Comparative evaluation of eosinophils in normal mucosa, dysplastic mucosa and oral squamous cell carcinoma with hematoxylin-eosin, Congo red, and EMR1 immunohistochemical staining techniques.

Background: Oral squamous cell carcinoma is the most common malignant lesion of the oral cavity, and it involves various molecular mechanisms. The development of oral squamous cell carcinoma is influenced by the host immune cells, such as eosinophils. The present study was conducted to compare the presence of eosinophils in normal mucosa, dysplastic mucosa, and oral squamous cell carcinoma by -hematoxylin- eosin staining, Congo red staining, and epidermal growth factor-like (EGF-like) module containing a mucin-like hormone receptor1 (EMR1) immunohistochemical marker.

Effects of diclofenac and celecoxib on osteoclastogenesis during alveolar bone healing, in vivo.

Background: OSTEOCLASTOGENESIS IS COORDINATED BY THE INTERACTION OF MEMBERS OF THE TUMOR NECROSIS FACTOR (TNF) SUPERFAMILY: Receptor activator of nuclear factor-κB ligand (RANKL) and Osteoprotegerin (OPG). The aim of this study was to compare the effect of two different types of non-steroidal anti-inflammatory drugs (NSAIDs) on the RANKL/OPG balance during the healing of the alveolar process.

Materials And Methods: This was an experimental study, carried on 45 male Wistar rats (200 ± 25 g, 8-10 weeks old).
