FIG. 2.

Kinetics of NO release induced by PAF. TG-elicited peritoneal macrophages from C57BL/6, infected or not with L. (L.) amazonensis and treated with PAF (10⁻⁶ M) or its vehicle. Nitrite levels were measured in the supernatants from cultures at 8, 24, and 48 h. The data represent the mean ± the SEM of three experiments performed as described in legend to Fig. 1. ∗, P < 0.01 (comparing PAF-treated with vehicle treated group).
