Osmolarities and protein levels of in vivo inflammatory liquids. Acute inflammation in mice was induced either by BCG (A) (Bacille Calmette-Guérin, Mycobacterium bovis attenuated strain) or CFA (Complete Freund Adjuvant) footpad inflammation (B) as described in the Material and Methods section. Inflammatory liquids were withdrawn and osmolarity values measured A) (Saline [291.17–319.06]; BCG 0.01 mg [426.09–567.37]; BCG 0.1 mg [437.07–603.99]; BCG 1 mg [453.22–599.81]) and B) (Saline [282.98–303.08]; CFA [360.90–463.83]). C) Proteins from inflammatory liquids were migrated on a 4.5% PAGE gel and stained with silver nitrate. For each group, the horizontal bar is the median. Upper values represent the global p-values (Kruskal-Wallis test). The p-value given by the Tukey test above a stripchart indicates the result of the comparison of this group versus control. CI at 95% are given in parentheses (n = 6).
