...) by animals, few studies on the metabolism of these xenobiotics by plants has been reported. This study was designed to determine whether a plant cell culture derived from alligator weed ( Alternanthera philoxeroides ) activates or detoxifies these PAH to more or less active mutagenic compounds. The mutagenic...

..., (2) ease of determination at concentrations present in indoor air, and (3) relationship to other components of environmental tobacco smoke. 3-ethenylpyridine continine deposition environmental tobacco smoke exposure isoprene mutagen nicotine respirable suspended particles (RSP...

... Barley ( Hordeum vulgare L.) and Australian saltbush ( Atriplex semibaccata )plants and deoxyribonucleic acid (DNA) isolated from barley were exposed to the known carcinogen/mutagen, N-methyl-N-nitrosourea (MNU). DNA was isolated, digested to a mixture of deoxyribonucleoside 5'-monophosphates...

.... Well prepared slides were photographed under 400X magnification and analyzed for SCE frequencies. In addition, the spontaneous SCE frequency of Tradescantia was compared with those of Vicia and Allium . Tradescantia bioassay sister-chromatid exchange mutagen Yan Peng t and Te-Hsiu Ma...

... This paper provides general and specific guidance for the development and implementation of a quality assurance program for Ames testing. An effective quality assurance program is needed to assure that data produced from short-term mutagenicity testing (e.g., the Ames test) are of known quality...

... Genetic toxicology is an area of scientific research which is receiving increasing attention. The increasing number of regulations regarding environmental mutagens and carcinogens has stimulated the development of numerous short-term screening test systems capable of detecting these substances...
