To provide concise and brief important stereological application methods and techniques for estimating biological tissues. Stereology studies the quantity of biological tissue using little practice and the low price of counting and preparing tissue slices to obtain direct and accurate results. Since their establishment, the stereological techniques underwent much improvement, thus allowing more precise analysis of target structures using various approaches. Using stereological tools, advances in stereological techniques made the target tissues or organs represented by 2D instead of 3D dimensions. Process tools estimate volume, area and length. According to the exciting tissue and aims, the stereological tools perform differently. This review summarizes various stereological tools and techniques, providing brief information about the orientation method, slicer probe method, Delesse's principle, Cavalieri principle, disector, fractionator, nucleator, virtual cycloids and saucer, which are described in detail. 相似文献

AimTo investigate the relationship between BMI and blood pressure as this is of crucial interest in evaluating both public health and the clinical impact of the so-called obesity epidemic. METHODS: Data were gathered from 1899 children aged between 6 and 14 years, analysing and evaluating a possible relationship between BMI and systolic and diastolic blood pressure values for both girls and boys. Each child was classified on the basis of age- and sex-specific BMI percentile as normal weight (<85th percentile), overweight (95th percentile). RESULTS: In comparisons among ageBMI percentile groups, systolic and diastolic blood pressure values were higher in obese and overweight groups than in normal weight groups for both sexes. Although BMI among girls was higher than among boys in all three percentile groups, there were no significant differences between sexes with respect to blood pressure values.ConclusionThe present findings emphasize the importance of the prevention of obesity in order to prevent future related problems such as hypertension in children and adolescents. 相似文献
