Various biometerials have been researched and have been developed for treatment of some disease through transplantation to body. They have been evaluated by in vitro cytotoxicity test using some skin-derived cell lines for prediction of their biocompatibility in vivo. However, the results of experiments using mesenchymal or epithelial cells could not be considered in vivo immune reaction. In this study, we evaluated the biomaterial-elution (elute from high density polyethylene film) using some cell lines (L929, Jurkat, U937) in vitro, and then that results were compared with in vivo results from guinea pig sensitization test. In sensitization test, saline and elution of syringe could not induce erythema, but only DNCB (hypersensitive chemical) induce erythema at guinea pig sensitization test. In cell experiment, the cytotoxicity results of inflammatory cells (Jurkat; T lymphocyte, U937; monocyte) was no difference with L929 (fibroblast) in the overall trend. However, inflammatory cell lines were only secreted inflammatory cytokine (TNF-
