[Detection of human proteins in the epoxy housing of implanted cardiac pacemakers (author's transl)].
On cardiac pacemakers with epoxy resin encapsulation of a certain type which had been implanted in humans for a considerable time, sessile human proteins were detected in the epoxy by means of immunofluorescence microscopy. These proteins are not extractable from shavings of the epoxy casing using the method described, as was shown by two different methods. The results of LOWRY's test on the eluate are invalid, because we assume that extractable amino groups are responsible for the positive results.
