Pharmacokinetics of vinylidene chloride.
Dear Sir: The recent article by McKenna et al. (1) on phar-macokinetics of vinylidine chloride (VDC) in the rat has evoked a number of thoughts. These relate both to one detail of data presentation from the excellent experimental studies and to the general role of pharmacokinetics in supporting risk assessment from high dose studies in mammals. The detail concerns Figure la (Figure 2 of the McK...
متن کاملCarcinogenicity studies on vinylidene chloride.
Results of a study on Wistar rats regarding a possible carcinogenic effect of vinylidene chloride (VDC) were presented previously by one of the authors. Due to the unclear character of these results, a second inhalation study was initiated with Sprague-Dawley rats. Groups of 60 animals were exposed to 100 and 75 ppm VDC, along with one control group. A final report on the pathological results m...
متن کاملInhalation toxicity of vinyl chloride and Vinylidene chloride*
Exposure of mice to 1000 ppm of vinyl chloride (VC), 6 hr/day, 5 days/week, caused some acute deaths with toxic hepatitis and marked tubular necrosis of the renal cortex. Starting the sixth month, mice exposed to 1000, 250, or 50 ppm of VC became lethargic, lost weight quickly, and died. Only a few mice exposed to 50 ppm survived for 12 months. Pulmonary macrophage count was elevated in some mi...
متن کاملPharmacokinetics of vinylidene chloride in the rat.
The metabolism of inhaled vinylidene chloride in rats represents a balance of biotransformation pathways leading to the formation of a reactive alkylating species which is normally detoxified by conjugation with glutathione. Detoxification of the reactive intermediate formed from inhaled VDC is dependent upon the availability of hepatic glutathione (GSH); as VDC exposure concentrations are incr...
متن کاملUniversal Ferroelectric Switching Dynamics of Vinylidene Fluoride-trifluoroethylene Copolymer Films
In this work, switching dynamics of poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] copolymer films are investigated over unprecedentedly wide ranges of temperature and electric field. Remarkably, domain switching of copolymer films obeys well the classical domain nucleation and growth model although the origin of ferroelectricity in organic ferroelectric materials inherently differs ...
