Table I. The Effects of Metabolic Inhibitors and Uncoupler on the Lung Tissue Surface FAD and NADH Fluorescence Signals of Normoxic and Hyperoxic Rats.

Inhibitor/ Uncoupler	FAD %		NADH %
	Normoxic	Hyperoxic	Normoxic	Hyperoxic
Rotenone	0.2 ± 0.2	−0.3 ± 0.3	20.2 ± 2.3	7.5 ± 1.0*
KCN	−6.8 ± 1.6	−5.2 ± 0.5	21.7 ± 2.5	9.2 ± 1.2*
PCP	1.7 ± 0.8	−2.3 ± 1.4*	−19.7 ± 2.1	−20.8± 1.2
PCP + KCN	−9.3 ± 1.0	−4.2 ± 0.7 *	25.7 ± 2.6	9.0 ± 1.0*
Rotenone + KCN	0.8–3.3 ±	−3.8 ± 0.6	4.6 ± 1.0	2.8 ± 1.2

Values are mean ± SE. For the (PCP + KCN) and (rotenone + KCN) treatments, the percentage change due to additional treatment with KCN is calculated relative to the new baseline in the presence of PCP or rotenone, respectively. For normoxic lungs, and 5 for rotenone, potassium cyanide (KCN), pentachlorophenol (PCP), PCP + KCN, and rotenone + KCN, respectively. For hyperoxic lungs , and 4 for rotenone, KCN, PCP, PCP + KCN, and rotenone + KCN, respectively.

^* indicates value significantly different from the corresponding normoxic value (t-test ).
