Abstract

Arsenic is a grade I human carcinogen that can cause kinds of damage to the body. The heart is one of the main target organs of arsenic damage, but the preventive and curative measures underlying arsenic poisoning are not clear. To investigate the effect of tanshinone IIA sulfonate (STS) on the injury of H9C2 cardiomyocytes induced by NaAsO2,H9C2 cardiomyocyteswere divided into four groups where control group with general medium, arsenic (As) group received sodium arsenite (NaAsO2)-containing general medium, STS pretreatment+As group and finally the STS alone group. Compared with the control group, different concentrations of STS had no significant effect on the cell viability (n = 6, P > 0.05); Compared with the control group, there was no significant change in the viability of cells treated with arsenic for 12 h after STS pretreatment for 6 h (n = 6, P > 0.05),the viability of cells treated with NaAsO2 alone was decreased(n = 6, P 0.05) As a result, Sodium tanshinone IIA sulfonate can attenuate the injury of H9C2 cardiomyocytes induced by sodium arsenite.
