Figure 1.
Changes in serum levels of acute-phase proteins and cytokines in rats injected with turpentine oil at 0.05, 0.2 or 0.4 mL/rat. (a) α 2-macroglobulin (α2M), (b) α 1-acid glycoprotein (AAG), (c) interleukin-6 (IL-6) and (d) cytokine-induced neutrophil chemoattractant-1 (CINC-1). Data are expressed as means ± SD (n = 6). *P < 0.05, significantly different versus 0.2 or 0.4 mL/rat injection group, as analysed by Student's t-test. **P < 0.05, significantly different versus 0.4 mL/rat injection group, as analysed by Student's t-test
