  1. *Significantly different from corresponding sham; Between exposed groups of the same mouse strain; ‡Between mouse strains of the same exposure group (p < 0.05)
  2. §LDH and albumin data are represented as % corresponding sham.
  3. ||Percentage from a differential cell count of > 300 cells with the corresponding sham % in parentheses. Note. Data are means ± SE. Statistical comparisons were MMA-SS and S-Cr or GMA-MS and GMA-SS. Abbreviations are GMA-MS-gas metal arc-mild steel, GMA-SS-gas metal arc stainless steel, or MMA-SS-manual metal arc stainless steel welding fume; S-Cr-soluble chromium VI; LDH-lactate dehydrogenase; PMN-polymorphonuclear leukocytes
