Cl₂ exposure does not affect Mahma/NONOate (MNO)- or sodium nitroprusside (SNP)-induced vasodilation of aorta. Rats were exposed to air (open squares) or Cl₂ (400 ppm, 30 min). Aorta were isolated at 6 (closed triangles), 24 (closed circles), or 48 hours (open circles) thereafter, and vasodilation responses to the NO donors MNO (A) or SNP (B) were determined. Data show mean ± SEM. No significant differences were observed by two-way repeated measures ANOVA with Bonferroni post-test (n = 3–8).
