Cemental annulations are easily countable in teeth from animals that have an exaggerated regular change of food intake from season to season. Although present in human teeth, cemental annulations are not always easy to count. A method for preparing human teeth for evaluation involving collection, identification, measuring, sectioning, cleaning, acid etching, staining, and mounting is reported. Sections 100-microns thick were stained with cresyl fast violet as a stain of choice and were photographed using standard light microscopic techniques as well as Nomarsky interference microscopy. Countability of annulations from photographic enlargements was evaluated. 相似文献

The records of two cytopathology laboratories, covering an aggregate of 33 years, were searched for pleural, peritoneal and pericardial fluids reported as containing cells of squamous cell carcinoma (SCC). This search embraced 9,297 serous fluids from 7,389 patients. Cells of SCCs were found in the fluids from only 46 patients, illustrating the infrequency of such a finding, with most of the SCC cells originating in primary neoplasms of the lung (16), female genital tract (8) or larynx (6). All of the recognized types of SCC cells were found in these fluids. Even so, SCC cells may be mistaken for cells of other neoplasms, such as adenocarcinoma and malignant mesothelioma. SCC cells in serous fluids should be identifiable if careful attention is paid to the morphologic features characteristic of SCC. 相似文献

Melanoma growth stimulatory activity (Mgsa) is a polypeptide mitogen and a possible autocrine growth factor for melanoma and other tumor cells. A restriction fragment length variant of Mgsa was followed in interspecific backcross mic Mgsa was localized between Afp and Gus on mouse chromoson 5, distal to known loci affecting skin pigmentation. 相似文献
