Plant lignan 7-hydroxymatairesinol (7-HMR) is a novel precursor of the mammalian lignan enterolactone. A 13 week toxicity study at dietary levels of 0, 0.25, 1, and 4% (w/w) of potassium acetate complex of 7-HMR (HMRlignan) was conducted in the Wistar rat. These dietary levels resulted in an average daily intake of 160, 640, and 2600 mg...

This publication is the ninth in a series of safety evaluations performed by the Expert Panel of the Flavor and Extract Manufacturers Association (FEMA). In 1993, the Panel initiated a comprehensive program to re-evaluate the safety of more than 1700 GRAS flavoring substances under conditions of intended use. Elements that are fundamental to the...

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...

Toxicogenomics can facilitate the identification and characterization of toxicity, as illustrated in this review. Toxicogenomics, the application of the functional genomics technologies (transcriptomics, proteomics and metabolomics) in toxicology enables the study of adverse effects of xenobiotic substances in relation to structure and activity...

The toxicity of α-cyclodextrin (α-CD), a cyclic polymer of six α-1,4-linked glucopyranosyl units with potential applications as a food ingredient, more specifically a water-soluble dietary fiber, was examined in a 4-week range finding study and a 13-week oral toxicity study in rats. In the 4-week study, the test substance was administered to...

The oral toxicity of α-cyclodextrin (α-CD) was examined in a 13-week feeding study in which groups of Beagle dogs received α-CD in the diet at concentrations of 0 (control), 5, 10, or 20% (4dogs/sex/group). No treatment-related changes were noted in behavior or appearance of the dogs and no mortalities occurred. Diarrhea occurred in all α-CD...

The accuracy of extended histopathology to detect immunotoxic chemicals in female B6C3F1 mice was evaluated under the auspices of the National Toxicology Program (NTP). A workgroup was formed consisting of four pathologists who conducted extended histopathological evaluation of lymphoid tissues obtained from a subset of NTP toxicology studies,...

Natural flavour complexes (NFCs) are chemical mixtures obtained by applying physical separation methods to botanical sources. Many NFCs are derived from foods. In the present paper, a 12-step procedure for the safety evaluation of NFCs, 'the naturals paradigm', is discussed. This procedure, which is not intended to be viewed as a rigid check...

The subacute oral and inhalation toxicity of furfural vapour was studied in Fischer 344 rats to investigate whether route-to-route extrapolation could be employed to derive the limit value for inhalation exposure from oral toxicity data. Groups of 5 rats per sex were treated by gavage daily for 28 days at dose levels of 6-192 mg/kg bw/day, or...

Several cationic amphiphilic compounds are known to induce phospholipidosis, a condition primarily characterized by excessive accumulation of phospholipids in different cell types, giving the affected cells a finely foamy appearance. Excessive storage of lamellar membranous intralysosomal inclusion bodies is the hallmark for phospholipidosis on...
