Structural and ultrastructural investigations on the in vitro effects of plant extracts in chicken and rabbit whole blood cultures

Recently published data underline the beneficial effects of plant extracts, in correlation with those of associated classical treatments, when immune intervention is required. Such information strongly support researches on the possible immune-modulating activities of vegetal extracts with an increased bioavailability, pronounced therapeutic activity and lacking side effects, when compared to synthetic drugs. Still, the interactions between the plant extractions and the immune mechanisms are far from being solved. Thus, after the initial investigations on anti-tumor and anti-microbial effects, the researches switched to characterize the influence of plant extracts on different components of the immune system.
