Abstract

Abstract: Objective To study the cytotoxicity of cervical collar in rehabilitation technical aids and to investigate the cytotoxicity of domestic marketed products.Methods According to the experimental principle of GB/T 16886.5-2003 and GB/T 16175-2008, microscopic observation and Thiazole Blue Colorimetric methods were used to observe the toxicity of extract from four different cervical collars on the cells (L929).Results When the concentration of the extract was 0.1 g/ml, the cytotoxicity was grade three and grade two in the cervical collars D and A, respectively; and it was grade one both in cervical collars B and C. When the concentration of the extract was 0.2 g/ml, the cytotoxicity was grade four in cervical collars A and D, and was grade two in cervical collars B and C.Conclusion The cervical collars varied in the cytotoxicity, especially in cervical collars A and D.

Key words: aids, cervical collar, cytotoxicity, Thiazole Blue Colorimetry
