To evaluate the ability of a tiered quantitative morphological approach to reveal developmental neurotoxicity, morphometric parameters were measured in the offspring of rats treated with methylazoxymethanol (MAM) during days 13-15 of pregnancy. Treatment was aimed at inhibiting the proliferation phase of hippocampal neurons while leaving cerebellar neurons(More)
Polyunsaturated fatty acids, including docosahexaenoic acid (DHA), are natural constituents of the human diet. DHA-algal oil is produced through the use of the marine protist, Ulkenia sp. The reproductive toxicity of DHA-algal oil was assessed in a one-generation study. Rats were provided diets containing DHA-algal oil at concentrations of 1.5, 3.0, or(More)
Current developmental and reproductive toxicity protocols include only a limited set of parameters for effects on the developing immune system. In this study, a wide range of immunological parameters were included in a pre- and postnatal developmental toxicity study. Dose-response data were compared to determine the relative sensitivity of different immune(More)
Developmental immunotoxicity assessment is considered ready for inclusion in developmental toxicity studies. Further evaluation of proposed and additional assays is needed to determine their utility in assessing developmental immunotoxicity. In this study, a wide range of immunological parameters was included in an extended one-generation reproductive(More)
To determine relevant endpoints for evaluating developmental immunotoxicity due to juvenile exposure and optimal age of the animals at assessment, a wide range of immunological parameters were assessed in a juvenile toxicity study. Rats were exposed to di-n-octyltin dichloride (DOTC) by gavage from postnatal day (PND) 10 through PND 21 and via the diet(More)
Exposure of males to some genotoxic chemicals causes DNA damage in spermatozoa resulting in embryotoxicity and developmental defects in their offspring. This study demonstrates that cisplatin-DNA adducts could be measured in spermatozoa following treatment with the antineoplastic drug, cisplatin. The formation of spermatozoa cisplatin-DNA adducts showed(More)
Our aim was to investigate a model of the morphologic approach proposed in guidelines for developmental neurotoxicity testing (DNT). Hereto, a limited DNT study [EPA Health Effects Test Guidelines OPPTS 870.6300, 1996a. Developmental Neurotoxicity Study "Public Draft", United States Environmental Protection Agency; Prevention, Pesticides and Toxic(More)
The susceptibility of developing immune system to chemical disruption warrants the assessment of immune parameters in reproductive and developmental testing protocols. In this study, a wide range of immune endpoints was included in an extended one-generation reproduction toxicity study (EOGRTS) design to determine the relative sensitivity of immune and(More)
One-generation reproductive toxicity studies have been conducted on the following three oximes: acetaldehyde oxime (AAO), aldecarb oxime (ADO), and methyl isobutyl ketoxime (MIBKO). The studies followed the OECD 415 guideline (One-Generation Reproduction Toxicity Study), with a few modifications. Rats were exposed to the test material for 10 weeks prior to(More)
