Morphologic effects of hypervitaminosis a on rat submandibular gland

Young male Sprague-Dawley rats were fed oral supplements of vitamin A; either a subtoxic dose of 5000 i.u./day for 16 weeks (10 animals), or a toxic dose of 15,000 i.u./day for 16 days (5 animals). High-dose animals exhibited signs of acute toxicity; low-dose animals demonstrated only less weight gain than controls. Vitamin A sera and liver levels evidenced intoxication. Light and electron microscopy were conducted upon acini, intercalated ducts, and striated-granular ducts of the submandibular gland. Acinar cells evidenced rough endoplasmic reticulum clefting and hyperplasia of both rough endoplasmic reticulum and Golgi apparatus similar to changes produced by pilocarpine or isoproterenol and interpreted as hyperactivity. Also increased were the number of degenerating acinar cells. Striated-granular duct cells were similar to controls except for increased cellular degeneration. Intercalated ducts appeared unaffected. Abnormalities were more pronounced in short-term, toxic hypervitaminosis A than long-term, subtoxic hypervitaminosis A.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/34016/1/0000291.pd

Odontogenic tumors and giant cell lesions of jaws - a nine year study

<p>Abstract</p> <p>Objectives</p> <p>A definite geographic variation has been observed in the frequency of odontogenic tumors and giant cell lesions of the jaws reported from different parts of the world. However, there are a few studies on these lesions, especially giant cell lesions, reported from India. Hence, this study was designed to provide a demographic data on the odontogenic tumors and giant cell lesions reported from our institute located in the city of Hyderabad. Hyderabad is the capital city of the southern state of Andhra Pradesh in India. A retrospective analysis of odontogenic tumors and giant cell lesions of jaws reported in our institute between the years 2000 and 2009 was done and this data was compared with previous reports from different parts of the world and India.</p> <p>Methods</p> <p>Biopsies of the lesions received between the years 2000 and 2009 were reviewed and patient's history, clinical, radiological and histopathological characteristics were analyzed.</p> <p>Results</p> <p>A total of 77 biopsies were received during the nine year study period. These lesions were more frequently seen in the males, in a younger age group and showed a predilection for the mandible. Most of them presented as radiolucent, slow growing and painless lesions. Ameloblastomas (71.4%) constituted the majority of odontogenic tumors while central giant cell granulomas (7.8%) constituted the majority of giant cell lesions.</p> <p>Conclusion</p> <p>These lesions showed a definite geographic variation with ameloblastomas being the most common odontogenic tumors and odontomas being relatively rarer lesions in our region.</p
