Recent developments of a Ki67 antibody to recombinant parts of the Ki67 nuclear antigen have provided a marker for tumor proliferation. In the present study, biopsy specimens were obtained from 20 patents with squamous cell carcinoma of the oral cavity at various sites, who also received a regional neck dissection. The patients' mean age was 61 years.(More)
To overcome the sensitivity limit in immunoassays for small molecules (haptens), we established a noncompetitive immunoenzymometric assay (IEMA) format that can detect attomole-range hapten molecules. We selected 11-deoxycortisol (11-DC; Mr 346.5), a corticosteroid serving a diagnostic index for pituitary-adrenal function, as a model target hapten. A fusion(More)
In the developing chick heart, endothelial cells in the atrioventricular canal (AV) undergo a series of morphological changes and transform into cushion mesenchymal cells. In the present scanning electron microscopic study, we examined the abluminal surface features of the AV endothelium through an artificial window in the myocardial wall. The AV(More)
The effect of toothbrushing is plaque removal and gingival massage. However, intensive oral hygiene frequently results in gingival damage. The object of this study was to determine the damage to oral soft tissues resulting from three methods of brushing (roll, scrub, and bass method) and the use of toothbrushing with two different hardness (Hard: 10.2(More)
