The ordination techniques principal component analysis (PCA) and redundancy analysis (RDA) are considered to be useful tools for evaluating community responses in experimental ecotoxicology. Concepts and interpretation of these techniques are summarized. Application of PCA and RDA is illustrated in

Prior administration of valine to rats has been shown previously to prevent restraint stress-induced increases in brain tryptophan and 5HT turnover. The present study demonstrates that the accompanying attenuation of the corticosteroid response to this stress is substantially reversed by administrat
Toxic doses of tetracycline were injected intravenously in adult female rats to study the morphologic and cytochemical alterations produced in the liver. Fifty percent of the animals treated died within 48 hours; those surviving were sacrificed at 3, 7, 10 or 14 days later. Histologic sections of th
