individuals handling antineoplastic drugs or their wastes may absorb these potent genotoxic agents. the effects of handling antineoplastic drugs were examined in a group of 24 nurses working in the hematology and oncology departments of two different university hospitals in shiraz (iran) and in a group of 18 unexposed nurses as control group. the cytogenetic repercussions of exposure were asses...

chromosomal appearance of 12 holstein bulls selected for artificial inseminations were examined bysister chromatid exchanges (sces). for differential staining of sister chromatids bromodeoxyuridine (brdu)was inoculated in lymphocyte cultures. the mean, maximum and minimum number of sce per cell weredetermined 6.8 ± 1.14, 8.3 ± 1.1 and 5.7 ± 1.5, respectively. sce frequencies of all animals were...

Cytotoxic effects of treating RIF-1, EMT6, and 9L tumor cell lines with c/s-diamminedichloroplatinum(ll) were measured with the sister chromatid exchange assay and compared to results obtained with the colony-forming efficiency assay. The greatest number of sister chromatid exchanges was induced in RIF-1 cells, fewer in EMT6 cells, and the least in 9L cells. Cell survival data obtained with the...

An automatic system for detecting and counting sister chromatid exchanges in human chromosomes has been developed. Metaphase chromosomes from lymphocytes which had incorporated 5-bromodeoxyuridine for two replication cycles were treated with the dye 33258 Hoechst and photodegraded so that the sister chromatids exhibited differential Giemsa staining. A computer-controlled television-microscope s...

Sister chromatid exchange (SCE) techniques have been shown to have great potential for use in the in vitro screening of suspected mutagens and carcinogens. Application of these techniques to bone marrow cells and/or lymphocytes from patients with various hematologic malignancies has demonstrated significant abnormalities in SCE frequencies in some of these diseases, as well as showing drug trea...

The rate of sister chromatid exchange induced by several anti-herpes agents was measured to assess their potential mutagenicity. The agents--5-iodo-deoxyuridine (IDU), 5-trifluoromethyl-deoxyuridine (TFT), and [E]-5-(2-bromovinyl)-deoxyuridine (BVDU)--were incubated at various concentrations with human lymphocytes and fibroblasts, and that rate of sister chromatid exchanges was measured. In lym...
