Table 1 Respiratory Function in Cigarette Smoke-Exposed Mice (persistent exposure to smoke for 52 days) and Sham Mice (exposure to air).

From: Effects of intratracheal administration of nuclear factor-kappaB decoy oligodeoxynucleotides on long-term cigarette smoke-induced lung inflammation and pathology in mice

Test Exposure MEAN ± STD(L/S) Pr > Chi-Square
PIF sham 1.70 ± 0.67 0.7393
  smoke 1.76 ± 0.39  
PEF sham 7.09 ± 0.39 0.9558
  smoke 7.07 ± 0.24  
  1. The data were expressed as means ± STD and analyzed by using the Mann-Whitney U-test. Statistical significance was accepted at P < 0.05.PIF: peak inspiratory flow; PEF: peak expiratory flow. n = 10–15/group.
