Mucoepidermoid carcinoma (MEC) corresponds to 5-12% of all salivary gland tumours, and is classified as low, intermediate or high grade. Traditionally, immunohistochemistry was considered as the complementary tool for diagnosis of salivary gland neoplasia. Lectin histochemistry has also been increasingly used in recent years. In this work, lectins were used as histochemical markers for normal a...
The growing interest in glycoconjugates expressed and released by the epithelium of the intestinal mucosa is tightly related to the multiple functional roles attributed to sialic acid and its derivatives. In the present work, biotin and HRP conjugated lectins were used to detect the sialylation pattern and to identify specific structural features of sialoderivatives in the rat colon. In particu...
The nasal septa of fetal rabbits at 26 days of gestation were harvested by cesarean section of the does while under anesthesia and then exposed to Bordetella bronchiseptica or its lipopolysaccharide (LPS) for periods of 2 and 4 hours. A total of 240 explants were used. The tissues were examined using the Hematoxylin & Eosin technique. Then, semithin sections (0.5 μm) were stained with toluidine...
introduction: studies have shown that opiates cause disorders in fertilization and accessory reproductive glands in animals. on the other hand studies have shown important role of glycoconjugates in sperm epididymal maturation. lectins can detect glycoconjugates with specific terminal glucose molecules. therefore this study was conducted to assess the possible effects of opiates on these import...
The nasal cavity of a rodent is lined by an epithelium organized into distinct regional domains responsible for specific physiological functions. Aggregates of nasal lymphoid tissue (NALT) located at the base of the nasal cavity are believed to be sites of induction of mucosal immune responses to airborne antigens. The epithelium overlying NALT contains M cells which are specialized for the tra...
Using lectin histochemistry, we have previously shown that there are alterations in the distribution of glycoconjugates in the tail bud of chick embryos that parallel the developmental sequence of the caudal axis. If glycoconjugates or the cells bearing them play a role in caudal axial development, then, restriction of their availability by binding with lectins would be expected to produce abno...
