Quaternary Ammonium Compound Toxicity in Chickens
Avian Diseases, 1982Two commercial White Leghorn flocks of 41,000 and 57,000 25-week-old hens experienced death losses of 676 and 1,089 birds in a week. Six birds from each flock were presented for necropsy to the Animal Disease Diagnostic Laboratory at Purdue University with a clinical history of excessive deaths, unsatisfactory production, and dehydration. Gross lesions

The main cause of failure of biomedical implants is bacterial infections. Despite all efforts, it will never be possible to completely free operating theaters from bacteria, as human bodies contain already 1014 bacteria. Once on a surface, bacteria start proliferating, while protecting themselves with a slime layer against the immune system and ...

Ototoxic Effect of Quaternary Ammonium Compounds
Acta Oto-Laryngologica, 1982In earlier investigations by the author it has been shown that chlorhexidine, when introduced into the middle ear of guinea pigs, caused serious damage to the inner ear. The present investigation was performed in order to study if the quaternary ammonium compounds benzethonium chloride and benzalkonium chloride, frequently used for skin disinfection ...

Two potential energetic compounds: Ammonium superoxide and ammonium ozonide
Journal of Energetic Materials, 2000Abstract Two proposed ionic compounds, NH4O2 and NH4O3, are discussed in terms of several properties related to energetic performance. These include oxygen content, moles of gas produced and heat released upon decomposition, and specific impulse. The heat release was calculated in each instance using the predicted lattice energy, which was obtained ...

Quaternary Ammonium Compounds as Preservatives*
Journal of the American Pharmaceutical Association (Scientific ed.), 1947The antiseptics employed were cetyl pyridinium chloride (Ceepryn) and p‐tertiary octylphenoxyethoxyethyl dimethyl benzyl ammonium chloride (Phemerol). Very low concentrations of these antiseptics were found effective in preserving both gelatin and sucrose solutions.
