[Evaluation of gene protective effects of some natural anti-mutation substance]

Antimutation activity of some bee products was evaluated with a battery of test-systems. Tablets of apilac prepared out of queen bee milk did not demonstrate gene-protective effects in Ames' test. Other bee products, i.e. propolis, beebread, honey preparations 1 and 2 and queen bee milk were able to mitigate to a degree ill effects of some chemical and physical mutagenes. Propolis was found to be toxic to the yeast cell. Antimutation properties of natural queen bee milk revealed in the experiment with test-objects were lost after the product had been processed into the tabloid form or stored at room temperature.
