ABSTRACT
The effect of two concentrations of caffeine (1500 µg/ml and 2500 µg/ml) on mitotic indices of Drosophila prosaltans was analyzed in larval brain cells. Although the differences detected between treated and control cells were not significant, the percentages obtained suggest a possible effect of caffeine in slowing the process of cell division.
Keywords: Caffeine; mitotic index; Drosophila prosaltans.
