title: Examination of naturally occurring polyacetylenes and alpha-terthienyl for their ability to induce cytogenetic damage.
abstract: alpha-Terthienyl and 5 polyacetylenes were examined for chromosome damaging activity using Syrian hamster cells. None of these naturally occurring compounds induced sister chromatid exchanges and neither alpha-terthienyl nor phenylheptatriyne induced chromosome aberrations.
