Abstract
Total synaptonemal complexes of male mouse meiotic chromosomes were examined under electron microscope at different periods after a single injection of the antitumor drug camptotecin. At the stage of meiosis prophase I, the drug induced sharp decondensation of chromatin, distention of chromosomes and elements of synaptonemal complex, and blocked desynapsis of homologous chromosomes at the diplotene stage, thus “arresting” damaged cells. The effect of camptotecin lasted 34 days after injection and involved 15 to 90% cells in different periods.
