[Study of growth inhibitory effect and apoptosis induced by different matches of Tanshinone IIA and Salvianolic Acid B on Acute Promyelocytic Leukemia cells (HL-60)].

Objective: To investigate the growth inhibiting and apoptosis inducing mechanisms of different matches of Tanshinone IIA and Salvianolic Acid B on Acute Promyelocytic Leukemia Cells (HL-60).

Methods: The HL-60s' growth inhibition and apoptosis-induced rates were detected by MTT reduction assay and flow cytometry with various matches of TanIIA and SalB.

Results: The HL-60s' growth inhibition and apoptosis-induced rates were found higher in the group of TanIIA plus SalB than other single groups, and in the group TanIIA-SalB (10-5 microg/ml) they were the highest (P<0.
