Abstract
Polytef paste was injected endoscopically into the bladder submucosa of five dogs. Two were sacrificed after two weeks and the lungs and brain dissolved in sodium hypochlorite solution. The centrifuged deposit revealed particles optically and morphologically indistinguishable from polytetrafluoroethylene when examined by polarizing light microscopy. The remaining three dogs were entered into a long-term study and will be the subject of a separate report.
