Figure 6From: In vitro modulation of inflammatory cytokine and IgG levels by extracts of Perna canaliculus Dose response effects of Perna (Tween-20 extract) on IL-1 secretion levels in U-937 cell line. Each bar represents the mean ± SEM of data points from three independent experiments with triplicate wells. Columns representing the different concentrations are statistically different from the stimulated but untreated baseline controls (no Perna). P ≤ 0.01.Back to article page
