Available in PDF, EPUB and Kindle. Book excerpt: Atlas of Histology of the Juvenile Rat should be of interest to toxicologic pathologists, toxicologists, and other biological scientists who are interested in the histomorphology of juvenile rats. For several decades the laboratory rat has been used extensively in nonclinical toxicology studies designed to detect potential human toxicity of drugs, agrochemicals, industrial chemicals, and environmental hazards. These studies traditionally have involved young adult rats that are 8-10 weeks of age as studies are started. It is becoming increasingly apparent that children and young animals may have different responses to drug/chemical exposures, therefore, regulatory agencies are emphasizing toxicology studies in juvenile animals. While the histologic features of organs from young adult and aged laboratory rats are well known, less is known about the histologic features of organs from juvenile rats. Final histologic maturity of many organs is achieved postnatally, thus immature histologic features must be distinguished from chemical- or drug-related effects. While this postnatal organ development is known to exist as a general concept, detailed information regarding postnatal histologic development is not readily available. The Atlas includes organs that are typically sampled in nonclinical toxicology studies and presents the histologic features at weekly intervals, starting at birth and extending through postnatal day 42. - Written and edited by highly experienced, board-certified toxicologic pathologists - Includes more than 700 high-resolution microscopic images from organs that are typically examined in safety assessment toxicology studies - Detailed figure legends and chapter narratives present the salient features of each organ at each time interval - Figures are available for further study via Elsevier's Virtual Microscope, which allows viewing of microscopic images at higher magnification - Valuable resource for toxicologic pathologists who are confronted with interpretation of lesions in juvenile rats in situations where age-matched concurrent controls are not available for comparison, e.g., with unscheduled decedents - Figures are available for further study on ScienceDirect with Virtual Microscope, which allows viewing of microscopic images at higher magnification

Download or read book Hazard Assessment of Chemicals written by Jitendra Saxena and published by Elsevier. This book was released on 2013-10-22 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hazard Assessment of Chemicals: Current Developments, Volume 2 contains authoritative articles, which provide a comprehensive review and evaluation of important information on chemical spills, and presents case studies that show the applications of methods and approaches to environmental and health hazard assessment of chemicals. The book is comprised of five subject reviews and two case studies of chemical spills. Experts tackle subjects on the use of simulation models to determine pollutant behavior and pollutant migration; use of microcosms to assess chemical effects on the properties of aquatic ecosystems; and metabolism and disposition of potentially hazardous chemicals in maternal-embryonic/fetal systems. Epidemiological approaches to chemical hazard assessment and a review of The National Toxicology Program (NTP) in the Department of Health and Human Services are also presented. Environmentalists, ecologists, toxicologists, public safety officers and workers, and those concerned with the health effects of chemical agents in the environment will find this text invaluable.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ionic liquids (ILs) are synthetic solvents with applications in a variety of industrial and chemical industries. Human exposure to this diverse chemical class is primarily through dermal or oral routes. Research suggests toxicity may be associated with IL structural characteristics, including the type of cation base or alkyl chain substitutions associated with the cation. To further investigate this hypothesis, the National Toxicology Program (NTP) conducted 3-month toxicity studies in male and female Sprague Dawley (Hsd:Sprague Dawley(r) SD(r)) rats and B6C3F1/N mice (n\s=\s10/sex/exposure group; 3\sexposure concentrations per IL) to compare the relative toxicities of four ILs administered via drinking water--1-ethyl-3-methylimidazolium chloride (Emim-Cl),1-butyl-3-methylimidazolium chloride (Bmim-Cl), 1-butyl-1-methylpyrrolidinium chloride (Bmpy-Cl), and n-butylpyridinium chloride (NBuPy-Cl). To select exposure concentrations for the 3-month studies, 2-week drinking water studies in rats and mice were conducted to assess palatability and toxicity of each IL. Informed by the literature and preliminary palatability studies, exposure concentrations in the 2-week studies ranged from 0\sto 100\smg/mL. Clinical observations (e.g., thinness and ruffled fur), lower water consumption, and lower mean body weights were associated with higher IL exposure concentrations. At the end of the 2-week exposure period, a range of organ weight changes and histological lesions was observed in rats and mice exposed to ILs. These observations were considered secondary to body weight changes and/or stress, rather than a direct toxic effect from 2-week IL exposure. Exposure concentrations (ranging from 0\sto 30\smg/mL) were selected for the 3-month studies because of the observed relative decreases in mean body weight (≤10%) and water consumption (

Hooth and published by DIANE Publishing. This book was released on 2009-02 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chromium is a metal that exists in a variety of valence states, depending on surrounding conditions and what other atoms it is bound to. The most stable forms are metallic chromium, trivalent chromium (chromium III), and hexavalent chromium (chromium VI). Chromium VI has been shown to cause cancer when inhaled in the air. Because compounds containing chromium VI occur as contaminants in drinking water, scientists studied the effects of sodium dichromate dihydrate (SDD) in drinking water on rats and mice to identify potential toxic or cancer-related hazards. Results showed that rats exposed to SDD had carcinomas of the mouth, but none occurred in the control rats. Mice receiving SDD had greatly increased rates of cancer of the small intestine. Illus.
