This work addresses nasal dosimetry and toxicity of Inhaled Xenobiotics.; Originally Published As A Special Issue Of The journal "Inhalation Toxicology", the contributions are derived from a Chemical Industry Institute of Toxicology CIIT symposium held in September in Durham, North Carolina.

A xenobiotic is a chemical substance found within an organism that is not naturally produced or expected to be present within the organism. It can also cover substances that are present in much higher concentrations than are usual. Natural compounds can also become xenobiotics if they are taken up by another organism, such as the uptake of natural human hormones by fish found downstream of.

respectively) due to their more erect stature. The degree of this bend in the upper airway impacts the regional dosimetry of some inhaled agents. The presence of exudate in the nasal cavity is a valuable indication of nasal toxicity. Three-dimensional, anatomically accurate computational fluid dynamics (CFD) models of the rat, monkey, and human nasal passages have been developed to predict inhaled airflow patterns and formaldehyde uptake to elucidate the roles of nasal anatomy and airflow on formaldehyde toxicity (Kepler et al., ; Kimbell et al.,a,b Cited by: To better understand and predict gender differences in response of the nasal epithelium to inhaled xenobiotics, gene expression profiles from naive male and female Sprague-Dawley rats were.

The conceptual basis for the dosimetry adjustments applied to inhaled agents and other considerations specific to this administration route are addressed in Chapter 3. The aim of the inhalation reference concentration (RfC) methodology is to establish a relationship between a particular agent in the air and a specific health effect (or effects).

This review examines issues related to the toxicological testing of pharmaceuticals delivered by the inhalation or nasal route. The purpose of the toxicology studies is to conduct studies in animals that will aid the assessment of the safety of these agents delivered to patients.

Inhaled toxicants that do not exert immediate toxic effects can pass through the lung, reach the capillaries, and be transported by the blood to other tissues where they can cause injury. xenobiotic: [ ze″no-bi-ot´ik ] a chemical compound foreign to a given biological system.

With respect to animals and humans, xenobiotics include drugs, drug metabolites, and environmental compounds such as pollutants that are not produced by the body. In the environment, xenobiotics include synthetic pesticides, herbicides, and industrial.
