Nitric oxide (NO) production. (a) Wild-type (129 WT mice) and (b) 5-LO-/- mice infected with trypomastigote forms of T. cruzi Y strain and treated or untreated with NOS inhibitors. NO was determined by measuring the nitrite levels in plasma employing the cadmium-copper system followed by the Griess reaction. animals in each group and values are the for three independent experiments. . #, ns: not significant, compared with uninfected group or between groups.
