BACKGROUND Peripheral nerve repair is often complicated by fibroblastic scar formation, nerve dysfunction, and traumatic neuroma formation. Use of silicone may improve outcomes of these repairs. In this study, we tried to evaluate effectiveness of silicone gel on rats’ sciatic nerve repair, axon regeneration and scar formation around and in the nervous tissues. METHODS This experimental stud...

A case of mixed hepatoblastoma in a woman is described. A survey of the English literature reveals 13 cases acceptable as mixed hepatoblastoma; these have been described and published under a variety of names. Difficulties in nomenclature and the histology of these cases are discussed. Diagnosis depends on the identification of both malignant mesenchymal and malignant epithelial elements. The f...

Background and Objective: Smoking can be associated with the decreasing gingival blood flow and epithelial changes. The aim of this study was to evaluate the histopathological changes of gingival epithelium and connective tissue in smokers. Methods: The study was case-control. Sixty male patients (28 smokers and 32 nonsmokers) suffering chronic periodontitis were participated...

-The present study was designed to establish whether there are changes in hemidesmosomal distribution during defined stages of chemical carcinogenesis in hamster cheek-pouch epithelium. 0-5%0 DMBA in liquid paraffin was applied thrice weekly to hamster pouches, and tissue samples were obtained at regular intervals and assigned to hyperplastic, dysplastic and carcinomatous groups on the basis of...

Need for regeneration and repair of nasal tissues occurs as a consequence several pathologies affecting the nose, including, but not limited to infective diseases, traumas tumor resections. A platform tissue was set up using poly(vinyl alcohol)/gelatin sponges with 20%–30% (w/w) gelatin content be used scaffolds, their intrinsic hydrophilic, cell adhesive shape recovery properties. We propose m...
