Development of a database for cervical cytology reports.

Background: Cervical cancer is an important cause of female mortality. Its incidence, however, has been drastically reduced by early detection using the Papanicolaou screening method. As a result of the widespread use of this method, a large amount of cytological information has to be stored, printed and handled efficiently.

Comparative study of DNA synthesis and nucleolar organizer regions of sinusoid littoral cells in mouse regenerating liver.

Variations in DNA synthesis (DNAs) and Nucleolar Organizer Regions (NORs) were studied in the littoral cell population from regenerating liver of C3HS inbred mice standardized for periodicity analysis. Immunohistochemical detection of Bromodeoxyuridine (BrdU) with a monoclonal antibody and silver staining of NORs (AgNORs) were assessed by means of a digital image analysis system in histological sections. Tissue samples were obtained every four hours from the 30th to the 54th hours after a partial hepatectomy.
