The expression of transferrin receptor by normal, pregnant and benign hyperplastic breast lesions and by breast carcinomas has been investigated immunohistochemically using two monoclonal antibodies directed against the receptor. Unlike a previous immunohistological study in which staining was confined to malignant breast, transferrin receptor has been(More)
Cytogenetic analysis of an extraskeletal myxoid chondrosarcoma revealed a der(16)t(1;16)(q21;q13) in addition to the t(9;22)(q22;12) described as characteristic for this chondrosarcoma clinicohistopathologic subtype. An identical der(16) has been identified as the most common secondary structural aberration in Ewing's sarcoma and alveolar rhabdomyosarcoma.
The utilization of [3H] sugars and leucine by non-malignant and malignant human breast has been assessed using an organ culture technique with subsequent tissue autoradiography. The uptake of sugars by normal and hyperplastic breast was generally constant, with some differences observed in the utilization of galactose by acini of normal and hyperplastic(More)
2,4-dichlorophenoxyacetic acid and its derivatives (collectively known as 2,4-D) are herbicides used to control a wide variety of broadleaf and woody plants. The genetic toxicity of an ester (2,4-D 2-butoxyethylester) and two salts (2,4-D isopropylamine and 2,4-D triisopropanolamine) was investigated in cultured mammalian cells. The end points used were the(More)
The feasibility of comparative quality assessment studies in immunocytochemistry was examined. The reactions of three CD15 antibodies--anti-Leu M1, DM1, and Tü9--were examined in paraffin wax sections in Hodgkin's disease under a variety of different fixation and pre-treatment conditions, using four immunochemical detection techniques. All three antibodies(More)
The incidence and significance of the expression of the antigen defined by the monoclonal antibody Ca 19.9 (Sialyl Lea) has been assessed in human breast tissue. Frozen and formalin-fixed, paraffin embedded specimens of normal, hyperplastic, pregnant breast and carcinomas were examined using an immunoperoxidase technique. Ductal and acinar epithelium of(More)
Monoclonal antibodies directed against O(H) blood group antigen and 3-fucosyl-N-acetyllactosamine have been used to investigate the incidence and significance of these type 2 blood group chains in non-malignant and malignant human breast tissue. The findings have been compared with those obtained with the fucose-binding lectins, Ulex europeus I and Lotus(More)
The potential of 1,3-dichloropropene (1,3-DCP) to induce dominant lethal mutations in the germ cells of male CD rats following inhalation exposure was investigated. Groups of 11-week-old males (30 animals/group) were exposed to 1,3-DCP vapors by inhalation at targeted concentrations of 0 (negative control), 10, 60, and 150 ppm for 10 weeks (6 hr/day, 7(More)
