/kg/daily, intraperitoneally...

Systematic sampling is widely used in stereology. Practical stereology is commonly based on measurements on serial sections and grids of quadrats, cycloids or points superimposed on sections. The precision of estimators based on systematic measurements can be assessed, using the so-called transitive methods due to [9]. The use of the transitive methods in stereology has been discussed in a seri...

OBJECTIVE Stereological evaluation of the concentration of type I and III collagen fibers in the urethral tissue of rats subjected to simulated labor and oophorectomy. To compare the concentrations of collagen between oophorectomized and non-oophorectomized rats. MATERIAL AND METHOD Sixty adult Wistar rats were divided into six groups. A group made up of virgin rats was used as control group ...

the aim of the present study was stereological evaluation of testes of azoospermic animal model using busulfan in rat. three groups of male adult rats were used in this study. the first group was injected by single dose of busulfan (10 mg kg-1) and their testes were removed on day 35 post injection. the second group received double doses of busulfan with 21 days interval and their testes were r...

Objective(s) High blood glucose induces molecular, cellular, morphological and behavioral changes in the brain. Metabolic disturbances, contribute to the hippocampus injury and development of partial focal seizures. The aim of this study was to investigate the effects of infantile repeated hyperglycemia on neuronal density of hippocampal CA3region in newborn Wistar male rats and its effect on ...
