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 observa-tion and Thiazole Blue Colorimetric methods were used to observe the toxicity of extract from four different cer-vical 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 cervi-cal 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 cer-vical collars B and C. Conclusion The cervical collars varied in the cytotoxicity,especially in cervical collars A and D.
