The aim of the present study was to determine, by kariometric parameters, the influence of phenytoin, as teratogen, on the epithelial layer of choroid plexus in rats fetuses, using single daily dose ( 75 mg Kg-1 bd.wt.), during gestation GD9 to GD11, and lowest total dose used orally (225 mg Kg-1), to the best of our knowledge. In some of experimental studies in animals, the anticonvulsant drug phenytoin were administered in embriotoxic daily doses (100-1500 mg Kg-1 bd.wt.) increasing concentrations up to 20 times the human therapeutic plasma concentration. There is a significant lack of information regarding the embriotoxicity in pregnancy of these drug, phenytoin, in low doses. Phenytoin was administered in a single daily dose (75 mg Kg-1 bd.wt.) to... |

The present study has the aim to describe morphologically, morphometrically and stereologically some changes in the tongue epithelium of rat fetuses under the effect of cyclosphosphamide. This drug was used in a single 6mg/kg according to the body weight in the tenth pregnancy day while the control group received equal dosage of saline solution by the same duct and in the same day of pregnancy. The fetuses were plunged into fixed solution of Bouin for five days and the heads of then were divided and blocked in paraffin. Histological sections of six-micrometer thickness were performed and then colored with hematoxilin and eosin. It was used morphometrical and stereological analysis after the morphological study. The data were submitted under the... |

The tongue is one of the most likely places for the primary squamous cell carcinoma (SCC) to arise in the western world.This work intends to do a morphometric evaluation of the cellular nucleus, as well as a morphometric analysis of the nucleolar organizer regions (NORs). The biopsy specimen was removed from patients with tongue SCC, staged T2N0M0, before they underwent treatment. They were, then, subject to hemiglossectomy and supraomohyoid neck dissection (SOHND) and presented different clinical evolution. According to that, they were subdivided in three groups: Group A, control group, formed by patients without tongue neoplasm (the histopathologic specimen was obtained from the Department of Pathology at Hospital de Base and Faculdade de Medicina de Sao... |
