Behavioral toxicology.
The new fields of behavioral toxicology and behavioral teratology investigate the outcome of specific toxic exposures in humans and animals on learning, memory, and behavioral characteristics. Three important classes of behavioral neurotoxicants are metals, solvents, and pesticides. The clearest data on the deleterious effects of prenatal exposure to toxicants comes from the study of two metals...
متن کاملBehavioral responses to plant toxins by two omnivorous lizard species.
An ability to detect plant toxins and thereby avoid eating chemically defended plants would be very beneficial for omnivorous and herbivorous lizards. We studied the ability of the omnivorous Podarcis lilfordi to detect compounds belonging to three classes of common plant toxins, as well as responses indicating aversion. Solutions of the alkaloid quinine, saponin, and the phenolic coumarin, as ...
متن کاملMode of action and toxicology of plant toxins and poisonous plants
Plants have evolved the strategy to produce bioactive natural products as a means of defence against herbivores and microbes. Some plants produce toxins that can severely damage or kill a herbivore. The molecular mode of action of neurotoxins, cytotoxins, metabolic poisons, mutagens and toxins that affect skin and mucosal tissues are summarised and discussed. Important poisonous plants of Europ...
متن کاملToxicology and seafood toxins: domoic acid.
Marine and terrestrial food sources are susceptible to contamination by various industrial chemicals and microbial pathogens. Both types of hazard are amenable to regulatory assessment using a single toxicology data base, along with some knowledge of contaminant levels and consumption figures for food. On the other hand, regulatory problems persist with acutely toxic naturally occurring phycoto...
متن کاملUse of activity measures in behavioral toxicology.
Locomotor activity measurements have been used extensively to evaluate chemically-induced changes in CNS function. This paper focuses on several factors including apparatus, age, biological rhythm, and social setting, which influence both locomotor activity levels per se and chemically induced changes in these activity levels. These data illustrate that failure to recognize, specify, and consid...
