Figure 1.

Left: stimulation by bell pepper-PS and carrot-PS of in vitro phagocytosis of fluorescently labelled E. coli by phagocytic cells from human blood. Right: stimulation by hoodia PS extracts (and 50 ng/mL LPS as control) before and after passage over C18 column. +Macer indicates effect of hoodia-PS after 24 h incubation with Macer-8W enzyme mix. Results are expressed as % of stimulation by positive control (average + SEM of three donors). LPS +C18 column is significantly different from LPS, and 3 µg/mL hoodia PS + Macer from the same concentration without Macer, (** p < 0.01).
