Abstract

Foam sponge fragments were implanted into the retro­ stcrnal cavity of dogs. Extractions were perforrned from the seventh to twenty-seventh week after the implantations, and this explanted material was processed for optical and electronmicroscopical studies. Histochemistry to detect elastic fibres was al'so performed. The char­acteristic cells from an aseptic, chronic inflammation have been obser­ved, as welI as severa] degrees of fibrosis that varied directly with the implantation time. Probable fibrc-producing cells were detected. Imper­meability of the tube after 25 weeks of implantation and its use for sustiluting hollow organs as wel´ as the presence of the different kinds of cells there encountered havc been discussed.
