---|---|---|---|---|
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 | −3.3 ± 0.8 | −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, n = 5, 7, 6, 6, and 5 for rotenone, potassium cyanide (KCN), pentachlorophenol (PCP), PCP + KCN, and rotenone + KCN, respectively. For hyperoxic lungs, n = 4, 5, 6, 5, and 4 for rotenone, KCN, PCP, PCP + KCN, and rotenone + KCN, respectively.
indicates value significantly different from the corresponding normoxic value (t-test, P < 0.05).
