Reduced amount of malonil dialdeide (MDA) by lipid peroxydation in presence of a lucegenin probe and the xanthine/xanthine oxydase system with 150 µg of different plant extracts.

<p><i>Ctr: Control, ***p<0.001, **p<0.01, *P<0.05.</i></p

Protective effect of 12 µg plant extracts from Fe²⁺ and H₂O₂ induced <i>E. coli</i> plasmid damage.

<p><i>Ctr: control.</i></p

Distributions of: a) comet tail moment (TM); b) tail length (TL); c) tail intensity (TI) in white blood cells from healthy human donors treated with hydrogen peroxide and 100 µg of plant extracts.

<p>Data (at least 150 scores/sample) are mean values +/− SEM. <i>p</i><0.05 is considered significant.</p

Plant extracts modulate γδ T cell cytokine production and proliferation.

<p>Purified-<i>γδ</i> T cells were incubated with IPP and IL-2 in the presence of different concentrations of plant extracts induced TNF-α production (A) and on γδ T cell proliferation (B) were assessed by Flow Cytometry. Values of <i>p</i><0.05 were considered statistically significant. <i>CTR: Control; TNF-a: Tumor necrosis Factor-alpha; IPP: isopentenyl pyrophosphate.</i></p

Plant extracts modulate LPS –induced TNF-α production by imDC.

<p>imDC were generated from monocytes positively separated from PMBC by anti-CD14 magnetic beads and cultured for 5 days in the presence of GM-CSF and IL-4. Different concentrations of plant extracts were added to imDC in the presence of LPS and TNF-α production was assessed by Flow Cytometry. Values of <i>p</i><0.05 were considered statistically significant. <i>CTR: Control; imDC: immature Dendritic Cells; LPS: Lipopolysaccharide; TNF-α: Tumor necrosis factor alpha.</i></p

Evaluation of the chemiluminescence (CL) signal inhibition in presence of different concentrations of plant extracts versus: A) Hydrogen peroxide (H₂O₂) B) Anion superoxide (O₂) generated by Xanthine – Xanthine oxidase system.
