Bunte salts have bacterial, insecticidal, and fungicidal properties, and are also used as chelating agents (qv) or surfactants (qv) (97,98). Bunte salts have been tested for preirradiation protection for mammals exposed to lethal radiation doses (99,100) (see Radioprotectiveagents). [Pg.32]

Radiation adversely affects limb regeneration of amphibians, alters DNA metabolism, and increases the frequency of chromosomal aberrations and liver lesions (Table 32.25). In some species of amphibians and reptiles, as in many mammals, mortality rates after acute exposure to radiation do not stabilize within 30 days — effectively invalidating the conventional LD50 (30-day postexposure) value. In the rough-skinned newt (Taricha granulosa), for example, the minimal LD50 dose at 200 days after irradiation was 2.5 Gy, compared with 350 Gy at 30 days (Willis and... [Pg.1713]

Following the first demonstration of the deleterious effect of radiation and ultimately that of chemicals on genetic material, numerous test systems have been used to study the induction of DNA damage, chromosomal aberrations, and mutations. This broad spectrum of activity resulted in the birth of genetic toxicology. The test organisms include prokaryotes (e.g., bacteria, fungi) and eukaryotes (e.g., yeast, fruit flies, plants, mammals). [Pg.305]
