摘要:: This study was aimed to investigate the cytotoxic effect of the Naja Naja Actra Venom Component (NNAVC) combined with activated immune cells on human acute myeloblastic leukemia line KG1a cells. The cytotoxic effects of NNAVC at different concentrations on KG1a cells were measured by CCK-8 method. LDH releasing assay was used to detect the cytotoxic effects of activated immune cells, NNAVC combined with activated immune cells on KG1a cells and the sensitivity of KG1a treated with NNAVC to activated immune cells. The results showed that the inhibitory rate of NNAVC on KG1a cells increased with the concentration enhancement, the cytotoxicity of activated immune cells at the different effector to target (E:T) ratios(6.25:1, 12.5:1, 25:1) on KG1a cells were 12.30%, 24.85% and 52.26%. The cytotoxicity of NNAVC combined with activated immune cells at the different E:T cell ratios (10:1, 20: 1) on KG1a cells were 56.21% and 85.59%, which were higher than that of NNAVC or activated immune cells alone. The cytotoxicity of activated immune cells at the E: T cell ratio of 10:1 on KG1a cells treated with NNAVC at different concentrations were 25.65%, 31.33%, 28.63% and 16.78%, respectively, and that at the E:T cell ratio of 20: 1 were 40.62%, 44.70%, 44.62% and 40.72%. It is concluded that:both of NNAVC and activated immune cells have lethal effect on KG1a cells, and the combination of NNAVC and activated immune cells can strengthen their effect on KG1a.
