Cytokinesis-block micronucleus assay (CB-MNA) was applied for comparison of radiation sensitivity of 25 human malignant melanomas in primary culture. Cells obtained from tumor specimens were irradiated (0-4.Gy) on dishes, incubated with cytochalasin B (2 micrograms/ml) to block cytokinesis, stained in situ and micronuclei (MN) scored in binucleate cells(More)
A potential usefulness of micronucleus assay for prediction of tumour radiosensitivity has been tested in 64 patients with advanced stage (II B-IV B) cervical carcinoma treated by radiotherapy. The study of cellular radiosensitivity in vitro was conducted in parallel with the study of cellular damage after tumour irradiation in vivo. Radiosensitivity of in(More)
The multicellular megacolonies of human melanoma Me45 line growing on one part of the bottom of culture flasks were irradiated with 5 Gy (60Co), whereas megacolonies growing on the second part of the bottom were shielded. The bystander effect of radiation-traversed cells on non-traversed cells was studied during postradiation co-cultivation. Activity of(More)
