Chemopreventive potential of esculetin in 7,12-dimethylbenz(a)anthracene-induced hamster buccal pouch carcinogenesis.

7,12-Dimethylbenz(a)anthracene (DMBA)-induced hamster buccal pouch carcinogenesis is widely preferred to assess the tumor-inhibiting efficacy of the medicinal plants or their constituents. The present study explores the tumor-inhibiting potential of esculetin by utilizing the status of lipid peroxidation by products (thiobarbituric acid reactive substances), antioxidants (vitamin E, reduced glutathione, superoxide dismutase, catalase, and glutathione peroxidase), and phase I and phase II detoxification agents as biochemical end points and by using histopathological studies as well in DMBA-induced hamster buccal pouch carcinogenesis. Oral tumors developed in the buccal pouch were subjected to histopathological studies, and were confirmed as oral squamous cell carcinoma.

Assessment of Regeneration of Bone in the Extracted Third Molar Sockets Augmented Using Xenograft (CollaPlug Zimmer) in Comparison with the Normal Healing on the Contralateral Side.

Introduction: Alveolar bone resorption is a significant clinical problem. Bone loss in third molar region following extraction or surgical removal not only leads to periodontal problems in second molar region but also it may lead to some serious problems like increased incidence of angle fractures. In order to reduce the risks following third molar surgery, the socket should be augmented with bone grafts.

Accidental Perforation of Submental Flexometallic Tube.

Oral and maxillofacial surgeries associated with complications due to endotracheal tube (ETT) damage are being reported in literature increasingly. In this case, we report a rare case of accidental perforation of a flexometallic ETT intraoperatively during an orthognathic corrective surgery, in a 19-year-old female patient in whom submental intubation had been performed. The complication was managed conservatively as the tissue debris created during the osteotomy drilling occluded the damage and caused a good seal of the damage, with minimal leak, and no airway compromise.

Plasma and Urinary Type IV Collagen Levels for Early Detection of Nephropathy in Type 2 Diabetes Mellitus Patients.

Background: Diabetic nephropathy is a major complication with high morbidity and mortality, and leads to end stage renal disease (ESRD). Type IV collagen is the main component of the glomerular basement membrane (GBM) and the extracellular matrix. The thickening of the GBM is due to accumulation of type IV collagen and alterations in its structure and composition.
