[Biocompatibility of various surgical drainage materials in the cytotoxicity and implantation test].

The biocompatibility of 10 materials used for surgical drainage was evaluated in a cytotoxicity test and in rat subcutaneous tissue implantation test. All rubber materials and silikolatex were found to be cytotoxic. There was no correspondence of the results of the cytotoxicity test with those of the implantation test. Therefore various procedures for biocompatibility-testing should be used.
