The differential diagnosis between pleomorphic adenoma, the most common salivary gland neoplasm, microscopically, and two other common salivary gland neoplasms, meaning adenoid cystic carcinoma and mucoepidermoid carcinoma, is difficut.The purpose of this study was to determine the differences between pleomorphic adenoma, adenoid cystic carcinoma and mucoepidermoid carcinoma regarding the stain...
abstract: introduction & objective: the hippocampal formation is a part of limbic system that plays an important role in memory and learning. the hippocampus is divided into three subfields: ca1, ca2 and ca3. in addition to pyramidal neurons and interneurons, the astrocytes play important roles in hippocampus, probably in memory and learning. in fact, learning needs some instruments for informa...
Renovascular lesions of lupus nephritis (LN) were classified into five categories by D'Agati in Heptinstall's Pathology of the Kidney, with thrombotic microangiopathy (TMA) and clinical thrombotic thrombocytopenic purpura (TTP) being combined. We encountered 2 cases with histological LN (class III and lass V), and they presented with clinical features of TTP, such as acute renal failure, microa...
BACKGROUND AND PURPOSE Mechanical denudation of the endothelium of the carotid artery in animals produces a nonocclusive thrombus, but the brains of these animals have not been examined for the presence of embolic stroke. METHODS The endothelium of the right carotid artery of 16 Wistar rats was denuded using a balloon catheter. Phosphotungstic acid hematoxylin (PTAH) staining and scanning ele...
BACKGROUND Epistaxis is an important emergency that can sometimes be life threatening without effective intervention. Persistent and recurrent bleeding can lead to aspiration, hypotension, hypoxia, or even severe and mortal cardiovascular complications. Providing prompt hemostasis is important, and the hemostatic method used must be easily and locally applicable, efficient, and inexpensive. O...
The present study compared intracytoplasmic inclusion bodies in the locus ceruleus (LC) of mouse with protein bodies in the LC of human. Phosphotungstic acid-hematoxylin (PTAH) and the Mallory method were used as the anionic stains. The inclusion bodies and protein bodies, which stained with PTAH and the Mallory method in the brain, contain proteins that appear to belong to the same family. Alt...
BACKGROUND Increase of blood pressure is accompanied by functional and morphological changes in the vascular wall. The presented study explored the effects of curcuma and black pepper compounds on increased blood pressure and remodeling of aorta in the rat model of experimental NO-deficient hypertension. METHODS Wistar rats were administered for 6 weeks clear water or L-NAME (40 mg/kg/day) di...
Fifty-two subcutaneous tumours associated with microchip were collected from three carcinogenicity B6C3F1 mice studies. Two of these 52 tumours were adenocarcinoma of the mammary gland located on the dorsal region forming around the chip. All the other 50 were mesenchymal in origin and were difficult to classify on morphological grounds with haematoxylin-eosin. These sarcomas were investigated ...
