Preliminary study on immunosuppressive effects evaluation of biomaterial / 中国医疗器械杂志

ABSTRACT

In this paper, an immunosuppression model of immunotoxicity built through applying immunosuppressive agent-cyclophosphamide. Subsequently the changes of some assessment indexes including total amount of lymphocytes and concentration of cytokine TNF-alpha in peripheral blood were observed and were used to evaluate immunotoxicity induced by Medical Heat Vulcanizing Silicone Rubber. The final results showed no immunosuppressive effect caused by this material. The study provide effective and sensitive detection technique for evaluation of medical devices and biomaterials' immunotoxicity.
