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.

Glucocorticoid-induced apoptosis in lymphoid organs is associated with a delayed increase in circulating deoxyribonucleic acid.

Pathological processes like cancer, chronic inflammation and autoimmune phenomena, all of which involve massive cell death, are associated with significant increases in circulating DNA. In order to clarify whether massive apoptosis occurring under physiological circumstances also causes DNA release into the circulation, we correlated the time-course of dexamethasone-induced intra thymic cell apoptosis with plasma DNA dynamics in rats. Animals were given 10 mg/l dexamethasone in their drinking water for up to 7 days.

[Granular cell tumor of the esophagus. Morphological and immunohistochemical study].

Unlabelled: Granular cell tumor or Abrikosoff's tumor is an infrequent and usually benign neoplasm which is found predominantly in the head and neck region, especially in the tongue. Its esophageal location is unusual, where most of them present as small, well circumscribed lesions which follow a benign course. Because of its low incidence in this site (less than 200 cases having been reported until 1993), we report two cases of esophageal granular cell tumors, both of them in male patients.

[Idiopathic portal hypertension with splenic infarct. An unreported complication].

We present a case of Idiopathic Portal Hypertension (IPH) with Splenic infarct in a 23-year-old female. She was referred to the hospital because of enlargement of liver and spleen. A computed axial tomography revealed Splenic infarct.
