Cisplatin (CDDP), homoharringtonine (HHT), mitoxantrone (MIT) and hydroxycamptothecin (HCPT) are highly effective anti-tumor drugs. To evaluate their effects in the therapy of leukemia and establish a valuable method to estimate anti-tumor drugs, Annexin V/PI double parameter flow cytometry was used to detect the effects of these drug inducing apoptosis and death in Jurkat cell line. The results showed that MIT and HCTP-induced apoptosis effects on Jurkat cell line were obvious at 4 hours in early phase after adding drug (P < 0.05) and at 8 hours in late phase after adding drug (P < 0.05). HHT had obvious effect on inducing apoptosis of Jurkat cells, but no significant difference from low to high doses. The effect of CDDP on inducing apoptosis of Jurkat cell line was obviously weaker than that of HHT, MIT and HCPT, its weak effect on apoptosis of Jurkat cell line was found only at high concentration of drug for long time. Death effects on Jurkat cell line can not be observed in every experimental group. It is concluded that low dose of MIT can effectively induced apoptosis of Jurkat cell line. Annexin V/PI double parameter flow cytometry can be used as a reliable method for clinical screening anti-tumor drugs.
