Figure 3From: Intensive insulin therapy does not alter the inflammatory response in patients undergoing coronary artery bypass grafting: a randomized controlled trial [ISRCTN95608630]Cytokine production is highly compartmentalized. Concentration of IL-6 (a) and IL-10 (b) in mediastinal fluid at different time points after admission to the intensive care unit. (c) The ratio of IL-6 to IL-10 in mediastinal fluid is expressed as arbitrary units. No significant differences are found between both treatment groups. IL-6 and IL-10 levels are significantly higher in the mediastinal fluid samples than in plasma samples, indicating local production. Points are median values.Back to article page
