Objective. To evaluate trophoblastic cell proliferation and angiogenesis in tubal pregnancy assessed by immunohistochemical study and their correlation with an average variation of β -hCG in an interval of 48 hours before surgery. Methods. A prospective study was conducted on 18 patients with a diagnosis of tubal pregnancy. The patients were divided into two groups of ectopic pregnancy of which...

The intensities of immunofluorescence in nuclei stained by an antiserum specific for the DNA adduct N-deoxyguanosin(8-yl)aminofluorene (dG-8-AF), were quantified by microfluorometry in frozen liver sections from male Fischer rats fed 2-acetylaminofluorene (AAF). Results of previous studies demonstrated that dG-8-AF is the predominant adduct (80-100%) formed in livers of rats fed AAF continuousl...

The geometrical concept of the Voronoi diagram was used to create an image filter providing a “stained glass” or mosaic effect on an image. The Voronoi diagram was calculated by exploiting its dual relationship with the Delaunay triangulation, which was in turn calculated using a randomized incremental algorithm and stored in a DCEL. Various methods were tried for selecting the points, includin...

The bright pigments of cave pictures in Spain have been preserved from Paeleolithic times by the accidental formation of a surface film of calcite (Kuhn, 1952), and since then many glazes have been used deliberately for the protection of colours. The idea of varnishing glass slides is not novel, but practical difficulties concerning preparation, pH, and especially viscosity, have discouraged it...

BACKGROUND & OBJECTIVES Making centrifuged deposit smears from sputum to detect acid-fast bacilli (AFB) is considered hazardous. We carried out this study to stain the centrifuged deposits with carbol-fuchsin in sputum containers and to decolourize and counterstain their smears made on glass slides. METHODS The centrifuged deposits of 180 sputum samples from pulmonary tuberculosis patients we...

OBJECTIVE Assess the association between meconium-stained amniotic fluid and chorioamnionitis or endometritis in term pregnant women. MATERIAL AND METHOD A five-year retrospective study was undertaken between January 1, 1999 and December 31, 2003. One thousand seventy-nine pregnant women who delivered at the Department of Obstetrics & Gynecology, Phramongkutklao Hospital were included in the ...
