Morphologic changes in the vesical transition epithelium of alcoholic rats

Few studies are available about the effect of alcohol on the epithelium of the urinary bladder. In the present investigation we studied the ultrastructure of the vesical transition epithelium of normal rats and of rats submitted to experimental chronic alcoholism. Adult rats were submitted to experimental chronic alcoholism by the ingestion of sugar cane liquor. The vesical epithelium was examined after 60, 120, 180 and 240 days of alcohol treatment by transmission electron microscopy. Surface cells presented nuclear and cytoplasmic changes and marked cellular desquamation. There was an increase in multivesicular bodies and lysosomes suggesting cell degeneration. Mast cell infiltration was observed, possibly related to increased epithelial sensitivity. Intercellular spaces were frequently observed. The transition epithelium of the urinary bladder was found to be sensitive to the action of alcohol, as demonstrated by the changes in the components of the blood-urine barrier, the greater sensitivity to inflammation, the increase in cell desquamation and the greater recycling of the apical membrane and of the fusiform vesicles of surface cells observed in alcoholic rats.

Picrosirius-polarization staining method as an efficient histopathological tool for collagenolysis detectin in vesical prolapse lesions

The Picrosirius-polarization method has been indicated as a selective histochemical stain for collagen detection in tissue sections. This method can also be of value for studying collagen degradation given that, under polarized light, collagen displays birefringence due to its molecular order. The aim of this study is to highlight this staining method as an additional instrument for a rapid and excellent confirmatory diagnosis of the presence of collagenolysis in connective tissue in the vaginal wall with vesical prolapse lesion, in tissue sections. Dramatic changes in collagen morphology were found in vaginal mucosa in vesical prolapse disorder: they were weakly stained by Sirius red and under polarized light appeared as thin, pale (weakly birefringent), greenish, and with fibers more scattered, while the histoarchitecture of the organ showed a disrupted appearance. Thus, in the present study, we showed in vaginal mucosa in the vesicle prolapse that corroded collagenous framework appears as fragmentary and irregularly separated collagenous structures, that are weakly birefringent, corresponding to a molecular disorganization of these fibers caused by collagenolysis.

Sensibilidade do colo dental. Uma nova alternativa terapêutica.

The cervical hypersensitivity tooth was analysed and treated by application of a varnish with high fluoride ions content (Duraphat) and of a glass ionomer cement usually indicated to cavity lining (XR-ionomer-Kerr). This technique was applied in sixty-seven teeth of Clinic Graduation patients (Faculdade de Odontologia de Araçatuba) and demonstrated a high index of satisfactory results. The clinical findings of this study relate that, this technique is more one method of choose by clinicians.

Evolução no diagnóstico citológico do câncer de colo uterino - Novas tecnologias para o rastreamento citológico cervical

The cancer of the uterine cervix remains a serious public health problem in developing countries with low social-economic conditions. Papanicolaou smear has been used to screen women for cervical cancer since 1940, and it is widely recognized as an effective method for preventing cervical cancer. In Brazil, conventional Papanicolaou is the most common method used in diagnosis cytopathological routine, involving the morphological cell analysis by microscopic examination of cervical samples smeared on glass slides. On the other hand, the liquid cytology is an advantageous method whose specimen collected is put into a fluid alcohol based to guarantee the potential use of residual cellular material in cytobrush. Moreover, this method permits additional diagnostic studies, preserving the morphological cell features as the conventional one does. The aim of the present study was report the historical evolution of different cervical cytologic tests, emphasizing the advantages and disadvantages between conventional Papanicolaou method and new technologies in liquid based cytology.
