Table 1 The expression of inducible and endothelial nitric oxide synthase (iNOS and eNOS) in lung tissue

From: Niacinamide mitigated the acute lung injury induced by phorbol myristate acetate in isolated rat's lungs

   iNOS/GAPDH eNOS/GAPDH
PMA 0 0.23 ± 0.02 0.44 ± 0.04
PMA 4 3.42 ± 0.12* 2.84 ± 0.14*
NAC 0 3.51 ± 0.14 3.02 ± 0.11
NAC 100 0.34 ± 0.04§+ 2.01 ± 0.09§+
NAC 200 0.19 ± 0.06§+ 1.46 ± 0.07§+
NAC 400 0.21 ± 0.04§+ 0.62 ± 0.08§+
  1. Values are means ± SEM (n = 10). The data include 10 isolated lung preparations. *p < 0.05 PMA 4 vs. PMA 0. §p < 0.05 vs. NAC 0 (dose effects of NAC). +p < 0.05 vs. the values of PMA 4. PMA, phorbol myristate acetate; and NAC, niacinamide. The symbols 0 and 4 denote the dose of PMA at μg/g (lung weight), and 0, 100, 200 and 400 of NAC at mg/g (lung weight). The expression of glyceraldehyde phosphate dehydrogenase (GAPDH) was used as an internal standard.
