Figure 2From: Effects of PM10 in human peripheral blood monocytes and J774 macrophagesThe intracellular calcium concentration (nM) in human monocytes on treatment with PM10 at a concentration of 10 μg/ml. Particles and calcium antagonists were added at zero time and the experiment run for 800 seconds in total (first 800 seconds shown). There was a significant difference between PM10-treated cells and PM10 and calcium antagonist treatment at each time point tested (p < 0.05). Data represents the mean ± SEM of the ratio of 340/380 nm. (n = 3).Back to article page
