In Vitro Evaluation of Colloidal Silver on Immune Function: Antilymphoproliferative Activity

Figure 5

Cellular proliferation of PBMC treated with colloidal silver and mitogens. PBMC (1 × 10⁶ cells/mL) were treated with (a) negative control, (b) control, (c) PHA (5 μg/mL), (d) Con A (5 μg/mL), (e) AgC (17.5 ng/mL), (f) AgC (17.5 ng/mL) + PHA (5 μg/mL), or (g) AgC (17.5 ng/mL) + Con A (5 μg/mL) and incubated for 72 h at 37°C and 5% CO₂ atmosphere. Cellular proliferation was analyzed by microscopy fluorescence. AgC, colloidal silver; PHA, phytohemagglutinin; and Con A, concanavalin A.
