Cytotoxicity of a new hemostatic agent on human pulp fibroblasts in vitro.

OBJECTIVE

The objective of this study was to evaluate the cytotoxicity of the plant extract ankaferd blood stopper (ABS) in vitro.

STUDY DESIGN

ABS was eluted with fresh Dulbecco's Modified Eagle's Medium (DMEM) without serum for 72 h, at 37 °C. The cells treated with various dilutions of ABS were seeded into 96-well microplate at 10⁴/well in triplicates. Cells without treatment served as a control group. The number of viable cells after 48 h incubation was determined by a modified 3-(4, 5-dimethyl-thiazol-2-yl)-2, 5-diphenyl-tetrazolium bromide (MTT) assay. The relative viability of pulp cells was expressed as color intensity of the number in the experimental wells relative to that of the control group. Absorbances were read at 570 nm on a microplate reader with a background subtraction at 620 nm.

RESULT

The results showed that ABS was cytotoxic to human pulp fibroblasts by MTT assay.

CONCLUSIONS

The influence of cytotoxicity to human pulp fibroblasts depended on concentration of ABS. The more dilutions exhibited less cytotoxic characteristics compared to the more concentrated forms.
