[Evaluation of nephrotoxicity induced by total terpenoids from Alismatis Rhizoma on HK-2 cells in vitro and its induction of apoptosis].

To evaluate the nephrotoxicity of total terpenoids from Alismatis Rhizoma on human kidney proximal tubular cells (HK-2), explore the iraction in inducing apoptosis of HK-2 cells, and provide reference for the research of controversial nephrotoxicity of total terpenoids from Alismatis Rhizoma, HK-2 cells were used and cells viability was measured by MTT colorimetric method. An assessment of cells apoptosis was also conducted by using flow cytometry. Meanwhile western blot assay was used to detect the protein expressions of caspase-3, Bcl-2, Bcl-xl, Kim-1, clusterin and TFF-3.
