The morphometric differences between the urothelial cells (wet-fixed Papanicolaoustained) in the voided urine of 2 patients with low grade and high grade bladder tumours were measured. The morphometrical data of this learning set resulted in a cytomorphometrical classification rule, which was applied to a test set of 21 cases with low grade and high grade bladder tumours. The results of the cyt...

anatomical and histomorphometrical study of sheep’s thymus was conducted by 75 apparently healthy fetuses that collected from urmia’s industrial slaughterhouse. after anatomical study, the samples were fixed in 10% formal saline, passaged and histological paraffin sections prepared in 5-7 μm in thickness, and by h&e; method stained. histomorphometrical study performed by graded and latticed len...

This research was carried out to define the morphological features of infundibulum and magnum in turkey and pigeon. For this purpose, a total of 10 adult healthy turkey (No=5) and pigeon (No= 5) were used. After dissecting, infundibulum and magnum of each specimen was separated by incision and fixed in 10% buffered formalin. For histological studies, after tissue preparation and staining with H...

Surface topography has significant influence on good and fast osseointegration of biomedical implants. In this work, ultrasonic shot peening was conducted to modify titanium to produce nanograined (NG) surface. Its ability to induce new bone formation was evaluated using an in vivo animal model. We demonstrated that the NG surface enhanced osteoblast adhesion, proliferation, differentiation, an...

In histomorphometrical investigations of bone tissue modeling around screw-shaped implants, the manual measurements of bone area and bone-implant contact length around the implant are time consuming and subjective. In this paper we propose an automatic image analysis method for such measurements. We evaluate different discriminant analysis methods and compare the automatic method with the manua...

Objective This study aimed to assess the effects of fluoxetine, a selective serotonin reuptake inhibitor, on the formation of the periodontal ligament during pregnancy and lactation in rat pups. Material and Methods Twelve pregnant rats of Wistar lineage were divided into four study groups. In the control group, 0.9% sodium chloride solution was administered orally, throughout the entire peri...
