The effect of OCC is dose-time dependent. By using the LKB2277 Bioactivity Monitor,we determined the heat production rate of HL-60 cells treated by OCC at different concentrations. It was found that the heat production rate of HL-60 cell treated by OCC gradually decreased to that of normal human neutrophiles.展开更多
