Figure 7From: Heavy metal exposure reverses genetic resistance to Chlamydia-induced arthritisSerum nitric oxide and VEGF profiles. Serum nitric oxide (NO) levels (a) and vascular endothelial growth factor (VEGF) levels (b) with the local exposure to Chlamydia trachomatis (Ct) or a systemic exposure to HgCl2 (Hg) or both (Ct + Hg) in contrast to normal rat serum. For both NO and VEGF, the increment seen with dual-exposure to Ct and HgCl2 was statistically greater than that seen with either Ct or HgCl2 alone (n = 4 in each group). HgCl2, mercuric chloride.Back to article page
