Figure 1From: Why does the hemolytic activity of silica predict its pro-inflammatory activity?Hemolytic activity of Qz-3 (pure quartz) and Qz-4 (pure quartz etched with HF). Qz-3 and Qz-4 were incubated at increasing concentrations expressed as surface area doses (cm2/ml) in the presence of human red blood cells. Values are mean ± SD from five independent experiments. *p < 0.05 and ***p < 0.001 vs control not exposed to silica particles.Back to article page
