ITOYAMA, Mary Massumi; BICUDO, Hermione Elly Melara de Campos  and  CORDEIRO, José Antônio. Effects of caffeine on mitotic index in Drosophila prosaltans (Diptera). Braz. J. Genet. [online]. 1997, vol.20, n.4, pp.-. ISSN 0100-8455.

The effect of two concentrations of caffeine (1500 mg/ml and 2500 mg/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
