O efeito de duas concentrações de cafeína (1500 e 2500 mg/ml) sobre o índice mitótico em Drosophila prosaltans foi analisado em células de gânglios cerebrais de larvas. Embora as diferenças detectadas entre células controle e tratadas não sejam significativas, as porcentagens obtidas poderiam ser sugestivas de algum efeito da cafeína ampliando a duração do processo de divisão celularThe 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 divisio
