The effect of lung perfusion with potassium cyanide (KCN) on the lung tissue surface fluorescence signals and redox ratio (RR) in the presence of rotenone or pentachlorophenol (PCP).

Treatment	N	Change in FAD %	Change in NADH %	Change in RR %
Rotenone + KCN*	6	−3.1 ± 0.86 * (0.049)	4.0 ± 0.86* (0.033)	7.0 ± 0.33 * (<0.001)
PCP + KCN*	4	−9.6 ± 1.1* (<0.001)	27.2 ± 2.05* (<0.001)	38.9 ± 0.75* (<0.001)

Values are mean ± SE. N is the number of lungs for each condition. The percentage change due to additional treatment with KCN is calculated relative to the new baseline in the presence of rotenone or PCP. RR = NADH/FAD

p values are in parentheses (two-tailed student’s t-test, *p < 0.05).
