[Investigations of cytotoxicity of Heliosit depending on its polymerizing in vitro].

In this paper the authors describe the changing in cell culture of epithelioid cells of a permanent HEp-2-line basing on the one component composite Heliosit. Following the experiences with farmer test the authors mean that contact and local toxicity are not so heavy but depending from the polymerization of the materials. Warning is the arretation of some phases in cell cyclus and the changing of epithelioid cells in fibroblastoid cells. May it is a cell transformation necessary to examine in special tests.
