A series of metal chlorides were subjected to the wing spot test of Drosophila melanogaster. In the test, larvae trans-heterozygous for the wing-hair mutations mwh and flr were orally treated at the third instar stage with a test compound and the win

Employing a suspension culture of FM3A cells, we examined the cytotoxic and mutagenic effects of various chemical compounds. Mutagenicity of various types of mutagens (MNNG, ENNG, sterigmatocystin, mitomycin C, Trp-P-1, and X-rays) was sensitively de

Mutagenic activities of 4-aminopyridine (4AP), 4-aminoquinoline (4AQ), 9-aminoacridine (9AA) and harman (HM) were examined by the Salmonella test system in the presence of cobalt(II) chloride (CoCl2), which itself is non-mutagenic in this system. Mut
