Long term CS exposure induced the up-regulation of TNF-α (Figure 3,
panel A) and IL-8 (Figure 3, panel B) in BALF. Only PTX was able to
down-regulate the expression of TNF-α (P < 0.05), and
the addition of TRI did not improve this inhibitory. PTX, THEO and TRI
resulted in the down-regulation of IL-8 expression (P <
0.05), and the addition of TRI intensifies this inhibition (P< 0.05), not only when used with PTX and THEO but also when
used with ROF.
